Tax Withholding Calculator

To get a larger refund, increase your additional withholding on line 4(c) of Form W-4. However, a large refund means you've been giving the government an interest-free loan.

Ideally, your withholding should be close to your actual tax liability — resulting in a small refund or small amount owed. This keeps more money in your pocket throughout the year.

Update your W-4 after major life changes: marriage, divorce, new child, buying a home, significant income change, or if your last refund was too large or you owed too much.
