Property taxes are one of the largest ongoing costs of homeownership, yet many buyers in Genesee and Livingston counties do not fully understand how Michigan's unique tax system works. From the Principal Residence Exemption to Proposal A's taxable value caps, the rules that govern your annual tax bill are unlike those in most other states. Understanding them before you buy — or before you list — can save you thousands of dollars.
This guide breaks down the key concepts every buyer and homeowner in Grand Blanc, Fenton, Linden, Columbiaville, and Tyrone Township needs to know, including how millage rates differ across communities, what the PRE exemption actually saves you, and why two homes with the same market value can have very different tax bills.
How Michigan Property Taxes Work: The Basics
In Michigan, property taxes are calculated by multiplying a property's taxable value by the local millage rate. One mill equals $1 of tax per $1,000 of taxable value. For example, if your home has a taxable value of $200,000 and your total millage rate is 30 mills, your annual property tax bill would be $6,000.
The critical distinction in Michigan is between a property's assessed value (what the local assessor determines the property is worth) and its taxable value (the number actually used to calculate your tax bill). For a newly purchased home, these two numbers start at the same point, but they diverge over time due to Michigan's Proposal A rules.
Proposal A: The Cap That Protects Long-Term Homeowners
Passed by Michigan voters in 1994, Proposal A limits how quickly your taxable value can increase each year. Specifically, the taxable value of a property can only rise by the lesser of 5% or the Consumer Price Index (CPI) annually. This means that even if your home's market value jumps by 10% in a single year, your taxable value — and therefore your tax bill — can only increase by the capped amount.
This cap is enormously valuable for long-term homeowners. A family that bought a home in Grand Blanc fifteen years ago may have a taxable value that is significantly lower than what a new buyer would pay for the same house today. This is not a loophole — it is the intended effect of the law, designed to give homeowners predictable, manageable tax increases over time.
The Taxable Value Uncap: What Buyers Need to Know
When a property is sold in Michigan, the taxable value "uncaps" and resets to the property's current assessed value. This means that if you buy a home where the seller has benefited from years of Proposal A caps, your taxable value — and your tax bill — will jump on day one. A home with a market value of $350,000 might have a taxable value of $220,000 under the previous owner, but it will reset to $350,000 (or close to it) when you close. This is one of the most important and least understood costs of buying a home in Michigan. Always ask your agent to estimate the post-sale tax bill before making an offer.
The Principal Residence Exemption (PRE): Your Largest Single Tax Benefit
Michigan's Principal Residence Exemption is one of the most significant tax benefits available to homeowners. The PRE exempts your primary residence from 18 mills of local school operating taxes — a meaningful reduction that can save you thousands of dollars each year.
To qualify, you must own and occupy the property as your primary home. You can only claim one PRE at a time and cannot claim a similar homestead exemption in another state. Filing is straightforward: submit a Principal Residence Exemption Affidavit (Form 2368) with your local city or township assessor by June 1 for the summer tax levy or November 1 for the winter tax levy.
Once approved, the exemption continues automatically as long as the property remains your primary residence. If you sell or move, you must file a Rescission of Principal Residence Exemption (Form 4640) by the same deadlines.
What the PRE Actually Saves You
If your home has a taxable value of $250,000, the 18-mill PRE exemption saves you $4,500 per year in school operating taxes. Over a decade of homeownership, that adds up to $45,000 — a substantial reduction in your total cost of ownership. If you are buying an investment property or a second home, be aware that non-homestead properties do not qualify for the PRE, and your effective tax rate will be significantly higher.
Community-by-Community: How Millage Rates Compare
While the PRE and Proposal A apply statewide, your actual tax bill depends on the total millage rate in your specific tax jurisdiction — which includes levies from the county, township or city, school district, intermediate school district, and various special assessments. These rates vary significantly from one community to the next, even within the same county.
Grand Blanc
Grand Blanc City falls within the Grand Blanc Community Schools district, which has made significant investments through a $149 million bond. Total homestead millage rates for properties within the city generally fall in the range of 30 to 35 mills, depending on the specific tax jurisdiction and any special assessments. The city's effective tax rate is approximately 0.58%, consistent with Genesee County averages. For a home assessed at $310,000 — near the current median list price — homeowners can expect an annual tax bill in the range of $5,000 to $6,500 after the PRE is applied.
Fenton
Fenton's tax landscape varies depending on whether the property is in Fenton Township (Genesee County), the City of Fenton, or the portions that extend into Livingston County or even Oakland County. For 2025, Fenton Township's official homestead millage rates ranged from 29.17 to 32.08 mills, depending on the school district assignment (Lake Fenton or Fenton Area Public Schools). Non-homestead properties in the same township face rates of 45.78 to 50.08 mills — a dramatic difference that makes the PRE exemption particularly valuable here. With Fenton's median list price near $408,000, a homestead buyer can generally expect annual property taxes between $6,000 and $8,500, depending on the specific location and school district.
