I worked in one state for the first part of the year and then I moved to another. To which states do I need to send a state tax return?

A state tax return generally should be filed for states where income has been generated.

Example: A taxpayer works in California, New York, Nevada and Florida during the course of the year. The taxpayer needs to file only a California and New York tax return because Florida and Nevada do not have an individual income tax therefore no tax return is required in those states.
