GST for Cleaning Businesses: When You Need to Register
You need to register for GST once your cleaning business's turnover reaches A$75,000 in a 12 month period, or if you expect to reach it. Below that threshold, registration is optional. Above it, it's compulsory, generally within 21 days of crossing the line.
Key takeaways
- Track current and projected GST turnover against the A$75,000 registration threshold.
- Register within 21 days once required and issue compliant tax invoices.
- Voluntary registration can help in some circumstances but adds BAS and pricing obligations.

What GST actually means for your pricing
Once registered, you charge an extra 10% on top of your service price, collect it from clients, and pass it on to the ATO through a Business Activity Statement, usually quarterly. You can also claim back the GST on eligible business purchases, like equipment and supplies, which offsets some of the admin involved.
Should you register before you have to
Some cleaners register early even under the threshold, generally because they're claiming GST back on a significant equipment purchase, or because a commercial client specifically requires GST-registered suppliers. For most solo operators still building toward A$75,000, waiting until you're required to register is the simpler path, since it avoids adding 10% to your pricing before you need to.
How it affects your invoices
A GST-registered business needs to issue tax invoices, which include a few extra required details (your ABN, the GST amount, and the phrase "tax invoice" rather than just "invoice") beyond a standard invoice. Software that generates invoices for you should handle this formatting automatically once you flag that you're registered, rather than you needing to build the template yourself.
Track the threshold every month
GST turnover is not simply the calendar-year total. The ATO considers current and projected turnover across rolling 12-month periods, so review it monthly as the business grows. That gives you time to adjust pricing, invoice templates and BAS preparation before registration becomes urgent.

Frequently asked questions
Short answers to common questions about this topic.
You're required to register within 21 days of realising you'll exceed the threshold, and you may be liable for GST on sales made from the point you should have registered, so it's worth tracking your turnover regularly rather than finding out after the fact.

Do You Need an ABN to Start a Cleaning Business in Australia
Generally, yes. If you're cleaning for clients while carrying on a business, rather than working as an employee on someone else's payroll, you should apply for an Australian Business Number. Eligibility depends on genuinely operating or taking steps to start an enterprise. An ABN identifies the business, supports supplier dealings, and is required before GST registration.
