New ETF Tax Withholding Calculator

The Department’s newest online calculator helps retirees determine the effect of their Wisconsin and federal income tax withholding elections on their monthly Wisconsin Retirement System (WRS) annuity payments. Calculator users enter their own data, such as monthly gross income, marital status and exemptions to do their own calculation. To change tax withholding amounts, retirees simply print the results of their calculation and mail it to the Department of Employee Trust Funds or call to change it over the phone. Go to the Income Tax Withholding Calculator.
