What is Australia's GST Rate in 2026?
Australia's GST rate is 10% — flat on all taxable goods and services, unchanged since 1 July 2000. To add GST multiply the price by 1.1. To find the GST inside a GST-inclusive price divide by 11. Businesses with turnover over AU$75,000/year must register for GST with the ATO and lodge a BAS.

How to Calculate GST on a Number or Total Amount
To calculate GST on a specific number, multiply that number by 0.1 (which is 10%). This gives you the GST amount to add. To calculate GST from a total amount that already includes GST, divide the total by 11 — the result is the GST component already built into that price.
Three common scenarios:
Calculate GST on a number (add GST): AU$350 × 0.1 = AU$35 GST. Total with GST = AU$385.
Calculate GST from a total amount (extract GST): AU$385 ÷ 11 = AU$35 GST. Price without GST = AU$350.
Remove GST from a total amount: AU$385 ÷ 1.1 = AU$350 (ex-GST price).
Use the calculator above to do this instantly for any amount — enter your number, select Add GST or Remove GST, and get the result immediately.
What is GST and How Does It Work in Australia?
GST (Goods and Services Tax) is a broad-based tax of 10% on most goods, services, and other items sold or consumed in Australia. It was introduced on 1 July 2000, replacing the old wholesale sales tax system.
GST works as a multi-stage tax collected at each point of the supply chain — from manufacturer to wholesaler to retailer to end consumer. Each registered business collects GST on their sales (output tax) and claims credits for GST paid on their purchases (input tax credits). Only the end consumer bears the final GST cost — businesses in the chain are effectively tax collectors for the ATO.
Example: A manufacturer sells goods to a retailer for AU$100 + AU$10 GST. The retailer sells to a customer for AU$200 + AU$20 GST. The retailer remits AU$20 collected minus AU$10 credit = AU$10 net to the ATO. The manufacturer remits AU$10. Total GST to ATO = AU$20 — exactly 10% of the final consumer price of AU$200.
How to Calculate GST in Australia
Australia’s GST is a flat 10% tax on most goods and services. There are two calculations every Australian business owner uses regularly.
Adding GST to a price (ex-GST price): Multiply by 1.1. A product priced at AU$200 before GST becomes AU$200 × 1.1 = AU$220 GST-inclusive. The GST component is AU$20.
Finding GST inside a GST-inclusive price: Divide by 11. A receipt showing AU$220 contains AU$220 ÷ 11 = AU$20 GST. The pre-GST price is AU$220 ÷ 1.1 = AU$200.
How to Calculate GST on a Taxable Sale in Australia
All GST calculations in Australia use the standard 10% rate — there are no reduced rates like the UK’s 5% VAT band. A taxable sale is any sale where GST applies. To calculate GST on a taxable sale, multiply the sale price excluding GST by 10%.
For your BAS you need two figures from each taxable sale:
G1 (Total sales): The total GST-inclusive amount received from customers.
1A (GST on sales): The GST component — total sales divided by 11.
Example: You receive AU$11,000 in GST-inclusive sales for the quarter. G1 = AU$11,000. Field 1A = AU$11,000 ÷ 11 = AU$1,000 GST collected. If you paid AU$550 GST-inclusive on business purchases (AU$50 GST in field G11), your net GST payable = AU$1,000 − AU$50 = AU$950 to the ATO.
Who Must Register for GST in Australia?
You must register for GST when your business turnover reaches AU$75,000 in any 12-month period (AU$150,000 for not-for-profit organisations). Taxi and ride-share drivers must register regardless of turnover.
Once registered, you collect 10% GST from customers, report it on your BAS (Business Activity Statement), and remit the net amount to the ATO — after offsetting GST credits on your own business purchases (input tax credits).
What Items Are GST-Free in Australia?
Not everything attracts GST. Main GST-free categories include:
- Basic food — fresh fruit, vegetables, bread, meat, dairy
- Most medical, health, and hospital services
- Most educational courses and childcare
- Exports of goods and services outside Australia
- Residential rent and sale of existing residential property
- Certain financial services and insurance products
Takeaway food, alcohol, restaurant meals, soft drinks, confectionery, and snack foods all attract 10% GST even though they are food items.
GST on Stripe and PayPal Fees for Australian Businesses
Stripe and PayPal both apply 10% GST to their processing fees for Australian-registered businesses. Stripe’s 1.75% + AU$0.30 domestic card fee becomes an effective 1.925% + AU$0.33 once GST is added.
