IRS withholding calculator

IRS logo graphic with blue IRS letteringAre you or your employees withholding too much federal income tax? Or not enough?

The IRS Withholding Calculator can help you or your employees fill out a new Form W-4, required every time the amount withheld is changed.

The calculator can also benefit anyone with concurrent jobs, couples who are both employed, those entitled to file as Head of Household and those with several children eligible for the Child Tax Credit.

Before you use the calculator, the IRS recommends you:

  • Have your most recent pay stub on hand.
  • Have your most recent income tax return.
  • Estimate values only if you must, remembering that the results will only be as accurate as the input.
