Tax Withholding Calculator
The tax withholding calculator has been developed to assist you in determining the dollar amount of Federal and State of Iowa tax to be withheld from your monthly pension. It should be used in conjunction with the instructions provided on the Federal and Iowa W-4P forms. The amount withheld is an approximate amount and is not binding upon MFPRSI. The retirement system does not provide tax or withholding advice. In order to determine your appropriate withholding amount, you may wish to contact a tax advisor.
