Your Guide to GST Registration Australia

If you're running a business in Australia, getting your head around the Goods and Services Tax (GST) isn't just a good idea—it's essential. The big question most business owners ask is: "When do I have to register for GST?"
For most businesses, the magic number is $75,000 in annual turnover. Hit that, and the Australian Taxation Office (ATO) requires you to register. But, as with most things in tax, there are exceptions. Some industries, like rideshare drivers, have to register from the very first dollar they earn.
When Is GST Registration Required in Australia?
So, what triggers the need to register? The ATO lays it out pretty clearly, and it all comes down to how much your business is earning.
As you can see from the ATO's own guidance, the core requirement for most businesses is tied directly to their gross income, or what's known as 'GST turnover'.
The Mandatory Registration Thresholds
The main trigger for compulsory GST registration is your GST turnover. It’s crucial to understand this isn't your profit. It's the total gross income from all your business activities, before expenses are taken out.
The ATO has set a few different thresholds depending on your business structure.
GST Registration Thresholds at a Glance
Here’s a quick summary of the turnover thresholds that make GST registration mandatory. Keeping an eye on these figures is a key part of your financial management.
Entity Type | Mandatory Registration Threshold (Annual GST Turnover) | Special Conditions |
|---|---|---|
Most Businesses | $75,000 or more | This applies to sole traders, companies, partnerships, and trusts. |
Non-Profit Organisations | $150,000 or more | Includes charities, clubs, and societies not operating for profit. |
Taxi & Rideshare | $1 or more | Registration is required from the first dollar earned, regardless of total turnover. |
Once your business either hits or is likely to hit one of these thresholds within a 12-month period, you have 21 days to register for GST.
A critical first step in this journey is making sure you have an Australian Business Number (ABN). You can't register for GST without one. If you need a refresher on your obligations, our guide to ABN and tax return compliance can walk you through the essentials.
What Counts Towards GST Turnover?
Calculating your GST turnover accurately is where many people get tripped up. It includes the total value of all sales and services connected to your Australian business.
However, you exclude the following from your calculation:
Sales that aren't for payment (like certain donations)
Sales not connected with your business activities
Input-taxed sales, such as providing residential rent or financial supplies
Sales that are not connected with Australia
A Word of Advice: Don't wait until you've already passed the $75,000 mark. You need to be monitoring both your current and projected turnover. If you see you're getting close, it’s time to act.
Special Cases and Industry-Specific Rules
Some industries don't follow the standard turnover rules.
The most common example is the taxi and rideshare industry. Under specific ATO rules, anyone providing taxi, limousine, or rideshare services (yes, that includes Uber drivers) must register for GST from day one, no matter how much they earn. This was put in place to ensure a level playing field with traditional taxi services.
These policies are a core part of Australian tax law, making it essential for businesses in these sectors to get their ABN and GST registration sorted immediately.
Should You Register Voluntarily?
What if your turnover is well below $75,000? You still have the option to register for GST voluntarily.
Why would you do this? While it means you'll have to start charging GST on your sales and lodging regular Business Activity Statements (BAS), it also means you can claim back the GST included in the price of your business purchases.
For businesses with high startup costs or significant ongoing expenses (like buying equipment, stock, or materials), this can be a smart move. Claiming these GST credits can provide a real cash flow boost, making it a strategic choice for many new and growing businesses.
A Practical Walkthrough of the GST Registration Process
So, you've figured out you need to register for GST. Maybe you've hit that magic turnover number, or perhaps you've decided it makes strategic sense for your business. Whatever the reason, it's time to get it done. Don't think of it as a bureaucratic chore; see it as a significant step forward for your business.
First things first: you absolutely must have an Australian Business Number (ABN). This 11-digit number is your business's official ID with the government. If you haven't got one yet, that's your starting line. Stop everything and get your ABN sorted out before you even think about GST.
Choosing Your Registration Method
Once your ABN is in hand, you’ve got a few different ways to tackle the actual GST registration. The best path for you really comes down to how comfortable you are with online government systems versus wanting an expert to handle it.
