As said previously, In particular, Question #10 is of concern. you know India/USA have a tax treaty, but the issue is under what article the withholding is defined, and what explanation you can offer for eligibility under the treaty article;u need to go and check article appropriate for your situation . for instance in case of Canada,say you are a Canadian citizen, then the treaty entitles a Canadian citizen to withholding rates of
15% on dividends (Article X)
10% on interest (Article XI)
0% on capital gains (Article XIII)
so yopu, as a Canadian citizen is entitled to those rates because, under the definitions made in Articles III and IV, you are a person resident in Canada.
on line 10, the line must be used only if you are claiming treaty benefits requiring that you meet conditions not covered by the representations you make in lines 9a through 9e. I mean these lines are used if India has a tax treaty with the US that limits the tax rate on your IRA distributions income.So unless India has a treaty with the US,so filling out lines 9a-9e in Part II may be sufficient.
