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
- Non-residents cannot claim personal reliefs, which is why their effective rate is usually higher.
- Set aside a little each month so the tax bill is not a shock, or sign up for GIRO instalments with IRAS.
- Personal income tax relief is capped at S$80,000 a year in total.
- Restaurant '++' prices add a 10% service charge first, then 9% GST on the 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.
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.
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.
