Personal Income Tax Filing in Singapore: A Guide for Residents and Foreigners

Last Updated: June 2026

You must file personal income tax in Singapore if your total income for the preceding year was more than S$22,000, or if you are self-employed with net profit over S$6,000, or if you are a non-resident who earned income here. Tax residents pay progressive rates from 0% to 24%, non-residents face flat treatment, and the e-filing window runs from 1 March to 18 April through the IRAS myTax Portal.

This guide covers who must file, residency and the 183-day rule, resident versus non-resident rates, the reliefs that lower your bill, how to file, the penalties, and tax clearance for foreigners leaving the country.

Key Takeaways

• You file if total income exceeds S$22,000, or self-employment net profit exceeds S$6,000, or you are a non-resident with Singapore income.
• Residents pay progressive rates: the first S$20,000 is 0%, rising to a top rate of 24% above S$1,000,000 (from YA 2024).
• Residency follows the 183-day rule: a foreigner here for 183 days or more in the year is a tax resident.
• Non-resident employment income is taxed at 15% or resident rates, whichever is higher; most other income is generally 24%.
• The e-filing window is 1 March to 18 April; many taxpayers are on the No-Filing Service and only verify their return.
• A foreigner ceasing employment must clear tax before leaving, with the employer filing Form IR21.

Who Must File Personal Income Tax in Singapore?

You must submit a return if any of the following applied in the preceding calendar year, per the IRAS guidance on individuals required to file:

• Your total annual income was more than S$22,000.
• You were self-employed (sole proprietor, freelancer, or commission agent) with net profit over S$6,000.
• You are a non-resident who earned income in Singapore, other than exempt income.
• IRAS sent you a filing notification, in which case you must file even below the thresholds.

Income here is wide: salary, bonuses, director’s fees, rental income, and trade profits. If your only income is employment income under the Auto-Inclusion Scheme, the figures reach IRAS directly, but you still check the return. Business owners taking both a salary and dividends should read our guide on director salary versus dividends, which affects your tax and CPF.

How Is Tax Residency Determined in Singapore?

Your residency, not your nationality, decides how much tax you pay. Under the IRAS tax residency rules, you are a tax resident if you are:

• A Singapore citizen or permanent resident who normally resides in Singapore, or
• A foreigner who stayed or worked in Singapore for 183 days or more during the preceding year.

The 183-day rule matters most for foreign professionals. Cross the mark and you are taxed as a resident, with progressive rates and reliefs; stay under it and you are a non-resident under the flat rules below. Concessions exist for employment straddling two years, so confirm your day count if you arrived or left mid-year. If you are moving here to set up a business, our guides on opening a business in Singapore as a foreigner and work passes for foreign professionals cover the wider picture.

What Is the Personal Income Tax Rate in Singapore?

Singapore uses a progressive resident system, so you pay the higher rate only on the slice of income in each band. The first S$20,000 of chargeable income is taxed at 0%, the next band at 2%, and the rate steps up to a top marginal rate of 24% on income above S$1,000,000, as published in the IRAS individual income tax rates (from YA 2024).

The chart below shows the marginal rate by band.

Because the system is marginal, your effective rate is always lower than your top band, and reliefs cut your chargeable income before these rates apply.

How Are Foreigners and Non-Residents Taxed?

If you stayed or worked here for fewer than 183 days, you are a non-resident. Non-resident employment income is taxed at a flat 15%, or at resident rates, whichever is higher. Director’s fees, consultancy income, and most other non-resident income are generally taxed at 24%, with no reliefs. The full breakdown sits on the IRAS basics of individual income tax pages.

So crossing the 183-day threshold usually means a lower bill: a one-year posting often makes you a resident, while a short stint often does not. Owners of foreign-owned companies should also read tax filing for foreign-owned companies, since the two positions interact.

Tax Clearance When a Foreigner Leaves

If you are a foreigner ceasing employment, taking an overseas posting over three months, or leaving for good, your employer must seek tax clearance by filing Form IR21 and withhold your final payments until IRAS issues a directive. Plan for this before your last day.

When Is the Personal Income Tax Filing Deadline?

The filing season opens on 1 March, when the myTax Portal and pre-filled returns become available, and the e-file deadline is 18 April. IRAS pre-fills returns from employer and bank data, and places many taxpayers on the No-Filing Service, where no action is needed if the details are correct.

Even so, log in and check: the pre-filled figures are only as good as what was reported to IRAS, and reliefs such as course fees or donations may not be captured.

What Reliefs and Deductions Can Lower Your Tax?

Reliefs cut your chargeable income before the rates apply, subject to a personal income tax relief cap of S$80,000 per Year of Assessment. Common reliefs include:

• Earned Income Relief, given automatically on employment, trade, or pension income.
• CPF relief on your own mandatory and voluntary contributions, within limits.
• Spouse, child, and parent reliefs for dependants who meet the conditions.
• Course Fees Relief for approved skills upgrading.
• SRS contributions and qualifying donations, where donations attract a 250% deduction.

Deductions for allowable employment or rental expenses work the same way; keep records for at least five years. If you also run a company, our overview of accounting and compliance in Singapore and the YA 2026 tax guide explain how the corporate side fits together.

How Do I File My Personal Income Tax?

Filing is done online through the myTax Portal:

• Log in to myTax Portal with your Singpass.
• Open the return for the current Year of Assessment and review the pre-filled income.
• Add any income not shown, such as rental or freelance income, and claim your reliefs and deductions.
• Check the computed tax, then submit and save the acknowledgement.

IRAS then issues a Notice of Assessment showing the tax payable, settled by GIRO or a one-time payment. If your situation is complex (multiple income sources, recent migration, or directorships across several companies), professional help avoids costly errors. The same discipline applies to business filings, from registering a company to meeting the GST registration threshold and managing Section 45 withholding tax on cross-border payments.

What Are the Penalties for Late or No Filing?

Missing the 18 April deadline has consequences. IRAS may issue an estimated Notice of Assessment from available data, which you must pay until you file and it is corrected. Late filing can attract a penalty, and continued non-compliance a summons or court fine, so filing on time, even a nil return, is always cheaper.
