What You’ll Learn Here

Employment Insurance premiums aren’t complicated once you understand the basic structure. We’re breaking down the calculation process into manageable steps — no accounting degree required. Whether you’re running payroll for 5 employees or 50, you’ll find practical guidance that applies to your situation.

The key is understanding that EI rates change by province and update annually. Missing a remittance deadline? That costs real money in penalties. This guide helps you stay on top of both.

                    Remittances due within 15 days of month-end

How EI Premium Calculations Work

The calculation is straightforward — multiply the employee’s insurable earnings by the applicable premium rate for your province. But here’s where people get tripped up: you can’t just use one national rate.

In 2026, Ontario employers deduct 1.63% from employee paycheques, while BC employers deduct 1.58%. Your province determines your rate. You also contribute an employer premium, which is slightly higher — typically 2.28% in Ontario for example. The employee pays once, you pay a matching amount (or slightly more).

Example Calculation

Let’s say Sarah earns $4,500 monthly in Ontario. Her EI deduction: $4,500 1.63% = $73.35 per month. Your employer contribution: $4,500 2.28% = $102.60. Total EI cost to process Sarah’s pay: $175.95.

Provincial Rate Variations

Here’s the reality: location matters. The lowest employee rate in 2026 is BC at 1.58%, while some provinces run closer to 1.66%. That’s an 8-basis-point difference, which doesn’t sound like much until you’re calculating it across your entire payroll.

What makes this tricky is that rates change annually — usually announced in September for the following year. You need to update your payroll software before January 1st rolls around. Missing this update means you’re either over-deducting from employees or under-remitting to CRA.

The best practice? Set a calendar reminder in early September to check Service Canada for the updated rates. It’s a 5-minute job that prevents months of headaches.

Remittance Deadlines and Schedules

This is where employers actually get penalized. The remittance deadline isn’t flexible — it’s 15 days after the end of the month. Miss it, and you’re paying interest at the prescribed rate (currently around 9% annually) plus potential penalties.

Most payroll professionals work backward from this deadline. If your month ends on January 31st, your remittance is due by February 15th. You’re remitting both the employee deductions you’ve held plus your employer contribution. One cheque, one deadline.

Penalties and How to Avoid Them

Late remittance penalties aren’t a warning — they’re real costs that impact your bottom line. CRA charges interest on late payments at the prescribed rate, which compounds monthly. A $5,000 late remittance can cost you an extra $50-100 in interest charges alone, depending on how late you are.

There’s also a failure-to-remit penalty: 10% of the amount not remitted on time, plus the interest. So that $5,000 becomes $5,500 plus interest. It adds up quickly.

“The smartest businesses treat EI remittances like tax payments — they set money aside immediately and process them before the deadline. One late remittance teaches this lesson faster than any compliance training.”

Practical Penalty Prevention

Automate Remittances

Set up automatic payments through your bank 2-3 days before the deadline. No manual processing, no excuses.

Use Payroll Software

Modern payroll systems calculate EI automatically and flag remittance dates. They’re worth the investment.

Track in Spreadsheets

If you’re using manual processes, create a simple tracker showing what’s owed and when it’s due.

Separate Bank Account

Some businesses hold deductions in a separate account to prevent accidentally spending funds earmarked for CRA.

Key Takeaways

EI premiums aren’t complex once you understand the structure. Calculate based on provincial rates, track your monthly obligations, and remit by the 15th of the following month. That’s it.

The real cost of getting this wrong isn’t in the calculation itself — it’s in the penalties and interest you’ll pay. A few minutes each month to verify your rates and set remittance reminders saves thousands annually. You’ve got this.
