Sole Proprietorship
An unincorporated business owned by a single individual, with no separation between owner and business.
A Sole Proprietorship is the simplest Singapore business structure: a single individual operating a business in their own name or under a registered business name. There is no legal separation between owner and business - profits are taxed as personal income, and the owner has unlimited personal liability for business debts. Sole proprietorships can only be registered by Singapore citizens, PRs, or EntrePass holders, and the registration is renewed annually. Suitable for very small, low-risk operations; unsuitable for raising investment or scaling.
A freelance designer who registers their business name 'Studio X' as a sole proprietorship pays personal income tax on profits (up to 24% top marginal rate) and is personally liable for any business debt.
