How do I correct a mistake after filing?
In most cases you file an amended return using Form 1040-X. We review the original return first to confirm what needs to change and prepare the correction.

Made a mistake on your return? It can be fixed.
A mistake on a filed return is correctable, and fixing it properly is usually simpler than people fear.
Prepared by real tax specialists — with Enrolled Agent or CPA review when your return calls for it.
If you've already filed and then realized something was off, like missed income, a forgotten form, or a wrong number, you generally fix it by filing an amended return on Form 1040-X.
Amending lets you correct what was reported rather than leaving an error in place. If the fix means a refund is owed to you, there's generally a three-year window to claim it, so it's worth not putting off.
We start by reviewing the original return to understand exactly what changed and whether an amendment is even necessary, since some minor items the IRS adjusts on its own.

FAQ
Frequently asked questions
Is there a deadline to fix my return?
If the correction results in a refund, there's generally a three-year window to claim it by amending. It's best not to wait, since the window does close.
Will amending trigger an audit?
Filing an accurate amended return is a normal process and is how errors are meant to be corrected. We make sure the change is documented and reported correctly.
