Australian Freelancer GST Guide 2026

As a freelancer in Australia, understanding GST is essential for staying compliant and managing your cash flow. This guide covers everything you need to know about GST registration, charging GST on invoices, lodging BAS, and claiming GST credits.

What is GST?

GST (Goods and Services Tax) is a 10% tax applied to most goods and services sold in Australia. As a business owner, you collect GST from your customers and pay it to the ATO, while claiming back GST you've paid on business expenses.

Think of yourself as a middleman—you collect GST on behalf of the government and pass it on through your Business Activity Statement (BAS).

Do You Need to Register for GST?

You must register for GST if your annual turnover is $75,000 or more. This applies to all your business income combined, not per client or project.

If you earn less than $75,000, GST registration is optional. Some freelancers choose to register anyway to claim GST credits on business expenses or to appear more established to corporate clients.

How to Register for GST

You can register for GST online through the Australian Business Register (ABR) website or by asking your accountant or tax agent to do it for you. When you register, you'll need to choose how often you'll lodge your BAS:

• Quarterly: Most common for small businesses and freelancers
• Monthly: Required if your annual turnover is $20 million or more
• Annually: Available if you meet certain conditions

How to Charge GST on Invoices

Once you're GST-registered, you must charge 10% GST on most services you provide. You can display this in two ways:

Either way is acceptable, but make sure your tax invoice clearly shows how much GST is included. Most freelancers prefer showing GST separately for transparency.

Lodging Your BAS

Your Business Activity Statement (BAS) is how you report and pay GST to the ATO. If you lodge quarterly, your due dates are:

• July-September quarter: due 28 October
• October-December quarter: due 28 February
• January-March quarter: due 28 April
• April-June quarter: due 28 July

On your BAS, you'll report:

• G1: Total sales (including GST)
• 1A: GST you collected from customers
• 1B: GST you paid on business purchases

If 1A is higher than 1B, you owe the ATO. If 1B is higher, you'll get a refund.

Claiming GST Credits

One major benefit of being GST-registered is claiming back the GST you pay on business expenses. This includes:

• Office supplies and equipment
• Software subscriptions
• Professional services (accountant, lawyer, web designer)
• Business travel and accommodation
• Marketing and advertising

To claim GST credits, you need a valid tax invoice from your supplier (for purchases over $82.50) and the expense must be for your business. Keep all receipts and invoices for your records.
