Property taxes in Eaton County are billed twice a year by your local township or city treasurer, calculated by multiplying your parcel’s Taxable Value by the combined millage rate of every jurisdiction that covers it. Summer bills are due September 14 and winter bills are due February 14. Several exemptions can cut what you owe, and missing payments triggers a three-year clock that ends in foreclosure.
How Your Bill Is Calculated
Three numbers drive every property tax statement. The local assessor sets your property’s True Cash Value, then records the Assessed Value at 50% of that figure.1Michigan Legislature. Michigan Compiled Laws 211.27a – Adjusted Assessed Value and Taxable Value of Property After county equalization, that becomes your State Equalized Value (SEV). The number that actually produces your bill, though, is the Taxable Value. State law caps its annual increase at 5% or the rate of inflation, whichever is less, so it usually sits below SEV. The cap resets only when the property changes hands, at which point Taxable Value jumps up to the current SEV.
Your bill equals Taxable Value times the total millage rate. A mill is $1 of tax per $1,000 of Taxable Value. A home with a Taxable Value of $100,000 in a jurisdiction levying 30 mills owes $3,000. Millage rates combine allocated mills authorized by law with voter-approved levies for libraries, fire protection, community colleges, and similar services.
What Rates Look Like Across the County
Total millage rates vary widely depending on which township or city you’re in and which school district serves the parcel. For 2025, rates for homestead properties claiming the Principal Residence Exemption ran from roughly 16 mills in Mulliken Village to over 50 mills in parts of Lansing City within the Lansing School District.2Eaton County. Certified Tax Rates 2025 Non-homestead properties, including rentals, second homes, and commercial parcels, pay more because they’re charged the full school operating millage.
For scale: a homeowner in Charlotte City with the Principal Residence Exemption paid about 32 mills, while a homeowner in Delta Township within the Grand Ledge School District paid about 20.5 mills. On a $150,000 Taxable Value, the difference between 20 and 32 mills is roughly $1,800 a year. The Eaton County certified rate sheet, updated annually, lists the exact rate for every taxing unit.2Eaton County. Certified Tax Rates 2025
Payment Deadlines and Penalties
Taxes are collected in two installments:
- Summer taxes are billed July 1 and due by September 14. If the 14th falls on a weekend or holiday, the deadline extends to the next business day. Payments made after the deadline accrue interest at the rate applied to that year’s delinquent levies.3Michigan Legislature. Michigan Compiled Laws 211.44a – Summer Property Tax Levy
- Winter taxes are billed December 1 and due by February 14 of the following year. A property tax administration fee of up to 1% applies to payments made before that date, and payments made after February 14 trigger a 3% late penalty on top of the administration fee.4Michigan Legislature. Michigan Compiled Laws 211.44 – Collection of Taxes
Senior citizens, people with disabilities, veterans, and farmers who meet income thresholds can defer the summer bill until the winter bill is due by filing with their local treasurer before September 15. The deferment doesn’t reduce the amount owed, but it avoids the late penalties that would otherwise start on September 15.
How to Pay
Current-year taxes go to your local township or city treasurer, not to the county. Most jurisdictions offer the same channels:
- Online through a third-party processor. Credit and debit card payments usually carry a convenience fee around 3%; bank account payments cost less.5Eaton Township. Eaton Township Property Taxes
- By mail to the township or city treasurer. The USPS postmark counts as your payment date, so a check postmarked September 14 is on time even if it arrives later.
- In person at the municipal office during business hours, with an immediate receipt.
- In the after-hours drop box most municipal buildings maintain.
You’ll need the parcel number from your tax statement. If the statement is lost, look up your parcel and current balance on the Eaton County BS&A portal at bsaonline.com, which accepts searches by owner name, address, or parcel number.6Eaton County. Online Services
Exemptions That Lower What You Owe
Principal Residence Exemption
The Principal Residence Exemption (PRE) removes the 18-mill school operating tax from your bill, worth $1,800 for every $100,000 of Taxable Value. You must own and occupy the property as your primary home and file Form 2368 with your local assessor by June 1 for the summer bill or November 1 for the winter bill.7Michigan Legislature. House Bill 4861 – Principal Residence Exemption Analysis You can only claim PRE on one property. If you move, rescind the exemption on the old home and file a new affidavit for the new one.
Disabled Veteran Exemption
Veterans rated permanently and totally disabled by the U.S. Department of Veterans Affairs, or who receive specially adapted housing assistance, qualify for a complete property tax exemption on their homestead under MCL 211.7b.8Michigan Legislature. Michigan Compiled Laws 211.7b – Exemption of Real Property Used and Owned as Homestead by Disabled Veteran or Surviving Spouse An unremarried surviving spouse of a qualifying veteran can also claim it. The affidavit must be filed with your local assessor every year.
