St. Thomas property tax

2026 due dates

• last business day of February
• last business day of April
• last business day of July
• last business day of October

Two bills a year. Interim bill (mailed late January or early February; 50% of the previous year's total taxes) due in two instalments on the last business day of February and of April. Final bill (mailed late June or early July; current-year rates less the interim) due on the last business day of July and of October. The City states the rule rather than calendar dates; each bill shows the exact amount and due date of each instalment.

Late payment: 1.25% applied to unpaid taxes on the first business day of the month after the due date, and a further 1.25% on the first business day of each month while unpaid ('This is equivalent to 15% per year').

Look up or pay your bill

No online tax account portal was found on the City's property tax pages; the City says your tax bill shows the balance and due dates and that you can contact the Treasury Department ([email protected], 519-631-1680) for account information. Bill reprints cost $10.
