But even though we have no vehicle tax, we have high property taxes in Wisconsin, and a new lawsuit filed by several school districts and education organizations helps to explain why. Public school districts have less state assistance to operate their schools, while local revenues (property taxes, mostly) have had to make up some of the difference In the 1999–2000 school year, public school district revenue broke down as 53.7% state, 41.6% local, and 4.7% federal. By 2023–24, the most recent year of available data, that mix had shifted to 45% state, 43% local, and 12% federal. The state share notably declined, beginning in earnest after the 2008 recession, and has never fully recovered. Meanwhile, the local revenue share has increased, and the federal contribution has nearly tripled, driven largely by temporary pandemic relief funding.In the 2 years since then, COVID-era federal assistance has declined significantly, but General Aids from the state were not increased for 2025-26 by the WisGOP Legislature, resulting in over 70% of Wisconsin districts having less state aid this year vs 2024-25. As a result, even more of K-12’s costs are going onto the property tax. The lawsuit also mentions two other reasons that Wisconsinites are paying higher property taxes for K-12 schools.
Had revenue limits kept pace with inflation since the 2009–10 school year, today school districts would receive an additional $3,380 in revenue per-pupil. Making matters worse, the Legislature has placed a significant additional strain on public education by creating and greatly expanding a competing system of largely unregulated and unaccountable voucher programs for private schools (“voucher schools”). These schools have expanded from educating 341 students in 1990 to over 59,000 students in the 2025–26 school year.The insufficient revenue limits have led schools to go to referendum to exceed those revenue limits in order to keep operating at the same (or even reduced) level of services. And outside of Milwaukee, school vouchers for private schools are funded by taking away funds from the public school district that the child lives in. Even if the child never attended a day of public school in the district. That’s $394 million being reduced from K-12 public schools to pay for these voucher programs, and also results in up to $394 million in additional property taxes to make up the difference. Which is why I think this question in the latest Marquette Law School Poll of Wisconsinites is kind of BS. This is a false choice, because the correct answer is “BOTH”. It’s wrong to say that the only way we have to raise funding for our community schools is through property taxes. If we added state aids, we could have added resources for the schools without having to raise property taxes. And even if we don’t outright ban vouchers (we’ll file that idea away for the future), there is no reason that we need to be forcing property tax increases as a result of that program. Make the voucher program fully state funded, and stop penalizing home owners when we give money to parents so their kids can separate themselves from the schools in their community. Based on what the Legislative Fiscal Bureau estimated earlier this month, making the state pay for all $394 million of the costs of vouchers would entirely cover Governor Evers' veto-based increase of $325 per pupil for Wisconsin school districts, and allow for $140 million in property tax relief on top of that. Seems like a win-win to me! Given that state aid to schools are the largest cost of state government, a lot of other areas of the state budget are at least indirectly affected by what happens with how we choose to fund K-12 education. But given that we will have a new Governor, new Assembly Speaker, and both houses of the Legislature up for grabs with fair maps for November, it sure seems like it's a great time to talk about how we can change from a status quo System that isn't working for either public schools or property taxpayers.
