How to Reduce Your Property Taxes in Markham, Ontario

Property taxes in Markham are an unavoidable part of homeownership but the good news is that there are legitimate ways to lower (or appeal) your property tax bill. Whether you're a long-time resident or a new homeowner in Markham, understanding these strategies can help you save hundreds (or even thousands) per year.

Here’s your expert guide to reducing your property taxes in Markham, Ontario.

1. Review Your MPAC Assessment Carefully

Your property taxes are based on the assessed value assigned by MPAC (Municipal Property Assessment Corporation) not the current market value.

You can reduce your taxes if your home is over-assessed.

What to check for:

Incorrect square footage
Wrong number of bedrooms/bathrooms
Basement finished vs. unfinished
Incorrect lot size
Wrong building type or age
Duplicate improvements or renovations that don’t exist

If MPAC has incorrect information, you may pay more taxes than you should.

2. File a Request for Reconsideration (RfR)

If you believe your home is over-assessed, you can file an RfR with MPAC this is free and often leads to successful tax reductions.

You must provide evidence such as:

Comparable homes with lower assessments
Errors in MPAC’s data
Market analysis from a trusted local realtor (Michael can provide this)

Pro tip: Many Markham homeowners successfully reduce taxes after an RfR when supported by professional comparative market data.

3. Compare Your Assessment With Similar Homes in Your Markham Neighborhood

Your home should be assessed similarly to comparable properties in your area.

Check homes that match your:

Square footage
Lot size
Age
Neighborhood (e.g., Unionville, Cornell, Greensborough, Wismer)

If comparable homes are assessed lower, you may have a strong case for reduction.

Michael can prepare a custom neighborhood comparison report for supporting your appeal.

4. Apply for Eligible Property Tax Rebates or Relief Programs

Markham and York Region offer several programs that can reduce taxes for eligible homeowners.

Programs include:

Senior Homeowners’ Property Tax Grant
Disability Tax Relief
Charity & Non-Profit Rebates
Vacancy Rebate (commercial only)

Even if you think you may not qualify, it’s worth reviewing many homeowners overlook these programs.

5. Avoid Unnecessary Home Improvements Before Reassessment

Major renovations (like additions or finishing a basement) can increase your assessment and your taxes.

If you’re planning to sell soon, Michael can help you prioritize which improvements increase resale value without raising your tax burden unnecessarily.

6. Consider a Professional Property Tax Consultation

If your assessment seems drastically higher than similar homes, consider hiring a property tax consultant or having Michael prepare a professional comparative report.

7. Stay Updated With Markham’s Annual Tax Policies

Markham City Council adjusts tax rates annually. Understanding these changes can help you predict and manage your tax bill more effectively.

Michael regularly tracks Markham market statistics and tax updates for clients.

When Should You Appeal Your Property Taxes?

You should consider an appeal if:

Your home is assessed higher than similar homes nearby
MPAC’s data contains errors
The assessment increased significantly without reason
You recently purchased your home at a lower price than MPAC’s valuation

Final Thoughts

Reducing your property taxes in Markham is absolutely possible but you need accurate data and strong evidence to build your case.

Whether you're reviewing your assessment, preparing to appeal, or considering a move, having a trusted Markham expert by your side makes all the difference.
