Michigan’s property tax system is famously shaped by “Proposal A,” a constitutional amendment that firmly caps how fast your taxable value can grow. With a statewide effective property tax rate of 1.19%, property in Michigan is assessed at 50% of its True Cash Value. Because of Proposal A’s “pop-up” tax mechanic, your actual tax bill will look drastically different if you just purchased your home compared to a neighbor who has owned their identical home for 20 years (est., Tax Foundation 2026 / U.S. Census ACS 2023).
Michigan’s property tax framework is one of the most unique in the nation. While the statewide effective property tax rate sits at a moderate 1.19%, this average masks a massive disparity between long-term homeowners and new buyers. Because of Proposal A, passed in 1994, property taxes for long-time residents are artificially suppressed, while new buyers face an immediate “uncapping” of their taxable value, leading to severe sticker shock at the closing table.
The 50% State Equalized Value (SEV)
In Michigan, property is assessed at 50% of its True Cash Value (market value). This 50% figure is known as the State Equalized Value (SEV).
For example, if the local assessor determines your home could sell on the open market for $300,000, your Assessed Value (SEV) is constitutionally capped at $150,000.
However, your SEV is usually not the number used to calculate your tax bill. Instead, tax rates (millages) are applied to a different number called your Taxable Value (TV). Your Taxable Value can never be higher than your SEV, but for most homeowners who have lived in their house for a few years, the Taxable Value is significantly lower than the SEV.
Michigan statewide effective rate. On a $220,000 home, expect approximately $2,618 per year at the statewide average. If you recently purchased your home, your rate will likely be higher than this average (est., Tax Foundation 2026 / Census ACS 2023).
| Home Value | Annual Tax (est.) | Monthly Payment | vs. U.S. Average |
|---|---|---|---|
| $150,000 | $1,785 | $148 | +$435 above avg. |
| $220,000 | $2,618 | $218 | +$638 above avg. |
| $350,000 | $4,165 | $347 | +$1,015 above avg. |
| $500,000 | $5,950 | $495 | +$1,450 above avg. |
| $750,000 | $8,925 | $743 | +$2,175 above avg. |

Proposal A, Taxable Value, and the “Pop-Up” Tax
Proposal A was designed to prevent people from being taxed out of their homes during a real estate boom. Under Proposal A, a property’s Taxable Value (TV) can only increase by the Inflation Rate Multiplier (IRM) or 5%, whichever is less.
For example, if housing prices in your neighborhood jump by 15%, your SEV will jump by 15%. However, your Taxable Value will only increase by the IRM (which was 5.0% in 2024 and 3.1% in 2025). This gap between SEV and TV creates immense tax savings for long-term homeowners.
The “Pop-Up” Tax: The catch to Proposal A occurs when a home is sold. In the year following a transfer of ownership, the property’s Taxable Value “uncaps” and resets to match the new State Equalized Value (SEV). If you buy a home from someone who lived there for 30 years, their artificially low Taxable Value disappears, and the home is taxed on its full 50% market value. This often results in the new buyer’s tax bill being drastically higher than the previous owner’s bill.
The Principal Residence Exemption (PRE)
The Principal Residence Exemption (PRE) is the most critical tax break for Michigan homeowners. If you own and occupy your home as your primary residence, the PRE exempts you from paying the local school district operating millage (up to 18 mills). For a home with a $150,000 Taxable Value, the PRE saves the homeowner $2,700 per year.
To claim the PRE, you must file a Principal Residence Exemption Affidavit (Form 2368) with your local city or township assessor. If you buy a new home, you must file this form to receive the lower tax rate.
Homestead Property Tax Credit: Michigan also offers an income tax credit to help pay property taxes. For the 2024-2025 tax years, the state expanded the program limits to help combat inflation. Homeowners with Total Household Resources up to $71,500 and a home with a Taxable Value of $165,400 or less can qualify for a maximum credit of $1,900.
Major County Tax Rates in Michigan
Tax rates in Michigan are expressed in “mills” ($1 for every $1,000 of Taxable Value). Ingham, Wayne, and Washtenaw counties feature the highest effective property tax rates among the state’s most populous jurisdictions, driven by high municipal service costs and local school bonds.
Conversely, Livingston and Kalamazoo counties boast remarkably low effective tax burdens. Because these effective rates are based on Census data tracking what existing homeowners actually pay, they skew lower than the true statutory rate a new buyer will face upon uncapping.
| County | Effective Rate | Annual Tax on $220,000 Home | Notes |
|---|---|---|---|
| Wayne County | 1.51% | $3,322 | Most populous county (Detroit); high millage rates. |
| Oakland County | 1.23% | $2,706 | Wealthy suburban county north of Detroit; tracks near state average. |
| Macomb County | 1.28% | $2,816 | Suburban Detroit; slightly higher rate than Oakland. |
| Kent County | 1.03% | $2,266 | Includes Grand Rapids. |
| Genesee County | 0.88% | $1,936 | Includes Flint; lower effective tax rate. |
| Washtenaw County | 1.45% | $3,190 | Includes Ann Arbor; high rates driven by school and city levies. |
| Ottawa County | 0.99% | $2,178 | Fast-growing suburban county west of Grand Rapids. |
| Ingham County | 1.81% | $3,982 | Includes Lansing (State Capital); highest effective rate in top 10. |
| Kalamazoo County | 0.71% | $1,562 | Very low effective property tax rate. |
| Livingston County | 0.50% | $1,100 | Suburban county between Detroit and Lansing; lowest in top 10. |
Disclaimer and Methodology
This calculator provides estimates for planning purposes only, based on historical effective property tax rates (actual median taxes paid divided by median home values). Under Michigan’s Proposal A, property is assessed at 50% of its market value, but annual increases to your Taxable Value are strictly capped at 5% or inflation. This calculator uses “effective rates” to bypass this complex fractional math, providing a realistic estimate of what a typical homeowner in a given county pays today.
CRITICAL WARNING FOR NEW BUYERS:
- Because of Proposal A’s “pop-up” tax, the effective rates shown above represent an average heavily skewed by long-term homeowners who benefit from artificially capped Taxable Values.
- If you just purchased a home, your Taxable Value will “uncap” next year and reset to 50% of your purchase price. Your tax bill will be significantly higher than the previous owner’s bill.
- Never assume your future tax bill will equal what the seller paid last year.
How to get an accurate estimate:
- Use the Michigan Department of Treasury Property Tax Estimator, inputting your exact purchase price and local school district.
- Ensure you file your Principal Residence Exemption (PRE) Affidavit immediately after closing to exempt yourself from the 18-mill local school operating tax.
