How does a debt exclusion differ from an override? Both are Proposition 2½ questions and, in municipal finance language, both are technically overrides. However, there are some basic differences. While both will increase your property taxes, a debt exclusion is a temporary increase while an operating override is a permanent increase in the town’s tax levy limit. A debt exclusion finances a particular project(s) and your taxes increase for a period of time, usually 10-20 years, to cover the cost of the project. When the financing bond is paid off, your tax increase for that project goes away.

Why are there two votes – one at the polls and one at Town Meeting? A debt exclusion is required to pass two thresholds: a simple majority at the ballot and a two-thirds majority at Town Meeting.
