Singapore levies personal income tax on individuals who earn income in or from Singapore. For foreign professionals on Employment Passes, S Passes, and other work authorisations — for a full overview of these pass types see our Complete Singapore Employment Pass Guide 2026 — understanding the Singapore personal income tax system is not optional — it directly affects take-home pay, mobility decisions, and — when a departure is planned — the employer’s legal obligations under the Form IR21 tax clearance regime. With the YA 2026 filing period having closed in April 2026 and a steady churn of EP holders triggering IR21 obligations year-round, this guide is designed as a practical reference for both individual taxpayers and the HR managers responsible for their compliance.

We cover the tax residency determination, resident and non-resident Singapore personal income tax rates for 2026, the personal reliefs and rebates available, and the IR21 tax clearance process from the employer’s perspective.

Singapore Personal Income Tax 2026: Determining Tax Residency

Whether you are taxed as a resident or a non-resident in Singapore has a significant impact on your effective tax rate. The determination rules are set by the Inland Revenue Authority of Singapore (IRAS).

You are treated as a tax resident for a Year of Assessment (YA) if you meet any of the following conditions:

  • You are a Singapore Citizen or Permanent Resident who normally resides in Singapore
  • You are a foreigner who has been physically present in or exercised employment in Singapore for at least 183 days in the preceding calendar year
  • You are a foreigner who has been in Singapore on a continuous basis straddling two calendar years, with total days of stay or employment amounting to at least 183 days (the two-year continuous-period rule)
  • You hold a valid Employment Pass or S Pass with at least one year’s validity — such pass holders are generally treated as tax residents from the date of arrival

If you do not meet these criteria — for example, if you worked in Singapore for a short assignment of less than 183 days in a single year without straddling two calendar years — you are treated as a non-resident for that year.

Singapore Income Tax Rates for Residents 2026

For YA 2026 (income earned in the calendar year 2025), Singapore tax residents are subject to progressive income tax rates. Per IRAS individual income tax rates, the progressive rate schedule runs from 0% on the first S$20,000 of chargeable income up to 24% on chargeable income above S$1,000,000. The effective tax rate for most Employment Pass holders earning between S$100,000 and S$500,000 per annum works out to approximately 11–19%, significantly below headline rates in the UK, Australia, or the US.

For YA 2026, IRAS also granted a Personal Income Tax Rebate of 60% of tax payable, capped at S$200 per taxpayer. While modest, this rebate applied to resident individuals who met the filing conditions. The rebate was part of the Budget 2026 cost-of-living relief package.

Key Features of the Resident Rate Structure

  • No capital gains tax — gains from the sale of shares, property (except for traders), or other assets are generally not taxable in Singapore
  • No inheritance, gift, or estate duty
  • Dividends from Singapore-incorporated companies are generally tax-exempt in the hands of individual shareholders (one-tier tax system)
  • Employment income includes salary, bonuses, directors’ fees, benefits-in-kind (housing allowances, car benefits, school fee reimbursements), and the value of stock options and RSU vests

Non-Resident Tax Rates for Expats

Non-residents are taxed at a flat rate on their Singapore-sourced employment income. Per IRAS, the rule is that employment income of a non-resident is taxed at the higher of:

  • 15% flat rate on gross employment income, or
  • The progressive resident rates applied to the same income

In practice, for most non-residents earning above approximately S$44,000 per year, the progressive resident rate produces a higher tax than 15%, so the progressive rate applies. Other non-employment income (director fees, consultancy fees, royalties) earned by non-residents is typically taxed at a flat 24% withholding rate.

Non-residents are not entitled to personal reliefs and rebates. This makes residency classification critically important for anyone on a short assignment in Singapore — the effective tax burden as a non-resident can be substantially higher than as a resident on the same income level.

Personal Reliefs Available to Tax Residents

Singapore’s income tax system offers a range of personal reliefs that reduce chargeable income for qualifying residents. Key reliefs for foreign professionals include:

  • Earned Income Relief: S$1,000 for those below 55; up to S$8,000 for those 60 and above
  • CPF Relief: Employee CPF contributions are deductible from chargeable income (only for Singapore Citizens and PRs — Employment Pass holders do not contribute to CPF and therefore do not qualify)
  • Course Fees Relief: Up to S$5,500 per year for approved work-related courses
  • NSman Relief: For NS-serving male citizens and PRs
  • Spouse and handicapped dependant reliefs: Available if the qualifying spouse or dependant is in Singapore and meets the income conditions
  • Qualifying Child Relief: S$4,000 per child, or more under the enhanced Working Mother’s Child Relief for female citizens and PRs

Employment Pass holders who are not Singapore Citizens or PRs do not pay CPF but may still claim a number of the above reliefs where conditions are met. The cumulative effect of reliefs can reduce chargeable income substantially, particularly for senior EP holders with children in Singapore schools.

