Fenton Property Taxes After You Buy: Uncapping, the Nov. 1 PRE Deadline & What to Expect

Every fall I hear from someone who bought a home earlier in the year and just looked up next year's taxes. There's usually a pause.

Michigan has one property tax quirk that catches buyers off guard, whether they bought on Lake Fenton or a ranch near downtown: uncapping. Mid-October is the right time to talk about it, because a November 1 deadline can save new homeowners real money.

How Michigan Property Taxes Work (the Short Version)

Under Proposal A (1994), your property tax is based on your home's taxable value, not its market value. Each year the assessor sets a State Equalized Value (SEV), which is roughly half of what the home would sell for. Your taxable value is the lower of two numbers: your SEV, or last year's taxable value multiplied by inflation, with a hard cap of 5%.

For 2026, the State Tax Commission set that inflation multiplier at 1.027. That means taxable value on a home that didn't change hands could only go up 2.7% this year (Michigan State Tax Commission, Bulletin 14 of 2025).

So a long-time owner's taxable value can sit well below their SEV.

The Surprise: Your Taxable Value "Uncaps" the Year After You Buy

When a home sells, that protection goes away. State law says that after a transfer of ownership, the taxable value for the following calendar year resets to that year's SEV (MCL 211.27a). From then on, the cap starts over from your new, higher number.

Here's what that means for you:

• Don't budget off the seller's tax bill. The tax amount on the listing reflects the seller's capped value. Your bill could be noticeably higher starting next year.
• Your sale price isn't your assessment. The City of Fenton's own property tax guide says it's illegal in Michigan for an assessor to just set your SEV at your purchase price (City of Fenton, 2026 Guide to Property Taxes). Values come from a sales study of the market.
• Some family transfers are exempt. Transfers of residential property to certain close relatives (parents, children, siblings, grandchildren) generally don't trigger uncapping as long as the home isn't used commercially (same City of Fenton guide). If you're inheriting or buying a family home, ask your attorney or title company how this applies to you.

When I work with buyers, we estimate the uncapped taxes before we write an offer. Treasury's Property Tax Estimator is a good starting point, so your payment and escrow reflect what you'll actually pay.

Why November 1 Matters: File Your Principal Residence Exemption

This is the most time-sensitive part of the post. If the home you bought is where you actually live, you can claim a Principal Residence Exemption (PRE), which exempts you from part of the local school operating tax, up to 18 mills. On most homes, that's one of the biggest savings available.

The rules, straight from the State of Michigan (Treasury PRE guidelines):

• You file Form 2368 with the assessor of the city or township where the home is located.
• If you file by June 1, the exemption applies starting with that year's summer tax bill.
• If you file from June 2 through November 1, it applies starting with the winter tax bill.
• If you miss a deadline, the assessor can grant it retroactively for the current year and up to three prior years, as long as you qualified at the time.

The form is usually in your closing packet, but it can slip through the cracks during a move. If you closed this year, call your assessor's office or check your tax records now to confirm your PRE is on file.

A local wrinkle: "Fenton" covers more than one local government. Depending on the address, you may be in the City of Fenton, Fenton Township, or a neighboring township in Livingston County. Your form goes to whichever one actually assesses your parcel, which is not always the one your mailing address suggests.

Also, a lake cottage or second home doesn't qualify. The state's form says vacation homes, seasonal homes, and income properties can't be claimed (Form 2368). If you bought a weekend place on one of our lakes, plan for the higher non-homestead rate.

Selling This Fall? Two Things to Check Off

Sellers have tax paperwork too:

1. Rescind your PRE when you move. Once a home stops being your principal residence, you have 90 days to file Form 2602 (or a Conditional Rescission, Form 4640, if the home is for sale and you've moved out). Skipping this can mean extra tax, penalties, and interest (Form 2368 instructions).
2. Help your buyer set expectations. Buyers who understand uncapping early are less likely to get cold feet late in the deal.

Buyers have one more form: a Property Transfer Affidavit (Form 2766) filed with the assessor within 45 days of the transfer. Filing late can bring a daily penalty (Form 2766). The title company usually handles it, but it's worth confirming.

Keep an Eye on Your Mailbox in Early 2027

If you bought in 2026, your first uncapped assessment arrives with your Notice of Assessment before the March Board of Review. If you think the assessed value is more than half of what your home is actually worth, that's your chance to appeal (City of Fenton guide). The dates are printed on the notice, so read it closely when it shows up.
