Supplementary and omitted 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 usually issued twice per year (early fall and late fall) and are in addition to any other tax bills that may have been issued. Each bill includes the effective date and change reason. They are due in two instalments and notice is provided at least 21 days before the payment is due. 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.
