Why am I getting less back from Wisconsin for 2021 when I made about the same in 2020? Only difference is I changed jobs?

No one else can see your returns.    Compare your 2020 and 2021 W-2's to each other and see how much tax you had withheld for state tax ----look at boxes 16 and 17 of each one.   And print your 2020 and 2021 state returns and compare them side by side to see what is different.

There could be SO MANY reasons-

You earned fewer tax credits,

You had less tax withheld

You have less deductions

You can look at your 1040 lines 15 and 16 and compare that to your 2020 return. 

Line 15 shows your taxable income and Line 16 shows your tax liability. 

Those two numbers should give you a better idea of how your tax situation changed from last year.
