But let's say you have $1,000 worth of mutual fund shares that you bought more than a year ago for $500. If you sell the shares, you'll owe $75 in tax on the profit, even at the preferential 15% capital-gains rate. But if you donate the shares, the charity gets the full $1,000 (it doesn't have to pay tax on the profit when it sells), you avoid the $75 tax bill, and you still get to deduct the full grand. It's a win-win-win situation.
This gifting strategy does not work for investments that have lost value. For example, if a stock that you bought for $1,000 is now worth only $400 and you donate it to a charity, your deduction will be limited to the current $400 value. At that point, you would be better off selling the stock, making a tax-deductible contribution of $400 in cash to the charity and claiming a $600 capital loss. You can use your capital losses to offset your capital gains, and after that, you can use up to $3,000 of capital losses to offset ordinary income. Any excess losses can be carried forward to use in future years.
Giving appreciated securities sounds like a maneuver for fat cats, but it can pay off for philanthropists of more modest means, too. The charity you plan to help should be more than willing to fill in the details. Time is running out, though, and it will take a little longer than writing a check. The transfer of ownership has to be completed by December 31 to lock in the deduction for your 2013 return.
