Tax

Navigating Singapore’s tax landscape

By: Adrian Sham, Eng Min Lor, Alex Yam

Singapore’s tax system covers a range of considerations for businesses operating, investing or transacting in the country. This guide provides an overview of key areas of Singapore taxation, including the tax framework, corporate income tax and other considerations relevant to businesses.

This Q&A was first published in the Singapore chapter of Legal 500’s Tax Comparative Guide here.

Singapore tax legislation is generally amended on an annual basis to implement tax measures announced in the annual budget, which is typically tabled in February each year. Such changes are commonly effected through amendments to the Income Tax Act 1947, Goods and Services Tax Act 1993, Stamp Duties Act 1929 and other relevant tax legislation. Tax laws may also be amended at other times during the year, where necessary, to respond to evolving economic conditions, policy objectives or international tax developments.

The legislative process typically begins with the announcement of proposed tax measures in the budget. Depending on the nature of the changes, draft legislation may be released for public consultation before the relevant amendment Bills are introduced and debated in Parliament. Once passed by Parliament and assented to by the President, the legislative amendments become law. In addition to statutory changes, the Inland Revenue Authority of Singapore (“IRAS”) regularly issues e-Tax Guides, circulars and other administrative guidance to clarify the interpretation and practical application of Singapore’s tax laws.

Companies carrying on business in Singapore are generally required to:

  • file an Estimated Chargeable Income within three months after the end of their financial year, unless an administrative exemption applies;
  • file an annual corporate income tax return (Form C-S, Form C-S (Lite) or Form C, as applicable) by 30 November of the year following the end of their financial year;
  • maintain proper accounting records and supporting documentation;
  • retain records for at least five years from the relevant Year of Assessment; and
  • comply with GST registration, filing and payment obligations where required.

Individuals are required to file annual income tax returns by 18 April, unless they qualify for the No-Filing Service regime.

Additional compliance obligations may arise under transfer pricing, country-by-country reporting, automatic exchange of information and Pillar Two legislation.

The principal tax authority is the IRAS, which administers income tax, goods and services tax (“GST”), stamp duty and certain other taxes.

IRAS may perform a desktop review of the tax computation lodged. IRAS generally adopts a cooperative and transparent approach to tax administration. Taxpayers may seek clarification through advance rulings, engage with IRAS during the audits and reviews, and discuss disputed matters through correspondence and meetings. In practice, many issues are resolved through administrative engagement before progressing to formal objection and appeal procedures.

The Ministry of Finance is responsible for tax policy, while IRAS is responsible for its administration and enforcement.

A taxpayer who disagrees with any assessment raised by the IRAS must lodge a valid objection with the IRAS on timely basis (within 2 months from the date of the Notice of Assessment for a company and 30 days for an individual respectively). If the dispute remains unresolved, the taxpayer may ask for a notice of refusal to amend and refer the issue to the Income Tax Board of Review (“ITBR”), an independent tribunal.

Further appeals may be made to the General Division of the High Court, with further rights of appeal governed by the Supreme Court of Judicature Act and Rules of Court.

The duration of proceedings depends on the complexity of the case. Administrative review may take several months, while proceedings before the ITBR and the courts can take one to several years.

Corporate income tax and individual tax assessment are payable within one month from the date of the Notice of Assessment unless instalment arrangements are approved by IRAS.

GST registered businesses generally file GST returns quarterly and pay any GST due within one month after the end of the accounting period.

Notwithstanding any objection, the tax assessed is payable by the due date, unless IRAS exercises its discretion to defer the collection.

Yes.

Taxpayer information is protected by statutory confidentiality provisions under Singapore tax law. Officers of the IRAS are subject to strict confidentiality obligations, and unauthorised disclosure of taxpayer information may constitute an offence.

These protections are, however, subject to statutory exceptions. Information may be disclosed where authorised by law, including for law enforcement and regulatory purposes, the exchange of information under Singapore’s tax treaties, the Common Reporting Standard (“CRS”), and other international tax cooperation and information-sharing arrangements.

