Property taxes can be confusing when the number that determines your bill changes, but the bill itself doesn’t necessarily move in the same direction. That’s especially true in Fairfield after the town’s 2025 property revaluation. The Fairfield CT mill rate for 2026 is 19.19, down from 28.39 in 2025, but that doesn’t mean every homeowner will see a lower tax bill.
What matters is how the new rate impacts your home’s updated assessed value. In this guide, we’ll look at what 19.19 mills means in actual dollars, how the revaluation affects different properties, and how Fairfield’s tax burden compares with nearby towns such as Westport, Trumbull, and Norwalk.

Fairfield CT Mill Rate in 2026: What Homeowners Need to Know
The rate change is the biggest Fairfield has seen in years, and it caught many residents off guard.
What Is Fairfield’s Current Mill Rate?
19.19 is the number for the fiscal year running July 1, 2026, through June 30, 2027, approved by the Board of Finance after weeks of budget hearings. It applies to real estate, personal property, and motor vehicles across town, with real estate taxed at the full rate against its assessed value.
Why Fairfield’s Mill Rate Changed for 2026
Fairfield’s grand list, the total assessed value of everything taxable in town, grew a lot heading into this budget cycle. State law requires periodic revaluations, and Fairfield’s landed for the October 1, 2025 grand list. Fairfield home values climbed roughly 65% across town during the years that revaluation captured. When the base a town taxes against grows that much, the rate needed to raise the same revenue drops accordingly.
How Fairfield’s Mill Rate Compares With Previous Years
Before the revaluation, Fairfield’s mill rate had been trending upward for years, reaching 28.39 for 2025-26. The drop to 19.19 looks dramatic on its own, but the rate is now being applied to much higher property assessments. That makes a straight comparison with older rates misleading. What really matters is how the change affects your projected tax bill.
| A lower mill rate after a revaluation isn’t the town cutting your taxes. It’s the rate adjusting to a bigger tax base. What happens to your own bill comes down to how your property’s assessment moved compared to everyone else’s. |
How Fairfield CT Property Taxes Are Calculated
The mill rate is only half the equation. You need your assessed value too, and Connecticut calculates that a specific way.
What Is a Mill Rate in Connecticut?
One mill equals $1 of tax per $1,000 of assessed value. At 19.19 mills, you owe $19.19 for every $1,000 your property is assessed at. Each municipality sets its own rate annually based on its budget and grand list size, according to the state Office of Policy and Management.
The 70% Assessment Rule for Connecticut Properties
Connecticut doesn’t tax homes at full market value. State law caps the assessment at 70% of fair market value as of a revaluation. A home appraised at $500,000 gets assessed at $350,000, and that lower figure, not the sale price, is what gets multiplied by the mill rate. Fairfield’s Assessor’s Office confirms this ratio applies town-wide across Connecticut property taxes by town.
The Simple Formula for Calculating Property Tax
Take your home’s market value, multiply by 0.70, divide by 1,000, then multiply by the mill rate. A $500,000 Fairfield home comes out to $350,000 assessed, times 19.19, for an annual bill near $6,716.50.

Fairfield CT Property Tax Examples for 2026
Here’s what 19.19 mills actually costs at three common price points.
Property Tax on a $500,000 Fairfield Home
Assessed at $350,000, this home owes roughly $6,716.50 a year, about $560 a month if you’re folding it into an escrow payment.
Property Tax on a $750,000 Fairfield Home
Assessed at $525,000, the estimated annual bill lands at $10,074.75, close to $840 monthly.
Property Tax on a $1 Million Fairfield Home
The easiest way to see what the 19.19-mill rate means for your budget is to look at a few different home values. Assuming the standard 70% assessment, here’s what the estimated annual property tax looks like at three common price points:
| Home Value | Assessed Value (70%) | Est. Annual Tax at 19.19 Mills |
| $500,000 | $350,000 | $6,716.50 |
| $750,000 | $525,000 | $10,074.75 |
| $1,000,000 | $700,000 | $13,433.00 |
These figures give you a useful starting point, but your actual bill may be different. The final amount depends on your property’s assessed value and any exemptions or adjustments that apply to your situation.
Why Your Actual Tax Bill May Be Different
These are estimates built on the townwide rate and the standard 70% ratio. Your real bill hinges on your property’s actual assessed value, any exemptions you qualify for, and whether your home’s assessment moved more or less than the townwide average. Confirm exact figures with Fairfield’s Tax Assessor before you build a budget around any estimate.
Fairfield’s 2025 Revaluation: What Changed for Homeowners?
The revaluation is the reason this year looks so different from last. Worth understanding on its own.
