I'm not sure why 3/4 comments right now are talking about how the marriage applies for the whole year as long as you are married by 12/31, because it sounds like you know that.

As the only helpful comment from /u/SpiritualQuokka says, there are plenty of tax estimators out there, so you should really try a couple of those out to see how much you would benefit. A very simple look at the tax brackets for 2022 show you barely break into the 32% bracket as a single filer, but would barely make it into the 24% bracket if you were married. I plugged your numbers into this calc using MN for state tax.

Single:

180k = 57716

15k = 1525

Total = 59241

Married:

195k = 51659

So, getting married would save you about 6k in taxes.
