(a) In general.

(1) In the case of a charitable contribution, not made by a transfer in trust, of any interest in property which consists of less than the donor's entire interest in such property, no deduction is allowed under section 170 for the value of such interest unless the interest is an interest described in paragraph (b) of this section. See section 170(f)(3)(A). For purposes of this section, a contribution of the right to use property which the donor owns, for example, a rent-free lease, shall be treated as a contribution of less than the taxpayer's entire interest in such property.

(2)

(i) A deduction is allowed without regard to this section for a contribution of a partial interest in property if such interest is the taxpayer's entire interest in the property, such as an income interest or a remainder interest. Thus, if securities are given to A for life, with the remainder over to B, and B makes a charitable contribution of his remainder interest to an organization described in section 170(c), a deduction is allowed under section 170 for the present value of B's remainder interest in the securities. If, however, the property in which such partial interest exists was divided in order to create such interest and thus avoid section 170(f)(3)(A), the deduction will not be allowed. Thus, for example, assume that a taxpayer desires to contribute to a charitable organization an income interest in property held by him, which is not of a type described in paragraph (b)(2) of this section. If the taxpayer transfers the remainder interest in such property to his son and immediately thereafter contributes the income interest to a charitable organization, no deduction shall be allowed under section 170 for the contribution of the taxpayer's entire interest consisting of the retained income interest. In further illustration, assume that a taxpayer desires to contribute to a charitable organization the reversionary interest in certain stocks and bonds held by him, which is not of a type described in paragraph (b)(2) of this section. If the taxpayer grants a life estate in such property to his son and immediately thereafter contributes the reversionary interest to a charitable organization, no deduction will be allowed under section 170 for the contribution of the taxpayer's entire interest consisting of the reversionary interest.

(ii) A deduction is allowed without regard to this section for a contribution of a partial interest in property if such contribution constitutes part of a charitable contribution not in trust in which all interests of the taxpayer in the property are given to a charitable organization described in section 170(c). Thus, if on March 1, 1971, an income interest in property is given not in trust to a church and the remainder interest in the property is given not in trust to an educational organization described in section 170(b)(1)(A), a deduction is allowed for the value of such property.

(3) A deduction shall not be disallowed under section 170(f)(3)(A) and this section merely because the interest which passes to, or is vested in, the charity may be defeated by the performance of some act or the happening of some event, if on the date of the gift it appears that the possibility that such act or event will occur is so remote as to be negligible. See paragraph (e) of §1.170A-1.

(b) Contributions of certain partial interests in property for which a deduction is allowed. A deduction is allowed under section 170 for a contribution not in trust of a partial interest which is less than the donor's entire interest in property and which qualifies under one of the following subparagraphs:

(1) Undivided portion of donor's entire interest.

(i) A deduction is allowed under section 170 for the value of a charitable contribution not in trust of an undivided portion of a donor's entire interest in property. An undivided portion of a donor's entire interest in property must consist of a fraction or percentage of each and every substantial interest or right owned by the donor in such property and must extend over the entire term of the donor's interest in such property and in other property into which such property is converted. For example, assuming that in 1967 B has been given a life estate in an office building for the life of A and that B has no other interest in the office building, B will be allowed a deduction under section 170 for his contribution in 1972 to charity of a one-half interest in such life estate in a transfer which is not made in trust. Such contribution by B will be considered a contribution of an undivided portion of the donor's entire interest in property. In further illustration, assuming that in 1968 C has been given the remainder interest in a trust created under the will of his father and C has no other interest in the trust, C will be allowed a deduction under section 170 for his contribution in 1972 to charity of a 20-percent interest in such remainder interest in a transfer which is not made in trust. Such contribution by C will be considered a contribution of an undivided portion of the donor's entire interest in property. If a taxpayer owns 100 acres of land and makes a contribution of 50 acres to a charitable organization, the charitable contribution is allowed as a deduction under section 170. A deduction is allowed under section 170 for a contribution of property to a charitable organization whereby such organization is given the right, as a tenant in common with the donor, to possession, dominion, and control of the property for a portion of each year appropriate to its interest in such property. However, for purposes of this subparagraph a charitable contribution in perpetuity of an interest in property not in trust where the donor transfers some specific rights and retains other substantial rights will not be considered a contribution of an undivided portion of the donor's entire interest in property to which section 170(f)(3)(A) does not apply. Thus, for example, a deduction is not allowable for the value of an immediate and perpetual gift not in trust of an interest in original historic motion picture films to a charitable organization where the donor retains the exclusive right to make reproductions of such films and to exploit such reproductions commercially.

