A cash gift entitles you to the most generous federal income tax charitable deduction—up to 60 percent of your adjusted gross income. If all deductible gifts within a given year exceed the 60-percent limit, the excess amount may be carried over as a deduction for up to five years.

We mail tax receipts for all gifts of $10 and above. However, if you give online, we will only mail tax receipts at your request—but we will e-mail a confirmation to you.
