Michigan Estate Tax and Inheritance Tax: What Families Actually Owe in 2026

When a family member dies in Michigan, the tax question surfaces fast — usually within the first few days, when someone realizes the estate needs to be settled and they don't know what the government is owed. The short answer is straightforward, but the full picture has important details that determine whether you owe anything at all.

Does Michigan Have an Estate Tax?

No. Michigan does not impose a state-level estate tax. It also imposes no inheritance tax. Both were eliminated, and the state has not reinstated either since.

This places Michigan in a majority of US states that have entirely stepped away from death taxes at the state level. Residents of states like Illinois, Massachusetts, and Maryland face state estate taxes that can start at estates above $4 million or even $2 million. Michigan families avoid that entirely.

This is a meaningful distinction if your loved one owned real estate, retirement accounts, or other substantial assets. None of those assets trigger a Michigan state death tax obligation — regardless of the estate's total value.

What About Federal Estate Tax?

Federal estate tax is a separate matter and applies uniformly across all 50 states. For deaths occurring in 2026, the federal estate tax exemption is $13.99 million per individual. That means a single person can pass up to $13.99 million to heirs before federal estate tax applies at all.

Married couples benefit from portability — a surviving spouse can elect to use the deceased spouse's unused exemption (DSUE), potentially shielding up to $27.98 million from federal estate tax.

For the vast majority of Michigan families, federal estate tax is simply not a factor. Estates with significant wealth — particularly those with large business interests, investment portfolios, or multiple real properties approaching or exceeding those thresholds — should consult a CPA or estate attorney before filing.

What Taxes Do Apply After a Michigan Death?

While neither estate tax nor inheritance tax applies in Michigan, families face other tax obligations that are commonly overlooked:

Final Income Tax Return (Form 1040) The deceased's final federal income tax return must be filed for the year they died, covering income earned from January 1 through the date of death. A surviving spouse can file jointly for that final year. The due date follows the standard April 15 deadline for the tax year of death.

Estate Income Tax (Form 1041) If the estate generates income after death — from rental properties, dividends on investment accounts, or interest on bank accounts before they are distributed — that income is taxable and must be reported on IRS Form 1041, the U.S. Income Tax Return for Estates and Trusts. An Employer Identification Number (EIN) must be obtained from the IRS before opening an estate bank account.

Michigan Individual Income Tax Michigan requires a final state income tax return (Form MI-1040) for income earned by the decedent in the year of death. If the estate itself earns income, it may also owe Michigan fiduciary income tax. Michigan's flat individual income tax rate is 4.25%.

Property Tax Reassessment — The Hidden Risk This is the tax surprise most families don't anticipate. Under Michigan's Proposal A, residential property taxes are capped annually based on inflation. When a property changes ownership, that cap is typically removed and the taxable value "uncaps" — resetting to the current state equalized value (approximately 50% of market value). This can cause property taxes to double or triple.

However, Michigan law under MCL 211.27a(7)(d) exempts qualifying family transfers from this uncapping. If the property transfers to a surviving spouse, child, sibling, grandparent, or grandchild, the property tax cap is preserved. To claim this exemption, the new owner must file the Property Transfer Affidavit (Form 2766) with the local assessor within 45 days of the transfer. Missing this deadline triggers daily penalties — $5 per day up to $200 for residential properties — and potentially loses the exemption.

No State Estate Tax Doesn't Mean No Complexity

The absence of a Michigan estate tax removes one administrative burden, but it doesn't simplify the overall estate settlement process. Families still face:

• Probate court fees and inventory fees calculated on a sliding scale based on gross estate value
• Strict SCAO form requirements under Michigan's Estates and Protected Individuals Code (EPIC)
• A 91-day deadline to file the estate inventory with the probate court
• A 4-month creditor claims window that must close before distributions can begin
• Vehicle title transfer deadlines (21 days from transfer, or a $50 late fee applies)
• Property transfer affidavit deadlines (45 days from date of death or transfer)

Michigan also runs a Medicaid Estate Recovery Program (MERP), which functions as a state claim against probate assets when the deceased received Medicaid long-term care services after age 55. This is not a tax, but it operates like one for affected families — and it can consume estate assets if the estate goes through full probate. Assets that bypass probate entirely (such as homes titled under an Enhanced Life Estate Deed) fall outside MERP's reach under current Michigan law.

UK, Canada, and Australia Context

Families settling Michigan estates from abroad should note that US federal tax treaties affect what is owed. UK residents who inherit from a US estate are not subject to US inheritance tax (there is none). Canadian and Australian heirs similarly face no Michigan state tax, though they may face domestic reporting obligations in their home countries on inherited foreign assets. A cross-border tax advisor is worth consulting if significant assets transfer internationally.

Settling the Full Estate

Understanding the tax picture is one piece of a much larger administrative process. The complete estate settlement — from ordering death certificates and notifying agencies, to navigating probate court and distributing assets — involves dozens of specific steps with hard statutory deadlines under Michigan EPIC.

The Michigan Estate Settlement Guide walks through each phase in sequence: what to do in the first 48 hours, how to determine which probate path applies to your estate, which SCAO forms are required and when, and how to close the estate and make final distributions without triggering personal liability.

Michigan's lack of a state estate tax is good news. But the paperwork, the deadlines, and the probate process still require careful navigation — especially in the first 90 days after a death.
