Why you've received an invoice

When you file a tax return Inland Revenue passes your details on to us so we can invoice you for levies. This happens whether you're self-employed, a contractor, a shareholder-employee or you have staff.

    Why you have to pay levies

    Everyone in New Zealand who is in business, an employerself-employed or a contractor has to pay levies.

    Cover for you and your business

    The levies you pay are separate from general tax. They’re used to cover the cost of injuries caused by an accident and to help protect your most important asset – you and your people.

    You're covered by us as soon as you start your business or start working for yourself. The cover we provide helps with payment towards medical bills, treatment, help at home and work, and loss of income.

    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. 

    Assigning a classification unit

    When we get your details from Inland Revenue we assign you a classification unit (CU) based on your BIC code. This is connected to the levy rate you pay.

    You can check your BIC code on the BIC website.

    If your business details are wrong

    We get your income details from Inland Revenue. If they don’t look right on your invoice, you’ll need to get in touch with them to get this sorted. They’ll then send any updates on to us.

    Let us know if any other details on your invoice are wrong, as this could affect the levies you're paying. You can update your contact or business details online, and tell us if your business is no longer operating.

    When you’ll get an invoice

    The timeframe 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.
