Recordkeeping. For any contribution made in cash, regardless of the amount, you must maintain as a record of the contribution a bank record (such as a canceled check or credit card statement) or a written record from the charity. The written record must include the name of the charity, date, and amount of the contribution. If you made contributions through payroll deduction, see Pub. 526 for information on the records you must keep. Do not attach the record to your tax return. Instead, keep it with your other tax records.
