Under Act 12, the City of Milwaukee was permitted to impose a sales and use tax of 2.0 percent and use the revenue to fund employer contributions to the Retirement System. Act 12 had other requirements, including closing the plan to new employees hired after December 31, 2023, and prohibiting increases or enhancements to Retirement System benefits for employees remaining in the Retirement System after December 31, 2023, except those required for compliance with federal law.
The City of Milwaukee reported $200.6 million as revenue for calendar year 2024 from the 2.0 percent sales and use tax. Each year, an amount up to 90 percent of the revenues collected in the first full year in which the tax was imposed may be used to fund certain components of the employer contribution amount. The maximum amount of the tax that can be used to fund employer contributions in any one year is $180.6 million. The actuary calculated that $137.8 million and $141.3 million of the employer contribution amount for calendar year 2024 and calendar year 2025, respectively, was eligible to be paid from the sales and use tax, based upon the requirements of Act 12.
