The Township is in excellent financial health and the Board will continue to monitor revenue and expenditures throughout the year.

Just a reminder, the last day to pay your summer property tax bill without interest is September 14. The
office will be open from 9am – 5pm. Payments must be received in the office or paid online by 5pm.
After 5pm, 1% interest will be added.

To defer your Summer taxes, you must either own eligible farmland or your gross income must be less
than $40,000 and meet one of the following criteria: 62 years of age; Paraplegic, hemiplegic or
quadriplegic; blind; permanently disabled; or eligible serviceperson. To avoid penalty, deferred taxes
must be paid by February 14 by 5 pm. Please click here for the application.
