Legal Essentials For Setting Up A Partnership In Australia

Setting up a partnership in Australia is a popular way for friends, colleagues or family to launch a venture together. From a shared café to a professional practice, partnerships let you combine skills and share responsibilities without the heavier compliance burden of a company.

That said, there are still important legal boxes to tick. Getting the structure, registrations and documents right from day one can help you avoid disputes, protect your brand and set clear expectations between partners.

In this guide, we explain what a partnership is, the practical steps to start one in Australia, the key laws you’ll need to follow, and the core documents that protect both the business and your partnership relationship.

What Is A Partnership In Australia?

A partnership is a business structure where two or more people carry on a business together with a view to profit. In most cases, there can be up to 20 partners (with certain professional exceptions).

Unlike a company, a partnership is not a separate legal entity. This has some important consequences:

• Shared profits and losses: Partners share the business profits (and losses) according to the proportions agreed between them.
• Joint and several liability: Each partner can be personally liable for partnership debts and obligations, including those incurred by another partner acting for the business.
• Flow-through tax: The partnership doesn’t pay income tax itself, but it must lodge a partnership tax return. Each partner then includes their share of partnership income (or loss) in their individual tax return.
• Simplicity and flexibility: Partnerships are generally easier and cheaper to set up than companies, with fewer ongoing formalities.

This structure works well when trust is high, roles are clear and you want a straightforward way to start trading together. If you need investor capital or stronger liability protection, you may wish to compare a partnership with a company before you commit.

Planning Your Partnership: Roles, Money And Decision-Making

Before you deal with forms or registrations, align on a few fundamentals. Having these conversations early helps prevent misunderstandings later and makes drafting your partnership agreement much smoother.

• Vision and goals: What are you building and why? Agree on your market, offering and how you’ll measure success.
• Contributions: Clarify who contributes what (cash, assets, IP, time, specialist skills) and whether those contributions are reimbursed or recognised in the profit split.
• Profit and loss split: Decide your percentages and timing of distributions. You can use any split that suits you, provided it’s clearly documented.
• Roles and responsibilities: Who is responsible for sales, operations, finance, compliance and strategy? Capture this in writing to keep accountability clear.
• Decision-making: Will major decisions require unanimity or a majority? Who has day-to-day authority to sign contracts or spend money?
• Dispute resolution: Outline a practical pathway for resolving disagreements (for example, negotiation, then mediation).
• Exit and succession: If someone wants to leave (or you bring in a new partner), how are valuations handled and who can buy their interest?

Documenting these points in a business plan and, critically, in a tailored Partnership Agreement sets your partnership up for a smoother start.

Step-By-Step: How To Set Up A Partnership In Australia

1) Confirm A Partnership Is The Right Structure

Australia’s common business structures are:

• Sole trader: One person trading in their personal capacity. Simple, but no co-owners.
• Partnership: Two or more people in business together. Lower compliance, but partners have personal liability.
• Company: A separate legal entity with limited liability for shareholders, but higher costs and compliance.

If you want simplicity and shared workload, a partnership is often suitable. If you want personal asset protection, plan to raise capital, or anticipate significant risk, consider a company now or a future conversion.

2) Choose Your Partnership Name (And Check Availability)

You can trade under the partners’ personal names (e.g. “Smith & Jones”) without extra steps. If you’ll use a different name (e.g. “Star Café”), you’ll need to register a business name with ASIC. You can manage this through Sprintlaw’s Business Name service.

3) Get An ABN For The Partnership

Most partnerships carrying on an enterprise in Australia will need an Australian Business Number (ABN). The ABN is used to issue tax invoices, interact with the ATO and many suppliers, and it’s commonly requested by banks and platforms. You can read more about the practical upsides in our guide to the advantages and disadvantages of having an ABN.

When applying, you’ll provide details of each partner and your business activities. If your expected turnover is at or above the GST threshold, you’ll also register for GST at this stage.

4) Apply For A Partnership TFN And Understand Your Tax Lodgements

A partnership needs its own Tax File Number (TFN) and must lodge an annual partnership tax return. The return shows the partnership’s net income (or loss) and how it’s distributed. Each partner then includes their share in their own tax return.

Important: Sprintlaw provides legal help, not tax advice. For tax registrations and reporting specific to your situation (including GST, PAYG and FBT), speak with a registered tax adviser or the ATO.

5) Register For GST, PAYG And Other Taxes (If Required)

Consider the registrations that apply to your business activities:

• GST: Compulsory once your GST turnover reaches $75,000 (or earlier if you choose).
• PAYG Withholding: Required if you hire employees or certain contractors.
• FBT: If you provide fringe benefits to staff.

Even if you’re just starting out, it’s smart to forecast turnover and staffing so you register on time and avoid penalties.

6) Open A Partnership Bank Account

Open a bank account in the partnership’s name to separate personal and business finances. Banks typically ask for your ABN, business name registration (if applicable) and your Partnership Agreement. While not a legal requirement to have a separate account, it’s best practice for clean bookkeeping and audit trails.

7) Put Your Partnership Agreement In Place

A written Partnership Agreement is the backbone of your relationship. Without one, you fall back on default state or territory Partnership Act rules, which may not reflect what you want.