If you are GST-registered you can claim the GST on these processing fees as input tax credits on your BAS. Both Stripe and PayPal issue monthly tax invoices showing the GST component — find them in your billing dashboard under finances or tax invoices.
Frequently Asked Questions — Australia GST Calculator
How do I calculate 10% GST in Australia?
To add 10% GST to a price, multiply by 1.1. To find the GST already inside a GST-inclusive price, divide by 11. To remove GST from a GST-inclusive price, divide by 1.1. Example: AU$330 GST-inclusive ÷ 11 = AU$30 GST. AU$330 ÷ 1.1 = AU$300 pre-GST price. Check: AU$300 × 1.1 = AU$330.
What is the GST rate in Australia in 2026?
Australia’s GST rate is 10% and has not changed since it was introduced on 1 July 2000. There is only one GST rate — a flat 10% on all taxable supplies. Some supplies are GST-free (0%) including basic food, medical services, and education. There is no reduced rate like the UK’s 5% VAT band.
Do I have to register for GST in Australia?
You must register for GST if your business GST turnover is AU$75,000 or more in any 12-month period. For not-for-profit organisations the threshold is AU$150,000. Taxi and ride-share drivers must register regardless of turnover. You can voluntarily register below the threshold — useful if you want to claim input tax credits on business purchases.
How do I find the GST component inside a GST-inclusive price?
Divide the GST-inclusive price by 11. GST is always 1/11th of the GST-inclusive price because the price is made up of 10 parts original price plus 1 part GST (11 parts total). For AU$550: AU$550 ÷ 11 = AU$50 GST. Pre-GST amount = AU$550 − AU$50 = AU$500.
Is GST the same as VAT?
GST and VAT are functionally the same type of consumption tax — collected at each stage of the supply chain, with businesses claiming credits for tax paid on inputs. Australia calls it GST at 10%. The UK calls it VAT at 20% standard rate. New Zealand calls it GST at 15%. The key difference is Australia has a single flat rate whereas the UK has 20%, 5%, and 0% tiers.
Can I claim GST credits on my business expenses?
Yes — if you are GST-registered you can claim input tax credits for GST paid on purchases used in your business. This includes GST on payment processing fees (Stripe, PayPal, eWAY, Square), software subscriptions, office supplies, equipment, and professional services. Claim these credits on your BAS in field G11 and offset against your GST collected in field 1A. Only the net difference is paid to or refunded by the ATO.
How often do I need to lodge a BAS in Australia?
Most small businesses lodge a BAS quarterly — due in October, February, April, and July. Businesses with annual turnover over AU$20 million must lodge monthly. The ATO may also place you on a monthly cycle if you consistently have large GST credits. You can lodge via MyGov, directly through accounting software like Xero or MYOB, or through your registered BAS agent.
Does Stripe charge GST on its fees in Australia?
Yes. Stripe applies 10% GST to all processing fees for Australian-registered businesses — on card fees, BECS Direct Debit fees, and any other Stripe service charges. This GST is itemised separately on your monthly Stripe tax invoice. If you are GST-registered, claim it as an input tax credit on your BAS. If you are not registered, the GST is an additional cost you absorb on top of the processing fee.
What is GST and how does it work in Australia?
GST is a 10% tax on most goods and services sold or consumed in Australia, introduced on 1 July 2000. It is collected at each stage of the supply chain — businesses collect GST on their sales and claim credits for GST paid on their own purchases. Only the end consumer bears the final cost. Registered businesses report and remit net GST to the ATO via their BAS — quarterly for most small businesses.
How do I calculate GST on a taxable sale?
Multiply the sale price excluding GST by 0.1 to get the GST amount, then add it to get the GST-inclusive total. For your BAS, report the GST-inclusive total in field G1 and the GST component (total ÷ 11) in field 1A. All taxable sales in Australia use the standard 10% rate — there are no reduced GST rates unlike the UK which has multiple VAT rates.
How do I calculate GST from a total amount?
Divide the GST-inclusive total by 11. This works because GST is always 1/11th of the GST-inclusive price. Example: AU$770 GST-inclusive ÷ 11 = AU$70 GST. The ex-GST price is AU$770 − AU$70 = AU$700. You can verify: AU$700 × 1.1 = AU$770. Use the Remove GST mode in the calculator above to do this instantly.
