T4

The T4, Statement of Remuneration Paid, is issued by every employer that paid salary, wages, commissions, bonuses, vacation pay, taxable benefits or other remuneration to an employee, or that deducted tax, CPP or EI from those amounts. An employee with more than one employer, or who changed jobs, receives a separate T4 from each.
