Freelance & Self-Employed Tax Calculator Singapore 2026
Estimate income tax and MediSave contributions for freelancers and self-employed in Singapore. Enter your revenue, deductible business expenses, and compare against equivalent employment income.
Business Expenses (tax-deductible)
Self-employed can make voluntary CPF contributions (OA/SA). Tax-deductible up to annual limit.
MediSave (S$5,760/yr) is contributed to CPF — not cash out-of-pocket but reduces liquid take-home.
Estimates based on IRAS YA2025 rates. Mandatory MediSave contribution applies if net trade income > S$6,000/year. Consult a tax professional for complex situations. Source: iras.gov.sg
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.
