Supplementary Retirement Scheme (SRS)
SRS contributions are tax-deductible up to S$15,300/year (Singapore citizens/PRs) or S$35,700 (foreigners). Investments inside SRS grow tax-free until withdrawal at retirement age.
CPF-OA investing
You can invest CPF Ordinary Account savings above S$20,000 in approved unit trusts and ETFs (CPFIS). The CPF-OA interest rate is 2.5% — if you invest in equities and outperform 2.5% over time, investing makes sense. But CPF-OA money is locked until 55, so choose carefully.
Regular savings plans (RSPs)
All major brokerages in Singapore offer RSPs that debit monthly and buy ETFs like the Nikko AM STI ETF or CSPX (S&P 500). Minimum S$100/month. This is Singapore's equivalent of a SIP.
