I moved from MA to IL last year. I am a part year resident of MA and IL in 2024. How do I file state tax with Turbotax?

You just have to add Massachusetts and Illinois to your return.  You should have indicated in the Personal Info section that you moved.  For each state, you will allocate the income that you earned while you were living in each state.

Thanks for a quick response! Should I purchase 2 state filing? How much cost?

Yes, you have to complete two part-year state returns for 2024. For current pricing, please click here. For more information on filing a part-year resident return, please click here.
