How to Use the Singapore Income Tax Calculator
The Singapore Income Tax Calculator computes income tax under IRAS rules and CPF (Central Provident Fund) contributions for the Year of Assessment 2025. Singapore has low, flat-structured income tax rates with a generous set of personal reliefs that significantly reduce effective tax rates.
Enter your annual employment income and residency status (tax resident, non-resident, or EP holder). The calculator applies the resident tax rates for YA 2025, deducts personal reliefs (earned income relief, NSman relief, etc.) and shows your chargeable income, tax payable, and effective tax rate.
A crucial nuance is CPF: Singapore Citizens and Permanent Residents contribute to CPF (up to 20% employee + 17% employer). This is not income tax but a mandatory savings scheme for housing, healthcare, and retirement. CPF contributions are not tax-deductible but reduce your actual net pay. Employment Pass holders (expats) do not contribute to CPF.

What is CPF and how much do I contribute?
CPF (Central Provident Fund) is Singapore's mandatory savings system for citizens and PRs. Employee contribution rates depend on age: below 55, employees contribute 20% and employers 17% of ordinary wages, up to the monthly ordinary wage ceiling (SGD $6,800 in 2025). CPF goes into Ordinary, Special, and MediSave accounts for housing, retirement, and healthcare.
Do foreigners pay CPF in Singapore?
Employment Pass (EP) and S Pass holders (foreigners) do not contribute to CPF. Permanent Residents do contribute to CPF from the date they receive PR status (at reduced rates for the first two years). This makes EP holders' effective take-home pay higher than PRs and citizens at the same gross salary.
What tax reliefs are available in Singapore?
Common reliefs: Earned Income Relief (up to $8,000 for those aged 55+), NSman (National Service) Relief, Parent Relief, Handicapped Parent Relief, Course Fees Relief (up to $5,500), CPF cash top-up relief, and SRS (Supplementary Retirement Scheme) contributions. The total personal income tax relief is capped at SGD $80,000 per YA.
Is Singapore a tax-free country for foreigners?
No — Singapore has income tax, but rates are comparatively low with a maximum of 22%. Foreign-sourced income remitted to Singapore is generally exempt from tax (territorial taxation). Singapore doesn't tax capital gains or dividends, making it very attractive for investors and high-net-worth individuals who receive investment income.
