How do calculate or file for next years taxes as my wife passed away Feb 1, 2022?

Very sorry for your loss.    For tax year 2022 you will still be able to file a joint tax return.

 For the year --2022----that your spouse died, you can still file a joint return.  That way, you will get the married filing jointly standard deduction of $25,900 (+ $1400 for each spouse 65 or older) which will lower the amount of income you are taxed on.

In My Info, you will need to indicate that your spouse died. When her name is in My Info,  there is a screen early in the interview that asks "Do any of these apply to [name] ?’” where you will do that, and then a drop down will appear where you can enter the date she passed.

If you have qualified dependent children , you will be able to file as a qualified widower for the next two years after this tax return.  Post back if you need further help.
