About Fill Out Form W-4 Online

What Form W-4 does

Your employer uses Form W-4 to work out how much federal income tax to withhold from each paycheck. You fill in your filing status, and optionally adjust for multiple jobs, dependents, other income, or deductions. Most new hires only need Steps 1 and 5; the other steps are for people who want to fine-tune their withholding.

Hand it over without printing

Many employers send the W-4 as a PDF attachment during onboarding. Instead of printing, filling by hand, and scanning, type your answers into RevivePDF, add your signature, and send back a clean PDF.
