Supplementary Assessment
When the increase in value of the new building has been determined a supplementary assessment and tax notice will be sent to the property owner indicating the additional taxes for the year.
Supplementary Assessments are levied only in the year the newly constructed building is completed. There are two supplementary notice mailings for the Town of Okotoks. Property owners are required to pay the supplementary tax in full within 30 days of mailing.
The Town of Okotoks calculates Supplementary Assessments as per the example below:
Type of Property
Residential Single Family Home
Total Assessment (Annual & supplementary assessment)
$350,000
Less annual assessment shown on the Assessment Notice
$150,000
Supplementary Assessment
$200,000
Improvement completed on pro-rated Supplementary Assessment
July 1st (= 6 months)
$200,000 x 6/12 months =
$100,000
*The tax rate is then applied to the pro-rated Supplementary Assessment to calculate the taxes due on the Supplementary Assessment.
The Town of Okotoks Supplementary Assessments is based on typical market values with a valuation date as of July 1st of the previous year.
