T4 Slip

Canadian year-end slip reporting employment income and key payroll deduction totals for an employee.

T4 Slip

A T4 slip is the Canadian year-end payroll slip that reports employment income and key payroll deduction totals for an employee.

It plays a role similar to the U.S. W-2, but it belongs to Canadian payroll and tax reporting. Payroll builds it from year-to-date records created over the full year, not from a single pay period.

Why It Matters

The T4 matters because it is where payroll totals become the employee’s year-end reporting document. If payroll records are wrong during the year, the T4 is one of the clearest places the problem shows up.

It connects:

  • employment income
  • source deductions
  • employer year-end filing

Where It Appears In Payroll Workflow

The T4 is prepared after year end from payroll registers, year-to-date balances, and year-end reconciliation work. It is not a replacement for the pay stub.

  • a pay stub shows one payroll period
  • a T4 summarizes the payroll year

Payroll staff may compare payroll registers, source-deduction totals, and year-end summaries before issuing the slip.

Practical Example

An employee receives regular pay stubs throughout the year. After year end, payroll totals the year’s employment income and deduction records, then issues a T4 slip based on those annual figures.

That makes the T4 a year-end reporting document, not a run-by-run payroll record.
