Every corporation resident in Canada must file a T2 Corporation Income Tax Return for each tax year, whether or not any tax is owing, and for tax years beginning after 2023 most corporations have to file it electronically. The T2 corporation income tax return filing requirements cover who files, what schedules go with it, when the return and the payment are each due, and what the CRA charges when either one is late. The rules below apply to the return itself; the tax rates that determine what you owe are a separate question.
Which Corporations Have to File
Every resident corporation in Canada must file a T2 for each tax year, regardless of whether tax is owed. That obligation extends to non-profit organizations, tax-exempt corporations, and inactive corporations with no operations during the year.1Canada Revenue Agency. Corporation Income Tax Return A dormant corporation that did nothing all year still owes the CRA a return. Skipping filings while inactive can trigger penalties and eventually lead to dissolution.
Non-resident corporations file a T2 if, at any time in the year, they carried on business in Canada, realized a taxable capital gain, or disposed of taxable Canadian property.2Canada Revenue Agency. T2 Corporation – Income Tax Guide – Before You Start
Only a narrow set of entities is exempt: tax-exempt Crown corporations, Hutterite colonies, and registered charities.1Canada Revenue Agency. Corporation Income Tax Return Outside those categories, the T2 is universal.
Mandatory Electronic Filing
For tax years starting after 2023, corporations must file the T2 electronically. The exceptions are insurance corporations, non-resident corporations, corporations reporting in a functional currency other than Canadian dollars, and corporations exempt from tax under section 149 of the Income Tax Act.1Canada Revenue Agency. Corporation Income Tax Return A corporation that doesn’t qualify for an exemption but files on paper anyway is charged a $1,000 penalty.
The rule reaches tax preparers too. Anyone preparing more than five corporate returns for compensation in a calendar year must file those returns electronically.3Justice Laws Website. Income Tax Act RSC 1985 c 1 5th Supp – Section 150.1 Corporations that do qualify for a paper-filing exemption mail the return to the CRA tax centre designated for their geographic region.
What You Need Before You Start
You’ll need the corporation’s nine-digit Business Number (BN), which the CRA assigns when you first register and uses for every federal tax account.4Canada Revenue Agency. Business Number and CRA Program Accounts You also need to know the corporation’s classification. Whether it’s a Canadian-controlled private corporation (CCPC), a public corporation, or another type drives which rates and deductions apply on the return.
Financial data goes on the T2 through the General Index of Financial Information (GIFI), a standardized list of codes that maps to your balance sheet and income statement line items.5Canada Revenue Agency. General Index of Financial Information (GIFI) The GIFI is how the CRA reads your financials in a consistent format.
Most corporations file several schedules with the main return. Schedule 1 reconciles the net income on your financial statements to your net income for tax purposes, capturing every adjustment between accounting profit and taxable income.6Canada Revenue Agency. T2SCH1 Net Income (Loss) for Income Tax Purposes Other schedules cover specific credits and deductions; Schedule 21, for example, is where resident corporations and authorized foreign banks claim federal foreign income tax credits.7Canada Revenue Agency. T2SCH21 Federal and Provincial or Territorial Foreign Income Tax Credits and Federal Logging Tax Credit
When the T2 Short Return Applies
Some corporations qualify for the T2 Short Return, a two-page version of the full nine-page form.8Canada Revenue Agency. T2 Short Return Two categories can use it: a CCPC reporting nil net income or a net loss, and a corporation exempt from tax under section 149 (such as a non-profit). Either way, the corporation must also meet additional conditions, including being established in only one province or territory, not claiming refundable tax credits, not having paid or received taxable dividends, and reporting in Canadian dollars. Anything more complex means the full T2.
Filing Deadline and Payment Deadline Are Not the Same
A corporation’s tax year is its fiscal period, which cannot exceed 53 weeks (371 days).9Canada Revenue Agency. Determining Your Corporations Tax Year The T2 is due no later than six months after the last day of that fiscal period.10Canada Revenue Agency. Fiscal Period for Income Tax Purposes A December 31 year-end means a June 30 filing deadline.
