How Connecticut Municipalities Adopt and Fund Their Budgets

Connecticut municipalities are racing to lock in their fiscal year 2027 budgets even as Gov. Ned Lamont and the General Assembly scramble to pass a state spending plan before the May 6 adjournment deadline, and the gap between how Hartford funds itself versus how Greenwich funds its schools has rarely felt more stark.

The timing mismatch matters. Cities and towns typically adopt their budgets in April or May, well before the July 1 start of the new fiscal year, but they’re making those decisions without knowing exactly how much state aid they’ll receive. That’s a serious planning problem for communities that depend heavily on Hartford’s grants.

How local budgets actually get built

The process starts early in the calendar year. A mayor, first selectman, or town manager puts together a proposed budget for general operations, while the superintendent of schools drafts a separate plan for education spending. Those documents then move to a board of selectmen, a finance board, a city council, or some combination, depending on local charter.

Final adoption varies by town. Some communities hand that authority to a representative town meeting or a council. Others send the budget directly to voters, either through an open town meeting or a formal referendum. Either way, most towns are aiming to finish by late May.

One tax to run it all

Here’s where Connecticut’s municipal finance model gets interesting, and contentious. Unlike the state budget, which draws from income taxes, sales taxes, business taxes, utility charges, and inheritance levies, local governments in Connecticut are authorized to raise money in essentially one way: property taxes.

More than 70% of the average local budget comes from taxes on land, homes, commercial buildings, business equipment, and motor vehicles, according to the Connecticut Conference of Municipalities. Local governments assess properties at 70% of fair market value, then apply a mill rate. One mill generates $1 in taxes for every $1,000 of assessed value. An owner of a home assessed at $400,000 in a town running a 30-mill rate owes $12,000 in annual property taxes. The state caps the motor vehicle tax rate at 32.46 mills.

Nearly all the remaining revenue comes from state grants, with a significantly larger share directed toward lower-income communities. The state sends municipalities more than $3 billion in statutory grants each year, and roughly 70% of that money is tied to education, as CT Mirror has reported on this budget cycle. Additional grants cover road and bridge repairs, capital improvements, and general government costs.

The fairness fight

The property tax system has critics across the political spectrum, and it’s not hard to see why. Mill rates don’t adjust for the property owner’s income or wealth. A retired schoolteacher in a modest New Haven triple-decker and a hedge fund partner in a Greenwich estate both get a flat-rate bill tied to assessed value, full stop.

Many municipal leaders and state legislators have argued that this structure disproportionately burdens middle-class and lower-income households. “Property taxes are the most regressive way to fund local government,” New Haven Mayor Justin Elicker told CT Mirror earlier this year. The complaint isn’t new, but it gets louder every spring budget season.

The disparity shows up starkly between Connecticut’s wealthiest and poorest communities. Greenwich can run a relatively low mill rate and still generate enormous tax revenue because its property values are among the highest in the country. Bridgeport, Hartford, and New Haven carry some of the highest mill rates in the state, yet still can’t generate enough local revenue to adequately fund their schools without heavy reliance on state aid. That dependence makes their budgets especially vulnerable when the General Assembly delays its own spending plan, as it has again this spring.

What to watch before July 1

The state budget deadline of May 6 is the immediate pressure point. If Lamont and legislative leaders don’t reach a deal, municipalities don’t get clarity on their aid allocations, and some towns may have to adopt contingency budgets or revise mill rates after the fact.

The Connecticut General Assembly’s appropriations page tracks the budget timeline in real time. Towns that hold budget referendums in late May are particularly exposed to last-minute changes in state aid figures, and local finance directors in several Fairfield County communities said they’re monitoring Hartford closely before setting final mill rates for fiscal year 2027.
