Do You Need Corporate Tax Filing for Your Incorporated Business?
Every incorporated business in Canada must file a T2 corporate income tax return every year, regardless of whether the corporation earned income or not. Missing it creates late filing penalties that compound quickly, and CRA does not make exceptions for small corporations that simply forgot.
With 17 plus years of tax and accounting experience behind the firm, Acctax prepares T2 returns for incorporated businesses across Ontario. We review your year-end financials, handle the schedules, keep you CRA-compliant, and explain your results in plain language after filing.

What Does Our Corporate Tax Filing Service Include?
A T2 return involves more than a single form. Depending on your corporation’s structure and activity during the year, the filing can include multiple schedules, GIFI-coded financial statements, payroll reconciliations, and GST/HST coordination. Here is what we cover.
T2 Return Preparation
We handle the complete preparation of your T2 return, including all required schedules.
Year-End Financial Review
We review your financial documents for accuracy and tax implications before filing.
CRA Schedule Support
We prepare and review all required schedules, disclosures, and attachments.
Expense and Deduction Review
We identify eligible deductions and review your expense records against CRA requirements.
GST/HST and Payroll Coordination
We coordinate GST/HST filings and payroll reconciliations alongside the T2 where applicable.
CRA Filing Confirmation
We confirm direct filing with CRA and provide confirmation of submission once accepted.
Who Needs to File a Corporate Tax Return?
Any business that has incorporated in Canada is legally required to file a T2 return each year. The filing obligation exists whether the corporation made money, broke even, or had zero activity for the entire year.
The corporations we file for most often include active corporations, inactive corporations, professional corporations such as those used by doctors, lawyers, and accountants, small incorporated businesses, holding companies, and corporations with CRA notices requiring a response alongside their return.
What Corporate Tax Documents Do You Need to Provide?
Organized records make the entire process faster and reduce the chance of errors or CRA follow-up. Bringing everything together before preparation starts saves time on both sides.
Financial Records
Year-end financial statements, trial balance and general ledger, bank reconciliations, and shareholder loan details.
Other Important Documents
Payroll summaries, GST/HST records, corporate/personal income records, and prior-year T2 return and Notice of Assessment.
How Does the Corporate Tax Filing Process Work?
From the moment you send us your documents to the point CRA confirms your filing, the process runs in seven clear stages. Nothing gets submitted without your review and sign-off first.
Review Filing Scope
We confirm what type of return is needed and identify any outstanding CRA matters before preparation begins.
Collect Financial Records
You provide your year-end financials, bank statements, and any relevant corporate records through our secure portal or in person.
Check Missing Information
We review your documents, flag anything missing or unclear, and follow up before preparation starts rather than after.
Prepare T2 Return
We prepare the full T2 return including all applicable schedules, GIFI financial statements, and supporting calculations.
Review With You
We walk you through the return summary, explain the tax payable or refund position, and answer any questions before asking for approval.
Submit to CRA
We file electronically through CRA’s EFILE program and receive a confirmation number once CRA accepts the return.
Post-Filing Support
We review your Notice of Assessment when it arrives, flag any discrepancies, and prepare a response if CRA requests additional information.
When Is a Corporate Tax Return Due?
Missing your T2 deadline triggers penalties that start immediately and grow the longer the return stays unfiled. Here are the dates that matter for your corporation.
Return Due 6 Months After Year-End
CRA requires your T2 return within six months after your corporation’s fiscal year-end. A December 31 year-end means a June 30 filing deadline.
Balance Owing Due Date
Any corporate tax balance owing is due within two months after your fiscal year-end for most corporations, or three months if the corporation qualifies for the extended deadline.
Weekend or Holiday Due Date
When a filing or payment deadline falls on a weekend or holiday, CRA moves it to the next business day.
Late Filing Is Costly
You can still file after the due date, but late filing penalties and interest begin accumulating immediately on any balance owing.
What Happens If Corporate Tax Filing Is Late or Incorrect?
Late or inaccurate T2 filings create problems that take considerably more time and money to fix than the original filing would have cost. Here is what CRA applies.
