Understanding BIC and CU Codes for ACC Levies
In New Zealand, your business's primary activity is classified using a Business Industry Classification (BIC) code. This classification is crucial as it determines the ACC (Accident Compensation Corporation) levy you'll pay. Each BIC code is associated with a specific five-digit Classification Unit (CU) code, which groups industries with similar risk profiles for levy calculation.
