If your Canadian business tops up a worker’s Employment Insurance (EI) during maternity or parental leave, the arrangement must meet strict federal guidelines. While these top-ups do not require registration with Service Canada, if the CRA audits your payroll and finds the plan exceeds limit thresholds or reduces other benefits, both the employer and employee could face severe tax penalties and EI clawbacks.
Offering maternity and parental leave top-ups is a fantastic way for companies in Toronto, Vancouver, and Montreal to attract and retain top talent. When an employee takes leave, Service Canada generally pays them Employment Insurance (EI) up to 55% of their average weekly earnings. Many generous employers step in to “top up” the remaining salary so the employee does not suffer financial hardship. However, if these payments are not structured correctly, the Canada Revenue Agency (CRA) will audit the business.
Under Canadian tax law, employer top-ups to maternity, parental, compassionate care, or family caregiver benefits do not need to be registered with Service Canada. 📋 However, the payments must meet specific federal criteria to avoid being treated as regular “insurable earnings.” If these requirements are not met-for instance, if the top-up reduces other benefits or is calculated improperly-Service Canada may claw back the employee’s EI, and the CRA could penalize the employer for failing to deduct the proper payroll taxes.
Step-by-Step Defence Process in a Payroll Audit
If a CRA payroll auditor targets your maternity leave top-up program, your accounting and HR teams must act immediately to prove compliance. Here is the standard process for handling the audit.
Step 1: Identifying the Audit Trigger
Audits usually begin when the CRA’s Trust Accounts Examination division notices discrepancies on your T4 summaries. If they see an employee received a T4E (from EI) and a regular T4 showing significant employment income during the exact same months, red flags are raised. The auditor will send a formal letter demanding an explanation of your top-up policies.
Step 2: Reviewing the Top-Up Plan Documentation
Your strongest defence is proving you have a valid, compliant top-up policy. While you are not required to register maternity or parental top-up plans with Service Canada, you must have clear internal records showing when the plan took effect. 📄 Your internal documentation must explicitly state that the top-up payments are designed solely to supplement EI benefits for pregnancy, caring for a newborn, or adoption, and do not reduce other accumulated employment benefits like vacation days or sick leave.
Step 3: Proving Top-Up Limits (The 100% Rule)
Even though registration is not required, the math must be perfect. Under federal rules, the combined weekly amount of the employee’s EI benefits and your corporate top-up cannot exceed 100% of their normal weekly earnings. (Note that the 95% limit applies strictly to registered SUB plans for temporary layoffs, illness, or training). If your payroll software mistakenly pays more than 100% of their regular salary, the entire top-up is considered regular earnings and becomes subject to EI premium deductions.
Step 4: Responding to the CRA Payroll Auditor
Once you gather your internal top-up plan records and the payroll ledgers proving the 100% threshold was respected, your CPA or tax lawyer will draft a formal response to the CRA. 💼 It is critical to communicate clearly that the payments were compliant maternity or parental top-up benefits, not regular wages, holiday pay, or accumulated sick leave, which have entirely different tax treatments.
Step 5: Filing a Notice of Objection
If the auditor rules against you and issues a massive reassessment for unremitted EI and CPP premiums on the grounds that your top-ups did not meet the conditions (such as exceeding 100% of normal earnings), you have 90 days to file a Notice of Objection. Your lawyer can represent your business, arguing the legal merits of the payment structure and, if necessary, seeking relief from penalties and interest under the Taxpayer Relief Provisions.
How Much Does an Audit Assessment Cost?
A failed payroll audit affects both the company and the vulnerable employee on leave.
- EI Clawbacks (Employee): Service Canada may demand the employee repay thousands of dollars in EI benefits because the unregistered top-up is considered active income.
- CRA Employer Penalties: The CRA will reassess the employer for failing to withhold CPP and EI on the top-up. The penalty is typically 10% to 20% of the missing premiums, plus compounding interest.
- Professional Fees: Hiring a tax law firm to dispute a complex payroll audit and file objections generally costs between $3,000 and $8,000 CAD.
How Long Does the Process Take?
Handling a payroll dispute is a lengthy process. The initial CRA audit will usually take 3 to 6 months to conclude. If you are hit with a reassessment, filing a Notice of Objection with the CRA Appeals Division typically adds another 12 to 18 months. Establishing a compliant internal top-up policy can be done immediately by your HR team, provided you have clear records indicating the effective date and terms of the plan before your employee’s leave begins.
Frequently Asked Questions (FAQ)
Do I have to register my maternity top-up plan?
No. Employers are not required to register plans used to supplement EI maternity, parental, compassionate care, or family caregiver benefits with Service Canada. However, you must keep internal records showing the effective date of your plan and demonstrating that it meets the required federal conditions.
Are top-up payments subject to income tax?
Yes. While an approved SUB plan exempts the top-up payments from EI premiums (and sometimes CPP contributions, depending on how it is structured), the payments are still considered taxable income. The employer must deduct standard income tax at the source.
What happens if an employee quits after maternity leave?
Many SUB plans include a “return to work” clause requiring the employee to stay with the company for a certain period (e.g., 6 months) after their leave. If they quit early, the employer can demand repayment of the top-up as a civil debt, but this does not retroactively change the tax treatment of the original SUB plan.
Can we pay 100% of the employee’s salary?
Yes! Under federal guidelines, the combined amount of the EI weekly benefits and the employer’s top-up can equal up to 100% of the employee’s normal weekly wage. However, if the combined total exceeds 100%, the top-up payments will be treated as regular earnings and subject to EI premium deductions.
