File An Appeal

How To Appeal

If you feel your property is over-assessed, you have the right to file an appeal with the Board of Review. The Board of Review accepts appeals from property owners by townships which open for appeals for a limited period. To file an appeal with the Board of Review, simply fill out a complaint form and return it to the Board of Review before your township’s appeal period is closed. Commissioner Cabonargi’s staff will research the appeal and prepare evidence for the Board to review and make a decision. You can also file an appeal in person at the Board of Review or at a satellite office. Please refer to the website for addresses and operating hours.

Now property owners may file an appeal online through the Board of Review’s website ( A property owner may also preregister an appeal before their township opens.
