(ii) In the case of a unit which has 1 or more separate bedrooms, 1.5 individuals for each separate bedroom. In the case of a project with respect to which a credit is allowable by reason of this sec- tion and for which financing is provided by a bond described in section 142(a)(7), the im- puted income limitation shall apply in lieu of the otherwise applicable income limita- tion for purposes of applying section 142(d)(4)(B)(ii). (D) Treatment of units occupied by individ- uals whose incomes rise above limit (i) In general Except as provided in clauses (ii), (iii), and (iv), notwithstanding an increase in the income of the occupants of a low-in- come unit above the income limitation ap- plicable under paragraph (1), such unit shall continue to be treated as a low-in- come unit if the income of such occupants initially met such income limitation and such unit continues to be rent-restricted. (ii) Rental of next available unit in case of 20–50 or 40–60 test In the case of a project with respect to which the taxpayer elects the require- ments of subparagraph (A) or (B) of para- graph (1), if the income of the occupants of the unit increases above 140 percent of the income limitation applicable under para- graph (1), clause (i) shall cease to apply to such unit if any residential rental unit in the building (of a size comparable to, or smaller than, such unit) is occupied by a new resident whose income exceeds such income limitation. (iii) Rental of next available unit in case of average income test In the case of a project with respect to which the taxpayer elects the require- ments of subparagraph (C) of paragraph Page 219 TITLE 26—INTERNAL REVENUE CODE § 42 (1), if the income of the occupants of the unit increases above 140 percent of the greater of— (I) 60 percent of area median gross in- come, or (II) the imputed income limitation des- ignated with respect to the unit under paragraph (1)(C)(ii)(I), clause (i) shall cease to apply to any such unit if any residential rental unit in the building (of a size comparable to, or small- er than, such unit) is occupied by a new resident whose income exceeds the limita- tion described in clause (v). (iv) Deep rent skewed projects In the case of a project described in sec- tion 142(d)(4)(B), clause (ii) or (iii), which- ever is applicable, shall be applied by sub- stituting ‘‘170 percent’’ for ‘‘140 percent’’, and— (I) in the case of clause (ii), by sub- stituting ‘‘any low-income unit in the building is occupied by a new resident whose income exceeds 40 percent of area median gross income’’ for ‘‘any residen- tial rental unit’’ and all that follows in such clause, and (II) in the case of clause (iii), by sub- stituting ‘‘any low-income unit in the building is occupied by a new resident whose income exceeds the lesser of 40 percent of area median gross income or the imputed income limitation des- ignated with respect to such unit under paragraph (1)(C)(ii)(I)’’ for ‘‘any residen- tial rental unit’’ and all that follows in such clause. (v) Limitation described For purposes of clause (iii), the limita- tion described in this clause with respect to any unit is— (I) the imputed income limitation des- ignated with respect to such unit under paragraph (1)(C)(ii)(I), in the case of a unit which was taken into account as a low-income unit prior to becoming va- cant, and (II) the imputed income limitation which would have to be designated with respect to such unit under such para- graph in order for the project to con- tinue to meet the requirements of para- graph (1)(C)(ii)(II), in the case of any other unit. (E) Units where Federal rental assistance is reduced as tenant’s income increases If the gross rent with respect to a residen- tial unit exceeds the limitation under sub- paragraph (A) by reason of the fact that the income of the occupants thereof exceeds the income limitation applicable under para- graph (1), such unit shall, nevertheless, be treated as a rent-restricted unit for purposes of paragraph (1) if— (i) a Federal rental assistance payment described in subparagraph (B)(i) is made with respect to such unit or its occupants, and (ii) the sum of such payment and the gross rent with respect to such unit does not exceed the sum of the amount of such payment which would be made and the gross rent which would be payable with re- spect to such unit if— (I) the income of the occupants thereof did not exceed the income limitation ap- plicable under paragraph (1), and (II) such units were rent-restricted within the meaning of subparagraph (A). The preceding sentence shall apply to any unit only if the result described in clause (ii) is required by Federal statute as of the date of the enactment of this subparagraph and as of the date the Federal rental assistance payment is made. (3) Date for meeting requirements (A) In general Except as otherwise provided in this para- graph, a building shall be treated as a quali- fied low-income building only if the project (of which such building is a part) meets the requirements of paragraph (1) not later than the close of the 1st year of the credit period for such building. (B) Buildings which rely on later buildings for qualification (i) In general In determining whether a building (here- inafter in this subparagraph referred to as the ‘‘prior building’’) is a qualified low-in- come building, the taxpayer may take into account 1 or more additional buildings placed in service during the 12-month pe- riod described in subparagraph (A) with re- spect to the prior building only if the tax- payer elects to apply clause (ii) with re- spect to