    Update your business details

    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 view your invoice and update your details in MyACC for Business.

    To access your MyACC for Business profile you’ll need:

    • a Google, Microsoft or RealMe account.

    To register each business you’ll need:

    • the ACC number or Inland Revenue number
    • an email address or New Zealand mobile phone number.

    Send us a form with your updated business details

    If you're an employer you can also complete the form below and email it through to us.

    Changes to your business we need to know about

    Changing your business activity

    If your business activity changes, e.g the products or services you offer, you may need to update your Classification Unit (CU). We assign each CU a levy rate, so a new CU could affect how much you pay in levies. In MyACC for Business you can check if your CU is correct.

    Check your current CU

    You'll also need to enter your new Business Industry Description (BIC) code when you file your next tax return with Inland Revenue. You can search for this on the BIC website:

    Working part-time or full-time if you’re self-employed

    If you’re self-employed, and earning under the full-time minimum, how many hours you work affects how much you pay in levies and the entitlements you get. This includes the hours you work across all sources of income. Make sure we know if you’re working:

    • part-time (an average of 30 hours or less a week over a tax year)
    • full-time (more than 30 hours a week on average over a tax year).

    Changing your payroll or shareholder remuneration

    You need to update any changes to your payroll or shareholder remuneration through Inland Revenue. They'll pass these details on to us and it will be updated automatically. Make sure you pay your current invoice. We'll get in touch with you about adjustments to your levies once we get the new information.

    Changing from self-employed to an employer

    If you’re hiring staff or changing from self-employed to an employer, get in touch. We’ll let you know if you need to close your self-employment account and help you register with us as an employer.

    Buying or merging a business

    If you’re buying a business, you’ll be taking on their claims history, including their experience rating. Your CU may also change. Make sure you contact us to talk about these changes.

    Receiving superannuation

    If you start receiving New Zealand Superannuation this may affect your weekly compensation. Contact us to talk about these changes.

    If you’re no longer in business

    If you’re no longer self-employed, working as a contractor or you’re closing your business, let us know using our online forms.
