If Approved, What is the Difference Between an Override and a Debt Exclusion?

Proposition 2½ limits the amount of revenue a city or town may raise from local property taxes each year to fund municipal operations. This amount is known as the annual levy limit. However, the law allows a city or town to increase tax revenues above that limit with approval of voters at an election. G.L. C.59 §21C

An exclusion (known as a Proposition 2 ½ Debt Exclusion) increases the amount of property tax revenue a community may raise for a limited or temporary period of time in order to fund specific projects. The amount of an exclusion may be raised in addition to the community's levy limit. It does not increase the community's levy limit nor become part of the base for calculating future years' levy limits.
