What Registrations Do I Actually Need When Starting a Business?

Starting a business is an exciting milestone, but the paperwork can quickly become overwhelming. At Ascent Accountants, we often see new business owners get caught in the "registration trap"—either registering for everything at once (and creating unnecessary admin) or missing critical deadlines that lead to penalties.

Knowing which registrations are mandatory and which are optional depends on your business structure, turnover, and whether you have a team. Here is our high-level guide to the essential registrations you need to consider. 

1. The Foundations ABN & TFN. 

• Australian Business Number (ABN): Your ABN is your business’s unique 11-digit identifier. While not strictly compulsory for everyone, you almost certainly need one. Without an ABN, other businesses must withhold 47% of any payments they make to you. 
• Tax File Number (TFN): 
• Sole Traders: You use your personal TFN. 
• Companies, Partnerships, and Trusts: You must apply for a separate business TFN. 

2. Tax Registrations (ATO) 

• Goods and Services Tax (GST): You must register for GST if your business has a GST turnover of $75,000 or more ($150,000 for non-profits). If you drive a taxi or provide ride-sourcing services (like Uber), you must register regardless of your turnover. 
• Fuel Tax Credits: If your business uses fuel in heavy vehicles, machinery, or for other eligible activities, you can claim a credit for the excise or customs duty included in the price. Note: You must be registered for GST before you can register for Fuel Tax Credits. 

3. Employer obligations when hiring a team. 

If you’re moving from a "solo-preneur" to an employer, your registration requirements change significantly: 

• PAYG withholding: You must register for Pay As You Go (PAYG) withholding before you make your first payment to employees or certain contractors. This allows you to withhold tax from their wages and send it to the ATO. 
• Superannuation: You don't "register" for super in the traditional sense, but you have a legal obligation to pay the Superannuation Guarantee (currently 12% on July 1, 2025) for eligible employees. We recommend setting up a Superannuation Clearing House to streamline these payments. On 1st July 2026, super will be required to be paid each payday. 
• Workers’ compensation insurance: This is a mandatory insurance policy for almost all employers in Australia. It protects you and your employees in the event of a work-related injury. Each state has different rules; for example, in WA, you must have a policy if you employ anyone defined as a "worker." 

4. Business Identity: ASIC 

If you want to trade under anything other than your own legal name (e.g., "John Smith" vs. "Smith’s Landscaping"), you must register the name with the Australian Securities and Investments Commission (ASIC). 

Our advice? Don’t over-register too early. 

We often see clients register for GST before they reach the $75k threshold. While this allows you to claim GST credits on your setup costs, it also means you must lodge regular Business Activity Statements (BAS).
