School Taxation


The Comité de gestion de la taxe scolaire de l'île de Montréal imposes and collects the school tax on behalf of the school service centers and school boards of the Island of Montreal:

The school taxe rate was set by the Minister of Education and Higher Education and published on June 13, 2020, Official Gazette.  For 2020-2021, this rate is $0,10540 for each $100 of evaluation.

The territory of the Comité de gestion is composed of the city of Montreal, of the 15 municipalities on the Island of Montreal and the 23 municipalities located west of the island of Montreal in the Harwood territory. Within the territory of the Island of Montreal, property owners are taxed by the Comité de gestion; in the Harwood territory, only property-owners considered to be English-speaking or “neutral” receive a school tax bill from the Comité de gestion. The French-speaking school service centers in this territory, Centre de services scolaire des Trois-Lacs, imposes its own school tax on French-speaking property owners.


On January 3rd each year, the Comité de gestion allocates to each of school service centers their share of the school tax. The total amount billed is distributed among the school boards, whether it has been collected or not.

Additional revenues from the imposing and collecting of the school tax and the supplementary bills serve to upgrade education in underprivileged areas of those school on the Island of Montreal.


The school tax pay for about 15% of the expenses of school boards on the Island of Montreal.

The school tax is used for the following:

  • maintenance of buildings and equipment;
  • energy consumption;
  • management costs for schools and centres;
  • part of the cost of school transportation.
