Remember you must file according to your status on December 31, 2022. If you are divorced on that date, you must file single or head of household, even if you were married for most of the year.
Also, if you are still married on 12/31/22 but the divorce is final in 2023, be aware that the refund will go to the designated bank account. If that account is joint, and closed, the IRS will send a check in both your names that you probably will have great difficulty in cashing or depositing. You can include a form to split your refund between 2 bank accounts, if you have set up separate individual accounts by that time. Exactly how to split the refund should be part of your negotiations about division of money and property, you may want to consult a tax professional or your attorneys.
Lastly, you have the option now of changing your W-4 job withholding so you get more money in your paycheck and then owe tax with your return. Then you would negotiate how to pay the tax rather than negotiation how to split a refund.