Any tax owing is due earlier. Most corporations must pay the balance within two months of their fiscal year-end. A CCPC that claimed the small business deduction and whose taxable income together with any associated corporations stayed within the business limit gets an extra month, so its balance is due three months after year-end.11Canada Revenue Agency. Balance-Due Day Six months to file and two or three months to pay are separate dates, and both matter. Interest can run on unpaid tax well before the return itself is late.
Instalment Payments During the Year
Most corporations can’t wait until balance-due day and settle up all at once. The Income Tax Act requires instalment payments through the year, in the same way employees have tax deducted from each paycheque.12Canada Revenue Agency. Corporation Instalment Guide 2025 The default schedule is monthly.
Small CCPCs with a perfect compliance history, taxable income of $500,000 or less, and taxable capital employed in Canada of $10 million or less can pay quarterly.12Canada Revenue Agency. Corporation Instalment Guide 2025 Perfect compliance means every GST/HST remittance, payroll withholding, CPP contribution, and EI premium was on time in the past 12 months, and every required return was filed on time.
You’re exempt from instalments entirely if the total federal tax payable is $3,000 or less for either the current or previous tax year. New corporations in their first year of operation are also exempt and simply pay what they owe by the balance-due day.12Canada Revenue Agency. Corporation Instalment Guide 2025
Penalties for Filing Late
The basic late-filing penalty is 5% of the unpaid tax that was due on the filing deadline, plus 1% for each complete month the return remains outstanding, up to 12 months.13Canada Revenue Agency. Avoiding Penalties On a $50,000 balance, that’s $2,500 the day you’re late, plus another $500 for every complete month after.
Repeat offenders pay more. If the CRA issued a demand to file and the corporation was already assessed a late-filing penalty in any of the three previous tax years, the rate doubles to 10% of the unpaid tax plus 2% per complete month, for up to 20 months.13Canada Revenue Agency. Avoiding Penalties That can reach 50% of the unpaid balance. Interest also accrues on any outstanding amount from balance-due day, compounding daily at the CRA’s prescribed rate.
Separately, a corporation that was required to file electronically but submitted a paper return faces a flat $1,000 penalty on top of any late-filing penalty.1Canada Revenue Agency. Corporation Income Tax Return
The Notice of Assessment and Fixing Errors
Once the CRA processes the return, it issues a notice of assessment, delivered either through My Business Account (if you’re signed up for online mail) or by regular mail.14Canada Revenue Agency. After You File Your Corporation Income Tax Return The notice confirms the final tax liability and flags any adjustments the CRA made to the figures you reported.
If you find an error or omission after assessment, you request a reassessment rather than filing a new T2. The fastest route is commercial tax preparation software that supports electronic reassessment requests.15Canada Revenue Agency. Requesting a Reassessment of Your T2 Return
You can also write to the tax centre that serves your corporation. Include the corporation’s name, Business Number, the tax year in question, and a clear explanation of the changes, along with any revised financial statements or schedules. Do not resend the entire T2.15Canada Revenue Agency. Requesting a Reassessment of Your T2 Return
To carry back a loss or credit to a prior year, file the applicable schedule (Schedule 4 for losses, Schedule 21 for foreign tax credits on business income, Schedule 31 for investment tax credits) either with the current-year return or separately to your tax centre.
How Long to Keep the Records
After filing, you must keep all supporting records for at least six years from the end of the last tax year they relate to.16Canada Revenue Agency. Where to Keep Your Records That covers invoices, bank statements, receipts, payroll records, GIFI working papers, and anything else supporting numbers on the return. The six-year clock restarts for each tax year, so you’ll always be holding multiple years at once.
If a corporation dissolves, records must be kept for two years after the dissolution date. When corporations amalgamate, the new entity inherits the record-keeping obligations and must retain each predecessor’s records for the full six-year period.16Canada Revenue Agency. Where to Keep Your Records Destroying records early without CRA permission can leave you unable to substantiate a deduction years later when an audit arrives.
