Tohme Accounting has been helping incorporated businesses in Ottawa and Toronto navigate Canada’s corporate tax return requirements since 2011. Every Canadian corporation must file a T2 with the CRA each year, even if no income was earned. This guide covers who must file, key deadlines, required schedules, how to pay, and what to watch for before you submit.
Who Must File a Corporate Tax Return in Canada?
Every corporation resident in Canada must file a T2 return for each tax year, regardless of income level. This includes CCPCs, holding companies, shelf corporations, dormant companies, and non-profit entities that are not registered charities. Non-resident corporations must also file if they carried on business in Canada or disposed of taxable Canadian property. The only exemptions are specific Crown corporations, Hutterite colonies, and registered charities. Filing a nil return for an inactive corporation is mandatory, not optional, and failure to do so can result in penalties if a balance is later assessed on reassessment. Understanding who must file a corporate tax return in Canada is the starting point for every newly incorporated business.

T2 Filing Deadlines: When Is Your Corporate Tax Return Due?

The T2 return is due six months after the end of the corporation’s fiscal year. A December 31 year-end means a June 30 filing deadline. A March 31 year-end means a September 30 deadline. The fiscal year-end is fixed at the time of incorporation and cannot be changed without CRA approval. For tax years starting after 2023, electronic filing is mandatory for most corporations, and the CRA charges a $1,000 penalty for non-compliance. T4s and other information slips carry earlier deadlines and must not be confused with the T2 filing date. For more on this topic, see our guide on avoiding CRA audit triggers.
Corporate Tax Payment Deadlines: When Is the Balance Due?
The payment deadline arrives earlier than the filing deadline, and this distinction matters. Most CCPCs eligible for the Small Business Deduction must pay any balance owing within three months of their fiscal year-end. All other corporations must pay within two months. Installments are required when the prior-year tax payable exceeds $3,000, and missing an installment triggers CRA interest, even if the T2 is filed on time later. Payment is made to the Receiver General via CRA My Business Account, online banking, or pre-authorized debit. Tax owing generally must be remitted before the return is filed.
What’s Inside a T2 Return: Key Schedules Explained
The T2 is a nine-page return supported by additional schedules that document your corporation’s financial position in detail. GIFI codes standardize the presentation of financial statements for CRA review. Schedule 1 reconciles book income to taxable income. Schedule 8 tracks capital cost allowance claims. Schedule 4 documents loss continuity for carryforward or carryback. Schedules 100 and 125, covering the balance sheet and income statement, respectively, are required for every filing. Schedule 11 captures transactions between the corporation and its shareholders. Understanding which schedules apply to your situation is one of the most common sources of error when filing a corporate tax return in Canada.
Provincial Corporate Tax Filing: Federal T2 vs. Separate Returns




For most provinces and territories, the federal T2 serves as both the federal and provincial return. CRA collects and remits provincial tax on the province’s behalf under Tax Collection Agreements. Ontario falls under this arrangement. However, Quebec requires a separate CO-17 return filed directly with Revenu Québec, and Alberta requires a separate AT1 return filed with Alberta Tax and Revenue Administration. Corporations operating across multiple provinces must allocate income using Schedule 5. This provincial filing distinction is one of the most frequently overlooked compliance points for incorporated businesses expanding beyond a single province.
T2 Short Return: When Can You Use the Simplified Version?
The T2 Short Return is a two-page alternative to the full nine-page T2. It is available only to certain eligible CCPCs that had no net income or loss during the year and satisfy the conditions outlined in CRA Guide T4012. Dormant corporations that meet these criteria may qualify. Electronic filing remains mandatory regardless of which form is used. Most active businesses, including those with any revenue, expenses, or shareholder activity, must file the full T2 with all applicable schedules. If you are uncertain whether your corporation qualifies for the short form, reviewing the CRA guide or consulting a CPA before filing is the safer path.
Common T2 Mistakes That Attract CRA Attention
Misclassifying personal expenses as corporate expenses is the most frequently observed trigger for CRA review. Shareholder benefits, including personal vehicle use and housing costs routed through the corporation, must be reported as taxable benefits on T4 slips. GIFI code errors create automatic flags during CRA’s processing. Inconsistent fiscal year-end dates raise administrative concerns. Unreported related-party transactions on Schedule 9 have become an increasing focus of audits. A pre-filing review by a CPA resolves the majority of these issues before they reach the CRA’s attention. Small errors in these areas can generate correspondence that takes months to resolve, even when the underlying position is correct. These are among the most consequential mistakes incorporated businesses make when managing their corporate tax return in Canada.

