Singapore has five main business structures: sole proprietorship, partnership, limited partnership (LP), limited liability partnership (LLP), and company. The right choice depends mainly on who owns the business, whether you want a separate legal entity, how much personal liability you are prepared to take on, and how you expect the business to grow.
For many small businesses, the practical comparison comes down to a sole proprietorship, LLP or private limited company. A sole proprietorship is simple but does not separate the owner from the business. An LLP and a company are separate legal entities, but they have different ownership, tax and compliance structures.
Singapore business structures compared
Choosing a structure is more than choosing a registration form. It affects liability, continuity, tax treatment, ownership changes and the amount of ongoing administration. ACRA's current business-structure guidance recognises the five structures below.
| Structure | Owners | Separate legal entity? | Personal liability | Tax basis | Typical ongoing administration |
|---|---|---|---|---|---|
| Sole proprietorship | 1 owner | No | Unlimited. The owner is responsible for the business's debts and losses. | At owner level | Business registration must be renewed every 1 or 3 years; business particulars must be kept current. |
| Partnership | Usually 2 to 20 partners; professional partnerships can have more | No | Unlimited. Partners can be personally responsible for partnership debts. | At partner level | Business registration renewal and updates to partners/business particulars. |
| Limited partnership (LP) | At least 1 general partner and 1 limited partner; no maximum | No | General partner has unlimited liability. Limited partner's liability is capped at the agreed contribution if the limited partner does not take part in management. | At partner level | Registration renewal, partner changes and maintaining the required local manager where applicable. |
| Limited liability partnership (LLP) | At least 2 partners; no maximum | Yes | Partners are not personally liable for business debts caused by other partners, but remain liable for their own wrongful acts. | At partner level | Local manager, accounting records, Register of Registrable Controllers unless exempt, and annual declarations. |
| Company, such as a Pte Ltd | At least 1 shareholder; shareholder limits depend on company type | Yes | Shareholders generally have limited liability. | At company level | Directors and company secretary, company registers, accounting and financial reporting, Annual Returns and corporate tax filings. |
Sole proprietorship: simple, but the owner and business are legally the same
A sole proprietorship has one owner and is not a separate legal entity. That makes the structure straightforward, but it also means the owner takes unlimited personal liability for the business's debts and losses.
For an individual owner, the business profit forms part of the owner's personal income rather than being taxed as the profit of a separate company. The registration is also not perpetual: it is registered for one or three years and must be renewed if the business continues.
A sole proprietorship can make sense for a small one-owner activity where simplicity matters and the commercial risk is limited. Once a business starts taking on substantial contractual risk, employees, investors or significant assets, the lack of legal separation becomes more important.
Partnership: shared ownership with shared personal liability
A general partnership is run by at least two partners and is not a separate legal entity. A normal partnership can have up to 20 partners, while qualifying professional partnerships can have more.
The key trade-off is liability. Partners have unlimited liability and can be personally responsible for partnership debts, including liabilities arising from the actions of other partners. Profits are allocated to the partners and taxed at the relevant partner level.
This can suit owners who deliberately want a traditional partnership arrangement, but it provides less personal-asset protection than an LLP or company.
Limited partnership: different roles for general and limited partners
A limited partnership must have at least one general partner and one limited partner. It is not a separate legal entity.
The general partner runs the business and has unlimited liability. A limited partner's liability is capped at the contribution agreed with the LP, but the limited partner must not take part in management. If a limited partner participates in management, ACRA states that the partner will be treated as a general partner.
LPs are therefore more specialised than the other structures. They are useful where the owners intentionally want different managing and limited-investor roles, rather than simply wanting a two-person business.
Limited liability partnership: separate legal identity with partnership-style ownership
An LLP is a separate legal entity with at least two partners and no maximum number of partners. It can own property, enter contracts, sue and be sued in its own name.
Partners are generally protected from debts caused by other partners, although each partner remains responsible for liabilities arising from that partner's own wrongful acts. The LLP must also have at least one manager who meets Singapore's local-residency requirements.
Compared with a general partnership, the LLP provides stronger separation between the business and its partners. Compared with a company, it keeps partnership-style tax treatment and ownership rather than using shares and corporate income tax.
If an LLP is the structure you are considering, our Singapore LLP formation service explains the registration support we provide.
Company: separate ownership, limited liability and a more formal compliance structure
A company is a separate legal entity owned by shareholders and managed by directors. For most owner-managed businesses choosing the company route, the relevant structure is a private company limited by shares, commonly shown as “Pte Ltd”.
Shareholders generally have limited liability, and the company continues to exist independently of changes in shareholders. That structure is useful where the business needs a clearer ownership framework, plans to bring in investors, wants shares to be transferable, or expects to grow beyond a small owner-operated activity.
The trade-off is more administration. A company has its own corporate tax obligations and statutory requirements involving directors, a company secretary, company registers, accounting and financial reporting, Annual Returns and other filings that apply to its circumstances.

Which business structure should you choose?
There is no single structure that is best for every business. The useful question is what you need the structure to do for you.
You are starting alone and want the simplest structure
A sole proprietorship can be suitable where the business is small, has one owner and carries limited commercial risk. The main downside is unlimited personal liability.
You have two or more owners and want legal separation
An LLP is often worth considering where the owners want partnership-style ownership but do not want the business to be legally identical to the partners.
You expect to raise capital, add shareholders or scale
A private limited company usually provides the clearest structure for shares, ownership changes, investment and long-term continuity, although it comes with more formal compliance.
You want a traditional partnership arrangement
A general partnership is available, but all partners should understand the unlimited-liability position before choosing it over an LLP.
Five questions worth answering before you register
- Will there be one owner or several?
- Do you want the business to be a separate legal entity?
- How much personal liability are the owners prepared to accept?
- Will you need investors, transferable ownership or a structure that can continue independently of the founders?
- Are you comfortable with the ongoing compliance that comes with the structure?
Once those answers are clear, the choice between a sole proprietorship, partnership, LLP and company is usually much easier.
What if the owners are foreigners?
Foreign ownership is possible, but the registration and local-residency requirements depend on the structure. For example, ACRA requires foreigners living overseas who register a sole proprietorship or partnership to engage a registered Corporate Service Provider and appoint an authorised representative who meets the local-residency requirements. An LLP must have at least one locally resident manager. A Singapore company has its own director and officer requirements.
If you are registering from overseas, check the structure-specific requirements before treating ownership and the right to work in Singapore as the same issue. Business ownership does not by itself give a person immigration or work-authorisation rights.
ACRA's current registration guides set out the process for each structure.
