Singapore Company Formation, Tax Services and Annual Compliance

As Singapore has adopted the territorial concept of taxation, income tax is imposed on Singapore-source income at 17 per cent and, with certain exceptions, on foreign-source income received in Singapore.  If a newly-incorporated Singapore company has fewer than 20 shareholders and at least one shareholder is an individual beneficially holding at least 10 per cent of the company’s issued ordinary shares, the company can claim for full tax exemption on the first SGD100,000 of normal chargeable income in each of its first three consecutive financial years.  A further 50 per cent exemption is given to the next SGD200,000 of normal chargeable income for these three years, which may reduce the corporate income tax rate to 5.67 per cent for the first SGD300,000 of taxable income. 

Foreign-source dividends received in Singapore are exempt from tax subject to the following conditions: 

• The foreign income must be received from a jurisdiction with a headline
  tax rate of at least 15 per cent. 
• The income must have been subject to tax in the jurisdiction from which it is received. 

If either of these conditions is not fulfilled, it may be possible for the Singapore company to obtain a foreign tax credit. 

Under the one-tier corporate tax system, corporate tax paid is a final tax. Thus, dividends paid by a Singapore company are not subject to any withholding tax in the hands of its shareholders. 

There is no tax on capital gains in Singapore. In effect, gains arising from the disposal of investments or assets of a Singapore company are not subject to any tax. In addition, there are no controlled foreign company or thin capitalisation rules in Singapore (we cover details about USA tax Singapore).  Singapore companies can apply for headquarters incentives. The purpose of these incentives is to encourage multinational companies to locate either their regional or international headquarters in Singapore. 

Other incentives, such as Pioneer status and the Development and Expansion Incentive, are also available.

Singapore has more than 65 double- taxation agreements, whose benefits include the availability of a reduced withholding tax rate or exemption from withholding tax on certain classes of income, such as dividends, interest and royalties.  In addition, a Singapore company can reduce or eliminate withholding tax on the repatriation of profits. 

Singapore has adopted the mutual agreement procedure in its tax treaties; this offers a dispute-resolution channel in the event of transfer pricing adjustments.  Thus, it allows both the Inland Revenue Authority of Singapore and the respective foreign tax authorities to consult with a view to resolving a conflicting situation for taxpayers. 

Singapore has concluded free-trade agreements (FTAs) with the Association of Southeast Asian Nations jurisdictions, among others.  An FTA is a legally binding agreement between two or more countries to reduce or eliminate barriers to trade in, or facilitate the cross-border movement
of goods and services between, the territories of the parties.  With FTAs, Singapore-based exporters and investors stand to enjoy myriad benefits, such as tari concessions, preferential access to certain sectors, faster entry into markets and intellectual property protection. 

Succession planning and asset protection are usually key objectives for business owners.  The establishment of an onshore trust or foundation on top of a Singapore company should be considered with a view to facilitating the transfer of business participations to the next generation, or simply to organise the succession in favor of specific family members or partners.  This may avoid the costly process of probate; provide protection from creditors, in-laws and divorces; and o er protection and tax savings for beneficiaries in the long term.

Unlike some countries, Singapore’s corporate tax filing is a two-part process involving both an Estimated Chargeable Income (ECI) declaration and the final Form C-S/ C.

Part 1: Estimated Chargeable Income (ECI)

The ECI is an advance declaration of your company’s taxable income for the Year of Assessment (YA).

• What it is: An estimate of your company’s chargeable income (i.e., taxable profit after all deductions) for the financial year that just ended.

• Who must file: All companies are required to file an ECI within three months of their financial year-end, unless they qualify for an automatic waiver.

• Automatic ECI Waiver: A company is not required to file an ECI if it meets ALL of the following conditions for that financial year:

  1. Annual revenue is not more than $5 million.

  2. ECI is NIL.

  3. The company is not claiming the Cash Payout under the Corporate Income Tax Rebate (or has chosen to opt out).

• Deadline: Within 3 months after the end of the company’s financial year.

