Starting your own business is an exciting step – a chance to bring your unique idea to life, build something meaningful, and create your own path to success. Australia’s thriving small business sector is filled with inspiring stories of people just like you who turned their ambitions into reality. But as rewarding as running a small company can be, the legal side of launching and managing a business often feels daunting.
You’re not alone if you find the legal requirements for starting a small business overwhelming. Whether you’re at the early small business startup stage, seeking help starting a small business, or ready to take your side hustle full-time, it’s crucial to get the legals right from day one. The good news? With some planning and the right small business advice, you’ll avoid costly mistakes and build a stronger, more resilient business.
In this guide, we’ll walk you through the key legal steps and practical essentials every small business owner in Australia should know. Keep reading for straightforward legal tips – and remember, at Sprintlaw, we’re here to guide you every step of the way.
What Is a Business Venture?
Before diving into setup steps and legalities, let’s quickly clarify what we mean by “business venture.” Broadly, a business venture is any activity undertaken with the intention of making a profit. It could be as simple as selling homemade candles online, running a consulting practice, or launching an innovative tech startup. Whether you see yourself as a sole trader, leading a small business to start, or joining forces with partners, your venture is a genuine commercial operation in the eyes of the law.
If you’re still weighing up ideas, our business vs hobby guide can help clarify when your idea crosses over into a business – and what that means for your legal responsibilities.
How Do I Plan and Set Up a Small Business?
Small business success starts with good planning. Before you leap into legal documents and registrations, take time to research your idea and create a business plan that covers:
- Who your target customers are and what problem you’ll solve
- What your competitors are doing – and how you’ll differentiate
- Your startup costs and expected income
- What licenses, permits, or registrations you might need
- How you’ll manage key risks and comply with the law
A clear plan will keep you focused and reveal any legal or administrative hurdles early, so you can address them before they become problems.
For a step-by-step checklist, see our article on 5 steps to starting a business in Australia. It’s normal to feel uncertain when starting out – but with the right preparation, the process becomes much more manageable.
What Legal Structure Should I Choose?
One of your first major legal decisions is picking the right business structure. This impacts your legal responsibilities, tax obligations, and level of personal risk. In Australia, the most common structures are:
- Sole Trader: You run the business by yourself, keep all profits and are personally responsible for debts and losses. Easiest to set up, but your personal assets are at risk.
- Partnership: Two or more people share ownership and management. Profits, losses and decision-making are split according to your agreement. Partners are usually personally liable for business debts.
- Company: A separate legal entity, registered with ASIC. A company structure limits the personal liability of directors and offers more credibility, but comes with extra paperwork and compliance obligations (learn the difference between an ABN and ACN here).
- Trust: A trust structure can provide flexibility and asset protection, but is more complex. Usually set up for tax reasons or to hold family/business assets safely.
Choosing a structure is a big decision – there’s no “one size fits all.” Many small business owners start as a sole trader for simplicity, but if you plan to scale, bring on investors, or protect personal assets, consider a company or trust. For more detail on structures, see our guide to business names vs company names.
How Do I Register My Small Business?
Before trading, you must register your business with the relevant authorities. The process generally involves:
- Australian Business Number (ABN): Almost all businesses need to apply for an ABN via the Australian Business Register. This unique 11-digit number identifies your business to government and others.
- Business Name: If you trade under a name other than your personal legal name, you must register a business name with ASIC. This does not give you legal ownership or exclusive rights to the name – it’s just a registration.
- Company Registration: If you choose a company structure, you need to register this with ASIC and receive an Australian Company Number (ACN). You’ll also need a company constitution and official company documents.
- Tax Registrations: Register for GST if your turnover is over $75,000, and consider PAYG withholding if hiring employees. Read more about ABN registration here.
- Domain Name: If you plan to operate online, register your domain name to match your business name or brand. For a leg up on digital setup, see our guide to domain name registration.
You can work through these steps yourself, or ask us for help registering your business – we’ll make sure you’re compliant from the beginning.
