ABN & GST Registration Services
Start Right — Register Your ABN & GST With Confidence
When you’re starting or growing a business in Australia, getting your ABN and GST registration sorted correctly is crucial. At PrepMyBook, we make the whole process simple, clear, and stress-free — so you can focus on running your business, not worrying about paperwork.

What Is an ABN?
An ABN (Australian Business Number) is a unique 11-digit number that identifies your business to the government, other businesses, and the public. You need an ABN to:
- Invoice clients and get paid correctly
- Register for GST
- Claim GST credits
- Avoid having payments withheld by other businesses
What Is GST?
Goods and Services Tax (GST) is a 10% tax on most goods and services sold in Australia.
If your business earns or expects to earn over the GST registration threshold (currently $75,000 per year for most businesses), you must register for GST with the ATO.
When Do You Need GST Registration?
- Your business turnover exceeds the GST registration threshold
- You want to claim GST credits on business expenses
- You run a taxi or rideshare service (must register for GST regardless of turnover)
- You want to look more professional when dealing with other businesses
