Why was my state income tax amount wasn’t what it was supposed to be

[ThomasM125]

I think you mean your state refund amount was less than what you were expecting because it was less than last year's state refund? If so, you need to compare your return line by line with last years' to see what changed. Often, the tax withheld as reported in line 17 on your W-2 will be less than in the previous year. That means you may have made the same amount of money but less tax was paid in, so you get less back.
