I am a tax preparer that is looking for a software that supports 1040nr,
There are a few customers asking me if I can do a return for a non resident allien.
Can I get help on this one? Is there a software for preparers?
Thanks

Most software do not do nonresident tax return. It must be paper return and can not be efiled. Your U.S. Tax Return: U.S. Tax Filing Requirements for Non-Residents

Try these ones:

2. http://www.visataxes.com/form1040nrez_home.php

Most of them only offer the simpler form (1040NR-EZ), but sometimes that's enough.

The Form 1040NR is a VERY complex form, and writing software for it would be a major undertaking with major costs.

I believe the reason there is no software is that the market is not large enough to justify the cost of developing and maintaining the software.