Singapore has implemented the OECD CRS and participates in the automatic exchange of financial account information with partner jurisdictions pursuant to its international tax information exchange commitments.

Singapore’s beneficial ownership regime requires most companies, foreign companies registered in Singapore and LLPs to identify their beneficial owners and maintain a private register of registrable controllers. Prescribed beneficial ownership information must also be filed with the Central Register of Registrable Controllers maintained by the Accounting and Corporate Regulatory Authority (“ACRA”). Neither the private register nor the Central Register is generally available for public inspection, although the information may be accessed by ACRA and other competent authorities for regulatory, supervisory, investigative and law enforcement purposes in accordance with applicable law.

A company is generally regarded as tax resident in Singapore if its control and management are exercised in Singapore. The test focuses on where strategic decisions concerning the company’s business are made, typically where board meetings are held and key management decisions are taken.

Partnerships are generally treated as tax transparent for Singapore income tax purposes, with each partner subject to tax on its share of the partnership income. As the partnership itself is generally not a taxable person, tax residency is ordinarily considered at the partner level rather than at the partnership level.

In practice, the IRAS may issue a certificate of taxable status confirming that the partnership has filed a Singapore partnership tax return. Such a certificate does not constitute a certificate of tax residence and should be distinguished from a certificate of residence issued to a Singapore tax resident taxpayer.

Yes. IRAS actively reviews cross border related party arrangements as part of its transfer pricing compliance and audit programme.

Companies filing Form C are required to disclose whether their total related party transactions exceed SGD 15 million and, where the threshold is exceeded, to complete the Form for Reporting of Related Party Transactions (“RPT Form”). IRAS uses the information disclosed in the RPT Form for transfer pricing risk assessment. Taxpayers may also be required to submit contemporaneous transfer pricing documentation and other information to IRAS as part of a transfer pricing review or audit.

IRAS’ review focuses on whether related party transactions are conducted on arm’s length terms. Areas of particular relevance include transactions involving goods and services, intercompany financing, intellectual property and business restructurings.

Where IRAS determines that the conditions of a related party transaction are not arm’s length, it may make a transfer pricing adjustment under section 34D of the Income Tax Act. A 5% surcharge is generally imposed on the amount of the transfer pricing adjustment, regardless of whether the adjustment results in additional tax payable. The Comptroller may, however, remit the surcharge wholly or in part for good cause, including where the taxpayer has been cooperative during the transfer pricing audit or review and has maintained a good compliance record.

No.

Singapore does not currently have a CFC regime. Accordingly, foreign subsidiaries are generally not subject to a deemed income inclusion or attribution regime merely because they are controlled by Singapore-resident shareholders.

However, Singapore’s tax system includes other measures that may limit the tax benefits of holding income offshore, including anti-avoidance provisions applicable to foreign-sourced income exemption claims. In addition, multinational enterprise groups within the scope of the OECD Pillar Two / Global Anti-Base Erosion (“GloBE”) Rules may be subject to top-up taxes under Singapore’s Pillar Two legislation where the effective tax rate in a jurisdiction falls below the prescribed minimum rate.

Accordingly, whilst Singapore does not operate a CFC regime, certain overseas profits may nevertheless be affected by Singapore’s anti-avoidance rules and Pillar Two framework.

Transfer pricing

Singapore has a comprehensive transfer pricing regime based on the arm’s length principle. Taxpayers are required to conduct related party transactions on arm’s length terms and, where prescribed conditions and thresholds are met, to prepare and maintain contemporaneous transfer pricing documentation.

Thin capitalisation

Singapore does not have formal thin capitalisation rules that prescribe a maximum debt-to-equity ratio. However, related party financing arrangements are subject to the arm’s length principle, including the appropriate delineation and pricing of the financing arrangement. The deductibility of interest is separately subject to the general provisions of the Income Tax Act. In addition, where borrowings are used to acquire assets that do not generate taxable income, a corresponding restriction on interest deductibility may arise. As a result, Singapore’s interest deductibility rules may, in certain circumstances, operate as a practical constraint on excessive leverage.

