ACC Levy for the Self-Employed: CoverPlus, CPX and the First Invoice

A self-employed carpenter with $90,000 of liable income pays $3,477.60 in ACC levies for the 2026/27 year on standard CoverPlus. The same carpenter with $90,000 of agreed cover on full CoverPlus Extra pays $4,140.00, an increase of 19%, and the weekly compensation on offer goes up by 25%. Both figures are our arithmetic on ACC's published 2026/27 rates.

That trade is the decision most self-employed people never see priced, because the two products are levied on different bases and charged from different columns of the same rate table.

What a self-employed ACC invoice is made of

If you work for yourself in New Zealand you are covered by ACC from the day you start, and you are placed on standard CoverPlus automatically (ACC, retrieved 19 August 2026). Your invoice carries three levies: a work levy set by your classification unit, the earners' levy, and the Working Safer levy that ACC collects on behalf of WorkSafe New Zealand. GST is added and, if you are registered, it is deductible (ACC, retrieved 19 August 2026).

For 2026/27 the earners' levy is $1.52 per $100 of liable earnings and the Working Safer levy is $0.08 per $100, both GST exclusive (ACC Levy Guidebook 2026/27, page 9, retrieved 19 August 2026). Those two are flat for everyone. Only the work levy is yours, and the step-by-step arithmetic is in how to calculate your ACC levy.

CoverPlus and CoverPlus Extra are levied on different things

Standard CoverPlus is levied on your liable income, taken from the income you declared to Inland Revenue. If you cannot work after an accident, ACC pays up to 80% of your taxable income from your most recently completed financial year (ACC, retrieved 19 August 2026).

CoverPlus Extra is levied on an agreed cover amount you settle with ACC in advance, and it pays 100% of that amount before tax. For 2026/27 the minimum agreed cover is $40,401 and the maximum is $125,313 (ACC, retrieved 19 August 2026). There are two CPX options: full compensation, and a lower-levy option called lower levels of weekly compensation, under which payments reduce if you return to part-time work or the business keeps generating income (ACC, retrieved 19 August 2026).

The levy guidebook prints all three rates on the same row. For carpentry services, classification unit 42420, the standard employer and CoverPlus self-employed rate is $1.76 per $100, the CPX lower-levels rate is $2.29, and the CPX standard rate is $2.40 (ACC Levy Guidebook 2026/27, levy rates table, retrieved 19 August 2026).

Total annual ACC levy at $90,000 of liable income or agreed cover, 2026/27 levy year, calculated from the ACC Levy Guidebook 2026/27 rate table with the flat earners' levy of $1.52 and Working Safer levy of $0.08 added and GST at 15% applied. The totals are our arithmetic; ACC publishes the rates, not the totals.

Carpentry services is CU 42420 and accounting services is CU 78420. All rates per $100, GST exclusive; totals GST inclusive on $90,000.

Which one is cheaper per dollar of cover

Comparing the two levy totals on their own is the wrong comparison, because the two products do not buy the same amount of compensation.

On standard CoverPlus, weekly compensation is up to 80% of $90,000, which is $1,384.62 a week gross. On full CoverPlus Extra with $90,000 of agreed cover, it is 100% of $90,000, which is $1,730.77 a week gross (ACC and ACC, both retrieved 19 August 2026). The weekly figures are our arithmetic on those published percentages.

On these published rates, CoverPlus Extra buys weekly compensation slightly more cheaply per dollar than standard CoverPlus does, for both occupations. The reason is arithmetic rather than generosity. The CPX work levy rate is 36% higher than the CoverPlus rate for the carpenter, but the compensation is 25% higher, which on the work levy line alone favours CoverPlus. The earners' levy and the Working Safer levy, however, are charged at the same flat $1.60 combined on the same $90,000 base under either product, while delivering 25% more compensation under CPX. Those two flat lines are large enough to flip the result.

That flip is much stronger for the accountant, whose work levy is almost nothing and whose bill is therefore almost entirely the two flat levies. It is weaker for high-risk classification units, where the work levy dominates and the gap between the CoverPlus and CPX columns is wide in dollar terms.

