Property tax in Allegan County, Michigan

Who sends the property tax bill in Allegan County, and how do you pay it?

The bill comes from your city, township or village treasurer (the Allegan County Treasurer collects only delinquent taxes). The value it is based on is set by a separate office, your city or township assessor, which is who to ask if the value looks wrong.

In Michigan the county does not send the regular property tax bill. Your city, township or village treasurer bills summer and winter taxes and takes payment for both; due dates, payment options and late charges differ from one community to the next, so use the dates printed on your bill. Only taxes left unpaid into March go to the Allegan County Treasurer, at 3283 122nd Avenue in Allegan, which takes delinquent payments online and by phone through Official Payments for a fee. The county's own FAQ still gives June 30 as the Tax Tribunal deadline; state law now sets July 31 for homes. Parts of the cities of Holland and South Haven lie in Allegan County. The county Equalization Department sets countywide equalization factors, while each city and township assessor sets individual values.

When are property taxes due in Allegan County?

For the 2026 bill, Allegan County has one due date: March 1, 2027. This is not the due date on your bill. Your city, township or village treasurer bills summer taxes on July 1 and winter taxes on December 1, and each bill prints its own due date. The county says summer taxes are usually due by September 14, with 1% interest added from September 15 (cities and charter townships set their own dates and can differ), and winter taxes are due by February 14. Taxes paid after February 14 can carry a 3% late penalty if your city or township has authorized it. State law turns taxes still unpaid at the end of February over to the county treasurer. February 28, 2027 is a Sunday, and state law then moves the last day to the next business day, Monday, March 1, 2027. Taxes still unpaid are turned over to the Allegan County Treasurer, and a 4% administration fee and interest of 1% a month are added. A $15 fee is added on October 1. If the taxes are still unpaid a year later, on March 1 the property is forfeited to the county treasurer: a $175 fee and recording fees are added, and interest rises to 1.5% a month back to March 1 of the year before. A property still unpaid by March 31 of the following year is foreclosed, all rights to it are lost, and it is sold at auction. The county does not accept postmarks on that final deadline, and neither the local nor the county treasurer can waive interest or penalties because a bill was not received.
