Property Tax

Assessments & Appeals

We help you understand the valuation parameters, legislation and tax policy that drive each property’s assessment and tax liability.

We assist clients in reducing their property tax burden by appealing inequitable or erroneous property assessments. 

Unlike other taxes, property tax assessments are based on the estimated value of the property, and thus, are subject to varying opinions. Property taxes represent a significant portion of your operating costs. Minimizing this tax liability improves the competitiveness and liquidity of your assets.

Our consultants specializing in the field of Municipal Taxation boast a combined experience of  25 years and are adept at filing tax contestations, negotiating settlements, and working in close cooperation with experts (lawyers-municipal law) to debate all relevant issues before the real estate administrative tribunals.

We strongly recommend that property owners gather all relevant information, such as Notices of Assessment, tax bills and economic data (i.e. rent rolls, statements of income and expenses, and the like) and seek counsel as to whether the subject property should be the object of a tax contestation.

We also assist our clients in the following areas:


Realty tax budgeting and due diligence


Budgeting future taxes on existing properties


Estimated taxes on new developments


Complete due diligence reviews on potential acquisitions


Tax management: real estate tax recoveries consistent with lease tax clauses permitting an accurate allocation of taxes.


A contestation or assessment appeal is a two (2) stage process. It begins with the filing of an Application for Administrative Review (the “Application”) which is submitted to the assessing authority (for example: Service d’évaluation de la Ville de Montréal), using the prescribed form to urge the grounds which would justify a reassessment of the subject property, the whole accompanied by the appropriate filing fee and postmarked no later than April 30th of the first year of the triennial roll.

Such initial review process allows both the taxpayer and municipal assessor to express their respective opinions in a strictly administrative context, without, however limiting the taxpayer’s recourse.

The municipal assessor has the obligation to respond to the Application by no later than the fall of the first year of the triennial roll.

In the event the municipal assessor disputes the assertions of the taxpayer, the next step requires the filing of a Motion Introductive of Recourse with the Administrative Tribunal of Québec, Real Estate Affairs Division (Tribunal Administratif du Québec, section des affaires immobilières). Such motion must follow the prescribed form (albeit different from that of the administrative process) and must also be accompanied by a filing fee corresponding to the subject property’s assessment.