each additional building taken into account. (ii) Treatment of elected buildings In the case of a building which the tax- payer elects to take into account under clause (i), the period under subparagraph (A) for such building shall end at the close of the 12-month period applicable to the prior building. (iii) Date prior building is treated as placed in service For purposes of determining the credit period and the compliance period for the prior building, the prior building shall be treated for purposes of this section as placed in service on the most recent date any additional building elected by the tax- payer (with respect to such prior building) was placed in service. (C) Special rule A building— (i) other than the 1st building placed in service as part of a project, and (ii) other than a building which is placed in service during the 12-month period de- scribed in subparagraph (A) with respect to a prior building which becomes a qualified low-income building, shall in no event be treated as a qualified low-income building unless the project is a Page 220 TITLE 26—INTERNAL REVENUE CODE § 42 qualified low-income housing project (with- out regard to such building) on the date such building is placed in service. (D) Projects with more than 1 building must be identified For purposes of this section, a project shall be treated as consisting of only 1 build- ing unless, before the close of the 1st cal- endar year in the project period (as defined in subsection (h)(1)(F)(ii)), each building which is (or will be) part of such project is identified in such form and manner as the Secretary may provide. (4) Certain rules made applicable Paragraphs (2) (other than subparagraph (A) thereof), (3), (4), (5), (6), and (7) of section 142(d), and section 6652(j), shall apply for pur- poses of determining whether any project is a qualified low-income housing project and whether any unit is a low-income unit; except that, in applying such provisions for such pur- poses, the term ‘‘gross rent’’ shall have the meaning given such term by paragraph (2)(B) of this subsection. (5) Election to treat building after compliance period as not part of a project For purposes of this section, the taxpayer may elect to treat any building as not part of a qualified low-income housing project for any period beginning after the compliance period for such building. (6) Special rule where de minimis equity con- tribution Property shall not be treated as failing to be residential rental property for purposes of this section merely because the occupant of a resi- dential unit in the project pays (on a vol- untary basis) to the lessor a de minimis amount to be held toward the purchase by such occupant of a residential unit in such project if— (A) all amounts so paid are refunded to the occupant on the cessation of his occupancy of a unit in the project, and (B) the purchase of the unit is not per- mitted until after the close of the compli- ance period with respect to the building in which the unit is located. Any amount paid to the lessor as described in the preceding sentence shall be included in gross rent under paragraph (2) for purposes of determining whether the unit is rent-re- stricted. (7) Scattered site projects Buildings which would (but for their lack of proximity) be treated as a project for purposes of this section shall be so treated if all of the dwelling units in each of the buildings are rent-restricted (within the meaning of para- graph (2)) residential rental units. (8) Waiver of certain de minimis errors and re- certifications On application by the taxpayer, the Sec- retary may waive— (A) any recapture under subsection (j) in the case of any de minimis error in com- plying with paragraph (1), or (B) any annual recertification of tenant in- come for purposes of this subsection, if the entire building is occupied by low-income tenants. (9) Clarification of general public use require- ment A project does not fail to meet the general public use requirement solely because of occu- pancy restrictions or preferences that favor tenants— (A) with special needs, (B) who are members of a specified group under a Federal program or State program or policy that supports housing for such a specified group, or (C) who are involved in artistic or literary activities. (h) Limitation on aggregate credit allowable with respect to projects located in a State (1) Credit may not exceed credit amount allo- cated to building (A) In general The amount of the credit determined under this section for any taxable year with respect to any building shall not exceed the housing credit dollar amount allocated to such building under this subsection. (B) Time for making allocation Except in the case of an allocation which meets the requirements of subparagraph (C), (D), (E), or (F), an allocation shall be taken into account under subparagraph (A) only if it is made not later than the close of the cal- endar year in which the building is placed in service. (C) Exception where binding commitment An allocation meets the requirements of this subparagraph if there is a binding com- mitment (not later than the close of the cal- endar year in which the building is placed in service) by the housing credit agency to al- locate a specified housing credit dollar amount to such building beginning in a spec- ified later taxable year. (D) Exception where increase in qualified basis (i) In general An allocation meets the requirements of this subparagraph if such allocation is made not later than the close of the cal- endar year in which ends the taxable year to which it will 1st