This comparison assumes the agreed CPX cover is set equal to liable income. Set it higher or lower and the arithmetic moves.

There is no provisional levy on CoverPlus

Business owners often expect the ACC bill they have heard about from employer friends: a wash-up for the year just gone plus a provisional levy for the year ahead. That is the WorkPlace Cover invoice, which employers receive. ACC describes its two components explicitly: a final levy that is "the year end, or 'wash up' for the previous year", and a provisional levy that is "the estimate invoice based on your payroll for the previous year and is adjusted for expected salary increases" (ACC, retrieved 19 August 2026).

Standard CoverPlus does not work that way. ACC's own levy liable earnings policy, released under the Official Information Act, states plainly that "ACC does not issue provisional invoice for CoverPlus (CP) policies" (ACC OIA response GOV-027418, 19 September 2023, retrieved 19 August 2026). ACC's public description of the CoverPlus invoice matches: it lists liable income, the three levy lines and GST, and no provisional component (ACC, retrieved 19 August 2026).

CoverPlus Extra is different again. Because the cover amount is agreed in advance, the invoice can be issued in advance. ACC states you are invoiced soon after accepting your offer letter, and that if you start a new levy year on a CPX policy you are invoiced in April (ACC, retrieved 19 August 2026). CPX is billed forward; CoverPlus is billed backward.

Why the first invoice surprises people

Two published mechanics do most of the damage, and they compound.

The first is timing. ACC invoices you after Inland Revenue passes on your filed return. For a new business, ACC states the invoice "will be triggered when you file your first tax return. This is usually in your second year of business" (ACC, retrieved 19 August 2026). CoverPlus invoices go out around September (ACC, retrieved 19 August 2026). So you can trade for well over a year, covered the whole time, before the first bill arrives, and it arrives at a point where you have already spent the money.

The second is the minimum. If you work full time, which ACC defines as an average of more than 30 hours a week over the tax year, and you earn less than the minimum liable income, ACC levies you on the minimum instead of on what you earned (ACC, retrieved 19 August 2026). For 2026/27 that minimum is $50,501.

Year one of self-employment is exactly where those two collide. A full-time carpenter who took home $20,000 in a start-up year is levied as though the income were $50,501.

Calculated from the ACC Levy Guidebook 2026/27 rates and the published 2026/27 minimum liable income of $50,501 (both retrieved 19 August 2026). Totals are our arithmetic.

Nearly ten percent of a lean first year, on an invoice that arrives after the year has ended. That is the surprise, and it is a rule rather than an error.

There are two published ways out of it. If you genuinely work 30 hours a week or less, tell ACC, because part-time self-employed people are levied on actual income with no floor. And if your income is irregular or you are newly self-employed without an earnings history, ACC identifies CoverPlus Extra as suited to exactly that case, since it lets you agree the cover amount, and therefore the levy, in advance (ACC, retrieved 19 August 2026). The full product comparison is in CoverPlus vs CoverPlus Extra.

The honest limits

The levy rates above are published and exact. Four things around them are not.

GST is our arithmetic. ACC publishes GST-exclusive rates and confirms a deductible GST line on the invoice, but not a worked GST-inclusive total.

The weekly compensation figures assume the compensation base equals the levy base. Under standard CoverPlus it does not necessarily: levies are charged on the income you have just filed, while compensation is calculated from your most recently completed financial year at the time of the accident. In a year when your income has moved, those two are different numbers.

CPX cover levels are constrained. The 2026/27 range is $40,401 to $125,313, so a self-employed person earning above $125,313 cannot agree cover equal to their income, and ACC may ask for financial documentation if the requested cover is above current earnings.

The whole scheme covers accidents, not illness. ACC does not cover illness or conditions related to ageing (ACC, retrieved 19 August 2026), so no amount of levy, on either product, closes that gap. What sits outside it is set out in what ACC does not cover.

The decision underneath the invoice

CoverPlus and CoverPlus Extra decide what ACC pays you after an accident. Neither decides anything about the months you cannot work because of an illness, which is the exposure most self-employed people are carrying without knowing the number.