Poverty Exemption
Households with income below the federal poverty guidelines may qualify for a full or partial exemption on a principal residence under MCL 211.7u.9Michigan Legislature. Michigan Compiled Laws 211.7u – Principal Residence of Persons in Poverty Each township and city sets its own income and asset limits, which must be at least as restrictive as the federal guidelines. You apply by filing state Form 5737 with your local Board of Review, along with your federal and state tax returns.10Michigan Department of Treasury. Application and Affirmation for MCL 211.7u Poverty Exemption The Board meets in March, July, and December, and the application must be filed every year.
Qualified Agricultural Property Exemption
Farmland can receive the same 18-mill school operating exemption as a homestead. If the parcel is already classified as agricultural on the assessment roll, the exemption applies automatically. If it isn’t but more than 50% of the acreage is devoted to farming, file Form 2599 with the assessor by May 1 each year. Qualifying uses include crops, livestock, dairy, nursery stock, and Christmas tree production, but not managing a woodlot or running a garden center primarily for retail.
Homestead Property Tax Credit
Even if no exemption applies, you may recover part of what you paid through the Michigan Homestead Property Tax Credit, claimed on your state income tax return rather than through the assessor. Both homeowners and renters are eligible if their total household resources fall below the annually adjusted threshold; homeowners also face a Taxable Value cap.11State of Michigan. Homestead Property Tax Credit For renters, 20% of annual rent counts as property tax paid for the credit calculation.
Appealing an Assessment That Seems Too High
If your Assessed or Taxable Value looks too high, start with the March Board of Review in your township or city. Bring recent comparable sales, an independent appraisal, or documentation of condition issues that reduce value. Many municipalities also accept written protests by letter.
If the Board doesn’t resolve it, appeal to the Michigan Tax Tribunal. For residential and agricultural property, you must first have gone to the Board of Review, and the Tribunal filing deadline is July 31 of the same year. Commercial and industrial owners can skip the Board of Review and file directly with the Tribunal by May 31. The Tribunal’s Small Claims Division handles most residential disputes and is informal enough to navigate without an attorney.
After a Purchase: File the Transfer Affidavit
When you buy property in Eaton County, you must file a Property Transfer Affidavit (Michigan Treasury Form 2766) with the local assessor within 45 days of the transfer.12Michigan Department of Treasury. Property Transfer Affidavit The form triggers the uncapping of Taxable Value to the current SEV. Skipping it doesn’t save money. The assessor will catch the transfer later and adjust Taxable Value retroactively, with interest and penalties on the taxes that should have been billed.
For residential property, the penalty for missing the 45-day deadline is $5 per day, up to $200. It accrues automatically.
What Happens If You Fall Behind
On March 1 after the tax year, any unpaid taxes are returned as delinquent and transferred from your local treasurer to the Eaton County Treasurer. A 4% county administration fee is added, plus 1% per month in noncompounded interest from the original delinquency date. Your local treasurer can no longer accept payment once this transfer happens.13Eaton County. Treasurer
To pay delinquent taxes, work directly with the Eaton County Treasurer. Online payment is available through the county portal, but you’ll need the parcel number and the exact amount owed, which you can confirm first on BS&A.14Eaton County. Pay Delinquent Taxes Call the Treasurer for a current payoff figure, because interest accrues monthly and printed statements go stale.
The Forfeiture and Foreclosure Clock
If delinquent taxes stay unpaid into a second year, the consequences escalate quickly:
- March 1, Year 2: The property forfeits to the county treasurer. A $175 title search fee is added, and an additional 0.5% per month interest begins on top of existing charges.15State of Michigan. Foreclosure Process Timelines
- Show cause hearing: The foreclosing governmental unit sends notice by certified mail at least 30 days before a hearing where you must explain why the property should not be foreclosed.16Michigan Legislature. Michigan Compiled Laws 211.78i – Notice Requirements for Show Cause and Foreclosure Hearings
- Foreclosure judgment: If the court enters judgment, you have until March 31 of the following year to redeem the property by paying all delinquent taxes, interest, penalties, and fees in full. In a contested case, the redemption window is only 21 days after judgment.
- After redemption expires: Title vests absolutely in the foreclosing governmental unit. There is no further right to reclaim the property.
The full path from first missed payment to loss of title runs roughly three years, but fees and interest compound at every stage. A $2,000 bill can easily double by forfeiture. If you can’t catch up, contact the Eaton County Treasurer before the next stage lands.
