Not usually. Most (if not all states) consider interest and other investment/ unearned income to be allocable to your resident state. However, there could be an exception if the interest is related to a business which operates in your nonresident state.
If you are asked to allocate income to the nonresident state, do not allocate the interest unless there is something special about the interest. If there is, you will need to inform us of the state and situation in further detail so we can pass along targeted guidance.
