The core difference: a sole proprietorship makes you personally liable for every business debt, while a Pte Ltd is a separate legal entity that shields your own savings and pays a lower corporate tax rate. For most students and first-time founders in Singapore, a sole proprietorship is cheaper and faster to start, but a Pte Ltd protects you once real money and real risk are on the line.
Below is a plain comparison of the two structures across the four things that actually decide it: who is liable, how you are taxed, what it costs, and how much admin you sign up for. Figures are stated as of June 2026 and linked to the official pages so you can check them yourself.
What each structure actually is
A sole proprietorship is a business owned by one person and registered with the Accounting and Corporate Regulatory Authority (ACRA). It is not a separate legal entity. In the eyes of the law, you and the business are the same person, so the business does not own anything on its own, cannot sue in its own name, and dies with you. Registration is quick and can be done through the GoBusiness portal, usually within a day once your name is approved.
A private limited company, written as Pte Ltd, is a separate legal entity from its owners. It has its own shareholders and directors, holds its own bank account and contracts, and keeps running even if a shareholder leaves or passes away. You register it as a local company with ACRA, and it comes with more paperwork in exchange for stronger protection and a more serious profile. ACRA sets out the full setup steps on its local company guide.
Liability: whose money is on the line
This is the real dividing line, and it matters more than tax for most people. In a sole proprietorship there is no wall between your business and your personal finances. If the business owes a supplier $40,000 and cannot pay, that supplier can chase your personal savings, and in a bad case a court can go after personal assets. A single bad contract or an unhappy client with a valid claim becomes your problem directly.
A Pte Ltd gives you limited liability. If the company fails owing money, your loss is capped at the share capital you put in, which can be as little as $1. Creditors take the company, not your flat or your salary from another job. That protection is not absolute. Banks often ask directors of young companies to sign personal guarantees on loans, which cancels the shield for that specific debt, and directors who act fraudulently or breach their legal duties can still be held personally responsible. For an ordinary trading business without personal guarantees, though, the wall holds.
How each structure is taxed
A sole proprietorship is not taxed as a business. The profit is treated as your personal income and taxed at Singapore's progressive personal income tax rates, which run from 0 percent on the first $20,000 of chargeable income up to a top rate of 24 percent as of June 2026. You file it as self-employed trade income, and because you are self-employed, MediSave contributions apply once your net trade income passes the annual threshold. IRAS explains the filing and MediSave rules for the self-employed on its self-employed and partnerships page.
A Pte Ltd pays corporate income tax at a flat headline rate of 17 percent as of June 2026, but a new company rarely pays anything close to that in its early years. Under the Start-Up Tax Exemption, a qualifying new company gets 75 percent off its first $100,000 of normal chargeable income and 50 percent off the next $100,000 for its first three years of assessment. After that, the Partial Tax Exemption still shaves a large chunk off the first $200,000 of income. IRAS lists the current rates and exemption schemes on its corporate tax exemption page. The practical takeaway: at low profits a sole proprietor often pays little or nothing because of the personal 0 percent band, while at higher profits the flat corporate rate plus exemptions usually wins.
Side-by-side comparison
| Factor | Sole proprietorship | Private limited company (Pte Ltd) |
|---|---|---|
| Legal status | Not separate from you | Separate legal entity |
| Liability | Unlimited, personal assets at risk | Limited to share capital |
| Owners | One owner only | 1 to 50 shareholders |
| How profit is taxed | Your personal income (0 to 24% as of June 2026) | Corporate rate 17% with start-up exemptions |
| Setup cost (as of June 2026) | About $115 (name $15 plus $100 for one year) | About $315 (name $15 plus $300 registration) |
| Yearly admin | Renew registration, declare income | Annual return, financial statements, AGM, secretary |
| Raising outside money | Hard, no shares to sell | Can issue shares to investors |
| Continuity | Ends with the owner | Continues past any owner |
Cost and compliance you sign up for
On price alone the sole proprietorship wins. As of June 2026 you pay a $15 name application fee and $100 to register for one year, so roughly $115 to be trading. A Pte Ltd costs a $15 name fee plus $300 registration, about $315, and that is before any help you pay for. The bigger gap is the ongoing work. A sole proprietor mostly needs to renew the registration before it lapses and declare the income at tax time.
A Pte Ltd carries a heavier load. You need at least one director who ordinarily lives in Singapore, you must appoint a company secretary within six months, and you file an annual return with ACRA plus financial statements every year and hold an annual general meeting unless you qualify for an exemption. Many founders pay a corporate services firm a few hundred dollars a year to handle this. It is manageable, but it is real work that a one-person side hustle usually does not need on day one.

Which one fits where you are now
If you are a student or fresh grad testing something small, tuition, freelance design, a modest online store, start as a sole proprietor. It is cheap, fast, and you can be earning within a week. Keep clean records of what comes in, because either way you have to report the profit to IRAS, and our guide on how to declare side income for tax in Singapore covers exactly what counts and when. If you are still deciding how to get registered in the first place, read how to register a business in Singapore as a student first.
Move to a Pte Ltd when the stakes rise: you are signing larger contracts, taking on staff, buying inventory on credit, raising money from investors, or working in anything where a client could sue. The limited liability and the credibility of a registered company are worth the extra admin at that point. You do not have to get it perfect on day one, because you can convert a sole proprietorship into a company later once the business proves itself. That is a common path, not a mistake. If you want structured help thinking through the money and legal side before you commit, the free six-week FINternship apprenticeship pairs you with mentors who have started real businesses in Singapore. You can apply here when you are ready to build something instead of only reading about it.
Frequently asked questions
Can a student register a sole proprietorship in Singapore?
Yes. If you are a Singapore citizen or permanent resident aged 18 or older, you can register a sole proprietorship through the GoBusiness portal, even while studying. You will need to make a MediSave arrangement if you have outstanding contributions, and you should check any rules from your school on running a business alongside your course.
Can I switch from a sole proprietorship to a Pte Ltd later?
Yes, and many founders do exactly that. You incorporate a new Pte Ltd and transfer the business over to it, then close or let the sole proprietorship lapse. Start simple, prove the idea works, and incorporate once the risk and revenue justify the extra cost and paperwork.
Do I pay CPF if I run a sole proprietorship?
As a sole proprietor you are self-employed, so you do not pay the usual employee CPF, but you do have to make MediSave contributions once your net trade income passes the annual threshold. If you later run a Pte Ltd and pay yourself a salary as an employee-director, normal employer and employee CPF contributions apply to that salary.
Does a Pte Ltd always pay less tax?
No. At low profit a sole proprietor often pays little or nothing because the first $20,000 of personal income is taxed at 0 percent as of June 2026. A Pte Ltd tends to win at higher profits, where the flat 17 percent rate and start-up exemptions beat the higher end of personal rates. Run your own numbers before deciding.
Pick the structure that matches your actual risk and income today, not the one that sounds most impressive. A sole proprietorship gets you moving cheaply; a Pte Ltd protects you when it counts. Start where you are, keep good records, and upgrade when the business earns it.
