With one of the most efficient tax systems in the world, Singapore offers a streamlined and transparent process. However, understanding the deadlines, necessary documentation, and available reliefs can make a significant difference in ensuring accurate filings and avoiding penalties.
In this guide, we’ll walk you through everything you need to know about how to file individual income tax in Singapore, from who needs to file, how to register with IRAS, key deadlines, what documents are required, common mistakes to avoid, and how a service like Ease to Compliance can help you stay compliant.
Understanding Individual Income Tax in Singapore
What Is Individual Income Tax?
Individual income tax in Singapore is levied on the income earned by individuals based on a progressive tax rate system. This means that higher income levels are taxed at higher rates, ranging from 0% to 22% for resident individuals.
Singapore practices a territorial tax system, meaning individuals are generally taxed on income earned in Singapore. Foreign-sourced income is taxed only if it is received in Singapore under certain circumstances.
Who Needs to File an Individual Tax Return in Singapore?
You are required to file an individual tax return in Singapore if:
- You are a resident individual who earned income in Singapore.
- You are a non-resident individual who worked in Singapore for more than 60 days.
- You received rental income, director’s fees, or income from investments.
- You were self-employed or ran a sole proprietorship or partnership.
- You received notice from the Inland Revenue Authority of Singapore (IRAS) instructing you to file.
Even if you didn’t receive a notification but earned taxable income, it is still your duty to file a return.
How to File Your Individual Income Tax in Singapore
Step 1: Determine Your Tax Residency Status
The first step in filing your individual income tax is determining whether you are considered a tax resident or non-resident.
- Resident: If you are a Singapore Citizen, Permanent Resident, or a foreigner who has stayed/worked in Singapore for at least 183 days in the previous year.
- Non-Resident: If you stayed in Singapore for less than 183 days.
Tax rates and reliefs differ for residents and non-residents, so it’s essential to confirm this before proceeding.
Step 2: Receive Your Filing Notification
Every year, IRAS sends out a filing notification letter or SMS between February and March. This notification will tell you whether you need to file a tax return manually or if you qualify for the No-Filing Service (NFS).
If you receive this notification, you are required to file by April 15 (paper) or April 18 (e-filing).
Step 3: Gather Required Information and Documents
To file accurately, prepare the following:
- Income statements (from employment, rental, freelance work, etc.)
- CPF contribution statements
- Business income records if self-employed
- Details of dependents for claiming relief
- Donation receipts, insurance premiums, or educational expenses for applicable deductions
Step 4: File Your Tax Return
Filing is done via the IRAS MyTax Portal.
E-Filing Process:
- Visit IRAS MyTax Portal
- Login using your Singpass
- Select “Individuals” > “File Income Tax Return”
- Review the auto-included income information
- Declare other income (rental, freelance, dividends, etc.)
- Claim applicable reliefs and deductions
- Submit your return
After submission, you’ll receive an acknowledgment from IRAS.
Step 5: Wait for Your Notice of Assessment (NOA)
IRAS typically sends your Notice of Assessment (NOA) between May and September. This document outlines your total tax payable or any refund due.
If you disagree with the assessment, you must file an objection within 30 days from the date of the NOA.
Important Deadlines
| Activity | Deadline |
|---|---|
| Filing Notification Sent | Feb - Mar |
| Paper Filing Deadline | 15 April |
| E-Filing Deadline | 18 April |

Missing these deadlines can result in penalties and interest.