Why Fairfield Revalued Properties
Connecticut requires towns to periodically revalue all taxable property so assessments track actual market conditions. Fairfield’s revaluation wasn’t optional or discretionary. It ran on the state-mandated schedule, effective for the October 1, 2025 grand list.
How Revaluation Affects Assessed Values
The town’s contracted appraisal firm reassessed every property and applied the standard 70% ratio to current fair market value. Since Fairfield home values rose substantially heading into 2025, most residential assessments went up, some by a lot more than others depending on the property.
Why a Lower Mill Rate Does Not Automatically Mean Lower Taxes
Here’s where people get tripped up. If your assessment rose in line with the townwide average, the lower mill rate roughly cancels that out, and your bill stays close to flat. If your assessment jumped faster than average, expect a higher bill even with the reduced rate. The two numbers move together. Neither one tells the whole story alone.
What the 2026 Revaluation Results Mean
19.19 mills reflects both the completed revaluation and the budget the Board of Finance approved for 2026-27. Board members publicly questioned the revaluation’s accuracy during that meeting, pointing to how many assessment appeals had succeeded, which suggests a real number of homeowners felt their initial numbers were off.
Why Fairfield Homeowners May Still See Higher Tax Bills
Rate’s down. Plenty of residents are still bracing for a bigger bill. Here’s why those two facts coexist.
The Relationship Between Home Values and Taxes
Two things drive your bill: assessed value and mill rate. One fell, the other rose for most properties, and which effect wins depends entirely on the size of each change for that specific home.
How Your Property’s Assessment Matters
Take two neighbors with similarly priced homes before the revaluation. Afterward, their bills could look completely different if one property appreciated faster than the other. Above-average appreciation likely means a higher bill despite the lower rate. Below-average appreciation could mean a decrease.
Why Some Tax Bills Rise More Than Others
Location, lot size, recent renovations, condition- all of it factors into how much an individual Fairfield, CT property’s tax assessment shifted. Board of Finance members noted the impact could range anywhere from a modest decrease to a steep increase, purely based on how that one property was revalued.
Fairfield Property Tax Appeals: What Homeowners Should Know
Think your new assessment is out of line with what comparable homes are actually selling for? You have a formal way to push back.
When Can You Challenge an Assessment?
Homeowners who believe their property was over-assessed can file a written appeal with the Board of Assessment Appeals. Following a revaluation year, the appeal window typically opens in early February, with applications due by mid to late February ahead of March hearings.
How the Property Tax Appeal Process Works
You start with a written application to the Assessor’s Office, including your own estimate of value and your reason for appealing. The board schedules a hearing, you bring evidence like comparable sales, and they issue a written decision afterward. Under Connecticut General Statutes, the board can raise, lower, or leave an assessment unchanged.
Why Recent Fairfield Appeals Matter in 2026
A notably high number of Fairfield homeowners appealed after the 2025 revaluation, enough that it became a talking point at the Board of Finance’s own mill rate meeting. That’s a good reason to check your own assessment closely rather than assume it came out right.
Fairfield CT Mill Rate vs. Other Connecticut Towns
Fairfield isn’t operating in isolation. Nearby towns went through their own revaluations around the same time, with wildly different outcomes.
Fairfield vs. Westport Property Taxes
Westport set its 2026-27 rate at 13.2, down from 18.86, after its grand list grew more than 50%. On a $750,000 home, that’s about $6,930 a year in Westport versus $10,074.75 in Fairfield, a real gap even though both towns just went through revaluations.
Fairfield vs. Trumbull Property Taxes
Trumbull went the other direction. Its Board of Finance set 2026-27 at 37.42 mills, a 1.73% increase driven mostly by rising healthcare costs rather than a revaluation reset. The same $750,000 home in Trumbull runs about $19,645.50 a year, nearly double Fairfield’s number.
| A town with a high mill rate isn’t automatically more expensive to own in, and a low one isn’t automatically cheaper. The rate only means something once you pair it with that town’s assessed values, which is why two towns with a 20-mill gap between them can end up with nearly identical tax bills on comparable homes. |
Fairfield vs. Norwalk Property Taxes
Norwalk is harder to compare head-to-head. The city applies different rates across six separate taxing districts, and its last revaluation was back in 2023, two years ahead of Fairfield’s. Norwalk’s Board of Estimate and Taxation approved roughly 3% increases across those districts for 2026-27, smaller than originally proposed but still an increase, the opposite direction of Fairfield’s post-revaluation drop.
Why You Shouldn’t Compare Mill Rates Alone
A mill rate by itself tells you almost nothing unless you also know the assessment ratio and where a property sits in its own revaluation cycle. Comparing homes in the Fairfield real estate market against a similarly priced home somewhere else means running the full calculation for both, not just eyeballing the headline number.
