New Job and the IRS
When you start a new job, you must fill out a Form W-4, Employee’s Withholding Allowance Certificate and give it to your employer.
Your employer will use the form to figure the amount of federal income tax to withhold from your pay.
Use the IRS Withholding Calculator on IRS.gov to help you fill out the form.
This tool is easy to use and it’s available 24/7.
