Michigan PRE: the primary-home tax break

The short version

Michigan property tax is based on Taxable Value and mills. A mill means $1 of tax for every $1,000 of Taxable Value. PRE can remove up to 18 local school operating mills .

Simple example: if your home's Taxable Value is $150,000, then 18 mills is about $2,700 per year: $150,000 divided by 1,000, times 18.

PRE does not stop Michigan's property tax pop-up after a normal sale. It lowers the rate used to calculate the bill. The taxable value can still reset after you buy.

Who usually qualifies?

You usually need to own the home and live there as your main home. Michigan describes this as the place where you have your true, fixed, and permanent home, and where you plan to return when you are away.

Rentals, vacation homes, and second homes usually do not qualify. If your situation is unusual, such as a trust, life estate, active-duty military move, or a home you moved out of while trying to sell, ask the local assessor before assuming the answer.

Easy mistakes to avoid

• Assuming the title company filed it. They might help, but the safe move is to confirm with the assessor yourself.
• Confusing PRE with the Michigan Homestead Property Tax Credit. PRE lowers the property tax bill itself; the Homestead Credit is a refund claimed on your state income tax return. Different forms, different process, different timing.
• Thinking PRE stops the property tax pop-up . It does not. PRE lowers the millage rate, but the Taxable Value can still reset after a sale.
• Keeping PRE after moving out. When the home is no longer your main home, you generally need to file Form 2602 to remove it.

If you were looking for the state income-tax credit instead, start with the Michigan Homestead Property Tax Credit guide. Same word, different program.

If you move out

Once the home is no longer your main residence, you generally have 90 days to file a Request to Rescind Principal Residence Exemption (Form 2602) with the local assessor. Skip it, and you may end up paying the higher non-homestead rate on a home you no longer own or live in.

A special case: if you've moved into a new Michigan home but haven't sold the old one yet, Michigan allows a conditional rescission that keeps the lower rate on the old home for up to three years — but only if the old home is vacant, listed for sale, and not rented. That uses Form 4640 and requires annual renewal. If you're in this situation, ask the assessor before assuming.
