Sole proprietorship vs LLP vs Pte Ltd — Step-by-step walkthrough

Raffles Corporate Services works with a panel of corporate and employment law firms; this article is general information, not legal advice.

Choosing between a sole proprietorship vs LLP vs Pte Ltd comes down to three questions: who bears the risk, how profits are taxed, and what compliance you can stomach. Sole proprietorships are cheapest, LLPs suit professional partnerships, and the Pte Ltd wins for foreign founders, scale and tax. This walkthrough compares all three for 2026.

The three structures at a glance

A sole proprietorship is not a separate legal entity. It is you, trading under a registered business name under the Business Names Registration Act 2014. You own every asset and, critically, every liability personally. A limited liability partnership (LLP) sits in the middle: section 4(1) of the Limited Liability Partnerships Act 2005 makes the LLP a body corporate with legal personality separate from its partners, so the LLP — not the partners personally — owns its debts, while profits flow through to partners and are taxed in their hands. A private limited company (Pte Ltd) is a full company under the Companies Act 1967: a separate legal person, shares that can be sold or issued to investors, limited liability for shareholders, and its own corporate tax bill. All three are registered with the Accounting and Corporate Regulatory Authority (ACRA).

Who each structure is for

  • Sole proprietorship: Singapore citizens, PRs or eligible pass holders running low-risk, low-revenue local trades — a tuition service, a stall, a freelance practice. Foreigners residing overseas can technically register one only by appointing a local authorised representative, but in practice almost no bank or counterparty supports it; foreign founders should not start here.
  • LLP: two or more professionals — accountants, surveyors, consultants, law-adjacent practices — who want liability protection from each other’s negligence while keeping pass-through taxation and light governance.
  • Pte Ltd: anyone building a business with employees, premises, investors or cross-border customers — and effectively the only sensible choice for foreign founders, because work passes, corporate banking and investor money all assume a company. For the fuller treatment of trade-offs, see our earlier reference on sole proprietorship vs LLP vs Pte Ltd.

Liability: the decisive difference

In a sole proprietorship, business creditors can pursue your house, savings and car; there is no shield at all. In an LLP, partners are generally liable only to the extent of the LLP’s assets, although a partner remains personally liable for their own wrongful act or omission — the shield protects you from your partner’s negligence, not your own. In a Pte Ltd, shareholders’ exposure stops at their paid-up capital, and directors are protected provided they comply with their statutory duties; section 157A(1) of the Companies Act 1967 places the management of the company’s business in the hands of the directors, who owe corresponding duties of honesty and diligence. If your business can be sued, hold stock, sign leases or owe suppliers meaningful sums, the limited liability structures earn their keep quickly.

Tax: pass-through vs the 17% corporate rate

Sole proprietorship and LLP profits are taxed as the owner’s or partners’ personal income at progressive resident rates of 0%–24%. That is efficient at low profits: at S$60,000 of profit, personal tax is roughly S$1,950. It becomes painful at scale: at S$300,000 of profit, a sole proprietor pays about S$44,550, while a Pte Ltd pays corporate tax at 17% with exemptions. A qualifying new company enjoys the start-up exemption — 75% off the first S$100,000 of chargeable income and 50% off the next S$100,000 for the first three years of assessment — bringing tax on S$200,000 to roughly S$21,250, and companies also access incentives unavailable to pass-through structures, such as the 400% deductions under the Enterprise Innovation Scheme. Dividends are tax-free in shareholders’ hands under the one-tier system. The crossover point at which the Pte Ltd beats pass-through taxation typically arrives around S$150,000–S$200,000 of annual profit, sooner if profits are retained for growth. Current rates and exemption details are published by the Inland Revenue Authority of Singapore (IRAS). All three structures must register for GST once taxable turnover exceeds S$1 million.

Cost and compliance compared (2026 numbers)

  • Sole proprietorship: S$15 name application + S$100 registration, renewable annually (S$30/year). No audit, no annual return; you file business income in your personal tax return. Registration under the Business Names Registration Act 2014 is mandatory before trading — section 5 of that Act requires a person carrying on business under a business name to be registered.
  • LLP: S$15 name + S$100 registration, one-time. No audit and no public accounts, but the LLP must keep proper accounting records and file an annual declaration of solvency or insolvency. Budget S$600–S$1,500 per year for bookkeeping and the declaration.
  • Pte Ltd: S$15 name + S$300 incorporation. At least one ordinarily resident director under section 145(1) of the Companies Act 1967, a company secretary within 6 months, an annual return within 7 months of financial year end, and accounts prepared under the Singapore Financial Reporting Standards. Small companies (two of: revenue ≤ S$10 million, assets ≤ S$10 million, ≤ 50 employees) are audit-exempt. Realistic running cost: S$1,500–S$4,500 per year including secretary, registered address and accounts.

Timeline is similar for all three: name approval is usually instant, and registration completes in 1–3 working days.

Step-by-step: choosing and registering

  1. Map your risk. List what could go wrong — defective work, unpaid suppliers, staff claims. If any failure could exceed what you can personally absorb, eliminate the sole proprietorship.
  2. Project three years of profit. Below about S$100,000 a year and purely local? Pass-through tax may win. Above S$150,000–S$200,000 or reinvesting heavily? The Pte Ltd’s 17% rate and exemptions win.
  3. Check your eligibility. Foreign founders living abroad need a structure that accommodates a local officer: the Pte Ltd needs one resident director, and an LLP needs a local manager. Professional nominee services cost S$1,500–S$3,000 per year. If you plan to relocate and run the business yourself, factor in an Employment Pass — qualifying salary at least S$5,600 per month and rising; see the Ministry of Manpower (MOM) and this planning note on work pass salary thresholds rising in January 2027.
  4. Reserve the name (S$15). Same process for all three structures; the name holds for 120 days.
  5. Register through BizFile+ or a filing agent. Locals can self-file with Singpass; foreigners must use a registered filing agent who performs KYC on all owners.
  6. Complete post-registration steps. Open the bank account, register for GST if applicable, take up the licences your SSIC activity requires, and for a Pte Ltd appoint the secretary and set the compliance calendar.
  7. Review annually. Many businesses outgrow their structure; converting a sole proprietorship or LLP into a Pte Ltd is common but requires novating contracts, re-papering bank facilities and transferring licences — cleaner to start with the right vehicle than to convert under pressure.

