Section 66: Treatment of community income

(a) Treatment of community income where spouses live apart

If—

(1) 2 individuals are married to each other at any time during a calendar year;

(2) such individuals—

(A) live apart at all times during the calendar year, and

(B) do not file a joint return under section 6013 with each other for a taxable year beginning or ending in the calendar year;

(3) one or both of such individuals have earned income for the calendar year which is community income; and

(4) no portion of such earned income is transferred (directly or indirectly) between such individuals before the close of the calendar year,

then, for purposes of this title, any community income of such individuals for the calendar year shall be treated in accordance with the rules provided by section 879(a).

(b) Secretary may disregard community property laws where spouse not notified of community income

The Secretary may disallow the benefits of any community property law to any taxpayer with respect to any income if such taxpayer acted as if solely entitled to such income and failed to notify the taxpayer's spouse before the due date (including extensions) for filing the return for the taxable year in which the income was derived of the nature and amount of such income.

(c) Spouse relieved of liability in certain other cases

Under regulations prescribed by the Secretary, if—

(1) an individual does not file a joint return for any taxable year,

(2) such individual does not include in gross income for such taxable year an item of community income properly includible therein which, in accordance with the rules contained in section 879(a), would be treated as the income of the other spouse,

(3) the individual establishes that he or she did not know of, and had no reason to know of, such item of community income, and

(4) taking into account all facts and circumstances, it is inequitable to include such item of community income in such individual's gross income,

then, for purposes of this title, such item of community income shall be included in the gross income of the other spouse (and not in the gross income of the individual). Under procedures prescribed by the Secretary, if, taking into account all the facts and circumstances, it is inequitable to hold the individual liable for any unpaid tax or any deficiency (or any portion of either) attributable to any item for which relief is not available under the preceding sentence, the Secretary may relieve such individual of such liability.
