Example 1 Acting as if solely entitled to income.
Example 2 Notification of nature and amount of the income. 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).
