Frequently Asked Questions
How does Michigan's Proposal A affect Oakland County property taxes?
Proposal A limits annual Taxable Value increases to the lesser of 5 percent or inflation — regardless of how much the market value rises. Long-term Oakland County homeowners in communities like Bloomfield Hills, Birmingham, and West Bloomfield may have Taxable Values far below their State Equalized Value (50% of market value), paying significantly lower taxes than recent buyers of comparable homes. When the property is sold or transferred, Taxable Value uncaps and resets to the new SEV in the following year — often triggering a sharp tax increase for new buyers.
How do I appeal my Oakland County property tax assessment?
Property assessment in Michigan is done at the municipal level — contact your local city, village, or township assessor. The March Board of Review meets each year and is your primary appeal opportunity. Schedule an appointment with your local assessor's office before the Board convenes. The Board can reduce or maintain your assessment — it cannot raise it. If unsatisfied, file a petition with the Michigan Tax Tribunal (typically by May 31 for residential properties). Ownwell can manage the process and only charges if you save.
What is the Principal Residence Exemption (PRE) and how do I get it?
The PRE removes 18 mills of school operating taxes from your property tax bill for your primary residence in Michigan. File a PRE affidavit with your local city, village, or township assessor after closing on your home. You must also file a Property Tax Transfer Affidavit within 45 days of the transfer date to ensure proper recording of the ownership change.
Where do I file for probate in Oakland County, and can I file in person?
The Oakland County Probate Court is at 1200 N Telegraph Road, Pontiac. As of June 12, 2025, all filings are mandatory electronic through MiFILE at mifile.courts.michigan.gov — the court no longer accepts in-person, fax, or mail filings for most matters. Exceptions include emergency mental health transport petitions, deposit of original wills, and a few other specific matters. Call 248-858-0260 with questions.
How does Proposal A affect inheriting an Oakland County property?
When a parent or other owner dies and the property transfers to an heir, the Taxable Value uncaps in the following year and resets to the State Equalized Value — 50% of the new assessed market value. For properties in high-appreciation communities with large gaps between Taxable Value and SEV, this can mean a dramatic property tax increase for inheriting children. Proactive planning — including trusts that may defer uncapping in some circumstances — is advisable for Oakland County families with significant real estate.
