Well-organized records make it easier to prepare a tax return and help provide answers if your return is selected for examination or if you receive an IRS notice.
You must keep records, such as receipts, canceled checks, and other documents that support an item of income, a deduction, or a credit appearing on a return as long as they may become material in the administration of any provision of the Internal Revenue Code, which generally will be until the period of limitations expires for that return:
3 years – For assessment of tax you owe, this period is generally 3 years from the date you filed the return. Returns filed before the due date are treated as filed on the due date.
No limit – There’s no period of limitations to assess tax when you file a fraudulent return or when you don’t file a return.
6 years – If you don’t report income that you should have reported, and it’s more than 25% of the gross income shown on the return, the time to assess tax is 6 years from the date you filed the return.
