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.
- Keep receipts and records for at least five years in case IRAS asks for them.
- SRS and CPF top-up relief save more tax the higher your marginal rate is.
- Chargeable income is income after reliefs, so claim every relief you qualify for before working out the tax.
Background
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.
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.
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.