How to Pay Your T2 Corporate Tax Balance
Corporate tax balances are remitted to the Receiver General for Canada. The most common methods are CRA My Business Account using online banking bill payment, My Payment via Interac or Visa Debit, and pre-authorized debit. Wire transfers are accepted. Cheques are not recommended due to delays in delivery and processing. Interest accrues at the CRA-prescribed rate from the balance-due date, regardless of when the return is filed, so late payment carries a real cost even if the return is filed on time. Installment payments made throughout the year are credited against the final balance owing at year-end.
CCPC Advantages: How the Small Business Deduction Affects Your T2




For eligible CCPCs, the federal Small Business Deduction reduces the standard 15% federal corporate rate to 9% on the first $500,000 of active business income. This deduction is claimed directly on the T2 and requires documentation confirming CCPC status throughout the year. Passive income above $50,000 in adjusted aggregate investment income reduces SBD eligibility on a sliding scale, a rule that affects corporations with significant retained investment income. Associated corporations share the $500,000 limit and must coordinate their claims accordingly. Properly claiming the Small Business Deduction is one of the more consequential decisions in T2 preparation, with a material impact on annual tax payable. Businesses with passive income should review eligibility carefully as part of year-end planning.

Frequently Asked Questions
When is the T2 corporate tax return due in Canada?
The T2 return is due six months after the end of your corporation’s fiscal year. For a December 31 year-end, that deadline is June 30 of the following year. For a March 31 year-end, it is September 30. The corporate tax deadline for paying any balance owing arrives earlier: most corporations must pay within two months of year-end, and CCPCs eligible for the Small Business Deduction have three months. Electronic filing is mandatory for tax years starting after 2023, and the CRA charges a $1,000 penalty for non-compliance.
Does every corporation in Canada have to file a T2?
Yes. All corporations resident in Canada must file a T2 each tax year, including dormant companies, holding corporations with no revenue, and non-profit entities that are not registered charities. Non-resident corporations must also file if they carried on business in Canada or disposed of taxable Canadian property. The only exemptions are specific Crown corporations, Hutterite colonies, and registered charities. Filing a nil return for an inactive corporation is mandatory. Failure to file, even when no tax is owing, can result in penalties if the CRA later reassesses a balance.
Can I file my own T2 corporate tax return without a CPA?
There is no legal requirement to use a CPA to file a T2. Corporations can prepare and file their own returns using CRA-certified software. However, the T2 involves GIFI-coded financial statements, multiple schedules, and calculations that affect tax payable and CRA compliance. Errors in capital cost allowance, shareholder benefits, or CCPC eligibility can produce assessments, interest, and penalties. For corporations with shareholders, salary-dividend decisions, or passive income, professional preparation generally costs far less than resolving the downstream issues that arise from errors in those areas.
What happens if I file my T2 late?
A late-filed T2 results in a CRA penalty of 5% of the unpaid balance, plus 1% per month for up to 12 additional months. If the CRA issued a formal demand to file and the corporation did not comply, the penalty doubles. Interest accrues on unpaid amounts from the payment-due date, not the filing date. Repeated late filings increase scrutiny of future returns. Filing on time, even when the full balance cannot be paid, always reduces the total cost. A payment arrangement with the CRA is preferable to allowing interest to compound on an unfiled balance.
What is the difference between the T2 and the T2 Short Return?
The full T2 Corporation Income Tax Return is a nine-page form required for most corporations. The T2 Short Return is a simplified two-page version available only to certain eligible CCPCs that had no net income or loss during the year and satisfy the conditions outlined in CRA Guide T4012. Both must be filed electronically for tax years starting after 2023. Most active businesses, including any corporation with revenue, deductible expenses, or shareholder activity during the year, must file the full T2 with all applicable schedules attached.
How long should I keep my T2 records after filing?
The CRA requires corporations to retain all records and supporting documents related to a T2 filing for a minimum of 6 years from the end of the last tax year to which those records relate. This includes financial statements, invoices, bank records, payroll summaries, shareholder resolutions, and any documents supporting deductions or credits claimed on the return. If a formal objection or CRA appeal is in progress, records must be kept until the matter is fully resolved. Disposing of records before the retention period has passed creates unnecessary risk if a reassessment or review is initiated later.
