How SEPs Pay Medisave
Once IRAS assesses your tax return, CPF Board issues a Medisave Notice with the contribution amount. Pay via CPF e-Cashier, GIRO, or AXS within the deadline. Late payment attracts 18% per annum interest.
Tax Deduction Benefit
Medisave contributions are fully deductible from chargeable income (Section 39, Income Tax Act). For high-bracket SEPs at 22-24% marginal, the contribution effectively costs 76-78% of nominal.
Voluntary Top-Up Above Mandatory
Can voluntarily top up Medisave Account up to the Basic Healthcare Sum (BHS) ceiling — 2026 ~S$71,500. Cash top-up earns 4% guaranteed + tax relief up to S$8,000/yr. Excellent risk-free return.
Ordinary Wage Ceiling Phasing
Singapore is phasing up OW ceiling: 2024 S$72,000 → 2025 S$74,500 → 2026 S$76,500 → 2027 S$80,000. SEPs with higher income still cap at the annual ceiling.
