Singapore’s tax system is known for its simplicity and efficiency. Individual income tax is based on a territorial basis, meaning only income earned in Singapore or received from overseas is taxable. To help taxpayers navigate the system, this guide explains how Singapore’s individual income tax works and highlights common pitfalls to avoid.
How Individual Income Tax Works in Singapore
1. Tax Residency Status
Singapore residents and non-residents are taxed differently:
- Tax Residents: Individuals who stay in Singapore for at least 183 days in a calendar year, or those with a permanent home in Singapore, are considered tax residents. They enjoy progressive tax rates and tax reliefs.
- Non-Residents: Individuals who stay in Singapore for less than 183 days are taxed at a flat rate of 15% or the progressive resident rates, whichever results in a higher tax amount. Employment income of non-residents is subject to withholding tax in some cases.
2. Progressive Tax Rates
Singapore follows a progressive tax rate system, meaning the more you earn, the higher your tax rate. As of YA 2024, the tax rates range from 0% to 24%. The first $20,000 of chargeable income is tax-free, and tax rates increase gradually for higher income brackets.

3. Taxable and Non-Taxable Income
- Taxable Income: Includes salaries, bonuses, director’s fees, rental income, and income from self-employment.
- Non-Taxable Income: Capital gains, lottery winnings, and overseas income (unless received in Singapore under specific conditions).
4. Tax Reliefs and Deductions
Taxpayers can claim various reliefs to reduce their taxable income, including:
- CPF Contributions (for employed individuals)
- Course Fees Relief (for work-related training)
- Parent Relief & Child Relief (for supporting dependents)
- Life Insurance Relief (if CPF contributions are below $5,000)
5. Filing and Payment Deadlines
- E-Filing Deadline: 18 April each year
- Paper Filing Deadline: 15 April each year
- Tax Payment: IRAS issues tax bills (Notice of Assessment) between May and September, with payment due within one month.
Common Pitfalls to Avoid
1. Failing to Declare All Income
Some taxpayers forget to declare all sources of income, such as rental income from properties or freelance earnings. IRAS has robust data-matching tools to detect undeclared income, and penalties for non-compliance can be severe.
2. Incorrectly Claiming Deductions and Reliefs
While tax reliefs help reduce taxable income, incorrectly claiming them (e.g., overstating business expenses or CPF contributions) can result in penalties. Ensure all claims are valid and supported by documentation.
3. Late or Non-Filing of Tax Returns
Missing the filing deadline can lead to fines or summons. If you fail to file for consecutive years, IRAS may issue an estimated tax bill, which could be higher than your actual tax liability.
4. Misunderstanding Tax Residency Rules
Taxpayers who travel frequently may mistakenly assume they qualify for tax residency when they do not. If your stay falls short of 183 days, you may be taxed as a non-resident at a higher rate.
5. Overlooking Employer-Related Taxes
Expats and employees with employer-provided benefits (e.g., housing allowances) should be aware that these perks are taxable. Employers must also file IR8A forms for employees annually to report income details.
Ignoring Tax Notices and Correspondence from IRAS1
Ignoring tax notices or failing to respond to IRAS queries can lead to unnecessary penalties and legal action. Always update your contact details and review tax statements carefully.
