Singapore – Taxation

How does the tax system in Singapore work?

Singapore’s tax framework is administered at the national level by the Inland Revenue Authority of Singapore (IRAS), with no sub-national or regional income taxes layered on top. The country applies a territorial principle: individuals are taxed only on income that arises in or is derived from Singapore. For expats who earn from multiple countries, this is a considerable advantage compared with worldwide tax regimes.

Foreign-sourced income received in Singapore by individuals is generally exempt from tax, subject to conditions and exclusions set out in the Income Tax Act — provided it is not channelled through a Singapore partnership and does not arise from a trade or business conducted within Singapore. This territorial approach distinguishes Singapore from jurisdictions that impose tax on all global income regardless of where it originates.

Singapore operates on a preceding-year basis of assessment: income earned during calendar year 2025 is assessed in Year of Assessment (YA) 2026. Rather than real-time deductions applied throughout the year, the system works through a formal annual assessment cycle, giving taxpayers a defined point at which their tax position is calculated and confirmed.

Your tax residency classification is the single most consequential factor shaping how your income is taxed. Foreigners are regarded as tax residents if they have stayed or worked in Singapore for more than 183 days in a calendar year in the previous Year of Assessment, or if they have been in Singapore continuously for three consecutive years, or have been employed there for a continuous period spanning two calendar years with a combined duration exceeding 183 days.

Foreigners holding a work pass valid for at least one year are also treated as tax residents. However, this classification is reviewed at the point of tax clearance when employment ends, in accordance with prevailing residency rules. Always refer to the IRAS tax residency page for the latest guidance, as administrative concessions can affect your status.

Tax resident individuals in Singapore are subject to a graduated rate structure, with higher earners paying a larger share. As of 2025, rates begin at 0% on the first S$20,000 of taxable income and rise progressively to 24% on income exceeding S$1,000,000.

Does Singapore have double taxation agreements, and how do they affect expats?

Singapore has concluded Avoidance of Double Taxation Agreements (DTAs), limited DTAs, and Exchange of Information Arrangements with roughly 100 jurisdictions. This treaty network is one of the broadest in Asia and offers meaningful protections for internationally mobile individuals.

A DTA between Singapore and another jurisdiction can reduce or eliminate tax on particular categories of income earned in one country by a resident of the other. In practical terms, where the same income would otherwise be taxed in two countries, a DTA can either exempt it in one jurisdiction or allow a credit for the tax already paid elsewhere — preventing the same earnings from being taxed twice over.

If you are a tax resident of a jurisdiction that has signed a DTA with Singapore, you may be shielded from double taxation on the same income. Singapore tax residents can also claim DTA benefits entitling them to reduced withholding tax rates or exemptions in the other country. To access these benefits, you will need to present a Certificate of Residence (COR) to the foreign tax authority — a formal letter from IRAS confirming your Singapore tax residency for the purpose of DTA claims.

Where overseas taxes are only partially reduced by a DTA, foreign tax credits may apply. There are two forms: Double Tax Relief (DTR) allows Singapore tax residents to offset foreign taxes paid on income also taxable in Singapore, where the relevant DTA permits it. A Unilateral Tax Credit (UTC) is available to Singapore tax residents earning income from countries without a DTA, subject to IRAS conditions.

The full and current list of Singapore’s DTA partners is available on the IRAS DTA database, where agreements can be downloaded and filtered by jurisdiction and status. Bear in mind that agreements which have been signed but not yet ratified do not carry the force of law.

Singapore does not hold comprehensive income tax treaties with every country. Expats from jurisdictions without a DTA should seek professional advice to understand their exposure to double taxation and what mitigation options are available to them.

What taxes do expats need to pay in Singapore?

Singapore’s tax environment is considerably less complex than that of many developed economies. There is no capital gains tax, no inheritance tax, no wealth or net worth tax, and no gift tax. The main taxes expats are likely to encounter are outlined below.

Income Tax

Tax residents benefit from personal reliefs and deductions and are taxed at graduated rates running from 0% to 24%. Non-residents receive no personal reliefs or deductions and are subject to a flat rate of 24%. As a concession, employment income of non-residents is taxed at whichever is higher: a flat 15% or the graduated resident rates with personal reliefs.

As a broad guide for residents (as of YA 2025), the first S$20,000 of chargeable income is taxed at 0%, rising progressively through the brackets to 23% on chargeable income between S$500,000 and S$1 million, and 24% on income above S$1 million. Always check the current bracket table with IRAS, as rates are subject to change.

Goods and Services Tax (GST)

From 1 January 2024, Singapore’s GST rate stands at 9%, covering most domestically supplied goods and services, as well as imported goods and certain digital services. GST is a consumption tax collected by registered businesses on behalf of IRAS — expats pay it as consumers on everyday purchases and are not required to file it personally.

