Michigan property tax bills will go up again significantly in 2024, thanks to inflation

Most Michigan homeowners will soon face bigger property tax bills now that a back-to-back 5% hike is set to hit taxable home values in 2024. And yes, you can blame higher inflation for three years of out-of-the ordinary jumps in property taxes.

The latest news is found in a too-often-ignored piece of paper that landed in mailboxes over the past few weeks. The top of that notice states in bold, black letters: "This not a tax bill."

The tax bill arrives in July. On the notice, though, you'll see a dollar amount for the change in the taxable value of your home listed on Line 1 of that notice. Your actual property taxes reflect that taxable value as well as the millage rates in your community.

Increases in the taxable value mean you will pay more in property taxes ahead. A box above Line 1 for the taxable value gives an approximate dollar amount for how much your tax bill for 2024 will go up.

How inflation mixes with property taxes in Michigan

Thirty years ago on March 15, 1994, Michigan voters approved a constitutional amendment that included authorizing a 6% sales taxes and limiting how high a taxable value on many homes can go up in a given year.

Under what's often referred to as Proposal A, the taxable value on a primary residence can go up based on the inflation rate in a year or 5%, whichever is less, for many homes. Again, that limit applies if there were no changes in homeownership or major renovations, such as adding a family room or bedroom to the property.

Make no mistake, some homeowners will see much bigger increases in their taxable value in 2024 under some circumstances. If you bought a home — or took on a big construction project, such as adding a bedroom — your taxable value could go up more than that 5% limit.

Many new home buyers regretfully don't realize that the limit on the taxable value does not apply to the home the year after it is sold. After a sale, the cap is uncapped the year following an ownership transfer of a property. Then, the taxable value will be the same as the state equalized value, which is half of the property's cash value. New homeowners often pay far more in property taxes than the person who sold them the home if the former owner lived there for 20 years or 25 years.

When inflation was low, it was pretty easy to ignore the notices that come out months before actual summer property tax bills hit in July. But I've been writing about the impact of inflation on property tax bills in Michigan since 2022, once inflation exploded after the COVID-19 pandemic.

Homeowners see sizable hikes three years in a row
