Getting an ITIN via W7 for royalities?
Hey y'all, I (German tax resident, no US residency, greencard, citizenshop) received royalties from books sold in the US in 2025. I can apparently claim treaty benefits and reduce the tax withholdings in the US from 30% to 0%. I didn't do that for 2025 and now would like to get my overpaid money back. I filed a W7 to get an ITIN and attached Amazon's 1042-S.
Checkbox a and h, referencing Article 12 (Royalties) under Exception 1 referencing the instruction sheet.
I just received a rejection letter stating:
"We rejected your ITIN application because the supporting documents you sent don't support the exception to filling a U.S. tax return that you claimed."
The hotline is overloaded and my call automatically rejected. What do I need to file to get my ITIN?
