(i) H and W are married and are domiciled in State A, a community property state. W's Form W-2 for taxable year 2000 showed wage income of $35,000. W also received a Form 1099-INT, “Interest Income,” showing $1,000 W received in taxable year 2000. W's wage income was directly deposited into H and W's joint account, from which H and W paid bills and household expenses. W did not inform H of her interest income or the Form 1099-INT, but W gave H a copy of the W-2 when she received it in January 2001. W did not use her interest income for bills or household expenses. Instead W gave her interest income to her brother, who was unemployed. Neither the separate return filed by H nor the separate return filed by W included the interest income. In 2002, the IRS audits both H and W. The Internal Revenue Service (IRS) may raise section 66(b) as to W's interest income, denying W the Federal income tax benefit resulting from community property law as to this item of income.
(ii) H and W are married and are domiciled in State B, a community property state. For taxable year 2000, H receives $45,000 in wage income that H places in a separate account. H and W maintain separate residences. H's wage income is community income under the laws of State B. That same year, W loses her job, and H pays W's mortgage and household expenses for several months while W seeks employment. Neither H nor W files a return for 2000, the taxable year for which the IRS subsequently audits them. The IRS may not raise section 66(b) and deny H the Federal income tax benefits resulting from the operation of community property law as to H's wage income of $45,000, as H has not treated this income as if H were solely entitled to it.
H and W are married and domiciled in State C, a community property state. H and W do not file a joint return for taxable year 2001. H's and W's earned income for 2001 is community income under the laws of State C. H receives $50,000 in wage income in 2001. In January 2002, H receives a Form W-2 that erroneously states that H earned $45,000 in taxable year 2001. H provides W a copy of H's Form W-2 in February 2002. W files for an extension prior to April 15, 2002. H receives a corrected Form W-2 reflecting wages of $50,000 in May 2002. H provides a copy of the corrected Form W-2 to W in May 2002. W files a separate return in June 2002, but reports one half of $45,000 ($22,500) of wage income that H earned. H files a separate return reporting half of $50,000 ($25,000) in wage income. The IRS audits both H and W. Even if H had acted as if solely entitled to the wage income, the IRS may not raise section 66(b) as to this income because H notified W of the nature and amount of the income prior to the due date of W's return (including extensions).
