The Answer
🏪
ABN, GST, business name, insurance, and state-specific registrations for starting a business in Western Australia.
Step-by-Step Checklist
- Choose your business structure — sole trader (simplest), partnership, company (Pty Ltd), or trust. Most small businesses start as sole traders.
- Register your ABN — free at abr.gov.au. Takes 5 minutes. You need this before you can invoice.
- Register your business name — $39 for 1 year, $92 for 3 years at asic.gov.au (unless trading under your personal name)
- Register for GST — required if your turnover exceeds $75,000/year. Optional below that. Register through the ATO.
- Open a business bank account — keep business and personal finances separate from day one
- Get insurance — public liability ($300–$800/year) and professional indemnity if you provide advice/services
- Set up accounting — use Xero, MYOB, or QuickBooks. Track every expense from day one.
Tax as a Business Owner
As a sole trader, your business income is your personal income — same tax brackets as employees. You pay quarterly PAYG instalments once the ATO issues a notice. GST is reported quarterly via Business Activity Statements (BAS).
State Requirements — WA
- Check if your industry requires a state licence (e.g., builders, electricians, food businesses, real estate agents)
- Council permits may be needed for home-based businesses, signage, or food preparation
- Workers compensation insurance is compulsory in WA if you hire employees
Frequently Asked Questions
Do I need an ABN?
If you're running a business, yes. It's free and takes 5 minutes to register at abr.gov.au.
When do I need to register for GST?
When your turnover reaches $75,000/year (or $150,000 for non-profits). Below that, registration is optional but can be beneficial for claiming GST credits.
Do sole traders pay a different tax rate?
No. Sole traders pay individual income tax rates on their business profit. There's no separate small business tax rate for sole traders.
