Taxation, Valuation & Appeals

Capped Value

Property’s Capped Value puts a limit on the amount that a home’s Taxable Value can increase. The Capped Value takes into consideration the prior year’s Taxable Value, the rate of inflation, as well as any property additions or losses. 

The formula for calculating the Capped Value is as follows: 

 (Prior year Taxable Value - Losses) * (Inflation Rate or 5% whichever is lower) + Additions = Current Year Capped Value 

Taxable Value

Your current year Taxable Value is the lesser of the Assessed Value or Capped Value. Taxable Value multiplied by the tax rate (i.e., the millage rate divided by one thousand) equals the estimate taxes which will be paid, excluding special assessments and any service fees. 

This is the value your property taxes are based on. A Taxable Value “uncaps” and becomes equivalent to the Assessed Value in the year following most ownership transfers.

If there was a change in ownership for the property, State law dictates that the following calendar year Taxable Value equal your Assessed Value. 

Appeals Process 

You may appeal the change in Assessed Value only to the March Board of Review. The March Board of Review has two main tasks. These tasks are (1) to review the assessment roll and correct any errors that were discovered after the assessment roll was prepared and (2) to listen to owner-related appeals regarding their assessment. The Board of Review looks to property owners to provide relevant information to support their contention of True Cash Value. The information may include, but is not limited to, recent sales activity involving their property, an appraisal of the property, sales of similar or “comparable” properties, and any other information deemed relevant about its valuation. 

The Grand Blanc Township March Board of Review will be meeting on the following dates for appeals of the 2026 values:

• Monday, March 9, 2026 
• Tuesday, March 10, 2026 
• Wednesday, March 11, 2026 

To Appeal in person, scheduling an appointment is advised, with the deadline being no later than the conclusion of the meeting on Wednesday.

Staff in the Assessing Department will review your assessment, upon request, prior to the start of the Board of Review. This review can only be done after your Notice of Assessment has been received. The review will determine your next steps in the appeal process. Sales Studies that were used to determine Market Value Adjustments for your property are available on the Assessing Departments web page.
