I do not. Look in your area for a thing called a VITA tax site. Usually through the United Way. Free tax prep if your income is at least reasonable.

If they don’t withhold any state taxes you don’t really need a corrected w2. I would think.

You only need to show investment income if you made taxable income while in the state.

You need to pay the state taxes for money earned while you were a resident in that state. The best way to do this is to contact your HR department and ask for a corrected W-2 (W-2C). Some companies can be pain’s getting this done but it will be the best because then your taxes and the company’s payroll submissions will match. If they don’t do it, you don’t get out of jail free. You still need to report correctly on your taxes the income you earned in each state.
