Fairfield's Board of Finance voted unanimously on June 2 to set the 2026-27 mill rate at 19.19. The year before, it was 28.39. A buyer comparing towns could read that as a one-third tax cut. Patch's coverage of the vote reported the opposite for many households: most homeowners will still pay more, because the town's revaluation found that home values had climbed over the previous five years.
When you're buying, this is where the risk sits. The mill rate is a townwide number. The tax bill belongs to one house. Since the October 1, 2025 revaluation, those two numbers say less about each other than they used to.
Start with the tax figure on the listing
New assessments first showed up on the July 2026 tax bill. Any annual tax figure you see for a Fairfield house falls into one of two eras: the old assessment at 28.39 mills, or the new assessment at 19.19. Before you put a tax number into a monthly budget, check which era it comes from.
- Find the final assessment. The town has posted final values on its Vision Government Solutions property site, along with PDF field cards. The town also tells owners to use the final value, not the one on the first notice.
- Multiply by the current rate. The Town of Fairfield says assessed value is 70% of market value. At 19.19 mills, every $100,000 of assessed value comes to $1,919 a year in tax before exemptions.
- Compare the result to the listing. If the listing's figure is well below your result, it may reflect the 2025-26 bill. If it's above, the house may have won an appeal or carry an exemption. The assessor's records will tell you which.
Exemptions can change the math too. The town doubled most veteran exemptions this cycle. The basic one went from a $12,000 assessment reduction to $24,000, starting with the July 2026 bill.
The break-even point is roughly a 48 percent assessment increase
Dividing the old rate by the new one gives 28.39 ÷ 19.19, or about 1.48. A house whose assessment rose by less than about 48% should see a lower bill at 19.19 than it had at 28.39. A house whose assessment rose by more than that should see a higher one. Everything else in Fairfield's tax story follows from that threshold.
The town's revaluation materials show which side of it most homes landed on. Town estimates put the rise in residential values at about 63.88%, commercial at about 16.61%, and all real estate combined at 57.52%. The town labels these as estimates, not final figures. Run those estimates through the break-even math:
| Property class | Town's estimated value change | Bill change if the assessment moved exactly with the estimate |
|---|---|---|
| Residential | about +63.88% | roughly 11% higher |
| Commercial | about +16.61% | roughly 21% lower |
| All real estate combined | +57.52% | roughly 6% higher |
These bill changes are just arithmetic on the town's estimates. They leave out budget details, appeals and exemptions, and no single house moved exactly with its class average. They still show the direction clearly. Here's an example: a house with a $700,000 assessment today, which matches $1,000,000 in market value, owes about $13,433 at 19.19. If that assessment had risen 63.88%, it was about $427,000 before, and the old bill at 28.39 would have been about $12,127.
Why homes picked up a bigger share
The assessor's office put it plainly. Most homeowners will pay more because residential values rose faster than commercial values. That pushed residential property up from 78% of the Grand List to a projected 84%. The town calls this a "shift," meaning homeowners carry a larger share of the total tax. The town also noted that home values jumped in the 2020 revaluation, but commercial values kept pace that time. This cycle, they didn't.
The budget adds to the effect. The first selectperson's FY27 budget proposal carried a 4.28% gross tax levy increase, and the RTM approved a $400 million town budget for 2026-27. The town warned during the revaluation that any drop in the mill rate would be partly offset by a bigger budget.
All of this matters if you're comparing towns by mill rate. A town's rate reflects its own Grand List, its own budget and its own revaluation timing. Patch's June coverage also pointed to Westport, where the Board of Finance set a 13.2 mill rate as its own revaluation shifted the tax burden. Comparing two towns' rates won't tell you how two houses' bills compare. You need each house's assessment.
876 appeals made assessments a house-by-house question
If the same revaluation set every assessment, you could estimate taxes from the price alone. The appeal numbers show why that doesn't work this cycle. Assessor Ross Murray told the Board of Finance that the Board of Assessment Appeals heard and decided 876 appeals this cycle, up from 619 after the 2020 revaluation. Seventy-eight percent of appeals ended in a reduction. The average reduction was roughly 17%, compared with about 3% in 2020.
Board members read those numbers differently. Board member Jim Walsh argued that many homeowners still face much higher bills despite the lower rate, and he criticized the revaluation process. Board Chair Craig Curley responded that the appeals process worked as intended, and that an unusually large jump in residential values likely drove the volume. Murray said the share of appeals winning reductions wasn't historically unusual. "What makes the number large is the sheer number of appeals," he said.
For a buyer, the practical takeaway doesn't depend on who's right. Hundreds of Fairfield houses now carry assessments that were cut after the first notice, and an average cut of about 17% is large. Two homes at similar prices on the same street can now have noticeably different tax bills, depending on whether the owner appealed. The field card shows you which case you're looking at.
What 19.19 means at today's prices
SmartMLS figures for August 2026 put Fairfield's single-family median sale price at $1,182,500, across 60 closings. The median was down 9.7% and closings were down 9.1% from August 2025. The year-to-date median through August was $1,175,000, up 6.8%, on 394 closings.
Under the town's 70% rule, a house assessed in line with that August median would have an assessment of about $827,750. At 19.19 mills, that's roughly $15,885 a year before exemptions. The town is clear that a house's assessment and its sale price are different numbers, so the actual bill on a given house could be higher or lower.
The market isn't giving buyers much time to sort this out. In August 2026, Fairfield's single-family homes averaged 27 days on market, with 103 homes in inventory and 2.1 months of supply. Pull the assessment before you write an offer, not after.
Who pays which bill at closing
The Town of Fairfield bills real estate taxes in four installments, due July 1, October 1, January 1 and April 1. The October installment came due three days ago. A buyer closing this fall is stepping into a fiscal year that's already billed at the new assessment and the 19.19 rate.
Under the Fairfield County Bar Association's closing customs, real estate taxes are adjusted as of the closing date unless buyer and seller agree otherwise. The customs set the fiscal year as July 1 through June 30, and taxes assessed on the preceding October 1 list apply to the fiscal year that follows. Adjustments use a 365-day year and the actual days in each month. The buyer is treated as the owner on the closing day, and the seller's share runs through the day before. These customs can be overridden by the purchase contract. Your closing attorney will confirm which list year and which installments are being prorated. This year, that check counts for more than usual.
FAQ
Does a lower mill rate mean Fairfield taxes went down?
For most homes, no. The rate fell about 32%, but the town estimated that residential values rose about 63.88%. Once a home's assessment rose more than about 48%, its bill went up.
Is the next appeal deadline set?
Yes. Appeals of the 2026 Grand List are due to the Board of Assessment Appeals by Friday, February 19, 2027, at 4:30 p.m. Filing details are on the town's Board of Assessment Appeals page.
Where do I confirm a specific house's assessment?
Go to the town's 2025 Property Revaluation page and the linked Vision Government Solutions site, which carries final values and field cards. This post explains how the numbers work. It isn't tax or legal advice, so confirm figures with the assessor's office and your attorney.
