Hi, I am a F1 student and I am currently a non-resident alien living in AZ. I recently won a non-compensatory fellowship and was asked by the funding agency to fill the W-8BEN form. I am a citizen of India and I am eligible for some tax exempts under the US-India Income Tax Treaty Article 21. However, I am not sure what to fill in line 10 of the W-8BEN form, which asks for the rate of withholding and the type of income. Can someone please help? Thank you.