Safe harbours and simplified approaches

Singapore does not have a single general statutory transfer pricing safe harbour. IRAS nevertheless provides a number of targeted administrative practices and simplified approaches. These include a 5% cost mark-up for specified routine support services where the relevant conditions are satisfied, and an indicative margin that taxpayers may elect to apply to qualifying related party loans.

For related party domestic loans entered into on or after 1 January 2025 where neither party is in the business of borrowing and lending money, IRAS will not make a transfer pricing adjustment under section 34D in respect of the loan and will not request transfer pricing documentation in relation to it. This treatment does not affect the application of the ordinary rules governing the deductibility or restriction of interest expense.

In addition, IRAS is implementing the OECD simplified and streamlined approach for qualifying baseline marketing and distribution transactions on an optional pilot basis for financial years beginning from 1 January 2026 to 31 December 2028.

Advance pricing agreements

Unilateral, bilateral and multilateral advance pricing arrangements (“APAs”) are available in Singapore. A unilateral APA is agreed between IRAS and the taxpayer, while bilateral and multilateral APAs involve IRAS and one or more relevant foreign competent authorities, generally under Singapore’s applicable double tax agreements.

Yes. Singapore’s GAAR is contained in section 33 of the Income Tax Act. The provision empowers the Comptroller of Income Tax to disregard, vary or make such adjustments as are appropriate in respect of an arrangement where it is determined that the purpose or effect of the arrangement is the avoidance or reduction of Singapore tax.

The IRAS may invoke the GAAR during tax audits, reviews and assessments. In practice, the application of section 33 is guided by judicial principles developed by the Singapore courts, including consideration of whether the arrangement has commercial substance and whether it results in a tax advantage that is inconsistent with the intent of the relevant tax provisions.

Taxpayers may challenge the application of section 33 through the statutory objection and appeal process. Disputes may ultimately be determined by the Singapore courts.

Singapore does not impose a separate digital services tax.

However, GST applies to imported digital services and low-value imported goods supplied to consumers in Singapore under the Overseas Vendor Registration regime.

Singapore remains committed to a multilateral solution through the OECD framework and has not announced plans for a standalone digital services tax.

Singapore has implemented the principal elements of the OECD BEPS 2.0 Pillar Two framework, other than the Undertaxed Profits Rule, for financial years commencing on or after 1 January 2025 through the introduction of:

  • a Domestic Top-up Tax; and
  • a Multinational Enterprise Top-up Tax.

These measures generally apply to multinational enterprise groups with annual revenue of at least €750 million in the consolidated financial statement of the ultimate parent entity in at least two of the four financial years preceding the tested financial year. Broadly, the rules are intended to ensure a minimum effective tax rate of 15% on a jurisdictional basis.

Singapore has not implemented Pillar One Amount A. However, Singapore has adopted the OECD’s simplified and streamlined approach (SSA) for qualifying baseline marketing and distribution activities, which corresponds to as Amount B under the OECD/G20 BEPS 2.0 framework. The SSA is available on an optional pilot basis for financial years beginning from 1 January 2026 to 31 December 2028. Where the prescribed qualifying conditions are satisfied and the taxpayer elects to apply the approach, IRAS will treat the resulting outcome as being consistent with the arm’s length principle.

The OECD BEPS project has had a significant impact on Singapore’s international tax framework.

Examples include:

  • transfer pricing legislation and documentation requirements;
  • country-by-country reporting obligations;
  • exchange of information initiatives;
  • economic substance requirements within tax incentive regimes;
  • adoption of the Multilateral Instrument; and
  • implementation of Pillar Two minimum tax rules.

Singapore’s approach has generally been to align with international standards while maintaining its competitiveness as a business hub.

Yes. Singapore’s tax system broadly follows the OECD model in that it taxes business profits, employment income and various forms of investment income.

However, Singapore operates a modified territorial/source-based system and does not generally impose tax on capital gains. GST applies as the principal indirect tax.

a) Business profits

Business profits derived from or accruing in or received or deemed received in Singapore, are subject to corporate income tax.

