Fairfield's Board of Finance voted unanimously in June to set the fiscal 2026-27 mill rate at 19.19, down from 28.39 the year before. The approved budget puts that at a 32.41% decrease. At the same meeting, the town expected that many homeowners would see their property taxes go up.
Both are true because of the 2025 revaluation, and the revaluation changes what a buyer should look at. In Fairfield this fiscal year, the mill rate tells you very little about any one house. What matters is how much that particular house's value rose between the 2020 and 2025 revaluations. Most of the time, that is not something a buyer can see from the asking price.
Last Year's Tax Figure Was Calculated On A Different House
This is where buyers comparing towns run into trouble. A Fairfield tax figure from the fiscal year that ended June 30, 2026 combined two numbers that no longer apply. It used the 28.39 rate and an assessment from the October 1, 2024 Grand List. This year's bills use 19.19 mills on the October 1, 2025 assessment. The town mailed the first bills under the new values on June 25, 2026. They were due July 1, and August 3 was the last day to pay without interest.
So any number taken from the earlier cycle reflects a house the town has since revalued. Applying the new, lower rate to the old assessment makes the property look much cheaper to carry than it is. Keeping the old rate and old assessment together gives last year's bill, which could be higher or lower than this year's depending on the house.
The current assessment is public. The Town of Fairfield posts final values and field cards on its Vision Government Solutions property record site. Multiply that assessment by 19.19 and divide by 1,000 to get this year's real estate tax.
The Rate Dropped Because The Base Underneath It Grew
A revaluation is meant to be revenue neutral. The total the town needs to collect stays roughly the same, and what shifts is each taxpayer's share. Fairfield's numbers fit that. Between the two budgets, property available for assessment rose from $12.189 billion to $18.397 billion, up 50.93%. The current-year levy rose only 2.03%, from $346.077 million to $353.104 million. When the base grows by half and the levy barely moves, the rate has to drop by about a third.
What shifted was who carries the levy. The town's published revaluation estimates show residential values up about 63.88%, commercial values up about 16.61%, and all real estate together up 57.52%. The town labels these as estimates, not final figures. Because homes gained so much faster than commercial property, the town projected that residential property would grow from 78% of the Grand List to 84%. The assessor's page calls this a "shift," with homeowners carrying a larger share of total taxes.
The town also points out how this cycle differs from the last one. Home values jumped in the 2020 revaluation too, but commercial values kept pace then. This time they did not. That gap explains why the lower rate did not lead to lower bills for most homes.
The Break-Even Is Roughly 48 Percent
The math is simple. Divide the old rate by the new one: 28.39 ÷ 19.19 comes to about 1.48. If a property's assessment rose by less than about 48% in the revaluation, its tax bill went down. If it rose by more, the bill went up. The 57.52% all-real-estate figure and the 63.88% residential estimate are both above that line.
The table uses the town's own formula. Assessment is 70% of market value, and the tax is the assessment times the mill rate divided by 1,000. The example is a hypothetical home with a $700,000 assessment under the prior Grand List, which corresponds to a $1,000,000 market value. Only the rate of appreciation changes from row to row.
| Change in the home's assessed value | Tax at 28.39 mills on the old assessment | Tax at 19.19 mills on the new assessment | Change in the bill |
|---|---|---|---|
| +16.61%, the commercial estimate | $19,873 | $15,664 | about −21% |
| +30% | $19,873 | $17,463 | about −12% |
| +48% | $19,873 | $19,881 | roughly flat |
| +57.52%, all real estate | $19,873 | $21,160 | about +6% |
| +63.88%, the residential estimate | $19,873 | $22,014 | about +11% |
| +80% | $19,873 | $24,180 | about +22% |
The table is arithmetic, not a forecast for any address. A home that tracked the residential average pays about a tenth more than it did. A home whose assessment rose 80% pays about a fifth more, under the same rate. The mill rate is the same for every property in town, so it can't tell these two houses apart. The size of each one's revaluation can.
