Will the 2026 West Hartford Revaluation Make Your Property Taxes Go Up?

Something is about to arrive in the mail for every West Hartford property owner.

And if you are like most homeowners, you are probably going to open it and immediately ask two questions:

How much does the town say my house is worth now?

And:

What is this going to do to my property taxes?

West Hartford is completing its 2026 townwide revaluation, with properties being valued as of October 1, 2026. New valuation and assessment notices are expected later in the year.

After five years of significant changes in local real estate values, many homeowners should expect the numbers on those notices to look considerably higher than what they are used to seeing.

But before you take the assessed value from that letter, pull out a calculator and multiply it by West Hartford’s current mill rate, there is one thing I really want you to understand:

That is not how your new tax bill will be calculated.

The revaluation, the town budget and the mill rate are connected.

They are not the same thing.

What is the West Hartford 2026 revaluation?

Connecticut municipalities periodically reassess real estate so property values used for taxation more accurately reflect the current market.

West Hartford’s previous revaluation was based on October 1, 2021 values.

A lot has happened to the local housing market since then.

Homes in different neighborhoods and price ranges have not necessarily appreciated at exactly the same rate. Revaluation is partly about resetting those values so each property’s share of the overall tax burden reflects the current relationship among properties throughout town.

That is an important distinction.

The purpose is not simply to say, “West Hartford homes are worth more, therefore multiply the new value by the old tax rate.”

The entire grand list is changing.

How does the town determine what your house is worth?

West Hartford’s residential revaluation uses a mass-appraisal process.

That is different from the appraisal you might receive when purchasing or refinancing a home.

With an individual appraisal, someone can walk through your house.

They can see the renovated kitchen.

They can look at the condition of the bathrooms.

They can see the finished basement, yard, layout and overall level of maintenance.

A municipal revaluation has to value thousands of properties.

The process relies heavily on property records, neighborhood information, sales data and statistical models.

Recent arm’s-length home sales are particularly important because they show what actual buyers have recently been willing to pay.

Properties are also evaluated within neighborhoods because the market is not identical throughout West Hartford.

A house near Elizabeth Park and a house in Elmwood may have very different buyer pools and comparable sales.

The result is the town’s estimate of your property’s market value as of October 1, 2026.

Market value and assessed value are not the same number

This is another area where homeowners get understandably confused.

The town first establishes a market value.

Connecticut property assessments are then generally based on 70% of that value.

So if the town determines that a property has a market value of $700,000, the assessed value would be $490,000.

That assessed value is eventually used to calculate property taxes.

But there is still one missing number:

The new mill rate.

And that is why you cannot calculate your future tax bill from the revaluation notice alone.

Why you should not multiply the new assessment by today’s mill rate

West Hartford’s current mill rate was established using the existing grand list and current town budget.

The 2026 revaluation creates a new grand list.

If property values throughout town rise substantially, the assessed value of the entire grand list rises too.

That generally means a lower mill rate could generate the same amount of tax revenue.

But the town is also establishing a new budget.

If the budget increases, West Hartford needs to collect more money.

Those two forces come together when the Town Council establishes the new mill rate during the 2027 budget process.

Until that happens, taking your new assessed value and multiplying it by the current mill rate will give you a number—but not your actual future tax bill.

Does a higher assessment mean your taxes will rise?

Probably, for many homeowners.

But the amount cannot be determined simply by looking at how much your own assessment increased.

The more useful question is:

Did my property increase in value more or less than West Hartford overall?

Imagine almost every property in town goes up substantially.

If your property increases at approximately the same rate as the overall tax base, your share of that tax base may not change dramatically based on revaluation alone.

But if your neighborhood or property increased significantly faster than the town as a whole, you could end up carrying a larger share of the tax burden.

If your home appreciated more slowly than the town overall, your relative share could potentially decline.

Then the new town budget gets layered on top of that.

This is why two West Hartford homeowners whose assessments both increase can still experience different changes in their eventual tax bills.

Does the new assessment tell you what your house would sell for?

Not exactly.

The assessment and market value are related, but I would not treat the town’s number as a substitute for an individual real estate valuation.

The town is using a mass-appraisal model.

A buyer is walking through your front door.

The buyer notices the kitchen, bathrooms, light, layout, yard, basement, condition and all the things that make your house different from another house a few streets away.

That is why I tell homeowners not to take a high town value as a compliment or a lower one as an insult.

It is a number being created for taxation purposes.

If you were actually selling, your likely market value would be determined by the current comparable sales, current competition and what buyers were willing to pay for your particular property.

What if no one came inside your house?

That does not automatically mean anything went wrong.

A mass revaluation does not require a full interior inspection of every property.

But it does make your property record particularly important.

Take a look at what the town thinks exists.

Does the square footage look correct?

Is the bedroom count right?

How many bathrooms are listed?

Does the town show a finished basement that no longer exists—or fail to show improvements that were made?

Did you remove a deck?

Add a bathroom?

Finish part of the lower level?

The model can only work with the information available to it.

If that information is wrong, the resulting valuation may also deserve a closer look.

When will you actually know your new property taxes?

The important dates occur in stages.

October 1, 2026 is the valuation date.

The revaluation notice is expected later in 2026.

Homeowners who disagree with their values will have an opportunity to question them through the review and appeal process.

The town will then go through its 2027 budget process, and the new mill rate is expected to be established in the spring.

Your first tax bill reflecting both the new assessment and the new mill rate would follow after that.

So when the revaluation notice arrives, you are receiving one important piece of the eventual tax calculation.

You are not receiving your next tax bill.

What should you do when the notice arrives?

Start with the property information.

Make sure the town has the basic facts about your house right.

Then look at the town’s stated market value and ask a practical question:

Could I realistically sell my house for approximately this amount as of October 1, 2026?

Do not answer based on what you wish the value were.

Do not compare it only with your neighbor’s house.

Look at homes that are actually similar in location, size, age, style and condition.

If the number appears reasonable, the fact that you do not like the resulting assessment does not necessarily mean it is inaccurate.

If the town says your property is worth an amount you genuinely believe a buyer would never pay—and you have evidence supporting that conclusion—then it may be worth questioning.

Assessment, market value and taxes are three different conversations

This is the part I most want West Hartford homeowners to remember.

Your new market value is the town’s estimate of what the property was worth as of October 1.

Your assessment is the taxable value derived from that market value.

Your tax bill will eventually depend on the assessment and the new mill rate created through the town budget process.

Do not combine all three into one number when the envelope arrives.

And if what you really want to know is what your home could sell for in the current West Hartford market, that requires a different analysis.

I can look at your property record, the recent comparable sales and what is happening in your specific neighborhood and give you a much better idea of whether the town’s market value appears reasonable.

You do not have to be thinking about selling.

Sometimes understanding the actual value of your house is simply useful information—especially when a very official-looking number is about to show up in your mailbox.
