The Good News...and the Bad News

Let's start with the market.

In 2023, the median selling price for a Maui condo increased 7.4%.

In 2024, it increased another 8.3%.

The good news?

Your investment was appreciating nicely.

The bad news? 

Your property taxes were appreciating right along with it.

Especially for short-term rental owners, where the tax rate is already...let's say...enthusiastic. 

 

Then 2025 Happened

After those nice increases, 2025 gave a lot of it back.

In fact, it gave all of it back.

The median condo price dropped from about $900,000 in 2024 to roughly $693,000 at the end of 2025.

So the bad news is:

A lot of owners lost equity.

The good news?

Well…

There isn’t any.

Because that’s not how property tax assessments work.

 

How Maui County Property Taxes Actually Work

Here’s where things get a little confusing.

Maui County property taxes run on a fiscal year from July 1 to June 30.

So the taxes you just paid last month apply to:

July 1, 2025 → June 30, 2026

Tax Year

Period Covered

2025–2026

July 1, 2025 – June 30, 2026

So far so good?

Now comes the part that makes people’s heads hurt.

 

The Property Tax Timeline

Your assessed value isn’t based on what the market is doing today.

Instead, it’s based on sales from the prior year.

Here’s the simplified, yeah right, real simple, Lee, timeline Maui County follows.

What It Means

January 1

The Important Part Most Owners Miss

Your January 1, 2026 assessment is based primarily on sales that occurred between:

July 1, 2024 – June 30, 2025

Assessment Date

Sales Data Used

January 1, 2026

July 1, 2024 – June 30, 2025

That means the county is typically running 9–18 months behind the real market.

So what does that mean this year?

The county’s model captures:

• The big price increases in late 2024
• Only part of the price decline in 2025

Which means…

Your assessment most certainly reflects prices that no longer exist.

 

How Maui County Calculates Property Values

Another thing that surprises property owners is how the county actually calculates value.

They are not individually appraising every condo and house every year.

That would be impossible.

Instead, Maui County uses something called mass appraisal.

Think of it as a statistical model that estimates property values based on recent sales.

The model analyzes factors such as:

• Recent closed sales
• Square footage
• Location
• View quality
• Bedroom count
• Property type
• Building or complex

Once the model determines a value range, it applies that estimate to all similar properties.

Example:

If several condos in a complex sell around $700,000, the county may estimate similar units in the building at roughly the same value.

 

Condo Assessments Work a Little Differently

For single-family homes, Maui County separates the assessment into two components.

Component

Description

Land Value

Value of the underlying land

Improvement Value

Value of the building

But condominiums are typically valued as a single unit based on comparable sales.

Typical factors include:

Factor

Impact

Floor level

Higher floors may command higher values

Ocean vs garden view

View premiums often apply

Square footage

Larger units typically valued higher

Bedroom count

Major driver of price

 

Why Your Assessment May Look Wrong

Mass appraisal works reasonably well when estimating thousands of properties.

But it’s not perfect.

Here are the most common reasons assessments differ from real market value.

Market Timing

Because the county uses prior-year sales data, assessments often lag the market.

In falling markets, assessments may be too high.

 

Limited Sales Data

Some condo complexes have very few recent sales, forcing the county to rely on older transactions.

 

Interior Condition

The county does not inspect interiors every year.

So two units may receive identical assessments even if they look very different.

Unit A

Unit B

Fully renovated

Original 1970 interior

Same tax value

Same tax value

 

Key Takeaways for Maui Condo Owners (2026 Property Tax Edition)

If you own a condominium on Maui, here are the most important things to understand about your 2026 property tax assessment.

Key Point

What It Means

Assessments lag the market

Maui County values properties using sales data from roughly 9–18 months ago

2026 assessments include part of the 2024 price surge

Some of the 2025 decline may not be fully reflected yet

Condo values rely heavily on comparable sales

The county estimates values using sales in your complex or similar properties

Interior condition is rarely considered

Renovated and original units often receive similar assessments

Owners can appeal

Property owners may file an appeal after notices arrive in March

 

Common Questions Maui Condo Owners Ask About Property Taxes

Why is my Maui property tax assessment higher than current market value?

Maui County assessments are based on prior-year sales data. Because of this, assessments often reflect market activity from 9–18 months earlier, which can make them appear too high during a declining market.

 

What sales does Maui County use to calculate condo assessments?

The county typically analyzes recent comparable sales within the same complex or similar complexes using a mass appraisal model.

 

Are Maui property tax assessments based on interior condition?

Generally, no. Maui County does not inspect interiors annually, so renovated and original units often receive similar assessments.

 

When are Maui property tax assessments determined?

Assessed values are established each year as of January 1, and those values determine taxes for the next fiscal year beginning July 1.

 

Can I appeal my Maui property tax assessment?

Yes. Property owners may appeal after assessment notices are mailed in March, typically by early April.

Appeals are usually supported by recent comparable sales showing a lower market value.

 

Final Thought

When your assessment notice arrives this spring, remember:

The county is looking in the rear-view mirror.

Your tax value is based largely on what the market looked like a year ago, not necessarily what buyers are willing to pay today.

Before you panic—or celebrate—compare the assessment with recent sales in your complex.

You may discover the county’s estimate is surprisingly accurate.

Or you may discover it’s time to consider filing an appeal.

Either way, at least now you understand how the system actually works.
