In case of income tax on the payroll earned by the employees, there exists a mechanism of tax deduction at source. Under this mechanism, the employer who employs the individuals on payroll is required to deduct the tax from payroll of the employees at the time the payment is made. The employer is responsible to deduct and remit the tax on payroll to the government.
Can this be claimed as a deduction on Ontario income tax return as the employer has NOT included it in Box 22 on the T4 slip.
I called CRA Agent ID 201603PAC who was no help at all.