This is also why comparing mill rates across towns is misleading this year. Westport went through its own revaluation, and Patch reported its Board of Finance setting a 13.2 mill rate as that revaluation shifted the tax burden. A rate quoted without the assessment it applies to doesn't say much about what a house costs to own.
Similar Houses, Different Assessments
The appeals record shows how much individual assessments moved after the first notices. Assessor Ross Murray told the Board of Finance that the Board of Assessment Appeals heard and decided 876 appeals this cycle, compared with 619 in the 2020 revaluation. About 78% ended in reductions. The average reduction was roughly 17%, compared with about 3% in 2020.
"What makes the number large is the sheer number of appeals." — Assessor Ross Murray, to the Fairfield Board of Finance
Murray said the share of appeals winning reductions was not unusual historically. He cited 77%, 71% and 81% in the three prior years. Board member Jim Walsh read the results more critically and called the outcome "a 100 percent failure of the revaluation." Board Chair Craig Curley disagreed. He said the appeal process worked as intended and that the unusually large rise in residential values likely drove the volume. Several members suggested a postmortem review. Murray said later analysis would be appropriate but that current market conditions are unusual and hard to compare with earlier cycles.
This matters to a buyer whatever the board concludes. A 17% average cut on hundreds of properties means two similar houses on the same street can carry noticeably different assessments, depending on whether an owner appealed and how the appeal turned out. Those differences carry forward into every quarterly bill. A house's assessment is a fact about that house's history, and it needs to be checked one property at a time.
What The Purchase Price Does Not Change
Many relocating buyers expect that buying a house resets its tax. In Connecticut, it does not. Under CGS §12-63d, a town cannot change an assessment based only on a sale price. Assessments set by a revaluation generally stay in place until the next one, though the statutes do recognize a town's authority to do an interim revaluation in some cases. Fairfield revalues every five years. In practice, a buyer usually takes over the October 2025 valuation as it stands.
The other side of that is useful. The appraised value on the town's property card is the assessment divided by 0.70, and that figure, not the contract price, is what the tax is calculated on. If a buyer pays more than the town's appraised value, the tax still follows the appraisal. If a buyer pays less, the tax still follows the appraisal too.
Fairfield's billing schedule also affects closing. Real estate taxes are due in four installments, on July 1, October 1, January 1 and April 1. The second installment of this fiscal year came due this week. After the grace period, interest starts at 3% and increases by 1.5% per month, and a partial month counts as a full month. The settlement attorney usually prorates the current year's tax by the sale date. The seller pays for the period they owned the house and the buyer pays from the sale date on. The Tax Office asks to be told about the sale so it can bill the new owner for the rest of the year.
Before making an offer on a Fairfield house this fiscal year, a buyer can confirm the following:
- The current assessment on the Town's property record card, multiplied by 19.19 and divided by 1,000.
- How that assessment compares with the prior one, so you know which side of the 48% break-even the house falls on.
- Whether the owner appealed to the Board of Assessment Appeals this cycle and what the result was.
- Which quarterly installments have been paid as of the expected closing date, so the proration matches the town's records.
Short Answers
Is the 19.19 mill rate final? Yes. The Board of Finance adopted it for the fiscal year running July 1, 2026 through June 30, 2027.
Are the 63.88% and 16.61% figures final? No. The town's revaluation page labels them estimates. The final figures are the Grand List totals and the individual assessments on each property card.
Did car owners come out ahead? For most, yes. The town expected most vehicle taxes to go down, because vehicles 15 years old or newer depreciate an additional 5% and are taxed at the lower rate.
Has anyone reported actual July 2026 bill changes? No reporting with actual household figures after the bills went out turned up. The June coverage described expected increases before the bills were mailed. Tax Collector David Kluczwski said at the time that larger bills could lead some taxpayers to delay portions of their payments.
For buyers coming from Manhattan or another Fairfield County town, the yearly cost of a Fairfield house now depends on a figure set in October 2025 and checked one address at a time.
