How to Legally Reduce Your Income Tax in Singapore (2026 Guide)
Paying taxes is inevitable, but in Singapore’s progressive tax system, there are several legitimate ways to reduce your taxable income — if you understand what’s available and plan ahead. From government reliefs to smart financial moves, these strategies can help you keep more of your hard-earned money.
Make Charitable Donations
Donations to approved charities in Singapore — known as Institutions of a Public Character (IPCs) — are tax-deductible. For every dollar donated, you can usually claim more than a dollar in deductions (often 250% of the amount). This not only supports good causes but meaningfully lowers your chargeable income.
Top Up Your CPF or SRS Account
Voluntary contributions to your Central Provident Fund (CPF) — including to your Special or Medisave accounts — can reduce taxable income, especially if you’re under 55. There are caps, but planning your contributions before year-end can significantly lower what you owe. Similarly, Supplementary Retirement Scheme (SRS) contributions also offer tax deductions and boost retirement savings simultaneously.
Life Insurance Relief
You may be eligible for Life Insurance Relief if your total voluntary and compulsory CPF/Medisave contributions are below a certain threshold. In those cases, you can claim either the difference up to that amount or a percentage of the life insurance premium paid — subject to eligibility rules.
Claim Legitimate Work-Related or Business Expenses
If you’re self-employed or run a business, many business costs — such as professional fees, advertising, and allowable overheads — can be claimed as deductions against income, as long as they were incurred wholly and exclusively for work purposes. Keep proper documentation to support your claims.
Deduct Rental Costs
If you earn rental income from property, you can deduct allowable expenses (e.g., maintenance, insurance, agent fees) before arriving at net taxable rental income, which reduces your overall tax burden.
Why Planning Matters
Singapore has a personal income tax relief cap (e.g., around S$80,000), meaning that even if you qualify for multiple reliefs, the total you can claim may be limited. That’s why early planning during the calendar year — not just at tax filing time — is essential to maximise your savings.
