Capital gain property - property that would result in long-term capital gain if it
were sold at its FMV on the date it was contributed.
You usually may deduct gifts of capital gain property at
their FMV. However, you must reduce the FMV by the
amount of any appreciation if any of the following apply:
* The capital gain property is contributed to certain
private nonoperating foundations. This rule does not apply
to qualified appreciated stock.
* You choose the 50% of adjusted gross income limit instead of the special 30%
limit for capital gain property. (in other words if you use the 30% option you will need adjusted gross income of $550,000 to get the full deduction in the year of donation. if you use the 50% option, you only get a deduction for your basis in the stock.
