What is a Sole Proprietorship?
A sole proprietorship is the simplest business structure for one owner in Singapore. The business and the owner are not separate legal persons, so the owner keeps control of the business but is also personally responsible for its debts and obligations.
This structure can suit a small, owner-operated business where the compliance burden needs to stay light. The trade-off is unlimited liability. If the business cannot meet its obligations, the owner’s personal assets can be exposed.
If you are deciding between a sole proprietorship, LLP and company, the key differences are liability, tax treatment, continuity and compliance. We cover those differences further below.
Quick Facts
- A sole proprietorship is not a separate legal entity from its owner. The owner is personally responsible for the business's debts and obligations.
- The owner must be at least 18 years old.
- If the owner is not locally resident in Singapore, a locally resident authorised representative is required.
- A Singapore business address is required. A P.O. Box cannot be used as the business address.
- Singapore citizen and PR owners who are self-employed must keep their Medisave obligations up to date.
- Business income is reported by the owner and taxed under the individual income tax rules that apply to the owner.
- A sole proprietorship does not have perpetual succession. The business is tied to its owner.
- There is no company-style annual return filing requirement with ACRA.
- The registration must be renewed to keep the business active.
- The owner should keep proper business records and meet the tax obligations that apply to self-employed persons.
How is a sole proprietorship different from an LLP or company?
The biggest difference is legal separation. A private limited company and an LLP are separate legal persons. A sole proprietorship is not.
That means a sole proprietor has unlimited liability for the business. A company shareholder or LLP partner usually has more protection from business liabilities, subject to the rules that apply to that structure and the person’s own conduct.

Advantages of a Sole Proprietorship
- Simple to set up and maintain compared with a company.
- The owner keeps full control over business decisions.
- Profits belong to the owner and there is no need to manage shareholder distributions.
- Closing the business is usually simpler than winding up a company.
- Ongoing ACRA compliance is relatively light, although registration renewal, record-keeping and tax obligations still apply.
Disadvantages of a Sole Proprietorship
- The owner has unlimited liability for business debts and obligations.
- Personal assets can be exposed if the business cannot meet its liabilities.
- Business income is taxed under the owner's individual income tax position rather than the corporate income tax regime.
- The business does not have perpetual succession and is closely tied to the owner.
- Raising investment can be more difficult because there are no shares to issue to investors.
What do you need to register a sole proprietorship?
- An approved business name and the related name application details
- The business activity and proposed commencement date
- A Singapore business address and business email address
- The owner's identification and residential details
- A locally resident authorised representative if the owner is not locally resident
- Any approvals needed to use a home address under the Home Office Scheme, where applicable
Registration is completed through Bizfile after the business name has been approved. You will enter the business details, add the owner and any authorised representative, review the application and submit the registration.
Foreigners without Singpass must engage a registered corporate service provider to register the business. ACRA’s current sole proprietorship registration guide sets out the information and steps required.
After registration, keep the business registration active, set up Corppass where required, maintain proper records and meet the tax and Medisave obligations that apply to you. If you would like us to handle the registration, see our sole proprietorship registration service or contact us and we will be happy to help.
