Which U.S. tax form should you review? Select the facts that match your situation to see forms that may be connected to excluded presence days, wages, treaty claims, foreign-status certification, ITIN needs, Form 1042-S reporting or a nonresident return.
The second part of the tool decodes the purpose and main sections of common nonresident forms so similarly named documents are not treated as interchangeable.

A form is evidence, not the whole tax answer
Receiving a W-2, 1042-S or 1099 can help identify what was reported, but the document alone does not determine final tax residency, treaty eligibility or filing duty. Compare the form with your tax status, income type and current instructions.
Why several forms may appear together
A single year can involve more than one document. For example, wage withholding, treaty-exempt compensation, foreign-status certification and the year-end return can each use different forms. The finder explains the role of each form rather than choosing one form for every situation.
