Frequently asked questions
How much tax relief do I get for topping up my CPF SA?
Up to S$8,000 per year for topping up your own Special or Retirement Account, plus another S$8,000 for cash top-ups to family members — spouse, parents, parents-in-law, grandparents, siblings. That's up to S$16,000 off your taxable income in a year.
Is CPF SA top-up worth it?
The 4% interest floor — guaranteed by the Government through 2027 and extended year after year — beats any risk-free rate available in Singapore. The catch: the money is locked until 55+ and joins your Retirement Sum. Strong move if you're over 40 with a fat emergency fund; a poor one if your cash buffer is thin.
Can I withdraw my CPF SA top-ups?
No. Cash top-ups are locked in from day one. They go toward your Retirement Sum and eventually fund your CPF LIFE payouts. Treat every dollar topped up as untouchable until retirement.
Should I top up my SA or invest the cash myself?
Compare 4% risk-free against what your own portfolio actually delivers after fees and taxes. Under 35, building skills and an emergency fund usually beats locking money away; the tax relief compounds in value once your marginal rate reaches double digits.