Stock Options and RSUs: Taxable on Vest, Not on Grant

Employee equity compensation — stock options, restricted stock units (RSUs), and employee share ownership plans — is taxable in Singapore as employment income at the point of vest, not at the point of grant. The taxable amount is the open-market value of the shares at the vest date, less any amount paid by the employee to acquire them.

For internationally mobile employees who vest equity while splitting time between Singapore and another jurisdiction, the Singapore portion of the taxable benefit is apportioned based on the number of days spent in Singapore during the vesting period. This requires careful records of travel and workday allocation, particularly for executives managing multi-country roles.

Equity that vests in the hands of a departing employee after they leave Singapore — and after their IR21 tax clearance is filed — may still be taxable in Singapore if the vesting relates to a period when the individual was employed in Singapore. Employers and employees should review outstanding equity grants before the employee’s last day of Singapore employment.

IR21 Tax Clearance: Employer Obligations When a Foreign Employee Leaves

When a non-Singapore-citizen employee (including PRs) ceases employment in Singapore, leaves Singapore for more than three months, or is posted overseas for more than three months, the employer is legally required to file the Form IR21 tax clearance with IRAS. The filing deadline is at least one month before the employee’s last day of employment or departure.

Per IRAS’s Tax Clearance for Foreign & SPR Employees guidance, the employer must also:

  1. Withhold all monies due to the employee from the date of the IR21 filing until IRAS issues a Tax Clearance Directive — this includes final salary, bonus, commission, leave encashment, any gratuity, RSU vests scheduled for the departure period, and ex-gratia payments
  2. Await the IRAS Directive before releasing any withheld amounts to the employee. If a Directive to Pay (i.e. there is a tax liability) is issued, payment to IRAS must be made within 10 working days
  3. Comply with penalties for non-compliance: Employers who release monies to the employee before clearance are personally liable for the employee’s outstanding tax. Late filing of IR21 attracts a fine of up to S$5,000

What IR21 Must Cover

The IR21 form requires the employer to declare all income received by the employee from 1 January of the year of departure (or from the start of the tax year if the employee started during the year) up to the last day of employment, including:

  • Gross salary, overtime pay, and allowances
  • Bonuses (including any discretionary bonus provisionally estimated if the actual amount is not yet known)
  • Leave pay (encashment of accrued annual leave)
  • Benefits-in-kind (company car, housing allowance, club memberships, school fees reimbursed)
  • RSU vests and stock option exercises during the employment period
  • Repatriation allowances (only if not specifically excluded by IRAS guidance)

Tax Treaties: Avoiding Double Taxation

Singapore has an extensive network of Double Taxation Avoidance Agreements (DTAAs). These treaties ensure that employment income earned in Singapore by a resident of the treaty country is not taxed twice — once in Singapore and once in the home country. Major source countries for EP holders each have treaty arrangements:

  • United Kingdom: DTAA in force; Singapore-source employment income is typically taxable only in Singapore for UK residents working in Singapore
  • Australia: DTAA in force; Australian tax residents working in Singapore under the 183-day rule may claim a foreign income tax offset in Australia for Singapore taxes paid
  • India: DTAA in force; Indian nationals working in Singapore on EP are generally taxable only in Singapore on their Singapore-source employment income, subject to residency qualification
  • United States: The US–Singapore DTAA has limitations; US citizens are taxed on worldwide income by the IRS regardless of DTAA — an important consideration for US-citizen Employment Pass holders who are also considering Singapore citizenship in 2026, and the Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credit mechanisms are the primary tools for avoiding double taxation

EP holders with complex multi-jurisdiction situations — particularly those receiving equity compensation, managing investments in their home country, or with dependent family members earning income elsewhere — should seek specialist tax advice. Raffles Corporate Services works with Singapore-qualified tax advisers and can provide referrals where needed.

Filing Obligations and Deadlines

For YA 2026 (income earned in 2025), the e-filing window ran from 1 March 2026 to 18 April 2026. Employees whose income is subject to the Auto-Inclusion Scheme (AIS) — the default for most EP employers with five or more employees; for CPF rates and payroll deadlines, see the Singapore Payroll and CPF Guide 2026 from Singapore Secretary Services — have their employment income automatically included in their tax assessment and may not need to file a return at all unless they have additional income to declare or wish to claim reliefs.

Foreign professionals who arrived in Singapore during 2025 and have not yet filed should check whether they are required to file based on their income level (the filing threshold is typically income above S$22,000 per year, or any amount if there is a tax liability).

Conclusion

Singapore’s personal income tax system is competitive by global standards — progressive rates capped at 24%, no capital gains tax, and a strong treaty network. For Employment Pass holders, the key compliance obligations are understanding your residency classification, declaring equity compensation correctly at vest, and ensuring your employer handles the IR21 process properly when you depart.

HR managers and employers with foreign staff should also be aware of the Local Qualifying Salary increase to S$1,800 from 1 July 2026, which affects quota calculations for S Pass and Work Permit holders. Additionally, maintain a rolling IR21 calendar — tracking expected departure dates and flagging equity vest schedules — to avoid the personal liability exposure that comes from failing to withhold or file on time.
