§ 1.1312-3 Double exclusion of an item of gross income. ( a ) *Items included in income or with respect to which a tax was paid.* ( 1 ) Paragraph (3)(A) of section 1312 applies if the determination requires the exclusion, from a taxpayer's gross income, of an item included in a return filed by the taxpayer, or with respect to which tax was paid, and which was erroneously excluded or omitted from the gross income of the same taxpayer for another taxable year or of a related taxpayer for the same or another taxable year.
( 2 ) The application of subparagraph (1) of this paragraph may be illustrated by the following examples: Example 1. (i) A taxpayer received payments in 1951 under a contract for the performance of services and included the payments in his return for that year. After the expiration of the period of limitations for the assessment of a deficiency for 1950, the Commissioner issued a notice of deficiency to the taxpayer for the year 1951 based upon adjustments to other items, and the taxpayer filed a petition with the Tax Court of the United States and maintained in the proceedings before the Tax Court that he kept his books on the accrual basis and that the payments received in 1951 were on income that had accrued and was properly taxable in 1950. A final decision of the Tax Court was rendered in 1955 excluding the payments from 1951 income. An adjustment in favor of the Commissioner is authorized with respect to the year 1950, whether or not a tax had been paid on the income reported in the 1951 return. (ii) Assume the same facts as in (i), except that the taxpayer had not included the payments in any return and had not paid a tax thereon. No adjustment would be authorized under section 1312(3)(A) with respect to the year 1950. If the taxpayer, however, had paid a deficiency asserted for 1951 based upon the inclusion of the payments in 1951 income and thereafter successfully sued for refund thereof, an adjustment would be authorized with respect to the year 1950. (See paragraph (b) of this section for circumstances under which correction is authorized with respect to items not included in income and on which a tax was not paid.)
Example 2. A father and son conducted a partnership business, each being entitled to one-half of the net profits. The father included the entire net income of the partnership in his return for 1948, and the son included no portion of this income in his return for that year. Shortly before the expiration of the period of limitations with respect to deficiency assessments and refund claims for both father and son for 1948, the father filed a claim for refund of that portion of his 1948 tax attributable to the half of the partnership income which should have been included in the son's return. The court sustains the claim for refund in 1955. An adjustment is authorized with respect to the son's tax for 1948.
( b ) *Items not included in income and with respect to which the tax was not paid.* ( 1 ) Paragraph (3)(B) of section 1312 applies if the determination requires the exclusion from gross income of an item not included in a return filed by the taxpayer and with respect to which a tax was not paid, but which is includible in the gross income of the same taxpayer for another taxable year, or in the gross income of a related taxpayer for the same or another taxable year. This is one of the two circumstances in which the maintenance of an inconsistent position is not a requirement for an adjustment, but the requirements in paragraph (a) of § 1.1311(b)-2 must be fulfilled (correction not barred at time of erroneous action).
( 2 ) The application of subparagraph (1) of this paragraph may be illustrated by the following examples:
Example 1. The taxpayer, A, who computes his income by use of the accrual method of accounting, performed in 1949 services for which he received payments in 1949 and 1950. He did not include in his return for either 1949 or 1950 the payments which he received in 1950, and he paid no tax with respect to such payments. In 1952 the Commissioner sent a notice of deficiency to A with respect to the year 1949, contending that A should have included all of such payments in his return for that year. A contested the deficiency on the basis that in 1949 he had no accruable right to the payments which he received in 1950. In 1955 (after the expiration of the period of limitations for assessing deficiencies with respect to 1950), the Tax Court sustains A's position. The Commissioner may assess a deficiency for 1950, since a deficiency assessment for that year was not barred when he sent the notice of deficiency with respect to 1949.
Example 2. B and C were partners in 1950, each being entitled to one-half of the profits of the partnership business. During 1950, B received an item of income which he treated as partnership income so that his return for that year reflected only 50 percent of such item. C, however, included no part of such item in any return and paid no tax with respect thereto. In 1952, the Commissioner sent to C a notice of deficiency with respect to 1950, contending that his return for that year should have reflected 50 percent of such item. C contested the deficiency on the basis that such item was not partnership income. In 1955, after the expiration of the period of limitations for assessing deficiencies with respect to 1950, the Tax Court sustained C's position. The Commissioner may assess a deficiency against B with respect to 1950 requiring him to include the entire amount of such item in his income since assessment of the deficiency was not barred when the Commissioner sent the notice of deficiency with respect to such item to C.