Online via the ATO: This is the most direct approach. You can use the ATO's online services, which you'll typically access through the Business Portal linked to your myGovID. It’s available 24/7, giving you complete control over the process.
With a Registered Tax or BAS Agent: Let's be honest, this is the go-to for many business owners. A professional, like us here at Baron Accounting, can take care of the entire registration. We make sure it's done right from day one, so you don't have to worry about compliance headaches later.
Over the Phone: Yes, you can still call the ATO to register. While it's an option, be prepared for potential wait times. If you go this route, have all your details lined up and ready to make the call as smooth as possible.
To give you a clearer picture, here’s a quick visual guide to how the GST registration journey looks.
As you can see, the process flows from checking if you need to register, getting your documents in order, and then lodging the application. Processing usually takes about two weeks.
Information You Will Need
No matter which method you pick, the ATO will ask for the same core information. Having these details ready beforehand will make the whole thing a lot quicker and less painful.
Your ABN
Proof of identity (a driver's licence or Medicare card will do)
Your business contact details and its structure (e.g., sole trader, company)
An estimate of your GST turnover (both current and what you expect it to be)
The date you want your GST registration to start from
Let’s put this into a real-world context. Say you're a freelance marketing consultant and you've just signed a big new client. Your projected annual income is now set to easily pass the $75,000 threshold. You'd need to gather your ABN and personal ID, log in to the ATO portal, and choose your registration start date. After you submit, you can expect the ATO to confirm your registration within a few days to a couple of weeks.
Key Insight: Choosing your registration start date is a critical decision. You can backdate it to cover a period when you should have been registered. While this means you'll owe GST on sales from that past date, it also allows you to claim GST credits on business purchases you made during that time. You can also set it for a current or future date.
Getting a professional involved can take the stress out of more than just the initial registration. Many business owners find that getting expert help to lodge their tax return online and manage their ongoing Business Activity Statements (BAS) frees up a huge amount of time and mental energy, letting them get back to what they do best—running their business.
Your Responsibilities After Registering for GST
Getting your GST registration sorted is a big step, but it’s really the starting line, not the finish. Now, your focus needs to shift to ongoing compliance. This brings a new set of tasks that are absolutely vital for keeping your business on the right side of the Australian Taxation Office (ATO).
The first big change you'll notice is how you handle your sales. For any single sale of $82.50 (including GST) or more, you now have an obligation to provide a tax invoice if a customer asks for one. This isn't just a simple receipt; it's a specific document that needs to include certain details required by the ATO to be considered valid.
Mastering the Business Activity Statement (BAS)
The cornerstone of your GST duties from here on out is the Business Activity Statement, or the BAS as it's more commonly known. This is the form you’ll use to report the GST you've collected and pay it to the ATO. It's also how you'll claim back any GST you’ve paid on things you bought for your business.
Most new businesses lodge their BAS quarterly. The standard reporting periods are:
Quarter 1: July to September
Quarter 2: October to December
Quarter 3: January to March
Quarter 4: April to June
On your BAS, you’ll report the total GST collected from sales and the total GST credits you're eligible to claim. The difference between these two numbers will tell you if you owe a payment to the ATO or if they owe you a refund.
A Key Takeaway: Start thinking of the GST you collect as money you’re holding in trust for the ATO—it was never really yours. A fantastic habit to get into is opening a separate bank account and transferring 1/11th of all your business income into it. This simple discipline means the funds will always be there when your quarterly BAS payment is due.
A key responsibility after GST registration isn’t just about ticking compliance boxes, but also making sure your business stays financially healthy. This is where effective small business cash flow management becomes even more critical, as you’re now managing funds on behalf of the tax office.
Keeping Records and Claiming Credits
A stress-free BAS lodgement comes down to one simple thing: good record-keeping. If you get organised from day one, you’ll avoid that last-minute panic of trying to find receipts every quarter. It just means diligently keeping track of all your income and expenses.
