How to Prepare for CRA T4/T4A Filing Deadlines
As the filing season approaches, businesses across Canada are gearing up to meet the Canada Revenue Agency (CRA) deadlines for submitting T4 and T4A slips.
Whether you're a small business owner or a seasoned payroll professional, preparing for these deadlines is essential for compliance, avoiding penalties, and keeping your team happy. Let’s dive into why this topic is so important and explore actionable steps to get you ready.
Why Preparing for CRA T4/T4A Filing Deadlines is Important

1. Compliance with Legal Obligations
Filing T4 and T4A slips is a legal requirement for Canadian employers. These documents report employment income, deductions, and other payments made to employees and contractors. Missing the deadline can lead to penalties and scrutiny from the CRA.
2. Avoiding Penalties
The CRA imposes fines for late filing or inaccurate reporting. These penalties can add up quickly and create unnecessary financial strain on your business.
3. Building Employee and Contractor Trust
Timely and accurate reporting ensures employees and contractors can file their taxes without delays. This builds trust and maintains a good working relationship.
4. Streamlining Year-End Processes
Preparing ahead of time makes your year-end tasks less stressful and reduces the risk of errors. It’s also an excellent opportunity to review your payroll and bookkeeping systems.
5.Maintaining Professionalism and Reputation
Filing on time demonstrates your professionalism and organizational skills. It sends a positive message to employees, contractors, and the CRA.
Actionable Steps to Prepare for CRA T4/T4A Filing Deadlines

1. Understand the Deadlines
The deadline for submitting T4 and T4A slips to the CRA is typically February 28 of the following year. Employees and contractors must also receive their copies by this date. Mark it on your calendar and set reminders well in advance.
2. Gather All Necessary Information
To prepare T4 and T4A slips, you'll need:
- Employee and contractor details (names, addresses, SINs).
- Total earnings, deductions, and benefits for the year.
- Any additional information specific to T4A, such as fees, commissions, or payments for services.
- Ensure this data is accurate and up-to-date.
3. Verify Payroll Records
Double-check your payroll records for any discrepancies. Look for:
- Missing hours or incorrect salary amounts.
- Unreported bonuses, allowances, or benefits.
- Accurate CPP, EI, and income tax deductions.
- A payroll audit before filing can save you time and trouble.
4. Use CRA-Approved Software
Filing T4 and T4A slips online through the CRA’s “Internet File Transfer” or “Web Forms” is efficient and straightforward. Most payroll or accounting software is designed to handle these tasks, ensuring compliance and minimizing errors.
5. Reconcile with the CRA’s Records
Before filing, reconcile your payroll records with your CRA remittance history. Ensure all amounts for CPP, EI, and income tax deductions match what you’ve reported throughout the year.
6. Educate Yourself About Taxable Benefits
Certain employee benefits, such as health plans, car allowances, or gifts, may be taxable and need to be included on T4 or T4A slips. Review CRA guidelines to avoid missing taxable benefits.
7. Submit Electronically
The CRA encourages electronic filing, especially for businesses with more than 50 employees. Filing electronically reduces processing times and ensures accuracy.
8. Distribute Slips Promptly
Employees and contractors rely on T4 and T4A slips to file their taxes. Make sure they receive their copies by February 28. Consider sending these slips digitally to streamline the process.
9. Stay Updated on CRA Changes
Tax laws and reporting requirements change over time. Subscribe to CRA updates or consult your accountant to stay informed about any new regulations that may impact your filings.
10. Seek Professional Help if Needed
If you're unsure about any aspect of T4/T4A filing, consult a bookkeeper or accountant. They can provide expert guidance and ensure everything is done correctly.
Practical Tips to Make Filing Easier

- Keep Organized Records All Year
Regularly updating your payroll records ensures you’re not scrambling at year-end. Consistent record-keeping saves time and reduces stress.
- Automate Where Possible
Use payroll software that automatically calculates deductions, tracks benefits, and generates T4/T4A slips. Automation reduces the risk of human error.
- Create a Filing Checklist
A checklist can help you track your progress and ensure you don’t miss any steps in the filing process.
- Communicate with Employees and Contractors
Inform your team about when they’ll receive their slips and whom to contact if they spot errors.
What Happens if You Miss the Deadline?
Missing the filing deadline can result in:
- Late Filing Penalties: Starting at $100 and increasing based on the number of slips and how late they are.
- Interest Charges: On any unpaid amounts owed to the CRA.
- Audit Risks: Late or inaccurate filing may increase the likelihood of a CRA audit.
If you realize you might miss the deadline, contact the CRA immediately to discuss your situation and explore options.
