Property tax calculator
Enter a home's purchase price, choose the school district and homestead status, and see how the estimated yearly tax is figured.
Millage rates
| School district | Homestead | Non-homestead |
|---|---|---|
| Howell | 23.6309 | 41.6309 |
| Hartland | 27.9854 | 45.8990 |
Homestead means the home is your primary residence and you've filed a Principal Residence Exemption, which lowers your rate.
What's a mill?
One mill is $1 of tax for every $1,000 of taxable value. That's why the calculator divides by 1,000 before multiplying by the mills.
*This is an estimate. Half the purchase price approximates taxable value; your actual taxable value is set by the assessor and may differ. Contact the Treasurer's Office with questions about your bill.
Property taxes may change after a sale
In Michigan, a home’s taxable value is “capped” while the same person owns it. That means it can only go up by the rate of inflation or 5% each year, whichever is less. When a home is sold, the cap is lifted. This is called “uncapping.” The next year, the taxable value resets to the home’s State Equalized Value, which is about half of its market value. The cap then starts over from there.
Because of this, the taxes the previous owner paid may be much lower than what a new owner will pay. This calculator estimates the tax bill after uncapping.
