Are the RL-1 and T4 filed together?

No. The T4 goes to the CRA, the RL-1 to Revenu Québec. Each gets its own confirmation number, which is precisely why they count as two distinct tasks.

Is an RL-1 required for an employee outside Quebec?

The RL-1 covers remuneration tied to a Quebec establishment. An employee attached to an establishment in another province receives a T4 without an RL-1.

Revenu Québec Rule to confirm

RL-1 slip filing deadline

The last day of February for the preceding calendar year.

This rule could not be verified. The Revenu Québec, Enterprise Registrar and CNESST sites refuse automated access: the rule above reflects my understanding without having been checked against an official text. Confirm it with Revenu Québec before relying on it.

Who it applies to

Every employer who paid remuneration to an employee of a Quebec establishment. The RL-1 is the Quebec equivalent of the T4: two distinct filings, same deadline.
