CPF is not a tax: that 20 % is still yours
This is the first thing to understand before comparing Singapore with any European country. The 20 % that leaves your payslip for the Central Provident Fund is deducted just like a social contribution, which is why it appears in the breakdown, but the state does not keep it: it goes into YOUR account.
It is split across three sub-accounts — retirement, housing and healthcare — and that money pays the deposit on a flat or a medical procedure. Nine in ten Singaporeans own their HDB flat, bought largely with those same contributions.
Comparing Singapore's «total withheld» with Spain's without knowing this leads to a false conclusion. Here, most of what is withheld is still yours; there, it is not.
The scale really is flat at the bottom
The first 20,000 $ pay absolutely nothing, and up to 80,000 the average rate does not reach 5 %. People comparing gross salaries between Singapore and Europe usually forget that the real difference is here, not in the salary.
That gentle scale has a consequence that looks like a bug and is not: total effective pressure FALLS in the middle of the table. Someone on 200,000 $ hands over a smaller share of their gross than someone on 30,000, because CPF caps at 96,000 and the tax has not yet bitten. It rises again at a million.
And a third detail works in your favour: CPF is DEDUCTED from the taxable base. It is simultaneously the largest deduction from and the largest relief on almost any payslip, so below the ceiling an extra dollar is only taxed on 80 cents of itself.
Where these figures come from
The resident scale is the IRAS table in force from assessment year 2024: thirteen brackets, from 0 % to 24 %. The CPF rates and the 8,000 $ monthly ceiling come from the CPF Board, in force since 1 January 2026. The reliefs — Earned Income Relief, Spouse Relief and Qualifying Child Relief — come from IRAS's own factsheets.
Verification rests on three legs. The scale reproduces the TWELVE cumulative tax figures IRAS publishes alongside its rates, which proves all thirteen rates and twelve thresholds at once. The whole machine is checked against IRAS's own worked example — 50,000 $ with one child — which comes out identical bar 8.75 $, exactly 3.5 % of a 250 $ donation this tool does not ask about. And an independent calculator agrees on CPF to the cent at three different salaries.
What this calculator does not include
- The Parenthood Tax Rebate. In IRAS's own example it swallows the entire bill of a parent with one child, but it is a ONE-off allowance per child, carried forward until used up. Applying it every year would leave any parent with zero tax forever.
- The Working Mother's Child Relief, which can be worth far more than the child relief — 15 % of income for the first child — but only the mother receives it, and this tool does not ask about sex.
- The annual rebate, announced in each budget and different every year.
- Reliefs that depend on spending or personal choices: dependent parents, SRS, life insurance, courses, national service, donations.
- Age. Everything is computed for the 55-and-under band; above it both the CPF rates and the Earned Income Relief change.
- That only citizens and permanent residents pay CPF. A foreigner on an Employment Pass does not contribute, so they take home more net and pay more tax, because they lose their largest relief.
