Singapore Personal Income Tax 2026: Your Ultimate Filing Guide

It’s that time of year again! Whether you’re a first-time filer or a seasoned taxpayer, keeping up with the Inland Revenue Authority of Singapore (IRAS) requirements is key to a smooth April. This year, there are a few updates to progressivity and reliefs you should keep on your radar.

1. Mark Your Calendars: Key Deadlines

Don't let the dates sneak up on you. Missing the deadline can result in late filing penalties of up to $5,000.

• 1 March 2026: e-Filing season officially opens.

• 15 April 2026: Deadline for paper filing (if you aren't using the portal).

• 18 April 2026: Deadline for e-Filing via myTax Portal.

2. Understanding Singapore’s Personal Income Tax System

Singapore uses a progressive tax system, meaning higher income is taxed at higher rates. Only income earned in Singapore is taxable for most individuals, and there is no capital gains tax.

Key principles:

• Tax year = Year of Assessment (YA)

  YA refers to income earned in the previous calendar year.

• Example:

  YA 2026 → Income earned from 1 Jan 2025 to 31 Dec 2025

3. Who Needs to File?

You are generally required to file a tax return if:

1. Your total personal income in 2025 was $22,000 or more.

2. You are a self-employed person with a net business income of more than $6,000.

3. You received a notification from IRAS (letter/SMS) telling you to file, regardless of your income level.

   
   

Note on the No-Filing Service (NFS): If you received a letter/SMS saying you are on the "No-Filing Service," congrats! You don't need to do anything. Your tax bill (Notice of Assessment) will be sent based on your auto-included income and previous year's relief claims. However, you should still log in to verify the details.

4. What Income Must Be Declared?

Employment Income

• Salary and bonuses
