📅 Corporate Tax Deadlines: Is Your Business on Track?
Missing a corporate filing deadline can mean costly penalties and interest! Here’s what every Canadian corporation needs to know: ⏰
T2 Corporate Tax Return:
📌 Due: 6 months after fiscal year-end
Tax Payment Deadline:
📌 Most corporations: 2 months after year-end
📌 CCPCs claiming small business deduction: 3 months after year-end
Other important deadlines:
📌 GST/HST - Quarterly: 1 month after quarter-end | Annual: 3 months after year-end
📌 Payroll Remittances - Monthly, based on remitter type
📌 T4 Slips - February 28 (following calendar year)
📌 T5 Slips - February 28 (following calendar year)
⚠️ Important note:
The T2 FILING deadline and the TAX PAYMENT deadline are different! You could file on time but still face interest charges if payment is late.
Why this matters:
Late filing penalties start at 5% of unpaid tax, PLUS 1% for each additional month late (up to 12 months)!
Never miss a deadline again!
