Choosing the Right Business Structure in Singapore: Sole Proprietorship vs Private Limited vs LLP

Last Updated: June 2026

For most people starting a real business in Singapore, the private limited company (Pte Ltd) is the right structure. It gives you limited liability, a flat 17% corporate tax rate with generous start-up exemptions, and the credibility banks, investors, and large clients expect. A sole proprietorship is cheaper and faster to register, but you and the business are legally the same person, so your personal savings and other assets are exposed if the business is sued or cannot pay a debt.

The short version: choose a sole proprietorship only for a very small, low-risk side venture. Choose a Pte Ltd the moment you take on real customers, hire staff, sign contracts, or want to grow. The deciding factors are liability, tax, cost, and credibility, and they almost always point the same way once a business becomes serious.

Key Takeaways

• A sole proprietorship is not a separate legal entity, so the owner carries unlimited personal liability for every business debt.
• A Pte Ltd is a separate legal entity with limited liability, taxed at 17% with start-up and partial exemptions, and is the structure most Singapore SMEs choose.
• Sole proprietors are taxed at personal income tax rates, while a Pte Ltd is taxed as a company on its own profits.
• A sole proprietor cannot pay himself a CPF salary, because the owner and the business are one and the same.
• An LLP sits in the middle: a separate legal entity that shields a partner from another partner’s wrongful acts, but still taxed at each partner’s personal rate.
• Converting a sole proprietorship into a Pte Ltd is a normal, common step as a business grows.

What are the main business structures in Singapore?

When you register a business with the Accounting and Corporate Regulatory Authority (ACRA), you are choosing among four common options: a sole proprietorship, a general partnership, a limited liability partnership (LLP), and a private limited company. They differ mainly in three things: whether the business is a separate legal entity from you, whether your liability is limited, and how the profits are taxed.

The chart below compares the three structures most small businesses weigh up, so you can see the trade-offs side by side before reading the detail.

Sole proprietorship: simple but risky

A sole proprietorship is the simplest structure. One owner, low cost, minimal paperwork. The catch is that it is not a separate legal entity. In the eyes of the law, you and the business are the same person.

That single fact creates the biggest disadvantage: unlimited personal liability. If the business owes money or is sued, creditors can come after your personal assets, including your savings and, in serious cases, your property. There is no legal wall between business risk and personal wealth.

A sole proprietorship can still suit a very small, low-risk venture: a part-time tutor, a small online shop, a freelance service with little chance of being sued. For anything with real contracts, staff, or borrowing, the risk usually outweighs the savings.

The common disadvantages of a sole proprietorship are:

• Unlimited personal liability for all business debts and claims.
• Profits are taxed at your personal income tax rates, which rise as you earn more.
• Limited credibility with banks, investors, and larger corporate clients.
• Harder to raise capital, since you cannot issue shares.
• The business does not continue automatically if the owner stops or passes away.

Partnership and LLP: sharing the load

If two or more people run a business together, the basic option is a general partnership, which allows 2 to 20 partners. Like a sole proprietorship, a general partnership gives every partner unlimited liability, and worse, each partner can be held responsible for debts the others run up.

A limited liability partnership (LLP), created under the Limited Liability Partnership Act 2005, fixes much of that. An LLP is a separate legal entity, so the partnership itself owns its debts, and a partner is not personally liable for another partner’s wrongful acts or negligence. Profits, however, are still taxed at each partner’s personal income tax rate, not the corporate rate.

An LLP suits professional partners (for example, a small consultancy) who want a shield from each other’s mistakes but do not need to issue shares. If raising outside capital matters, a Pte Ltd is usually the better fit.

The private limited company: why most SMEs choose it

A private limited company is incorporated under the Companies Act 1967 and is a separate legal entity from its owners. It can have up to 50 shareholders. This separation is the whole point: the company signs contracts, owns assets, and owes debts in its own name.

The main reasons Singapore SMEs default to a Pte Ltd are:

• Limited liability: shareholders generally risk only the capital they put in, not their personal assets.
• Lower tax on profits: a flat 17% corporate rate, plus start-up and partial exemptions that reduce the bill in the early years.
• Credibility: banks, government tenders, and large clients take a Pte Ltd more seriously.
• Scalability: you can issue shares to bring in co-founders, investors, or an employee option pool.

Because shares are involved, a Pte Ltd needs a little more planning. It helps to get the shareholding structure right early, decide your paid-up capital, and put a sensible company constitution in place. Some founders even start from a ready-made shelf company, though most incorporate fresh.

How are the structures taxed?

Tax is where the gap between a sole proprietorship and a Pte Ltd becomes obvious as profits grow.

