Workers’ Compensation Payroll Inclusions and Exclusions
On this page
Premium payroll is not automatically the same as accounting payroll. Start with gross remuneration, then document each inclusion, exclusion, cap, minimum, allocation and exemption under the applicable policy or scheme.
Create a gross-to-insurable payroll bridge
For each class and period, show gross payroll plus included non-cash or contract amounts, less allowed exclusions and earnings above applicable caps. Tie the result to payroll journals and the reported exposure.
Identify ordinary included earnings
Wages, salaries, bonuses, commissions, vacation pay, sick pay and other remuneration can be included, but the exact list differs. Ontario WSIB and WorkSafe Victoria publish detailed inclusions for their schemes.
Do not guess overtime treatment
Some rules allow exclusion of the overtime premium portion when records separate it; others include overtime differently. Retain straight-time and premium components and cite the governing rule.
Officers, owners and partners need separate evidence
Coverage elections, exemptions, reduced rates, payroll minimums and maximums can apply. Record entity type, role, jurisdiction, election status and the amount used rather than mixing them into ordinary employee payroll.
Apply per-worker caps at the correct level
A maximum assessable earnings amount usually applies per worker, not as a blanket reduction from total payroll. Keep employee-level detail so caps can be reproduced.
Allocate common earnings only under the written method
Ontario WSIB describes proportional allocation of common earnings across multiple activities. Other jurisdictions can use a predominant or governing classification. Use the correct local method.
Enter the reconciled amount, not raw gross payroll
After the bridge is supported, enter the class-level insurable amount in the Workers’ Compensation Premium & Audit Calculator. Preserve the worksheet for review.
Frequently asked questions
Is gross payroll always the workers’ compensation payroll base?
It is often the starting point, but inclusions, exclusions, caps and special rules can change the rateable amount.
Can I subtract owner pay automatically?
No. Owner, officer and partner treatment depends on entity, election, jurisdiction and scheme rules.
