Milwaukee County Pension Fund's Same Control Failure, Third Year

The Wisconsin Legislative Audit Bureau⧉, the state's nonpartisan auditor, released its 2025 financial audit of the Employees' Retirement System of the County of Milwaukee⧉ (ERS) on July 17, 2026.▸ The fund holds $1.9 billion for 12,335 county retirees, active employees, and beneficiaries. The audit's finding: for the third straight year, Retirement Plan Services (RPS) -- the two-person fiscal team inside Milwaukee County's Department of Human Resources that runs the fund's day-to-day accounting -- has failed to maintain an adequate system of internal control. In 2025, auditors found, the fiscal officer who holds full administrator rights to the fund's accounting system entered and approved 22 accounting entries that no one else reviewed.

The problem first surfaced in the 2023 audit⧉, the first ERS review conducted under 2023 Wisconsin Act 12, the law that restructured the fund's finances.▸ Auditors found the Fiscal Officer completed bank reconciliations, authorized disbursements from ERS bank accounts, and held administrator access to the accounting system all at once, with no one else reviewing the entries -- a gap traced to 2022 staff turnover that left one person handling most fiscal duties. RPS made some fixes, but the 2024 audit⧉ found essentially the same weakness again, and now the 2025 audit⧉ has found it a third time.

RPS switched to new accounting software in May 2025, in part to address the prior findings, but auditors discovered the software's design let the fiscal officer keep administrator rights -- meaning the same person could both add a vendor and approve it, both write an accounting entry and sign off on it.▸ Only 2 of RPS's 18 authorized positions handle fiscal work at all, about 11% of the office, the staffing constraint all three audits cite as the underlying cause.

RPS did not stay silent between audits.▸ In a January 5, 2026 letter⧉ to the state legislature's Joint Legislative Audit Committee, Director Erika Bronikowski reported that of six findings in the prior audit, RPS had fully resolved four and partially resolved the remaining two -- including the internal-control finding -- and wrote that RPS "anticipate[d] resolving this report's two findings in early 2026." The letter described a Comprehensive Risk Assessment already underway: the Pension Board had approved hiring a consultant in June 2025, proposals were due that January, and the assessment itself was expected to wrap up by the third quarter of 2026.

None of that held.▸ The July 2026 audit⧉ found RPS had to issue a second request for proposals in April 2026 after the first didn't produce what it needed, and now says the risk assessment itself "may be completed by the end of 2027." RPS's own corrective action plan, filed with this audit, sets a new anticipated completion date of June 30, 2027 -- with a status update due to the Joint Legislative Audit Committee by January 8, 2027. If that holds, a fourth consecutive annual audit, covering 2026, will come and go with the finding still open.

The fund's underlying finances are not the problem the auditors are flagging, and the numbers show why that distinction matters.▸ The ERS's net pension liability -- what the fund owes retirees beyond what it currently holds -- fell from $729.4 million at the end of 2023, the year the internal-control finding first appeared, to $560.0 million at the end of 2025, the year it was cited a third time, a decline of $169.4 million. Over the same span the fund's percentage funded rose from 70.1% to 76.7%, a 6.6 percentage-point gain, driven mainly by Milwaukee County's 2023 sales-tax increase⧉ dedicated to the fund and by investment returns. That tax generated $83.2 million for the ERS in 2025 alone, and the county separately carries $135.1 million in outstanding pension obligation bonds tied to the fund.

None of that money passes through the control gap the auditors found -- the finding is about whether RPS's own bookkeeping can be trusted, not about whether the fund has enough money.▸ But the auditors were direct about what an unreviewed accounting entry means in practice: an increased risk that misappropriation of ERS assets, or an inadvertent or intentional error in the fund's financial statements, would not be prevented or caught in a timely way. The audit did not find that any theft or material misstatement had occurred -- it found the fund lacked the internal check that would reliably catch one.

The ERS itself is a closing chapter: Milwaukee County stopped enrolling new members after December 31, 2024, so every employee hired since then joins the state's Wisconsin Retirement System instead.▸ RPS will keep administering benefits for the 12,335 people already in the ERS -- 7,559 already drawing benefits, 3,137 still working, and 1,639 vested but not yet collecting -- for decades to come, even as the county's own accounting workforce for the fund stays at two people. The Bureau's recommendation is specific: give the accounting system a separate administrator who isn't the fiscal officer, require an independent review of every entry that officer makes, and put a periodic internal-control check into the Pension Board's own charter. RPS's corrective action plan accepts all of it -- the disagreement here isn't over what needs to happen, it's over whether "anticipated" timelines from a two-person office keep holding up against a workload that hasn't grown to match them.
