SEV Uncapping in Michigan: What Buyers Pay Year Two

The phone call I get most often after a closing isn't about the inspection or the title commitment — it's the one in late January, the year after closing, when the new tax bill shows up and a buyer says, "Holden, this is way higher than what the seller was paying. What happened?" What happened is the SEV uncap, and it's the single most under-modeled cost on a Grand Rapids, Hudsonville, Holland, or Forest Hills purchase. I want to walk through exactly what the State Equalized Value uncap does to your property tax bill, when it hits, and how to write an offer with the real number in mind.

The 2026 West Michigan market frame

February 2026 closed at a $308,000 median sale price in Grand Rapids, up 8.07% year-over-year, with 1.18 months of supply and 51 average days on market. Prices are climbing faster than Michigan's annual inflation cap, which means the gap between a long-held home's Taxable Value and its current market-driven SEV is widening every month. That gap is what you inherit — and pay tax on — in the year following your closing.

SEV vs. Taxable Value, in plain English

Michigan property tax assessment runs on two parallel numbers. State Equalized Value (SEV) is roughly 50% of the property's true cash value — the assessor's market-based number, recalculated annually. Taxable Value (TV) is the number your tax bill is actually computed against, and TV is capped year-over-year by Proposal A (passed March 15, 1994) at the lesser of 5% or the inflation rate.

For 2026, Michigan's inflation multiplier is 1.027 — meaning Taxable Values can grow at most 2.7% year-over-year as long as the property hasn't transferred. SEV, meanwhile, can move with the market: 8% in a hot year, 1% in a flat year. The cap is what creates the long-term wedge between SEV and TV. A Cascade home bought in 2010 might sit today at a TV of $145,000 against an SEV of $260,000 — a $115,000 gap of "untaxed" value the long-time owner has been quietly enjoying.

The transfer of ownership trigger

When the home sells, Michigan calls it a "transfer of ownership." The cap resets. Per MCL 211.27a, the new owner's Taxable Value in the calendar year following the transfer becomes equal to that year's SEV. That's the "uncap." On the Cascade example above, the buyer's year-two TV jumps from $145,000 to roughly $260,000 — a 79% increase in the taxable base. At a typical Cascade Township total millage of around 35–37 mills (PRE-claimed), that's a year-two bill rising from about $5,200 to roughly $9,400. Same house, same millage rate, $4,200 more in tax — entirely from the uncap.

This is the part most online tax history widgets miss. Zillow shows the seller's prior year tax bill. That's not your bill. Your bill in year two equals SEV × your township's PRE-claimed millage, where SEV is approximately half of what you just paid. Always model on SEV, not the prior TV.

The year-of-purchase vs. year-after-purchase confusion

Here's the timing trap. The uncap doesn't hit the year you close — it hits the year after. If you close in March 2026, your summer 2026 and winter 2026 tax bills run off the prior owner's capped Taxable Value. Easy money. Then on December 31, 2026, the assessor finalizes the 2027 SEV and TV, and your January 2027 statement reflects the uncapped TV for the full 2027 tax year. That's why I tell every buyer: budget your monthly payment off the year-two number, not the year-one number. Year one is a courtesy.

Buyers also frequently miss that this stacks with PRE timing. If the seller was non-homestead and you don't file Form 2368 by June 1 of year one, you're paying both the higher non-homestead millage AND walking into the uncapped TV in year two. Read my PRE vs. non-homestead breakdown alongside this — the two mechanics interact directly.

Finding the prior owner's TV before you write an offer

This is one of the highest-leverage moves in a competitive Forest Hills, Hudsonville, or Holland search. Before you offer, pull the property's current TV and SEV from the public assessor record — Kent County uses BS&A or AccessKent, Ottawa County uses miottawa.org, Allegan County publishes through accessallegan.com. Compare TV to SEV. If they're nearly equal, the prior owner likely bought recently and there's not much uncap to absorb. If the TV is half the SEV, you're stepping into a meaningful uncap.

Kent County: AccessKent property search — pulls the TV, SEV, and millage by parcel ID.
Ottawa County (Holland, Zeeland, Hudsonville, Allendale): miottawa.org/Equalization for SEV/TV history.
Township-level millage: each township publishes the current PRE and non-PRE rates on its website. Cascade, Ada, Caledonia, Byron, Forest Hills boundary townships all post these.

