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
- Keep receipts and records for at least five years in case IRAS asks for them.
- Non-residents cannot claim personal reliefs, which is why their effective rate is usually higher.
- SRS and CPF top-up relief save more tax the higher your marginal rate is.
- GST-registered businesses must show prices inclusive of GST to consumers, so a listed retail price already includes the 9%.
Background
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.
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.
