How long should I keep my tax documents before discarding them? Should I just keep them forever?

Keep records for 3 years from the date you filed your original return or 2 years from the date you paid the tax, whichever is later, if you file a claim for credit or refund after you file your return. You might want to keep documentation of stock purchases until you sell them.
