You can order a transcript of your return. You also can get one by completing and sending us a Form 4506-T, Request for Transcript of Tax Return.

I don't want a transcript of my return. I want a copy. How can I get one?

I can't get a copy of my return from a tax preparer. How else can I get a copy of it?
You can get a copy of your return by completing and sending us a Form 4506, Request for Copy of Tax Return. We charge a fee for return requests.

What do I do if the information is wrong?
You don't have to amend your return when the information is wrong. Instead, contact whoever reported the wrong information and ask them to correct it. You don't need to contact us.

Should I contact you to correct wrong information?
You don't have to contact us to explain why the information is wrong. You don't have to reply to your notice.

I reported the information but I reported it incorrectly. Can I call you to correct my return?
We can accept your information over the phone for incorrectly reported information as long as the mistake did not increase or decrease your tax. You should file an amended return when the information was never reported or misreported in a way that had tax consequences.

The information is wrong because someone else is using my name and Social Security number. What can I do?
You can visit our Identity theft information to find out more about what you can do. You also should call us and let us know.

Why did it take you so long to contact me about this matter?
Our computer systems match the information you report on your tax return with information reported by employers, banks, businesses, and others. This matching takes several months to complete.