apply but only to the extent the amount of such allocation does not exceed the limitation under clause (ii). (ii) Limitation The limitation under this clause is the amount of credit allowable under this sec- tion (without regard to this subsection) for a taxable year with respect to an increase in the qualified basis of the building equal to the excess of— (I) the qualified basis of such building as of the close of the 1st taxable year to which such allocation will apply, over (II) the qualified basis of such building as of the close of the 1st taxable year to Page 221 TITLE 26—INTERNAL REVENUE CODE § 42 which the most recent prior housing credit allocation with respect to such building applied. (iii) Housing credit dollar amount reduced by full allocation Notwithstanding clause (i), the full amount of the allocation shall be taken into account under paragraph (2). (E) Exception where 10 percent of cost in- curred (i) In general An allocation meets the requirements of this subparagraph if such allocation is made with respect to a qualified building which is placed in service not later than the close of the second calendar year fol- lowing the calendar year in which the allo- cation is made. (ii) Qualified building For purposes of clause (i), the term ‘‘qualified building’’ means any building which is part of a project if the taxpayer’s basis in such project (as of the date which is 1 year after the date that the allocation was made) is more than 10 percent of the taxpayer’s reasonably expected basis in such project (as of the close of the second calendar year referred to in clause (i)). Such term does not include any existing building unless a credit is allowable under subsection (e) for rehabilitation expendi- tures paid or incurred by the taxpayer with respect to such building for a taxable year ending during the second calendar year referred to in clause (i) or the prior taxable year. (F) Allocation of credit on a project basis (i) In general In the case of a project which includes (or will include) more than 1 building, an allocation meets the requirements of this subparagraph if— (I) the allocation is made to the project for a calendar year during the project period, (II) the allocation only applies to buildings placed in service during or after the calendar year for which the al- location is made, and (III) the portion of such allocation which is allocated to any building in such project is specified not later than the close of the calendar year in which the building is placed in service. (ii) Project period For purposes of clause (i), the term ‘‘project period’’ means the period— (I) beginning with the 1st calendar year for which an allocation may be made for the 1st building placed in serv- ice as part of such project, and (II) ending with the calendar year the last building is placed in service as part of such project. (2) Allocated credit amount to apply to all tax- able years ending during or after credit al- location year Any housing credit dollar amount allocated to any building for any calendar year— (A) shall apply to such building for all tax- able years in the compliance period ending during or after such calendar year, and (B) shall reduce the aggregate housing credit dollar amount of the allocating agen- cy only for such calendar year. (3) Housing credit dollar amount for agencies (A) In general The aggregate housing credit dollar amount which a housing credit agency may allocate for any calendar year is the portion of the State housing credit ceiling allocated under this paragraph for such calendar year to such agency. (B) State ceiling initially allocated to State housing credit agencies Except as provided in subparagraphs (D) and (E), the State housing credit ceiling for each calendar year shall be allocated to the housing credit agency of such State. If there is more than 1 housing credit agency of a State, all such agencies shall be treated as a single agency. (C) State housing credit ceiling The State housing credit ceiling applicable to any State for any calendar year shall be an amount equal to the sum of— (i) the unused State housing credit ceil- ing (if any) of such State for the preceding calendar year, (ii) the greater of— (I) $1.75 multiplied by the State popu- lation, or (II) $2,000,000, (iii) the amount of State housing credit ceiling returned in the calendar year, plus (iv) the amount (if any) allocated under subparagraph (D) to such State by the Sec- retary. For purposes of clause (i), the unused State housing credit ceiling for any calendar year is the excess (if any) of the sum of the amounts described in clauses (ii) through (iv) over the aggregate housing credit dollar amount allocated for such year. For pur- poses of clause (iii), the amount of State housing credit ceiling returned in the cal- endar year equals the housing credit dollar amount previously allocated within the State to any project which fails to meet the 10 percent test under paragraph (1)(E)(ii) on a date after the close of the calendar year in which the allocation was made or which does not become a qualified low-income housing project within the period required by this section or the terms of the allocation or to any project with respect to which an alloca- tion is cancelled by mutual consent of the housing credit agency and the allocation re- cipient. (D) Unused housing credit carryovers allo- cated among certain States (i) In general The unused housing credit carryover of a State for any calendar year shall be as- signed to the Secretary for allocation among qualified States for the succeeding calendar