Linden
The City of Linden is served primarily by Linden Community Schools and sits entirely within Genesee County. Total homestead millage rates generally fall in the range of 30 to 34 mills. Linden's combination of moderate millage rates and relatively accessible home prices makes it an attractive option for buyers seeking a lower overall tax burden within the Southern Lakes corridor. A home near the current median list price of $350,000 would typically carry an annual tax bill of approximately $5,500 to $7,000 with the PRE applied.
Columbiaville
Columbiaville sits in Lapeer County and is served by the Lapeer Community Schools district. Total homestead millage rates for the village and surrounding area generally fall between 28 and 33 mills. With home prices lower than the Southern Lakes corridor — the current median list price is approximately $232,000 — Columbiaville offers some of the lowest absolute tax bills in the region, often in the range of $3,500 to $5,000 annually for a homestead property. For buyers and investors seeking affordability, this is a meaningful advantage.
Tyrone Township
Tyrone Township straddles the Genesee-Livingston county line, and the tax picture depends on which side of the line a property falls. The 2025 residential homestead millage rates for Tyrone Township in Livingston County were 22.14 to 25.14 mills — notably lower than most Genesee County communities. Non-homestead rates ranged from 40.14 to 43.05 mills. With Livingston County's overall effective tax rate of approximately 0.41%, Tyrone Township homeowners generally enjoy the lowest property tax burden among these five communities. For a home valued at $450,000 — a common price point for new construction in the area — annual taxes might fall between $4,500 and $6,000, a significant savings compared to similar homes in Genesee County.

Why Two Homes With the Same Price Can Have Different Tax Bills
One of the most confusing aspects of Michigan property taxes for new buyers is discovering that two homes with identical market values can carry very different tax bills. This happens for several reasons:
- Taxable value vs. assessed value: The seller's long-tenured home may have a much lower taxable value due to years of Proposal A caps. Your new purchase resets to the assessed value.
- School district boundaries: School operating millage rates vary by district. A home in the Lake Fenton school district may have a different total millage than one just across the boundary in Fenton Area Public Schools.
- County lines: Tyrone Township in Livingston County has significantly lower millage rates than Genesee County communities. Crossing a county line — even by a few blocks — can meaningfully change your annual tax bill.
- Special assessments: Some properties carry additional levies for things like road maintenance, fire protection, or library services. These vary by district and are not always visible in a basic property tax lookup.
Practical Steps for Buyers
If you are buying a home in any of these five communities, take these steps to understand your true tax burden before closing:
Ask for the Seller's Current Tax Bill
Request a copy of the most recent winter and summer tax statements. These show both the assessed value and the taxable value — the difference illustrates the Proposal A cap benefit the seller has accumulated.
Calculate Your Post-Sale Tax Estimate
Using the purchase price (which becomes the new assessed and taxable value), multiply by the total local millage rate. Your agent or lender can help you run this estimate, or you can use the Michigan Treasury's online tax estimator at michigan.gov/taxes.
File Your PRE Affidavit Promptly
As soon as you close, file Form 2368 with your local assessor to claim the Principal Residence Exemption. Missing the June 1 or November 1 deadline means you could lose the exemption for that tax cycle, potentially costing you thousands.
Compare Tax Bills Across Communities
If you are deciding between Grand Blanc and Tyrone Township, for example, the tax difference alone could be $2,000 or more per year on a similarly valued home. Factor this into your total cost-of-ownership calculation alongside insurance, HOA fees, and commute costs.
What Homeowners Should Know About Annual Changes
Michigan property tax bills arrive in two installments: the summer tax bill (typically due July 1, with a late penalty after February 14 of the following year) and the winter tax bill (typically due December 1). Each year, local taxing authorities set their millage rates during their annual budget process, and the county equalization department adjusts assessed values to reflect market conditions.
If you believe your property has been over-assessed relative to comparable sales in your neighborhood, you have the right to formally appeal through your local board of review. The March board of review is the primary window for principal residence appeals, though the December board can handle poverty exemptions and clerical errors. An experienced local agent can help you understand whether an appeal makes sense and guide you through the process.
The Bottom Line: Taxes Matter More Than You Think
For many buyers, property taxes are an afterthought — a small line item buried in the monthly payment estimate. But in Michigan, the difference between a high-millage and low-millage community can amount to thousands of dollars per year, compounding into tens of thousands over the life of a mortgage. Understanding how Proposal A, the PRE, and local millage rates work gives you a significant edge as a buyer and a homeowner.
