Deadlines and follow-ups
Quebec trade rule for accountants and tax specialists.
The rule
facts, not advice: For the 2025 tax year, the Canada Revenue Agency (Agence du revenu du Canada, ARC) set April 30, 2026 as the filing and payment deadline, and June 15, 2026 as the filing deadline for a self-employed person or their spouse or common-law partner; payment was still due April 30. Leo reminds clients of the dates and of the list of documents that your firm approves, for the ARC as well as for Revenu Québec, and never says what to declare. As for text messages, a request for documents for an ongoing engagement does not require prior consent (Canada's Anti-Spam Legislation, Loi canadienne anti-pourriel, CASL/LCAP, art. 6(6)b)); a promotion does (art. 10(9)a)).