What Laws Should Small Business Owners Know?
Small businesses in Australia are subject to a range of laws – some general, some industry-specific. Here are the key legal areas you need to consider:
Permits and Licensing
Almost every business requires some approvals – from your local council (e.g. for home businesses or signage), industry regulators (like food or health), or state/federal bodies for certain activities (e.g. liquor licensing). Operating without the required licence exposes your business to closure and fines. Always check what licences you need for your business before you begin.
Australian Consumer Law (ACL)
If you sell goods or services, you’ll need to comply with the ACL. This sets out your obligations around product quality, refunds, warranties, fair advertising, and avoiding misleading conduct. The ACL also covers online stores and digital businesses. We break down the essentials here: Australian Consumer Law for businesses.
Employment Law
Will you hire staff? Make sure you follow minimum wage requirements, workplace safety rules, and issue correct employment contracts. The Fair Work Act and national Modern Awards cover many small business situations. For tips, read our Employee onboarding guide and employment contract templates guide.
Privacy and Data Protection
If your business collects any personal data – even just through a website contact form or email list – you are likely covered by privacy laws. You’ll need a Privacy Policy explaining how you use and protect data.
Intellectual Property (IP)
Your business name, logo, inventions, artwork and website content can all be protected under IP law. Registering a trade mark, for example, is the best way to stop others from copying your brand. Read more about IP protection in our Intellectual Property guide.
Tax and Superannuation
You’ll also need to comply with tax law, report income, and pay the correct GST, PAYG, superannuation and more. Good accounting systems – and sometimes professional advice – are a must.
Each business will face different rules depending on its industry and activities. If you’re unsure, consulting a small business solicitor is always a wise move.
What Legal Documents Will My Startup Business Need?
Having the right legal documents is one of the strongest ways to protect your new business and manage risk. Not every venture will need every contract, but here are the essentials for most Australian small businesses:
- Customer Terms and Conditions: Clearly outline how you provide goods or services, your pricing, payment terms, refunds, and dispute management.
- Privacy Policy: Required if you collect personal information – outlines what data you collect, how you use it, and data protection measures.
- Website Terms of Use: Sets rules for anyone using your website and limits your liability if things go wrong.
- Employment Contract: If you hire employees, written contracts clarify expectations, pay, leave, and workplace policies.
- Supplier or Service Agreement: Essential if you rely on suppliers, manufacturers, or external service providers, so all parties know their obligations.
- Non-Disclosure Agreement (NDA): Protects your confidential info when sharing ideas or plans with others (e.g. developers, designers).
- Shareholders Agreement: If you co-found the business or bring on investors, this agreement outlines profit sharing, decision making, and dispute resolution.
Some industries require other specialist contracts (like franchise agreements or lease agreements for a shopfront). You can find further info and templates for essential business documents in our guide to legal documents.
Remember: using simple templates or copying another business’s terms is risky. Legal documents should reflect your real business activities and Australian law – so always tailor them, and reach out for professional help if you’re unsure.
What Are Common Mistakes Small Business Owners Make?
Starting a business comes with a steep learning curve. Many small business owners trip up on the same legal issues, such as:
- Failing to register the correct structure or licences
- Neglecting written contracts (verbal agreements are hard to enforce)
- Overlooking consumer law and refund obligations
- Not protecting key IP early (trade marks, logos, website content)
- Ignoring privacy and data laws
- Inadequate workplace policies or poor record-keeping
Steering clear of these mistakes can save you costly disputes or penalties in the future. For more on this, see our article on 10 small business mistakes and how to avoid them.
Is Buying a Business or Franchise Easier Than Starting from Scratch?
Not every entrepreneur starts their own venture from the ground up. Buying an existing business or joining a franchise can offer a ready-made client base and proven systems – but these options come with their own legal complexities.
You’ll need to carefully review the business purchase contract, business sale agreement, or franchise contract before committing. This is a situation where seeking legal advice is invaluable. For more info on this process, check out our guide on buying a business in Australia.
