To determine the permissibility and the amount of the deduction for the contributed portion, the value of the contributed portion must be reduced by any gain that would not have been realized as long-term capital gain had the contributed portion been sold, taking into account the basis allocated to it.2 If the sale of the contributed portion by the donor would have resulted in long-term capital gain (see example 2, below), no reduction is required unless the gift is tangible personal property and the use of the gift will be unrelated to the function of the charity.3
After any such reduction required by IRC Section 170(e)(1) has been made, the remaining amount of the contribution is the allowable deduction.
The taxpayer’s adjusted basis in the property is then allocated to each portion in these proportions.4 It is allocated between the portions contributed and sold, based on their relative proportions of the property’s fair market value.5 Gain is recognized on the sale portion to the extent the amount realized exceeds the allocated basis. However, no loss is recognized if the sale amount is less than the allocated basis of the sold portion.6 The amount of the deduction for the contributed portion is determined as if property having the allocated basis and allocated fair market value were given.
