What accounting standards are used in Singapore?

Singapore companies generally prepare their financial statements in accordance with the Singapore Financial Reporting Standards (SFRS), which are closely aligned with International Financial Reporting Standards (IFRS).

The accounting standards a company uses depend on its size, structure, and reporting requirements.

Most local companies use SFRS, while some entities with international reporting obligations may apply SFRS(I).

Businesses must maintain proper accounting records that accurately reflect their transactions and financial position.

These records typically include:

    • Invoices and receipts
    • Bank statements
    • Payroll records
    • Contracts and agreements
    • Asset registers
    • Financial statements

Under Singapore law, accounting records generally must be retained for at least five years.

Do all companies in Singapore need to be audited?

No. Many companies in Singapore qualify for audit exemption.

A company may be exempt from audit requirements if it qualifies as a small company under Singapore's Companies Act.

Generally, a company may qualify if it satisfies at least two of the following criteria for the relevant financial years:

    • Annual revenue does not exceed S$10 million
    • Total assets do not exceed S$10 million
    • Number of employees does not exceed 50

Companies that do not qualify for audit exemption must appoint an auditor and submit audited financial statements where required.

Even when an audit is not mandatory, maintaining accurate financial records remains a legal requirement.

Do businesses pay tax in Singapore?

Yes. Both local and foreign-owned businesses operating in Singapore may be subject to Singapore taxation.

Singapore does not distinguish corporate tax rates based on the nationality of shareholders.

Instead, taxation depends on factors such as:

    • Whether the company is tax resident in Singapore
    • The source of income
    • Whether foreign-sourced income qualifies for exemptions
    • The nature of business activities conducted in Singapore

Local companies and foreign-owned subsidiaries generally pay tax under the same corporate tax framework.

Foreign companies operating through a branch or permanent establishment in Singapore may also be subject to Singapore taxation on qualifying income.

How does corporate tax work in Singapore?

Singapore applies a territorial-based taxation system with a headline corporate income tax rate of 17%.

Under this system, tax is generally imposed on:

    • Income earned in Singapore
    • Income accrued in Singapore
    • Certain foreign-sourced income received in Singapore

One of the key features of Singapore's tax regime is that foreign-sourced income may qualify for exemptions if specific conditions are satisfied.

The effective tax rate paid by many businesses is often lower than the headline 17% rate due to available exemptions and incentives.

Singapore also generally does not impose:

    • Capital gains tax
    • Dividend withholding tax on distributions to shareholders
    • Estate or inheritance taxes

These characteristics contribute to Singapore's reputation as an attractive jurisdiction for regional and international business operations.

What is the withholding tax rate in Singapore?

Singapore's withholding tax rate typically ranges from 10% to 24%, based on the type of payment made to a non-resident and whether a double taxation agreement (DTA) applies.

Common withholding tax rates include:

    • Royalties: 10% of the gross payment
    • Interest: 15% of the gross payment
    • Professional and management fees: Generally 15% to 17%, depending on the circumstances
    • Director's remuneration: 24%
    • Rent or other payments for the use of movable property: 15% (gross payment)

Singapore has an extensive network of double taxation agreements (DTAs), which may reduce withholding tax rates for qualifying foreign recipients.

Because withholding tax obligations can vary significantly depending on the transaction structure and treaty provisions, businesses should review cross-border payments carefully before making distributions.

Who needs to register for GST in Singapore? 

A Singapore company must register for GST if its taxable turnover exceeds S$1 million, or is expected to exceed S$1 million under Inland Revenue Authority of Singapore (IRAS) registration rules.

Businesses below the threshold may choose voluntary registration if it supports their commercial objectives.

Once GST-registered, a business must:

    • Charge GST on taxable supplies where applicable
    • File GST returns
    • Maintain GST records
    • Comply with GST reporting requirements

Whether voluntary GST registration is beneficial depends on factors such as customer profile, industry, input tax recovery opportunities, and anticipated business growth.

What is annual return filing in Singapore?

Annual return filing is a legal requirement for all Singapore companies. It involves submitting key company information to the Accounting and Corporate Regulatory Authority (ACRA) each year to keep the company's records up to date.

Information commonly included may cover:

    • Company officers
    • Registered office details
    • Shareholding information
    • Financial reporting status

Failure to file annual returns on time can result in penalties and regulatory consequences.

Annual return filing is separate from tax filing obligations with the Inland Revenue Authority of Singapore (IRAS).

When to file a corporate tax return in Singapore?

Singapore companies generally must file their Corporate Income Tax Return by 30 November, while Estimated Chargeable Income (ECI) is typically due within three months of the financial year-end, unless an exemption applies.

Singapore companies generally have two key corporate tax filing obligations:

Estimated Chargeable Income (ECI)

Estimated Chargeable Income (ECI) is a company's estimate of its taxable income for the relevant Year of Assessment and is used by IRAS to assess corporate tax liabilities.