Electronic Filing Requirements
Corporations with gross revenues above $1 million are required to file electronically. Non-compliance can add to penalties.
CRA Questions or Reassessments
Errors or missing information in a T2 return increase the likelihood of CRA review, audit, or reassessment.
Importance of Complete Records
Incomplete records at the time of filing increase the risk of errors and make responding to any CRA follow-up considerably harder.
How Much Does Corporate Tax Filing Cost?
Pricing is based on the complexity of your corporation’s return, the volume of transactions, and whether GST/HST, payroll, or CRA correspondence is involved alongside the T2.
Simple T1 Return
Inactive corporations or simple returns with limited transactions
Standard Corporate Filing
RecommendedActive corporations with standard income, expenses, and deductions
Complex / Specialized Filing
Corporations with multiple income streams, related parties, or specialized filing needs

FAQs
No. A personal tax return uses the T1 form and reports individual income. A T2 corporate return is a separate filing for the corporation itself and covers the corporation’s income, deductions, and tax payable for the fiscal year.
The T1 is for individuals. The T2 is for corporations. They are completely separate filings with different forms, deadlines, and CRA accounts.
Yes. We prepare and file outstanding prior-year T2 returns and can help organize the records needed to bring the corporation current with CRA.
Yes. We coordinate GST/HST filings and payroll remittances alongside the T2 where applicable so the full compliance picture is managed together.
Yes. CRA charges a late filing penalty of 5% of unpaid tax owing plus 1% per month the return remains outstanding, up to 12 months. Corporations with a history of late filing face higher penalties.
Who Must File a T2 Return in Canada?
Corporations Required to File
Active corporations earning business or investment income
Inactive corporations with no business activity during the year
Non-profit organizations (unless registered charities)
Tax-exempt corporations under specific ITA sections
Holding companies with passive investment income
Professional corporations (doctors, lawyers, accountants, engineers)
Note: The only corporations exempt from T2 filing are registered charities (filing T3010), Crown corporations, and Hutterite colonies.
Common Misconception
“My corporation had no activity, so I don’t need to file.”
Reality: Inactive corporations must file.
Failure to file triggers penalties, and after two years of non-filing, CRA may dissolve your corporation administratively. File every year, even with zeros.
The T2 Return and Ontario Permanent Establishment
Ontario does not require a separate provincial corporate tax return. The T2 Corporation Income Tax Return serves as both the federal and provincial return for corporations carrying on business in Ontario through a permanent establishment.
What Is Permanent Establishment?
A corporation has a permanent establishment in Ontario when it maintains:
- A fixed place of business (office, warehouse, factory, branch)
- Employees or agents acting on behalf of the corporation
- Substantial equipment or inventory stored in Ontario
If your corporation operates from Kitchener, Waterloo, Cambridge, or anywhere in Ontario with a physical presence, you have a permanent establishment. Income allocated to Ontario is taxed at Ontario rates on the same T2 return filed with CRA.
Provincial Allocation (Schedule 5)
Corporations operating in multiple provinces complete Schedule 5 – Tax Calculation Supplementary – Corporations to allocate taxable income based on:
- Gross revenue attributable to each province
- Salaries and wages paid in each province
Ontario-only corporations allocate 100% of income to Ontario. Multi-province corporations split income proportionally, and each province’s rates apply to their respective allocation.
Ontario Corporate Tax Rates (2024–2025)
Current combined federal and provincial rates for corporations.
| Rate Type | Federal | Ontario | Combined |
|---|---|---|---|
| Small Business Rate (CCPC, active business income ≤ $500k) | 9.0% | 3.2% | 12.2% |
| General Rate (income above business limit or non-CCPC) | 15.0% | 11.5% | 26.5% |
Small Business Deduction Eligibility
The small business deduction (SBD) reduces the federal corporate tax rate from 15% to 9% on the first $500,000 of active business income for Canadian-controlled private corporations (CCPCs).
Ontario’s parallel small business deduction reduces the provincial rate from 11.5% to 3.2% on the same $500,000 business limit.
