Any employee can change their withholding allowances by submitting a new federalW-4 and state forms (if needed) to their employer.
The amount of taxes an employer withholds from each paycheck is dependent on the number of allowances/deductions the employee claimed on the W-4 form.
States may also have a W-4 equivalent. Employees can change the withholding allowances for their states as well. Not sure if your state has its version of a W-4? The Bureau of Labor Statistics has a list of state withholding forms.
As a reminder, getting your withholding allowance number correct is important. If you withhold too little, you’ll likely owe taxes when you file. If you withhold too much, then you’ll get a refund.
When should I change my withholding allowances?
People typically change their withholding allowances when a life event may change their tax status or deductions. Such qualifying life events may include:
Getting married;
Having a child;
Taking in an elderly parent as a dependant;
Getting a pay raise or job that pays you more; and
Getting a second job that pays you more.
