Finishing the Return

Finishing Form 1040-NR

Identifying Your Site

Some taxpayers complete the taxpayer identification section and ask for your help on the other parts of the return. You can use the form they started, but be sure to complete the Paid Preparer Use Only section to properly identify your site information. This includes your: Site Name, Site Address, Phone Number, and Site Identification Number (SIDN) which is placed within the PTIN box. This ensures your site gets the appropriate credit for completing the return (QSR #8).
