How to Find the Taxable Value of Your Home & Why It Matters
When preparing to sell your home, you’re likely focused on curb appeal, home staging, and finding the right real estate agent. But here’s a question most sellers forget to ask upfront: How to find taxable value of home? This figure is more than just a line on a property tax bill — it can significantly impact your sale strategy, pricing, and the financial outcome of your transaction. Understanding your home’s taxable value isn’t just for accountants or tax preparers; it’s an essential piece of the puzzle for sellers, especially in competitive markets like Mississauga.
What Is the Taxable Value of a Home?

The taxable value of your home is the dollar amount used by local governments to calculate property taxes. It’s typically derived from the assessed value, which is determined by a municipal assessor or provincial agency based on a combination of market value, property features, and local tax laws.
In Ontario — and specifically in cities like Mississauga — this value is determined by the Municipal Property Assessment Corporation (MPAC). MPAC reassesses property values every four years, though property tax bills are sent annually. The last reassessment was scheduled for 2020 but postponed due to COVID-19, meaning many homes are still taxed based on 2016 valuations.
According to MPAC, the average residential property in Mississauga saw a 38% increase in assessed value between 2012 and 2016. That’s a significant jump — and it shows why taxable value matters when it’s time to sell.
Why Does Taxable Value Matter to Sellers?
1. It Influences Buyer Perception
Savvy buyers often research the property’s tax history and assessed value before making an offer. A home with unusually high taxes may turn off some buyers, especially first-timers concerned about monthly payments. On the flip side, a lower taxable value could be a selling point.
2. It Affects Capital Gains Tax Reporting
If you’re selling an investment property or a second home, the taxable value can help you calculate adjusted cost base (ACB) and eventual capital gains taxes. It’s critical to get this right — the Canada Revenue Agency (CRA) doesn’t take mistakes lightly.
3. It May Signal Under or Over-Valuation
If your home’s taxable value is much lower than market value, it could be a signal that your property hasn’t been reassessed in years, or that you’re missing out on potential tax breaks. On the other hand, a higher taxable value might indicate the city sees your home as worth more than it actually is — a red flag for over-assessment.
How to Find the Taxable Value of Your Home
This part is surprisingly simple, but you’d be shocked how many homeowners never look it up.
Step 1: Check Your Property Tax Bill
Your annual property tax bill shows the assessed value used to calculate your taxes. This is your taxable value unless there are special adjustments (like for newly built homes or improvements).
Step 2: Visit AboutMyProperty.ca
MPAC operates this portal, where Ontario homeowners can view detailed information about their property’s assessed value. Create a login using your Roll Number (found on your tax bill) and access historical data and comparisons with other homes in your neighborhood.
Step 3: Compare Market Value vs. Taxable Value
Many sellers confuse market value — what buyers are willing to pay — with taxable value. The two aren’t the same. For example, in Mississauga, real estate prices surged post-2016, but property assessments haven’t caught up due to the reassessment freeze.
A real estate agent can help you analyze how your taxable value compares with recent sale prices. This is especially helpful if you’re wondering whether to appeal a property assessment or highlight low taxes as a selling feature.
What Most Websites Won’t Tell You About Taxable Value
1. You Can Appeal Your Assessment — But Timing Matters
If you believe your taxable value is too high, you have the right to file a Request for Reconsideration with MPAC. Most homeowners don’t know that even while preparing to sell, this can be a useful tool.
Example: Say your neighbor’s home, which is nearly identical, has a taxable value 15% lower than yours. A successful appeal could reduce your tax burden — and make your listing more attractive.
2. Renovations Can Trigger a Reassessment
If you recently renovated — especially kitchens, bathrooms, or added square footage — MPAC might increase your taxable value. Many sellers are surprised to learn that building permits are shared with MPAC, and assessments can follow months after renovations are complete.
According to the Toronto Star, over 35,000 Ontario homeowners saw their assessments increase after major renovations in 2021.
3. Vacant Properties or Investment Units Are Treated Differently
If your Mississauga home was rented out or left vacant, it may fall under different tax classifications, meaning your taxable value might not align with neighboring owner-occupied homes. Always verify how your property is categorized.
The Mississauga Real Estate Market & Taxable Value Trends
Mississauga has long been one of the GTA’s most dynamic real estate markets. With high demand, a diverse population, and proximity to Toronto, it’s no surprise that property values — both assessed and market — have trended upward.
However, the delay in MPAC reassessments means that homes listed today may be significantly undervalued on paper. For sellers, this is a double-edged sword. Lower taxes may attract budget-conscious buyers, but they could also create confusion when buyers compare assessed values with listing prices.