I run this check on every offer I write. It takes five minutes and routinely changes the buyer's understanding of monthly carrying cost by $200–$400 a month.

Sales that DON'T uncap the Taxable Value

Michigan law lists specific transfers that aren't treated as a "transfer of ownership" for uncapping purposes. The big ones — codified in MCL 211.27a(7):

Transfers between spouses — including divorce decree transfers
Transfers to a qualified relative (parents, children, grandchildren, siblings) where the recipient continues using the home as a principal residence — the "qualified family transfer" exemption added in 2014
Transfers via inheritance (probate or trust distribution) where the recipient meets occupancy and relationship rules
Transfers to or from a revocable living trust where the settlor remains the same
Land contract transfers — the uncap occurs when the equitable interest transfers, not at deed delivery
Transfers to correct a deed error

The qualified-relative exemption is huge for downsizers in Caledonia, Cascade, or Forest Hills who want to pass a long-held home to an adult child. Done right with Form 5107, the next generation inherits the capped TV, not the SEV. I've worked deals where this preserved $5,000–$8,000 a year in tax savings indefinitely.

What you can negotiate at closing to soften the uncap

You can't make the State of Michigan un-uncap the property. But you can offset the cost in the offer. Three moves I've used in 2026:

Seller credit toward year-two tax differential. On a $400K Hudsonville purchase where year two will run $3,500 higher than year one, ask the seller for a $3,500 closing credit framed as "tax adjustment." On homes that have been on market 51+ days, this lands. On homes selling at 98%+ of list in a multi-offer week, it doesn't.
Higher escrow cushion at the lender. Some lenders will analyze the post-uncap escrow up front so your year-two payment doesn't jolt — but they need you to flag the uncap math during application. Most automated underwriting systems use the prior TV.
PRE filing day-of-closing. Doesn't help with SEV uncap — it helps with the millage rate the uncapped TV gets multiplied by. 18 mills off the post-uncap bill is real money on top of the offset above.

FAQ

What's the difference between SEV and Taxable Value, in plain English?

SEV is the assessor's annual estimate of half your home's market value — it moves with the market every year. Taxable Value is the number your tax bill is computed against, and it's capped year-over-year at the lesser of 5% or inflation (2.7% for 2026). The cap means a long-held home's TV falls behind its SEV, sometimes dramatically. When the home sells, the next year's TV resets to the SEV — that reset is the uncap.

How can I find the previous owner's Taxable Value before I write an offer in Grand Rapids?

Kent County publishes parcel-level TV and SEV through AccessKent and BS&A — search by address, pull the most recent assessment, and compare TV to SEV. Ottawa County (covers Hudsonville, Holland, Zeeland, Allendale) does the same through miottawa.org. The gap between TV and SEV is the dollar amount your year-two tax base will rise. I run this on every offer I write.

Does the SEV uncap happen the year I buy or the year after?

The year after. Your closing-year tax bills run off the prior owner's capped Taxable Value. The uncap appears on the assessment notice in February of the year following your purchase, and your January and July tax statements that year reflect the full reset. That delay is why so many buyers think they got lucky on year one — and then panic in year two.

Are there sales in Michigan that DON'T uncap the Taxable Value?

Yes. MCL 211.27a(7) carves out transfers between spouses, qualified-relative transfers (parent to child, grandparent to grandchild, sibling to sibling) where the recipient occupies as principal residence, transfers via inheritance, transfers to or from a revocable living trust with the same settlor, and a few other narrow situations. Form 5107 is the affidavit for the qualified-relative exemption. These are real planning tools for downsizers passing a long-held Cascade, Forest Hills, or Holland home to the next generation.

What can I negotiate at closing to soften the SEV uncap surprise?

The cleanest move is asking the seller for a closing credit equivalent to the year-two tax differential — typical range is $2,500 to $5,000 on a $300K–$500K Grand Rapids home, depending on how long the seller held it. Whether you'll get it depends on the leverage in the deal. On a property that's been listed 51+ days, the answer is often yes. On a property going at 100%+ of list with multiple offers, the answer is almost never. Either way, file Form 2368 for PRE day-of-closing — that 18-mill reduction stacks against the uncapped base.
