Michigan property tax bills to increase in 2023, thanks to inflation

Every year, Michigan homeowners get a heads-up on how much their property taxes could be going up. And this year, we're getting hit by warnings that inflation will send taxable home values soaring by 5% on 2023 tax bills — the biggest increase in 28 years.

If you bought a home last year — or took on a big construction project to add on a bedroom — your taxable value likely would be going up more than 5%. But make no mistake, high inflation is going to hit property taxes in Michigan even if you just sat in your house and did nothing but order pizza and binge-watch "The Office."

Things could have been worse. Michigan homeowners would have been looking at a 7.9% hike based on the actual change in red-hot inflation. But Michigan law puts a 5% cap in place.

Homeowners will experience this bigger-than-normal increase when their summer property tax bills arrive in July. And yes, we're going to need to prepare for another big hike — possibly another 5% round — in property taxes next year too, thanks to persistently stubborn inflation.

How inflation hits property taxes

High inflation contributed to a rise in property tax values for 2022, too.

The inflation rate multiplier for 2022's property taxes in Michigan hit 3.3% — the highest it had been in several years. The multiplier had peaked at 4.4% in 2009. And it was 3.7% in 2007 and 3.3% in 2006, but it was significantly lower for about 12 years before rising in 2022.

When inflation was low in recent years, Michigan homeowners might have been looking at an annual hike of 1% or 2% in the taxable value.

It says: 'This is not a tax bill'

Many homeowners have no idea how inflation comes into play regarding property taxes or even how the complex Michigan property tax system works. And they might not be prepared for paying more in taxes.

Unfortunately, many tend to ignore a standard one-page notice printed on white paper that's sent out early each year. It's called a "Notice of assessment, taxable valuation and property classification."

The right-hand corner on the top of that notice states in bold, black letters: "This not a tax bill."

So, if it's not a tax bill, well, you might skim it, toss it in a drawer and easily forget about it. But you shouldn't.

Always read your tax assessment notice

"Rule No. 1: Always look at your assessment notice every year. Do not ignore it," said Patrick Anderson, a longtime Michigan economist and CEO of the boutique Anderson Economic Group consulting firm in East Lansing.

"The fact that it says across the top 'This is not a tax bill,'" Anderson said, "does not mean that it doesn't directly lead to not only one tax bill but a whole series of tax bills."
