Quick Answer: How Property Taxes Work in Oakville

Oakville property taxes are calculated using your home’s assessed value from MPAC, multiplied by the applicable municipal and education tax rates.

For budgeting purposes, the simplest and most accurate method is:

Annual property taxes ÷ 12 = your monthly property tax budget

If you only remember one thing, remember this: do not compare homes by price alone. Compare them by total monthly cost mortgage, property taxes, utilities, insurance, maintenance, and commuting.

60-Second Oakville Property Tax Summary (Save This)

Before you buy, you want clear answers to these five questions:

What are the property taxes for this exact address (not the neighbourhood average)?
Is the tax amount based on the current MPAC assessment and current year tax rate?
Will you pay property taxes through your lender or directly to the Town?
Are there upcoming changes, like stormwater fees, that affect monthly budgeting?
What is your true all-in monthly cost after taxes, utilities, insurance, maintenance, and commute?

How Property Taxes Are Calculated in Oakville

Step 1 – MPAC Determines the Assessed Value

MPAC (Municipal Property Assessment Corporation) assigns an assessed value to every property in Ontario for tax purposes. This assessed value is not the same as market value.

Market value is what buyers are willing to pay. Assessed value is used strictly for taxation.

Step 2 – Municipal and Education Tax Rates Are Applied

The Town of Oakville applies its municipal tax rate, plus the education tax rate set by the province, to the assessed value.

The formula looks like this:

Assessed value × combined tax rate = annual property taxes

Step 3 – The Municipality Issues the Tax Bill

Your official tax bill is issued by the Town of Oakville, not MPAC, and includes installment dates and payment instructions.

For budgeting, the most practical method remains:
Annual taxes ÷ 12 = monthly tax budget

Oakville Property Tax Rates Explained

Oakville publishes both interim and final tax rates each year.

As an example, Oakville’s 2025 residential final tax rate was approximately 0.834632 percent.

What this means in practice:

$100,000 of assessed value × 0.834632 percent ≈ $834.63 per year in property taxes

Tax rates can change annually, so always verify the most current rates published by the Town when budgeting.

What’s Changing for Property Taxes in Oakville in 2026

Many buyers ask whether property taxes are increasing in 2026.

According to the Town of Oakville’s published budget communication:
• overall property taxes were projected to rise by approximately 1.96 percent
• this equals roughly $16.33 more per $100,000 of assessed value
• an example home assessed at $800,000 would see an increase of about $130.64, bringing total taxes to approximately $6,807.68

These examples help explain direction, but your actual taxes depend on your property’s assessed value and classification.

Stormwater Fee in Oakville: What Home Buyers Need to Know

Oakville is introducing a stormwater fee to fund stormwater infrastructure, replacing part of what was previously funded through property taxes.

For 2026, the Town has published first-year phased-in amounts of approximately:
• $137 per year for low-density homes (single detached)
• $64 per year for medium-density homes (semi-detached or row homes)
• $30 per year for high-density homes (condos and multi-residential)

This should be treated as a separate budgeting line item and verified close to purchase.

Property Tax Due Dates in Oakville

Oakville issues property tax bills twice per year:
• an interim bill
• a final bill

Each bill includes two installment dates.

Because due dates can change, buyers and homeowners should always confirm the current year’s schedule directly with the Town of Oakville.

How to Estimate Property Taxes Before You Buy

Step 1 – Confirm the Exact Annual Tax Amount

Do not rely on neighbourhood averages. Confirm the tax amount for the specific address you are considering.

Step 2 – Convert to a Monthly Number

Annual property taxes ÷ 12 = monthly tax budget

Step 3 – Add It to Your All-In Monthly Cost

Your real monthly ownership cost usually includes:

• mortgage payment
• property taxes
• utilities
• insurance
• maintenance reserve
• commute costs

Can You Challenge an MPAC Assessment?

If you believe an assessed value is incorrect, MPAC offers a formal Request for Reconsideration process.

In some cases, homeowners may also appeal through the Assessment Review Board.

This is typically more relevant after purchase than during the buying stage.