To make life easier, look into using accounting software or even a well-organised spreadsheet. The aim is to have a clear, running tally of every transaction. This not only makes lodging your BAS a breeze but also gives you a powerful, at-a-glance overview of your business’s financial health.
One of the major perks of being registered for GST is the ability to claim GST credits. You can claim back the GST component on nearly any purchase you make for your business.
Some common examples of purchases where you can claim GST credits include:
Fuel and vehicle running costs (for business use)
Equipment, tools, and machinery
Office supplies and stationery
Phone and internet bills (the business-use portion)
Professional services, like your accounting fees
To claim a GST credit, you must be holding a valid tax invoice for that purchase. This is exactly why being organised with your records is non-negotiable. Without the right paperwork, you can’t claim the credit, which is like leaving money on the table.
Standard vs Simplified GST for Your Business Model
When it comes to GST registration in Australia, it’s definitely not a one-size-fits-all deal. The right path for your business hinges on how you operate—specifically, whether you’re a local Aussie business or a non-resident selling to customers here. Getting your head around the difference between standard and simplified GST is the first critical step to staying compliant and running your business smoothly.
Standard GST Registration: The Go-To for Aussie Businesses
If your business has a physical presence in Australia—whether you're a sole trader, a company, or a partnership—standard GST registration is almost certainly for you. This is the default system. Once your GST turnover looks like it will hit the $75,000 threshold, this is the path you'll need to take.
The big non-negotiable for standard registration? You must have an Australian Business Number (ABN).
Simplified GST: Designed for Overseas Sellers
The simplified system, as its name suggests, was created for a very specific group: non-resident businesses. Think of international e-commerce stores that sell low-value goods directly to consumers in Australia from overseas. This system helps them meet their tax obligations without getting tangled in the full domestic tax system.
The Major Difference You Need to Know
The most significant difference boils down to one thing: claiming back GST.
With the standard system, you can claim GST credits on your business-related purchases and expenses. This is a massive advantage because it reduces the total tax you owe and gives your cash flow a healthy boost.
On the flip side, the simplified GST system doesn’t allow you to claim any GST credits. Its only purpose is to make it easy for overseas businesses to send the GST they collect from Australian customers to the ATO. They don’t need an ABN, but they give up the right to claim those valuable credits.
The Bottom Line: The choice is pretty clear. If your business operates within Australia or even just holds stock here, standard registration is mandatory. It means getting an ABN and lodging regular Business Activity Statements (BAS), but you get the full benefit of claiming GST credits. Simplified GST is strictly for non-resident businesses selling low-value imported goods.
A Side-by-Side Look
Sometimes a direct comparison makes things crystal clear. Let's break down the two systems to help you see exactly where your business fits.
Comparison of Standard vs Simplified GST Registration
This table highlights the key features of each registration type, making it easier to determine the right fit for your business structure and operations.
Feature | Standard GST Registration | Simplified GST Registration |
|---|---|---|
Who It's For | Most Australian-based businesses (sole traders, companies, etc.). | Non-resident businesses selling goods or digital services to Aussie consumers. |
ABN Required? | Yes, an ABN is mandatory. | No, an ABN is not required. The ATO issues a unique reference number instead. |
Claiming GST Credits | Yes, you can claim credits for GST paid on business purchases. | No, you cannot claim any GST credits. |
Main Obligation | Charge GST and lodge regular Business Activity Statements (BAS). | Remit GST collected on sales to the ATO periodically. |
Ultimately, understanding this framework is fundamental. Australia's GST system has a flat 10% rate, and the registration path you must take is defined by your business activities. As you can see, the choice isn't just a preference—it's dictated by how and where you do business.
Future-Proofing Your Business for GST Changes
The world of tax is never static. Laws and thresholds constantly evolve, and smart business owners always keep one eye on the horizon. A crucial part of successful GST registration in Australia isn’t just about meeting today’s rules, but also anticipating tomorrow’s shifts. This forward-thinking approach is what keeps your business compliant and strategically positioned for what’s next.
