Michigan property tax appeals start with the assessment notice

Every year, Michigan property owners receive an assessment notice showing important values used to calculate property taxes. This notice may include assessed value, taxable value, state equalized value, classification, exemption information, and appeal instructions.

Do not assume the notice is correct just because it came from the assessor. Michigan assessments are often created through mass appraisal methods, neighborhood data, prior sales, property records, land tables, and local valuation rules. Those systems can miss property-specific facts.

If your value increased, your property record is wrong, your home needs repairs, or similar homes sold for less than your assessment, it may be worth reviewing your appeal options.

Step 1: Review your Michigan assessment notice

Your assessment notice is the starting point. Before filing anything, review the notice carefully and write down the following:

• Parcel number
• Property address
• Owner name
• Property classification
• Assessed value
• Taxable value
• State equalized value
• Principal Residence Exemption status
• Appeal instructions
• March Board of Review dates

Michigan deadlines can move quickly. Many residential valuation appeals must begin at the local March Board of Review. If you miss the local review window, you may lose the ability to challenge that year valuation.

Step 2: Check your property record for mistakes

Property record errors are one of the easiest places to start. If the assessor has incorrect information about your home, the valuation may be too high.

Look for mistakes such as:

• Incorrect square footage
• Wrong number of bedrooms or bathrooms
• Finished basement listed incorrectly
• Garage, porch, deck, or addition errors
• Wrong lot size
• Incorrect year built
• Incorrect condition rating
• Property classified incorrectly
• Features listed that the home does not have

Small errors can create large tax consequences, especially in Michigan communities with higher millage rates. If the record says your home is bigger, newer, more improved, or in better condition than it really is, that can support an appeal.

For county-level help, review pages such as Oakland County property taxes, Wayne County property taxes, Macomb County property taxes, and Washtenaw County property taxes.

Step 3: Compare your assessment to recent sales

Comparable sales are one of the strongest tools in a Michigan property tax appeal. Comparable sales are recently sold homes that are similar to your home in location, size, age, style, lot size, and condition.

Good comparable sales can show whether your assessment is higher than the market supports. If homes similar to yours sold for less than your assessed value, that may support a lower valuation.

Strong comparable sales usually have:

• A recent sale date
• A nearby location
• Similar square footage
• Similar lot size
• Similar age and style
• Similar number of bedrooms and bathrooms
• Similar condition
• A normal open-market sale

A few strong comparable sales are usually more useful than a long list of weak comparisons. Avoid relying on homes that are much larger, newly renovated, waterfront, in a different school district, or otherwise clearly superior to your property.

Step 4: Review the Principal Residence Exemption

Michigan homeowners should confirm whether the Principal Residence Exemption is correctly applied. The Principal Residence Exemption, often called PRE, may reduce the tax burden on an owner-occupied primary residence by exempting the property from local school operating millage up to 18 mills.

If your PRE is missing, denied, incorrectly removed, or not properly updated after a purchase, your tax bill may be higher than it should be.

Check your notice and tax bill for the PRE percentage. If something looks wrong, review the local assessor instructions and Michigan Treasury forms before the applicable deadline.

Step 5: Prepare your evidence before the March Board of Review

For many Michigan residential property owners, the March Board of Review is the first formal step in the appeal process. Local rules vary, so check your city or township instructions for dates, formats, forms, and whether written appeals are accepted.

Your appeal packet should be clear, organized, and focused. The goal is to show why the assessment should be reduced based on evidence, not emotion.

Useful evidence may include:

• Assessment notice
• Property record card
• Recent comparable sales
• Photos showing condition issues
• Repair estimates
• Appraisal or market value evidence
• Evidence of incorrect square footage or property details
• Comparable assessments of similar homes
• Exemption documents if applicable

If your home has outdated interiors, water problems, foundation issues, needed repairs, traffic noise, drainage problems, or other negative value factors, include photos and supporting documents where possible.

Step 6: Attend or submit to the local Board of Review

The Board of Review gives property owners a chance to explain why the assessment should be changed. Some local boards allow in-person appearances, written protests, phone hearings, video hearings, or a combination of methods.

Before the meeting or submission deadline, confirm:

• Where the appeal must be filed
• Whether an appointment is required
• Whether written appeals are accepted
• How many copies are needed
• What forms are required
• The exact deadline and time
• Whether email, online, mail, or in-person filing is allowed

At the review, keep your explanation simple. Focus on the assessed value, comparable sales, property record errors, and evidence that supports a lower value.

Step 7: Review the Board of Review decision

After the Board of Review, you should receive a decision or notice showing whether the assessment was changed. Keep a copy of that decision with your tax records.

If your value is reduced, your tax bill may be reduced as well. If the bill has already been issued or paid, the result may involve a corrected bill, credit, escrow adjustment, or refund depending on local rules and timing.

If the Board of Review does not reduce the assessment, you may still have a next step through the Michigan Tax Tribunal if you meet the filing requirements and deadline.

Step 8: Consider the Michigan Tax Tribunal

The Michigan Tax Tribunal hears Michigan state and local tax appeals, including property tax disputes. For many residential valuation appeals, a local Board of Review protest is required before a further appeal can be filed with the Tribunal.

Residential property appeals to the Michigan Tax Tribunal are commonly associated with a July 31 filing deadline for the tax year involved. Commercial and industrial property appeals often have a different deadline. Always verify the current filing deadline for your property classification and tax year.

The Tribunal process may involve a petition, filing fee, answer from the local unit, evidence exchange, informal hearing, decision, and possible further appeal rights. Homeowners should read the Tribunal instructions carefully and keep every notice received.

Common Michigan property tax appeal mistakes

Michigan homeowners often lose appeal opportunities because of simple mistakes. Avoid these common problems:

• Missing the March Board of Review window
• Waiting until the tax bill arrives to review the assessment notice
• Using asking prices instead of closed comparable sales
• Using homes that are not truly comparable
• Failing to document property condition issues
• Not checking the property record card
• Ignoring the Principal Residence Exemption
• Submitting emotional arguments without evidence
• Not keeping copies of everything filed
• Missing a Michigan Tax Tribunal deadline after the Board of Review

The best appeal is organized, factual, and filed on time.

What if your Michigan property taxes are high but your value is correct?

A high tax bill does not automatically mean the assessment is wrong. Michigan property taxes can be affected by millage rates, school taxes, local debt, special assessments, taxable value rules, and exemptions.

If the value is accurate, you may still want to check whether exemptions or reductions are missing. If the value is not accurate, an appeal may be appropriate.

To appeal property taxes in Michigan, start by reviewing your assessment notice, checking your property record, gathering comparable sales, confirming your exemptions, and filing with the local March Board of Review before the deadline.

If the local result is not favorable, a further appeal may be available through the Michigan Tax Tribunal, depending on your property type, filing history, and deadline.

The goal is simple: make sure you are not paying property taxes based on a value that is too high or a record that is wrong.
