The federal tax tables have changed for 2017. This means some Wisconsin Retirement System retirees may see an adjustment to their federal tax deductions beginning with the February 1, 2017 payment.
Any member whose monthly payment has changed as a result of the new tax table will receive an annuity mailing statement from ETF reflecting the new withholding amount. To adjust your federal or state tax withholding, submit an Income Tax Withholding Election Change (ET-4310) form.
Before making any changes, you may want to use ETF’s online tax withholding calculator to help you determine the impact of income tax withholding elections on your monthly annuity payments.
