Top Payroll Compliance Mistakes Canadian Employers Make

For most employees, payday just happens. But behind the scenes, payroll is one of the most demanding functions an HR or finance team manages. The deadlines are fixed, the rules are detailed, and the margin for error is slim.


In Canada, that complexity is layered. Federal and provincial regulations don't always align, and they change more often than most people realize. On top of that, payroll teams are responsible for far more than processing wages. We're talking benefit deductions, overtime, vacation tracking, garnishments, Records of Employment, new hire onboarding, terminations, and year-end tax filings, to name a few.


Make a mistake, and you're not just dealing with an unhappy employee or problem to correct. You could be looking at a compliance issue that could penalize your business and take months to correct.


In this blog, we’ll answer common questions about top compliance mistakes, penalties and how often you should review payroll processes. 


Here is what we’ll cover:

  • What are the most common payroll compliance mistakes Canadian employers make?
  • What penalties can Canadian employers face for payroll compliance errors?
  • How can employers avoid CRA payroll penalties?
  • How often should Canadian employers review payroll compliance processes?


What are the most common payroll compliance mistakes Canadian employers make?


Payroll compliance issues happen, often by mistake. There are many rules, regulations, and ever-changing laws. It's a lot to manage when you're also running a business or supporting a busy HR function. Here are the most common payroll errors we see as HR consultants, along with what you can do about them.


1. Missing Federal & Provincial Deposit Deadlines


Missing deadlines is an easy way to rack up interest payments and potential fines. Your remittance deposit schedule is based on your estimated annual gross payroll and what you remitted the prior year. Confirm your schedule at the start of each year and build it into your payroll calendar.


Penalties for late remittances compound with each repeat offence. A simple reminder system or automated payment schedule can save you a significant headache.


2. Misclassifying Employees vs. Independent Contractors


The CRA looks at the actual working relationship, not just what's written in a contract. They consider factors like control over work, who owns the tools, and whether there's a real chance of profit or loss.


If a contractor is later reclassified as an employee, you could be on the hook for back CPP contributions, EI premiums, income tax withholdings, plus penalties and interest. When there's any doubt, document your reasoning and compare it against CRA's published guidelines.

3. Incorrect Statutory Deductions and Remittances


CPP contributions, EI premiums, and income tax withholdings need to be calculated correctly every pay cycle. Rates and thresholds change annually, and a small miscalculation across a full workforce adds up fast.


Build a year-start review into your payroll process to make sure your system reflects the latest numbers before the first payroll of the year runs. Repeated errors or underpayments increase your audit risk.


4. Missing or Incorrect Record of Employment (ROE) Filings


An ROE is required any time an employee has an interruption in earnings, and the timeline for issuing one is tight. Delays or errors can directly affect an employee's access to EI benefits.


Make sure your payroll team knows when an ROE is triggered and has a clear process for issuing them accurately and on time.


5. Non-Compliance with Provincial Employment Standards


Tax rules are federal, but overtime, vacation pay, statutory holidays, and termination pay are governed provincially, and the rules vary more than most people expect.


Mistakes happen most often when businesses expand into a new province and assume their existing practices still apply. Review the employment standards legislation for every province where you have employees and make sure your payroll reflects those differences.

6. Improper Handling of Termination Pay and Severance


A common mistake is treating statutory minimums as the full extent of your obligation. Entitlements can be significantly higher depending on the employee's tenure and role.


Miscalculating termination pay, forgetting accrued vacation, or issuing final pay outside the required window can all lead to complaints or wrongful dismissal claims. Get the numbers right and document everything.

7. Failure to Track Taxable Benefits Correctly


Employer-provided benefits like company vehicles, housing allowances, bonuses, and gift cards need to be reported properly on T4 slips. Missing or underreporting these can trigger reassessments and penalties.


Do a mid-year review of any non-cash compensation you're providing and check it against current CRA guidance on taxable benefits.


8. Inadequate Record-Keeping


Canadian employers are legally required to keep detailed payroll records. This includes hours worked, wage rates, overtime, vacation accrual, and deductions.


When an audit happens or an employee files a complaint, your records are your first line of defence. If your record-keeping has gaps, fix that before a problem surfaces.

What penalties can Canadian employers face for payroll compliance errors?


The CRA takes payroll compliance seriously, and the penalties for getting it wrong escalate quickly. Most of these penalties are avoidable with the right processes in place, but if issues go unaddressed, the costs add up fast. Here is a summary of the penalties you could face for payroll compliance errors:


1. Late or Missing Remittance Penalties

  • 10% penalty for failure to remit source deductions on time
  • 20% for second or subsequent failures made knowingly or under gross negligence
  • Daily compound interest on unpaid balances, including on any unpaid penalties


2. Failure to Deduct CPP, EI, or Income Tax Penalties

  • 10% penalty on amounts that were not properly deducted
  • 20% if the failure was intentional or due to gross negligence
  • The penalty generally applies to amounts over $500 — but if the failure was deliberate, it applies to the full amount


3. General Non-Compliance Penalties 

  • Fines ranging from $1,000 to $25,000
  • In serious cases, imprisonment of up to 12 months is possible under the Income Tax Act



4. Employee Misclassification Penalties

  • Retroactive CPP contributions, EI premiums, and income tax withholdings for the full period of misclassification
  • Penalties and daily compound interest applied to all amounts owed


How can employers avoid CRA payroll penalties?

Most CRA penalties are preventable. You can avoid payroll penalties by taking these steps:


Automate remittances: Set up recurring payments so deadlines are never missed

Use payroll software: Automate CPP, EI, and tax deductions to reduce calculation errors

Know your deadlines: Remit based on your assigned schedule 

Keep detailed records: Maintain payroll records, including earnings and deductions, for a minimum of six years

Get professional support: Regular audits by a payroll or HR professional help catch issues before the CRA does. AugmentHR can assist with this. 


How often should Canadian employers review payroll compliance processes?


At a minimum, Canadian employers should review payroll compliance annually. If you want to stay ahead of tax changes, regulatory updates, and potential errors, quarterly reviews are a smarter standard. Payroll isn't a set-it-and-forget-it function. Employee status changes, updated tax rates, and new legislation can all create compliance gaps if they're not caught early.


The goal isn't to create more administrative work. It's to make sure small issues get caught before they become expensive ones.