One of the most significant potential changes being discussed right now involves the GST turnover threshold itself. Staying informed about these developments is what allows you to make proactive decisions instead of being forced into reactive ones.
A Potential Shift in the GST Threshold
The Australian tax landscape might be heading for a major adjustment for small businesses. There's a significant policy development being discussed, prompted by a report from the Australian Parliamentary Budget Office (PBO). The report recommends a substantial increase in the mandatory GST registration threshold, from the current $75,000 all the way up to AUD 250,000, with a proposed start date of 1 July 2025.
So, why the big jump? The core reason is to significantly ease the compliance and administrative burden on Australia's small business and non-profit sectors.
This potential change isn't just about a new number; it has ripple effects across the economy. The PBO anticipates that while this would lower overall GST revenue, the impact would be partially offset by reduced payments to states, higher income tax collections, and lower government admin costs. It's a complex equation.
An Important Consideration: The PBO report contains a crucial insight. It estimates that around 95% of businesses with turnovers between $75,000 and $250,000 that regularly receive GST refunds would likely choose to remain registered voluntarily.
What This Means for Your Business Strategy
What should you do with this information? First, it highlights the real value of voluntary registration. If your business has high operational costs and you consistently claim GST credits, staying registered—even if the threshold skyrockets—will almost certainly be the best move for your bottom line. You don't want to walk away from those valuable GST credit refunds.
Second, it just underscores the need to stay in the loop. As we get closer to 2025, these proposed changes could become official policy. Keeping on top of tax law adjustments is vital for any long-term planning.
While nothing is set in stone just yet, understanding the direction tax policy is heading in allows you to build a more resilient and adaptable business. It’s all about being prepared, not surprised.
Answering Your Top GST Registration Questions
Once you're in business, GST questions are bound to pop up. Your situation changes, your turnover fluctuates, and suddenly you're wondering what it all means for your tax obligations. It's completely normal.
Here, I'll tackle some of the most common and tricky questions I hear from business owners, giving you clear answers to help you stay on the right side of the ATO.
My Turnover Dropped. Can I Cancel My GST Registration?
Yes, in most cases, you can. If your business turnover dips back below the $75,000 threshold (or $150,000 for non-profits), you have the option to cancel your GST registration.
But hold on before you rush to do it. There are a few key things to think about.
The ATO usually wants you to be registered for at least 12 months before you can cancel. More importantly, cancelling has some real financial consequences:
You can no longer claim GST credits on your business purchases. Simple as that.
You’ll need to lodge one final Business Activity Statement (BAS).
You might have to repay GST credits you’ve already claimed on assets you still hold, like a work vehicle or expensive equipment. This is a big one that catches people out.
Because of these implications, it’s always a smart move to have a chat with a tax professional. We can run the numbers and figure out if cancelling is genuinely the best decision for your business right now.
What if I Realise I Should Have Registered for GST Ages Ago?
Don't panic—it happens more often than you'd think. If you find out you crossed the turnover threshold months (or even years) ago and forgot to register, the first step is to contact the ATO and get your registration backdated to the correct date.
This will trigger two things. The bad news first: you'll owe GST on all taxable sales you made from that backdated start date, even if you didn't charge it to your customers. The ATO might also hit you with some penalties and interest for the late registration.
But there's a silver lining. Backdating your registration also means you can go back and claim GST credits on all the eligible business expenses you paid for during that same period. The key is to act quickly to get it sorted. The sooner you fix it, the better your chances of minimising any penalties.
Do I Charge GST to My Customers Overseas?
This is a classic question for anyone selling online or providing services globally. The short answer is: generally, no.
Sales of goods and services to customers outside Australia are usually considered 'GST-free' exports.
This means you don't add the 10% GST to your invoices for these sales. The great part is, you can still claim GST credits for the business costs associated with making those sales.
To qualify, you need to meet the ATO's conditions. For example, for physical goods, you generally need to export them from Australia within 60 days of receiving payment. Always double-check the official ATO guidelines on exports to make sure you're ticking all the right boxes.