Your agreement should cover contributions, profit shares, decision-making, authority to bind the partnership, dispute resolution, partner exits and admission of new partners. Getting this tailored by a lawyer reduces risk and gives you clarity from day one.

What Laws And Rules Apply To Partnerships?

Partnership Acts And Authority To Bind

Partnerships are governed by the Partnership Act in each state or territory. These Acts set out default rules (including partner duties and authority to bind the partnership) and how dissolution can occur. Your Partnership Agreement can modify many of these defaults, so it’s worth being deliberate about what you want to keep or change.

Business Names And Marketing Claims

If you trade under a name that isn’t just the partners’ personal names, keep your business name registration current. Any advertising or claims you make must comply with Australian Consumer Law (ACL), which prohibits misleading or deceptive conduct. Our guide to misleading or deceptive conduct explains the key elements to keep in mind when you promote your products or services.

Consumer Guarantees And Refunds

When you sell to consumers, the ACL also imposes consumer guarantees (e.g. goods are of acceptable quality, services are provided with due care and skill). These guarantees apply regardless of your refund or warranty policy, so ensure your customer-facing terms reflect the law.

Employment Law And Workplace Safety

If you hire staff, you’ll need compliant contracts and to meet your Fair Work obligations (minimum pay, entitlements and record-keeping). Start with a tailored Employment Contract and add policies as you grow. You must also follow WHS/OHS rules in your state or territory.

Privacy And Data Protection

The Privacy Act 1988 (Cth) generally applies to Australian Privacy Principles (APP) entities, which typically includes businesses with over $3 million in annual turnover and certain smaller businesses in specific industries or activities. Even if you’re a small partnership under the threshold, it’s good practice to be transparent about how you collect and use personal information.

Publishing a clear Privacy Policy and following it builds customer trust and supports compliance if the Act applies to you (or if you opt in contractually with larger clients).

Intellectual Property And Brand Protection

Your name, logo and other brand assets are valuable. Consider applying to register your trade mark to stop others using a confusingly similar brand. If you sell products, you may also need to consider designs or copyrights depending on what you’ve created.

Licences, Permits And Local Approvals

Depending on your industry, you might need food business permits, professional registrations, council approvals for premises or signage, or other sector-specific authorisations. Check local requirements before you launch to avoid delays or fines.

What Legal Documents Does A Partnership Need?

The right contracts reduce risk, set expectations and keep money flowing on time. While every business is different, most partnerships should consider the following:

• Partnership Agreement: Defines roles, contributions, profit shares, decision-making and exit processes. This is essential to manage risk between partners.
• Business Name Registration: If using a trading name, your ASIC registration should match how you present to customers.
• Customer or Client Terms: Clear Customer Contract, Service Agreement or online terms set scope, deliverables, payment, IP ownership, warranties and liability limits.
• Website Legal Pack: If you operate online, have Website Terms and Conditions alongside your Privacy Policy.
• Supplier/Contractor Agreements: Set quality, delivery times, pricing, IP and confidentiality with key suppliers and independent contractors.
• Employment Contracts & Policies: Use a compliant Employment Contract for each employee and add policies as needed (leave, conduct, devices, etc.).
• Non-Disclosure Agreement (NDA): Use an NDA when sharing confidential information with prospective partners, suppliers, investors or contractors.
• IP Assignment or Licence: If any partner contributes pre-existing IP (e.g. software code or branding), capture ownership or licensing in writing so there’s no ambiguity later.

Not every partnership needs every document on day one, but most will benefit from a tailored core set. If you’re unsure where to start, our team can help you prioritise what’s essential for your industry and growth plans.

Special Scenarios: Adding Partners, Exits And Converting To A Company

Adding Or Removing Partners

When a partner joins or leaves, update your Partnership Agreement, notify relevant third parties (banks, key customers, suppliers) and adjust your ABN and tax registrations where required. If someone exits, ensure the valuation method and payment terms are followed exactly as set out in your agreement.

Authority To Bind And Signing Documents

Be clear on who can sign contracts for the partnership. Your Partnership Agreement should define spending thresholds, when multiple signatures are required and who can represent the business in negotiations.

Converting To A Company Later

Many partnerships later convert to a company for liability protection, investor readiness or tax planning reasons. Conversion has legal and tax implications, so speak with both a lawyer and a registered tax adviser before you change structures. You may also want to introduce a Shareholders Agreement at that stage, which is the company equivalent of a partnership agreement.

Key Takeaways

• A partnership is simple and flexible, but partners can be personally liable for business debts and obligations.
• You don’t “register a partnership” as such; you typically secure an ABN, apply for a partnership TFN, lodge annual partnership tax returns and register a business name if you use one.
• A tailored Partnership Agreement is essential to set profit shares, decision-making, authority and exit pathways.
• Comply with core laws from day one: Australian Consumer Law, employment and workplace safety rules, privacy obligations where applicable, and any industry licences or permits.
• Protect your brand and operations with the right documents, including customer terms, Privacy Policy, Website Terms and Conditions and an NDA.
• Plan ahead for changes like admitting new partners or eventually converting to a company, so you’re ready when growth arrives.
• For tax specifics (GST, PAYG, FBT and returns), consult a registered tax adviser - Sprintlaw provides legal support, not tax advice.
