Chargeable income is not your salary
Chargeable income is what remains after reliefs. Most employees can deduct CPF relief on their own contributions and earned income relief. Parents, NSmen, caregivers and those topping up CPF or contributing to SRS can claim more.

Ways to reduce the bill
- Restaurant '++' prices add a 10% service charge first, then 9% GST on the total.
- SRS and CPF top-up relief save more tax the higher your marginal rate is.
- Set aside a little each month so the tax bill is not a shock, or sign up for GIRO instalments with IRAS.
- Personal income tax relief is capped at S$80,000 a year in total.
Background
Reliefs lower chargeable income before rates apply. Common ones include earned income relief, CPF relief for employee contributions, parent and handicapped parent relief, working mother's child relief, NSman relief, course fees relief, and relief for SRS contributions and CPF cash top-ups. Total personal reliefs are capped at S$80,000 a year.
Singapore taxes individuals on income earned in Singapore, with progressive rates for residents that start at 0% on the first S$20,000 of chargeable income and rise to 24% on income above S$1 million. Tax is assessed a year in arrears: income earned in 2025 is assessed in Year of Assessment 2026.
IRAS issues a notice of assessment, usually from April onwards, and tax is due within a month, although most people opt for interest-free GIRO instalments. Estimating your bill early means you can budget for it instead of being surprised.
