26 CFR § 25.2504-1 - Taxable gifts for preceding calendar periods.
(a) In order to determine the correct gift tax liability for any calendar period it is necessary to ascertain the correct amount, if any, of the aggregate sum of the taxable gifts for each of the “preceding calendar periods” (as defined in § 25.2502-1(c)(2)). See paragraph (a) of § 25.2502-1. The term “aggregate sum of the taxable gifts for each of the preceding calendar periods” means the correct aggregate of such gifts, not necessarily that returned for those calendar periods and in respect of which tax was paid. All transfers that constituted gifts in prior calendar periods under the laws, including the provisions of law relating to exclusions from gifts, in effect at the time the transfers were made are included in determining the amount of taxable gifts for preceding calendar periods. The deductions other than for the specific exemption (see paragraph (b) of this section) allowed by the laws in effect at the time the transfers were made also are taken into account in determining the aggregate sum of the taxable gifts for preceding calendar periods. (The allowable exclusion from a gift is $5,000 for years before 1939, $4,000 for the calendar years 1939 through 1942, $3,000 for the calendar years 1943 through 1981, and $10,000 thereafter.)
(b) In determining the aggregate sum of the taxable gifts for the “preceding calendar periods” (as defined in § 25.2502-1(c)(2)), the total of the amounts allowed as deductions for the specific exemption, under section 2521 (as in effect prior to its repeal by the Tax Reform Act of 1976) and the corresponding provisions of prior laws, shall not exceed $30,000. Thus, if the only prior gifts by a donor were made in 1940 and 1941 (at which time the specific exemption allowable was $40,000), and if in the donor's returns for those years the donor claimed deductions totaling $40,000 for the specific exemption and reported taxable gifts totaling $110,000, then in determining the aggregate sum of the taxable gifts for the preceding calendar periods, the deductions for the specific exemption cannot exceed $30,000, and the donor's taxable gifts for such periods will be $120,000 (instead of the $110,000 reported on the donor's returns). (The allowable deduction for the specific exemption was $50,000 for calendar years before 1936, $40,000 for calendar years 1936 through 1942, and $30,000 for 1943 through 1976.)
(c) If the donor and the donor's spouse consented to have gifts made to third parties considered as made one-half by each spouse, pursuant to the provisions of section 2513 or section 1000(f) of the Internal Revenue Code of 1939 (which corresponds to section 2513), these provisions shall be taken into account in determining the aggregate sum of the taxable gifts for the preceding calendar periods (under paragraph (a) of this section).
(d) If interpretations of the gift tax law in preceding calendar periods resulted in the erroneous inclusion of property for gift tax purposes that should have been excluded, or the erroneous exclusion of property that should have been included, adjustments must be made in order to arrive at the correct aggregate of taxable gifts for the preceding calendar periods (under paragraph (a) of this section). However, see section 1000 (e) and (g) of the 1939 Code relating to certain discretionary trusts and reciprocal trusts. However, see § 25.2504-2(b) regarding certain gifts made after August 5, 1997.
