What Is Year of Assessment (YA) 2026?
Singapore’s income tax system works on a preceding-year basis.
This means:
- Income earned during 2025
- is assessed during
- Year of Assessment (YA) 2026
For example:
Income Earned | Year of Assessment |
2025 | YA 2026 |
2026 | YA 2027 |
Who Needs to Pay Personal Income Tax?
You may be required to pay personal income tax if you are a Singapore tax resident earning income from sources such as:
- Employment
- Bonuses
- Director’s fees
- Sole proprietorship income
- Partnership income
- Rental income
- Certain overseas income that becomes taxable
Foreigners working in Singapore may also need to pay tax depending on their tax residency status.
How Singapore’s Progressive Tax System Works
Singapore uses a progressive income tax system.
This means:
- Lower income is taxed at lower rates.
- Higher income is taxed only on the portion exceeding each tax bracket.
You do not pay your highest tax rate on your entire income.
This is one of the most common misconceptions among taxpayers.
Singapore Personal Income Tax Rates (YA 2026)
The resident income tax rates for YA 2026 are:

How to Calculate Personal Income Tax
The calculation generally follows these steps.
Step 1: Determine Your Total Income
Include:
- Salary
- Bonus
- Director’s fees
- Rental income
- Business income
- Other taxable income
Example:
Income Source | Amount |
Salary | $95,000 |
Bonus | $10,000 |
Rental Income | $15,000 |
Total Income | $120,000 |
Step 2: Deduct Allowable Expenses
Some income types allow deductible expenses.
Examples include:
- Rental expenses
- Business expenses
- Approved employment expenses (where applicable)
Step 3: Deduct Personal Reliefs
Common reliefs include:
- Earned Income Relief
- CPF Relief
- Spouse Relief
- Parent Relief
- Course Fees Relief (subject to current rules)
- NSman Relief
- Donations to approved Institutions of a Public Character (IPCs)
The total amount of personal income tax relief available is subject to prevailing limits under IRAS rules.
Step 4: Determine Chargeable Income
Chargeable Income = Assessable Income − Tax Reliefs
The resulting figure is what the progressive tax rates apply to.
Example Tax Calculation
Assume:
Item | Amount |
Salary | $90,000 |
Bonus | $10,000 |
Total Income | $100,000 |
CPF Relief | $20,000 |
Other Reliefs | $5,000 |
Chargeable Income | $75,000 |
The tax payable is calculated progressively across the applicable tax bands, rather than applying a single rate to the full $75,000.

Common Mistakes When Estimating Income Tax
Many taxpayers make avoidable errors when estimating their tax liability.
Assuming the Highest Tax Rate Applies to All Income
Only income within each tax bracket is taxed at that bracket’s rate.
Forgetting Bonuses
Annual bonuses increase taxable income.
Ignoring Rental Income
Rental income is generally taxable after allowable deductions.
Missing Tax Reliefs
Eligible reliefs can significantly reduce your chargeable income.
Using Outdated Tax Rates
Always ensure you are using the correct rates for the relevant Year of Assessment.
Tips to Reduce Your Tax Legally
While tax cannot always be avoided, good planning can help minimise your liability within the law.
Consider:
- Claiming all eligible tax reliefs.
- Maintaining proper records.
- Making qualifying charitable donations.
- Reviewing deductible expenses for rental or business income.
- Filing your tax return accurately and on time.
If your financial affairs are more complex, professional tax advice may help ensure compliance while identifying legitimate tax-saving opportunities.
Checklist Before Calculating Your Tax
Before using a personal income tax calculator, gather:
- Employment income records
- Bonus details
- Rental income information (if applicable)
- Business income records (if self-employed)
- CPF contribution details
- Information on eligible tax reliefs
- Records of approved charitable donations
Having these details ready will help you produce a more accurate estimate.
Summary
A Singapore Personal Income Tax Calculator (YA 2026) is a practical tool for estimating your tax liability before filing your annual tax return. By understanding how chargeable income is determined, how Singapore’s progressive tax rates work, and which tax reliefs you may qualify for, you can better manage your finances and avoid surprises when your tax assessment is issued.