What Fairfield Property Taxes Mean for Home Buyers and Sellers
Property taxes aren’t a one-time cost. They belong in the budget conversation from day one, right alongside the mortgage.
How Property Taxes Can Affect a Buyer’s Budget
Two similarly priced homes in different towns can end up hundreds of dollars apart on monthly payments once taxes enter the picture. Shopping Fairfield CT real estate means checking the current mill rate against your price range before you get attached to a specific house.
How Taxes Can Influence Fairfield Home Values
Buyers increasingly weigh total cost of ownership, not just the sticker price. That means the shift in Fairfield CT property values from the 2025 revaluation can shape demand right alongside the mill rate, since both determine what a home actually costs to hold onto.
What Sellers Should Know Before Listing a Fairfield Home
Be ready to answer questions about the new assessment and rate. Buyers who’ve done their homework will ask. Pricing accurately against the current tax environment, rather than last year’s numbers, heads off surprises during negotiations or appraisal for anyone listing Fairfield CT homes for sale.

How to Estimate Your Fairfield CT Property Tax Bill
It is always advised to go with a number specific to your own house. Here’s the process.
Find Your Property’s Assessed Value
Your assessed value is a public record, available through Fairfield’s Assessor’s Office or its online property lookup. That’s the figure from the 2025 revaluation, not your home’s list price or a recent private appraisal.
Apply the Fairfield CT Mill Rate
Divide your assessed value by 1,000, then multiply by 19.19. That’s your estimated base annual tax before exemptions.
Account for Any Applicable District Charges or Adjustments
Some properties carry extra charges beyond the townwide rate, and exemptions for veterans or elderly homeowners can lower the final number. Check with the Assessor’s Office to see if any apply to you before locking in a budget estimate.
Fairfield CT Real Estate and Property Taxes in 2026
Taxes are one piece of a bigger picture if you’re actively house hunting or getting ready to sell.
What Buyers Should Check Before Purchasing in Fairfield
Confirm the current assessed value before making an offer, and run the tax math yourself instead of trusting a listing’s estimate, which can lag behind reality. This is where local Fairfield CT real estate expertise earns its keep, since pricing and tax context shift with every revaluation cycle.
How Property Taxes Factor Into a Fairfield Home’s Overall Cost
Taxes are often one of the highest recurring costs of owning here, sometimes rivaling insurance and maintenance combined. Build the 2026 mill rate into your affordability math up front so nothing surprises you after closing.
Why Local Real Estate Knowledge Matters
In my practice, I’ve found buyers who understand a town’s tax trajectory, not just its current rate, make offers with more confidence. Making sense of the Fairfield homes and local market after a revaluation year takes more than skimming listing prices, since values and taxes are shifting together right now.
Understanding Fairfield CT Property Taxes in 2026
Although the mill rate dropped to 19.19, your actual tax bill depends on your home’s 2025 revaluation. Some homeowners will pay less, while others will pay more. Calculate your specific numbers rather than relying on the headline rate.
Whether you are budgeting for your current home or considering a purchase, I can help you understand your property’s tax impact.

FAQs
19.19, set by the Board of Finance in June 2026 for the fiscal year beginning July 1. That’s down from 28.39 the year before, following the town’s 2025 property revaluation.
It depends on the home, but a $500,000 property assessed at 70% of that value owes roughly $6,716.50 a year at the current rate. Higher-value homes scale up from there, with a $1 million home landing closer to $13,433 annually.
Multiply your home’s market value by 0.70 to get the assessed value, divide that by 1,000, then multiply by the mill rate of 19.19. Your exact assessed value is on record with Fairfield’s Assessor’s Office if you want to skip the estimate and use the real number.
A 2025 town-wide revaluation significantly increased Fairfield’s total assessed property value, with average residential assessments rising roughly 65%. When the grand list grows that much, the town can raise the same revenue with a much lower rate.
Not necessarily. Your actual bill depends on how your own property’s assessed value changed relative to the townwide average, so a home that appreciated faster than most could still see an increase.
Most residential assessments rose across town, some considerably more than others depending on the property, which prompted the mill rate to drop and offset the larger tax base. The revaluation also triggered a notably high number of assessment appeals from homeowners who felt their new numbers were too high.
For the 2026–2027 fiscal year, Fairfield is positioned between Westport’s 13.2 and Trumbull’s 37.42 mills, at 19.19 mills. Because Norwalk has six distinct taxing districts instead of a single townwide rate, it is more difficult to place it on the same scale.
Many buyers still find Fairfield worthwhile for its location and range of housing options, even with property taxes factored into the total cost. The key is running the actual numbers for a specific home before making an offer, rather than relying on the townwide rate alone.
