Employee Information

This is the foundation of your payroll system. You must keep accurate personal and employment details for every employee, including full name, Social Insurance Number (SIN), address, job title, and start date. This information is used by the CRA to verify identity, calculate deductions properly, and ensure each employee is correctly registered in your payroll system. Any errors here can affect tax reporting and lead to compliance issues.

Earnings Records

Earnings records track how much you pay each employee. This includes regular wages, overtime, bonuses, commissions, and any other compensation. These records are essential because all payroll deductions are calculated based on gross earnings. If your earnings data is incomplete or inaccurate, your tax calculations will also be wrong, which can lead to underpayment or overpayment of taxes.

Deductions

You are required to document all payroll deductions, including Canada Pension Plan (CPP), Employment Insurance (EI), and income tax. Each deduction must be calculated correctly and recorded clearly for every pay period. These records prove that you are withholding the correct amounts and remitting them to the CRA. Incorrect deductions are one of the most common compliance mistakes and can result in penalties.

Timesheets and Hours Worked

Tracking employee work hours is critical, especially for hourly employees. You should maintain detailed timesheets showing hours worked, overtime, vacation time, and any unpaid leave. These records justify how wages were calculated and are particularly important if there are disputes or audits. Without accurate time tracking, you cannot prove that employees were paid correctly.

Payroll Remittance Records

These records show when and how much you have sent to the CRA. Every remittance must be documented with the exact amount, date, and method of payment. This helps confirm that you are meeting your remittance obligations on time. If the CRA questions your payments, these records are your proof that everything was submitted correctly.

T4 Slips and Summaries

T4 slips report each employee’s annual earnings and deductions. You must prepare and issue these at the end of each tax year, along with a T4 summary for the CRA. Keeping copies ensures you have a record of what was reported. Errors in T4s can trigger audits or require corrections, so maintaining accurate records is essential.

Employment Contracts

Employment agreements outline the terms of each employee’s compensation, benefits, and responsibilities. These documents support your payroll structure and help explain why employees are paid a certain way. They are also important for verifying classification, especially in cases where the CRA may question whether someone is an employee or contractor.

Key Takeaway

Each of these records plays a direct role in maintaining payroll tax compliance. Together, they create a complete financial trail that protects your business during CRA reviews, helps prevent errors, and ensures your payroll system runs smoothly. Keeping them organized and up to date is not optional, it is a core requirement for every employer in Canada.

Payroll Filing and Remittance Deadlines in Canada 

Meeting deadlines is one of the most critical parts of CRA payroll requirements. Late payments or filings are one of the main reasons businesses get penalized.

Your remittance schedule depends on your business size: 

In addition to remittances: 

• T4 slips must be filed by the end of February each year
• You must also provide copies to employees by the same deadline

Missing deadlines can trigger penalties immediately, even if the amount is small.

Common Payroll Compliance Mistakes and Penalties

Many businesses fail payroll tax compliance not because they ignore rules, but because they misunderstand them. Here are the most common issues:

• Incorrect deductions
  Not calculating CPP, EI, or income tax correctly
• Late remittances
  Sending payroll taxes after the deadline
• Misclassifying workers
  Treating employees as contractors incorrectly
• Incomplete records
  Missing documentation during a CRA review
• Failure to file T4s on time
  Delays in year-end reporting
