Get your taxes done using TurboTax

TurboTax’s free W-4 Withholding Calculator will figure your estimated refund or amount due and allow you to make adjustments.

Best of all, the calculator will show you exactly what numbers to fill in on Form W-4.

The slider allows you to adjust your results. In this example, the taxpayer decided to withhold an additional $25 per weekly paycheck to get a bigger refund.

TurboTax shows the paycheck impact, the projected refund, and — on the right side — the numbers to put on your W-4. If you’ve already filed a W-4, you can file a new one at anytime to change your withholding.
