T2 Corporation Return Guide: Schedules, Deadlines and Penalties for 2026

The T2 corporation return is the annual income tax return that every corporation resident in Canada files with the Canada Revenue Agency (CRA), including companies that earned nothing or owe no tax. It reports the corporation's income for its fiscal year, calculates federal tax and, outside Quebec and Alberta, provincial tax, and carries a set of schedules that explain the numbers. This guide is for owners and finance leads, including those with U.S. or India-linked shareholders, who need to know what goes into the return and when it is due.

Who must file a T2 corporation return?

All corporations resident in Canada must file, including non-profit, tax-exempt and inactive ones; the exceptions are tax-exempt Crown corporations, Hutterite colonies and registered charities. Certain non-resident corporations file in some situations. The CRA also offers a two-page T2 Short Return, plus Schedule 1, for a CCPC with nil net income or a loss for tax purposes (and for certain exempt corporations). Alberta and Quebec corporations file a separate provincial return as well, the AT1 and the CO-17.

The corporate tax year is the fiscal period in the financial statements, which need not be the calendar year. A first-year corporation also attaches Schedule 101, Opening Balance Sheet Information, and copies of agreements for any shares issued for non-cash consideration.

How to file a T2 corporation return, step by step

1. Close the books for the fiscal year and prepare financial statements.
2. Convert them to GIFI. Schedule 100 carries the balance sheet, Schedule 125 the income statement and Schedule 141 questions about who prepared the statements. Inactive corporations without balance sheet or income statement data may skip these.
3. Adjust accounting profit to taxable income on Schedule 1, with capital cost allowance on Schedule 8, capital gains on Schedule 6 and loss carry-forwards on Schedule 4.
4. Test associations and the small business limit. Schedule 9 lists related and associated corporations and Schedule 23 allocates the $500,000 business limit; Schedule 7 handles passive income. See the small business deduction guide.
5. Complete the provincial tax calculation. Outside Quebec and Alberta, report provincial tax on line 760 of the T2, using Schedule 5 if it is required.
6. Add the shareholder and non-resident schedules listed below.
7. File electronically with CRA-certified software and pay any balance by the balance-due date.

Which schedules appear most often?

Related-party dealings with non-residents add Schedule 19 (non-resident shareholders), Schedule 29 (payments to non-residents), Form T106 if reportable transactions with non-arm's-length non-residents exceed $1,000,000, Form T1135 if specified foreign property cost passes CAN$100,000, and Form T1134 for foreign affiliates. See our T1135 guide and T1134 guide.

When is the T2 due, and when is the tax due?

File within six months of the end of the tax year. If the year ends on the last day of a month, the due date is the last day of the sixth month after it. A weekend or CRA-recognized holiday moves the date to the next business day. The tax balance is due two months after year-end, or three months when the corporation was a CCPC throughout the year, claims the small business deduction (or did last year) and prior-year taxable income stayed within its business limit. Most corporations also pay instalments each month, or each quarter if they are an eligible small CCPC. You must file no later than three years after a tax year to receive a refund.

Form T106, where required, is due six months after year-end, and Form T1134 ten months after year-end. The CRA deadline calendar shows both with other dates.

What are the penalties?

Interest on unpaid tax is charged daily at the prescribed rate. Our CRA penalties and interest guide covers relief requests.

Worked example: a Hamilton CCPC with a December 31 year-end

Northfield Components Ltd. is a Hamilton CCPC. It claimed the small business deduction last year with taxable income inside its business limit. For its 2026 year it owes $20,000 of tax. The balance is due March 31, 2027, three months after year-end, and the T2 is due June 30, 2027. If the return is filed on October 5, 2027, which is three complete months late, and the $20,000 is still unpaid on the filing deadline, the penalty is 5% ($1,000) plus 3% ($600), or $1,600, plus interest. Had the company paid by March 31, 2027, there would be no late-filing penalty even if the return were a few days late, because the penalty is a percentage of unpaid tax.

Mistakes to avoid

• Skipping the T2 for an inactive or newly formed company.
• Treating the provincial annual return or federal corporate annual return as the tax return.
• Forgetting Schedule 50 or Schedule 9 and mis-stating the business limit.
• Paying the balance on the filing date instead of the earlier balance-due date.
• Missing T106 or T1135 because the form lives outside the T2 package.

A note for U.S.- and India-linked owners

If a U.S. person owns a Canadian corporation, the T2 figures feed their U.S. information returns; our foreign business reporting guide explains how, and the two filings should use consistent year-ends and accounting records. Indian shareholders should expect Schedule 19 disclosure and possible withholding on dividends; see India-Canada business structures and foreign asset reporting across the three countries. Indian owners can start with India FDI and FEMA reporting for the reporting framework on their side.