• Purpose: Allows the Inland Revenue Authority of Singapore (IRAS) to issue an advance tax bill (the “Notice of Assessment”) so companies can pay their taxes in installments, easing cash flow.

Part 2: Annual Income Tax Return (Form C-S or Form C)

This is the final and formal tax return for the year.

• Filing Basis: Income earned in the preceding financial year. For example, if your company’s financial year ended on 31 Dec 2023, you will file the tax return in 2024 for the Year of Assessment (YA) 2024.

• Filing Deadline: 30 November of each year (e.g., 30 Nov 2024 for YA2024). This is a strict deadline.

There are Two Main Types of Tax Return Forms:

1. Form C-S (Simplified)

• Eligibility: Companies with revenue of S$5 million or below that meet these criteria:

  • Derive income only from Singapore.

  • Do not claim any of the following:

    • • Carry-back of current year capital allowances/ losses

      • Investment Allowance

      • Group Relief

      • Foreign Tax Credit

      • Withholding Tax exemptions

• Features:

  • A simplified two-page form.

  • Pre-filled with information based on your ECI and previous filings.

  • Requires minimal additional information—mainly a confirmation of the pre-filled data.

2. Form C

• Eligibility:

  • Companies with revenue exceeding S$5 million.

  • Companies that do NOT qualify for Form C-S (e.g., they are claiming group relief or foreign tax credits).

• Features:

  • A more detailed form.

  • Requires a full set of financial statements (Profit & Loss, Balance Sheet, and supporting schedules).

  • Requires a detailed tax computation reconciling accounting profit to taxable income.

Step-by-Step Filing Timeline (Example for a Dec 31 FYE Company)

Let’s take a company with a Financial Year End (FYE) of 31 December 2025:

1. Financial Year: 1 Jan 2025 – 31 Dec 2025

2. ECI Filing (by ~31 Mar 2026): The company calculates its estimated profit for 2025 and files its ECI.

3. Year of Assessment (YA): YA 2026 (this is the year you are being assessed for the income earned in 2025).

4. Form C-S/C Filing (by 30 Nov 2026): The company finalizes its accounts and files the full tax return (Form C-S or C) for YA2026.

5. Notice of Assessment (NOA): IRAS issues the NOA, which is the final tax bill.

6. Tax Payment: The deadline for payment is typically one month after the date on the NOA.

Key Concepts to Understand

• Year of Assessment (YA): The year in which income is assessed and taxed. It always follows the calendar year after the financial year in which the income was earned.

• Chargeable Income: This is your taxable profit, calculated as:

  • • Revenue minus Allowable Business Expenses minus Capital Allowances (instead of depreciation) minus Trade Losses & Donations.

• Corporate Tax Rate:

  • Standard Rate: 17%

  • Partial Tax Exemption & Start-Up Tax Exemption: Most companies benefit from these schemes, which significantly reduce the effective tax rate on their first S$300,000 of chargeable income. For example, a new start-up can enjoy 0% tax on its first S$100,000 of chargeable income for its first three consecutive YAs.

• Taxable and Non-Taxable Income: Only income accrued in or derived from Singapore is taxable. Certain types of foreign-sourced income can be exempt if specific conditions are met.

Compliance Checklist for Companies

1. Maintain Proper Records: Keep all financial statements, receipts, invoices, and supporting documents for at least 5 years.

2. Appoint a Corporate Tax Agent: Most companies hire a qualified accountant or corporate service provider to handle the preparation and filing. This is highly recommended to ensure compliance and optimize tax positions.

3. Know Your Deadlines: Mark your calendar for the ECI (3 months after FYE) and the annual return (30 Nov).

4. Use IRAS myTax Portal: All filings are done electronically via IRAS’ secure online portal.

Consequences of Non-Compliance

Failure to file tax returns by the deadline can result in:

• Penalties: A composition amount (fine).

• Estimated Notice of Assessment (NOA): IRAS may raise an estimated tax bill, which is often higher than the actual amount.

• Legal Action: In severe cases, court prosecution.
