Chargeable income is the income Singapore income tax is actually charged on. It is not the same as assessable income: IRAS defines assessable income as total income after deducting allowable expenses and approved donations, and chargeable income as assessable income after deducting personal reliefs. The resident tax rates apply to chargeable income only — and a non-resident, who cannot claim reliefs, ends up with the two figures equal.
Key takeaways
- Assessable income and chargeable income are different figures. IRAS arrives at assessable income by deducting allowable expenses and approved donations from total income, then at chargeable income by deducting personal reliefs from assessable income.
- The resident rates are applied to chargeable income, not to salary or assessable income. Applying the YA 2026 resident rates to IRAS’s example chargeable income of SGD 35,000 gives tax of SGD 375: nothing on the first SGD 20,000, 2% on the next SGD 10,000 and 3.5% on the last SGD 5,000.
- Personal reliefs are capped at SGD 80,000 a Year of Assessment in total, and have been since YA 2018, so assessable and chargeable income can differ by at most that much for a resident.
- Only a tax resident may claim personal reliefs. IRAS’s non-resident examples show reliefs as not applicable, so for a non-resident chargeable income is the same as assessable income.
- The Personal Income Tax Rebate works on tax payable, not on chargeable income. IRAS describes it as a one-off for YA 2024 and YA 2025 — 60% of tax payable, capped at SGD 200 for YA 2025 — and lists none for YA 2026.
Is assessable income the same as chargeable income?
No. IRAS’s computation runs through three income figures, and each step removes something different. Assessable income is what is left after expenses and donations; chargeable income is what is left after reliefs as well.
The tax bill uses shorter labels for the same sum. On the Notice of Assessment IRAS shows Income less Deductions equals Chargeable income, and its “Deductions” line covers both donations and reliefs — which is why the bill and IRAS’s glossary look different but agree.
IRAS’s example, taken through to tax
The income, deduction and relief amounts are IRAS’s illustration for a resident employee — example figures, not standing limits. IRAS’s example stops at chargeable income; the last row is Money Snap’s calculation at the YA 2026 resident rates.
| Step | Amount | Note |
|---|---|---|
| Employment income | SGD 50,000 | total income |
| Less allowable expenses and approved donations | − SGD 5,000 | |
| Assessable income | SGD 45,000 | IRAS definition |
| Less personal reliefs | − SGD 10,000 | residents only |
| Chargeable income | SGD 35,000 | the rates apply here |
| Tax at resident rates | SGD 375 | Money Snap calculation |
IRAS’s non-resident example (a different taxpayer)
A separate IRAS example, of a non-resident paid SGD 21,000 for three months’ work. With no reliefs to claim, the two figures are equal. Employment income is then taxed at 15% or the resident rates, whichever gives more tax.
What moves chargeable income
Five things people get wrong
- IRAS — Understanding my tax assessment — the definitions of assessable and chargeable income, and the tax-bill wording
- IRAS — Sample Income Tax calculations — the resident and non-resident worked examples
- IRAS — Tax reliefs — the SGD 80,000 Personal Income Tax Relief Cap and who may claim reliefs
- IRAS — Individual Income Tax rates — the resident rate table from YA 2024
- IRAS — Personal Income Tax Rebate — the YA 2024 and YA 2025 rebate, worked on tax payable
- IRAS — Basic guide for new individual taxpayers — who must file, and the income year behind each Year of Assessment
