T4, T4A and T5 slip deadlines
T4, T4A and T5 slips and their summaries for 2026 are due the last day of February 2027, and the slips go to the people they're for by the same day. When that's a weekend, they're on time the next business day.
The dates in 2027
| What's due | Due |
|---|---|
| T4 slips & summary — 2026 | Weekend: on time by Monday, March 1 |
| T4A slips & summary — 2026 | Weekend: on time by Monday, March 1 |
| T5 slips & summary — 2026 | Weekend: on time by Monday, March 1 |
| T5013 partnership return — year ending Dec 31, 2026 | |
| T5018 return — year ending Dec 31, 2026 |
The T5018 is due six months after the end of its reporting period: the calendar year here, or the fiscal year if that's the one the business reports on. The T5013 partnership return is due March 31 when all the partners are individuals, five months after the year-end when they're all corporations, and the earlier of the two otherwise.
