How do I know how much income belongs to a state if I'm a part-year resident of the state?

Part-year resident income is usually all income you received, regardless of its source, during the part of the year you were a resident of the state. It also includes any income earned from sources in the state before or after your period of residency.

We've already calculated the total amount of your income in each category, so you just need to tell us how much of your total income applies to the state.

Here are a few examples. For state-specific tax treatment, see any additional help on this page or reference the state tax instructions.
