Singapore Personal Income Tax Calculator 2026: Estimate Your Tax From Income and Resident Tax Brackets
Singapore taxes resident individuals on a progressive scale that starts at 0% and now reaches 24% at the very top. Yet most wage earners never touch those upper bands, because the marginal system means you are taxed band by band, not on your whole salary at once. In this blog, we discuss how to estimate your 2026 tax using the Year of Assessment framework. We cover resident tax brackets, reliefs, rebates, non-resident rules and bookkeeping that makes your estimate faster and more accurate.
How Does a Singapore Personal Income Tax Calculator Work?
An estimator works out your tax by applying the progressive resident rates to your chargeable income, not your gross salary. The Inland Revenue Authority of Singapore (IRAS) is the statutory board that administers these tax rules and publishes the official figures used for calculations. Its published figures are the reference point for any calculation.
The process starts with assessable income. That includes your employment income, trade or professional income, and rental income. It also includes taxable investment income such as interest, but many Singapore dividends and capital gains are not taxable. Assessable income is your total income after allowable expenses and approved donations; deduct your personal reliefs from it to arrive at chargeable income, to which the tax brackets apply.
One concept matters more than any other: the Year of Assessment (YA). Income earned in calendar year 2025 is generally assessed in YA 2026, and income earned in 2026 is generally assessed in YA 2027, although business income may follow a different basis period. When you estimate your bill today, you normally project tax on income you are still earning. A reliable income tax calculator approach helps you plan ahead.
What Are the Singapore Tax Brackets for 2026?
According to IRAS, resident individuals pay progressive tax for YA 2026, with marginal rates rising from 0% to 24%. Two higher marginal rates of 23% and 24% apply to chargeable income above S$500,000 and S$1,000,000 respectively. These higher rates were introduced from YA 2024 and continue to apply for YA 2026.
Marginal means each band is taxed at its own rate. Only the portion of income inside a band is taxed at that band's rate. Your first S$20,000 of chargeable income is always taxed at 0%, no matter how much you earn in total.
Always confirm the latest rates for resident individuals on the IRAS website before finalising any estimate, because Budget announcements can adjust rates from one YA to the next.
Resident Tax Brackets for YA 2026
| Chargeable Income (S$) | Marginal Rate | Tax at Top of Band (S$) |
|---|---|---|
| 0 – 20,000 | 0% | 0 |
| 20,001 – 30,000 | 2% | 200 |
| 30,001 – 40,000 | 3.5% | 550 |
| 40,001 – 80,000 | 7% | 3,350 |
| 80,001 – 120,000 | 11.5% | 7,950 |
| 120,001 – 160,000 | 15% | 13,950 |
| 160,001 – 200,000 | 18% | 21,150 |
| 200,001 – 240,000 | 19% | 28,750 |
| 240,001 – 280,000 | 19.5% | 36,550 |
| 280,001 – 320,000 | 20% | 44,550 |
| 320,001 – 500,000 | 22% | 84,050 |
| 500,001 – 1,000,000 | 23% | 199,050 |
| Above 1,000,000 | 24% | — |
How Do You Estimate Your Tax Step by Step?
You can run a tax estimate yourself in four to five steps, using nothing more than your income records and the bracket table above. Here is the method we walk clients through when they prepare their own projections.
Step 1: Total your assessable income
Add up your salary, bonuses, trade income and rental income for the relevant basis period. Include one-off items such as annual bonuses, but tax them in the year you become entitled to them rather than necessarily the year you receive them.
Step 2: Deduct allowable expenses and reliefs
Trade, rental and employment income may allow certain deductible expenses, subject to the applicable conditions. Then apply personal reliefs such as CPF contributions, earned income relief and family reliefs, remembering the total relief cap.
Step 3: Apply the resident tax brackets
Use this calculation template: taxable amount within each band × that band’s marginal rate = tax for the band. Add the band results, then proceed to rebates or credits in the next step. This is where the progressive system rewards accurate arithmetic.
Step 4: Subtract any rebates or credits
Rebates such as the Parenthood Tax Rebate can directly reduce the tax payable. Foreign tax credits may be available to Singapore tax residents where the same income is taxed overseas and is also taxable in Singapore.
