Made mistake filing tax ?

Let's be honest here. You didn't make a mistake. You lied deliberately - you say so yourself.

If you filed the return, no matter what day it is, no you can't just undo it, you have to amend to fix it.

But just saying you're a student doesn't give you anything extra back. It just makes the software ask some additional questions. If you put in amounts you claimed to have paid for education expenses, you have a problem and must amend. If the only thing you lied about was whether you were a student, your return is OK.

It's best to wait until you have received your refund to file your amended return. Once your refund is received, you know your original return has been processed. If you send in your amended return before you original return is processed, it can slow down the entire process while the IRS tries to reconcile two open returns.

No issue, that question is only used to determine educational credits and eligibility to be claimed as a dependent. You don't get extra money for being a student.

No need to amend.

Nahh... you planning on buying a house isn't going to set off their alarm bells. It is absolutely possible to be a student one year and a working adult the next year that has bought a house and is filing married filing jointly... because you have until December 31st to get married too.

Greater miracles have happened and the IRS won't question it.

Ammend now.

shouldnt have done that... now you wait.
