How do I change my federal withholding from my paycheck

The IRS encourages everyone to use the Withholding Calculator to perform a quick “paycheck checkup.”  This is even more important this year because of recent changes to the tax law for 2018.

To Change Your Withholding:

Use your results from this Calculator to help you complete a new Form W-4, Employee's Withholding Allowance Certificate, and submit the completed Form to your employer as soon as possible. Withholding takes place throughout the year, so it’s better to take this step as soon as possible.
