Ways to check your withholding on IRS.gov

June 5, 2019

The best way to do a Paycheck Checkup is to use the Withholding Calculator. However, you may need to use Publication 505.

Withholding Calculator

  • The Withholding Calculator helps you check if you need to adjust your withholding.
  • Use the results from the calculator to complete Form W-4 and adjust withholding.
  • If you receive pension income, use the results to complete a Form W-4P (PDF), and give it to your payer.
  • You can use the Withholding Calculator to determine if you should pay estimated tax.

Publication 505

  • If you have a more complex situation, you may need to use the instructions in Publication 505.
  • This includes those who owe self-employment tax, the alternative minimum tax, tax on unearned income by dependents or receive non-wage income.
