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.
