New Zealand runs one of the plainest consumption taxes anywhere. A single rate of 15 percent sits on almost every sale, with no reduced band for food, no lower figure for power bills, and no annual tweak to keep track of. The rate has not moved since 1 October 2010, when it stepped up from 12.5 percent. What people actually stumble over is the maths on a receipt that already has GST baked in, because pulling the tax back out of a total needs a different sum from putting it on. This guide walks through both directions, sets out the difference between zero-rated and exempt, and covers the rules that catch small businesses and overseas sellers.
One rate, two directions
Putting GST on a bare price is the easy half. Multiply the GST-exclusive figure by 15 percent and add it. A NZ$200 job picks up NZ$30 of GST, so the customer settles NZ$230.
Taking GST back out of a price that already includes it is where the three twenty-thirds rule pays off. Multiply the inclusive total by 3 and divide by 23, and you have the GST portion exactly. A NZ$230 receipt holds NZ$30 of GST, leaving NZ$200 before tax. The fraction is not arbitrary: 15 over 115 cancels down to 3 over 23, so the tax is always three twenty-thirds of any tax-included figure. When you would rather not do it in your head, the New Zealand GST calculator runs either direction on any amount.
Worked examples that check both ways
Most real situations reduce to those same two moves.
- A landscaper quotes NZ$1,500 plus GST for a retaining wall. GST of NZ$225 goes on top, so the invoice reads NZ$1,725. Run it back the other way and 1,725 times 3 divided by 23 returns the NZ$225, confirming the tax already inside the total.
- A NZ$57.49 hardware receipt contains NZ$7.50 of GST, because 57.49 times 3 over 23 rounds to 7.50. The goods themselves were NZ$49.99 before tax.
- Rough mental check: knocking about 13 percent off an inclusive price lands near the pre-tax figure, while the 3/23 fraction gives the precise tax.
If you are pricing work or setting a margin, the markup calculator and the percentage calculator handle the same style of arithmetic for the numbers behind a quote.
Zero-rated is not the same as exempt
A slice of activity carries no GST, but for two reasons that matter to any registered business.
Zero-rated supplies are still taxable sales, just charged at 0 percent. Exports, services physically carried out overseas, duty-free sales to travellers leaving the country, and the first sale of newly refined gold, silver or platinum all sit here. So does the sale of a business as a going concern between two registered parties, along with many land deals between registered persons. Because the sale is taxable, the seller can still claim back the GST paid on its own costs.
Exempt supplies fall outside GST entirely. Financial services such as interest, loans and bank fees, rent on a residential home, penalty interest on an overdue account, and goods donated to a non-profit and later sold by it all count. Here the supplier charges nothing and cannot recover GST on related spending. To a shopper the two look identical at the counter; to the supplier, the label decides whether purchase tax comes back or stays a cost.
One quirk worth flagging: long-stay guests in commercial accommodation such as a motel, once they pass four weeks, have GST applied to only 60 percent of the charge, an effective 9 percent. That case sits outside the ordinary sum.
GST on overseas orders and digital services
New Zealand closed the tax-free-parcel loophole in stages. Since 1 October 2016, overseas suppliers of digital services to New Zealand consumers, from streaming to software subscriptions, have had to charge 15 percent GST. From 1 December 2019 the same treatment reached imported low-value goods valued at NZ$1,000 or less, collected by the offshore seller or the marketplace at checkout. Goods above NZ$1,000 are handled at the border instead, with GST and any duty collected before release. Either way, small overseas purchases no longer slip in untaxed.
When a business has to register
Registration with Inland Revenue becomes compulsory once turnover from taxable activity tops NZ$60,000 in any 12 month period, or is clearly heading that way. Below that line a business can stay out, though plenty register voluntarily so they can reclaim GST on tools, stock and other costs. Once registered, a business files a GST return for its periods and needs valid tax invoices to support the credits it claims. If the real question is what a New Zealand salary leaves in your pocket rather than what GST adds to a price, the New Zealand salary and tax calculator covers PAYE and the ACC levy separately.
How New Zealand’s GST compares
The headline rate is high, but the base is exceptionally broad.
| Country | Consumption tax | Rate | Note |
|---|---|---|---|
| New Zealand | GST | 15% | Single rate, food and power included |
| Australia | GST | 10% | Basic food is GST-free |
| Singapore | GST | 9% | Raised from 8% in January 2024 |
| Japan | Consumption tax | 10% | 8% reduced rate on food and drink |
| United Kingdom | VAT | 20% | Plus 5% reduced and 0% zero rates |
The OECD regularly points to New Zealand as having one of the least riddled consumption taxes in the developed world. Where most systems carve out food or energy, New Zealand taxes them at the full 15 percent and keeps the exceptions to a short list. The trade-off is a higher rate applied more evenly, rather than a lower rate full of holes.
FAQ
What is the GST rate in New Zealand in 2026? GST is 15 percent on nearly all goods and services. It has held at 15 percent since 1 October 2010, when it rose from 12.5 percent, and unlike European VAT there are no reduced bands.
How do I find the GST inside a price? Multiply the GST-inclusive amount by 3 and divide by 23. Because the rate is 15 percent, the tax is exactly three twenty-thirds of the total, so a NZ$230 receipt holds NZ$30 of GST.
What is the difference between zero-rated and exempt? A zero-rated sale, such as an export, is taxable at 0 percent, so the seller can still claim back GST on its costs. An exempt supply, such as residential rent, sits outside GST, and the supplier cannot recover GST on related spending.
Do I pay GST on things I buy from overseas? Usually yes. Digital services have carried 15 percent GST since October 2016, and imported goods of NZ$1,000 or less have since December 2019, collected by the seller or platform at checkout. Higher-value goods have GST collected at the border.
When does a business have to register for GST? Once turnover from taxable activity passes NZ$60,000 in any 12 month period, or is expected to. Below that, registration is voluntary, which many small operators choose so they can reclaim GST on their costs.
