Tax Billings

Supplementary Tax Billings - New Construction and Property Changes

Supplementary (assessments when “change events” result in your property being assessed in a different property class) and omitted (any land that should have been assessed has been omitted from the tax roll for the current and/or the two preceding taxation years) tax bills are sent out as a result of a change in your property during the taxation year. These changes can include, but are not limited to: new residential homes, new commercial, residential or multi-residential units, changes in tax classes, additions or renovations to buildings and previously exempt properties that become taxable.

These bills follow the Property Assessment Change Notice issued by MPAC. MPAC is responsible for assessing the properties and forwarding the information to the Township for billing. Sometimes these bills can span more than one year depending on when an MPAC assessor is able to visit your property.

Supplementary and Omitted tax bills are in addition to any other tax bills that may have been issued. They are due in one instalment and notice is provided at least 21 days before the payment is due. 

How to read your Property Assessment Notice

Please contact MPAC (phone: 1-866-296-6722) for questions regarding the assessment amount used to calculate a supplementary bill or the number of days indicated on the bill.
