Running a business means juggling countless responsibilities, deadlines, and obligations. Sometimes, despite your best intentions, important deadlines slip through the cracks—including your corporate tax filing.

If you’ve missed the deadline for submitting your T2 Corporate Income Tax Return to the Canada Revenue Agency (CRA), you’re likely wondering: “What happens now?”

This post outlines the immediate consequences of failing to file corporate taxes, the broader impact on your business operations, and most importantly, the specific steps you need to take to address the situation effectively.

The Immediate Financial Hit: Penalties and Interest

When your corporation misses its tax filing deadline, the financial consequences begin immediately and compound over time.

CRA Corporate Tax late Payment Penalty

The CRA imposes significant penalties for late T2 returns:

  • Initial penalty: 5% of the unpaid tax for the year
  • Monthly accumulation: An additional 1% of unpaid tax for each complete month your return is late (up to a maximum of 12 months)


For perspective, a small business with $20,000 in unpaid taxes filing just three months late would face:

  • Base penalty: $20,000 × 5% = $1,000
  • Monthly addition: $20,000 × 1% × 3 months = $600
  • Total penalty: $1,600


That’s $1,600 in completely avoidable expenses directly impacting your profit margin.

If you’ve been late filing in previous years or have received a formal demand to file from the CRA, these penalties double—to 10% of unpaid tax plus 2% for each late month—making the financial impact even more severe.

The Silent Drain: Daily Compounding Interest

Beyond penalties, interest begins accruing on any unpaid tax balance from the day your payment was due (typically two or three months after your fiscal year-end). The CRA compounds this interest daily at rates typically exceeding 10% annually.

Unlike most business expenses, CRA interest charges aren’t tax-deductible, making them particularly costly to your business. Every day that passes without filing and paying increases this financial burden.

Beyond Financial Penalties: The Broader Business Impact

Missing your corporate tax filing deadline affects more than just your immediate tax bill.

Cash Flow Constraints: Delayed Refunds and Credits

If your corporation is expecting a tax refund, filing late will delay its receipt. This can impact your cash flow planning and working capital availability, potentially forcing your business to delay investments or seek costly short-term financing to cover operational expenses.

Similarly, certain business tax credits might be jeopardized by late filing, potentially costing your business valuable deductions that could have reduced your overall tax burden.

Increased Scrutiny: Becoming an Audit Target

Late filing raises red flags with the CRA and can increase your corporation’s likelihood of being selected for a detailed review or audit.

Beyond the potential for additional assessments, audits consume significant time and resources, diverting your attention from core business activities.

Business Reputation and Financing Challenges

Financial institutions and potential investors often request copies of filed tax returns when evaluating your business for loans or investment opportunities. Late filings can:

  • Signal potential financial management issues
  • Result in less favorable loan terms
  • Delay crucial funding for business growth
  • Create challenges in business valuation during investment rounds


In some cases, persistent non-compliance can even result in the CRA taking legal action against your corporation or its directors, creating serious reputational damage that can be difficult to overcome.

Taking Immediate Action: Your Next Steps

When faced with a late corporate tax filing, swift and decisive action is essential to minimize the impact on your business.

1. File Your Return Immediately

Your absolute first priority should be completing and submitting your T2 return as soon as possible. Every additional day of delay increases your penalties and interest. Even if you can’t pay the full amount owing, filing the return stops the late-filing penalties from growing further.

2. Calculate Your Tax Liability

Once your return is filed, determine the total amount owing, including:

  • The base tax amount
  • Applicable penalties
  • Accrued interest


Understanding the full extent of your liability is essential for developing an effective payment strategy.

3. Make Payment Arrangements

If you can pay the full amount immediately, doing so will prevent further interest accumulation. The CRA offers multiple payment methods:

  • Online banking
  • Electronic funds transfer
  • Credit card (through third-party providers)
  • MyPayment service for debit cards


If full payment isn’t feasible, contact the CRA to discuss potential payment arrangements that allow you to satisfy your tax obligations over time.

Be prepared to demonstrate your corporation’s financial situation and propose a realistic payment schedule.

4. Explore Relief Options

In certain circumstances, the CRA may consider waiving or canceling penalties and interest through the Taxpayer Relief Program. Valid reasons may include:

  • Extraordinary circumstances beyond your control (natural disasters, serious illness)
  • CRA errors or delays
  • Serious financial hardship


To request relief, submit Form RC4288 with comprehensive documentation supporting your case. Success largely depends on the strength of your evidence and your corporation’s overall compliance history.

5. Address Underlying Compliance Issues

Take this opportunity to identify and fix the root causes of your late filing:

  • Was it a one-time oversight?
  • A recurring compliance challenge?
  • A resource or systems issue?


Understanding the underlying problems will help prevent similar issues in the future.

Protecting Your Business Moving Forward

With your immediate tax situation addressed, implement measures to ensure timely compliance going forward:

Implement Robust Internal Processes

  • Create a corporate tax calendar with key dates and internal deadlines
  • Assign clear responsibility for tax filing deadlines to specific team members
  • Build in buffer time to gather information and address unexpected challenges
  • Set automated reminders at regular intervals before deadlines

Consider Professional Support

Many businesses find that working with qualified tax professionals:

  • Ensures timely and accurate filings
  • Provides access to specialized knowledge
  • Frees internal resources to focus on core business activities
  • Often saves money through proper tax planning and avoidance of penalties

Leverage Technology Solutions

Frequently Asked Questions About Filing Corporate Tax Return Late

Your T2 Corporate Income Tax Return is considered late if it’s filed after your filing deadline, which is typically six months after your fiscal year-end. For example, if your corporation’s year-end is December 31, your T2 return must be filed by June 30 of the following year to be considered on time.

These are two separate deadlines. The payment deadline is typically two months after your fiscal year-end for most corporations (three months for Canadian-controlled private corporations eligible for the small business deduction). The filing deadline is six months after your fiscal year-end. You can incur penalties for missing either deadline, even if you meet the other one.

The CRA may send reminder notices about your late filing, but don’t count on being notified. The penalties and interest start accruing automatically from the deadline dates, regardless of whether you receive any communication from the CRA. It’s your responsibility to know and meet your filing obligations.

Yes, you can use the CRA’s Corporation Internet Filing service for late returns, just as you would for on-time filings. E-filing is generally faster and provides immediate confirmation that your return has been received.

After processing your late return, the CRA will send a Notice of Assessment that details any penalties and interest charged. You can also check your corporation’s account through the CRA’s My Business Account online service or call the CRA’s business enquiries line for an update on your balance.
