How these were worked out
Tax is charged band by band: the first S$20,000 at 0%, the next S$10,000 at 2%, the next S$10,000 at 3.5%, then 7%, 11.5%, 15%, 18%, 19%, 19.5%, 20%, 22%, 23% and 24% above S$1 million.
Singapore's tax system is simple by global standards, but the progressive bands, reliefs and the 9% GST still trip people up. A quick calculation helps you set aside the right amount before IRAS sends your notice of assessment, or check that a bill has been worked out correctly.
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.
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.
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.
Tips
- Keep receipts and records for at least five years in case IRAS asks for them.
- GST-registered businesses must show prices inclusive of GST to consumers, so a listed retail price already includes the 9%.
- Personal income tax relief is capped at S$80,000 a year in total.
