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.
The Goods and Services Tax rose from 8% to 9% on 1 January 2024. Businesses with taxable turnover above S$1 million must register, and GST-registered retailers must quote prices to consumers inclusive of GST, so most shelf prices already include it.
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.
Tips
- GST-registered businesses must show prices inclusive of GST to consumers, so a listed retail price already includes the 9%.
- Set aside a little each month so the tax bill is not a shock, or sign up for GIRO instalments with IRAS.
- Chargeable income is income after reliefs, so claim every relief you qualify for before working out the tax.
