An incorporated limited partnership (ILP) is a partnership that has been given its own legal identity by being registered under state or territory partnership legislation. It lets investors put capital into a business with their liability capped at what they contribute, while one or more managers carry unlimited liability for the partnership's debts. In Australia the structure is used almost exclusively as a vehicle for venture capital and private equity funds.
This article explains how the structure actually operates: the two classes of partner and the tension between them, how an ILP is formed and registered, who is liable for what, the strict rules about who can manage the business, and the federal registration and tax regime that makes the structure worthwhile. It closes with the points where the structure most often comes unstuck, and where a lawyer earns their keep.
The two classes of partner
An ILP always has two classes of partner, and the division between them is the whole point of the structure.
- General partners: manage the business, and their liability for the partnership's debts is not capped. Under s 9 of the Partnership Act 1892 (NSW) (legislation.nsw.gov.au), each general partner is liable jointly with the ILP for debts and obligations incurred while they were a general partner.
- Limited partners: contribute capital but stay out of management. Their liability is limited to the capital they have agreed to contribute. They are the investors.
Every ILP must have at least one of each (s 51), and in NSW a corporation can be a general partner or a limited partner, which is how most venture capital funds are structured in practice. The Act also caps the numbers: an ILP can have any number of limited partners, but no more than 20 general partners in NSW (s 52). Other states and territories have equivalent regimes in their own partnership legislation.
The competing tension should be obvious. The general partners carry the risk, so they expect to control the business. The limited partners provide the money, and their reward is limited liability. The law polices the boundary between the two roles closely, and most of the rules in this article are about what happens when someone tries to have both.
How an ILP comes into existence
An ILP does not exist until it is registered. Under s 50A of the Partnership Act 1892 (NSW), a limited partnership is formed by and on registration, and an ILP is formed by and on registration as an incorporated limited partnership. There is no way to "incorporate" an existing ordinary partnership without going through this step, although the Act does allow a registered limited partnership to convert into an ILP (s 55(2B)).
The registration process is a state matter. In NSW, an application is lodged with the Registrar, who is the Commissioner for Fair Trading (s 49). The application is a statement signed by each proposed partner, and it must state whether the partnership is to be registered as a limited partnership or an ILP, give the firm name and the address of the partnership's registered office in NSW, and set out particulars of the proposed partners (s 54). The Registrar must register the partnership once the application is in order, but cannot register a firm name that would not be eligible for registration as a business name under the Business Names Registration Act 2011 (Cth) (s 55(2)).
Registration is not a passive formality. The recorded particulars become the partnership's public identity, and ongoing obligations attach to it. In NSW, any document issued on behalf of an ILP in connection with its business must contain the words "An Incorporated Limited Partnership" (or the abbreviation "L.P." or "LP") at the end of the firm name, and a person who issues a document in contravention commits an offence (s 75). So the common shorthand that ILPs "must use ILP in their name" understates the rule: the requirement is that the entity identify itself correctly on its documents, in legible letters.
Who is liable for what
The liability rules are where the structure earns its keep, and where careless behaviour costs money.
A general partner is personally on the hook. Under s 9(2) of the Partnership Act 1892 (NSW), a general partner is liable jointly with the ILP for all debts and obligations of the partnership incurred while they were a general partner, and an individual general partner's estate remains severally liable after their death. There is no corporate veil for the managers.
A limited partner's exposure is capped at their capital commitment, but only while they stay within the role the law assigns them. The critical provision is s 67A(1): a limited partner in an ILP must not take part in the management of the business of the partnership. The consequences are set out in s 67A(2): if a limited partner's wrongful act or omission in taking part in management causes loss or injury to someone outside the partnership, and that person had reasonable grounds to believe the limited partner was a general partner, the limited partner is liable to the same extent as if they were a general partner. Note the shape of this rule: it is a third-party protection, triggered by what outsiders could reasonably have believed, not a blanket forfeiture of limited liability for everything the partnership owes.
