CPF cash top-up tax relief gives you up to S$8,000 of relief a year for cash top-ups to your own CPF, and up to another $8,000 for top-ups to certain family members. Top-ups made in 2026 count for YA 2027, so the deadline is 31 December 2026.
The relief has more conditions than the headline suggests: who counts as family, an income test for spouses and siblings, limits tied to the Full Retirement Sum, and no relief on top-ups that earn government matching grants.
CPF Cash Top-Up Tax Relief: The Two $8,000 Limits
IRAS gives CPF Cash Top-up Relief on cash top-ups under the Retirement Sum Topping-Up Scheme and to MediSave Accounts:
| Recipient | Accounts | Relief limit per YA |
|---|---|---|
| Yourself (by you or your employer) | Special Account (below 55), Retirement Account (55+), MediSave | $8,000 |
| Family members (combined) | Their Special, Retirement or MediSave Account | $8,000 |
| Anyone else | Any | None |
If you top up $5,000 to yourself, your relief is $5,000. If you top up $12,000 to your parents, your relief is $8,000. Unused room in one limit cannot be moved to the other.
The relief counts towards the $80,000 cap on all personal reliefs. IRAS states there is no refund of top-ups once accepted.
Who Counts as Family, and the Income Test
Family members for relief purposes, according to IRAS:
- No income test: parents, parents-in-law, grandparents and grandparents-in-law (including step and adoptive), and a spouse or sibling with a disability.
- Income test applies: your spouse and siblings. They must not have had annual income of more than $8,000 in the year before the top-up. For top-ups in 2026, that means 2025 income.
Annual income here is broad. IRAS includes taxable income, tax-exempt income such as bank interest and dividends, and foreign income whether or not it was brought into Singapore.
Illustration only. In 2026 you top up $6,000 to your wife’s Special Account. She earned $9,000 from part-time work in 2025. Because her 2025 income was above $8,000, you get no relief for YA 2027.
The short version: $8,000 for you, $8,000 for family, cash only. Parents and grandparents qualify regardless of income; a spouse or sibling must have earned no more than $8,000 the year before.
Matching Grants: When Relief Is Lost
Two government schemes match cash top-ups for members with lower balances:
- Matched Retirement Savings Scheme (MRSS): the CPF Board says it matches top-ups to retirement savings up to $2,000 a year, with a $20,000 lifetime limit. IRAS says matched top-ups have not qualified for relief since YA 2026.
- Matched MediSave Scheme (MMSS): Budget 2026 papers describe it as matching voluntary MediSave top-ups up to $1,000 a year. IRAS says top-ups made from 1 January 2026 that attract MMSS grants do not qualify for relief from YA 2027.
The CPF Board describes it as the portion that attracts the grant losing relief. Illustration only: a $3,000 top-up to a parent who receives the full $2,000 MRSS match would leave $1,000 eligible for relief.
The grant itself is often worth more to the family than the tax relief. Our guide to MRSS and topping up parents or a spouse covers eligibility.
How Much You Can Top Up for Relief
IRAS computes relief only on top-ups within these limits for YA 2027:
| Recipient’s age | Account | Limit for relief |
|---|---|---|
| Below 55 | Special Account | 2026 Full Retirement Sum ($220,400) minus SA savings and SA money invested |
| 55 and above | Retirement Account | 2026 Full Retirement Sum ($220,400) minus RA savings |
| Any | MediSave | 2026 Basic Healthcare Sum ($79,000) minus MediSave balance |
The CPF Board allows Retirement Account top-ups up to the Enhanced Retirement Sum, $440,800 in 2026. Top-ups above the Full Retirement Sum are accepted, but IRAS does not give relief on that part.
Illustration only. A 45-year-old has $215,000 in her Special Account. Only $5,400 of a top-up to her own SA would count for relief, because $220,400 minus $215,000 is $5,400. A top-up to her MediSave, if it is below the Basic Healthcare Sum, could use the rest of her $8,000.
Check exact limits on the CPF Board’s Retirement Dashboard before paying.
What the Relief Is Worth
The tax saved is your marginal rate on the relief. Resident rates for YA 2027 are unchanged from YA 2024:
| Relief claimed | 7% band | 11.5% band | 15% band |
|---|---|---|---|
| $8,000 | $560 | $920 | $1,200 |
| $16,000 | $1,120 | $1,840 | $2,400 |
These assume the relief stays within one band. Our CPF top-up tax relief calculator handles band crossings.
Relief is not the only reason people top up. For yourself below 55, our article on cash top-ups vs OA-to-SA transfers compares the routes.
What To Do Next
- Confirm each family member’s 2025 income if you are topping up a spouse or sibling.
- Ask the CPF Board whether a top-up will attract MRSS or MMSS grants.
- Check limits on the Retirement Dashboard, and leave time for the payment to reach CPF before 31 December; see the year-end tax deadline guide.
- Run the numbers with the CPF top-up tax relief calculator. For complex family situations, ask IRAS or a qualified tax professional.
