What does a salary income tax calculation tell me?

Estimates a resident employee's annual income tax from monthly salary and bonus, allowing for CPF relief and earned income relief.

What is the formula?

Chargeable income = annual gross − employee CPF (relief capped at S$37,740) − earned income relief (S$1,000 below 55). Tax then follows the resident rate bands.

What do I need to enter?

Monthly salary (S$), Annual bonus (S$), Age (years).

Is this the same as my IRAS bill?

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.

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.

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.
