Starting a business with someone else can be exciting. You get to share the workload, combine skills, and (hopefully) grow faster than you could alone.
But when you’re choosing between different partnership structures, it’s easy to focus on the “business” side (roles, customers, revenue) and forget the “legal” side (who’s liable, who owns what, how decisions get made, and what happens if someone wants out).
The right partnership structure can help you build with confidence. The wrong structure can leave you personally exposed, stuck in disputes, or scrambling when things change.
Below, we’ll walk you through the main partnership structures available to Australian small businesses, how they work, and what to consider before you commit.
What Is A Partnership In Australia (And Why Structure Matters)?
In Australia, a partnership is generally an arrangement where two or more people (or entities) carry on a business together, with a view to profit.
That sounds simple, but legally it can get complicated quickly because a partnership can affect:
- Who is responsible for debts: in some partnership structures, you may be personally on the hook.
- Who can make binding decisions: one partner may be able to sign a contract that commits everyone.
- How profits are shared: not always automatically “50/50”.
- Tax treatment: partnerships are commonly treated as “flow-through” for income tax, but the way income is returned and allocated can be technical and fact-specific (and not all arrangements are treated the same).
- What happens when things change: a partner leaving, a new partner joining, or the business being sold.
Because tax outcomes depend on your circumstances, it’s a good idea to speak with an accountant (this article is general information and not tax advice).
It’s also worth remembering that a partnership isn’t the only way to co-own a business. Many co-founders choose to run the business through a company and use a Shareholders Agreement instead, especially if they want limited liability and clearer governance.
Still, partnerships can be a great fit for many small businesses, particularly in early stages.
Types Of Partnerships In Australia: The Main Options For Small Businesses
When people search for “partnership types”, they’re usually referring to the legal structures below. Each has different liability and operational rules, so it’s worth understanding the basics before you choose.
1) General Partnership (Sometimes Just Called “A Partnership”)
A general partnership is the most common partnership structure for small operators.
In a general partnership:
- each partner typically shares in profits (and losses)
- each partner may be able to bind the partnership (for example, by signing contracts in the ordinary course of business)
- liability is usually unlimited - meaning partners can be personally liable for partnership debts and obligations
This is the key trade-off: general partnerships are easy to start and run, but they can come with real personal risk if the business takes on debt, faces a claim, or enters into a bad deal.
If you’re going down this route, a tailored Partnership Agreement is one of the best ways to reduce misunderstandings and set clear rules around money, decision-making, and exits.
2) Limited Partnership (LP)
A limited partnership is a structure that includes:
- at least one general partner (who manages the business and usually has unlimited liability), and
- at least one limited partner (who contributes capital and has liability limited to their contribution, but typically does not take part in management).
This structure is less common for everyday small businesses, but it can be relevant where one party wants to invest funds without being actively involved in running the business.
Because limited partnership rules can vary depending on the state or territory and the way the arrangement is set up, it’s important to get advice early so you don’t accidentally create a structure that doesn’t match how you actually operate day-to-day.
3) Incorporated Limited Partnership (ILP)
An incorporated limited partnership is a more specialised partnership structure that is used in certain contexts (for example, venture capital or investment structures).
Unlike a general partnership, an ILP is registered under state/territory legislation and has “body corporate” status. In practice, this can mean it can hold assets and enter contracts in its own name, and it may continue despite changes in partners (subject to the legislation and its governing documents). However, liability outcomes and obligations still depend on how the ILP is structured and who is doing what (including whether someone is acting as a general partner).
Most traditional “mum and dad” small businesses won’t need an ILP, but it’s still useful to know it exists when you’re reviewing options, especially if you’re planning to raise capital or have passive investors involved.
4) “Partnership” By Behaviour (Unintended Partnerships)
One of the biggest traps we see is when two people start operating informally - sharing income, sharing costs, presenting themselves as a combined business - and only later realise they may have created a partnership without meaning to.
For example, you might think you’re “just collaborating”, but if you’re carrying on a business together and splitting profits, that can start to look like a partnership in practice.
This matters because if you’ve unintentionally formed a partnership, you can also unintentionally take on partnership obligations and liabilities.
If you’re not sure what you’ve actually created, a Legal Health Check can help you confirm what structure you’re operating under and what you should document properly.
5) Joint Ventures (Not Always A Partnership, But Often Confused With One)
A joint venture is often described as two businesses working together on a specific project (for example, developing a product, bidding on a contract, or running a pop-up event together).
Sometimes a joint venture is structured as a partnership. Other times it’s purely contractual (meaning it’s governed by an agreement, and each party stays separate).
The right approach depends on what you’re doing. If you’re teaming up for a specific project (rather than building an ongoing shared business), you may be able to manage risk more cleanly with a tailored joint venture agreement instead of a full partnership.
Key Differences Between Partnership Types (Liability, Control, Tax, And Risk)
When you’re comparing different partnership structures, it helps to focus on a few practical questions. These questions usually reveal which structure actually fits your business.
Who Is Liable If Something Goes Wrong?
This is often the deciding factor.
- General partnerships: partners can be personally liable for debts and claims (including those caused by another partner acting within their authority).
- Limited partnerships: general partners typically carry the most risk; limited partners usually have liability capped (as long as they don’t take on management roles).
- Company alternative: a company can offer limited liability (though directors still have obligations and there are exceptions).
If your business will sign leases, hire staff, provide professional services, or take on significant debt, liability planning becomes even more important.
How Will Decisions Be Made?
Even in the healthiest relationship, decision-making can get messy without rules.
Consider things like:
- Who can sign contracts?
- What decisions require unanimous approval?
- What decisions can be made by a simple majority?
