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. 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.
There's no period of limitations to assess tax when you file a fraudulent return or when you don't file a return. 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.
For filing a claim for credit or refund, the period to make the claim generally is 3 years from the date you filed the original return (or the due date for filing the return if you filed the return before that date), or 2 years from the date the tax was paid, whichever is later. For filing a claim for an overpayment resulting from a bad debt deduction or a loss from worthless securities, the time to make the claim is 7 years from when the return was due.
You should keep records of your own and your family members' health care insurance coverage, including records of employer-provided coverage or premiums paid and type of coverage for private coverage, so you can show that you and your family members had and maintained required minimum essential coverage. If you're claiming the premium tax credit, you'll need information about any advance credit payments you received through the Health Insurance Marketplace, the premiums you paid, and the type of coverage you obtained at the Marketplace. If you or any of your family members are exempt from minimum essential coverage, you should retain certificates of exemption you may receive from the Marketplace or any other documentation to support an exemption claimed on your tax return.
If you have employees, you must keep all your employment tax records for at least 4 years after the tax becomes due or is paid, whichever is later. For more information, see Publication 15, (Circular E), Employer's Tax Guide.
If you're in business, there's no particular method of bookkeeping you must use. However, you must use a method that clearly and accurately reflects your gross income and expenses. The records should substantiate both your income and expenses. Publication 583, Starting a Business and Keeping Records, and Publication 463, Travel, Entertainment, Gift, and Car Expenses, provide additional information on required documentation for taxpayers with business expenses. Also, see our Recordkeeping page for more information. Publication 17, Your Federal Income Tax for Individuals, provides more information on recordkeeping requirements for individuals.
