Are you sure your GST registration still suits your business as the year closes? Many business owners wait until things get messy before they look at it. You do not need to be one of them. A quick check now can save you money and stress later.
This question comes up a lot at this time of year. The short answer is simple. Yes, you should check your GST registration before the year ends. Your turnover may have changed. Your business activities may look different now. Your tax position can shift with these changes. A few minutes of attention can help you avoid paying too much or missing an obligation.

Below is a practical, expert breakdown to help you work out where you stand.
Why does your GST registration matter right now?
Think about the last twelve months. Did your income jump? Did it drop? Maybe you scaled back work because life got busy. Maybe you pushed harder and picked up more clients. Changes like these can affect whether you should stay registered, register for the first time, or cancel.
A lot of business owners assume things are fine because they have not received a message from the ATO. That assumption can cost money. You might be paying GST when you do not need to. You might be missing a legal obligation without realising it. Neither situation feels great when you discover it at tax time.
Do you need to register for GST?
Under Australian law, you must register if your GST turnover is $75,000 or more in a financial year. This threshold catches people off guard. Many trades, creatives, coaches and online sellers hit it faster than expected. If your turnover is at or above this point, registration is not optional. You must charge GST on taxable sales. You must issue tax invoices. You must lodge your BAS.
If you are close to the threshold, ask yourself a simple question. Could one big job or order push you over? If the answer feels like a yes, it is time to reassess your position.
Can you cancel your GST registration if you are below the threshold?
Yes, you can cancel if your GST turnover is under $75,000. A lot of small business owners keep their registration out of habit. That habit can cost real money. Once you cancel, you stop charging GST. You also stop claiming GST credits. This can feel like a relief if your record keeping has been hard to manage.
Before cancelling, think about your plans. Are you expecting new contracts soon? Are you planning to grow? If your income is likely to lift soon, it may be better to stay registered. If you expect a quiet period, cancellation may help you keep things simpler.

What if you stopped trading?
If you have stopped your business activity, the ATO expects you to cancel your GST registration within 21 days. Many people forget this part. They close their shop or wrap up their services but leave the registration active. This leads to missed BAS lodgments and old debt that never needed to exist. A quick cancellation prevents avoidable headaches.
Are you a taxi or ride share driver?
If you drive a taxi or provide ride-sourcing services, you must be registered for GST no matter your turnover. This rule catches a lot of part-time drivers who think the threshold applies to them. It does not. Even one shift a week still requires registration once you are driving for fares.
Updating or cancelling your GST registration
You can handle it through Online services for business. You can also ask your registered tax or BAS agent to help. If you are unsure which option suits you, speak with your adviser. A short call often prevents mistakes.
What happens if you ignore your GST position?
Picture two business owners at the end of the year. One checks their GST status and fixes a small issue early. The other puts the task aside and hopes things are fine. The first one feels in control. The second one is hit with an unexpected bill three months later.

Which one do you want to be?
Ignoring your GST position can lead to:
- Missed lodgments
- ATO penalties
- Paying GST you did not need to pay
- Losing GST credits because your registration was cancelled too late
- Stress that could have been avoided with a short review
It is a simple check. Yet the impact of missing it can be big.
What should you do now?
Ask yourself three quick questions.
- Has my turnover gone above or below the $75,000 threshold?
- Am I still trading in the same way I was last year?
- Do I feel confident that my GST registration matches my current situation?
If any of your answers feel uncertain, take a moment to check your status. The process is simple. The peace of mind is worth it.
Frequently Asked Questions
Do hobby businesses need GST registration?
No. If your activity is a hobby and not a business, GST does not apply. If you earn regular income and plan to grow, you may be operating a business. That can change your obligations.
Do grants count toward the GST threshold?
Some grants do count. Others do not. It depends on the type of grant and its purpose. If you received a grant, check the ATO’s guidance or speak to your adviser.
Can you claim GST credits without being registered?
No. You must be registered to claim credits. If you cancel your registration, your ability to claim credits ends at that point.
How often should you review your GST status?
A quick review every few months is helpful. A detailed check at the end of the year is smart practice for most businesses.
