Singapore's corporate tax rate is a flat 17%, one of the lowest in Asia and a key reason the country remains a preferred base for regional headquarters and holding structures. Few companies pay that full rate in practice. Exemption schemes, rebates, and a territorial tax system bring most foreign-owned businesses well below 17% in their early years.
This guide covers how corporate tax in Singapore applies to foreign companies, from the rate and exemptions to tax residency and filing deadlines.
Who Pays Corporate Tax in Singapore?
Corporate tax applies to any company incorporated in Singapore, regardless of where its shareholders are based. It also applies to foreign companies with a taxable presence in Singapore, such as a branch. The structure you use determines how much of that tax you actually owe.
- Private Limited Company (Pte Ltd): A separate legal entity from its foreign parent. It pays tax on its own chargeable income and can access exemptions like the Start-up Tax Exemption, provided it also meets Singapore's tax residency conditions. For most foreign companies planning to trade or generate revenue in Singapore, this is the structure that unlocks the tax advantages covered below.
- Branch Office: An extension of its foreign parent rather than a separate entity. It's taxed only on Singapore-sourced income, but IRAS automatically treats it as a non-resident. That rules out the Start-up Tax Exemption and most Double Taxation Agreement benefits, since both require Singapore tax residency.
A representative office doesn't pay corporate tax because it isn't permitted to generate revenue. It's limited to market research and liaison activities, so it falls outside the corporate tax system entirely.
Corporate Income Tax (CIT): Structure and Rates
The scope of your Corporate Income Tax liability depends on tax residency and where your income comes from, not on worldwide profit. Both resident and non-resident companies are taxed on income accrued in or derived from Singapore, and on foreign income once it's received here.
If you're a foreign company without a Permanent Establishment (PE) in Singapore, your Singapore-sourced income generally falls outside standard CIT. Certain payments, instead, such as royalties, technical assistance fees, and management fees, get taxed through withholding tax, which we cover later in this guide.
Once your business triggers CIT liability, three structural features shape what you actually pay.
- Flat 17% Rate: Singapore taxes chargeable income at a flat 17%, with no tax brackets. A company earning S$50,000 and one earning S$5 million both start from the same rate before any exemption applies, unlike countries that scale their rate as profits grow.
- One-Tier System: Once a company pays CIT on its chargeable profits, those profits are cleared of further tax. Dividends distributed to shareholders, individual or corporate, local or foreign, arrive completely tax-free.
- No Capital Gains Tax: Profit from selling a company asset, a subsidiary stake, or intellectual property is generally exempt, provided the gain is genuinely capital in nature rather than income from trading. IRAS can treat frequent or short-term disposals as trading income instead, taxed at the standard 17% rate.
These features form a large part of why foreign companies use Singapore as a holding company jurisdiction for regional structures.
Tax Residency and the Control and Management Test
Singapore tax residency depends on where the control and management of the business happen. This specifically refers to where your board of directors meets and makes strategic decisions.
If the board meets in Singapore, the company is generally a Singapore tax resident, even if every shareholder is based overseas. But if the board meets and decides from another country instead, a Singapore-incorporated company can be treated as non-resident. That removes access to the Start-up Tax Exemption, treaty benefits, and the Certificate of Residence needed to claim relief under Singapore's Double Taxation Agreements.
Exemptions and How to Calculate CIT
The headline 17% rate rarely reflects what a company actually pays in its early years. Two schemes bring the effective rate down further:
- Start-up Tax Exemption (SUTE): For a company's first three Years of Assessment, exempting 75% of the first S$100,000 of chargeable income and 50% of the next S$100,000. Eligibility requires Singapore incorporation, tax residency, no more than 20 shareholders, and at least one individual shareholder holding 10% or more of the issued ordinary shares. Investment holding and property development companies are excluded.
- Partial Tax Exemption (PTE): Applies once SUTE's three years end, or from the start for companies that don't qualify for SUTE. It exempts 75% of the first S$10,000 of chargeable income and 50% of the next S$190,000.
The government periodically issues Corporate Income Tax Rebates on top of SUTE or PTE to support cash flow. Rebate amounts change by Year of Assessment. Emerhub can confirm the current figure for your filing year rather than assuming a previous year's rate still applies.
