Sole Proprietorship Singapore

Registering the business and legal aspects

The sole proprietorship is the simplest business structure adoptable in Singapore. Its registration process is extremely streamlined and requires minimum effort from the business owner.

It allows to carry out most activities in Singapore without many filing obligations with the local authorities. All about Sole Proprietorship Singapore just below.

Register a Sole Proprietorship in Singapore

In order to register a Sole Proprietorship the owner must:

  • Be a Singapore Citizen or Permanent Resident 18 years old and above. The Sole Proprietorship is not an available for Foreigners wanting to do business in Singapore, check our guide here: STARTING MY BUSINESS IN SINGAPORE 
  • Choose a Business Name for your Sole Proprietorship and select the main activities the business will be carrying out. The main activities must be selected among the ones listed in the Singapore Standard Industrial Classification (SSIC) code. The business name chosen must be different from other businesses so to be able to be recognizable and respect the criteria imposed by the local company registry (no obscene names, as well as vulgar or offensive). Once the name is reserved it will stay so for 120 days until the business owner confirms it, otherwise it will be realized for others to be selected. 
  • Select an Address for the business. This can be a residential one, provided the HDB or URA (Urban Redevelopment Authority) grant approval through the Home Office Scheme. A P.O. box can’t be chosen as business address for the Sole Proprietorship. 
  • Provide the following documents:
    • Proposed Business Names
    • Proposed Business address and owner’s address
    • Brief Description of the business activities
    • Copy of the Owner’s ID
    • Declaration of compliance and statement of non-disqualification 

The application with the Company Registry usually takes less than a working day to be approved.

Sole Proprietorship Singapore

There are significant limitations to consider when selecting a Sole Proprietorship, most importantly:

  • It is not a separate legal entity from its business owner. This means that the entrepreneur will be directly and personally liable for all the debts and losses incurred by the Sole Proprietorship, without limitation.
  • This business structure is not fit to be scaled up. Investors might be reluctant to inject funds in the business and there are no partners in the sole proprietorship.
  • As mentioned before in this guide, it is not available for Foreigners residing in Singapore. As a foreigner we would recommend you to incorporate a Private Limited Company.

Ultimately, the Sole Proprietorship is the right entity choice for businesses involved in activities that pose very little to no risk.

Sole Proprietorship registration and maintenance requires limited compliance obligations and it’s most suitable for single-owner businesses as it requires the business owner to be fully involved in the management and control of the business. 

Tax Framework for a Sole Proprietorship owner

The owner of a Sole Proprietorship is generally considered a self-employed person in the eye of the Tax Authority in Singapore. This means that, among other obligations, the business owner is required to declare the income derived from the activities of the sole Proprietorship in a selected accounting period.

This is usually a 12-month long period for you to calculate the profits or losses from the sales of goods/provision of services of the business.  It is important for Sole Proprietors to keep track of their sales and expenses by maintaining supporting evidence such as vouchers, receipts or invoices. In fact, IRAS will not accept inaccurate and incomplete accounts.

At the end of the accounting period, most sole proprietorships choose 1 January to 31 December, the business owner is required to prepare a Statement of Accounts (SoA). This is a much simpler way of representing the financial position of a Sole Proprietorship and it can be in the form of a 2-line SoA or 4-line SoA:

2 Line Statement of Accounts 
First LineRevenue 
Second LineAdjusted Profit and Loss
4 Line Statement of Accounts 
First LineRevenue
Second LineGross Profit/Loss
Third LineAllowable Business Expenses
Fourth LineAdjusted Profit and Loss

As the Sole Proprietorship is not a separate legal entity from the business owner, the income generated from the business activities must be reported in the personal Income Tax Declaration of the business owner and it will be taxed and the Individual Income Tax Rates.

Singapore adopts progressive marginal rates (0% to 24%) to tax resident individuals, which means that higher earners will pay proportionate higher tax rates, and for the income generate in the year 2023 and beyond, the highest rate is 24% (for 1 million SGD income and above).

This change has been implemented to achieve greater progressivity with the top marginal income rate for top earners raised from 23% to 24%.

Singapore allows for free circulation of capital. Foreign individuals or foreign companies are allowed to own 100% of the shares in a Singapore company.

Understanding the different level of liability when selecting the right entity type is crucial for every business owner. Private Limited companies have the great advantage to offer limited liability to their investors / founders, limited to the contributions they have injected in the Private Limited company.

On the other end, the liability of the business owner who has registered a sole proprietorship is, by definition, unlimited. The entrepreneur is therefore directly responsible for all the debts and obligations of the sole proprietorship.
