Additional exemptions for dependents

(a) Section 151(e) allows to a taxpayer an exemption for each dependent (as defined in section 152) whose gross income (as defined in section 61) for the calendar year in which the taxable year of the taxpayer begins is less than the amount provided in section 151(e)(1)(A) applicable to the taxable year of the taxpayer, or who is a child of the taxpayer and who—

(1) The taxable year of the taxpayer begins, or

(2) Is a student, as defined in paragraph (b) of § 1.151-3.

No exemption shall be allowed under section 151(e) for any dependent who has made a joint return with his spouse under section 6013 for the taxable year beginning in the calendar year in which the taxable year of the taxpayer begins. The amount provided in section 151(e)(1)(A) is $750 in the case of a taxable year beginning after December 31, 1972; $700 in the case of a taxable year beginning after December 31, 1971, and before January 1, 1973; $650 in the case of a taxable year beginning after December 31, 1970, and before January 1, 1972; $625 in the case of a taxable year beginning after December 31, 1969, and before January 1, 1971; and $600 in the case of a taxable year beginning before January 1, 1970. For special rules in the case of a taxpayer whose taxable year is a fiscal year ending after December 31, 1969, and beginning before January 1, 1973, see section 21(d) and the regulations thereunder.

(b) The only exemption allowed for a dependent of the taxpayer is that provided by section 151(e). The exemptions provided by section 151(c) (old-age exemptions) and section 151(d) (exemptions for the blind) are allowed only for the taxpayer or his spouse. For example, where a taxpayer provides the entire support for his father who meets all the requirements of a dependent, he is entitled to only one exemption for his father (section 151(e)), even though his father is over the age of 65.
