Illinois Box 16
I moved from Illinois to Wyoming in March 2020. My employer did not update my location to be WY at the time. They've since, now provided me with a W2C & refunded me the amount through payroll that should not have been paid to Illinois.
My issue is the W2C is still showing full wages (matching box 1) for Illinois in Box 16 vs just wages earned from my time in IL (Jan-March). My accountant is saying only wages earned in IL should be shown in box 16 and since WY has no income tax, there will be no line for WY. The payroll company is telling my employer that Illinois reports ALL wages regardless.
How do I file?
