Example 1 Item-by-item approach. H and W are married, living together, and domiciled in State A (a community property state). H and W file separate returns for taxable year 2002 on April 15, 2003. H earns $56,000 in wages, and W earns $46,000 in wages, in 2002. H reports half of his wage income as shown on his Form W-2, in the amount of $28,000, and half of W's wage income as shown on her Form W-2, in the amount of $23,000. W reports half of her wage income as shown on her W-2, in the amount of $23,000, and half of H's wage income as shown on his Form W-2, in the amount of $28,000. Neither H nor W reports W's income from her sole proprietorship of $34,000 or W's investment income of $5,000 for taxable year 2002. The Internal Revenue Service (IRS) proposes deficiencies with respect to H's and W's taxable year 2002 returns due to the omission of W's income from her sole proprietorship and investments. H timely requests relief under section 66(c). Because the IRS determines that H satisfies the four requirements of the traditional relief provision of section 66(c) with respect to W's omitted investment income, the IRS grants H's request for relief as to the omitted investment income. The IRS determines that H does not satisfy the four requirements of the traditional relief provision of section 66(c) as to W's sole proprietorship income. The IRS further determines that, under the equitable relief provision of section 66(c), it is not inequitable to hold H liable for the sole proprietorship income. Relief is applicable on an item-by-item basis. Thus, H is liable for the tax on half of his wage income in the amount of $28,000, half of W's wage income in the amount of $23,000, half of W's sole proprietorship income in the amount of $17,000, but none of W's investment income, for which H obtained relief under section 66(c). W is liable for the tax on half of H's wage income in the amount of $28,000, half of W's wage income in the amount of $23,000, half of W's sole proprietorship income in the amount of $17,000, and all of W's investment income in the amount of $5,000, because H obtained relief under section 66(c).
Example 2 Benefit. H and W are married, living together, and domiciled in State B (a community property state). Neither H nor W files a return for taxable year 2000. H earns $60,000 in 2000, which he deposits in a joint account. H and W pay the mortgage payment, household bills, and other family expenses out of the joint account. W earns $20,000 in 2000. W uses a portion of the $20,000 to make monthly loan payments on the family cars, but loses the remainder at the local racetrack. In 2002, the IRS audits H and W. H requests relief under section 66(c), stating that he did not know or have reason to know of W's additional income, as H travels extensively while W handles the family finances. Regardless of whether H had knowledge or reason to know of the source of W's income, H is not eligible for traditional relief under section 66(c) because H benefitted from W's income. H's benefit, the portion of W's income used to make monthly payments on the car loans, was more than a de minimis amount. While this benefit was not in excess of normal support, it is enough to preclude relief under the traditional relief provision of section 66(c). H may still qualify for equitable relief under section 66(c), depending on all of the facts and circumstances.
