Supplementary assessment and tax provides for equity among property owners. When new homes and buildings are completed or occupied, the owners receive municipal services. Supplementary tax contributes towards the cost of providing these services.
If a new building or addition to an existing building is completed in the calendar year, a supplementary assessment is prepared. Supplementary assessment reflects the increase in value of a property where a new home or building is completed or occupied during the current tax year.
A supplementary tax bill will reflect the number of months that the building was completed or occupied during the year. Supplementary tax is determined by pro-rating the supplementary assessment (increase in value) amount based on the number of months the building has been completed or occupied multiplied by the applicable tax rate. Supplementary notices are sent out between June and December.
