Statements of account

You can obtain a school tax statement of account in any of the following ways:

  • To view an up-to-date statement of account online, go to School tax on-line. To register, you will need your most recent school tax bill.
  • Go in person to the Comité de gestion’s payment counter. For security purposes, you will need to show a piece of ID.
  • Call the Comité de gestion and ask to have a copy of your statement sent to your account mailing address.
  • Request a copy of your statement of account by mail, fax, or email. It will be sent to your account mailing address.

There is a $10 service charge for copies of statements of account or school tax bills issued in prior years. There is no charge for current-year statements of account or school tax bills.

The Comité de gestion is a public body governed by the Access to Information Act. This legislation protects the information held and limits disclosure of personal information related to individuals and their accounts. Only owners, co-owners, and those they authorize (with proof) may obtain statements of account.

The Comité de gestion only issues receipts for payments made at its payment counter. Cancelled cheques, the portion stamped by your financial institution, or your transaction records are your proof of payment. The retained portion of the tax bill may be used for income tax purposes.

The Access to Information Act limits disclosure of personal information related to individuals. For anyone other than property owners to gain access to statements of account, a proxy form must be signed. It can be found here: Proxy Form – School Tax.

Change of ownership

The Comité de gestion receives a copy of all assessment certificates confirming property transactions, along with the name and contact information of the new owners, from municipalities. These certificates are issued once the transactions have been published in the land register.

It can take weeks, or even months, following the date of the transaction for the certificate to be received by the Comité de gestion. The new owner is responsible for ensuring that the Comité de gestion has their contact information.

The new property owner must ensure that the notary includes school tax payments in the adjustments made when ownership is transferred. The Comité de gestion is not responsible for making those adjustments.

The Comité de gestion does not issue a new school tax bill when ownership is transferred. The new owner may, however, access their school tax account online.

Refunds due to negative certificates or decisions made by the Tribunal administratif du Québec are issued once the certificates have been received from the municipal evaluators.

Refunds due to overpayments are issued at the owner’s request or following a review of the credit balance. The service charge for issuing a refund for overpayment is $20. Unless an immediate refund is requested by the owner, credit balances of less than $320 are carried forward to the next year.

Refund cheques for overpayment are made payable to the owner whose name is on the account at the time the refund is processed. If ownership has changed hands in the meantime, the new owner must send a written notice indicating to whom the refund should be paid.

Reminder notices and debt reovery

Interest is charged on all late or insufficient instalment payments.

A $25 service charge is added for every returned cheque (NSF, stop payment, frozen account, etc.).

The Comité de gestion periodically mails out reminder notices indicating balances due. Interest is calculated as of the due date of each reminder.

In case of non-payment, the Comité de gestion may recover its debts in three ways:

  • Seizure and sale of personal property
  • Sale of immovables for non-payment of school taxes
  • Personal action under common law

Sale of immovables for non-payment of school taxes

A sale of immovables for non-payment of school taxes is held each December. The list of immovables to be sold is approved by the Comité de gestion by November 1 and is published three times in a Greater Montreal newspaper.

The sale of a property for taxes may be avoided through payment of the taxes due, the accumulated interest, and the expenses incurred prior to the date of the sale.
