CPF Voluntary Contribution Singapore
Beyond mandatory CPF deductions from employment, Singapore residents can boost retirement savings through voluntary CPF contributions. Understanding the types, limits and tax relief available can significantly accelerate your retirement plan. This is not financial advice.
Types of CPF Voluntary Contributions
There are several types: (1) Self-employed MediSave contributions — mandatory above S,000 net trade income but may be topped up voluntarily; (2) Retirement Sum Topping-Up Scheme (RSTU) — cash or CPF OA transfers to your own or a family member’s SA (below 55) or RA (55+); (3) Voluntary OA/SA/MA top-ups for employees contributing beyond mandatory deductions.
Retirement Sum Topping-Up Scheme (RSTU)
Under RSTU, cash top-ups to your own CPF Special Account (below 55) or Retirement Account (55+) earn up to S,000 tax relief per year. Top-ups to a parent’s, grandparent’s, spouse’s or sibling’s CPF account earn a further S,000 tax relief — total possible: S6,000/year. Note: CPF OA-to-SA transfers are irrevocable. Use the CPF Retirement Sum Calculator to model how top-ups accelerate reaching the FRS.
CPF Annual Limit 2026
The CPF Annual Limit for 2026 is S7,740. This is the maximum combined employer+employee+voluntary contribution across all CPF accounts per year. If your mandatory contributions already reach this limit, further voluntary contributions are not possible. Use the CPF OA/SA allocation calculator to see your available top-up headroom.
Tax Relief Summary
- RSTU cash top-up to own SA/RA: up to S,000 relief/year
- RSTU cash top-up to family member’s SA/RA: up to S,000 additional relief
- Self-employed MediSave contributions: full deduction against assessable trade income

Frequently Asked Questions
Can I voluntarily top up my CPF OA and get tax relief in Singapore?
Voluntary top-ups directly to the Ordinary Account (OA) alone do not attract additional personal income tax relief. For tax relief, top up your Special Account (below 55) or Retirement Account (55+) under RSTU — this gives up to S,000 relief per year.
What is the maximum voluntary CPF contribution I can make in 2026?
The CPF Annual Limit for 2026 is S7,740 (combined employer+employee+voluntary). Your voluntary top-up space equals S7,740 minus your actual mandatory contributions for the year.
Is it better to top up CPF SA or invest in stocks?
CPF SA earns a guaranteed 4% p.a. (with 1% extra on the first S0,000). For risk-averse investors near retirement, this is hard to beat net of fees. Long-term investors with higher risk tolerance may generate higher returns in equities but with greater volatility. This is not financial advice.
Can I top up my parents' CPF and get tax relief?
Yes. Cash top-ups to a parent, grandparent, spouse or sibling’s CPF Special or Retirement Account qualify for up to S,000 additional tax relief per year under RSTU.
What happens to voluntary CPF contributions if I emigrate from Singapore?
Singaporeans or PRs who renounce citizenship or PR status may withdraw their CPF savings in full, subject to CPF Board rules. MediSave balances may be retained for medical use if you maintain Singapore residency.
