Kingston property tax is billed twice a year: an interim bill due the last business day of February and a final bill due the last business day of June. The amount you owe is your property’s MPAC assessed value multiplied by a combined tax rate that bundles the municipal rate set by city council with the education rate set by the Province of Ontario.1City of Kingston. Paying Your Property Taxes Miss a due date and penalties start the next business day.
How Your Bill Is Calculated
Two numbers determine what you pay: the assessed value of your property and the tax rate for your property class. Multiply them and you have your annual tax. A home assessed at $450,000 at a combined residential rate of 1.3 percent would owe $5,850 for the year.
The assessed value comes from the Municipal Property Assessment Corporation, an independent body that values every property in Ontario. MPAC weighs up to 200 factors, with five doing most of the work: location, lot dimensions, living area, age of the building, and construction quality.2Municipal Property Assessment Corporation. Residential Property Assessments Recent comparable sales in your neighbourhood matter too. You can see the details MPAC holds on your home through its AboutMyProperty portal, and errors there — wrong square footage, a garage that isn’t there — flow straight into your tax bill.
The rate has two parts. The municipal portion funds city services like fire, transit, parks, policing, and road maintenance, and council sets it each year during budget deliberations. The education portion is set by the province; for 2026 the residential education rate is 0.153 percent of assessed value.3Ontario. O. Reg. 400/98 – Tax Matters – Rates for School Purposes Kingston publishes a Tax Rate Schedule each year listing exact rates for residential, multi-residential, commercial, industrial, and other classes.4City of Kingston. Property Tax Bill Information Commercial and industrial properties sit at a higher ratio than residential, which shifts a larger share of the levy their way.
If the numbers on your bill don’t match what you expect, call the city’s tax office. Mistakes in property class or assessed value happen, and they are worth catching early.
When and How to Pay
Kingston issues two bills a year. The interim bill arrives early in the year, is based on 50 percent of the previous year’s annualized levy, and is due the last business day in February. The final bill reflects the current year’s approved rates and is due the last business day in June.1City of Kingston. Paying Your Property Taxes The interim bill is essentially an estimate, so if council raised rates or your assessment went up, the final bill will land noticeably higher than the first one. Budgeting half your expected annual total for each date is a reasonable baseline, with a closer look before June.
You can pay through several channels:
- Online banking: search “Kingston taxes” as the payee and use your 19-digit roll number from the bill as the account number. Allow for your bank’s processing time; the payment has to reach the city by the due date to count as on time.
- Paymentus, the city’s online payment platform, which posts to your account within two business days.
- Cheque or money order dropped off at City Hall (Market Street entrance) or at 1211 John Counter Boulevard by 4:30 p.m. on the due date.
Pre-Authorized Payment Plans
If you’d rather not watch two due dates, Kingston runs two pre-authorized plans that pull funds straight from your bank account.5City of Kingston. Pre-Authorized Tax Payment Plans
The monthly plan spreads your taxes across ten withdrawals from January through October, taken on the first business day of each month. January through June each equal 10 percent of the prior year’s total; July through October are adjusted to reflect the current year’s actual taxes. You won’t get a separate interim bill. You must be fully paid up to enroll, and the sign-up deadline is February 15 for interim billing and June 15 for final billing.
The due date plan automates the regular schedule: the full interim amount is withdrawn on the last business day in February, and the full final amount on the last business day in June.
If you’re already behind, the city offers a separate arrears payment plan with monthly withdrawals. Penalty and interest keep accruing while you’re on it.
What Late Payment Costs
A 1.25 percent penalty hits the unpaid balance on the first day of default — the first business day in March for a missed interim payment, the first business day in July for a missed final payment.6City of Kingston. Property Tax Late Payment Fee After that, 1.25 percent monthly interest is added to any remaining balance on the first day of each following month. That works out to 15 percent a year, more than most consumer debt.
Prolonged non-payment leads somewhere worse. Under Ontario’s tax sale rules, the city can register a tax arrears certificate against the property once taxes have been outstanding long enough. After registration you have either one year or 90 days, depending on property type, to pay the full cancellation price: all outstanding taxes, penalties, interest, and administrative costs.7Ontario. O. Reg. 181/03 – Municipal Tax Sales Rules An extension agreement with the city may be possible before that deadline expires. If no payment or agreement is reached, the city can sell the property at public auction or by public tender; if no buyer comes forward, the property vests in the municipality.
If Your Assessment Looks Too High
The number MPAC assigns is the base for everything on your bill, so a wrong assessment means wrong taxes year after year. The first step is a free Request for Reconsideration through MPAC. For residential properties this step is required before you can go further.8Municipal Property Assessment Corporation. Disagree With Your Assessment File online through AboutMyProperty or by mail. Before you file, pull comparable properties nearby through the portal; that comparison data is your strongest evidence. MPAC aims to complete its review within 180 days, with up to 60 additional days possible.9Municipal Property Assessment Corporation. How to File a Request for Reconsideration
If MPAC’s decision doesn’t resolve it, you have 90 days from that decision to appeal to the Assessment Review Board. The filing fee for residential properties is $132.50 per roll number, with a $10 discount for filing electronically.10Tribunals Ontario. Filing an Appeal The ARB hears evidence from you and MPAC and rules on the value. Comparable sales from your neighbourhood carry the most weight in residential appeals. Business property owners can skip the Request for Reconsideration and file with the ARB directly.
Programs That Can Reduce Your Bill
Several programs can lower what you owe. Each has its own eligibility rules and application process.
Heritage Property Tax Relief
Owners of municipally designated heritage properties can receive a 40 percent reduction, up to $5,000, through Kingston’s Heritage Tax Relief Program.11National Trust for Canada. Tax Relief You need to enter into a heritage easement or equivalent conservation agreement and keep up conservation work to nationally accepted standards. A local Heritage Property Tax Relief Committee reviews applications and inspects periodically to confirm compliance.
Seniors and Persons With a Disability Exemption
Ontario’s Assessment Act exempts the portion of a home’s assessed value tied to renovations or construction that accommodate a senior aged 65 or older or a person with a disability. For an existing home, the increase in assessed value caused by accessibility work is exempt. For a custom-built home, 10 percent of the total assessment is exempt to account for features like wider doorways and hallways.12Municipal Property Assessment Corporation. Exemption for Seniors and Persons With a Disability The home has to be the principal residence of the senior or disabled person and can have no more than three residential units. MPAC sends a confirmation letter every two years; if you miss the response deadline the exemption is removed.
Ontario Energy and Property Tax Credit
Residents who pay property tax on their principal residence can claim the Ontario Energy and Property Tax Credit, delivered through the Ontario Trillium Benefit. You apply by filing Form ON-BEN with your income tax return.13Canada Revenue Agency. Province of Ontario Renters qualify based on rent paid. The credit is income-tested, so lower-income households receive more. Filing a return is the only way to receive it, even if you owe no tax.
Registered Charity Rebate
Registered charities occupying commercial or industrial space can receive a 40 percent rebate on the property taxes for that space. Applications are due by the last business day in February of the year after the tax year in question, and the charity needs a valid CRA registration number.14City of Kingston.
