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.
You are generally a tax resident if you are a citizen or PR who normally lives here, or a foreigner who has stayed or worked in Singapore for at least 183 days in the calendar year. Non-residents do not get personal reliefs and are taxed differently, which is why residency status matters so much for expatriates.
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.
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.
Tips
- Non-residents cannot claim personal reliefs, which is why their effective rate is usually higher.
- Chargeable income is income after reliefs, so claim every relief you qualify for before working out the tax.
- Set aside a little each month so the tax bill is not a shock, or sign up for GIRO instalments with IRAS.