  • Corporate income tax is levied at a flat rate of 17% on a company’s chargeable income.
  • Various tax exemption and incentive schemes may reduce the effective rate for qualifying companies.

b) Employment income and pensions

Employment income is taxable in Singapore

  • Tax resident individuals are taxed at progressive rates ranging from 0% to 24%.
  • Taxable employment income generally includes salaries, bonuses, benefits-in-kind and share-based remuneration.
  • Non-resident employees are generally taxed at the higher of:
    • a flat rate of 15% on employment income; or
    • the progressive resident rates.

Singapore does not have a comprehensive pension tax regime comparable to many OECD countries. Withdrawals from Singapore’s compulsory retirement savings scheme, the Central Provident Fund (CPF), are not subject to tax. Contributions made by employers to CPF in accordance with the CPF Act are not taxable to employees. Only 50% of withdrawals from the voluntary Supplemental Retirement Scheme taken at the statutory retirement age is taxable, whilst early withdrawals generally incur a 5% penalty and are 100% taxable.

c) VAT (or other indirect tax)

Singapore levies GST, which is a value-added tax.

  • The standard GST rate is 9%.
  • GST generally applies to supplies of goods and services made in Singapore and to imports of goods.
  • Certain supplies are zero-rated (e.g. exports of goods and specified international services) while others are exempt (e.g. many financial services and residential property transactions).

d) Savings income and royalties

Interest (savings income)

  • Interest received by companies forms part of taxable income unless a specific exemption applies.
  • For individuals, bank deposit interest from approved Singapore banks and licensed financial institutions is generally exempt from tax.

Royalties

  • Royalties derived by a Singapore tax resident company are generally taxed as ordinary income at 17%.
  • Royalties paid to non-residents may be subject to withholding tax, generally at 10% for the use of movable property or intellectual property, subject to applicable treaty relief and domestic law provisions.

e) Income from land

Income from land is generally taxable where it is revenue in nature.

  • Rental income derived from Singapore real property is subject to income tax.
  • For individuals, the income is taxed at the applicable personal income tax rates (up to 24% for residents).
  • For companies, rental income is generally taxed at the corporate income tax rate of 17%.

f) Capital gains

Singapore does not impose capital gains tax.

Gains derived from the disposal of shares, investments or other assets are generally not taxable where they are capital in nature. However, such gains may be subject to income tax if they are regarded as revenue in nature, including where the taxpayer is carrying on a trade or business involving the acquisition and disposal of the relevant assets.

Notwithstanding the above, section 10L of the Singapore Income Tax Act, which applies to disposals occurring on or after 1 January 2024, may subject certain gains from the sale or disposal of foreign assets to Singapore income tax. Broadly, the provision applies to gains that are received (or deemed received) in Singapore by an entity that is a member of a relevant group. The taxation of such gains depends on the specific circumstances, including whether the relevant exclusions or economic substance requirements are satisfied.

g) Stamp and/or capital duties

Singapore imposes stamp duty but does not impose any general capital duty.

Stamp duty may apply to:

  • transfers of Singapore immovable property;
  • leases of immovable property; and
  • transfers of shares in Singapore-incorporated companies.

For share transfers:

  • stamp duty is generally 0.2% of the higher of the consideration paid or the net asset value of the shares transferred.

For real estate transactions:

  • Buyer’s Stamp Duty (BSD) is payable at progressive rates (up to 6%) depending on the type and value of the property.
  • Additional Buyer’s Stamp Duty (ABSD) of up to 65% is an additional property tax applied when buying residential property in Singapore. It is levied from the second property for Singapore Citizens, and generally from the first property for all other buyers.
  • Seller’s Stamp Duty (SSD) of up to 16% is an additional property tax on selling residential or industrial property within a minimum holding period.

Capital duty

  • Singapore does not currently impose any capital duty on the issuance of share capital.

Broadly, yes. Singapore business income is generally computed by reference to the accounting profits of the business. However, taxable income is determined in accordance with the provisions of the Singapore Income Tax Act rather than accounting principles alone.

