Seven Connecticut chambers,
side by side

Every figure on this page is taken from a filed IRS Form 990, public record through ProPublica. Nothing here is estimated, modeled or projected. Where a number could not be verified, it is left blank and said so.

Connecticut chambers and chamber foundations examined finished their most recent filed year short.

01

The first thing the filings say

The only one that finished ahead is also the largest.

Running a deficit at this size is what the model produces. It is not a verdict on how any one chamber is run. Every organization below roughly $600,000 in revenue in this set lost money, and they are run by different people in different counties with different boards.

What separates the one that finished ahead is not that it charges members more. It is that most of its money comes from something other than dues.

Result is total revenue less total expenses on the filed return. Blank cells are figures not verified at the time of compiling, not figures assumed to be zero. Northwest Connecticut's return did not resolve under any name searched; its revenue mix below is carried from the same comparison set.

Two years worth looking at twice

Northeastern Connecticut · result
+$21,258
FY 2024
−$43,086
FY 2025
A swing of $64,344 in twelve months. Their 2025 return is filed and public, which makes it the most recent picture available for any chamber in this set.
Granby-Simsbury · total revenue
$164,310
FY 2023
$109,455
FY 2024
Down 33% in one year, against expenses of $151,134 — a deficit of $41,679 on a chamber that took in $109,455.

These two are singled out because they are the only chambers in the set whose most recent filing moves sharply against the prior year. Both are public. Both are recent. Neither is explained by the filing itself.

04

Where the money comes from

Share of total revenue earned from something other than membership dues. This is the line that separates the set more than any other.

Northwest Connecticut, Torrington67.7%
Eastern Connecticut, Waterford65.0%
Granby-Simsbury43.9%
Greater Manchester, Connecticut38.8%
Northeastern Connecticut, Danielson34.5%
Tolland County25.8%
North Central Connecticut, Enfield16.5%

Bars are drawn to scale against 100% of total revenue.

A better mix alone does not guarantee solvency. Northwest earns 67.7% beyond dues and still finished short. But the one chamber in this set that finished ahead sits at 65%, and every chamber below the middle here finished behind.

05

Events and fundraising

The single line with the widest spread across the set, on revenue bases that are far closer together than the results suggest.

Greater Manchester, Connecticut$69,987
Northeastern Connecticut$41,912
Granby-Simsbury$31,850
Tolland County$12,837
North Central Connecticut$0
Filed as zero — revenue reported under programs
Northwest Connecticut$0
Filed as zero — revenue reported under programs

Bars are drawn to scale against the largest figure in the set, $69,987.

Eastern Connecticut does not report this line separately and is left out rather than shown as zero. A $0 here means the line was filed as zero, which in two cases reflects revenue reported under programs instead.

06

What members pay

Four of the seven publish a dues schedule. What the same business would pay, at two different sizes.

At three employees
ChamberAnnual dues
Tolland County$375
Eastern Connecticut$325
Granby-Simsbury$300
Northeastern Connecticut$230

A spread of 63% between the cheapest and dearest entry tier, for organizations recruiting from the same kind of business.

At one hundred employees
ChamberAnnual dues
Granby-Simsbury$825
Eastern Connecticut$810
Tolland County$775
Northeastern Connecticut$750

The order at the top tier is close to flat, and in one case reverses. The spread at the entry tier is 63%; at the top tier it is 10%. Whatever the schedules are pricing, it is not size.

07

What the strongest ones actually run

Section 04 shows who earns beyond dues. It does not show from what. The filings do, and the answer is not that anyone found a clever new idea.

An endorsed member program$871,634 Eastern Connecticut files a member health insurance program on its program revenue line. It is half of that chamber's total revenue, and it is the only chamber in this set that finished the year ahead. Members pay less than they would alone; the chamber earns a share for arranging it.
Economic development contracts$360,975 Northwest Connecticut files program revenue from economic development contracts, a paid leadership program and a careers marketplace. Contracted work, not grant applications.
One real event, run properly$69,987 Greater Manchester earns more on this line than four of the others combined, on a revenue base close to theirs. Northeastern files $41,912 and Granby-Simsbury $31,850 on the same line.

Each figure is that organization's own filed number. Nothing here is a projection of what another chamber would earn from the same activity.

08

What a chamber built out of the best of these would look like

Not an invention. Every line below is a real filed figure achieved by a named chamber in this set. No Connecticut chamber here is doing all of them. Every single one of them is being done by somebody.

Revenue beyond dues67.7%Northwest Connecticut's share. Two of the seven are already above 65%.
An endorsed member program$871,634Eastern Connecticut's line. Scales with the member base and costs almost no staff time per dollar.
Contracted program work$360,975Northwest Connecticut's line. Paid work for towns and the state, not fundraising.
One signature event$69,987Greater Manchester's line. One flagship with a title sponsor, priced from real costs, instead of a calendar of small mixers.
Entry dues that recruit$230Northeastern Connecticut's rate. The cheapest front door of the four that publish, in a state filing over a thousand new businesses a year.
Enough hands to run all of itNobodyNot one organization in this set files this. Every chamber here is one or two people.

That last row is the one that explains the other five.

None of this is secret. Every director in the state knows sponsorship and events and endorsed programs are where the money is. The filings do not show a knowledge problem.

They show a capacity problem. A revenue line like the first three takes months to build, and it has to be built by the same person who is answering the phone, chasing the unpaid dues, posting the events and writing the newsletter. The work that would grow the organization is always the work that gets moved to next week, because everything else has a deadline attached to somebody else.

Which is why the mix does not fix itself, and why every chamber in this set below roughly $600,000 finished the year short. The money problem and the time problem are the same problem, and the time problem comes first.

What this page does not do

It does not say what any of these figures mean for a particular chamber. A 990 shows what came in and what went out. It does not show how many members an organization has, how many hours anything takes, or what any of it was for — and none of those are guessed at here.

Member counts are not published in comparable form, so revenue per member is not calculated anywhere on this page rather than estimated. Two chambers publish no dues schedule at all and are absent from section 06 rather than filled in.

09

Why this was compiled

I do operations work with small chambers in Connecticut. Before saying anything about the sector I wanted to know what it actually files, so I read the returns rather than the press releases. The conclusion in section 08 is where reading them led, and it was not the one I expected to find.

If any of this raises a question about your own numbers, my number is below. Happy to answer it whether or not it goes anywhere.
