Corporate Tax Return (T2): A Step-by-Step Guide

Filing a T2 (corporate income tax return) is one of the most important responsibilities for incorporated business owners in Canada. Here's what you need to know.

What is a T2?

A T2 is the federal corporate income tax return required for all Canadian corporations. Provinces also require separate corporate returns.

T2 Deadlines

Filing Deadline: 6 months after your fiscal year-end
Payment Deadline: 2 months after fiscal year-end (for quarterly installments)

Key Information Required

• Corporate identification
• Financial statements (Balance Sheet, Income Statement)
• Schedule of income and deductions
• Detail of non-deductible expenses
• Dividend information
• Shareholder information

Major Tax Deductions for Corporations

• Salaries and wages
• Rent and occupancy costs
• Office supplies and equipment
• Vehicle and transportation
• Professional fees
• Interest on business loans
• Depreciation (Capital Cost Allowance)

Small Business Tax Rate

Canadian corporations benefit from reduced tax rates on the first $500,000 of active business income. The federal rate is typically 11.5-19%, with provincial rates varying.

Dividend Tax Credit

Corporations can pay dividends to shareholders. The dividend tax credit system ensures income isn't double-taxed at corporate and personal levels.

Common T2 Mistakes

• Missing deadlines
• Incomplete financial statements
• Incorrect deductions
• Improper dividend declarations
• Not tracking corporate vs. personal expenses
