How Long You Should Keep Tax Records. To be on the safe side, keep your tax records for a minimum of three years or whenever the statute of limitations runs out for filing returns or refunds, whether youâre claiming personal deductions or keeping receipts for business expenses.
The IRS says you must keep your records as long as they may be needed to prove the income or deductions on a tax return. For example, determining gain or loss on a sale or disposal of an asset, you will need to substantiate the cost, so records and receipts related to that asset must be kept as long as asset is still in service and then add 3 years. The IRS says the length of time to retain business documents varies depending on how honest and how accurate your tax returns have been. If you file a fraudulent return, you must keep records indefinitely..