Property Tax

Property tax is an annual charge based on the Annual Value (AV) of a property. Expats who own and occupy a property in Singapore pay tax at owner-occupier rates, which from 1 January 2025 range from 0% to 16% of the annual value. For non-owner-occupied residential properties — such as those held as rental or investment assets — higher rates apply, ranging from 12% to 36% depending on the annual value.

Stamp Duty on Property Purchases

Property buyers in Singapore must pay Buyer’s Stamp Duty (BSD), calculated on the higher of the purchase price or market value. As of 15 February 2023, BSD rates for residential properties begin at 1% on the first S$180,000. Expats must also be aware of the Additional Buyer’s Stamp Duty (ABSD). As of 27 April 2023, Permanent Residents pay 5% on a first property and 30% on a second, while foreigners pay 60% on any residential property purchase. These figures are subject to revision — verify the latest rates on the IRAS website before committing to a transaction.

Capital Gains, Inheritance, and Wealth Taxes

Singapore levies no capital gains tax and no inheritance tax. Beyond the taxes described above, there are no additional taxes on income. For expats seeking to accumulate or protect wealth, this makes Singapore considerably more advantageous than many European or Latin American tax regimes.

Central Provident Fund (CPF)

The CPF is Singapore’s compulsory social security savings scheme, broadly comparable to a national pension system. Mandatory contributions apply almost exclusively to Singapore Citizens and Permanent Residents — the majority of foreign work pass holders are not required to participate. Should you become a Permanent Resident, CPF obligations will take effect, with contribution rates varying by age and employer type. Confirm your specific obligations with IRAS or the CPF Board directly.

Are there any tax breaks or special regimes for expats in Singapore?

Singapore does not operate a non-domicile regime or a remittance-based tax structure of the kind historically offered in the UK or through Portugal’s now-reformed NHR programme. Nevertheless, a number of meaningful advantages and reliefs are available to expats living and working in the country.

Territorial Tax — No Tax on Most Foreign Income

For many expats, the territorial tax principle itself represents the most valuable benefit. As a general rule, overseas income received in Singapore on or after 1 January 2004 is not subject to tax, including foreign income paid into a Singapore bank account. There is no requirement to declare such income. This stands in sharp contrast to countries that tax residents on all income regardless of its source.

Personal Tax Reliefs for Residents

Tax residents in Singapore may access a variety of reliefs and deductions that reduce their chargeable income. These include earned income relief, spouse relief, parent relief, and reliefs for course fees and charitable donations. From Year of Assessment 2018, the aggregate value of personal income tax reliefs an individual may claim is capped at S$80,000 per year.

Personal Income Tax Rebate

For Year of Assessment 2026 (covering income earned in 2025), Singapore will provide tax residents with a Personal Income Tax Rebate of 60% of tax payable, capped at S$200. This is applied automatically by IRAS when issuing assessments — no separate application is necessary. Comparable rebates have been offered in previous years, though the percentage and cap fluctuate from year to year; check the IRAS website for the current year’s details.

Supplementary Retirement Scheme (SRS)

The SRS is a voluntary savings vehicle open to Singapore Citizens, Permanent Residents, and foreigners alike. Contributions made to an SRS account can be offset against taxable income, directly lowering your annual tax liability. Withdrawals are taxable, but at a concessionary rate, making the SRS a tax-efficient mechanism for long-term savings during your time in Singapore. Refer to IRAS for the current contribution limits and withdrawal conditions.

Short-Term Employment Exemption

Non-residents who exercise employment in Singapore for 60 days or fewer in a calendar year are exempt from tax on that short-term employment income. This can be a useful relief for those on brief assignments, though it does not extend to directors of companies, public entertainers, or professionals.

Administrative Concessions for Longer Stays

To provide greater certainty for expatriates on multi-year postings, IRAS offers administrative concessions. If you have stayed and worked in Singapore continuously across two calendar years and your total period of presence or employment is at least 183 days, you will be treated as a tax resident for both years. Where you remain in Singapore continuously for three consecutive years, you are regarded as a tax resident throughout all three, even if you were physically present for fewer than 183 days in the first or third year. These concessions can have a meaningful impact on your tax position in the year you arrive or depart.

How and when do expats file a tax return in Singapore?

Singapore uses a calendar year as the basis for individual assessment: income earned between 1 January and 31 December is assessed in the Year of Assessment (YA) that follows. For instance, YA 2026 covers income earned from 1 January 2025 to 31 December 2025. This clean structure makes it straightforward to match income to the correct assessment period.

