How Singapore Income Tax Is Calculated for YA 2026

Singapore operates a progressive personal income tax system for tax residents. For Year of Assessment 2026 — covering income you earned between 1 January and 31 December 2025 — the tax rates run from 0% on your first $20,000 of chargeable income up to 24% on any amount above $320,000. Tax is calculated on your chargeable income, not your gross income, which is why understanding reliefs is so important.

The calculation works in three steps. First, you total all taxable income streams: employment salary, bonuses, rental income, freelance or director fees, and any other Singapore-source income. Second, you deduct all approved tax reliefs and deductions to arrive at your chargeable income. Third, you apply the progressive tax brackets to that chargeable income to find your tax payable.

It is critical to understand that Singapore's brackets are cumulative, not flat. If your chargeable income is $90,000, you do not pay 15% on the whole amount. You pay 0% on the first $20,000, 2% on the next $10,000, 3.5% on the following $10,000, 7% on the next $10,000, 11.5% on the next $30,000, and 15% on the remaining $10,000. Your effective tax rate — total tax divided by total income — will always be well below your marginal (top bracket) rate.

Singapore's income tax system is widely regarded as one of the most competitive in Asia. There is no capital gains tax, no inheritance tax, and no GST payable on employment income. Combined with a maximum tax rate of 24% and generous reliefs, Singapore's personal income tax burden for middle-income earners is significantly lower than comparable rates in the United Kingdom, Australia, or the United States.

Tax Reliefs That Reduce Your Chargeable Income

Singapore's tax relief system is extensive. Most tax residents qualify for at least three or four reliefs that meaningfully reduce their taxable income. The most universally applicable relief is the Earned Income Relief (EIR). If you are below age 55, you automatically receive $1,000 of EIR. From age 55 to 59, this rises to $6,000. At 60 and above, it reaches $8,000. Handicapped taxpayers receive higher relief amounts at each age band.

CPF Relief allows you to deduct your employee CPF contributions from taxable income. For employees aged 55 and below, the employee CPF contribution rate is 20% of ordinary wages, subject to the Ordinary Wage Ceiling of $6,800 per month. This means the maximum annual CPF Relief for a typical salaried employee aged below 55 is $6,800 x 12 x 20% = $16,320. Your employer's CPF contributions are not claimable — only your own employee share qualifies.

The Supplementary Retirement Scheme (SRS) is a voluntary savings scheme that gives you an immediate tax deduction on contributions. Singapore citizens and permanent residents can contribute up to $15,300 per year. Every dollar you contribute directly reduces your chargeable income, making SRS particularly valuable for higher-income taxpayers. SRS withdrawals in retirement are taxed at 50% of the prevailing rate, providing a long-term tax advantage.

NSman Relief rewards those who have completed National Service. Operationally ready NSmen receive $1,500 annually; key appointment holders receive $3,500. Wives and parents of NSmen can claim $750. Parent Relief provides $5,500 per dependent parent (or $9,000 for a handicapped parent) who lives with you and is not separately maintained. Course Fees Relief of up to $5,500 and Life Insurance Relief of up to $5,000 (where CPF contributions are below $5,000) round out the most commonly claimed reliefs.

Singapore vs Other Countries: Why the Tax Rate Is Competitive

Singapore is consistently ranked among the world's most tax-competitive jurisdictions for personal income. The top marginal rate of 24% applies only above $320,000 — a threshold that very few residents reach. By comparison, the UK's top rate is 45% from £125,140, Australia's top rate is 47% above A$180,000, and the US federal top rate is 37% above US$578,125, with additional state taxes in most states.

For middle-income earners in Singapore — those earning between $60,000 and $120,000 — the effective tax rate (after reliefs) typically falls between 4% and 9%. A Singapore resident earning SGD $80,000 with standard CPF Relief and Earned Income Relief pays around $3,000 to $4,500 in income tax per year, an effective rate of 3.7% to 5.6% on total income. This is substantially lower than the effective rates on comparable incomes in most developed economies.

Singapore also benefits from its extensive network of over 90 double taxation agreements (DTAs) with countries around the world. If you are a Singapore tax resident who receives income from a DTA partner country, you can generally claim a tax credit or exemption in Singapore for tax already paid in that country, preventing double taxation. For expatriates who maintain income streams in their home country, this network is a significant advantage.

Finally, Singapore imposes no tax on capital gains. Profits from selling shares, property (subject to the seller's stamp duty rules), or other capital assets are not taxable. Dividends from Singapore companies are generally tax-exempt at the individual level under the one-tier tax system — the company has already paid corporate tax on those profits. This makes Singapore particularly attractive for investors, entrepreneurs, and business owners who want to keep more of their returns.