Accordingly, where the accounting treatment differs from the applicable tax treatment, adjustments are required to compute taxable profits. Common adjustments include the disallowance of non-tax deductible expenses, differences in the timing of income recognition and deductions, and the replacement of accounting depreciation with tax depreciation (capital allowances).

As a result, whilst accounting profits generally form the starting point for determining taxable income, the final tax liability is calculated based on Singapore tax principles.

Companies are taxable entities.

Unlike companies, partnerships (including general partnerships, LLPs and LPs) are generally treated as tax transparent for Singapore income tax purposes, with tax imposed at the partner level rather than at the partnership level.

For trusts, the Singapore tax treatment depends on the structure of the trust arrangement. Depending on the nature of the income, the activities of the trust, the status of the beneficiaries and the terms of the trust deed, a trust may be treated as tax transparent, with the income taxed in the hands of the beneficiaries. Alternatively, the trustee may be assessed to tax on the trust income on behalf of the beneficiaries.

Singapore does not impose business taxation solely by reference to tax residence or registration.

The key consideration is whether the income-generating activities are conducted in Singapore. Under Singapore’s modified territorial basis of taxation, income derived from or accrued in Singapore is generally subject to tax, together with certain categories of foreign-sourced income received in Singapore.

Singapore does not operate enterprise zone or free-zone tax regimes that provide tax benefits solely based on location. Rather, its tax incentive framework is focused on encouraging specific industries and activities, including financial services, fund management, treasury centres, international trading, maritime activities, and research and development.

Depending on the applicable incentive and the satisfaction of relevant conditions, qualifying entities may benefit from concessionary corporate income tax rates, tax exemptions, or enhanced tax deductions and allowances.

Singapore does not have a traditional patent box regime. However, companies that develop and commercialise qualifying intellectual property arising from R&D activities in Singapore may apply for the Intellectual Property Development Incentive (“IDI”).

Subject to approval and the satisfaction of prescribed conditions, qualifying intellectual property income may be taxed at concessionary rates of 5%, 10% or 15% under a regime that is aligned with the OECD’s modified nexus approach.

Singapore does not have a fiscal consolidation regime and group companies are generally taxed separately.

However, Singapore operates a group relief regime that allows a qualifying company to transfer certain current-year tax losses, capital allowances and donations to another qualifying company within the same group, subject to prescribed ownership and other conditions. Generally, the companies must be incorporated in Singapore and be members of the same group satisfying at least a 75% shareholding test.

Loss transfers are limited to qualifying current-year items. Singapore does not permit the transfer of unutilised losses or capital allowances brought forward from prior years between group companies.

Yes. Withholding tax may apply to interest, royalties and certain payments made to non-residents.  Relief or reduction of withholding tax may be available under the applicable double tax treaty.

Singapore imposes a carbon tax on large emitters and offers various incentives to encourage sustainable business practices and emissions reduction. Available support measures include grants for energy efficiency enhancements, resource and emissions efficiency projects, and sustainability capability-building initiatives, including the Energy Efficiency Grant, the Resource Efficiency Grant for Emissions and the Enterprise Sustainability Programme.

Singapore sourced dividends are generally exempt from tax under the one-tier corporate tax system. There is no Singapore withholding tax on dividend payment.

Foreign sourced dividends received in Singapore may qualify for exemption under the foreign sourced income exemption rule if certain conditions are met. In addition, where taxable, foreign tax credit may be claimed on such dividends.

Singapore offers a number of advantages for international groups seeking to relocate activities to the jurisdiction. These include a competitive corporate income tax rate of 17%, the absence of general capital gains tax, an extensive network of double taxation agreements, a stable political and regulatory environment, and a range of tax incentives for qualifying activities, including regional headquarters functions, R&D activities and intellectual property development. Singapore also operates a territorial tax system under which certain foreign-sourced income may be exempt from tax.

Potential disadvantages include relatively high labour and operating costs compared to certain neighbouring jurisdictions, increasing economic substance requirements in relation to tax incentives, and the implementation of the OECD Pillar Two global minimum tax rules for in-scope multinational enterprise groups.
