Aloha Maui property owners.

 

Every spring, property owners across Maui open their Notice of Property Assessment and ask the same question: Is this value actually correct?

 

Sometimes the answer is yes. But sometimes the county’s estimate does not line up with the market, especially when values move quickly.

 

Fortunately, Maui County provides a formal process to challenge an assessment. It is called a Real Property Tax Appeal.

 

The good news is that the process is fairly straightforward. The bad news is that timing matters. Miss the deadline and you generally need to wait another year.

 

The Two Things That Matter Most

Key Rule

Why It Matters

Timing

Appeals for the 2026 tax year must be filed by April 9, 2026. If mailed, they must be postmarked by that date. If delivered in person, they must arrive by 4:00 p.m.

The 20% Rule

For a valuation appeal, the main issue is whether the county’s assessed value exceeds market value by more than 20%. In practical terms, the taxpayer generally needs to show the property value is less than 80% of the total assessment.

 

Maui Property Tax Appeal Timeline

The appeal window opens shortly after assessment notices are mailed each year, and the filing period is relatively short.

Who Can File an Appeal?

Eligible Appellant

Typical Example

Property owner

Most common situation

Authorized representative

Attorney, consultant, or other representative with written authorization

Person contractually obligated to pay the property tax

Some leasehold or other contractual arrangements

If someone files on your behalf, a letter of authorization should be included with the appeal package.

 

Understanding the 20% Rule

The most common basis for appealing a Maui property tax assessment is the 20% rule.

The county materials explain this as a situation where the assessment exceeds by more than 20% the market value used by the County as the tax base. The hearing overview also states that the taxpayer needs to show the property value is less than 80% of the total assessment.

Example Scenario

Amount

Takeaway

County assessed value

$1,000,000

 

Estimated market value

$800,000

 

Difference

25%

A difference greater than 20% may support a valuation appeal

That does not automatically mean every disagreement wins. It means the taxpayer should be prepared to support a lower market value with solid evidence.

 

Other Valid Grounds for Appeal

Ground for Appeal

Explanation

Assessment exceeds market value by more than 20%

The most common appeal ground

Lack of uniformity or inequality

The methods used were applied incorrectly or produced an unequal result

Denied exemption

For example, a homeowner or other exemption was denied

Incorrect classification

Illegality

How to File a Maui Property Tax Appeal

Step 1: Complete Form DFT-595

Property owners must complete the County’s appeal form, Taxpayer’s Notice and Receipt of Real Property Tax Appeal (Form DFT-595). The form asks for the TMK, classification, owner contact information, the county’s assessed value, your opinion of value if you are appealing valuation, and the legal ground or grounds for the appeal.

Step 2: Gather Supporting Evidence

Two complete sets of your appeal form and evidence should be provided. Common supporting materials include comparable sales, a professional appraisal, photographs or documentation of physical condition issues, repair estimates, or a comparative market analysis.

Step 3: Pay the Filing Fee

Each appeal requires a $75 filing fee. The County instructions state that if the filing fee is not included, the appeal will not be accepted.

Step 4: Submit the Appeal

The appeal may be submitted online through the Maui property tax website, by mail to the Board of Review in Kahului, or in person at the Real Property Assessment Division.

Evidence Type

Example

Comparable sales

Recent sales of similar properties

Professional appraisal

Independent opinion of value

Property condition documentation

Photos, repair estimates, or deferred maintenance

Comparative market analysis

Broker or Realtor market analysis

What Happens After You File

Once the appeal is accepted, the matter goes to the Maui County Board of Review. The Board is made up of five county residents who serve as impartial decision-makers between the taxpayer and the assessor.

The County states that a hearing notice will be mailed at least 15 days in advance.

 

What to Expect at the Hearing

Step

What Happens

Case introduction

The County summarizes the appeal

Taxpayer presentation

You present your evidence and explain your position

County response

The assessor or County representative presents their analysis

Board questions

Board members may ask questions of either side

Decision

The Board may announce it later in writing after deliberation

The hearing materials state that the taxpayer is typically given about five minutes to present the case, although additional time may be allowed when reasonably necessary.

 

Important Things to Expect

  • You still must pay property taxes by the normal due dates, even if an appeal is pending.
  • If you prevail, any overpayment will be refunded as the County processes refunds.
  • The Board decides the correct assessment based on the evidence presented. It cannot reduce taxes simply because the owner cannot afford them, and it does not set tax rates.
  • If you disagree with the Board’s written decision, an appeal to the Tax Appeal Court generally must be filed within 30 days.

 

Common Misunderstandings

Misunderstanding

Reality

“My assessment went up a lot, so I should automatically win.”

A large increase by itself is not the legal test. The question is whether the current assessment is too high under the allowed grounds for appeal.

“I filed an appeal, so I can wait to pay my taxes.”

No. Taxes must still be paid by the due dates to avoid penalties and interest.

“The Board will compare me to my neighbor’s tax bill.”

The materials say assessed values of other property, the amount of the tax bill, prior year assessments, and year-over-year increases are generally inadmissible as evidence of value.

Final Thought

The Maui property tax appeal process is not something most owners deal with every day, but the core ideas are simple: watch the timeline, understand the 20% rule, gather solid evidence, and file on time if an appeal appears warranted.

 

The most important date to remember is April 9. Miss that filing deadline and you will usually have to wait until the next cycle.
