WorkSafeBC Premiums

Definition

WorkSafeBC premiums (formally, assessments) are the amounts an employer pays to WorkSafeBC to fund the Workers' Compensation no-fault insurance system. Premiums are calculated by multiplying the employer's assessable payroll by a rate assigned to the employer's classification unit (CU). The system is no-fault, fully funded, and adjusted annually through the WorkSafeBC rate review process.

Key rules

• Assessable earnings are the employee's gross earnings up to an annual maximum. The 2025 maximum assessable earnings is $116,700 per worker; this is adjusted annually and published in the WorkSafeBC rate list.
• The base premium rate is set per classification unit. For 2025, the BC average base rate was approximately $1.55 per $100 of assessable payroll. Rates vary widely by industry risk: office-based consulting classifications typically fall between $0.14 and $0.50, while construction, logging, and resource extraction can exceed $5.00.
• The final rate applied to a given employer is the CU base rate adjusted for Experience Rating. Employers with better-than-average injury experience receive a discount; worse-than-average experience results in a surcharge. Single-person corporations with no claims typically receive a small discount over time.
• Quarterly returns are due April 20 (for Q1), July 20 (Q2), October 20 (Q3), and January 20 (Q4 and year-end reconciliation). Very small employers may be placed on annual reporting.
• An annual Employer Payroll and Contract Labour Report is used to reconcile estimated payroll to actual payroll, with true-up adjustments assessed or refunded on the next statement.

Example

A one-person BC consulting corporation is classified under CU 766014 (Business Services) with a 2026 base rate assumed at $0.20 per $100 and no experience adjustment in year one. The shareholder-employee is paid a $100,000 annual salary, below the maximum assessable earnings.

• Quarterly assessable payroll: $25,000.
• Quarterly premium: $25,000 × $0.20 / $100 = $50.
• Annual premium: approximately $200.

If the same corporation adds a second worker paid $60,000 annually:

• Combined annual assessable payroll: $160,000 (both below the individual maximum).
• Annual premium: $160,000 × $0.20 / $100 = $320.

At year-end, the corporation files the annual reconciliation. If actual payroll exceeds the estimate, a top-up assessment is issued; if lower, a credit or refund is applied.

Common mistakes

• Over-assessing by failing to cap at the maximum assessable earnings per worker. A shareholder paid $200,000 has only $116,700 (2025 figure) of assessable earnings for WorkSafeBC purposes.
• Missing a quarterly return. Even if no payroll was paid in the quarter, a nil return is required.
• Misclassification. Declaring a lower-rated CU than the operations warrant leads to reassessment plus interest and penalties during audit.
• Including non-assessable amounts (for example, dividends, severance paid after termination of all employment, or benefits excluded from the assessable earnings definition) in the base.
