what states require a state income tax return for federal tax exempt dividends.
I'm not sure what you mean. Are you asking if one has to file state tax returns in multiple states because you had some federal tax-exempt dividends for multiple states--even for states that had no other "state source income" or had no filing requirement otherwise? If you explain more about what is prompting your question and what you need to know, then hopefully someone familiar with state tax returns will be able to comment further.
If you're asking about the filing requirements of a specific state(s), please provide the state name(s.)
