What self-employment means in Singapore
In Singapore, you are self-employed if you earn income from a trade, business, profession, or vocation. The most common starting point is as a sole proprietor, registered with ACRA (Accounting and Corporate Regulatory Authority) via the BizFile+ portal.
Self-employed individuals file income tax via Form B with IRAS. Unlike employees, no tax is withheld at source. You must also make voluntary or mandatory CPF (Central Provident Fund) contributions depending on your citizenship status.
| Status | Tax filing | Liability | Registration |
|---|---|---|---|
| Employee | Employer files via Auto-Inclusion Scheme | Employer's | None |
| Sole Proprietor | Form B with IRAS (self-assessment) | Personal (unlimited) | ACRA BizFile+ |
| Private Limited (Pte Ltd) | Form C/C-S corporate tax | Limited to company assets | ACRA incorporation |

Common mistakes to avoid
Not registering with ACRA
Operating a business without ACRA registration is an offence. Even freelancers earning from a trade or profession should register.
Missing MediSave contributions
Singaporean/PR self-employed must contribute to MediSave. Failure to do so results in penalties from CPF Board.
Underestimating tax obligations
No tax is withheld at source. Set aside 10-20% of income for tax payments to avoid cash flow surprises.
Not keeping proper records
IRAS requires 5 years of record retention. Poor records can lead to assessment by IRAS at higher estimated amounts.
Exceeding GST threshold without registration
If your turnover retrospectively exceeds S$1 million, you must register within 30 days. Late registration incurs penalties.
