File a new 2025 IRS Form W-4 if tax status for 2025 is exempt

If you wish to claim an exempt withholding status for federal tax purposes in 2025, you must file an Internal Revenue Service Form W-4. This applies whether you claimed exempt withholding status in 2024 or not.

This form is used to designate how much tax we withhold and remit to the IRS as advance tax payments throughout the year.

The exemption from 2024 federal tax withholding certificate expires Feb. 15, 2025.

If you claimed exempt in 2024, and we do not receive a new signed IRS Form W-4 by Feb. 18, 2025, your federal income tax withholding status will be changed to single/no exemption for the pay period ending March 8, 2025.

We cannot apply retroactive withholding adjustments if you submit the IRS Form W-4 claiming exempt status late. Per IRS guidance, if they receive the form after the deadline, they will apply the exempt status to future wages only.

You must send the form to us by one of these ways:

• Fax at 816-823-5435
• Mail at Attn: Customer Service, 2300 Main Street 2NW, Kansas City, MO 64108
• Email at KC-Payroll.Finance@gsa.gov
