ShouldI keep my old tax returns? If so, for how long?
. Yes, you should keep your old tax returns for at least 7 years. When a return contains information pertaining to the basis of property owned, it should be kept until that property is sold. If you do throw out an old return you may fill out IRS Form 4506, Request for Copy of Tax Return, and send it to the IRS Service Center where you filed your return.
