What you need to calculate your levies

Before you can calculate your levies you need to know your:

• type of cover
• Business Industry Classification Code(BIC) or Classification Unit (CU)
• liable income(if you’re self-employed or a shareholder-employee)
• liable payroll (if you’re an employer)
• employment status – full-time or part-time work (if you’re self-employed).

How to find your BIC code or CU

View your current CU in MyACC for Business. If you don’t already have an account registering is easy, all you need is your ACC ID or IRD number. All of your details will be visible once you’ve logged in.

How to find your liable income or payroll

Your liable income or payroll is based on the income information you declared with Inland Revenue on the:

• IR3 Individual income return (for self-employed people)
• IR4 Companies income tax return (for shareholder-employees)
• IR348 Employer monthly schedule (for employers)
• IR7 Partnerships and look through companies (LTCs).

Minimum and maximum income you’ll pay levies on

We set the minimum and maximum levels of liable income on 1 April every year. If your income or your employee’s income is above or below these set amounts, we’ll use this to calculate your levies.

If you’re self-employed

No matter what your employment status, you’ll only pay levies on your liable income up to the maximum level.

Your work hours include all the hours you work per week, even if you have more than one job.

If you work part-time

Part-time work is an average of 30 hours or less a week over a tax year. If you work part-time you won’t be affected by the minimum level. We’ll levy you based on your actual liable income.

If you work full-time

Full-time work is more than 30 hours a week on average over a tax year. If you work full-time and earn less than the minimum over a tax year, we’ll use the minimum amount to calculate your levies for that year.

If you work full-time and earn more than the minimum over a tax year, we'll levy you based on your actual liable income.

If you have income from multiple sources

If you have multiple sources of income, like a mixture of PAYE and shareholder-employee income, you may be eligible for a Multiple Employer Adjustment if the combined earnings in the levy calculation exceed the maximum liable income level for that levy year.  

If your levy calculation is above the maximum liable income level across different sources please contact us by submitting the form below: 

CoverPlus Extra

CoverPlus Extra uses your nominated level of cover instead of your liable income.

Contact us if you need information from previous years.

If you employ staff

You’ll only pay levies on an individual’s earnings up to the maximum level. If an employee on your payroll earns more than the maximum, we’ll only levy you for the maximum.

Contact us if you need information from previous years.

Current levy rates for businesses

We calculate your levies based on your liable income multiplied by your levy rate, per $100 of your liable income. Our levy guidebook has the full list of CUs and their levy rates:

How your claims history affects 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.
