A transfer of immovables is a transfer of the right of ownership on a property as a result of a contract of sale, rental of more than 40 years, transfer of the rights of the emphyteutic lease or donation. Duties on transfers of immovables – also known as the ‘Welcome Tax’ – are charges that are payable when the right of ownership on a property is transferred. The buyer is responsible for paying these duties. Where there is more than one buyer, they are joint and severally liable for payment of the transfer duties. Every municipality must collect duties on the transfer of any immovable situated within its territory. (Act respecting duties on transfers of immovables – R.S.Q., chapter D-15.1). The tax is calculated as follows:

$0 – $51,700 0.5% (0.0050)
$51,700 – $258,600 1% (0.0100)
$258,600– $517,100 1.5% (0.0150)
$517,100 and more 2% (0.0200)

The duties on transfers of immovables are imposed at the time of purchase of an immovable and are payable in one installment.

Comparison Factor

The comparison factor for 2020 is 1.00. Where the imposition is made on the basis of the market value at the time of the transfer, the value on the roll must be multiplied by the comparative factor of the fiscal year that corresponds to the registration date.
