How Self-Employed Tax Works in Singapore

Net trade income = Revenue − allowable business expenses − MediSave contribution − voluntary CPF

Income tax is then calculated on net trade income plus any other income (dividends, rental, etc.) at progressive rates of 0–22%.

MediSave is mandatory if net trade income > S$6,000/year. Rates range from 8% (age ≤34) down to 3.5% (age ≥65), capped at the MediSave Annual Contribution Limit.

File Form B (not Form B1) each year by 18 April. Keep records of all business income and expenses for at least 5 years.
