CPF Cash Top-Up Tax Relief 2026: Up to S$16,000, Who Counts as Family and How It Works
Last verified: 31 October 2026. Short answer: a Singapore Citizen or PR who makes cash top-ups under the CPF Retirement Sum Topping-Up Scheme (RSTU) gets tax relief of up to S$8,000 for top-ups to themselves and another S$8,000 for top-ups to family members each calendar year [IRAS] [CPF]. Relief only counts up to the recipient's Full Retirement Sum (S$220,400 for top-ups in 2026) [IRAS]. Top-ups are irreversible, and relief is given automatically in the following year's assessment [CPF] [IRAS].

Who you can top up for relief
| Recipient | Extra condition |
|---|---|
| Yourself (Special Account below 55, Retirement Account from 55) | None [IRAS] |
| Parents, grandparents and in-laws (including step and adoptive) | None [IRAS] |
| Spouse or siblings with a disability | None [IRAS] |
| Spouse or siblings | Their annual income in the year before the top-up must not exceed S$8,000, including tax-exempt and foreign income [IRAS] |
Top-ups to friends or other relatives are allowed but do not get tax relief [CPF]. Relief goes to the giver, not the recipient [CPF].
How much relief you get
Relief equals the top-up amount up to S$8,000 for self and S$8,000 for family, S$16,000 in total [IRAS]. Cash top-ups to MediSave also count, within the same caps and up to the Basic Healthcare Sum [IRAS]. All your personal reliefs together are capped at S$80,000 per Year of Assessment [IRAS].
| Year of Assessment | Top-ups made in | Full Retirement Sum | Basic Healthcare Sum |
|---|---|---|---|
| YA 2026 | 2025 | S$213,000 | S$75,500 [IRAS] |
| YA 2027 | 2026 | S$220,400 | S$79,000 [IRAS] |
IRAS example: Mr Tan, under 55, tops up S$5,000 to his own Special Account and S$10,000 to his mother's Retirement Account in 2025. He gets S$13,000 of relief for YA 2026: S$5,000 for himself and S$8,000 (capped) for his mother [IRAS].
What does not qualify
- Transfers from your own CPF savings (CPF transfers) do not get tax relief [IRAS] [CPF].
- Top-ups that attract the Matched Retirement Savings Scheme grant (from 1 January 2025) or the Matched MediSave Scheme grant (from 1 January 2026) do not get relief [IRAS].
- Any amount above the recipient's Full Retirement Sum; members 55 and over can still top up to the Enhanced Retirement Sum (S$440,800 in 2026) for higher payouts, but without relief on the excess [IRAS] [CPF].
How to make a top-up
- Check your own and your family member's top-up limit and eligible relief on the CPF Retirement Dashboard [CPF].
- Make the cash top-up online through CPF, or set up recurring top-ups by GIRO; CPF also has a PayNow guide [CPF].
- Make sure CPF receives your application by 31 December for relief in the next Year of Assessment [IRAS].
- You do not need to claim: IRAS grants the relief automatically from CPF's records [IRAS].
Think before you top up
Top-ups cannot be withdrawn for other purposes and are reserved for monthly retirement payouts [CPF]. IRAS also says there is no refund for accepted top-ups, so check that you are not already near the S$80,000 relief cap [IRAS]. CPF notes that topping up in January rather than December earns more interest over time [CPF]. See our income tax rates to estimate what the relief is worth to you.
