Starting a business is exciting, but one of the first and most important decisions you will make is choosing the right business structure.
In Singapore, common business structures include a Sole Proprietorship, Partnership, Limited Liability Partnership (LLP) and Private Limited Company. Each has its own legal, tax and compliance implications.
The right choice depends on factors such as your business goals, appetite for risk, number of owners and future growth plans.
This guide explains the key differences between each business structure so you can make an informed decision before registering your business.
👁️🗨️ At a Glance
Which business structure should you choose?
Business Type | Suitable For |
Sole Proprietorship | Individuals testing a business idea or operating a small business on their own |
Partnership | Two or more individuals running a business together |
Limited Liability Partnership | Partners who want limited liability while maintaining a relatively simple business structure |
Private Limited Company | Businesses seeking limited liability, continuity and greater flexibility for future ownership or investment |
Why Your Business Structure Matters
Choosing a business structure affects much more than your registration.
It determines:
- Your legal liability
- How profits are taxed
- Your compliance obligations
- Your ability to raise funds
- How customers, suppliers and investors perceive your business
- Whether the business can continue if ownership changes
Changing your business structure later is possible but may involve additional costs and administrative work. Spending time to choose the right structure at the beginning can save you significant time and money in the future.
Sole Proprietorship
A sole proprietorship is owned by one individual. It is the simplest and least expensive business structure to set up.
However, a sole proprietorship is not a separate legal entity. This means the owner and the business are legally the same person.
Advantages
- Simple to register
- Lower compliance requirements
- Full control over business decisions
- Relatively inexpensive to maintain
Disadvantages
- Unlimited personal liability
- Difficult to raise investment
- Business ends if the owner ceases operating
- Profits are taxed as the owner’s personal income
Partnership
A partnership consists of two or more individuals carrying on a business together.
Like a sole proprietorship, a partnership is generally not a separate legal entity.
Each partner may be personally liable for the debts and obligations of the business.
Advantages
- Easy to establish
- Shared responsibilities
- Shared capital
- Suitable where partners have complementary skills
Disadvantages
- Partners may be jointly liable
- Disagreements can affect the business
- One partner’s actions may expose the other partners to liability
Private Limited Company
A private limited company is a separate legal entity from its shareholders.
A private limited company provides limited liability for its shareholders and greater flexibility for changes in ownership and raising capital, but it also comes with higher compliance and administrative requirements.
Advantages
- Limited liability for shareholders
- Separate legal identity
- Easier to raise capital
- Greater business credibility
- Ownership can change without affecting the company’s existence
- Eligible for various tax incentives available to qualifying companies
Disadvantages
- More compliance requirements
- Annual filings with ACRA
- Corporate secretarial obligations
- Higher administrative costs compared to a sole proprietorship
What About a Limited Liability Partnership (LLP)?
A Limited Liability Partnership (LLP) combines some features of a partnership with the benefits of limited liability.
Unlike a general partnership, an LLP is a separate legal entity. This means the LLP can own assets, enter into contracts and continue to exist even if the partners change.
Each partner is generally not personally liable for the wrongful acts or negligence of another partner. However, each partner remains responsible for their own actions.
Advantages
- Separate legal entity
- Partners generally enjoy limited liability
- Suitable for businesses with two or more owners
- Relatively lower compliance requirements than a private limited company
Disadvantages
- May not project the same level of credibility as a private limited company
- Does not issue shares, making it less suitable for raising investment
- Partners remain responsible for complying with LLP regulations
Suitable For
An LLP is commonly used by:
- Professional practices
- Family businesses
- Small businesses with two or more owners
- Businesses where partners want limited liability without incorporating a company
Comparison Table
Sole Proprietorship | Partnership | Limited Liability Partnership | Private Limited Company | |
Separate Legal Entity | No | No | Yes | Yes |
Personal liability | Unlimited | Generally unlimited | Generally limited | Limited |
Number of Owners | One | Two or more | Two or more | One or more shareholders |
Income Tax Treatment | Personal Income Tax | Personal Income Tax | Personal Income Tax | Corporate Income Tax |
Set-up and administration | Simplest | Relatively simple | Moderate | More complex |
Ongoing compliance | Low | Low | Moderate | Higher |
Ownership changes | No | Depends on partnership arrangements | Partners may change while the LLP continues | Shares can be transferred or new shares issued |
Bringing in investors | Limited | Limited | Limited | Can issue shares to investors |
Business Continuity | Ends with owner | Depends on partnership agreement | Continues despite changes in partners | Continues regardless of ownership changes |
Suitable where | One owner values simplicity and has limited need for external investment | Two or more owners want a relatively simple structure | Two or more owners want limited liability without incorporating a company | Limited liability, continuity, ownership flexibility or external investment are important |
Understanding the Costs
While the cost of setting up a business is an important consideration, it should not be the only deciding factor.
Sole Proprietorship and Partnership
These structures are relatively inexpensive to register and have minimal ongoing compliance requirements. However, the owners are personally liable for the debts and obligations of the business.
Private Limited Company
A private limited company generally costs more to set up and maintain because it must comply with the Companies Act. Ongoing costs may include:
- Corporate secretarial services
- Accounting and bookkeeping
- Preparation of financial statements
- Annual Return filing with ACRA
- Corporate income tax filing

The higher cost should therefore be weighed against the benefits the company structure provides. If limited liability, business continuity, ownership flexibility or the ability to bring in investors are important to your business, the additional compliance cost may be justified. If these factors are not important, a simpler structure may be more appropriate.
Which Structure Is Right for You?
Consider a Sole Proprietorship if you:
- Are starting alone
- Want a simple and inexpensive structure
- Are testing a business idea
Consider a Partnership if you:
- Are starting a business with one or more partners
- Want a simple structure
- Understand that partners are personally liable for the business
Consider a Limited Liability Partnership (LLP) if you:
- Have two or more business partners
- Want limited liability
- Do not intend to raise external investment
An LLP is commonly used by professional practices such as consultants, architects and designers.
Consider a Private Limited Company if you:
- Want to limit your personal liability
- Want the business to continue independently of changes in ownership
- Expect to bring in investors or additional shareholders
- Want greater flexibility to transfer or restructure ownership
- Expect to deal with customers, suppliers, lenders or investors who may prefer dealing with an incorporated company
- Want access to corporate tax incentives available to qualifying companies
- Are prepared for the higher administrative and compliance requirements
⚠️ Common Mistakes to Avoid
❌ Choosing the cheapest structure without considering future growth
❌ Assuming you can easily convert later
❌ Not understanding the risks of unlimited liability
❌ Overlooking ongoing compliance obligations
💡 Prologue Tip
Many entrepreneurs focus on the cost of setting up a business. However, choosing the right business structure should be based on where you want your business to be in the next three to five years, not just where it is today.
Consider what may change over that period, such as the number of owners, your need for external investment, the level of business risk and how important continuity and ownership flexibility may become.
Frequently Asked Questions
Can I change from a sole proprietorship or a partnership to a company later?
Yes. However, this is generally not a direct conversion. You will usually need to incorporate a new private limited company and transfer the business operations, assets, contracts and, where applicable, licences from the sole proprietorship or partnership to the new company.
Before making the transition, it is advisable to consider the legal, tax and operational implications and seek professional advice where necessary.
Is a private limited company always better?
Not necessarily. It depends on your business objectives and expected growth.
Can one person own a private limited company?
Yes. A private limited company may have only one shareholder.
Do I need a company secretary for a sole proprietorship or a partnership?
No. Company secretaries are required only for companies incorporated under the Companies Act.
