How do I correctly file state taxes when I lived and worked in 3 states in 2024?

You will file part-year tax returns for the three states that you lived in for 2024. TurboTax will guide you through allocating your income when you move from one state to another during the year. When you are preparing your part-year resident tax returns, you will allocate your income to the state that you were a resident of when you received it. 

If you've already entered your personal information, review your entries to help ensure that TurboTax will help you create the correct part-year tax returns. 

1. Open TurboTax and select My Info
2. A Personal profile summary screen will pop up
3. Select Revisit by your address
4. Scroll through the screens to help ensure that you have the correct answers for your state of residence and choose that you lived in another state. A new section will appear asking for your previous state of residence. Select the other state that you live in.
5. Scroll down to Other State Income and select Edit
6. Check your answer for Did you make money in any other states? Answer the questions and select Continue.

After you complete your federal tax return and you move to the State Taxes sections, your part-year state returns will be listed.  Prepare the state that you moved from first and prepare the state that you currently live in last.