year. Page 222 TITLE 26—INTERNAL REVENUE CODE § 42 (ii) Unused housing credit carryover For purposes of this subparagraph, the unused housing credit carryover of a State for any calendar year is the excess (if any) of— (I) the unused State housing credit ceiling for the year preceding such year, over (II) the aggregate housing credit dollar amount allocated for such year. (iii) Formula for allocation of unused hous- ing credit carryovers among qualified States The amount allocated under this sub- paragraph to a qualified State for any cal- endar year shall be the amount determined by the Secretary to bear the same ratio to the aggregate unused housing credit carryovers of all States for the preceding calendar year as such State’s population for the calendar year bears to the popu- lation of all qualified States for the cal- endar year. For purposes of the preceding sentence, population shall be determined in accordance with section 146(j). (iv) Qualified State For purposes of this subparagraph, the term ‘‘qualified State’’ means, with re- spect to a calendar year, any State— (I) which allocated its entire State housing credit ceiling for the preceding calendar year, and (II) for which a request is made (not later than May 1 of the calendar year) to receive an allocation under clause (iii). (E) Special rule for States with constitutional home rule cities For purposes of this subsection— (i) In general The aggregate housing credit dollar amount for any constitutional home rule city for any calendar year shall be an amount which bears the same ratio to the State housing credit ceiling for such cal- endar year as— (I) the population of such city, bears to (II) the population of the entire State. (ii) Coordination with other allocations In the case of any State which contains 1 or more constitutional home rule cities, for purposes of applying this paragraph with respect to housing credit agencies in such State other than constitutional home rule cities, the State housing credit ceiling for any calendar year shall be reduced by the aggregate housing credit dollar amounts determined for such year for all constitutional home rule cities in such State. (iii) Constitutional home rule city For purposes of this paragraph, the term ‘‘constitutional home rule city’’ has the meaning given such term by section 146(d)(3)(C). (F) State may provide for different allocation Rules similar to the rules of section 146(e) (other than paragraph (2)(B) thereof) shall apply for purposes of this paragraph. (G) Population For purposes of this paragraph, population shall be determined in accordance with sec- tion 146(j). (H) Cost-of-living adjustment (i) In general In the case of a calendar year after 2002, the $2,000,000 and $1.75 amounts in subpara- graph (C) shall each be increased by an amount equal to— (I) such dollar amount, multiplied by (II) the cost-of-living adjustment de- termined under section 1(f)(3) for such calendar year by substituting ‘‘calendar year 2001’’ for ‘‘calendar year 2016’’ in subparagraph (A)(ii) thereof. (ii) Rounding (I) In the case of the $2,000,000 amount, any increase under clause (i) which is not a multiple of $5,000 shall be rounded to the next lowest multiple of $5,000. (II) In the case of the $1.75 amount, any increase under clause (i) which is not a multiple of 5 cents shall be rounded to the next lowest multiple of 5 cents. (I) Increase in State housing credit ceiling for 2018, 2019, 2020, and 2021 In the case of calendar years 2018, 2019, 2020, and 2021, each of the dollar amounts in effect under clauses (I) and (II) of subpara- graph (C)(ii) for any calendar year (after any increase under subparagraph (H)) shall be in- creased by multiplying such dollar amount by 1.125. (4) Credit for buildings financed by tax-exempt bonds subject to volume cap not taken into account (A) In general Paragraph (1) shall not apply to the por- tion of any credit allowable under sub- section (a) which is attributable to eligible basis financed by any obligation the interest on which is exempt from tax under section 103 if— (i) such obligation is taken into account under section 146, and (ii) principal payments on such financing are applied within a reasonable period to redeem obligations the proceeds of which were used to provide such financing or such financing is refunded as described in section 146(i)(6). (B) Special rule where 50 percent or more of building is financed with tax-exempt bonds subject to volume cap For purposes of subparagraph (A), if 50 per- cent or more of the aggregate basis of any building and the land on which the building is located is financed by any obligation de- scribed in subparagraph (A), paragraph (1) shall not apply to any portion of the credit allowable under subsection (a) with respect to such building. Page 223 TITLE 26—INTERNAL REVENUE CODE § 42 (5) Portion of State ceiling set-aside for certain projects involving qualified nonprofit orga- nizations (A) In general Not more than 90 percent of the State housing credit ceiling for any State for any calendar year shall be allocated to projects other than qualified low-income housing projects described in subparagraph (B). (B) Projects involving qualified nonprofit or- ganizations For purposes of subparagraph (A), a quali- fied low-income housing project is described in this subparagraph if a qualified nonprofit organization is to own an interest in the project (directly or through a partnership) and materially participate (within the meaning of section 469(h)) in the develop- ment and operation of the project through- out the compliance period.

