Supplementary Bills & Adjustments

Contacts

Annual taxes are calculated by multiplying the assessed value of your property by the Municipality's current tax rate.  

The tax rate is made up of a Township portion and a County portion (influenced by the respective budget requirements) and an Education portion which is set by the Province of Ontario .  

The Municipal Property Assessment Corporation determines the assessed value of each property.

Supplementary bills are issued based on the revised assessment values received from the Municipal Property Assessment Corporation.  

You may receive a retroactive tax bill even two or three years after your new home or improvement has been completed.  

Please be aware that these supplementary tax bills may be substantial and prepare accordingly.  

Current year supplementary billings are issued after the final tax bills are issued.  

Also, any current year reductions due to ARB decisions etc are processed after the final tax bills are issued.
