Can i amend a tax return from 5 years ago

Question About Amending a Late Tax Return

I read that you cannot amend tax returns after three years.

I recently filed a return from six years ago, but after filing, I remembered that I paid estimated taxes in 2016, which I didn’t include in my return. Can I amend it now to include those estimated payments?

Part of the reason I didn’t file back then was because I thought I didn’t owe anything, but I just recalled that I had already made estimated payments. Any guidance on this would be appreciated.

Yes, you can amend a tax return from six years ago to add in estimated tax payments you forgot to include. You’ll need to file Form 1040-X to make the changes. Normally, you have up to three years from the original filing deadline to do this, so you’re still within that window. It’s a good idea to double-check everything with a tax professional or use tax software to ensure it’s done correctly.

Amended Form 1040, 1040-SR, 1040-NR, or 1040-SS/PR returns that are older than the current or previous two tax periods cannot be filed electronically. For those earlier tax years, amended returns must be submitted on paper.
