Attach To Form 1040, Form 1040nr, Or Form 1040x: Fill & Download for Free

You should amend your tax returns from 1040 to 1040NR using Form 1040X. The Form 1040X instructions has a section regarding nonresident alien returns. It says (emphasis added by me):Use Form 1040X to amend Form 1040NR or Form 1040NR-EZ. Also, use Form 1040X if you should have filed Form 1040 (or, for years before 2018, Form 1040, 1040A, or 1040EZ) instead of Form 1040NR or 1040NR-EZ, or vice versa.To amend Form 1040NR or 1040NR-EZ, or to file the correct return, do the following:Enter your name, current address, and social security number (SSN) or individual taxpayer identification number (ITIN) on the front of Form 1040X.Don’t enter any other information on page 1. Also, don’t complete Parts I or II on page 2 of Form 1040X.Enter in Part III the reason why you are filing Form 1040X.Complete a new or corrected return (Form 1040, Form 1040NR, etc.).Across the top of the new or corrected return, write "Amended."Attach the new or corrected return to the back of Form 1040X.Basically, to amend your return from 1040 to 1040NR, you would fill out only your name, address, SSN/ITIN on 1040X, skip Parts I and II, and enter the reason for amending in Part III of 1040X. Then you would attach a correctly filled-out 1040NR form, with “Amended” written on it, to the back of 1040X.

You should amend your taxes by filing Form 1040X. The Form 1040X instructions contains a section called “Resident and nonresident aliens” which contains instructions on what to do when you filed the wrong form:Use Form 1040X to amend Form 1040NR or Form 1040NR-EZ. Also, use Form 1040X if you should have filed Form 1040 (or, for years before 2018, Form 1040, 1040A, or 1040EZ) instead of Form 1040NR or 1040NR-EZ, or vice versa.To amend Form 1040NR or 1040NR-EZ, or to file the correct return, do the following:Enter your name, current address, and social security number (SSN) or individual taxpayer identification number (ITIN) on the front of Form 1040X.Don’t enter any other information on page 1.

If you filed a nonresident alien return in a previous year, there's a good chance that the IRS will review your return, and ask you to substantiate your residency status and filed a corrected return if you can't.You should correct your return once you determine that you filed incorrectly, regardless of whether or not you receive an IRS notice. The way that you do this is to file an amended return, Form 1040X, and:Enter only your name, address, and taxpayer ID number on Page 1 of the 1040X;Enter the reason why you are filing an incorrect return in Part III of the 1040X;Leave the remainder of Form 1040X blank;Attach a completed Form 1040NR to the back of the 1040X, printing “AMENDED” across the top.
