Changes to your business we need to know about
Changing your business activity
If your business activity changes, eg 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.
Log in to 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, 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.