(D) Treatment of certain subsidiaries (i) In general For purposes of this paragraph, a quali- fied nonprofit organization shall be treat- ed as satisfying the ownership and mate- rial participation test of subparagraph (B) if any qualified corporation in which such organization holds stock satisfies such test. (ii) Qualified corporation For purposes of clause (i), the term ‘‘qualified corporation’’ means any cor- poration if 100 percent of the stock of such corporation is held by 1 or more qualified nonprofit organizations at all times during the period such corporation is in existence. (E) State may not override set-aside Nothing in subparagraph (F) of paragraph (3) shall be construed to permit a State not to comply with subparagraph (A) of this paragraph. (6) Buildings eligible for credit only if min- imum long-term commitment to low-in- come housing (A) In general No credit shall be allowed by reason of this section with respect to any building for the taxable year unless an extended low-income housing commitment is in effect as of the end of such taxable year. (B) Extended low-income housing commit- ment For purposes of this paragraph, the term ‘‘extended low-income housing commit- ment’’ means any agreement between the taxpayer and the housing credit agency— (i) which requires that the applicable fraction (as defined in subsection (c)(1)) for the building for each taxable year in the extended use period will not be less than the applicable fraction specified in such agreement and which prohibits the actions described in subclauses (I) and (II) of sub- paragraph (E)(ii), (ii) which allows individuals who meet the income limitation applicable to the building under subsection (g) (whether pro- spective, present, or former occupants of the building) the right to enforce in any State court the requirement and prohibi- tions of clause (i), (iii) which prohibits the disposition to any person of any portion of the building to which such agreement applies unless all of the building to which such agreement applies is disposed of to such person, (iv) which prohibits the refusal to lease to a holder of a voucher or certificate of eligibility under section 8 of the United States Housing Act of 1937 because of the status of the prospective tenant as such a holder, (v) which is binding on all successors of the taxpayer, and (vi) which, with respect to the property, is recorded pursuant to State law as a re- strictive covenant. (C) Allocation of credit may not exceed amount necessary to support commit- ment (i) In general The housing credit dollar amount allo- cated to any building may not exceed the amount necessary to support the applica- ble fraction specified in the extended low- income housing commitment for such building, including any increase in such fraction pursuant to the application of subsection (f)(3) if such increase is re- flected in an amended low-income housing commitment. (ii) Buildings financed by tax-exempt bonds If paragraph (4) applies to any building the amount of credit allowed in any tax- able year may not exceed the amount nec- essary to support the applicable fraction specified in the extended low-income hous- ing commitment for such building. Such commitment may be amended to increase such fraction.

Page 224 TITLE 26—INTERNAL REVENUE CODE § 42 (E) Exceptions if foreclosure or if no buyer willing to maintain low-income status (i) In general The extended use period for any building shall terminate— (I) on the date the building is acquired by foreclosure (or instrument in lieu of foreclosure) unless the Secretary deter- mines that such acquisition is part of an arrangement with the taxpayer a pur- pose of which is to terminate such pe- riod, or (II) on the last day of the period speci- fied in subparagraph (I) if the housing credit agency is unable to present during such period a qualified contract for the acquisition of the low-income portion of the building by any person who will con- tinue to operate such portion as a quali- fied low-income building. Subclause (II) shall not apply to the extent more stringent requirements are provided in the agreement or in State law. (ii) Eviction, etc. of existing low-income tenants not permitted The termination of an extended use pe- riod under clause (i) shall not be construed to permit before the close of the 3-year pe- riod following such termination— (I) the eviction or the termination of tenancy (other than for good cause) of an existing tenant of any low-income unit, or (II) any increase in the gross rent with respect to such unit not otherwise per- mitted under this section.

(G) Adjusted investor equity (i) In general For purposes of subparagraph (E), the term ‘‘adjusted investor equity’’ means, with respect to any calendar year, the ag- gregate amount of cash taxpayers invested with respect to the project increased by the amount equal to— (I) such amount, multiplied by (II) the cost-of-living adjustment for such calendar year, determined under section 1(f)(3) by substituting the base calendar year for ‘‘calendar year 2016’’ in subparagraph (A)(ii) thereof. An amount shall be taken into account as an investment in the project only to the extent there was an obligation to invest such amount as of the beginning of the credit period and to the extent such amount is reflected in the adjusted basis of the project. (ii) Cost-of-living increases in excess of 5 percent not taken into account Under regulations prescribed by the Sec- retary, if the C-CPI-U for any calendar year (as defined in section 1(f)(6)) exceeds the C-CPI-U for the preceding calendar year by more than 5 percent, the C-CPI-U for the base calendar year shall be in- creased such that such excess shall never be taken into account under clause (i). In the case of a base calendar year before 2017, the C-CPI-U for such year shall be de- termined by multiplying the CPI for such year by the amount determined under sec- tion 1(f)(3)(B).

(D) Housing credit agency to specify applica- ble percentage and maximum qualified basis In allocating a housing credit dollar amount to any building, the housing credit agency shall specify the applicable percent- age and the maximum qualified basis which may be taken into account under this sec- tion with respect to such building. The ap- plicable percentage and maximum qualified basis so specified shall not exceed the appli- cable percentage and qualified basis deter- mined under this section without regard to this subsection.

