Property Tax Uncapping in Michigan After a Death: What Heirs Need to Know

Most heirs focus on the federal estate tax and miss the real financial threat in Michigan real estate inheritances: property tax uncapping. Michigan has no state estate tax and no inheritance tax — but when a home changes hands, the local assessor has the power to reset property taxes to current market value. For a family cottage that has been owned for 30 years, this can double or triple the annual tax bill overnight.

Understanding which transfers trigger uncapping, which family relationships are protected, and what paperwork must be filed is essential before you record anything at the Register of Deeds.

How Michigan's Property Tax Cap Works

Under Proposal A (Michigan General Property Tax Act, MCL 211.27a), every property has two assessed values:

• State Equalized Value (SEV): Roughly 50% of the property's current fair market value, reassessed annually.
• Taxable Value: The figure actually used to calculate your tax bill. It is capped — it can only increase by the lesser of 5% or the rate of inflation each year.

Over decades of ownership, the Taxable Value often falls far below the SEV. A home bought for $120,000 in 1995 and now worth $400,000 might still have a Taxable Value of $175,000. The annual tax is calculated on $175,000, not $400,000.

A "transfer of ownership" breaks that cap. In the calendar year following a qualifying transfer, the assessor resets the Taxable Value to match the current SEV. For the example above, the heir's annual property tax base jumps from $175,000 to $400,000 — a 128% increase in one year.

Death of the property owner is, by default, a transfer of ownership. So is gifting property, selling it, or placing it in a trust without the proper structure.

Which Family Transfers Are Exempt from Uncapping

Michigan law provides a critical set of exemptions under MCL 211.27a(7)(u). Transfers of residential real property between certain qualifying relatives are exempt from uncapping — the Taxable Value carries over to the new owner unchanged.

Qualifying relationships that protect against uncapping:

• Spouse
• Mother or father
• Brother or sister
• Son or daughter
• Adopted children
• Grandson or granddaughter

Transfers that do not qualify and will trigger uncapping:

• Nieces and nephews
• Cousins
• Unrelated parties (friends, non-family caregivers, charities)
• Trusts (unless the trust beneficiaries are qualifying relatives and the trust is structured correctly)

Two important limits on this exemption:

1. Residential property only. Commercial property inherited by a qualifying relative will still uncap. A rental property with mixed use may uncap on the non-residential portion.
2. The assessor can require documentation. Under MCL 211.27a(7), the assessor may require the transferee to provide vital records proving the qualifying relationship within 30 days of the transfer. Have birth certificates, marriage certificates, or adoption decrees ready.

The Property Transfer Affidavit: Your 45-Day Deadline

The mechanism for claiming the family exemption is the Property Transfer Affidavit (Form 2766), filed with the local township or city assessor — not the probate court, not the Register of Deeds.

Filing deadline: 45 days from the date of transfer. Missing this deadline does not permanently forfeit the exemption, but it can lead to a penalty and an assessor dispute that takes months to resolve. File it promptly.

The form asks for:

• The property's legal description and parcel ID
• The type of transfer (inheritance, gift, sale)
• The relationship between the transferee and the decedent
• Whether the transfer qualifies for an exemption from uncapping

Check the box for the family transfer exemption and describe the relationship clearly. Attach supporting documentation if you have it — the assessor may request it anyway.

The form is available from your local assessor's office or at michigan.gov/taxes.

The Principal Residence Exemption Problem

A separate but related issue: the Principal Residence Exemption (PRE). Michigan homeowners who use their property as their primary residence receive a PRE that shields them from local school operating millages — up to 18 mills in annual savings.

When a homeowner dies, the PRE is automatically lost. A deceased person cannot maintain a principal residence. Assessors routinely remove the PRE as soon as they learn of the owner's death, which means the estate immediately receives non-homestead tax bills while the home sits vacant.

The conditional rescission: If the estate is actively trying to sell the home, it can preserve the PRE for up to three years under MCL 211.7cc(5). File Form 4640 (Conditional Rescission of Principal Residence Exemption) with the local assessor.

Requirements to maintain the conditional rescission:

• The property must be actively listed for sale
• It must be completely unoccupied
• It must not be leased to anyone
• It must not be used for any business purpose

Filing deadlines for Form 4640:

• On or before May 1 or June 1 to affect the summer tax levy
• On or before November 1 to affect the winter tax levy
• Must be refiled annually by December 31 to confirm continued compliance

Critical warning: if you rent the property while waiting for the market to improve, the conditional rescission is retroactively denied back to December 31 of the prior year, and you owe the back taxes plus penalties. This is not a gray area — the statute is explicit.

Lady Bird Deeds Prevent Uncapping at the Planning Stage

If the decedent used an Enhanced Life Estate Deed (Lady Bird Deed) to transfer the property, the uncapping risk is mitigated at the point of transfer. Michigan is one of only five states that recognize Lady Bird Deeds. When properly executed, the transfer to the remainder beneficiaries:

• Bypasses probate entirely
• Does not constitute a divestment for Medicaid purposes
• Preserves the step-up in tax basis for federal capital gains purposes
• Qualifies for the MCL 211.27a(7) family exemption from uncapping, provided the remainder beneficiaries are qualifying relatives

If the estate already transferred through probate or is actively being settled, a Lady Bird Deed is no longer an option — but it is a powerful planning tool for aging parents who want to protect their home from both property tax uncapping and Medicaid estate recovery.

Disabled Veteran Property Tax Exemption Carries Over

One specific exemption worth knowing: under Michigan law, a total property tax exemption applies to qualifying disabled veterans who use the property as their homestead. When a qualifying veteran dies, the unremarried surviving spouse can continue claiming this exemption indefinitely — it does not uncap, and it can apply to a new home the surviving spouse purchases after the veteran's death. File Form 5107 with the local assessor.

Practical Steps for Heirs Inheriting Michigan Real Estate

1. Identify your relationship to the decedent. If you are a spouse, parent, sibling, child, or grandchild, you likely qualify for the uncapping exemption. If you are a niece, nephew, or cousin, you do not.

2. Gather documentation. Birth certificates, marriage certificates, or adoption records establish the qualifying relationship. The assessor can and will ask.

3. File Form 2766 within 45 days of the transfer being recorded or completed. Do not wait.

4. Check the current Taxable Value and SEV at your local assessor's office or the municipality's online property lookup. The gap between the two tells you exactly how much is at stake.

5. If the property will sit vacant while you settle the estate, file Form 4640 immediately to preserve the PRE and avoid the jump to non-homestead tax rates.

6. Do not lease the property unless you have consulted with a tax professional about the PRE conditional rescission consequences.

Michigan's property tax rules after death interact directly with the estate's probate inventory, the timing of asset distributions, and the federal step-up in basis calculation.