A sole proprietor reports business profit as personal income and pays personal income tax on it. Those rates are progressive, so the more you earn, the higher the marginal rate. An LLP works the same way: each partner is taxed on their share at personal rates.

A Pte Ltd is taxed as a company on its own profits at the flat 17% corporate income tax rate, before exemptions. Start-up and partial tax exemptions then cut the effective rate further in the first years, which is why retained profits are taxed more lightly inside a company than in a sole proprietor’s hands. To plan how money leaves the company, see our guide on director salary vs dividends.

Can a sole proprietor pay himself a salary?

No. A sole proprietor cannot pay himself a salary in the way an employee or a company director is paid, and cannot make CPF contributions on a salary, because the owner and the business are one entity. Money you take out is a drawing of profit, not a deductible wage, so it does not reduce the business’s taxable income.

A Pte Ltd is different. As a director and employee of your own company, you can draw a salary (with CPF) and dividends, and the salary is a deductible expense for the company. This flexibility is a real planning advantage that a sole proprietorship simply cannot offer.

How much does each structure cost?

Cost is the main reason people start with a sole proprietorship, and the gap is smaller than most expect.

• Sole proprietorship or partnership name: roughly S$15 to reserve the name plus S$100 per year for registration (please verify the current fee on the ACRA website, as fees change).
• Company incorporation: roughly S$315 in ACRA fees (about S$15 for the name and S$300 for registration), again subject to change.
• Renewal: a sole proprietorship registration is renewed every 1 or 3 years, while a company does not re-register but must keep up annual filings.

The headline registration cost of a company is modest. The real ongoing difference is compliance: a Pte Ltd must keep proper accounts and meet annual filings, which our overview of accounting and compliance in Singapore explains. If you have heard about very cheap setups, our piece on registering a company from S$1 in capital separates the marketing from the real numbers.

When should you convert a sole proprietorship to a Pte Ltd?

Converting is common and sensible as a business grows. Consider switching to a Pte Ltd when:

• Your liability exposure rises, for example you sign larger contracts, take on debt, or hire staff.
• Profits are high enough that the 17% corporate rate plus exemptions beats your personal tax rate, especially if you reinvest retained profit.
• You want to raise capital, bring in a co-founder, or set up an option pool.
• Clients, banks, or tenders expect to deal with an incorporated company.
• You plan to add structure later, such as a holding company, or you need to register for GST once you cross the S$1 million GST threshold.

Foreign founders have an extra layer to consider, which our guide on opening a business in Singapore as a foreigner covers. And if you are wondering where the line sits between a legitimate dormant company and something dubious, see our explainer on whether a shell company is illegal in Singapore.

Frequently Asked Questions

What are the 5 disadvantages of a sole proprietorship?

The five main drawbacks are unlimited personal liability for business debts, profits taxed at higher personal income tax rates, limited credibility with banks and large clients, difficulty raising capital because you cannot issue shares, and no automatic continuity if the owner stops or passes away. The liability issue is the most serious, since your personal assets are exposed.

Is a sole proprietorship taxed differently from a private limited company?

Yes. A sole proprietorship is not a separate entity, so its profit is taxed as the owner’s personal income at progressive personal rates. A private limited company is a separate entity taxed at the flat 17% corporate rate, with start-up and partial exemptions that lower the effective rate in the early years.

Can a sole proprietor pay himself a salary in Singapore?

No. Because the owner and the business are one entity, money taken out is a drawing of profit, not a salary, and no CPF is paid on it. It is also not a deductible expense. A Pte Ltd director, by contrast, can draw a CPF-bearing salary plus dividends, and the salary is deductible for the company.

Which business structure is best for a small business in Singapore?

For most genuine small businesses, a private limited company is best because of limited liability, lower tax on retained profits, and credibility. A sole proprietorship only makes sense for a very small, low-risk venture where simplicity and cost matter more than protection.

Can I convert my sole proprietorship to a Pte Ltd?

Yes, and it is a common step as a business grows. Founders usually convert to gain limited liability, access lower corporate tax on retained profits, and improve credibility with banks, investors, and clients. The process involves incorporating a new company and transferring the business across.

What is the difference between an LLP and a Pte Ltd?

Both are separate legal entities, but an LLP is taxed at each partner’s personal income tax rate, while a Pte Ltd is taxed at the corporate rate with exemptions. An LLP suits professional partners who want protection from each other’s mistakes, whereas a Pte Ltd suits businesses that want to issue shares and raise capital.

Not sure which structure fits your plans?

Choosing between a sole proprietorship, an LLP, and a Pte Ltd is easier once you weigh your real liability, tax, and growth picture rather than just the setup fee.
