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
- GST-registered businesses must show prices inclusive of GST to consumers, so a listed retail price already includes the 9%.
- Keep receipts and records for at least five years in case IRAS asks for them.
- Restaurant '++' prices add a 10% service charge first, then 9% GST on the total.
- Personal income tax relief is capped at S$80,000 a year in total.
Background
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.
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.
Tax planning in Singapore is mostly about timing and reliefs rather than complex structures. Topping up CPF, contributing to SRS and claiming every relief you qualify for can lower your marginal rate band, and the savings are larger for higher earners.
