I'm currently a Massachusetts resident. I plan to do some seasonal work in South Dakota, a non income tax state. I have not made any income in MA this year and do not plan to. I actually would like to establish residency in a new state. But my question is how do I handle my taxes next year? Do I still pay taxes to MA for work I did in SD? Do I even have to file MA state taxes if I didn't make any income in MA?
Since you are a Massachusetts resident you have to pay Massachusetts tax on all of your income, no matter where the income is from. So you will have to file a Massachusetts tax return for 2025 and report the income that you earned in South Dakota.
