Estimated annual property taxes = projected post-transfer value used for taxation × applicable mills ÷ 1,000, plus applicable fees and separately billed charges. Confirm the projected value and applicable mills with the local assessor rather than assuming a statewide rate. Use the State of Michigan Property Tax Estimator from Michigan Treasury to cross-check your calculation.
The seller’s bill is not a reliable forecast. It reflects the seller’s assessment history and exemptions, which may differ from yours. Following a qualifying transfer, the value used to calculate taxes resets to State Equalized Value (SEV) in the next calendar year—not immediately at closing. Not every transfer triggers that reset; confirm how your transaction will be treated with the local assessor. Michigan Compiled Laws § 211.27a governs this reset.
Purchase price divided by two is only a rough planning assumption. SEV represents 50% of true cash value, not an automatic assessment of half your purchase price. Ask the assessor about projected SEV before relying on that shortcut. Michigan Treasury’s Property Tax Estimator provides an estimate, not a final tax bill.
For a realistic ownership budget, verify the school district, owner-occupancy exemption eligibility, special assessments, and applicable administration fees with local officials. Keep estimated annual taxes separate from your lender’s escrow requirement and any tax prorations calculated at closing.
Why the seller’s property tax bill may not predict yours
Value | Definition | Role in estimating taxes | Buyer caution |
|---|---|---|---|
Market value / true cash value | The usual selling price a property could obtain in a private sale. | Assessors estimate this value using local market trends and sales studies. | An individual purchase price does not automatically establish true cash value. |
Assessed value (AV) | 50% of the property's true cash value. | Provides the valuation that undergoes county and state equalization. | It is not ordinarily the figure used directly to calculate the annual tax bill; a sale does not automatically set it. |
State Equalized Value (SEV) | Assessed value after county and state equalization; represents 50% of true cash value. | Becomes the tax calculation base in the calendar year following a qualifying transfer of ownership. | SEV is not subject to the annual growth cap. Not every transfer triggers uncapping. |
TV | The tax calculation base: generally the lesser of SEV or capped value, with a reset to SEV after a qualifying transfer. | The figure multiplied by applicable local tax rates to calculate property taxes. | The seller's capped figure generally governs the purchase year, but may not predict the following calendar year's bill. |
Purchase price | The price paid in an individual property sale. | Individual sales contribute to the market data assessors analyze, but properties are evaluated independently. | Do not assume the sale price automatically sets assessed value or true cash value. |
Property taxes:
the post-purchase timeline
A seller’s tax bill reflects their capped base—not necessarily your future housing budget.

Seller’s capped base generally continues
The seller’s existing capped tax calculation base generally remains in place for the rest of the calendar year.
Reset after a qualifying transfer
The tax calculation base uncaps to that year’s State Equalized Value (SEV)—not automatically to the purchase price. A gap between the seller’s capped base and SEV can mean a higher tax bill.
Annual cap applies again
The reset base becomes subject to the statutory cap. Capped growth is limited to inflation or 5%, whichever is lower, with additions and losses accounted for separately.
Not every transfer triggers uncapping
Certain transfers involving spouses, family members, trusts or estates may qualify for an exemption when statutory conditions are met. Confirm the applicable requirements with the local assessor and Michigan Treasury guidance.
Other changes can affect your bill
Improvements, additions and exemption changes can affect values or taxes independently of a sale. The annual cap is not a guarantee that the total tax bill cannot increase further.
Estimate Your Annual Property Taxes After Buying

Michigan Property Tax Estimator
Use an assessor-confirmed projected SEV and your applicable annual millage to plan for post-purchase taxes.
Before relying on this estimate
A seller’s bill reflects their taxable value and exemptions, not necessarily yours. SEV, taxable value and purchase price are distinct; do not substitute the purchase price for projected SEV. For a transfer subject to uncapping, taxable value resets to that year’s SEV in the next calendar year. Not every transfer uncaps—confirm with your local assessor.
Verify the school district, annual millage, PRE eligibility and separately billed assessments with local officials. Confirm escrow with your lender and closing prorations with your closing professional. The monthly figure is a budgeting equivalent, not lender escrow or a closing proration.
This planning tool has no legal standing and does not determine PRE eligibility or automatically supply a PRE reduction. Compare with the official Michigan Treasury Property Tax Estimator and confirm the assessment and final taxes with local officials.

Verify your estimate inputs with the local assessor
Use the parcel identification number and legal description to confirm the assessing jurisdiction and school district with the local assessor. A mailing address or postal city may not match either boundary.
Match those confirmed details to the inputs you use for your estimate rather than selecting a jurisdiction based only on the address.
Request the projected State Equalized Value (SEV) and ask whether your transaction constitutes a transfer of ownership that triggers uncapping. Under MCL 211.27a, a qualifying transfer triggers uncapping in the calendar year following the transfer; not every transfer has that result.
The seller’s bill may reflect years of capped assessment growth, so it is not a reliable forecast of your post-purchase taxes. Ask the assessor which projected figure to use rather than treating the purchase price as SEV. Michigan’s Transfer of Ownership Guidelines explain the transfer framework.
Do not assume the seller’s principal residence exemption transfers to you. You must independently qualify by owning and occupying the property as your primary residence and filing your own documentation.
Confirm eligibility and filing timing with the assessor. Under MCL 211.7cc, the Principal Residence Exemption Affidavit, Form 2368, must be filed on or before June 1 for the summer levy or November 1 for the winter levy.
Ask for the applicable PRE or non-PRE millage for the confirmed parcel and school district. Use the treatment that matches your eligibility and filing status, not the seller’s status or an assumed statewide total.
The principal residence exemption removes qualifying local school operating taxes of up to 18 mills. It does not eliminate other levies, including school debt service, building funds and the 6-mill State Education Tax. Michigan Department of Treasury guidance distinguishes these charges.
Ask the assessor or local treasurer to identify special assessments and separately charged items affecting the parcel, including charges for drains, sewers, roads, sidewalks, streetlights or rubbish service. Confirm whether they appear on the tax bill or are billed separately.
Itemize these charges outside the baseline property-tax calculation rather than assuming the millage calculation includes them. Also ask whether property improvements affect the projected assessment used in your estimate.
Michigan’s Property Transfer Affidavit, Form 2766, must be filed with the local city or township assessor within 45 days of the transfer under MCL 211.27a. Confirm the filing obligation for your transaction and retain proof of submission.
Ask the assessor whether a statutory exception to uncapping applies and what supporting documentation is required. Do not assume that an exception to uncapping also removes the affidavit filing obligation.
Build Your Tax Budget Before Making an Offer
Get the current tax bills. Treat the seller’s bills as historical background, not your forecast. They reflect the seller’s ownership history and may not represent your post-purchase costs.
Verify the inputs. Ask the local assessor to confirm projected SEV, applicable tax rates, school district and exemption status. Confirm whether your transfer would trigger uncapping in the following calendar year; not every transfer does.
Budget for the following year. Estimate annual taxes using the verified inputs, then compare scenarios if values or rates change. A monthly equivalent is a budgeting aid—not a lender escrow quote. Summer and winter bills are installments of the annual levy, not separate annual tax liabilities; confirm local payment deadlines.
Review escrow with your lender. Ask which annual tax estimate supports the lender’s payment estimate, whether it accounts for post-transfer changes, and how potential escrow shortages would be handled. Keep estimated taxes distinct from the lender’s required escrow payment.
Clarify closing prorations. Ask your closing professional how the purchase agreement allocates taxes between buyer and seller and how those amounts appear on the settlement statement. Prorations are contract-specific closing allocations—not a forecast of your future annual tax bill.
