What Happens to Property Taxes When You Sell a House in Ontario? 2026 Seller Guide
Selling a home in Ontario involves more than agreeing on a price and paying off your mortgage. One closing detail that often surprises sellers is property tax adjustment.
If you've already paid your property taxes for part—or all—of the year, what happens to the money covering the period after you no longer own the home?
Generally, property taxes are adjusted as part of the closing process so the buyer and seller are each responsible for their appropriate portion.
Here's what Ontario home sellers should know.
Who Pays the Property Taxes When You Sell Your Home?
When an Ontario property changes ownership, property taxes are typically divided based on the closing date.
Generally, the seller is responsible for their portion of the property taxes up to the day before closing, while the buyer becomes responsible starting on the closing date. The lawyers account for this through the closing adjustments.
This means you generally don't simply lose money if you've already paid taxes covering a period after your closing date.
What Is a Property Tax Adjustment?
A property tax adjustment is essentially a calculation used to make sure the buyer and seller each bear the appropriate property taxes for their period of ownership.
The adjustment is generally reflected on the Statement of Adjustments prepared during the closing process.
Think of it as balancing the account between the buyer and seller.
If you've paid more than your share, an adjustment can credit you accordingly.
If you haven't paid your full share, the closing figures can be adjusted in the other direction.
What If You Already Paid Your Property Taxes for the Entire Year?
This is a common question.
Suppose you sell your home during the year but you've already paid property taxes covering a later period.
You wouldn't normally be expected to simply absorb the taxes attributable to the buyer's ownership period.
Instead, the appropriate amount can be credited back to you through the closing adjustment. LAWPRO's Ontario home-buying and selling guide specifically explains that if the seller has already paid the year's taxes, the seller is entitled to a credit for the overpayment.
A Simple Property Tax Example
Suppose your annual property taxes are $7,200.
That's approximately $600 per month for a simple illustration.
Now imagine you sell and close around the middle of the year, but you've already paid the municipality for taxes covering the entire year.
Part of that payment relates to the months when the buyer will own the property.
Instead of asking the municipality to divide the transaction between you and the buyer, the lawyers generally account for the appropriate amount through the closing adjustments.
The actual calculation is based on the transaction details and applicable dates, so your lawyer will determine the final figure.
What If You Still Owe Property Taxes When You Sell?
The adjustment can also work in the opposite direction.
If property taxes attributable to your ownership period haven't yet been paid, that can be accounted for in the closing calculations.
The goal is to appropriately allocate the property's expenses between the parties.
If you're unsure whether your municipal property tax account is current, it's worth checking before closing rather than discovering an unexpected amount at the last minute.
Where Will You See the Property Tax Adjustment?
Property tax adjustments generally appear on the Statement of Adjustments.
This document helps calculate the final amount required between the buyer and seller at closing and can include adjustments for certain property-related expenses.
Your real estate lawyer can explain exactly how the property tax adjustment affects your particular transaction.
Are Property Taxes Part of REALTOR® Commission?
No.
Property taxes and real estate commission are separate expenses.
Property taxes are municipal charges associated with owning the property.
Real estate commission is compensation paid according to the applicable listing and cooperating brokerage arrangements.
Legal fees, mortgage discharge costs and other closing expenses are also separate.
This is why sellers should look at their estimated net proceeds, rather than simply subtracting their mortgage from the expected selling price.
What About Supplementary Property Taxes?
Some properties can also receive supplementary tax bills.
For example, changes involving new construction, additions, improvements or changes in property use can result in assessment changes and supplementary taxation after MPAC provides updated assessment information to the municipality.
If your property has recently been built or significantly changed, discuss any potential outstanding or supplementary tax issues with your lawyer and municipality.
Does Selling Your House Automatically Change Its Property Taxes?
A sale itself doesn't simply mean the new owner's property tax bill becomes the same percentage of the purchase price.
In Ontario, MPAC determines property assessments using its assessment system, while municipalities use assessment values and applicable tax rates in determining property taxes.
That's separate from the property tax adjustment that takes place between a buyer and seller on closing.
Know Your Numbers Before You Sell
Property taxes are only one part of calculating what you'll actually receive when your home sells.
Before listing, it's helpful to estimate:
- Your expected selling price
- Remaining mortgage balance
- Potential mortgage penalty
- Real estate commission
- Legal and closing costs
- Property tax adjustments
- Your estimated net proceeds
Understanding these numbers before accepting an offer can help prevent surprises later.