(9) Coordination with low-income housing grants (A) Reduction in State housing credit ceiling for low-income housing grants received in 2009 For purposes of this section, the amounts described in clauses (i) through (iv) of sub- section (h)(3)(C) with respect to any State for 2009 shall each be reduced by so much of such amount as is taken into account in de- termining the amount of any grant to such State under section 1602 of the American Re- covery and Reinvestment Tax Act of 2009. (B) Special rule for basis Basis of a qualified low-income building shall not be reduced by the amount of any grant described in subparagraph (A). (j) Recapture of credit (1) In general If— (A) as of the close of any taxable year in the compliance period, the amount of the qualified basis of any building with respect to the taxpayer is less than (B) the amount of such basis as of the close of the preceding taxable year, then the taxpayer’s tax under this chapter for the taxable year shall be increased by the credit recapture amount. (2) Credit recapture amount For purposes of paragraph (1), the credit re- capture amount is an amount equal to the sum of— (A) the aggregate decrease in the credits allowed to the taxpayer under section 38 for all prior taxable years which would have re- sulted if the accelerated portion of the cred- it allowable by reason of this section were not allowed for all prior taxable years with respect to the excess of the amount de- scribed in paragraph (1)(B) over the amount described in paragraph (1)(A), plus (B) interest at the overpayment rate es- tablished under section 6621 on the amount determined under subparagraph (A) for each prior taxable year for the period beginning on the due date for filing the return for the prior taxable year involved. No deduction shall be allowed under this chap- ter for interest described in subparagraph (B). (3) Accelerated portion of credit For purposes of paragraph (2), the acceler- ated portion of the credit for the prior taxable years with respect to any amount of basis is the excess of— (A) the aggregate credit allowed by reason of this section (without regard to this sub- section) for such years with respect to such basis, over (B) the aggregate credit which would be al- lowable by reason of this section for such years with respect to such basis if the aggre- gate credit which would (but for this sub- section) have been allowable for the entire compliance period were allowable ratably over 15 years. (4) Special rules (A) Tax benefit rule The tax for the taxable year shall be in- creased under paragraph (1) only with re- spect to credits allowed by reason of this section which were used to reduce tax liabil- ity. In the case of credits not so used to re- duce tax liability, the carryforwards and carrybacks under section 39 shall be appro- priately adjusted. (B) Only basis for which credit allowed taken into account Qualified basis shall be taken into account under paragraph (1)(B) only to the extent such basis was taken into account in deter- mining the credit under subsection (a) for the preceding taxable year referred to in such paragraph. (C) No recapture of additional credit allow- able by reason of subsection (f)(3) Paragraph (1) shall apply to a decrease in qualified basis only to the extent such de- crease exceeds the amount of qualified basis with respect to which a credit was allowable for the taxable year referred to in paragraph (1)(B) by reason of subsection (f)(3). (D) No credits against tax Any increase in tax under this subsection shall not be treated as a tax imposed by this chapter for purposes of determining the amount of any credit under this chapter. (E) No recapture by reason of casualty loss The increase in tax under this subsection shall not apply to a reduction in qualified basis by reason of a casualty loss to the ex- tent such loss is restored by reconstruction or replacement within a reasonable period established by the Secretary. (F) No recapture where de minimis changes in floor space The Secretary may provide that the in- crease in tax under this subsection shall not apply with respect to any building if— (i) such increase results from a de mini- mis change in the floor space fraction under subsection (c)(1), and (ii) the building is a qualified low-in- come building after such change. (5) Certain partnerships treated as the tax- payer (A) In general For purposes of applying this subsection to a partnership to which this paragraph ap- plies— Page 228 TITLE 26—INTERNAL REVENUE CODE § 42 (i) such partnership shall be treated as the taxpayer to which the credit allowable under subsection (a) was allowed, (ii) the amount of such credit allowed shall be treated as the amount which would have been allowed to the partner- ship were such credit allowable to such partnership, (iii) paragraph (4)(A) shall not apply, and (iv) the amount of the increase in tax under this subsection for any taxable year shall be allocated among the partners of such partnership in the same manner as such partnership’s taxable income for such year is allocated among such partners. (B) Partnerships to which paragraph applies This paragraph shall apply to any partner- ship which has 35 or more partners unless the partnership elects not to have this para- graph apply. (C) Special rules (i) Husband and wife treated as 1 partner For purposes of subparagraph (B)(i), a husband and wife (and their estates) shall be treated as 1 partner. (ii) Election irrevocable Any election under subparagraph (B), once made, shall be irrevocable. (6) No recapture on disposition of building which continues in qualified use (A) In general The increase in tax under this subsection shall not apply solely by reason of the dis- position of a building (or an interest therein) if it is reasonably expected that such build- ing will continue to be operated as a quali- fied low-income building for the remaining compliance period with respect to such building. (B) Statute of limitations If a building (or an interest therein) is dis- posed of during any taxable year and there is any reduction in the qualified basis of such building which results in an