To qualify:
- Corporation must be a CCPC throughout the tax year
- Income must be active business income (not passive investment income)
- Business limit may be reduced if taxable capital exceeds $10 million or aggregate investment income exceeds $50,000
Strategic Consideration
Proper classification of income as active vs. passive directly affects your combined tax rate—12.2% vs. 26.5%. This is where professional preparation pays for itself.
Filing Deadlines vs. Payment Deadlines
These are different dates. Confusing them costs money.
| Deadline Type | When Due | What Happens If Missed |
|---|---|---|
| T2 Filing Deadline | 6 months after fiscal year-end | 5% penalty on unpaid tax + 1%/month (max 12 months) |
| Balance-Due Day (CCPC) | 3 months after fiscal year-end | Interest accrues on unpaid balance |
| Balance-Due Day (General) | 2 months after fiscal year-end | Interest accrues on unpaid balance |
Example: December 31 Year-End
| Corporation Type | Payment Due | Filing Due |
|---|---|---|
| CCPC (qualifying) | March 31 | June 30 |
| Non-CCPC or large CCPC | Last day of February | June 30 |
Critical Distinction
You have 6 months to file the return, but only 2–3 months to pay the tax. Filing on time with an unpaid balance means interest charges. Filing late with any unpaid balance means interest plus penalties.
Instalment Payments
Corporations expecting to owe more than $3,000 in the current year (and that owed more than $3,000 in the prior year) must make monthly instalment payments throughout the year. Instalments are due on the last day of each month.
Failure to make required instalments triggers instalment interest—even if you eventually pay the full balance by the balance-due day.
Mandatory Electronic Filing
For tax years starting after 2023, the CRA requires all corporations to file their T2 returns electronically. Paper returns are no longer accepted for most businesses, with non-compliance carrying a $1,000 penalty.
Exceptions to Mandatory E-Filing
- Insurance corporations filing T2FSR
- Non-resident corporations
- Corporations reporting in functional currency
- Tax-exempt corporations under ITA s.149
How Electronic Filing Works
What We Prepare: T2 Return Components
Corporate tax filing is a package of schedules and calculations. We handle the technical reconciliation from accounting profit to taxable income.
| Schedule | Purpose & Calculation |
|---|---|
| Schedule 1 | Net Income (Loss) for Income Tax Purposes — reconciles accounting income to taxable income. |
| Schedule 3 | Dividends Received, Taxable Dividends Paid, and Part IV Tax Calculation. |
| Schedule 4 | Corporation Loss Continuity and Application. |
| Schedule 8 | Capital Cost Allowance (CCA) — depreciation for tax purposes. |
| Schedule 50 | Shareholder Information — ownership details for private corporations. |
| Sch 100–141 | General Index of Financial Information (GIFI) — standard financial statements. |
What We Need From You
To ensure accuracy and maximize deductions, please provide the following documents:
Year-end financial statements (Income/Balance)
Trial balance and general ledger detail
Bank statements for the full fiscal year
Shareholder loan account records
Dividend declarations and resolutions
Asset purchase/disposal documentation
Prior-year T2 return and Notice of Assessment
Corporate minute book for verification
Filing Timeline
Standard returns are typically filed within 10–15 business days of receiving all required documents. Complex returns involving multiple schedules, inter-company transactions, or SR&ED claims may require additional time.
Reducing Audit Risk
The CRA selects T2 returns for review based on high-risk indicators. Our filing process is designed to proactively address these triggers.
CRA Audit Triggers
- Unusual deductions relative to industry revenue benchmarks
- Shareholder loan balances without repayment documentation
- Inconsistent reporting of capital gains vs. prior years
- Scientific Research (SR&ED) claims without technical logs
- Related-party transactions without arm’s-length pricing
The Acctax Approach
- Documentation of every major deduction and credit claimed
- Reconciliation of accounting profit to taxable income
- Maintenance of audit-defensible files for 6 years
- Direct representation if the CRA requests clarification
- Rigorous review of shareholder and associated accounts
Maximizing Deductions & Credits
T2 Short Return: When It Applies
Some corporations qualify for the simplified T2 Short Return—a two-page filing plus Schedule 1 reconciliation.
