Estimate your monthly take-home pay after employee CPF. In Singapore income tax is filed annually (not deducted monthly), so it is shown separately as an annual estimate.
Take-home pay is your gross salary minus your employee CPF contribution. For employees aged 55 and below, the employee share is 20% of Ordinary Wages up to the S$8,000 monthly ceiling. The employer separately contributes 17% on top of your salary — this does not reduce your take-home pay.
Unlike many countries, Singapore does not deduct income tax from each paycheck. Instead, you file once a year and IRAS issues a Notice of Assessment. The annual tax estimate here uses resident progressive rates before any reliefs (such as earned income relief, CPF relief or parent relief), which would lower the actual amount.
