There are four situations in which you will need to file taxes in more than one state. The first is if you generate income in two states, such as having two jobs or moving. The second circumstance is if you lived and worked in one state and then moved to another. Third, if you live in one state, such as Ohio, and work in another state, such as Kentucky. The last situation in which you will have to pay taxes to another state is if you own property that generates income in that state, such as rental property.
