If you’re a homeowner in Montreal, you may receive a notice showing your property’s municipal assessment. This value will determine your property taxes for the upcoming three‑year roll. If you believe it’s too high, you can contest it to potentially reduce your tax bill.

What Is a Municipal Assessment?

Every three years, Montréal prepares a property assessment roll based on the estimated market value as of July 1 of the previous year. For the 2026–2028 roll, the benchmark date is July 1, 2024.

This roll lists all properties across the Montréal agglomeration and provides the assessed value used by the city to calculate municipal and school taxes.

If the city's estimate is significantly above your actual market value at that date, you might be overpaying—potentially for three years.

When Is the Deadline for Contesting?

Assessment notices will be mailed in fall 2025, and your deadline to apply for a review is the later of:

• 60 days after receiving your notice, or
  
  

• May 1, 2026
  
  

If your property is valued at $3,000,000 or more, the deadline extends to 120 days unless the notice is posted online within 60 days.

Missing these deadlines means the assessment—and tax rate—is set until 2029.

️ How to Contest a Municipal Assessment

1. Review Your Notice

Check your Avis d’évaluation foncière carefully. You can also consult your assessment via EvalWeb (requires address + lot or roll number).

2. Compare Market Value

We’ll provide a free CMA based on July 2024 comparables to assess whether the assessment is reasonable.

3. Submit a Request for Review (“Demande de révision”)

You can file online via the City’s form, in person at the Main Point of Service (255 Blvd Crémazie Est, Suite 700), or by mail. A small fee applies based on property value. Payment completes the filing, so retain proof .

Your written reason should explain the market-based argument—tax burden alone is not valid grounds for review.

4. Wait for the City’s Decision

The assessor must respond by September 1, 2026, or—if extended—by April 1, 2027.

If no response is received by the deadline, you still have recourse to proceed.

5. Appeal to the Tribunal administratif du Québec (TAQ)

If you’re unhappy with the assessment agency’s ruling, you may file an appeal with the TAQ’s Immovable Property Division within 60 days of receiving their decision—or within 30 days if no response was timely made.
