Paycheck tool

Understand your W-4.

A W-4 tells payroll how much federal tax to take from each paycheck. This version starts with normal questions, then tells you which parts of the form to review.

Before you start

This helper does not calculate your tax return. It helps you prepare before using the official IRS estimator or submitting a payroll change.

Use a recent paystub if you have one.
Use the IRS estimator if you have two jobs, a working spouse, side income, large deductions, or a mid-year change.
Do not enter sensitive information like a Social Security number here.
