If you’ve recently incorporated a business in Canada, you might be wondering whether you can save money by filing your own corporate income tax return rather than hiring an accountant. The short answer is:

Yes, you can file your own corporate taxes but it’s rarely recommended.

Corporate tax filing (T2 return) is significantly more complex than personal tax filing and involves accounting standards, corporate reporting rules, and CRA compliance requirements that most owners are not familiar with.

This guide breaks down when you can file your own corporate taxes, when you shouldn’t, and why many Canadian business owners choose to work with a professional.

1. Yes, Legally, You Can File Your Own Corporate Taxes

There is no law requiring corporations to use an accountant.

If you are competent enough to:

• prepare financial statements
• record depreciation
• calculate retained earnings
• manage capital cost allowance
• handle expense categorization
• understand carryforward losses
• file tax schedules correctly

you are allowed to file a T2 return yourself.

But most business owners discover that it’s not the filing that’s difficult it’s making sure that the numbers behind the filing are correct.

2. Corporate Tax Filing Is More Complex Than Personal Tax Filing

Personal taxes involve:

• income
• expenses
• maybe some credits
• perhaps investments

Corporate taxes involve:

• T2 corporate tax filing
• GIFI financial statement mapping
• Notice-to-Reader or compiled financials
• Capital Cost Allowance (CCA) classes
• Shareholder loans
• GST/HST reconciliation
• Payroll reconciliation
• Corporation losses & carryforwards
• Scientific Research & Experimental Development (SR&ED) credits
• Dividend vs salary treatment for the owner
• Adjusting entries and accrual accounting
• Year-end closing journal entries

Unlike personal filing, corporate reporting must follow accounting standards, not just tax forms.

3. Risks When Filing Corporate Taxes Yourself

Many owners who DIY corporate taxes make errors such as:

• incorrectly claiming expenses
• misclassifying shareholder withdrawals
• failing to track CCA properly
• misunderstanding taxable vs non-deductible expenses
• incorrectly reporting revenue
• missing tax credits or deductions
• filing late and paying penalties
• incorrectly calculating retained earnings
• misreporting GST/HST
• incomplete books and records

These mistakes can trigger:

• CRA review
• CRA audit
• penalties & interest
• reassessments
• back-tax liabilities

Some mistakes are not fixable after filing without an adjustment process.

4. When It MAY Be Safe to File Yourself

It might be manageable to file your own corporate taxes if:

• Your corporation is inactive
• You have zero revenue
• You had no expenses
• You had no payroll
• You had no assets or depreciation
• You had a clean corporate structure
• You understand basic bookkeeping

For example:

If you incorporated but didn’t actually run the business yet, this is a simple return.

5. When You Should Use an Accountant

You should not file yourself if:

• You have revenue
• You have employees
• You claim expenses
• You pay GST/HST
• You purchased equipment or assets
• You pay yourself salary or dividend
• You have a shareholder loan
• You operate across provinces
• You have external investors or debt
• You plan to apply for financing

In these cases, the cost of professional support is far less than the cost of making mistakes.

6. Software vs Accountant

Many business owners try to use:

• TurboTax Business
• TaxTron
• FutureTax
• SimpleTax (not corporate)
• TaxCycle
• UFile Pro

While these tools allow filing, they do not:

• audit your numbers
• correct bookkeeping errors
• calculate depreciation correctly
• advise on deductions
• optimize tax strategy
• advise salary vs. dividend decisions
• prepare Notice-to-Reader financials
• deal with a CRA review

Software only enters data, an accountant ensures the data is correct.

7. Filing Your Own Corporate Taxes Doesn’t Save Money, It Often Costs More

Most business owners try to do their own corporate taxes to “save money.”

But what often happens is:

• They overpay taxes by missing deductions
• They trigger a CRA review due to improper reporting
• Their books are incorrect and require professional cleanup
• Their filings need amendments later
• Their shareholder loan gets misclassified
• Their CCA is not optimized

A good accountant usually saves more money in taxes than they cost in fees.

Conclusion

But unless your corporation has:

it is usually safer and more financially beneficial to rely on an accountant.

Corporate taxes are not just a filing exercise they are a reflection of your entire financial year. Filing them incorrectly can lead to costly consequences.
