Updated Checked by the Tax-Services.ca editorial team How we check
You can usually pay a property tax bill at your bank, through online or telephone banking, by cheque in the mail, or through your mortgage company, and the payment must reach the municipality on or before the due date. We checked the City of Windsor, Ontario as a worked example. Your own municipality’s page is the one that decides, so use this as a checklist of questions.
How can you pay a property tax bill?
Windsor lists five routes, and most cities look alike.
| Way to pay | What to watch |
|---|---|
| Bank, credit union or trust company | Pay on or before the instalment date on the bill |
| Telephone or online banking | Add the municipality as a payee and use the account number on your bill |
| Cheque by mail | Post early, because the city needs it by the due date |
| Through your mortgage company | Confirm your lender really pays it, and from which account |
| City drop box | Sealed envelope, cheque or bank draft only in Windsor’s case |
Online banking is the one we’d pick. There’s a record, it doesn’t depend on the mail, and you can set it a few days early. Just remember that the date that counts is the day the city receives the money, which may be later than the day you click.
Say Alex pays at the last minute on a Friday evening before a long weekend. Online banking may not move the money until the next business day, and that day can fall after the due date. Paying by Wednesday would have cost nothing and saved a penalty.
Should you pay in instalments or sign up for automatic payments?
Windsor offers three pre-authorized plans for the final bill: one that follows the three regular instalment dates, and two that split the balance into five payments. That can make a big bill easier to carry. A $2,700 final bill is $900 three times, or $540 five times.
Ask three things before you enrol. Which date does the plan use? What happens if a payment bounces? Can you leave the plan without a penalty? Cities put these answers on their own pages, and we couldn’t confirm them for every place.
If you’re a first-time owner, the closing costs calculator covers the cash at purchase, and the mortgage payment calculator shows what the loan adds each month. Property tax is the third line in that monthly picture, so add it before you commit.
What if your mortgage company pays the tax?
Some lenders collect a share of the tax with each mortgage payment and send it on. If that’s you, the bill may still arrive at your door. Don’t assume it’s settled. Look at the account number and the amount, then check with the lender that the payment went in.
When the tax goes up, the lender can raise your monthly amount to match. A surprise in the mortgage statement often traces back to the tax bill, not the interest rate.
What does it cost if you pay late?
Every municipality in Ontario sets its own rules inside provincial law, so read yours. Windsor says that once an account is past due, penalties and interest of 1.25% a month apply, which it says can equal 15% a year if left alone. A missed $900 instalment costs $11.25 for one month and $33.75 for three.
That’s not ruinous for a short delay. The trouble comes when the balance sits. Windsor describes arrears notices with rising fees, then a tax registration lien on an account more than three years past due. After a lien, the city may offer the property for sale once a year has passed.
Behind on payments? Call early. Windsor runs a Tax Repayment Program with terms up to five years, and staff can be reached through 311. Other cities have similar options, but we can’t say which ones.
How do you work out what you owe?
Your bill is the assessed value times the total rate, less anything already paid. The Ontario government describes the same idea on its property tax page: the assessment is set by MPAC and the rates are applied to it by class. A $300,000 assessment at a 1.7% example rate is $5,100 a year. Try your own numbers in the property tax calculator, which also splits the year into months and handles a credit.
Did you buy or sell partway through the year? Ask your lawyer how the tax is split on closing day, so you don’t pay the same stretch twice.
What if the bill doesn’t arrive?
Call the municipality’s tax office rather than waiting. The assessment notice you get from MPAC is not the tax bill, and a recent move or a changed mailing address is the usual reason a bill goes astray. Keep a note of the date and the name of whoever you spoke to. A five-minute phone call is cheaper than a month of penalties.
Where we got these figures
Payment methods, the pre-authorized plans, the 1.25% monthly penalty, the lien rule and the repayment program come from the City of Windsor’s tax pages, read in September 2026. The Government of Ontario says each municipality prepares its own tax bill. The examples are our arithmetic, with a rate we chose for illustration.
