How To Start An Accounting Practice: Legal Essentials For Setting Up Your Business In Australia

Starting your own accounting practice in Australia is an exciting move. You get to work with diverse clients, set your own direction and build a brand that reflects your values and expertise.

But a successful practice needs more than technical skills or a strong network. Getting the legal building blocks right from day one - your business structure, registrations, professional obligations, contracts and data protection - will make a big difference to how smoothly you launch and grow.

In this guide, we’ll walk through the practical legal steps to set up an accounting practice in Australia, so you can move forward with confidence and stay compliant as you scale.

What’s Involved In Starting An Accounting Practice - And Is It Feasible?

When we talk about starting an accounting practice, we mean a business offering services such as bookkeeping, payroll, BAS and GST compliance, financial reporting and taxation-related services to individuals, businesses or both. You might begin on your own, with a co‑founder, or plan to build a team over time. You can operate remotely, from a home office, or in a physical office - the core legal steps are similar either way.

Is it feasible? In short, yes - demand for accounting and bookkeeping support in Australia is steady, and trusted firms often grow by word of mouth. The practices that do best tend to combine technical capability with clear positioning, strong client experience and robust legal foundations.

As you test your idea and plan your launch, map out a simple plan that covers:

• Services and scope: bookkeeping, BAS, advisory, tax compliance, payroll, CFO services or niche offerings (for example, hospitality or trades).
• Target clients: individuals, micro/small businesses, specific industries, or high‑growth startups.
• Pricing and profitability: fixed fees, retainers or hourly rates - and what’s included for each.
• Tools and workflow: cloud accounting platforms, secure client portals, engagement and billing processes.
• Legal and risk: structure, registrations, insurance, contracts and data security.

Documenting these basics will guide your setup decisions and help you avoid common pitfalls later.

Step‑By‑Step: Setting Up Your Accounting Practice

1) Choose A Business Structure

Your structure affects liability, tax and how you bring in partners or investors. Common options are:

• Sole trader: simple and low cost, but you’re personally liable for business debts.
• Partnership: two or more people carry on business together and share profits and responsibilities; partners are generally jointly liable.
• Company (Pty Ltd): a separate legal entity that provides limited liability and can support growth, hiring and investment. It comes with extra setup and ongoing obligations.

If you plan to trade under a name that’s different to your legal name (for sole traders) or different to the company’s registered name, you’ll also need to register a business name. It can be useful to understand the difference between a business name vs company name as you decide how you’ll present your brand.

Tip: a company can operate under the replaceable rules in the Corporations Act, or you can adopt a tailored Company Constitution if you want more control over decision‑making and governance.

2) Register Your Business Details

Once you’ve chosen a structure, line up your registrations. Most businesses will need an Australian Business Number (ABN). Having an ABN helps with invoicing, tax and supplier relationships - and there are practical advantages of having an ABN even at the early stage.

If you set up a company, you’ll obtain an Australian Company Number (ACN) during incorporation. You may also need to register for GST if your turnover meets the threshold (or earlier if it suits your business model) and set up PAYG withholding if you’ll have staff.

Only register a business name if you trade under a name that’s different from your personal name (sole trader) or different from the full company name. If you trade under your own name or your company’s name, a separate business name registration isn’t required.

3) Confirm Professional Pathways And Scope

Think about which services you’ll offer and what registrations that triggers. For example, if you’ll provide tax agent services or lodge BAS, you’ll need to engage with the TPB pathways (covered below). If you’ll keep your scope to bookkeeping only, your compliance pathway will be different. Planning your scope will also inform your engagement terms and pricing models.

4) Set Up Secure Systems And Processes

Establish your client onboarding process, file storage (preferably in Australia or with robust protections), password management, access controls and incident response plans. Accounting practices hold highly sensitive information - setting strong processes now reduces risk and builds client trust.

5) Put Your Core Legal Documents In Place

Before taking on clients, prepare a clear engagement letter and service terms, ensure you have a Privacy Policy and build a simple, compliant website. If you’ll hire staff or contractors, line up the right agreements and workplace policies. We cover key documents in detail later in this guide.

6) Plan For Hiring And Workplace Obligations

If you’ll employ staff, get across Fair Work obligations and set clear expectations in each Employment Contract. Even if you start solo, it’s helpful to map out what roles you may need and when, so you can scale smoothly.

7) Consider Buying An Existing Practice Instead Of Starting From Scratch

Buying a client book or an established practice can be a faster route to market. If you explore this path, you’ll want thorough legal due diligence and a careful review of the purchase agreement, including client retention terms, assignment of contracts, staff transfers and any restraints or handover obligations.

Do You Need Any Licences Or Registrations?

