To start, grab your T4 slip and find the amount of income tax deducted. Note this amount on line 437 of your federal return. Then, multiply this number by 45 percent and write the result on line 438. Finally, transfer that amount to line 454 of the return you submit to Revenu Québec. For more information please refer to this link from TurboTax Hub and CRA.
For more information please contact CRA and Revenu Quebec.
