Hiring Your First Employee: Payroll, Source Deductions, and WCB Registration
The moment you hire in PEI, you owe a CRA payroll account and, in almost every industry, mandatory WCB registration before your first day of operations, not your first payday.
1. Two Registrations, Two Different Deadlines
Hiring your first employee in PEI triggers two separate mandatory registrations with two different clocks running:
| Registration | Who requires it | Deadline |
|---|---|---|
| CRA Payroll (RP) program account | Canada Revenue Agency | Before your first remittance due date (the 15th of the month after you start withholding deductions) |
| WCB employer registration | Workers Compensation Board of PEI | Before the start of operations, not after your first payday |
2. Setting Up the CRA Payroll Account
If you already have a Business Number from registering your business, you simply add a payroll (RP) program account to it. If you don't, Business Registration Online through your CRA My Business Account is the fastest route to get both at once. Once registered, you're responsible for:
- Collecting a completed TD1 (federal and provincial) from every new employee
- Calculating and withholding income tax, CPP contributions, and EI premiums from every payment
- Remitting those deductions by your assigned due date
Missing the registration deadline doesn't excuse you from remitting on time — you still owe the deductions and can be penalized for late filing even without an account set up yet.
3. WCB Registration Is Not Optional in Most Industries
Any PEI employer with one or more workers must register with the Workers Compensation Board and renew every year by February 28, reporting actual payroll from the prior year and an estimate for the current year. A handful of industries are excluded under the Workers Compensation Act, but most aren't.
| Detail | 2026 figure |
|---|---|
| Maximum Assessable Earnings (MAE) per worker | $89,300 |
| Assessment basis | Per $100 of assessable payroll, by industry rate group |
| Renewal deadline | February 28 annually |
Failing to register before starting operations can result in an arbitrary assessment plus penalties, and you may have to personally reimburse WCB for the full cost of any claim filed before you were registered.
4. Avoiding an Underestimating Penalty
If your actual payroll ends up more than 25% higher than the estimate you filed, WCB applies an underestimating penalty. Two ways to avoid it:
- Revise your payroll estimate before November 1 if your hiring plans change mid-year.
- Join the Monthly Assessment Payment Option (MAPO), which bases your monthly premium on actual payroll rather than an annual estimate.
5. The Sequence in Practice
- Register your business and get a Business Number (if you haven't already).
- Add a CRA payroll program account before your first remittance is due.
- Register with WCB before your first day of operating with an employee, not after.
- Collect TD1 forms from each new hire before their first pay run.
