Who can set up a sole proprietorship or partnership in Singapore

Requirements for a Singapore Sole Proprietorship Registration

  • Natural person, at least 18 years of age, or a Singapore registered company; Singapore Citizens or PRs must ensure that their Medisave has sufficient funds before registration
  • A local manager who is either a Singapore Citizen or Permanent Resident, at least 21 years of age
  • A Singapore-based manager for foreign individuals and companies
  • Proposed business name
  • Local business address

What Do You Need to Know Before Registration?

Business Name

The business name must be approved by ACRA before the Singapore Business can be registered. ACRA will reject a proposed business name if:

  • It is identical to another existing Company Name
  • It is undesirable
  • It is similar to established Names and Trademarks such as Coca-Cola and Temasek


Appointment of a manager for Singapore Sole Proprietorship is required only if it is registered by a foreign individual or company. The manager must be an “ordinary” resident in Singapore, which means a Singapore citizen, a Singapore permanent resident, or a person who holds an Employment Pass, EntrePass, or a Dependants’ Pass.

Registered Address

Every business registered in Singapore is required to have a registered office address. The registered address must be a physical address and cannot be a PO Box. The use of residential addresses is allowed for certain types of businesses.

Opening of a Corporate Bank Account

Once the Sole Proprietorship has been registered, you may open a corporate bank account with any of the local or international banks based in Singapore.

Features of a Sole Proprietorship

  • It does not have a separate legal entity
  • The owner has unlimited liability
  • It cannot own property

Advantages of Sole Proprietorship

  • No annual returns filing is required of a Sole Proprietorship as income is taxed at the personal income tax rate.
  • Very few compliance requirements and written documentation.
  • The business itself is flexible. Any decisions and changes can be made easily as there is only one person to make the relevant choices.
  • All the profits generated by the business will belong to the Sole Proprietor.
  • Sole Proprietor owns his business, so is able to sell or transfer it as he wishes.
  • Easy to administer and manage because of undivided authority and control.
  • Less administrative duties, and ongoing compliance requirements.
  • All the profits generated by the business will be taxed at the personal income tax level.

Disadvantages of Sole Proprietorship

  • A Sole Proprietorship has unlimited liability. This means that the Sole Proprietor is responsible for all debts and losses of the business, which can put all personal assets at risk.
  • In the event of a business failure, the creditors can sue the sole proprietor for all debts incurred.
  • As there is only one person with overall responsibility for the success of the business this may increase the pressure on that individual.
  • If the registration of the sole proprietorship/ partnership is not renewed on time, the Registrar has the authority to cancel the business.
  • Lack of continuity; the business is identified with the owner and therefore not perpetual and it ceases with the death of the owner and is not transferable by part.
  • Sole proprietors do not enjoy tax exemptions and rebates available to corporations.

Post-Registration Considerations and Compliance for Sole Proprietorship in Singapore

Licenses and Permits

Some business activities in Singapore are subject to regulation by government authorities. Even if your business firm has been registered you cannot begin operation unless you have the necessary approval or license from the relevant government authorities.

Registered Office Hours

You must have a registered office address and the office must be open to the public for a minimum of three hours per day during normal business hours on weekdays.

Registration Number

Business registration numbers issued by ACRA must be on all letterheads, invoices, billings or other documents used for official business communications.

Customs Registration

If your business activities involve import, export and trans shipment in and out of Singapore, you will need to register your business with the Singapore Customs and obtain a Central Registration Number, commonly known as CR Number. The central registration number is mandatory for Singapore companies or organizations engaged in trading activities.

Singapore Goods and Services Tax Registration

Goods and Services Tax (GST) is a tax on the supply of goods and services in Singapore and on the import of goods into Singapore. Goods exported from Singapore and international services provided from Singapore are exempt from GST. The current rate is 9% (w.e.f. 1st January 2024).

All Singapore businesses must register for GST if their annual taxable revenue is more than S$1 million, or currently making taxable supplies and the annual taxable revenue is expected to be more than S$1 million. The business is expected to register for GST within thirty days from the time it is deemed liable.

You may also choose to register for GST voluntarily. Approval for voluntary registration is at the discretion of the Comptroller in IRAS. Once approval is given, you must remain registered for at least two years.

Registration of Singapore Central Provident Fund (CPF)

The Central Provident Fund or CPF is a compulsory pension fund scheme in which the employer and employee contribute a percentage of the monthly salary to the fund.

CPF contribution by the employer is mandatory for all local employees who are Singapore citizens or permanent residents earning more than S$50 a month.

The maximum CPF contribution rate for employers and employees is 14.5% and 20% respectively and can be lower depending on certain factors such as employee age, permanent resident status, etc.

Tax on Singapore Sole Proprietorship

A Singapore Sole Proprietorship, though a tax resident, is not considered as a company entity; therefore its profit is taxed at Singapore personal income rate. To learn more on the tax rates, please refer to Singapore personal tax rates.

In the event where the owner is a company, the profit from the Sole Proprietorship will be taxed at the corporate tax rate.

Approval and Renewal Information

InCorp can help you register a Sole Proprietorship with ACRA within a few minutes. Once approved, ACRA sends out a confirmation of registration via email. The registration is valid for one year and is subject to an annual renewal. Sole proprietors will be required to top up their Medisave accounts as a pre-condition to renewal.

Cessation of Sole-Proprietorship Business

A Singapore sole proprietorship business will cease when the proprietor either dies or otherwise ceases to carry on business. The Business Registration Act requires any person registered under it who has ceased to carry on business to notify the Registrar of this. Failing to do so is an offence and may result in the imposition of a fine.