Corporate Income Tax Return

The Corporate Income Tax Return reports a company's actual taxable income, deductions, exemptions, and tax liabilities for the relevant Year of Assessment.

Timely filing is important because late submissions may result in penalties, enforcement actions, or estimated assessments issued by the tax authority.

Are there any tax incentives for companies in Singapore?

Yes. Singapore offers numerous tax incentives, such as SUTE and PTE, designed to attract investment, innovation, and international business activity.

Some commonly used incentives include:

Start-Up Tax Exemption (SUTE)

Eligible newly incorporated companies may benefit from the Start-Up Tax Exemption scheme during their first three Years of Assessment.

The scheme provides substantial tax exemptions on a portion of chargeable income, helping reduce the tax burden for qualifying startups during their early growth phase.

Partial Tax Exemption (PTE)

Companies that do not qualify for SUTE may still benefit from Singapore's Partial Tax Exemption scheme.

Under this framework, a portion of a company's chargeable income receives tax exemption, reducing the effective corporate tax rate for many small and medium-sized businesses.

Industry-Specific Incentives

Singapore offers targeted tax incentives to attract investment in strategic sectors. Examples include:

    • Financial services incentives for qualifying banking, fund management, and insurance activities
    • Pioneer and Development and Expansion Incentives for companies undertaking substantial manufacturing or business expansion projects
    • Technology and innovation incentives designed to support high-value activities and digital transformation
    • Logistics and supply chain incentives for businesses establishing regional operations in Singapore

Eligibility requirements vary depending on the industry and investment commitments involved.

Research and Innovation Support

Businesses investing in innovation may qualify for various support programs and tax benefits.

Common examples include:

    • Enhanced deductions for qualifying research and development (R&D) activities
    • Incentives supporting intellectual property development and commercialization
    • Government grants for technology adoption and innovation projects
    • Funding schemes that encourage productivity improvements and business transformation

The availability and eligibility criteria for tax incentives can change over time, making periodic review important.

When should a business hire an accountant or tax advisor in Singapore?

Many businesses benefit from professional accounting and tax support long before compliance issues arise.

Common situations where professional advice may be valuable include:

Company Formation

An accountant can help establish accounting systems and reporting processes from the beginning.

Rapid Growth

As revenue and transaction volumes increase, compliance requirements often become more complex.

GST Registration

Businesses approaching GST thresholds may require guidance on registration obligations and GST planning.

International Expansion

Cross-border operations frequently involve withholding tax, transfer pricing, tax residency, and foreign income considerations.

Tax Planning

Professional advisors can help identify legitimate tax efficiencies and ensure compliance with changing regulations.

Audit Preparation

Businesses approaching audit thresholds often benefit from early preparation and review of financial controls.

For many growing companies, proactive advice is generally less costly than correcting compliance issues after they arise.

Conclusion

Singapore's appeal is not solely its 17% corporate tax rate or tax incentives.

For many businesses, the greater advantage is the combination of predictable tax rules, relatively straightforward compliance requirements, and broad access to international markets through its treaty network and business-friendly regulatory environment.

As a result, accounting and tax planning in Singapore often becomes a strategic consideration for business expansion, regional headquarters planning, and cross-border operations rather than simply a compliance exercise.

FAQs

Is Singapore heavily taxed?

No. Singapore is generally considered a low-tax jurisdiction compared with many developed economies.

The corporate tax rate is 17%, and various exemptions and incentives may reduce the effective tax burden for eligible businesses.

What are the advantages of Singapore's tax system?

Singapore's tax system offers competitive corporate tax rates, no capital gains tax, extensive tax treaty coverage, startup tax incentives, and exemptions for certain foreign-sourced income.

Additional advantages include a transparent tax administration system and a stable regulatory environment, which help businesses plan and manage their tax obligations with greater certainty.

Is ACRA only for Singapore companies?

No. ACRA regulates not only Singapore companies but also other business entities registered in Singapore, including sole proprietorships, partnerships, limited partnerships, and limited liability partnerships.

ACRA oversees business registration, annual filings, financial reporting requirements, and corporate compliance for entities operating under Singapore's regulatory framework.

Do businesses in Singapore get tax back from business expenses?

Businesses in Singapore generally do not receive a direct tax refund for ordinary business expenses.

Instead, qualifying business expenses can be deducted from taxable income, which may reduce the amount of corporate tax payable.

What is the difference between dormant ACRA and IRAS?

Dormant ACRA status relates to a company's accounting and corporate compliance activities, while dormant IRAS status relates to whether the company is considered inactive for tax purposes.

A company may qualify as dormant under one authority but not the other because ACRA and IRAS apply different criteria.
