Get your taxes done using TurboTax

If you change your W-4 to have lots extra taken out, you need to remember to change it again January 1 so you don't have that excess withholding continue into 2024.

 

Instead, I suggest changing your W-4 to be whatever is appropriate for your new situation, then make a separate estimated tax payment of whatever you think you will owe, at www.irs.gov/payments.  Be sure to select "2023 estimated payment" as the reason.  The payment should be made before January 15.
