Why check your withholding

There are several reasons to check your withholding:

• It can protect against having too little tax withheld and facing an unexpected tax bill or penalty at tax time next year.
• It can let you adjust your tax withheld up front, so you receive a bigger paycheck and smaller refund at tax time.

When to check your withholding

Check your tax withholding every year, especially:

When you have a major life change

• New job or other paid work
• Major income change
• Marriage
• Childbirth or adoption
• Home purchase

If you changed your tax withholding mid-year

• Check your tax withholding at year-end, and adjust as needed with a new W-4

If you have questions about your withholding, ask your employer or tax advisor.  Estimator Frequently Asked Questions
