How much CPF top-up tax relief can a self-employed person in Singapore claim?

CPF Top-Up Tax Relief for Self-Employed Persons (SEPs)

For a self-employed person (SEP) in Singapore, tax relief related to CPF contributions and top-ups is governed by specific rules under the Income Tax Act (IRAS). The relief primarily stems from mandatory contributions and voluntary top-ups made to the Special Account (SA) or Retirement Account (RA).

Mandatory Contribution Relief:

SEPs are required to contribute to their CPF accounts (Ordinary, Special, and Medisave). The relief granted is based on the mandatory contributions made to your CPF accounts, up to the prevailing CPF annual salary ceiling. For 2025, the salary ceiling is S$7,400 per month (S$88,800 annually), increasing to S$8,000 per month (S$96,000 annually) in 2026. The relief is calculated on the mandatory contributions made on your self-employed income, subject to the prevailing contribution rates for SEPs.

Voluntary Top-Up Relief (Retirement Sum Topping-Up Scheme - RSTU):

SEPs can also benefit from tax relief when making voluntary cash top-ups to their own or their family members' SA/RA under the RSTU scheme. The maximum amount you can top up annually is limited by the Enhanced Retirement Sum (ERS) for your cohort, or the shortfall between your current retirement savings and the ERS, whichever is lower. For 2025, the ERS stands at S$426,000 (4x the Full Retirement Sum (FRS) of S$213,000).

Overall Relief Cap:

It is crucial to note that the total tax relief claimed from all sources, including mandatory CPF contributions, RSTU top-ups, and other reliefs (like life insurance premiums), cannot exceed the overall personal relief cap of S$80,000 (IRAS). Additionally, SEPs are eligible for an S$8,000 self top-up relief and an S$8,000 family top-up relief, which contribute towards this S$80,000 cap.

In summary, the relief for SEPs covers mandatory contributions up to the salary ceiling and voluntary RSTU top-ups, all subject to the S$80,000 aggregate relief cap.