increase in tax under this subsection for such taxable or any subsequent taxable year, then— (i) the statutory period for the assess- ment of any deficiency with respect to such increase in tax shall not expire before the expiration of 3 years from the date the Secretary is notified by the taxpayer (in such manner as the Secretary may pre- scribe) of such reduction in qualified basis, and (ii) such deficiency may be assessed be- fore the expiration of such 3-year period notwithstanding the provisions of any other law or rule of law which would oth- erwise prevent such assessment. (k) Application of at-risk rules For purposes of this section— (1) In general Except as otherwise provided in this sub- section, rules similar to the rules of section 49(a)(1) (other than subparagraphs (D)(ii)(II) and (D)(iv)(I) thereof), section 49(a)(2), and sec- tion 49(b)(1) shall apply in determining the qualified basis of any building in the same manner as such sections apply in determining the credit base of property. (2) Special rules for determining qualified per- son For purposes of paragraph (1)— (A) In general If the requirements of subparagraphs (B), (C), and (D) are met with respect to any fi- nancing borrowed from a qualified nonprofit organization (as defined in subsection (h)(5)), the determination of whether such financing is qualified commercial financing with re- spect to any qualified low-income building shall be made without regard to whether such organization— (i) is actively and regularly engaged in the business of lending money, or (ii) is a person described in section 49(a)(1)(D)(iv)(II). (B) Financing secured by property The requirements of this subparagraph are met with respect to any financing if such fi- nancing is secured by the qualified low-in- come building, except that this subpara- graph shall not apply in the case of a feder- ally assisted building described in subsection (d)(6)(C) if— (i) a security interest in such building is not permitted by a Federal agency holding or insuring the mortgage secured by such building, and (ii) the proceeds from the financing (if any) are applied to acquire or improve such building. (C) Portion of building attributable to financ- ing The requirements of this subparagraph are met with respect to any financing for any taxable year in the compliance period if, as of the close of such taxable year, not more than 60 percent of the eligible basis of the qualified low-income building is attributable to such financing (reduced by the principal and interest of any governmental financing which is part of a wrap-around mortgage in- volving such financing). (D) Repayment of principal and interest The requirements of this subparagraph are met with respect to any financing if such fi- nancing is fully repaid on or before the ear- liest of— (i) the date on which such financing ma- tures, (ii) the 90th day after the close of the compliance period with respect to the qualified low-income building, or (iii) the date of its refinancing or the sale of the building to which such financ- ing relates. In the case of a qualified nonprofit organiza- tion which is not described in section 49(a)(1)(D)(iv)(II) with respect to a building, clause (ii) of this subparagraph shall be ap- plied as if the date described therein were the 90th day after the earlier of the date the Page 229 TITLE 26—INTERNAL REVENUE CODE § 42 building ceases to be a qualified low-income building or the date which is 15 years after the close of a compliance period with respect thereto. (3) Present value of financing If the rate of interest on any financing de- scribed in paragraph (2)(A) is less than the rate which is 1 percentage point below the ap- plicable Federal rate as of the time such fi- nancing is incurred, then the qualified basis (to which such financing relates) of the quali- fied low-income building shall be the present value of the amount of such financing, using as the discount rate such applicable Federal rate. For purposes of the preceding sentence, the rate of interest on any financing shall be determined by treating interest to the extent of government subsidies as not payable. (4) Failure to fully repay (A) In general To the extent that the requirements of paragraph (2)(D) are not met, then the tax- payer’s tax under this chapter for the tax- able year in which such failure occurs shall be increased by an amount equal to the ap- plicable portion of the credit under this sec- tion with respect to such building, increased by an amount of interest for the period— (i) beginning with the due date for the filing of the return of tax imposed by chap- ter 1 for the 1st taxable year for which such credit was allowable, and (ii) ending with the due date for the tax- able year in which such failure occurs, determined by using the underpayment rate and method under section 6621. (B) Applicable portion For purposes of subparagraph (A), the term ‘‘applicable portion’’ means the aggregate decrease in the credits allowed to a taxpayer under section 38 for all prior taxable years which would have resulted if the eligible basis of the building were reduced by the amount of financing which does not meet re- quirements of paragraph (2)(D). (C) Certain rules to apply Rules similar to the rules of subparagraphs (A) and (D) of subsection (j)(4) shall apply for purposes of this subsection. (l) Certifications and other reports to Secretary (1) Certification with respect to 1st year of credit period Following the close of the 1st taxable year in the credit period with respect to any quali- fied low-income building, the taxpayer shall certify to the Secretary (at such time and in such form and in such manner as the Sec- retary prescribes)— (A) the taxable year, and calendar year, in which such building was placed in service, (B) the adjusted basis and eligible basis of such building as of the close of the 1st year of the credit period, (C) the maximum applicable percentage and qualified basis permitted to be taken into account by the appropriate housing credit agency under subsection (h), (D) the election made under subsection (g) with respect to the qualified low-income housing