W-4 Withholding Tax Calculator

You should try to have your withholding match your actual tax liability. If not enough tax is withheld, you will owe tax at the end of the year and may have to pay interest and a penalty. If too much tax is withheld, you will lose the use of that money until you get your refund.

Always check your withholding with this tool if there are personal or financial changes in your life that might change your tax liability. For a recommendation on your withholding, please complete the information below.

General Information

If your income and tax situation are similar to last year, enter your tax for the prior year. This can be found on your prior year tax return as follows:

  • Form 1040, line 63
  • Form 1040A, line 39
  • Form 1040EZ, line 12

Note: For wages, this information usually can be found on your last and most recent paystub(s). For self-employment, this will be your estimated tax payments made to date.
