Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter B— Computation of Taxable Income › Part I— DEFINITION OF GROSS INCOME, ADJUSTED GROSS INCOME, TAXABLE INCOME, ETC. › § 66
The IRS can refuse to treat money as community property when two people were married at any time in the year but lived apart the whole year, did not file a joint tax return for a tax year that begins or ends in that calendar year, one or both had earned community income, and none of that earned income was moved between them before the end of the year. The IRS can also refuse community property treatment if a spouse acted like the money belonged only to them and did not tell the other spouse, by the tax return due date (including extensions), what kind and how much income it was. The IRS can give relief under rules it makes if someone who did not file jointly failed to report community income that would be treated as the other spouse’s under section 879(a), can show they did not and had no reason to know about it, and it would be unfair to make them include it. Earned income: see section 911(d)(2). Community income: income treated as community under local law. Community property laws: the laws of a State, a foreign country, or a U.S. possession.