project of which such building is a part, and (E) such other information as the Sec- retary may require. In the case of a failure to make the certifi- cation required by the preceding sentence on the date prescribed therefor, unless it is shown that such failure is due to reasonable cause and not to willful neglect, no credit shall be allowable by reason of subsection (a) with re- spect to such building for any taxable year ending before such certification is made. (2) Annual reports to the Secretary The Secretary may require taxpayers to sub- mit an information return (at such time and in such form and manner as the Secretary pre- scribes) for each taxable year setting forth— (A) the qualified basis for the taxable year of each qualified low-income building of the taxpayer, (B) the information described in paragraph (1)(C) for the taxable year, and (C) such other information as the Sec- retary may require. The penalty under section 6652(j) shall apply to any failure to submit the return required by the Secretary under the preceding sentence on the date prescribed therefor. (3) Annual reports from housing credit agen- cies Each agency which allocates any housing credit amount to any building for any cal- endar year shall submit to the Secretary (at such time and in such manner as the Sec- retary shall prescribe) an annual report speci- fying— (A) the amount of housing credit amount allocated to each building for such year, (B) sufficient information to identify each such building and the taxpayer with respect thereto, and (C) such other information as the Sec- retary may require. The penalty under section 6652(j) shall apply to any failure to submit the report required by the preceding sentence on the date prescribed therefor. (m) Responsibilities of housing credit agencies (1) Plans for allocation of credit among projects (A) In general Notwithstanding any other provision of this section, the housing credit dollar amount with respect to any building shall be zero unless— (i) such amount was allocated pursuant to a qualified allocation plan of the hous- ing credit agency which is approved by the governmental unit (in accordance with rules similar to the rules of section 147(f)(2) (other than subparagraph (B)(ii) thereof)) of which such agency is a part, (ii) such agency notifies the chief execu- tive officer (or the equivalent) of the local jurisdiction within which the building is Page 230 TITLE 26—INTERNAL REVENUE CODE § 42 located of such project and provides such individual a reasonable opportunity to comment on the project, (iii) a comprehensive market study of the housing needs of low-income individ- uals in the area to be served by the project is conducted before the credit allocation is made and at the developer’s expense by a disinterested party who is approved by such agency, and (iv) a written explanation is available to the general public for any allocation of a housing credit dollar amount which is not made in accordance with established prior- ities and selection criteria of the housing credit agency. (B) Qualified allocation plan For purposes of this paragraph, the term ‘‘qualified allocation plan’’ means any plan— (i) which sets forth selection criteria to be used to determine housing priorities of the housing credit agency which are appro- priate to local conditions, (ii) which also gives preference in allo- cating housing credit dollar amounts among selected projects to— (I) projects serving the lowest income tenants, (II) projects obligated to serve quali- fied tenants for the longest periods, and (III) projects which are located in qualified census tracts (as defined in sub- section (d)(5)(B)(ii)) and the development of which contributes to a concerted com- munity revitalization plan, and (iii) which provides a procedure that the agency (or an agent or other private con- tractor of such agency) will follow in mon- itoring for noncompliance with the provi- sions of this section and in notifying the Internal Revenue Service of such non- compliance which such agency becomes aware of and in monitoring for noncompli- ance with habitability standards through regular site visits. (C) Certain selection criteria must be used The selection criteria set forth in a quali- fied allocation plan must include (i) project location, (ii) housing needs characteristics, (iii) project characteristics, including whether the project includes the use of ex- isting housing as part of a community re- vitalization plan, (iv) sponsor characteristics, (v) tenant populations with special hous- ing needs, (vi) public housing waiting lists, (vii) tenant populations of individuals with children, (viii) projects intended for eventual ten- ant ownership, (ix) the energy efficiency of the project, and (x) the historic nature of the project.

(2) Credit allocated to building not to exceed amount necessary to assure project feasi- bility (A) In general The housing credit dollar amount allo- cated to a project shall not exceed the amount the housing credit agency deter- mines is necessary for the financial feasi- bility of the project and its viability as a qualified low-income housing project throughout the credit period. (B) Agency evaluation In making the determination under sub- paragraph (A), the housing credit agency shall consider— (i) the sources and uses of funds and the total financing planned for the project, (ii) any proceeds or receipts expected to be generated by reason of tax benefits, (iii) the percentage of the housing credit dollar amount used for project costs other than the cost of intermediaries, and (iv) the reasonableness of the develop- mental and operational costs of the project. Clause (iii) shall not be applied so as to im- pede the development of projects in hard-to- develop areas. Such a determination shall not be construed to be a representation or warranty as to the feasibility or viability of the project. (C) Determination made when credit amount applied for and when building placed in service (i) In general A determination under subparagraph (A) shall be made as of each of the following times: (I) The application for the housing credit dollar amount.