(ii) With respect to contributions made on or before December 17, 1980, for purposes of this subparagraph a charitable contribution of an open space easement in gross in perpetuity shall be considered a contribution of an undivided portion of the donor's entire interest in property to which section 170(f)(3)(A) does not apply. For this purpose an easement in gross is a mere personal interest in, or right to use, the land of another; it is not supported by a dominant estate but is attached to, and vested in, the person to whom it is granted. Thus, for example, a deduction is allowed under section 170 for the value of a restrictive easement gratuitously conveyed to the United States in perpetuity whereby the donor agrees to certain restrictions on the use of his property, such as, restrictions on the type and height of buildings that may be erected, the removal of trees, the erection of utility lines, the dumping of trash, and the use of signs. For the deductibility of a qualified conservation contribution, see §1.170A-14.

(2) Partial interests in property which would be deductible in trust. A deduction is allowed under section 170 for the value of a charitable contribution not in trust of a partial interest in property which is less than the donor's entire interest in the property and which would be deductible under section 170(f)(2) and §1.170A-6 if such interest had been transferred in trust.

(3) Contribution of a remainder interest in a personal residence. A deduction is allowed under section 170 for the value of a charitable contribution not in trust of an irrevocable remainder interest in a personal residence which is not the donor's entire interest in such property. Thus, for example, if a taxpayer contributes not in trust to an organization described in section 170(c) a remainder interest in a personal residence and retains an estate in such property for life or for a term of years, a deduction is allowed under section 170 for the value of such remainder interest not transferred in trust. For purposes of section 170(f)(3)(B)(i) and this subparagraph, the term personal residence means any property used by the taxpayer as his personal residence even though it is not used as his principal residence. For example, the taxpayer's vacation home may be a personal residence for purposes of this subparagraph. The term personal residence also includes stock owned by a taxpayer as a tenant-stockholder in a cooperative housing corporation (as those terms are defined in section 216(b) (1) and (2)) if the dwelling which the taxpayer is entitled to occupy as such stockholder is used by him as his personal residence.

(4) Contribution of a remainder interest in a farm. A deduction is allowed under section 170 for the value of a charitable contribution not in trust of an irrevocable remainder interest in a farm which is not the donor's entire interest in such property. Thus, for example, if a taxpayer contributes not in trust to an organization described in section 170(c) a remainder interest in a farm and retains an estate in such farm for life or for a term of years, a deduction is allowed under section 170 for the value of such remainder interest not transferred in trust. For purposes of section 170(f)(3)(B)(i) and this subparagraph, the term farm means any land used by the taxpayer or his tenant for the production of crops, fruits, or other agricultural products or for the sustenance of livestock. The term livestock includes cattle, hogs, horses, mules, donkeys, sheep, goats, captive fur-bearing animals, chickens, turkeys, pigeons, and other poultry. A farm includes the improvements thereon.

(5) Qualified conservation contribution. A deduction is allowed under section 170 for the value of a qualified conservation contribution. For the definition of a qualified conservation contribution, see §1.170A-14.

(c) Valuation of a partial interest in property. Except as provided in §1.170A-14, the amount of the deduction under section 170 in the case of a charitable contribution of a partial interest in property to which paragraph (b) of this section applies is the fair market value of the partial interest at the time of the contribution. See §1.170A-1(c). The fair market value of such partial interest must be determined in accordance with §20.2031-7, of this chapter (Estate Tax Regulations), except that, in the case of a charitable contribution of a remainder interest in real property which is not transferred in trust, the fair market value of such interest must be determined in accordance with section 170(f)(4) and §1.170A-12. In the case of a charitable contribution of a remainder interest in the form of a remainder interest in a pooled income fund, a charitable remainder annuity trust, or a charitable remainder unitrust, the fair market value of the remainder interest must be determined as provided in paragraph (b)(2) of §1.170A-6. However, in some cases a reduction in the amount of a charitable contribution of the remainder interest may be required. See section 170(e) and paragraph (a) of §1.170A-4.

(d) Illustrations. The application of this section may be illustrated by the following examples:

(e) Effective date. This section applies only to contributions made after July 31, 1969. The deduction allowable under §1.170A-7(b)(1)(ii) shall be available only for contributions made on or before December 17, 1980. Except as otherwise provided in §1.170A-14(g)(4)(ii), the deduction allowable under §1.170A-7(b)(5) shall be available for contributions made on or after December 18, 1980.
