Supplemental assessments
A supplemental assessment occurs when your property's assessed value or classification has changed due to new construction, renovations, additions, improvements, or a change in the property's use. These assessments are prepared by MPAC and provided to the County after the annual tax bills have already been issued.
As a result, property owners may receive a supplemental tax bill to account for taxes that were not included on their regular tax bill. Supplemental taxes are in addition to any interim or final tax bills previously issued and do not replace those bills.
Important information about supplemental tax bills
- Supplemental tax bills are most commonly issued for newly constructed homes and buildings, or properties that have undergone physical improvements or changes in use.
- Under provincial legislation, supplemental taxes may be charged for the current taxation year as well as up to two previous years.
- If you receive more than one supplemental tax bill, check the effective date shown on each bill, as each may relate to a different taxation year
- Supplemental tax bills are issued once the County receives the updated assessment information from MPAC, typically after final tax billing has occurred, and are generally due in two instalments, approximately 30 and 90 days from the bill date.
- Any regular tax bills you have already received must still be paid in full by their specified due dates, even if you are expecting a supplemental tax bill.
- Arrears and credit balances are not displayed on supplemental tax bills.
If you have questions about why you received a supplemental assessment, or if you disagree with the assessed value of your property, you can contact MPAC directly. Questions related to payment, due dates, or the amount owing on a supplemental tax bill can be directed to our Property Taxes team.
Assessment concerns
If you think that your current value assessment or property classification is incorrect:
If you disagree with MPAC’s decision on your RFR, you have the option to appeal to the Assessment Review Board.
You are still required to pay taxes while awaiting the outcome of an appeal. Once we receive notice of the appeal decision, we will make the applicable changes to your tax roll and adjust your balance accordingly. Any penalties or interest charged on outstanding tax amounts prior to your appeal approval cannot be waived.
Changing your school support
If you are a property owner in Ontario, you must support a school board, even if you do not have children or your children are not currently in school.
The school board you support is noted on your assessment and can be changed through MPAC. By default, your school support is the English Public School Board unless otherwise requested by the owner or tenant.
To learn more about changing your school support, visit the MPAC website.