The step-by-step process for filing your Singapore income tax return is as follows:

1. Determine your tax residency status. Apply the 183-day rule and any relevant IRAS administrative concessions to establish whether you are a tax resident or non-resident for the applicable Year of Assessment. Your residency classification governs both your applicable rate and your access to personal reliefs.
2. Register with IRAS and obtain Singpass access. Expats can e-file via IRAS’s myTax Portal using a Singpass login for Singapore citizens and residents, or a Singpass Foreign Account for non-citizen expats. Set up your account at singpass.gov.sg well before the filing season begins.
3. Wait for your employer’s data to be submitted. Under the Auto-Inclusion Scheme, employers are required to submit employment income data (Form IR8A) to IRAS by 1 March each year. This information is automatically pre-filled into myTax, so most expat employees do not need to re-enter their salary details manually if their employer is enrolled in the scheme.
4. Begin e-filing from 1 March. The filing window opens on 1 March, once auto-included employer data has been loaded into returns. IRAS sends filing notifications by SMS, email, or letter between February and March. If you receive a notification, you may file your return from 1 March through to 18 April.
5. Declare all taxable income and claim eligible reliefs. Report all Singapore-sourced income, including salary, bonuses, rental income, and any taxable benefits-in-kind. Claim any personal reliefs and deductions you are entitled to, keeping in mind the S$80,000 annual cap.
6. Submit by the deadline. For income earned in 2024 (YA 2025), the paper filing deadline is 15 April 2025 and the e-filing deadline is 18 April 2025. Confirm current deadlines on the IRAS website each year, as they may be subject to adjustment.
7. Receive your Notice of Assessment (NOA). Following submission, IRAS issues a Notice of Assessment — your formal tax bill — at some point between late April and September. The NOA sets out your income, reliefs, and the amount of tax payable. Payment is generally due in November or December of the year of assessment.
8. Pay your tax bill. Settlement can be made via GIRO instalments or as a single lump-sum payment, in accordance with IRAS instructions. Scrutinise your NOA carefully; if you consider there to be an error, lodge a dispute through the “Object to Assessment” facility within 30 days of the NOA date.

Penalties may be imposed for late or inaccurate filing, ranging from composition amounts to formal enforcement action. If any step in the process is unclear, a tax adviser with experience in Singapore expat matters can help you navigate myTax Portal and reduce the risk of errors.

What are the tax implications of leaving Singapore?

Departing Singapore triggers a formal process known as tax clearance, which is particularly important for expats on employment passes. Your employer is legally obligated to notify IRAS and withhold any outstanding tax before releasing your final salary or other payments.

When you cease employment in Singapore, your employer is required to seek tax clearance — regardless of whether you were assessed as a resident or non-resident. This process is conducted through IRAS’s Form IR21, and your employer must submit the notification to IRAS at least one month before your final working day or departure from Singapore, whichever falls first. IRAS will then determine any remaining tax owed.

Once clearance is granted, IRAS issues a Clearance Directive informing your employer what amount may be released to you. It is strongly advisable not to depart Singapore before this process is underway — or at minimum before your employer has formally initiated it — to avoid complications with funds being withheld or delayed.

You are also required to file a final income tax return for the year of departure, covering all income earned up to the date you cease to be tax resident in Singapore. Generally, overseas income received in Singapore on or after 1 January 2004 is not taxable, and once you have left, income subsequently earned abroad and not derived from Singapore should not give rise to continuing Singapore tax obligations.

Equity-based compensation warrants close attention around the time of departure. Singapore taxes equity gains at the point of vesting or exercise, not at grant. For restricted stock units (RSUs), the taxable event is typically the vesting date. For options, it is ordinarily the exercise date, provided no selling restrictions remain; where restrictions do apply, taxation is deferred until they are lifted. Awards that remain unvested or unexercised at the point of departure may still attract Singapore tax when they vest or are exercised after you have left. Seeking professional advice well ahead of your departure date is strongly recommended.

Singapore does not currently impose a broad exit tax on unrealised gains in the manner of certain other countries. That said, the interplay between your departure and any outstanding obligations — particularly regarding equity compensation, property ownership, and CPF (for Permanent Residents) — makes early and careful planning essential. Engaging a tax adviser with cross-border expertise at least three to six months before you plan to leave is a prudent step.

