What a Prop 2½ Override Actually Does

Proposition 2½, passed by the voters in 1980, does two things. It caps how much a city or town can raise from property taxes each year, by 2.5% over the previous year's levy limit, plus the value of new construction, and it requires a vote of the people before a town can go above that cap.

What it does not do is cap your individual bill. Your assessment can rise faster than 2.5% if your home's value rises faster than your neighbors'. Prop 2½ caps the town's total, and the assessor divides that total among properties.

Permanent, or Temporary? That's the Whole Question

Every Prop 2½ question on a ballot is one of three things, and the difference is whether the increase is baked into the base forever or disappears when a project is paid for.

On the ballot	What it does	How long it lasts
Override	Permanently raises the town's levy limit, usually to fund the operating budget, meaning schools, staffing, and services.	Forever. It becomes the new base, and the 2.5% cap applies to the higher number from then on.
Debt exclusion	Raises taxes above the limit only to pay the annual debt service on a specific borrowing, a school, a fire station, a water or sewer project.	Until the bond is paid off, typically 10 to 20 years, then it drops off.
Capital expenditure exclusion	Raises taxes above the limit for a specific capital project paid out of the operating budget rather than borrowed.	A set term tied to the project, then it drops off.

There's also the reverse of an override, an underride, which permanently lowers the limit. They're rare, and they're also decided at the ballot.

What to Check Before You Vote

• What's the dollar impact on an average house? Towns must state the purpose and the amount of the question, and the estimated impact on a typical single-family bill is published in the ballot materials and at the town's information session. Ask for it in dollars, not percentages.
• Is new growth already paying for this? A town's levy limit rises each year by the value of new construction. Ask what this year's new-growth figure is, and whether it's already earmarked.
• If it's an override, will it recur? Permanent overrides sometimes come with a plan to phase in, or a stated term. A phase-in doesn't make it temporary, check the wording.
• What happens if it fails? Towns usually publish a contingency list. It's a fair question to ask what gets cut, and what gets deferred.
• Who else pays? Commercial and industrial property, and any large exempt institutions, shift the split. The residential share is the number that matters to homeowners.

How a Question Gets to the Ballot

An override or exclusion reaches the ballot through your town's own process, typically the select board or town meeting for the question to be placed, depending on your town's form of government. Then it's decided by the voters at a town election. It is a majority vote of those who turn out, which is why turnout on these questions is often the whole story.

Two practical notes. First, these elections are frequently held on a date that isn't the busiest one on the calendar, check the date and put it in your phone. Second, an override that passes is reflected in the tax rate for the fiscal year that begins the following July 1, which means the first bill you see it on may arrive months after the vote.

An override is permanent. A debt exclusion is not. If you only remember one thing, remember that.

Where We Stand

Massachusetts Homeowners United opposes Proposition 2½ repeal and opposes new property-tax burdens that don't come with a vote of the people. We don't tell members how to vote on a specific local question, that's a decision about your own town's schools and services. What we do is make sure you know whether the question on your ballot is permanent before you walk in.
