The ACC Gap Most Business Owners Miss

For most self-employed New Zealanders, ACC feels automatic. You pay your levies – You’re covered for accidents. And if something happens, you expect that ACC will pay 80% of your income.

Simple… right? Not quite.

Many business owners are surprised to learn that ACC weekly compensation is not based on what your business earns – it’s based on what you personally declare as taxable income. That distinction matters more than most realise.

How ACC Calculates Weekly Compensation

Under New Zealand law, the Accident Compensation Corporation (ACC) provides weekly compensation if you are unable to work due to a covered injury.

The general rule for self-employed people is ACC pays up to 80% of your taxable income.

For business owners, taxable income is typically based on:

• Earnings declared to Inland Revenue (IRD)
• Your most recently completed financial year
• In some cases, an average of previous years

ACC does not calculate compensation based on:

• Business turnover
• Company profit
• Cash flow
• What you draw when needed
• What your household actually requires

It is based on declared taxable income.

Why This Can Create a Gap

Many business owners structure income strategically. They may:

• Minimise personal taxable income
• Leave profit in the company
• Reinvest earnings into growth
• Take modest drawings

From a tax perspective, that can make sense. However, if your declared income is lower than your true lifestyle costs, ACC compensation may also be lower than expected.

Example

If your declared taxable income is $60,000: ACC may pay up to 80% – approximately $48,000 per year (before tax).

But if your household requires $100,000 per year to operate comfortably, there is a clear shortfall. When you’re self-employed, income can stop immediately if you cannot work. Mortgage payments, rent, insurance, utilities and family expenses do not.

The Timing Factor

Another detail often overlooked is timing. ACC compensation is usually based on your most recently completed tax year. So if:

• Your income has recently increased
• Your business has grown
• You’ve taken on additional financial commitments

Your compensation may still reflect an earlier, lower income year. For fast-growing businesses, this lag can mean being unintentionally under-covered.

Your Opinions

Self-employed individuals are typically covered under standard ACC CoverPlus. However, ACC also offers CoverPlus Extra, which allows eligible business owners to agree on a set level of cover in advance rather than relying solely on declared income.

Some business owners also consider Private Income and Mortgage Protection to:

• Cover illness
• Top up potential shortfalls
• Provide greater certainty around income

Each situation is different and should be reviewed carefully. The risk isn’t that ACC won’t pay. The risk is assuming it will pay what you think it will.

If you’re self-employed, understanding how your ACC cover works is a key part of protecting both your business and your household. It just takes a simple review with us to have you properly covered.
