When Canada’s 2026 T4 information return is due

Start with the reporting year

A T4 slip records employment remuneration paid during a calendar year. The return for the 2026 calendar year follows the annual rule based on the last day of February 2027. Source 4 Source 1

The weekend moves the ordinary deadline

The calendar says a return is on time if the CRA receives it, or it is postmarked, by the next business day when the due date falls on a weekend or a recognized public holiday. Sunday 28 February 2027 moves the ordinary date to Monday 1 March. Source 1

A business closure can shorten the period

The employer guide gives a 30-day filing period from when a business stops operating and a 90-day period from the death of a partner or sole proprietor. An individual employee leaving does not change the annual filing deadline. Source 2

The filing method is a separate requirement

CRA says more than five information slips of the same return type generally require electronic filing. Payroll remittance dates follow separate rules. The T4 deadline covers the annual information return. Source 3 Source 1
