Singapore CPF Self-Employed MediSave Calculator
Self-employed Singaporeans and PRs must contribute to MediSave each year based on Net Trade Income (NTI). This free calculator uses official 2026 IRAS/CPF age-tier rates to show your annual and monthly MediSave obligation. All calculations run privately in your browser.
Who Must Contribute to MediSave as Self-Employed
If you are a Singapore Citizen or Permanent Resident aged 21 and above and you earn a Net Trade Income (NTI) of at least S$6,000 in a calendar year from any trade, business, profession, or vocation, you are legally required to contribute to your CPF MediSave Account. This applies to freelancers, sole proprietors, hawkers, private-hire drivers, commission agents, tuition teachers, and gig workers. NTI is your gross revenue minus allowable business expenses, declared each year in your IRAS income tax return. If your NTI is below S$6,000, no contribution is required but voluntary top-ups still attract tax relief.
MediSave Rates by Age 2026
CPF applies a tiered rate schedule to the lower of your NTI or the Income Ceiling (S$102,000 for 2026). The 2026 rates are: below 35 years old pays 8.0%, aged 35 to below 45 pays 9.0%, aged 45 to below 50 pays 10.0%, and 50 and above pays 10.5%. The rate used is based on your age in the contribution year. Contributions are also subject to the Basic Healthcare Sum (BHS) cap, projected around S$75,000 for 2026. If your MediSave balance has already hit the BHS, the excess flows to your Special or Retirement Account automatically.
How to Pay (CPF Mobile App)
After you file your Form B / B1 with IRAS, the CPF Board issues a Notice of Computation showing the MediSave amount due. Pay via the CPF Mobile app (Contribute menu), PayNow to UEN 201517377E-MBMF, GIRO, or AXS. Paying in full by 15 April avoids late-payment interest charged at 1.5% per month. You may also opt for the Contribute-As-You-Earn (CAYE) scheme for government contracts, where MediSave is deducted automatically at source from each payment.
Tax Relief on Contributions
Mandatory MediSave contributions are tax-deductible against your trade income, reducing your taxable income in the year of contribution. Voluntary top-ups above the mandatory amount qualify for additional relief under the CPF Cash Top-up Relief (up to S$8,000 for self and S$8,000 for family members). Combined with the Supplementary Retirement Scheme (SRS), self-employed Singaporeans can meaningfully reduce their Year of Assessment tax bill while building healthcare and retirement savings. Always verify the latest figures on cpf.gov.sg or iras.gov.sg before filing — rates and ceilings are reviewed annually.
