It depends but if you will not be able
to "cancel" an accepted US income tax return if it was efiled.
If you are a
nonresident alien and should have filed a 1040NR, then you will need to file an
amended return (Form 1040X).
Here are the steps to file an amended return when you
filed a 1040 but should have filed a 1040NR:
- Download a copy of both the Form 1040NR (which is not supported by TurboTax) and Form 1040X
- On page one of 1040X, just
enter your name, current address and your social security number (SSN) or
IRS individual taxpayer identification number (ITIN) but no other
information
- On page two of 1040X, do not
complete Parts I or II but in Part III (the explanation section), enter
your reason for filing an amended tax return (such as "filed Form
1040 when I needed to file Form 1040NR.)
- Complete your Form 1040NR and
write "AMENDED" at the top of page one
- Attach a copy of both your
1040NR and your 1040 (as filed) to the back of the 1040X.
- Mail the all copies to the
IRS.
