If you make a monetary donation of less than $250, you can prove your donation with a bank record or payroll deduction record if you don't have a receipt. The $250 limit applies to the amount of each contribution. For example, if you donate $100 every week to your temple using a chack, you can prove the deduction with canceled checks. However, if you make just one $300 cash donation, you can't claim the donation as a deduction without a receipt. Out-of-Pocket Expenses If you pay expenses out of your own pocket for the charity, you can include those contributions as part of your deduction.
Itemizing required. You can give thousands of dollars, but if you claim the standard deduction amount on your tax return, your charitable gifts will do you no tax good. You must itemize expenses on Schedule A to deduct charitable donations. The good thing about donations is that, in most cases, there is no limit on how much you can deduct.
