Payroll Penalties and Interest

Employers have a variety of obligations under The Workers Compensation Act. To ensure the compensation system works smoothly and efficiently it’s important that employers fulfill these obligations. To respond to cases where an employer fails to comply with their responsibilities, the Act includes provisions for both fines and penalties. The Administrative Penalty Regulation (71/2021) sets out the penalty levels. The Interest and Financial Matters Regulation (123/2021) sets out the interest rates that the WCB may charge or pay on accounts.
