Monthly Federal Tax Withholding Calculator

Use this calculator to estimate how much federal income tax will be withheld from your gross monthly SERS pension check. SERS has updated the calculator’s program to recognize the recent changes to the federal tax code.

This Monthly Federal Tax Withholding Calculator is intended to be used as a tool to estimate your own federal tax withholding. All data presented on this page is subject to audit, verification, and recomputation, and is provided as a convenience to you.

Calculations are based on rates effective January 1, 2014.

If you are married but would like to withhold at the higher single rate, please refer to the calculations for the single filer in the table above. 

If you would like to make a change to your current withholding, please complete a new W-4P and send it to your Regional Counseling Center.