- What happens in a deadlock (50/50 disagreement)?
These issues are much easier to manage when they’re agreed upfront and written down, rather than argued about mid-crisis.
How Are Profits, Losses, And Contributions Handled?
Many small businesses start with informal assumptions like “we’ll just split everything equally”. That can work - until it doesn’t.
You’ll want clarity on:
- how profits are split (and when distributions happen)
- whether partners can take drawings (and any limits)
- what happens if one partner injects extra capital
- whether partners are paid for labour/management time, separate from profit share
This is especially important if one partner is contributing money while the other contributes time, or where contributions will shift over time.
What Happens If Someone Wants Out (Or You Want To Sell)?
Exit planning is often overlooked, but it’s one of the most important parts of any partnership structure.
You’ll want to think about:
- how a partner can retire or resign
- whether a partner can sell their interest to a third party
- how the business (or a partner’s share) will be valued
- what happens if a partner becomes unwell or can’t work
- restraints (like non-solicitation and confidentiality) to protect the business after an exit
If you’re planning on eventually selling the business, it’s also worth thinking ahead about what a buyer will expect to see during due diligence.
How Do You Choose The Right Partnership Structure For Your Small Business?
There isn’t a one-size-fits-all answer. But in practice, choosing between the main partnership structures (or deciding to use a company instead) usually comes down to your goals and your risk profile.
If You’re Keeping It Small And Simple
A general partnership can be a practical option when:
- the business is relatively low risk (no major debt, no high-risk services)
- you’re operating locally and keeping operations straightforward
- you want minimal setup complexity
- you and your partner have aligned expectations and strong communication
Even then, “simple” doesn’t mean “no documents”. A clear written agreement can make day-to-day decisions smoother and reduce disputes.
If One Person Wants To Invest But Not Operate
A limited partnership can work where you have:
- an active operator (general partner), and
- a passive contributor (limited partner) who primarily wants exposure to profits rather than management involvement.
In these setups, the paperwork matters because if a limited partner starts acting like a manager, they may risk losing the benefit of limited liability.
If You Want Growth, Investment, Or Better Risk Separation
Many founders decide that a company structure is a better fit than a partnership, particularly when:
- you want limited liability separation between the business and your personal assets
- you plan to bring in investors later
- you want clearer ownership units (shares) and easier transfers
- you want the business to continue even if one owner exits
This is where Company Set Up and strong internal governance documents can make a big difference.
If you operate through a company, you’ll often also consider a Company Constitution to set rules for how the company is run (and how directors/shareholders interact).
Quick Self-Check Questions Before You Commit
If you’re still deciding which structure is right, ask yourself:
- How much financial risk will the business take on? (leases, loans, inventory credit, warranties)
- Will both partners be equally involved? Or is one more of an investor?
- Do you expect to raise funds or add new owners?
- Do you need the business to survive an owner’s exit?
- How will you resolve disagreements?
If these questions feel hard to answer, that’s normal. It’s also a sign you’re at the stage where getting advice can save you a lot of time (and stress) later.
What Legal Documents Should You Put In Place For A Partnership?
Once you’ve chosen your structure, the next step is documenting it properly. For many small businesses, the legal documents are what turn “a good idea” into a stable business foundation.
Here are common documents to consider, depending on how you’re operating.
Partnership Agreement (For General Partnerships)
This is usually the core document for a partnership. It sets out the rules of the relationship and helps reduce disputes.
A well-drafted Partnership Agreement typically covers:
- profit and loss sharing
- capital contributions and drawings
- roles and decision-making powers
- banking and financial controls
- dispute resolution processes
- exit terms (retirement, removal, sale, death/incapacity)
- confidentiality and restraint protections
Founders Agreement (If You’re Pre-Revenue Or Still Building)
If you’re still validating the business model, building the product, or testing the market, you might not be ready for a full partnership or company structure yet.
In that early stage, a Founders Agreement can help you document key expectations (like ownership, roles, and what happens if someone leaves before launch) while you figure out the best long-term structure.
Customer-Facing Terms (To Manage Operational Risk)
Many partnership disputes aren’t caused by the partners themselves - they’re caused by external pressure from customers, suppliers, or cash flow issues after a disagreement with a third party.
If you’re selling products or services, clear contracts can reduce that pressure by setting expectations upfront (like payment terms, scope, and limitations of liability).
Depending on your business model, that might include a services agreement, website terms, or tailored business terms.
Employment Contracts (If You’re Hiring As You Grow)
When you hire staff, the business takes on legal obligations (such as under employment laws and workplace safety). In some situations, individuals (like partners, directors, or managers) can also face exposure depending on what happens and their role in it.
Clear Employment Contract documentation can help set expectations around duties, pay, confidentiality, and termination, and it supports smoother management as your team grows.
Consider The “Company Alternative” Documents (If You’re Not Sure Partnerships Are Right)
If, after looking at different partnership structures, you realise you’d rather operate through a company, you’ll usually want to think about:
This approach can feel more “formal”, but it’s often the structure that scales better when you start adding people, capital, or complexity.
Key Takeaways
- Common partnership structures in Australia include general partnerships, limited partnerships, and incorporated limited partnerships, plus joint ventures which are often confused with partnerships.
- In a general partnership, partners can often be personally liable for business debts and obligations, so risk management is critical.
- A limited partnership may suit situations where you have a passive investor and an active operator, but the details matter to preserve limited liability.
- Choosing the right structure depends on your risk profile, growth plans, and how you want decision-making and exits to work.
- Regardless of the structure you choose, the right documents (especially a well-drafted Partnership Agreement) can help prevent disputes and protect the business.