The safe harbours in s 67A(3) are important for investors who want to be involved without crossing the line. A limited partner is not taken to be managing the business merely because they are an employee or officer of a general partner, give professional advice to the partnership, give a guarantee or indemnity for its liabilities, act to enforce their own rights as a limited partner, inspect the books or consult with other partners where the agreement allows it, or take part in specified committee and governance functions to the extent the partnership agreement authorises them. Section 67A(5) makes the position clear: the provision may not be varied by the partnership agreement, so there is no contractual workaround to let a limited partner manage and keep the cap on liability.
The management line: what limited partners cannot do
The agency rules reinforce the same boundary. Under s 53C(1) of the Partnership Act 1892 (NSW), a limited partner is not an agent of, nor a fiduciary for, a general partner, another limited partner or the partnership itself, and the acts of a limited partner do not bind a general partner, another limited partner or the partnership, unless the partnership agreement provides otherwise. The effect is that an over-eager limited partner who strikes a deal on the partnership's behalf cannot saddle the other partners with it, but equally cannot claim authority to act for the partnership.
This is a real difference from an ordinary partnership, where every partner is an agent of the firm and binds the others in the ordinary course of business. In an ILP, the authority to bind the entity sits with the general partners, and the partnership agreement is the document that allocates it. That is why the partnership agreement matters so much in this structure: it is the contract that defines each partner's rights and duties, and it fills the gaps the statute leaves open. The Act repeatedly points back to it, for example in the safe-harbour activities a limited partner may carry out only "to the extent authorised by the partnership agreement", and s 53A(2), which allows the agreement to limit the ILP's powers.
For a fund manager reading this, the practical takeaway is that the partnership agreement is the operating manual for the whole structure. It should state in detail what the general partners may do without reference to the limited partners, what requires investor approval, and what the limited partners are permitted to do without being treated as managers.
A separate legal person
Unlike an ordinary partnership, which has no existence distinct from its partners, an ILP is a legal entity in its own right. Under s 53 of the Partnership Act 1892 (NSW), an ILP is a body corporate with legal personality separate from that of its partners, has perpetual succession, may have a common seal, and may sue and be sued in its firm name. Section 53A gives it the legal capacity and powers of an individual as well as the powers of a body corporate, including the power to hold property, enter contracts and participate in other entities.
The practical consequences are significant. Property can be held in the partnership's own name, contracts run in its name, and the partners can change without dissolving the entity. The entity continues regardless of who the partners are at any given moment. This is the feature that makes long-lived investment funds workable, because investors can enter and exit without the fund having to be wound up and re-formed each time.
The venture capital layer: federal registration and tax
The state ILP is only half the story. The reason the structure is attractive for venture capital is the federal regime built on top of it, and it is worth understanding how the two layers interact.
The Venture Capital Act 2002 (Cth) (legislation.gov.au) lets Industry Innovation and Science Australia register a limited partnership as one of three types of venture capital vehicle: a venture capital limited partnership (VCLP), an early stage venture capital limited partnership (ESVCLP), or an Australian venture capital fund of funds (AFOF). Registration is a prerequisite for the tax concessions, which are set out in the income tax legislation:
- the capital gains tax exemption for venture capital investments under Subdivision 118-F of the Income Tax Assessment Act 1997 (Cth);
- the income tax exemption for investments by an ESVCLP under s 51-52 of that Act; and
- "flow-through" treatment of the partnership's income under Division 5 of Part III of the Income Tax Assessment Act 1936 (Cth), so the partnership itself is not taxed and each partner is taxed on their share (legislation.gov.au).
The four labels commonly used in the market are the three registrable types plus a fourth that is defined in the tax law. A VCLP is a general venture capital fund that invests directly in eligible companies. An ESVCLP targets early stage and small companies; broadly, the eligible companies must have total assets of no more than $50 million before the investment, subject to detailed conditions in the income tax law. An AFOF is a fund of funds, which invests through VCLPs and ESVCLPs rather than directly in companies. The fourth category, a venture capital management partnership (VCMP), is defined in s 94D(3) of the Income Tax Assessment Act 1936 (Cth) as a limited partnership that acts as general partner of one or more VCLPs, ESVCLPs or AFOFs and carries on only activities related to that role. The same provision confirms that VCLPs, ESVCLPs, AFOFs and VCMPs are taxed as ordinary partnerships under Division 5, which is the flow-through treatment that makes the structure tax-transparent.
