Review the property transfer duty brackets and rates available in Le Sud-Ouest for 2026, then estimate the welcome tax that may apply to a real estate transaction.
The property transfer duty estimate uses the highest amount required by the applicable rules to establish the tax base, so the sale price is not always the only amount considered. The result is indicative.

01 · Search by address
Search for an address in Le Sud-Ouest to find the property and its municipal assessment, then put the rates available for Montréal into context. The estimate remains indicative and does not replace the official tax bill.
02 · Connected data
Immocalcul brings the available municipal property tax, school tax and property transfer duty data together around one property, so you do not have to search in several places. When information is unavailable, it is simply not displayed.
03 · Transparent estimate
The calculator uses only the available tax components to produce an indicative estimate. Additional charges may appear on the municipality’s official tax bill.
In Le Sud-Ouest, each displayed rate applies only to the portion of the tax base that falls within its bracket.
The tax base is split across progressive brackets. Only the portion within each bracket is multiplied by that bracket’s rate. The calculator applies only the available brackets and comparative factor.
For each property type, we take the middle assessed value among the properties analyzed (the median), multiply it by the comparative factor of 1, then apply the 2026 brackets. The price paid or the amount in the deed may increase the official amount. The median values cover all of Montréal, not only Le Sud-Ouest.
