What is Assessed Value?

Assessed Value is a property value estimated by the assessor as of Tax Day. For 2021, Tax Day is December 31, 2020. That property value is subject to appeal at the March Board of Review.

What is State Equalized Value?

After all appeals are heard, the March Board of Review confirms the assessment roll. That roll is then subject to review by the county and state. Following those reviews State Equalized Value (SEV) is set. SEV is then considered to be 50% of Market Value or True Cash Value as determined on Tax Day.

What is the formula for Capped Value?

The Capped Value calculation is used to determine Taxable Value. 2021 Capped Value (CV): The 2021 formula is: (2020 TV-2021 Losses x IRM + 2021 Additions = 2021 Capped Value. The 2021 Inflation Rate Multiplier (IRM) is 1.014. Losses are considered to be physical losses to the property. Additions are considered to be physical additions to the property.

What is Taxable Value?

Taxable Value (TV) is the lesser of Assessed Value and Capped Value. In the year following a transfer of ownership (sale, gift, inheritance, etc.) the Taxable Value will be equal to the Assessed Value. In Michigan, taxes are based on Taxable Value, not State Equalized Value. Taxable Value can never be higher than the Assessed Value.

Why aren’t my assessed and taxable values equal to each other?

For most Novi properties, market values are increasing. The state constitution requires that properties are assessed at 50% of market value. However taxable value increases are limited to the 2021 statewide IRM or commonly called inflation rate of 1.014. So even if your neighborhood increases 10% because of market activity, your taxable value will only increase 1.014. In this example, it’s a good news/good news story for the homeowner. While values aren’t back to pre-recession levels, property owners are less underwater and property tax increases are limited.

Why isn’t my new assessment 50% of my purchase price?

The simple answer is that it is against the law. MCL 211.27 states that the purchase price is no longer the presumptive True Cash Value of a property. Market sale transactions for real property are used by Michigan assessors to compare assessed (AV) with the actual sale prices (market value) for those properties. Market value can be defined as the most probable price, as of a specific date, where both buyer and seller are knowledgeable and neither is under duress.

What is the time period considered in the 2021 Novi sales study?

The State Tax Commission requires counties to perform preliminary equalization using a 12 month and a 24 month sales study for each community. The study will be used that favors the taxpayer. Oakland County Equalization has determined that for 2021, Novi will use a 24 month study. For Novi that period is from April 1, 2018 to March 31, 2020 and includes over 2,000 sales. The 24 month sales study helps the taxpayer because it considers older sales. The City of Novi used one year sales studies from 2008 through 2011 when residential activity showed overall declines.

Why can’t I protest my taxes when I get my tax bill in July?

How do I qualify for the homestead exemption?

The homestead exemption is more correctly known as the Principal Residence Exemption (PRE). The qualifications are simple; you must own and occupy the home as your principal residence on or before June 1. Recent legislation allows for a partial homestead for homes acquired after June 1 and before November 1. A person or a married couple is allowed only one PRE in the State. You may not claim an exemption in any other state. The exemption continues until the use of the home as your principal residence changes. When the change occurs, you must notify the assessor’s office in writing. Recent legislation has allowed the granting of a second homestead under certain conditions. The Conditional Rescission is available when the previous homestead is not occupied or rented, and is listed for sale. Please contact the Assessing Department if you think you qualify for the additional exemption. The forms are available on on-line at under the Assessing forms link.

Why is my neighbor paying lower taxes than me?

On March 15, 1994, Michigan voters approved the constitutional amendments known as Proposal “A”.
Prior to Proposal “A” property tax calculations were based on State Equalized Value (SEV). Proposal “A” established “Taxable Value” as the basis for the calculation of property taxes. Increases in Taxable Value (TV) are limited to the percent of change in the rate of inflation or 5%, whichever is less, as long as there were no losses or additions to the property. The limit on TV does not apply to a property in the year following a transfer of ownership (sale).

Suppose your neighbor purchased his home March 20, 2020 and his 2020 State Equalized Value (SEV) was $75,000 and his Taxable Value was $55,000. His July 2020 tax bill will be calculated based on the prior owner's taxable value of $55,000 for 2020 only. In the year following the transfer the property becomes uncapped. Based on sales of homes in your neighborhood, your neighbor's new SEV for 2021 is $80,000. Because of Proposal “A”, your neighbor’s home became uncapped for tax year 2021 and his TV will be the same as his SEV for 2021. His July 2021 tax bill will be calculated using $80,000 TV instead of the prior year’s $55,000.

In other words since Proposal “A” passed, you can no longer compare your property taxes with your neighbors'. You can compare SEV, but remember to compare apples to apples. Items to compare would be square footage of the home, how many baths, is their basement finished, fireplace, garage, decks etc.

How are property taxes calculated?

Property Taxes = Taxable Value/1,000 x your local school district millage rate.