Step 5: Sanity-check the result
Compare your estimate with the official tools IRAS provides for individuals. A small variance is normal, because your final notice of assessment reflects reliefs the system applies automatically.
What Do Typical Tax Bills Look Like After the Brackets?
Worked examples make the arithmetic real. The figures below show tax on chargeable income before reliefs and rebates, based on the YA 2026 resident schedule.
Notice how the effective rate stays far below the top marginal rate. At S$100,000 of chargeable income, the effective rate is roughly 5.7%. That is the practical benefit of a marginal system, and it surprises many first-time estimators.
Worked Examples of Estimated Tax
| Chargeable Income (S$) | Estimated Tax Before Reliefs and Rebates (S$) | Effective Rate |
|---|---|---|
| 50,000 | 1,250 | 2.5% |
| 100,000 | 5,650 | 5.7% |
| 200,000 | 18,850 | 9.4% |
| 400,000 | 59,850 | 15.0% |
Which Personal Reliefs Reduce Your Chargeable Income?
Reliefs reduce chargeable income before the brackets apply, while rebates cut the final tax payable. From YA 2018 onwards, total personal reliefs are capped at S$80,000 per YA. Plan the order and mix of claims instead of chasing every minor item.
We help clients map their eligible reliefs early in the year, because the biggest savings often come from structured items such as CPF and retirement contributions rather than last-minute claims.
1. Earned income and CPF relief
Earned income relief applies to employment or trade income, up to S$1,000 for those below 55 and a higher cap from age 55. Eligible compulsory employee CPF contributions attract relief, subject to the CPF salary ceiling.
2. Family-related reliefs
Spouse relief, qualifying child relief and parent relief support taxpayers supporting dependants. Each carries its own conditions and caps, so check eligibility carefully rather than assuming.
3. Retirement and course fees
Contributions to the Supplementary Retirement Scheme (SRS) are deductible up to an annual cap. Course Fees Relief is no longer available from YA 2026, so it should not be included in tax estimates.
Common Reliefs and Their Effect
| Relief Type | What It Covers | Effect on Your Estimate |
|---|---|---|
| Earned income relief | Employment or trade income | Up to S$1,000 below age 55; higher from age 55 |
| CPF relief | Mandatory CPF contributions | Deductible subject to the CPF salary ceiling |
| SRS relief | Supplementary Retirement Scheme contributions | Deductible up to the annual cap |
| Family reliefs | Spouse, child and parent relief | Reduces chargeable income if conditions are met |
| Personal relief cap | Total of all reliefs | Capped at S$80,000 per YA from YA 2018 |
How Are Non-Residents Taxed in Singapore?
Non-residents generally pay the higher of 15% of gross employment income or the resident progressive rates on employment income. Other income, including director's fees and rental income, is generally taxed at 24%.
If you spent fewer than 183 days in Singapore during the relevant period, non-resident treatment generally applies. Personal reliefs do not apply to non-residents, although deductions for expenses and donations may be available.
Residency is determined by physical presence and other statutory tests. Confirm your status with IRAS before estimating, especially if you travel frequently for work.
When Are the Filing and Payment Deadlines?
Individuals required to file must e-file their tax return by 18 April following the end of the relevant basis period. For income earned in calendar year 2025, the YA 2026 deadline fell on 18 April 2026. If you missed it, you should still file promptly, because late filing attracts penalties and enforcement action from IRAS.
Once IRAS issues your Notice of Assessment, payment is due within 30 days. Your own projection is most useful in this window, because comparing your estimate against the notice gives you time to object if something looks wrong.
Resident Versus Non-Resident Treatment
| Aspect | Tax Resident | Non-Resident |
|---|---|---|
| Tax residency test | 183 days or more in Singapore, or other statutory criteria | Fewer than 183 days in the relevant period |
| Employment income | Progressive rates from 0% to 24% | Higher of 15% or resident progressive rates |
| Other income | Progressive resident rates | Generally a flat 24% |
| Personal reliefs | Available, subject to the S$80,000 cap | Generally not available |
| E-filing | Required once income reaches the filing threshold | Generally required on Singapore-sourced income |