Practical tips for managing taxes as an expat in Singapore

• Keep meticulous travel records from the moment you arrive. IRAS counts both arrival and departure days as days of presence in Singapore, and partial days are treated as full days for residency purposes. Anyone approaching the 183-day threshold should maintain a detailed log of all entry and exit dates throughout the year. A basic spreadsheet recording your travel movements is an easy and effective tool.
• Familiarise yourself with residency concessions before you arrive. If you are joining mid-year or on a multi-year posting, the two-year and three-year administrative concessions offered by IRAS may apply and could materially reduce your tax burden in the year of arrival. Clarify your position with a tax adviser or by reviewing the IRAS website before you file for the first time.
• Set up your Singpass account as early as possible. Filing via IRAS’s myTax Portal requires a Singpass account. Registering a Singpass Foreign Account can take some time, so do not leave this until filing season is already open.
• Scrutinise your employment package for taxable benefits. Expatriate compensation packages frequently include a variety of benefits-in-kind. Unless a specific exemption or IRAS concession applies, most such benefits are taxable. Housing allowances, home leave flights, school fees for dependants, and company car arrangements all carry specific tax treatment under IRAS rules — review each element carefully.
• Establish whether a DTA applies to your circumstances. If you continue to receive income from your home country — whether rental income, dividends, pension payments, or investment returns — a DTA may reduce or remove the tax chargeable in one jurisdiction. Obtain a Certificate of Residence from IRAS to support any claim for treaty relief in the other country.
• Begin planning your departure well in advance. The tax clearance process requires active employer involvement and cannot always be accelerated at short notice. The taxation of equity-based remuneration — particularly unvested RSUs or unexercised options — can be especially complex for employees who are internationally mobile. Take professional advice at least several months before your expected departure date.
• Consider using the SRS to lower your taxable income. Voluntary contributions to the Supplementary Retirement Scheme reduce your chargeable income and can provide a straightforward route to reducing your annual tax bill, especially if you are a higher earner.
• Engage a qualified tax adviser with cross-border experience. A specialist adviser will keep you informed of policy changes — such as new deductions or reliefs introduced in Singapore’s annual Budget — ensuring you do not overlook legitimate opportunities. While there is a cost involved, the potential tax savings and the avoidance of errors or penalties will often make this a worthwhile investment, particularly for those with complex arrangements or high incomes.

Frequently asked questions: taxation in Singapore for expats

Am I taxed on my worldwide income in Singapore?

Singapore applies a territorial tax principle, which means that liability to tax is confined to income originating within Singapore. Income from foreign sources is generally outside the scope of Singapore tax, unless it is received in Singapore through a local partnership. For most expats, income earned and retained overseas will not attract Singapore tax.

When do I become a tax resident in Singapore?

The foundational test is the 183-day rule: if you are physically present in Singapore for 183 days or more in a calendar year, you are generally treated as a tax resident and assessed at progressive rates with entitlement to personal reliefs. Administrative concessions also allow tax residency to be conferred on individuals whose continuous employment spans two calendar years with a combined presence of at least 183 days.

What is the deadline for filing my Singapore tax return?

Depending on your circumstances, IRAS may place you on an auto-inclusion or no-filing arrangement. Where IRAS does issue a filing notification, the standard deadlines are 15 April for paper returns and 18 April for e-filing. Deadlines can occasionally vary, so verify the current position on the IRAS website each year.

Is there capital gains tax in Singapore?

No. Singapore does not levy capital gains tax or inheritance tax, making it an attractive base for expats looking to grow or preserve wealth. Proceeds from selling shares, property, or other assets are generally free of tax, though professional advice is recommended for transactions of significant value or complexity.

Do I need to pay tax on foreign pension income received in Singapore?

As a general rule, overseas income received in Singapore on or after 1 January 2004 is not taxable, including amounts paid into a Singapore bank account. Foreign pension receipts in Singapore typically fall within this exemption, but the precise treatment depends on how the pension is categorised and whether payments are routed through a Singapore partnership. Verify your specific situation with IRAS or a tax adviser.

What happens to my tax obligations when I leave Singapore?

Your employer must initiate tax clearance by submitting Form IR21 to IRAS at least one month before your employment ends or you depart Singapore, whichever comes first. IRAS will assess your outstanding tax liability and issue a Clearance Directive to your employer. You should also file a final tax return and settle any open assessments before leaving. Note that unvested equity awards may continue to generate Singapore tax obligations even after your departure.

Does Singapore have a double taxation agreement with my home country?

Singapore has concluded Avoidance of Double Taxation Agreements with approximately 100 jurisdictions. The complete and up-to-date list can be found on the IRAS DTA database. Agreements that are signed but not yet ratified do not have legal effect. If your home country has no DTA with Singapore, a Unilateral Tax Credit may still be available in respect of foreign taxes paid.

Are benefits-in-kind from my employer taxable in Singapore?

Unless a specific exemption applies or IRAS has granted an administrative concession, most benefits-in-kind provided as part of an expatriate package are taxable. Common examples include housing allowances — which are taxed on the basis of actual rent paid or the annual value of the property — home leave flights, school fees for dependent children, and company car benefits. Review each element of your remuneration package with a tax adviser to determine the taxable amount attributable to each benefit.
