You cannot change your W-4 retroactively. The number of allowances is used to determine the amount of federal tax to be withheld from your paychecks. If you overstated your allowances, you may have too little tax withheld and may have some tax due (and possibly a penalty for under-withholding).

To change your allowances, you need to submit as soon as possible a new W-4 form to your employer.

@Leslyxxxlove7You cannot change it after the fact. The amount of tax you had withheld is what it is at this point, so you may get only a small refund or even owe since you did not have enough withheld from your pay. All you can do is enter the W-2 exactly as it appears and see how your return comes out.

Going forward, you can change the W-4 you give to your employer and have more tax withheld for 2022 now.

You must enter the information as it appears on your W4. If your W4 is wrong, you will need to contact your employer and update your information with them.

@Winton58 If you filled out your W-4 for the employer incorrectly last year and did not have enough tax withheld , there is nothing to be done about that now. You have to enter your W-2 just as it appears; if you did not have enough tax withheld your 2022 refund or tax due is now going to be affected by that. Going forward, you can complete a new W-4 for your employer and have more withheld for tax year 2023.