Registration is not a rubber stamp. For a VCLP, s 9-1 of the Venture Capital Act 2002 (Cth) requires, among other things, that the partnership be established under Australian law (or the law of a country with which Australia has a double tax agreement), that the general partners be residents of such a country, that the partnership agreement provide for the partnership to exist for at least 5 and no more than 15 years, that committed capital be at least $10 million, and that every investment be an "eligible venture capital investment" as defined in the tax law. The registration itself is applied for by a general partner, and once registered, the partnership must file annual returns with Industry Innovation and Science Australia (s 15-1). Registration can be revoked if the partnership ceases to meet the requirements, including the investment requirements (Division 17), and losing registration means losing the tax treatment.
Where the structure comes unstuck
The failure modes of an ILP tend to cluster around a few predictable points.
The most common is the limited partner who drifts into management. An investor who is used to having a say in a private company may find the hands-off role of a limited partner frustrating, and the boundary in s 67A is technical. The safe harbours cover a lot of ordinary investor activity, but they are not a licence to run the business, and s 67A(5) means the agreement cannot save someone who does.
The second is documentation. The requirement to identify the entity correctly on documents is easy to miss, and it carries an offence in NSW. Anyone issuing invoices, contracts or letters on behalf of an ILP without the required suffix is putting the partners at risk of penalty, and sloppy identification also blurs the line the third-party liability rule in s 67A(2) depends on. If outsiders cannot tell who they are dealing with, the reasonable-belief test can go against the partnership.
The third is the federal conditions. The tax treatment is conditional, not automatic. A fund whose investments drift outside the eligible categories, whose general partners change residency, or whose committed capital or term falls outside the statutory ranges, risks revocation of registration and the tax consequences that follow. These are continuing obligations, not a once-off application.
The fourth is using the structure for the wrong purpose. The ILP's advantages, separate legal personality, capped liability for investors and tax-transparent treatment, are built around the venture capital regime. An ordinary trading business with no venture capital angle gets the registration overhead, the 20 general partner cap and the management restrictions without most of the tax upside, and a company or trust is usually a better fit.
When to bring in a lawyer
Setting up an ILP involves two regulators, two bodies of legislation and a tax regime that only works if the details are right, so this is a structure to build with professional help rather than after it.
A lawyer's role starts before registration. The partnership agreement is the document that allocates management authority, and it needs to be drafted so that the limited partners' safe-harbour activities are expressly authorised where they are wanted, and clearly excluded where they are not. The same advice should cover the state registration itself, the choice of firm name, and the corporate partner structure that most funds use.
The second stage is the federal registration. An application to register a VCLP, ESVCLP or AFOF needs to satisfy the statutory requirements at the date of application and on an ongoing basis, and a lawyer will work through those conditions with the fund's accountant before the application is lodged. Tax advice is essential here because the concessions, the flow-through treatment, the CGT exemption and the ESVCLP income exemption, sit in the income tax legislation and are fact-sensitive.
The third stage is ongoing. Partner changes, cross-border investors, new investment types and changes to the general partner all interact with the state register and the federal registration, and a lawyer can keep the structure compliant and flag problems before registration is at risk. For an investor being invited into a fund, a lawyer can also review the partnership agreement and explain exactly what the management restrictions mean for them in practice.
The line between investing and managing
The entire structure turns on one decision: which side of the line each partner sits on. General partners carry unlimited liability and control the business. Limited partners contribute capital, stay out of management, and keep their liability capped. The moment an investor starts making business decisions on the partnership's behalf, they start looking like a general partner to the outside world, and s 67A(2) can make them liable as one.
That is the question worth answering before committing to an ILP: as a potential limited partner, can you genuinely stay out of management, and as a potential general partner, are you prepared to carry the unlimited liability that goes with control? If the answer to either is unclear, structure the roles on paper before registration, not after. Getting the classification right at the start, with a properly drafted partnership agreement and correct state and federal registration, is what makes the ILP deliver its one real benefit, limited liability for investors and tax-transparent venture capital, without the personal exposure that follows a blurred line.
