Sole proprietorship in Singapore is perfect if you want to test an idea, take your freelance work seriously, or start lean. But even a simple setup deserves a second look, especially when your name is legally tied to every decision.
This guide will help you make sense of the process, the paperwork, and the practical choices that come with being your own boss.
What is a sole proprietorship?
A sole proprietorship in Singapore is the most straightforward business structure, where the business and the owner are legally the same entity. As the sole proprietor, you have complete control over operations and retain all profits, but you’re also personally liable for any debts or legal obligations.
This structure is ideal for freelancers, consultants, and small business owners who want a low-cost, low-compliance way to operate under a registered business name.
Who can register a sole proprietorship in Singapore?
You can register a sole proprietorship in Singapore if you are:
- A Singapore Citizen, Permanent Resident, or EntrePass/ONE Pass/Tech.Pass holder
- At least 18 years old
- Not an undischarged bankrupt (unless you have court or official approval)
Before applying, make sure you have a local business address and a clear idea of your business activity (SSIC code).
Foreigners can set up a sole proprietorship but need a local authorised representative. Planning to run it from abroad? You’ll need MOM’s green light. Full details coming up.
Pros of registering a sole proprietorship in Singapore
Running lean, fast, and on your own terms? A sole proprietorship in Singapore lets you do just that. Here’s why it’s a go-to for solo founders and side hustlers.
- Full control, no red tape
You run the business your way. No shareholders, no board meetings. If you’re a freelance designer or selling bakes from home, you can make decisions fast and pivot quickly. - Affordable and fast to register
Registering with ACRA costs as little as S$115 and can be done online in under an hour. No paid-up capital required. Perfect for side hustlers or new service providers testing the waters. - Low compliance, fewer admin headaches
You don’t need to appoint a corporate secretary or file annual returns. Just keep track of your income and expenses and file your personal tax return with IRAS. - Personal income tax applies
Your profits are taxed at personal income tax rates, which are progressive in Singapore. For example, if your chargeable income is under S$40,000, your tax payable could be very low or even zero, especially after applying common personal reliefs such as the Earned Income Relief, CPF relief, or NSman relief if you are eligible.
- Easy to shut down
If things don’t work out, closing your business is as easy as logging into BizFile+ and filing a cessation. No legal fees or complex exit procedures.
Cons of registering a sole proprietorship
For all its benefits, a sole proprietorship has real downsides too. From liability to limited growth, here’s what you need to watch out for.
- You’re personally liable for everything
There’s no legal buffer between you and your business. If a customer sues you or you default on a supplier payment, your personal savings or HDB flat could be at risk. - Less trust with clients and lenders
Government grants and corporate clients often prefer to work with registered companies (Pte Ltds). For example, some Startup SG grants require you to be incorporated. - Limited growth and funding options
You can’t bring on investors or issue shares. If you’re planning to build a scalable tech startup or expand regionally, this structure can hold you back. - No access to corporate tax perks
Sole proprietors don’t qualify for the Start-up Tax Exemption (SUTE) or partial tax exemption schemes meant for companies. Over time, this could mean paying more tax than a Pte Ltd would. - Harder to separate personal and business finances
While you can open a business bank account, there’s no legal distinction between your money and the business’s. This can get messy during tax season or when applying for a home loan.
Documents required to set up a sole proprietorship in Singapore

- Local Singapore address (home or office)
- NRIC or FIN copy
- Proof of residential address
- Declaration of Compliance and Non-Disqualification
If you're self-employed, ensure your Medisave contributions are up to date with CPF before applying.

Sole proprietorship in Singapore for foreigners: What to consider
If you’re a foreigner based overseas and want to set up a sole proprietorship in Singapore, there are a few extra steps you must follow:
- Appoint a local authorised representative who is at least 18 years old and legally residing in Singapore (must be a Singapore Citizen, PR, or a holder of an EntrePass or Employment Pass).
- You cannot submit the BizFile+ application yourself unless you have a SingPass account. Instead, you must engage a registered filing agent, such as Sleek, a law firm, or an accounting or corporate secretarial firm, to submit the application on your behalf.
- If you plan to relocate and personally manage your business in Singapore, you’ll need to obtain approval from the Ministry of Manpower (MOM) and hold a valid work pass (e.g., EntrePass, ONE Pass, Tech.Pass, or a Dependant’s Pass with a Letter of Consent).
Many foreign entrepreneurs find it more flexible to register a Private Limited Company, which opens more visa options and access to grants.
