How to use the salary income tax estimator
- Enter the monthly salary (S$).
- Enter the annual bonus (S$).
- Enter the age (years).
- The results update as you type, or press Calculate.
- Read the gross annual income first, then the supporting figures below it.
Formula
Chargeable income = annual gross − employee CPF (relief capped at S$37,740) − earned income relief (S$1,000 below 55). Tax then follows the resident rate bands.
Worked example
For example, with these inputs:
- Monthly salary (S$): 5,000
- Annual bonus (S$): 10,000
- Age (years): 30
the calculator returns:
- Gross annual income: S$70,000.00
- CPF relief: S$14,000.00
- Estimated chargeable income: S$55,000.00
- Estimated income tax: S$1,600.00
- Effective rate on gross: 2.29%
- Annual cash after CPF and tax: S$54,400.00
Good to know: Only CPF relief and earned income relief are included. Add other reliefs (parent, NSman, course fees, SRS) to lower the figure.
Background
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.
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.
