Even a small donation can qualify for a deduction.

Once you file, keep your return and all supporting documents for at least three years, in case the IRS has questions.
Store a PDF copy of your e‑file confirmation and any receipts you entered.
If you plan to claim a deduction or credit that requires documentation, keep those records in a dedicated folder.
