ALLOCATION UNDER SECTION 861 OF RESEARCH AND
EXPERIMENTAL EXPENDITURES
For purposes of subsec. (b) of this section, all
amounts allowable as a deduction for qualified research
and experimental expenditures are to be allocated to
income from sources within the United States and de-
ducted from such income in determining the amount of
taxable income from sources within the United States

§ 863. Special rules for determining source
(a) Allocation under regulations
Items of gross income, expenses, losses, and
deductions, other than those specified in sec-
tions 861(a) and 862(a), shall be allocated or ap-
portioned to sources within or without the
United States, under regulations prescribed by
the Secretary. Where items of gross income are
separately allocated to sources within the
United States, there shall be deducted (for the
purpose of computing the taxable income there-
from) the expenses, losses, and other deductions
properly apportioned or allocated thereto and a
ratable part of other expenses, losses, or other
deductions which cannot definitely be allocated
to some item or class of gross income. The re-
mainder, if any, shall be included in full as tax-
able income from sources within the United
States.
(b) Income partly from within and partly from
without the United States
In the case of gross income derived from
sources partly within and partly without the
United States, the taxable income may first be
computed by deducting the expenses, losses, or
other deductions apportioned or allocated there-
to and a ratable part of any expenses, losses, or
other deductions which cannot definitely be al-
located to some item or class of gross income;
and the portion of such taxable income attrib-
utable to sources within the United States may
be determined by processes or formulas of gen-
eral apportionment prescribed by the Secretary.
Gains, profits, and income—
(1) from services rendered partly within and
partly without the United States,
(2) from the sale or exchange of inventory
property (within the meaning of section
865(i)(1)) produced (in whole or in part) by the
taxpayer within and sold or exchanged with-
out the United States, or produced (in whole
or in part) by the taxpayer without and sold or
exchanged within the United States, or
(3) derived from the purchase of inventory
property (within the meaning of section
865(i)(1)) within a possession of the United
States and its sale or exchange within the
United States,
shall be treated as derived partly from sources
within and partly from sources without the
United States. Gains, profits, and income from
the sale or exchange of inventory property de-
scribed in paragraph (2) shall be allocated and
apportioned between sources within and without
the United States solely on the basis of the pro-
duction activities with respect to the property.
(c) Source rule for certain transportation income
(1) Transportation beginning and ending in the
United States
All transportation income attributable to
transportation which begins and ends in the

rived from personal services performed by
the taxpayer, unless such income is attrib-
utable to transportation which—
(i) begins in the United States and ends
in a possession of the United States, or

For purposes of this subsection, the term
‘‘transportation income’’ means any income
derived from, or in connection with—

lated to the use of a vessel or aircraft.

tainer used in connection with a vessel or air-
craft.

tivities

United States person, shall be sourced out-
side the United States.

to the extent within the United States or
any foreign country or possession of the
United States (as defined in section 638).
For purposes of applying section 638, the ju-
risdiction of any foreign country shall not
include any jurisdiction not recognized by
the United States.
(e) International communications income
(1) Source rules
(A) United States persons
In the case of any United States person, 50
percent of any international communica-
tions income shall be sourced in the United
States and 50 percent of such income shall
be sourced outside the United States.
(B) Foreign persons
(i) In general
Except as provided in regulations or
clause (ii), in the case of any person other
than a United States person, any inter-
national communications income shall be
sourced outside the United States.
(ii) Special rule for income attributable to
office or fixed place of business in the
United States
In the case of any person (other than a
United States person) who maintains an
office or other fixed place of business in
the United States, any international com-
munications income attributable to such
office or other fixed place of business shall
be sourced in the United States.

‘‘international communications income’’ in-
cludes all income derived from the trans-
mission of communications or data from the
United States to any foreign country (or pos-
session of the United States) or from any for-
eign country (or possession of the United
States) to the United States.
