After filing a tax return, you may have questions. 1. Where’s my refund? Go to irs.gov and click on “Refund Status” to find out. 2. How long must I save tax records? You should generally save them for 3 years after filing (although keep the actual returns indefinitely). But there are exceptions to this general rule. 3. If I forgot something on my return, can I still claim a refund? You can generally file an amended return to claim a refund within 3 years after the date you filed the original return or 2 years of the date you paid the tax, whichever is later.
