Canadian T2 corporate tax guide: who files, deadlines, GIFI, Schedules 1/3/4/7, shareholder loans, owner salaries, dividends, instalments and records.
Your corporation earned money this year. Does it have to file a tax return even if you left all the cash in its bank account? Usually yes. A corporation has tax obligations separate from its owner.
When does a corporation file and pay its tax?
The T2 tax return is due six months after the corporation’s tax year ends. This is a filing deadline, not necessarily the day its tax is payable.
The unpaid federal corporate tax balance is usually due two months after year-end. A three-month balance-due day applies only if the company was a Canadian-controlled private corporation throughout the year, claimed the small business deduction in the current or previous tax year, and meets the prior-year taxable-income/business-limit condition (including associated corporations where relevant).
In Ontario, the combined federal and provincial small-business income tax rate is 11.2% from July 1, 2026 (9% federal plus 2.2% Ontario). The earlier combined rate was 12.2% (9% plus 3.2%). A corporate year crossing July 1, 2026 may need to prorate Ontario rates.
The combined general corporate income tax rate in Ontario is 26.5% (15% federal plus 11.5% Ontario). Small-business deduction eligibility, active versus investment income and shared business limits can change the actual tax.
What Is a T2 Corporate Tax Return?
A T2 is the corporation's income tax return. The business reports income, deductions, adjustments and tax for its own taxation year. A shareholder's personal return is separate, even when one person owns the entire company.
Which Corporate Tax Filing Rules Apply to Your Business?
Find the situation closest to yours below. The answer explains the usual starting point; the detailed rules and exceptions come later.
Your situation | What it means | What to do next |
Corporation had profits | Prepare financial statements and calculate taxable income. | Reconcile the books and tax adjustments. |
Corporation had no operations | A T2 filing obligation may still exist. | Check corporate status and the year-end. |
Owner took money out | Decide whether it was salary, dividend, reimbursement or loan. | Reconcile shareholder payments. |
Company bought equipment | Accounting depreciation and tax CCA may be different. | Keep asset invoices and dates. |
Year-end passed | Filing and payment dates are not necessarily the same. | Calculate both deadlines separately. |
T2 Example: Filing and Payment Deadlines
If a corporation has a December 31 year-end. Its T2 return is generally due by June 30 the next year, but the balance of corporate tax may be due sooner. Waiting until the T2 filing deadline to pay could cause interest. The exact payment deadline depends on the company's circumstances.
How to Prepare a Canadian Corporation Tax Return
Step 1: Close and reconcile the corporate bookkeeping.
Step 2: Prepare financial statements and identify tax adjustments.
Step 3: Review corporate schedules and owner transactions.
Step 4: Calculate payment and filing deadlines, then submit the T2.
Corporate Tax Terms Explained: T2, GIFI and Shareholder Loans
T2: The corporation's annual income tax return.
GIFI: Standard financial-statement codes used in Canadian corporate tax filings.
Shareholder loan: Money the corporation owes its owner, or the owner owes the corporation.
Who must file a T2?
A resident corporation is generally required to file a T2 Corporation Income Tax Return every tax year, including a year with no taxable income or a loss, subject to the specific exceptions and special corporate categories in the law. Incorporating does not replace personal income tax filings of owners. The company has its own business number, legal identity, financial statements and year-end.
An inactive corporation can still have filing duties; nil operations do not always mean nil balance-sheet movements. A corporation carrying business in other provinces or with non-resident connections may need extra schedules, provincial allocation or disclosure forms.
When is the T2 tax return due?
Corporations generally have a tax year tied to their fiscal year-end, not necessarily December 31. The T2 filing deadline is generally six months after the end of the tax year. Example: a December 31, 2026 year-end ordinarily has a June 30, 2027 filing deadline. The tax balance is generally due two months after year-end.
A three-month deadline applies if the corporation was a CCPC for the whole year, claimed the small business deduction this year or last year, and meets the previous-year income test, including any associated corporations.
Thus a timely T2 can still incur late-payment interest. Corporate instalment due dates and eligibility for quarterly payments also need attention.
From bookkeeping to financial statements and GIFI
A T2 return should be supported by complete trial balance, general ledger, bank and credit-card reconciliations, accounts payable and receivable listings, asset register and ownership/loan balances. Accounting income does not equal taxable income. The General Index of Financial Information (GIFI) classifies statement of financial position and income statement items in the tax return.
Misclassifying a shareholder advance as sales or an asset as an expense can distort both the corporate tax result and owner's personal return. At year-end, reconcile the HST account, payroll deductions, shareholder loan, fixed assets, retained earnings and intercompany balances before preparing tax schedules.