Side-by-side comparison

The practical differences condensed:

  • Legal personality: sole proprietorship — none, the owner is the business; LLP — separate body corporate under section 4(1) of the Limited Liability Partnerships Act 2005; Pte Ltd — separate company under the Companies Act 1967.
  • Owner liability: sole proprietorship — unlimited and personal; LLP — limited, except for a partner’s own wrongful acts; Pte Ltd — limited to paid-up capital.
  • Tax treatment: sole proprietorship and LLP — owner’s personal rates of 0%–24%; Pte Ltd — 17% corporate rate with start-up and partial exemptions, tax-free dividends.
  • Set-up cost: S$115 / S$115 / S$315 in government fees respectively.
  • Annual upkeep: S$30 renewal for the sole proprietorship; bookkeeping plus an annual declaration for the LLP; secretary, annual return, accounts and tax filings for the Pte Ltd, typically S$1,500–S$4,500.
  • Raising money: sole proprietorship — personal borrowing only; LLP — partner contributions; Pte Ltd — share issues to investors, convertible notes, employee share options.
  • Continuity and exit: a sole proprietorship dies with its owner and cannot be sold as an entity; an LLP survives partner changes; a Pte Ltd offers perpetual succession and clean share sales.
  • Perception: government tenders, enterprise customers and landlords routinely require or strongly prefer a Pte Ltd counterparty.

Hiring and work passes by structure

If the business will employ anyone, structure choice has immigration consequences. All three structures can hire local employees and make CPF contributions once registered. Work pass sponsorship is where they diverge in practice: Employment Pass and S Pass applications are assessed on the strength of the sponsoring entity, and the Ministry of Manpower expects a credible employer with real capital, premises and payroll. A Pte Ltd with paid-up capital and accounts clears that bar far more easily than a sole proprietorship, and sole proprietors face an additional structural oddity — the owner cannot meaningfully employ themselves, so a foreigner cannot use their own sole proprietorship as a route to residency. Quota-controlled passes also count against the entity’s local workforce, which is simpler to evidence inside a company running formal payroll. Founders planning to build a team of any size should treat the Pte Ltd as the default and budget pass costs — S$105 per EP application and S$225 on issuance — into the first-year plan.

Common mistakes

  • Choosing a sole proprietorship purely for the S$115 set-up cost, then signing a S$120,000 office lease personally.
  • Assuming an LLP shields you from your own professional negligence — it does not; it shields you from your partners’.
  • Foreign founders trying to register a sole proprietorship from abroad instead of incorporating a Pte Ltd, then discovering no bank will onboard them.
  • Ignoring the tax crossover and paying 22%–24% marginal personal rates on profits a company would shelter at an effective rate near 10%.
  • Forgetting the LLP’s annual declaration of solvency, which attracts penalties just like a missed company annual return.
  • Splitting one business across several sole proprietorships to dodge GST registration — IRAS aggregates closely connected businesses.

Converting later: what an upgrade really involves

Plenty of businesses start as a sole proprietorship and “convert” to a Pte Ltd once revenue, risk or hiring justifies it. Be clear-eyed about what conversion means: there is no statutory transformation. You incorporate a fresh company, then transfer the business into it — assigning or novating every customer and supplier contract, transferring assets at properly documented values, reapplying for licences in the company’s name, opening new bank accounts, and notifying CPF, IRAS and your insurers. The sole proprietorship is then ceased on BizFile+. The process typically takes 4–8 weeks of administrative work and S$1,000–S$3,000 in professional fees, and anything missed (a licence, a lease consent clause, a GST registration) follows you around afterwards. ACRA does offer a streamlined conversion path for ordinary partnerships and sole proprietorships moving to LLP form, but moving to a company is always a transfer-of-business exercise. The practical lesson sits in the step-by-step above: if you can already see employees, premises or investors within two years, incorporate the Pte Ltd at the outset and skip the conversion entirely.

FAQs

Which is cheapest to run: sole proprietorship vs LLP vs Pte Ltd?
The sole proprietorship, at about S$30 a year in renewal fees plus minimal bookkeeping. The LLP is next; the Pte Ltd costs S$1,500–S$4,500 a year to maintain but buys liability protection and lower tax at scale.

Can a foreigner register a sole proprietorship in Singapore?
Only with a locally resident authorised representative, and banks rarely support the arrangement. Foreign founders almost always incorporate a Pte Ltd instead.

When does a Pte Ltd become more tax-efficient than a sole proprietorship?
Typically once annual profits pass roughly S$150,000–S$200,000, or earlier if you retain profits in the business, because the corporate rate with exemptions undercuts personal marginal rates of 18%–24%.

Can I convert my sole proprietorship into a Pte Ltd later?
Yes. You incorporate a new company, transfer the assets and contracts, and cease the sole proprietorship. It works, but expect friction with licences, bank accounts and existing contracts.

Does an LLP pay corporate tax?
No. The LLP itself is tax-transparent: individual partners pay personal income tax on their profit share, and corporate partners pay corporate tax on theirs.
