What Is a T2 Corporate Tax Return and When Is It Due

Every corporation in Canada — including your Calgary incorporated business — must file a T2 Corporate Income Tax Return with CRA every year, even if the corporation had no income or was inactive. Here is a straightforward guide to what the T2 is, when it's due, and what's involved.

What Is a T2 Return?

The T2 is the annual income tax return for corporations. It reports the corporation's income, deductions, and tax owing for the fiscal year. Unlike personal tax returns, which always cover the calendar year, a T2 covers your corporation's fiscal year — which can end on any date you choose when incorporating.

When Is the T2 Due?

Your T2 return is due six months after the end of your fiscal year. If your fiscal year ends December 31, 2025, your T2 is due June 30, 2026. If your year ends March 31, 2026, it's due September 30, 2026. However, any tax balance owing is due two or three months after year-end (depending on your corporation's size), regardless of the filing deadline.

What's Included in the T2?

The T2 package includes the main return plus various schedules. Key components include: Schedule 1 (net income reconciliation), Schedule 8 (Capital Cost Allowance), Schedule 50 (shareholder information), and financial statements. Most T2s must be filed electronically, and professional tax software is typically required to prepare them.

Penalties for Late Filing

If you file late and owe tax, CRA charges a penalty of 5% of the unpaid tax plus 1% per month for up to 12 months. If you've been penalised for late filing in a recent year, the penalty doubles to 10% plus 2% per month. These penalties add up quickly.

Can You Prepare Your Own T2?

Technically yes, but the T2 is significantly more complex than a personal return. Most Calgary business owners have their accountant prepare the T2 using the financial statements provided by their bookkeeper. Accurate, complete bookkeeping is the foundation of an accurate T2.
