What is a supplementary assessment?
A supplementary assessment applies to a newly constructed property that is completed or occupied during the current tax year. This ensures that newly built homes and buildings contribute fairly to municipal services.
How is the supplementary tax calculated?
The supplementary tax is based on the increase in property value between the property’s annual assessment (value as of the prior year-end) and the value upon completion or occupancy.
Taxes are then prorated based on the number of months the property was completed or occupied.
Supplementary assessments and tax bills are mailed no later than Oct. 31. Payments are due Dec. 31.

Property assessments
If you’ve reviewed and compared your assessment and still have questions or concerns, reach out to an assessor. If you’re not satisfied after speaking with an assessor, you may file a formal complaint with the Assessment Review Board. Formal assessment complaints must be submitted within the 60-day review period.
Changes to assessments will be considered only if the inquiry is received during this legislated time frame.