Eligibility Requirements
- CCPC status throughout the entire tax year
- Permanent establishment in only one province (Ontario)
- No taxable income OR claiming only the Small Business Deduction
- No refundable tax credits, associated corporations, or dividends
Our Recommendation
Even if eligible, most businesses benefit from full T2 preparation. The “short” form limits your ability to properly document CCA, shareholder loans, and loss carryforwards which are vital for future tax years.
What Happens After Filing
Electronic Filing Timeline
2–4 Weeks
Notice of Assessment
The CRA issues this document confirming your taxable income, tax calculated, and any credits applied. If paper filed (exceptions only), expect 8–16 weeks.
CRA Adjustment Window
90 Days
Right to Object
If the CRA adjusts your return due to mathematical errors or disallowed deductions, you have 90 days from the NOA date to file a Notice of Objection.
Why Professional Corporate Tax Filing?
“Can I file corporate taxes myself?”
Technically, yes—the CRA provides Web Access Codes for self-filers, and modern software handles the transmission. However, corporate tax law is built on reconciliation, not just data entry.
⚠️ Common Self-Filing Gaps
- Schedule 1 Errors: Failing to add back non-deductible items (like 50% of meals or club dues) or misclassifying accounting gains.
- Provincial Allocation: Improperly calculating income earned in Ontario vs. other provinces, leading to incorrect tax rates.
- Passive Income Drag: Missing the “Grind” rules where passive investment income can reduce your Small Business Deduction.
- Loss Carryforwards: Losing track of non-capital losses (20-year limit) or capital losses, leaving future refunds on the table.
✓ The Professional Advantage
- Audit-Defensible Records: Every deduction is mapped back to the General Ledger and supported by CRA-compliant schedules.
- Entity Optimization: Identifying associated corporation rules to ensure your $500,000 Small Business Limit is shared correctly.
- CCA Strategy: Deciding when to take full depreciation vs. “preserving” it for higher-income future years.
- Direct Representation: If the CRA sends a letter, we handle the technical response and provide the electronic confirmation logs.
The “Subsection 15” Trap
A single error in documenting a shareholder loan can trigger ITA Section 15, causing the CRA to include the entire loan amount as personal income on your T1. Without professional reconciliation, you risk converting tax-free corporate capital into highly-taxed personal income by mistake.
The cost of professional filing is typically recovered through avoided penalties, maximized credits, and the elimination of “hidden” tax liabilities.

FAQs
All resident corporations must file a T2 Corporation Income Tax Return for every tax year. This includes active corporations, inactive corporations, non-profit organizations, and tax-exempt corporations. The only exceptions are registered charities (file T3010), Crown corporations, and Hutterite colonies.
The T2 return must be filed within six months after the corporation's fiscal year-end. For a December 31 year-end, the filing deadline is June 30. Payment deadlines differ: generally 2 months after year-end (or 3 months for qualifying CCPCs).
Yes, for tax years starting after 2023. All corporations must file the T2 return electronically through Corporation Internet Filing, except insurance corporations, non-resident corporations, functional-currency filers, and certain tax-exempt corporations.
Yes, using certified software and a Web Access Code. However, accurate Schedule 1 reconciliation, provincial allocation, shareholder loan compliance, and loss tracking require accounting expertise. Professional filing ensures proper deduction claims and audit protection.
No. The T2 Corporation Income Tax Return serves as both the federal and provincial return for Ontario corporations. Corporations with a permanent establishment in Ontario allocate income to Ontario on Schedule 5, and Ontario tax is calculated on the same T2.
Late-filing penalty is 5% of unpaid tax plus 1% per month for up to 12 months. If you filed late in any of the three preceding years, the penalty doubles to 10% plus 2% per month. Interest accrues on unpaid balances from the balance-due day.
The small business deduction reduces the federal corporate tax rate from 15% to 9% on the first $500,000 of active business income for Canadian-controlled private corporations (CCPCs). Combined with Ontario's 3.2% small business rate, CCPCs pay 12.2% on qualifying income—versus 26.5% at general rates.
Electronically filed T2 returns are typically assessed within 2–4 weeks. Paper returns (where permitted) take 8–16 weeks. We provide electronic confirmation of filing within 24 hours of submission.
