CRA Filing Deadlines for Businesses: Avoid Penalties and Stay Compliant

There are many responsibilities involved in running a business in Canada; the one that is most important is keeping up with your CRA filing deadlines. When a deadline is missed, you may face penalties, interest, and attention from the Canada Revenue Agency (CRA).

The challenge? The CRA doesn’t always have the same business tax deadlines. Your deadlines will be based on your business structure, your fiscal year-end, and the type of return you are filing.

This guide explains each of the major CRA filing deadlines in business terms to ensure you always know what’s due, when it’s due, and what you can do if you’re late.

What Are CRA Filing Deadlines for Businesses?

CRA deadlines are the dates that Canadian businesses are required to file tax returns, remittances, and other financial statements with the Canada Revenue Agency. The CRA tax filing deadlines exist to make sure that taxes are paid in a timely manner and businesses remain in compliance with tax regulations in Canada.

Most entrepreneurs make the mistake of thinking that their filing deadline and payment deadline are not the same.

• Your filing deadline is when your return must be filed with the CRA.
• Your payment deadline is when any taxes owed must be paid.

In many instances, you have to pay your tax before filing a tax return. Missing either one can result in penalties and daily compound interest, so it’s critical to track both CRA filing due dates separately.

Which CRA Filing Deadlines Apply to Different Business Types?

Your business structure determines which deadlines apply to you. Here’s a quick overview:

Business Type	Filing Deadline	Payment Deadline
Sole Proprietor / Self-Employed	June 15	April 30
Corporation (General)	6 months after fiscal year-end	2 months after fiscal year-end
Canadian-Controlled Private Corporation (CCPC)	6 months after fiscal year-end	3 months after fiscal year-end

Important note for self-employed individuals: Even though you have until June 15 to file, payment of any balance due is due by April 30 without interest. In practice, treat April 30 as your real deadline.

For incorporated businesses, your deadlines shift based on when your fiscal year ends, which means your CRA business tax deadlines could fall at any point during the year, not just in spring.

When Is the Corporate Tax Return (T2) Deadline?

Every corporation in Canada, whether profitable or not, must submit an annual corporate income tax return (T2). This is a non-negotiable legal requirement.

The T2 corporate tax return deadline is six months after the end of your corporation’s financial year.

These are some typical examples:

Fiscal Year-End	T2 Filing Deadline	Payment Deadline (General Corp)	Payment Deadline (CCPC)
December 31	June 30	February 28	March 31
March 31	September 30	May 31	June 30
June 30	December 31	August 31	September 30
September 30	March 31	November 30	December 31

Notice that payment deadlines arrive well before the filing deadline. This catches many business owners off guard, especially in their first year of incorporation.

What about installments? If your corporation is in a position to pay over $3,000 in taxes for the year, you will need to make monthly or quarterly payments during the year. These are separate from your year-end payment and have their own due dates.

When Are GST/HST Returns Due?

You must register your business to pay the GST/HST (Goods and Services Tax and the Harmonized Sales Tax) when your annual revenue exceeds $30,000. The deadline for filing GST/HST is based on your reporting period:

Reporting Period	Who It Applies To	Filing & Payment Due
Annual	Businesses with under $1.5M in taxable sales	3 months after fiscal year-end
Quarterly	Businesses with $1.5M–$6M in taxable sales	1 month after each quarter-end
Monthly	Businesses with over $6M in taxable sales	1 month after each month-end

Here are a few things to know: 

• Businesses with annual taxable sales of more than $1.5M must submit GST/HST returns electronically.
• If you did not receive any GST/HST during a period, you may have to file a nil return.
• If you’re filing an annual return and your turnover increases substantially, the CRA may require you to switch to quarterly or monthly filing.

Remembering the GST/HST filing deadline is particularly crucial, as it is linked directly to cash flow, and penalties may quickly add up for high-volume businesses.

What Are the Payroll Remittance Deadlines?

If your business has employees, you must be responsible for deducting and remitting Canada Pension Plan (CPP) contributions, Employment Insurance (EI) premiums, and income tax on your employees’ behalf. These payroll remittance deadlines are determined by your remitter type, which is based on your average monthly withholding amount (AMWA).

Remitter Type	AMWA (2 Years Prior)	Remittance Due Date
Quarterly Remitter	Less than $3,000	15th of the month after each quarter
Regular Remitter	$25,000 or less	15th of the following month
Accelerated Threshold 1	$25,000–$99,999	Within 3 days after the 15th and last day of each month
Accelerated Threshold 2	$100,000 or more	Within 3 days of each payday

Beyond regular remittances, don’t forget:

• T4 and T4A slips must be filed with the CRA and distributed to employees by the last day of February each year.
• New employers typically start as regular remitters until the CRA reassigns a remitter type based on your withholding history.

Missing payroll remittance deadlines is one of the most penalized areas in CRA compliance; directors of corporations can even be held personally liable for unremitted payroll deductions.

What Happens If You Miss a CRA Filing Deadline?

Missing a CRA filing deadline isn’t just inconvenient; it’s expensive. Here’s what you can expect:

• Late Filing Penalty: CRA will charge 5% of the unpaid tax on the day your return is late, plus 1% for each month after your return is late up to 12 months.
• Repeat Failure Penalty: If you’ve received a late-filing penalty in each of the last three years and you file late again, the penalty is doubled for the late filing: 10% of unpaid taxes plus 2% per month up to 20 months.
• Daily Compound Interest: The CRA also charges daily compound interest on the unpaid balance beginning from the day after your payment was due.
• Audit Risk: If your business regularly misses deadlines for filing, your account could be flagged for a CRA audit, adding extra stress and administrative load on your business.
• Voluntary Disclosures Program (VDP): If you’ve missed a filing deadline, you may need to use the CRA’s Voluntary Disclosures Program to come forward, correct your filings, and avoid penalties, but only if the CRA hasn’t contacted you about the issue. Acting early is key.

How Can Businesses Avoid CRA Late-Filing Penalties?

The good news: CRA late filing penalties are entirely avoidable with a little planning. Here’s what works:

1. Set up CRA My Business Account: This free online platform allows you to see when your CRA filing is due, see account balances, and manage CRA returns all in one place. It’s the simplest approach to information.

2. Use Accounting Software: Software such as QuickBooks or FreshBooks can keep a record of deadlines, send reminders, and help you stay on top of GST/HST, payroll, and corporate tax obligations throughout the year.

3. Work with a CPA or bookkeeper: A qualified accountant tracks your deadlines for you, ensures accurate filings, and identifies tax-saving opportunities you might otherwise miss.

4. File Even If You Can’t Pay: If cash flow is tight, file your return on time anyway. Late filing penalties and late payment interest are charged separately. Filing on time eliminates the penalty even if the balance takes longer to pay.

5. Set Up Pre-Authorized Debit: For installment payments and remittances, pre-authorized debit through CRA My Business Account ensures payments go out on time automatically.
