Australia keeps its sales tax refreshingly simple. One rate, 10 percent, sits on most goods and services, and it has not moved since the goods and services tax began on 1 July 2000. There are no reduced bands to choose between, no province-by-province patchwork, and no annual rate tweak to track. What trips people up is not the rate but the arithmetic: because Australian shelf prices already include GST, working out the tax hidden inside a total takes a different sum from adding it on. This guide covers both directions, what escapes GST altogether, and the rules that catch overseas orders and small businesses.
One rate, one shortcut
Every taxable sale carries GST at 10 percent. Adding it is the easy direction: take the price before tax and add a tenth. A $200 service picks up $20 of GST and the customer pays $220.
Pulling GST back out of an inclusive price is where the one eleventh rule earns its keep. Divide the total by 11 and you have the GST component. An $88 receipt holds $8 of GST, leaving $80 before tax. The logic is clean: 10 parts of pre-tax price plus 1 part of tax make 11 equal parts of the final figure, so the tax is always one of those eleven parts. Whenever you need the number in a hurry, the Australia GST calculator does either direction on any amount.
Adding and removing GST in practice
The same two moves cover almost every real situation.
- A tradesperson quotes $1,500 excluding GST for a fencing job. GST of $150 goes on top, so the invoice reads $1,650.
- Run it backwards and the check holds: $1,650 divided by 11 is $150, confirming the tax already sitting inside the inclusive figure.
- A $66 restaurant bill contains $6 of GST, because $66 divided by 11 is $6. The meal itself was $60 before tax.
For mental estimates on an inclusive price, knocking off roughly 9.1 percent gets you close to the pre-tax figure, while dividing by 11 gives the exact tax. If you are lining up quotes or margins, the percentage calculator and the markup calculator handle the same style of sum for pricing decisions.
GST-free is not the same as input taxed
A large slice of everyday spending carries no GST at all, but for two different reasons that matter to businesses.
GST-free sales include most basic food such as bread, milk, fresh fruit and vegetables and plain meat, along with most medical and health services and products, some education courses and materials, exports, and certain water and sewerage services. A business making GST-free sales charges nothing on the sale yet can still claim back the GST on its own costs.
Input taxed sales, chiefly residential rent and most financial supplies, also carry no GST on the sale, but here the seller cannot claim credits for the GST paid on related purchases. For a shopper the two look identical at the till. For the supplier, the label decides whether purchase tax is recoverable or just a cost.
Food classification is famously fiddly. A raw chicken bought cold is GST-free, while the same chicken roasted and sold hot is taxable. The line usually falls between basic groceries and anything prepared, heated or meant to be eaten on the premises.
GST on things you buy from overseas
The one part of the system that has genuinely changed in recent years concerns imports. Since 1 July 2018, GST applies to low value imported goods sold to Australian consumers, meaning items of A$1,000 or less. The 10 percent is collected by the overseas seller or the online platform at the point of sale, so an offshore retailer that sells over the threshold registers for Australian GST and charges it just like a local shop. Goods valued above A$1,000 are handled the other way, with GST and any duty collected at the border before the parcel is released. Either way, the days of small overseas parcels arriving tax-free are gone.
When a business has to register
Registration becomes compulsory once a business reaches A$75,000 in annual GST turnover, or A$150,000 for a not-for-profit organisation. Below that line a business counts as small enough to stay out, though many register voluntarily so they can reclaim GST on equipment and stock. Taxi and ride-sourcing drivers are the exception: they must register from the first dollar, whatever they earn. Once registered, a business reports through its business activity statement and needs a valid tax invoice to claim credits on any purchase over $82.50. If the take-home from that business is the real question, the Australia salary and tax calculator covers income tax and the Medicare levy separately.
How Australia’s GST compares
Australia’s single broad rate is low by international standards and unusually clean, with no tiered bands.
| Country | Consumption tax | Rate | Note |
|---|---|---|---|
| Australia | GST | 10% | Single flat rate, no reduced bands |
| New Zealand | GST | 15% | Also broad, with fewer exclusions than Australia |
| 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 |
| Canada | Federal GST | 5% | Provinces add their own sales taxes on top |
New Zealand runs a higher headline rate but exempts far less, so its GST reaches almost everything. Europe sits higher again and layers reduced rates on top. Australia’s mix of a modest rate and a meaningful GST-free list is closer to Canada’s federal layer than to the British or European model.
FAQ
What is the GST rate in Australia in 2026? GST is 10 percent on most goods and services. It has held at 10 percent since the tax started on 1 July 2000, and unlike European VAT there are no reduced rates to pick between.
How do I work out the GST inside a price? Divide the GST-inclusive amount by 11. Because the rate is exactly 10 percent, the tax is one eleventh of the final price, so a $66 bill contains $6 of GST.
Which items are GST-free? Most basic food, most medical and health services and products, some education courses, exports, and certain water and sewerage services. Prepared or restaurant food is taxable, which is why a raw chicken is GST-free and a hot roast chicken is not.
Do I pay GST on things I order from overseas? Usually yes. Since 1 July 2018 GST applies to imported goods of A$1,000 or less, collected by the seller or platform at checkout, and goods above A$1,000 have GST collected at the border.
When does a business have to register for GST? Once GST turnover reaches A$75,000 a year, or A$150,000 for a not-for-profit. Taxi and ride-sourcing drivers must register from the first dollar regardless of turnover.
