CU codes group businesses with similar levels of risk together to decide the levy rate you pay and share the cost of injuries fairly.

The amount of levies you pay each year depends on:
- your CU - what work you do and the industry you're in
- if you have employees - how much you pay them
- if you're self-employed or a contractor - how much you earn and if you work full-time or part-time
- the type of cover you're on
- your claims history.
How we get your business details
When you file a tax return or register for GST with Inland Revenue, you'll choose a Business Industry Classification (BIC) code. This describes the business activity you do, eg your BIC code for gas plumbing services would be 'E323120 Gas plumbing'.
Inland Revenue passes these details on to us, along with your liable income or payroll, and contact details so we can invoice you for levies.
Let us know if your details are incorrect:
Assigning your business a classification unit (CU)
We use your BIC code to assign you or your business a classification unit (CU). CUs group businesses with similar levels of risk together to decide the levy rate you pay and share the cost of injuries fairly.
We assign levy rates to CUs based on data from past claims. This information helps us predict how many claims we’ll get from each levy group and what they’ll cost.
For example, a professional athlete has a higher risk of injury at work than an office worker. This means we'll assign the professional athlete a different CU and they'll pay a higher work levy.
Our levy guidebook has the full list of CUs and their levy rates:
You can see what your current CU is on your MyACC for Business and check your BIC code on the BIC website.
Understanding your cover options
You're covered by us as soon as you start your business or start working for yourself. If you've just started out, you'll be on our standard cover. This cover will change as your business grows, you hire employees or if you choose one of our opt-in products such as CoverPlus Extra or the Accredited Employer Programme.
Your claims history and your levies
If your business has paid at least three Work levy invoices, we may add you to the Experience Rating programme. This adjusts your Work levy based on historical claims and health and safety performance.
Your levy can stay the same, be discounted or have a loading. You could reduce your Work levy by preventing injuries at work and helping your injured employees get back to work sooner.
When you’ll get a levy invoice
The time frame depends on the type of business you are:
- self-employed and contractors- after you file a tax return you'll receive an invoice from us based on your income filed with Inland Revenue
- employers and shareholder-employees- you’ll receive an invoice from us every year based on your liable payroll filed with Inland Revenue. This invoice includes both your final levy and a provisional levy
- if you’re a new business, your invoice will be triggered when you file your first tax return. This is usually in your second year of business.
