The amount of property tax owing on your land and/or building is the result of a calculation based on four factors:

  • the market value assessment of your property
  • the tax class into which your property falls
  • the tax rate for that class (set annually by your City Council)
  • the tax rate for the Education (school support) portion of that class (set annually by the Province of Ontario)

Property tax, in the City of St. Thomas is generally billed twice a year. There are four due dates, in February, April, July and October, with a grace period until the last business day of each month.  Final due dates for 2018 Taxes are July 25th and October 25th.

The amount owing in February and April is charged on the Interim Billing. The Interim billing is an amount equal to 50% of the previous year's property tax.

The amount owing in July and October is charged on the Final Billing. This Final Billing reflects the new tax rate determined by City Council in support of its annual budget, less the amount billed on the Interim. "Please retain this final bill for income tax purposes. Reprints may be obtained by the property owner and will be subject to a $5.00 fee."

A Supplementary (or Additional) tax bill may be issued as we receive information that changes the assessed value or the tax class of a property. The most common example of this is the completed building of a new home. The taxes billed prior to the building of the home are generally for the land only. When the home is complete, and we are advised of the assessed value, a ‘supplementary' tax bill will be created to reflect the amount of taxes due for the ‘house' portion of the property. A supplementary tax bill is usually due in one installment, 21 days after the generation of the bill. Future tax bills will be issued as above.
