Limitation on itemized deductions. Starting with the 2013 tax year, the so-called Pease limitation on itemized deductions (named for the congressman who first introduced it) applies to charitable deductions. For 2017 most itemized deductions, including charitable deductions, are reduced by 3% of AGI over $261,500 for single filers and $313,800 for joint filers (up to a maximum total of 80% of nonexempt itemized deductions). The limitation is indexed for inflation and changes each year.
The computation of this figure is too complicated to explain here. If your contribution deduction is more than 20% of your adjusted gross income, Publication 526, Charitable Contributions, has a good explanation of the limits and a worksheet you can use to figure the deduction limits.