What you need depends on the services you offer. Common scenarios include:

• Tax agent registration (TPB): Required if you provide tax agent services, such as preparing or lodging tax returns or giving tax advice to clients for a fee. The TPB sets eligibility and experience criteria.
• BAS agent registration (TPB): Required if you provide BAS services for a fee (for example, GST, PAYG or superannuation guarantee reporting).
• Financial services licensing: If you go beyond standard accounting services into financial product advice, you may need an Australian Financial Services Licence (AFSL) or to be an authorised representative. This is a specialised regime - get advice if you’re unsure.
• Professional membership: Membership of CPA Australia, CA ANZ or IPA is not legally mandatory to serve the public as an accountant or bookkeeper, but it may be required to use certain titles or for specific programs and can be a valuable credibility signal.
• Local permits: If you operate from premises, check any council planning or signage requirements in your area.

Make sure any registrations are kept current and that your engagement terms align with your permitted scope of services.

What Laws And Ongoing Compliance Apply?

Accounting practices touch on several legal areas from day one. Here are the key obligations to have on your radar.

Australian Consumer Law (ACL)

If you sell services to consumers or small businesses, the Australian Consumer Law applies to your advertising, pricing and service guarantees. You must not mislead or deceive - think carefully about website promises, testimonials and proposals - and your contract terms should be fair and transparent. For context on misleading conduct, see section 18 principles under the ACL in our guide to misleading or deceptive conduct.

Privacy And Data Protection

Accounting practices handle highly sensitive personal information - including tax file numbers (TFNs), financial records and identity documents. Even if a business is under the usual $3 million turnover threshold, the TFN rules under the Privacy Act require you to handle TFNs in accordance with the Australian Privacy Principles (APPs). Many practices also choose to comply with the APPs as a matter of best practice and client expectation.

In practice, you should publish a clear Privacy Policy, implement secure storage, limit access to “need to know” only, and have a process to respond to data breaches. If you send email marketing or run a website, make sure your consent and opt‑out processes are compliant.

Employment And Workplace Laws

If you hire, Fair Work laws apply to minimum pay, hours, leave and termination. Provide a written Employment Contract to each staff member and maintain appropriate policies for conduct, leave, devices and confidentiality. Superannuation, workers’ compensation and work health and safety obligations will also apply.

Intellectual Property (IP) And Brand Protection

Your brand name, logo, website content and any proprietary templates or methodologies are IP assets. To protect your brand, consider trade mark issues early - explore relevant trade mark classes and whether to register your name or logo to stop others using confusingly similar branding. Beyond trade marks, make sure you own or licence the content you use (for example, website copy, images and software).

Tax And Financial Reporting (For Your Own Practice)

While you’ll know the tax landscape well, don’t forget your practice’s own compliance - GST (if applicable), PAYG withholding, company tax returns (for companies), and accurate record‑keeping. For tax advice specific to your situation, engage your accountant or the TPB; Sprintlaw can assist with your legal setup and contracts.

What Legal Documents Will Your Accounting Practice Need?

The right legal documents protect your business, set expectations and reduce disputes. At a minimum, most practices should consider the following.

• Client Engagement Letter/Service Terms: Sets the scope of work, responsibilities, timelines, deliverables, fees and payment terms, limits of liability, reliance on client information and your process for variations or additional work. Tailor different versions for bookkeeping, BAS and advisory, as needed.
• Privacy Policy: Explains how you collect, store, use and disclose personal information (including TFNs where relevant) and how clients can access or correct their data. A clear, accessible Privacy Policy supports compliance and client trust.
• Website Terms & Conditions: Covers acceptable use, IP ownership, disclaimers and liability for your website and any client portal. Clear site terms reduce risk, especially where resources or calculators are provided. See Website Terms and Conditions.
• Employment Contract (and Policies): If you employ staff, each employee should have a written Employment Contract and you should implement policies for confidentiality, conflicts, remote work, device use and leave.
• Non‑Disclosure Agreement (NDA): Useful when sharing confidential information with contractors, software vendors or potential referrers. An NDA helps protect sensitive client and business information.
• Partnership Agreement or Shareholders Agreement: If you’re going into business with others, set the rules early. A Partnership Agreement (for partnerships) or a Shareholders Agreement (for companies) should cover decision‑making, profit sharing, exits, restraints and dispute resolution.
• Supplier/Software Agreements: Review terms for your core software (for example, cloud accounting platforms) and any outsourced services. Check data handling, uptime commitments and liability caps align with your risk tolerance and obligations to clients.
• IP And Brand Protections: If you’ve settled on a name and logo, consider trade mark protection so competitors can’t ride on your brand equity. Align your trade mark strategy with the relevant trade mark classes for professional services.

Not every document will apply to every practice, but having the right mix tailored to your services will reduce risk and make onboarding clients smoother.
