Understanding Proposition 2½

Proposition 2½, approved by Massachusetts voters in 1980 and first implemented in fiscal year 1982, limits the amount of property tax revenue Massachusetts cities and towns may raise each year.

How Proposition 2½ Works

Massachusetts General Laws Chapter 59, Section 21C limits the amount of property taxes a community may levy while providing options for voter-approved changes to taxing authority.

Levy Ceiling
A community cannot levy more than 2.5% of the total full cash value of all taxable property in the community.
Levy Limit
The allowable levy generally cannot increase by more than 2.5% of the prior year's maximum allowable limit, plus allowable increases such as new growth.

Voter-Approved Changes

Proposition 2½ allows voters to approve changes to a community's taxing authority through overrides, exclusions and underrides.

Override
PERMANENT INCREASE
Increases the amount of property tax revenue a community may raise in the specified year and in future years. The increase is included in the levy limit and may fund recurring municipal expenses, such as annual operating and fixed costs.
Exclusion
TEMPORARY INCREASE
Allows additional property tax revenue to be raised for a limited period for specific capital purposes. The additional amount does not count toward the levy limit used to calculate future years. Examples include public buildings, public works projects, land and equipment acquisitions.
Underride
PERMANENT DECREASE
Allows voters to reduce the community's taxing authority. An underride decreases the amount of property tax revenue the community may raise in the specified year and in future years.

Frequently Asked Questions

Select a question below to view the answer.

1. What is the levy limit?

The levy limit is the maximum amount a community can raise through property taxes in any given year. It is based on the previous year's limit plus allowable increases, including the annual 2½ percent increase, new growth, and overrides.

The levy limit will always be below or at most equal to the levy ceiling of 2½ percent of the total full and fair cash value of the community's taxable real and personal property. A community may also levy above the levy limit or ceiling by way of an exclusion.

2. What is the difference between an override and a debt exclusion or capital outlay exclusion?

An override is a voted increase in the levy limit and cannot raise it above the community's levy ceiling. When approved, an override permanently increases the community's levy limit and requires majority approval by the electorate.

Exclusions allow a community to assess taxes above its levy limit or levy ceiling for certain capital projects or specified debt service costs. A debt exclusion applies to debt service, while a capital outlay expenditure exclusion applies to capital project costs. Unlike overrides, exclusions do not become part of the base used to calculate future levy limits.

3. What is an underride?

An underride reduces a community's levy limit. The underride amount is subtracted from the levy limit, permanently reducing the base used to calculate future levy limits. Underrides require majority approval by the electorate.

4. What determines a community's tax rate?

A tax rate is set after the community's levy limit, the amount needed to be raised through taxation and property assessments reflecting full and fair market value, is finalized.

Tax Rate = Total Levy ÷ Total Property Value × 1,000
5. When and why do tax rates increase?

Tax rates can increase due to higher amounts needed to be raised through taxes, declining property assessments, overrides or exclusions, new growth, use of previously unused levy capacity, or changes to the prior year's tax base through the abatement process.

6. Why is setting a timely tax rate important?

Until a tax rate is finalized, the community cannot send an actual property tax bill. Setting the rate promptly allows bills to be issued on schedule and helps maintain municipal cash flow. Delays may require borrowing or create additional billing expenses.

7. Why and when do we hold a classification hearing?

A classification hearing is held annually to determine whether to shift some of the property tax burden from one property class to another. The Town Council holds the public hearing after assessments are finalized and before the tax rate is set.

Options may include reallocating portions of the tax obligation among property classes. Adopting one or more of these options may result in multiple tax rates.

8. Do the values have to be final before holding a classification hearing?

Yes. The Assessors must finalize all assessments for the fiscal year before the Town Council votes on allocating the tax burden. This allows the allowable shifts and their impacts to be accurately calculated.

9. What does it mean to have a split tax rate?

Taxable property is categorized as Residential, Open Space, Commercial, Industrial, or Personal Property. A split tax rate generally means using different rates to shift a portion of the tax burden from Residential and Open Space property to Commercial, Industrial, and Personal Property.

10. How does a municipality determine the amounts to be budgeted for the overlay and estimated receipts on the Tax Recap?

The Assessors determine the amount budgeted for the overlay, which covers abatements and exemptions. Estimated receipts are determined by the officials responsible for budget estimates, with input from the municipal financial team.

The overlay worksheet includes a three-year history of the account, while estimated receipt projections generally consider prior actual revenues and anticipated changes for the coming year.

11. What are "other amounts to be raised"?

These are amounts included on the tax rate recap to fund certain expenditures or cover deficits. Examples include debt service, court judgments, snow and ice deficits, state and county charges, Cherry Sheet offsets, overlay allowances and revenue deficits.

12. If we do not levy to the limit, do we lose that levy capacity?

No. A community that chooses not to levy to its full capacity in one year does not lose that capacity in future years. The community may later levy up to its new full limit, which can result in an overall levy increase greater than 2½ percent.

13. How is the average single-family residential tax bill calculated?

The total assessed value of all single-family parcels is divided by the number of single-family parcels to determine the average value. That value is multiplied by the residential tax rate and divided by 1,000 to determine the average single-family tax bill.

14. Why did my tax bill go up more than 2½ percent?

Proposition 2½ regulates the community's levy limit; it does not limit an individual property owner's tax bill to a 2½ percent annual increase.

Individual bills may increase by more than 2½ percent due to unused levy capacity, new growth, overrides or exclusions, property revaluation, new construction, or changes in the real estate market.
