IRAS Income Tax Calculator 2026: How to Use & Calculate Tax in Singapore

If you’re living or working in Singapore, tax season brings one big question: how much do I actually owe? The IRAS income tax calculator takes the guesswork out of that estimate by turning your income and reliefs into a clear number. In this guide, we’ll walk through using the official tool for Year of Assessment 2026, with real examples and the tax brackets you need to know.

Maximum marginal tax rate for residents (YA 2026): 24% · Tax-free threshold for residents: First SGD 20,000 · Number of resident tax brackets (YA 2026): 12 · Non-resident tax rate (flat): 24% (or 15% at option for certain income)

What is the Income Tax bracket in Singapore 2026?

Resident tax rates for Year of Assessment 2026

Singapore uses a progressive tax system for residents. For YA 2026, the rates range from 0% on the first SGD 20,000 to 24% on income above SGD 1,000,000. There are 12 brackets in total, according to IRAS (Singapore’s tax authority). The table below shows the key brackets:

The pattern: the first SGD 20,000 is completely tax-free, then the rate climbs quickly in the early brackets to 7% by SGD 40,000. For a typical salaried employee earning SGD 60,000, only SGD 40,000 is chargeable after the first SGD 20,000 exemption — the effective rate stays low.

Non-resident tax rates and withholding tax

Non-residents are taxed at a flat rate of 24% on all Singapore-sourced income, as confirmed by IRAS (Singapore’s tax authority). However, for certain rental income or income subject to withholding tax, the rate may be 15% at the option of the non-resident. Unlike residents, non-residents do not benefit from the SGD 20,000 tax-free threshold. The implication: a non-resident earning SGD 60,000 would owe 24% on the full amount — SGD 14,400 — compared to a resident paying roughly SGD 2,650 on the same gross income after reliefs.

How should I calculate my Income Tax?

Using the official IRAS income tax calculator (XLSM file)

IRAS provides a free downloadable Microsoft Excel workbook with macros (.xlsm) that automatically computes your tax. The tool is updated each year with the latest brackets and reliefs. IRAS (Singapore’s tax authority) notes that the calculator requires you to enable macros — a security step that allows the formulas to run.

Manual calculation with tax bracket table

You can also compute tax by hand using the brackets above. The formula: subtract the tax-free portion, then apply each marginal rate to the remaining slices of income. For example, a chargeable income of SGD 50,000: first SGD 20,000 at 0%, next SGD 10,000 at 2% (SGD 200), next SGD 10,000 at 3.5% (SGD 350), final SGD 10,000 at 7% (SGD 700) — total SGD 1,250.

Step-by-step example for a resident earning SGD 60,000

• Gross annual income: SGD 60,000
• Employee CPF contribution (20%): SGD 12,000
• Chargeable income after CPF: SGD 48,000
• Tax-free threshold: SGD 20,000 (0%)
• Tax on next SGD 10,000 at 2%: SGD 200
• Tax on next SGD 10,000 at 3.5%: SGD 350
• Tax on next SGD 8,000 at 7%: SGD 560
• Total tax before reliefs: SGD 1,110

Actual liability can be lower because personal reliefs like earned income relief or course fees reduce chargeable income further. The IRAS basic guide (official guidance) explains that taxpayers can adjust reliefs during e-filing.

What is the maximum I can earn without paying income tax?

Tax exemption threshold for residents

Residents pay no tax on the first SGD 20,000 of chargeable income. But the effective tax-free amount can be much higher once personal reliefs are applied. According to IRAS (Singapore’s tax authority), the general filing threshold is total income above SGD 22,000 — meaning someone earning exactly SGD 22,000 likely owes no tax.

Impact of personal reliefs on the effective tax-free amount

• Earned income relief: SGD 1,000 (age below 55) to SGD 8,000 (age 60+), automatically granted
• CPF relief: full employee contribution (up to SGD 20,600 for 2025)
• Course fees, life insurance, and other deductions

Example: earning SGD 25,000 with no other income

• Gross: SGD 25,000
• Employee CPF (20%): SGD 5,000 → chargeable income: SGD 20,000
• First SGD 20,000 at 0% → tax = SGD 0

The catch: non-residents get no tax-free threshold, so even SGD 1 of Singapore-sourced income attracts the 24% flat rate.

How much tax will I pay if I earn 40k?

Tax calculation for gross annual income of SGD 40,000

• Gross: SGD 40,000
• Employee CPF (20%): SGD 8,000
• Chargeable income: SGD 32,000
• Tax-free first SGD 20,000: SGD 0
• Next SGD 10,000 at 2%: SGD 200
• Next SGD 2,000 at 3.5%: SGD 70
• Total tax: SGD 270

That is the base. After personal reliefs (e.g., earned income relief of SGD 1,000), chargeable income drops to SGD 31,000, reducing tax to about SGD 235. The IRAS basic guide (official guidance) reminds taxpayers to claim all eligible reliefs via the online filing form.

What income is not taxed in Singapore?

List of tax-exempt income for individuals

• Capital gains – not taxed, as confirmed by IRAS (Singapore’s tax authority)
• Foreign-sourced income remitted to Singapore – may be exempt under the territorial tax system, subject to conditions
• Individual dividends from Singapore companies – tax-exempt under the one-tier corporate tax system
• Interest from approved Singapore banks – tax-exempt for individuals

What this means: Singapore taxes only income earned in or derived from Singapore, with no capital gains tax — a major advantage for investors.

Step-by-Step Guide to Using the IRAS Income Tax Calculator

1. Download the calculator from the IRAS e‑filing page (official site). Look for the “Tax Calculator” download under the Individual Income Tax section.
2. Enable macros when you open the file. In Excel, click “Enable Content” if prompted. The calculator will not work without macros enabled.
3. Fill in your personal details: Name, NRIC/FIN (optional), Year of Assessment (2026), and residency status.
4. Enter your income: Use the tabs provided – Employment Income, Trade Income, Other Income. IRAS pre‑fills employment income for employers under the Auto‑Inclusion Scheme, but you must verify all entries against your payslip or Form IR8A.
5. Enter CPF contributions: The calculator may pre‑fill this if you use the auto‑inclusion version; otherwise enter your total employee CPF for the year.
6. Claim your personal reliefs: In the relevant section, add earned income relief (automatic for residents), course fees, life insurance, CPF top‑ups, and other deductions. The calculator reduces chargeable income immediately.
7. Review the summary sheet: The calculator shows total income, total reliefs, chargeable income, tax before reliefs, and final tax payable. Adjust any figures until everything matches your actual records.
8. Save or print the result. Use this estimate to plan your tax payment or to check against the Notice of Assessment you will receive after filing.

The IRAS calculator runs offline once downloaded – no internet connection required after the file is saved.
