Fairfield's Mill Rate Dropped After Revaluation. So Why Are So Many Tax Bills Higher?

Fairfield's mill rate fell by about a third this year, to 19.19. Even so, a home whose value rose about as much as the town average in the 2025 revaluation now owes roughly 11% more in tax than it did last year.

That gap matters to anyone comparing Fairfield with the towns around it. The rate is the figure people quote. What a home costs to carry depends on how much its own assessment rose, and that varied widely from one house to the next.

Start With the Date on the Tax Figure

Before you compare two Fairfield houses, check when each tax number was calculated. Fairfield's revaluation used an October 1, 2025 assessment date, and the town says the new values apply to tax bills beginning in July 2026. Any tax figure dated before that July uses the old assessment and the old rate of 28.39 mills. Neither one still applies.

The town's tax rate page lays out how the bill is calculated. Assessed value is 70% of appraised value, and both numbers are on each property's record card. A mill is a dollar of tax per $1,000 of assessed value. Real estate taxes are due in quarters, on July 1, October 1, January 1 and April 1, according to the tax collector. Sewer use charges come as a separate bill. Bills over $300 are split between October 1 and April 1. So the October 1 installment that just came due is the second payment on the new values. A full year of post-revaluation bills doesn't exist yet.

Fairfield did not appear to phase in the change. The town's notice ties the October 2025 assessment directly to the July 2026 bills, with no multi-year schedule. The whole revaluation landed in a single year.

The Town Raised Only 2% More. Homes Paid a Bigger Share of It.

The budget numbers explain most of what happened. Fairfield's FY2026-27 final budget totals $400,381,928. The tax levy, the total property tax the town bills, rose from $346.08 million to $353.10 million, an increase of 2.03%. Over the same period the mill rate fell 32.41%, from 28.39 to 19.19.

A 2% larger tax bill for the whole town turned into much larger increases for many homeowners because property values didn't rise evenly. The town reported residential values up 63.88% in the revaluation and commercial values up 16.61%. Homes' projected share of the Grand List grew from 78% to 84%. A later budget presentation from April 6, 2026 put the figures at 63.74% for residential and 19.33% for commercial. Either way, homes now carry a larger share of a slightly larger total.

That's why the rate cut doesn't show up in many bills. A lower mill rate spreads the same tax total across a larger pool of assessed value. The cut only offsets the revaluation for properties whose values rose by less than everyone else's.

Where the Break-Even Sits

Divide the old rate by the new one and you get about 1.48. A Fairfield home whose assessment rose roughly 48% pays about the same tax as before. A home that rose more pays more, and a home that rose less pays less. The town average was about 64%, so the typical house landed well above break-even.

The table below uses those two mill rates to show the math. It covers only the real estate tax and doesn't account for appeal outcomes.

For a hypothetical home appraised at $1,000,000 before the revaluation, the assessment would have been $700,000. At 28.39 mills, that's a bill of about $19,873. If its value rose 64% to $1,640,000, the new assessment is $1,148,000. At 19.19 mills the bill becomes about $22,030, roughly $2,150 more.

Public estimates from officials have been in the same range. Connecticut Public reported that State Rep. Sarah Keitt, who represents Fairfield and Trumbull, said property owners "could see an increase in property taxes of 8% but that's way below what their revaluations may have indicated." When the Board of Finance set the rate, Patch reported that board member Jim Walsh questioned how much the lower rate really meant, since many homeowners would still face substantially higher bills. Tax Collector David Kluczwski urged caution on collection assumptions, citing the significant increase many homeowners would see.

The Appeals Season Changed Assessments House by House

The town average describes no particular house, and the appeals proved it. CT Insider reported that 884 homeowners had filed with the Board of Assessment Appeals by late May 2026. Several of the residential properties assessed above $15 million are on Sasco Hill Road.

Patch's report from the June Board of Finance meeting gives the outcome. Assessor Ross Murray said the board heard and decided 876 appeals, up from 619 after the 2020 revaluation. Of those, 78% ended in a reduction, a share he called normal, compared with 77% the year before. The difference this time was size. The average reduction was about 17%, compared with about 3% in 2020.

For a buyer, that changes how you use comparables. Two similar houses on the same street can now carry noticeably different assessments, depending on whether one owner appealed and how the appeal turned out. A neighbor's tax bill tells you very little about the house you're looking at. Its own property card, updated after the appeals, tells you much more.

Why Mill Rates Mislead Across Town Lines

Fairfield's 19.19 now looks low next to some neighbors and high next to others. Part of that is budgets. Part of it is timing. Connecticut towns revalue on staggered five-year cycles, so in any given year some towns are taxing on fresh values and others on values set years earlier. The state's mill rate dataset and the OPM revaluation schedule show how far apart nearby towns sit.

Stamford sets separate residential rates by tax district, from 24.31 to 25.14 mills, according to a Board of Finance resolution dated May 21, 2026. The state schedule also has Stamford due for revaluation in 2027.

Westport shows the same pattern as Fairfield. Its rate fell from 18.86 to 13.2 after a revaluation that raised residential assessments about 60%, and the Westport Journal noted that many homeowners still face higher bills. CT Insider reported that Westport's appeals board cut 136 of 305 residential assessments.

Towns due in 2027 are taxing on values set before recent price gains. When they revalue, their rates will likely move the way Fairfield's and Westport's did. A rate gap that looks wide today can shrink once every town is valued in the same market. To compare carrying costs, look at a specific home's assessment and the current rate in its town, and keep in mind when that town revalues next.

Quick Answers

Does the lower mill rate mean Fairfield taxes went down? For the town as a whole, the tax levy rose 2.03% for FY2026-27. For an individual home, it depends on how much its assessment rose compared with roughly 48%.

Where can I see a Fairfield home's current assessment? On the property record card linked from the assessor's office. It shows both the appraised value and the assessed value, which is 70% of the appraised value.

When is Fairfield's next revaluation? The state schedule lists 2030 for both Fairfield and Westport.

Did the appeals change the town's numbers? Yes. The budget's Grand List figures were adjusted after the Board of Assessment Appeals finished, and Patch reported an average assessment reduction of about 17% this cycle.

If you're weighing a Fairfield home against one in Westport, Weston or Wilton, the tax line deserves as much attention as the list price.
