Corporate Tax Deadlines
Corporate tax return deadlines depend on your corporations fiscal year-end. Generally, corporations must file within six months of their fiscal year-end. For example, if your fiscal year ends on December 31, 2025, your return is due by June 30, 2026.
GST/HST Filing Deadlines
GST/HST returns are typically due one month after the end of your reporting period. For annual filers, the deadline is usually three months after your fiscal year-end. Quarterly filers must submit returns within one month of each quarter-end.
