As your marriage ends and your new life begins, there are several steps you should take to tie up the loose ends of your former life. Failing to deal with these loose ends won’t make things any easier later, and can lead to unintended consequences.
Update your W-4
Employers rely on the information you provide them in your W-4 form to determine how much income tax to withhold. Once your marital status, and possibly your child custody status has changed, make certain to change your W-4 to reflect these changes. Failure to do so may result in your employer withholding too much, or not enough in taxes. This could lead to unpleasant consequences later.