Schedule 1: accounting profit is not taxable profit
Schedule 1 generally reconciles the corporation's net income under accounting rules to net income for income tax purposes. Book depreciation, non-deductible expenses and timing differences can require add-backs or tax deductions. Capital Cost Allowance replaces accounting depreciation for tax purposes, subject to classes, limits, dispositions and enhanced measures. Income-tax expenses, personal expenses paid by the company, portions of meals/entertainment and certain fines can have specific treatment.
Grants, government assistance, reserves and capital gains can require additional adjustments. A neat profit-and-loss statement is necessary but cannot substitute for the tax reconciliation.
Common schedules and who needs them
Which schedules apply depends on the company. Schedule 3 may report dividends received and paid and related information. Schedule 4 tracks losses and their application. Schedule 7 deals with aggregate investment income and income eligible for the small-business deduction for CCPCs in certain circumstances. Other schedules address capital cost allowance, foreign income, taxable capital, related/associated corporations and provincial or territorial tax.
Don't attach every conceivable schedule by default or omit an unfamiliar one without investigating the underlying transaction. A Schedule 50 shareholder-information requirement or other ownership disclosures may be relevant in particular situations. Keep evidence for each election.
What is the corporate income tax rate in Ontario?
A qualifying CCPC may claim a federal small-business deduction on eligible active business income up to an applicable business limit, while general rates can apply to income outside qualifying limits and passive investment income can face different refundable-tax mechanisms. Ontario provincial corporate tax rates and small-business rules can change by effective date, and associated corporations may share limits.
The business limit may be reduced by taxable capital or passive investment income under applicable rules. It is misleading to multiply all corporate accounting profit by one published 'small-business tax rate.' Build the effective-date calculation from the actual fiscal period and income classifications.
Should a business owner take salary or dividends?
A corporation and its shareholder are separate taxpayers. Salary or bonus is typically an expense to the corporation when properly incurred and deductible, with employer payroll obligations and T4 reporting. Dividends follow corporate-law declarations, after-tax earnings concepts and shareholder T5 reporting, with the individual's dividend gross-up and credit system.
Money advanced to or from shareholders requires a properly reconciled loan account; shareholder-loan inclusions and repayment exceptions can apply.
Calling a transfer an 'owner draw' does not make it tax-free. A salary-versus-dividend comparison should consider CPP, RRSP room, personal credits, cash-flow timing and corporate taxable income—not only headline marginal rates.
Capital assets, losses and investment income
Corporate losses may have carryback or carryforward treatment under their own rules; eligibility can change after acquisition of control. Capital gains and losses are tracked separately from ordinary active business profit. Investments held inside a CCPC can create investment-income and refundable-tax consequences, including potential effects on future small-business deduction eligibility. Buying equipment may create CCA but not always an immediate full expense.
Disposing of a business vehicle, computers or equipment can trigger recapture or gains. Shareholder transactions involving assets at below market value can create deemed-value issues. Retain purchase invoices and tax schedules year over year.
HST, payroll and annual corporate requirements
Filing T2 does not satisfy GST/HST returns, source-deduction remittances, T4/T5 slips, corporate annual returns or any sectoral licences. A corporation may also have provincial corporate registry obligations unrelated to tax. Payroll liabilities withheld from staff are trust amounts and should not be treated as working capital.
Some businesses have workers' compensation or employer health tax requirements depending on jurisdiction and thresholds. Corporate records should show directors, shareholders, resolutions and dividend declarations.
A business registered federally but operating in Ontario may have provincial extra-provincial or other corporate administration duties.
T2 e-filing, adjustments and CRA enquiries
For tax years starting after 2023, most corporations must file T2 electronically unless a specified exception applies. The method may require CRA-certified corporate tax software or a qualified filer. Once filed, preserve the confirmation, assessment and all schedules. A CRA request for supporting documents is not always a full audit; respond to what is asked and keep transaction-level evidence.
If the filed T2 has an error, check the appropriate reassessment procedure and statute-of-limitations rules. Director changes and shareholder ownership dates can also affect who may communicate with the CRA or authorize representatives.
A realistic first-company year-end checklist
Close all bank and credit cards; list outstanding invoices and unpaid bills; validate payroll and HST control accounts; prepare a capital-asset register with disposal dates; reconcile shareholder loans and declared dividends; record inventory and prepaid expenses; determine legal year-end and applicable tax changes; prepare GIFI statements and tax schedules; calculate federal and provincial tax, instalments, carryforwards and payments; then save the T2 confirmation and CRA assessment.
Finally plan the next year's monthly closes and payroll compensation. Compare the legal/administrative costs with sole-proprietorship simplicity in our incorporation guide.
