How long should you keep your tax record

The IRS Tax return proofs as well as forms, receipts, canceled checks, and other documents could be needed later. While the IRS may be undergoing changes, the tax agency generally has three years after the due date of your return (or the date you file it, if later) to kick off an audit — that hasn't changed.
Plus, some documents may be kept even longer. For instance, it might be wise to save W-2 forms until you start receiving Social Security benefits so you can verify your income if there's a problem.
Here's some information on how long you should keep certain common tax records and documents.
