What is the GST rate in Australia?

Australia has a single standard GST rate of 10%, introduced on 1 July 2000 under the A New Tax System (Goods and Services Tax) Act 1999. There is no reduced rate band as found in many European countries. Certain supplies are either GST-free (0%, with the supplier able to claim input tax credits) or input-taxed (0%, with no input-tax-credit entitlement).

How do I add GST to a net price?

Multiply the net (ex-GST) amount by 1.10. For example, a A$500 net price becomes A$550 gross (A$500 x 1.10). The GST component is A$50 — exactly 10% of the net. This calculator does that arithmetic for you instantly.

How do I remove GST from a GST-inclusive price?

Divide the gross (inc-GST) amount by 1.10 to get the net, then subtract to find the GST. For example, A$550 inclusive gives a net of A$500 (550 / 1.10) and GST of A$50. A quick mental shortcut is to divide the gross by 11 — the result is always the GST component (550 / 11 = 50).

What goods and services are GST-free in Australia?

The ATO defines GST-free supplies broadly. Key categories include basic food (fresh fruit and vegetables, bread, meat, milk, cheese, eggs — but not restaurant meals, hot food or soft drinks), most medical and health services, education courses supplied by recognised institutions, childcare, water and sewerage, exports of goods and services, and medicines listed on the Pharmaceutical Benefits Scheme (PBS). Suppliers of GST-free goods can still claim GST credits on their own purchases.

What is the difference between GST-free and input-taxed?

Both carry a 0% GST rate to the end customer, but the treatment for the business is different. For GST-free supplies, the supplier charges no GST but can claim back the GST paid on related business inputs — so the supply is genuinely untaxed. For input-taxed supplies (mainly financial services and residential rent), the supplier also charges no GST but cannot claim back input tax credits on purchases related to that supply. The practical effect is that the GST cost becomes embedded in the provider's overheads.

Do I need to register for GST in Australia?

You must register for GST if your business has a GST turnover of A$75,000 or more per year (A$150,000 for non-profit organisations). Taxi and rideshare drivers must register regardless of turnover. Once registered, you charge 10% GST on taxable supplies, lodge a Business Activity Statement (BAS) to the ATO, and claim credits for the GST you pay on business purchases.

Whether you are writing an invoice, reconciling a receipt, or checking a supplier quote, the tool instantly shows the net amount (ex-GST), the GST component, and the gross total (inc-GST) — with copy buttons so every figure lands in your spreadsheet or accounting software without transcription errors.

How it works

Australia operates a single-rate GST system. The standard rate is 10%, applying to most goods and services sold in Australia. Unlike the multi-tier VAT structures common in Europe, there is no 5% or 20% band — you either charge 10%, or the supply is GST-free (0%) or input-taxed (also 0% but without input-tax-credit entitlement).

Adding GST (net to gross): The calculator multiplies your net amount by 1.10. The extra 10% is the GST, and the total is the GST-inclusive price your customer pays.

Gross = Net x 1.10

Removing GST (gross to net): The calculator divides the GST-inclusive amount by 1.10 to recover the net, then subtracts to isolate the GST.

Net = Gross / 1.10 — equivalently, GST = Gross / 11

Worked example

A freelance web developer in Sydney quotes a client A$2,000 ex-GST for a project.

Net (ex-GST): A$2,000.00
GST (10%): A$200.00
Gross (inc-GST): A$2,200.00

The client’s purchase order reads A$2,200, and the developer’s tax invoice must clearly show the A$200 GST amount in accordance with ATO requirements.

Now the reverse: you receive a receipt for A$330 inc-GST for office supplies and want to know the GST for your BAS claim.

Gross (inc-GST): A$330.00
Net (ex-GST): A$330 / 1.10 = A$300.00
GST component: A$330 minus A$300 = A$30.00

The quick mental check: A$330 / 11 = A$30.