We cover this in more detail in our Guide to Tax Exemptions for New Companies in Singapore.
To calculate CIT, start with chargeable income, apply the relevant exemption, and tax the remainder at 17%. Here's how this works for a newly incorporated foreign-owned company under SUTE:
| Calculation Step | Description | Amount (SGD) |
|---|---|---|
| Chargeable Income | Profit after allowable deductions | 150,000 |
| SUTE Exemption (first S$100,000) | 75% exempt | (75,000) |
| SUTE Exemption (next S$50,000) | 50% exempt | (25,000) |
| Taxable Income | Chargeable income after exemption | 50,000 |
| Tax Due (17% rate) | Applied to taxable income | 8,500 |
| Effective Tax Rate | Tax due ÷ chargeable income | 5.7% |
Working out which exemption applies to your structure, or whether your shareholding qualifies for SUTE, takes local knowledge of the current conditions in Singapore. Emerhub's local accounting team can review your structure and file your exemption claims correctly.
Goods and Services Tax (GST) in Singapore
Singapore's Goods and Services Tax (GST) works differently from Corporate Income Tax. It's a tax on revenue rather than profit, so a company can owe GST in a loss-making year, and registration depends on turnover rather than tax residency.
GST is Singapore's consumption tax, charged on the supply of goods and services and on imports. The current rate is 9% (in effect since 1 January 2024) and administered by IRAS.
GST Registration Thresholds
Registration becomes compulsory once a company's taxable turnover exceeds S$1 million, tested in two ways:
- Under the retrospective view, a company checks its taxable turnover for the past calendar year.
- Under the prospective view, a company assesses whether it can reasonably expect to exceed S$1 million in the next 12 months.
Meeting either test triggers a registration obligation. Companies below the threshold can register voluntarily. This typically appeals to exporters and businesses that sell mainly to GST-registered customers, since voluntary registrants commit to staying registered for at least two years.
Starting 1 April 2026, all new voluntary GST registrants must transmit invoice data to IRAS through the InvoiceNow network. The requirement extends to all GST-registered businesses in phases through 2031.
How to Calculate GST in Singapore
GST-registered companies charge output GST on sales and can claim input GST paid on business purchases. The net amount (output minus input) is what gets remitted to IRAS.
Below is an example of a services company charging the standard 9% rate:
| Item | Calculation | Amount (SGD) |
|---|---|---|
| Total Sales (Excl. GST) | Revenue from services rendered | 500,000 |
| Output GST (9%) | Tax collected from customers | 45,000 |
| Input Purchases (Excl. GST) | Cost of goods and services bought | 200,000 |
| Input GST (9%) | Tax paid to suppliers | (18,000) |
| Net GST Payable | Output GST minus Input GST | 27,000 |
GST returns are filed quarterly, within one month after the end of each accounting period.
Withholding Tax for Companies in Singapore
Withholding tax applies when a Singapore company makes certain payments to a non-resident either as an individual or a business entity. The company making the payment is the payer, and carries the compliance obligation.
If your Singapore company pays interest, royalties, or service fees to an overseas party, you deduct the tax before the payment goes out. You then remit that amount to IRAS, even when the recipient has no presence in Singapore.
Common Payments and Rates
| Payment Type | Withholding Tax Rate |
|---|---|
| Interest on loans | 15% (final tax) |
| Royalties | 10% (final tax) |
| Technical assistance and management fees for services performed in Singapore | Prevailing corporate rate (17%) |
| Rent for movable property | 15% |
| Fees to non-resident directors | 24% |
| Payments to non-resident professionals | 15% |
Dividends paid by a Singapore company are not subject to withholding tax under the one-tier system.
DTA Relief and Certificate of Residence
Singapore has agreements with more than 100 countries that reduce these standard rates. For example, the Singapore-Malaysia treaty lowers withholding tax on interest from 15% to 10%.
To apply a reduced rate, the non-resident recipient needs a valid Certificate of Residence from their home tax authority, obtained before payment or by the filing deadline. Without it, the standard domestic rate applies regardless of what the treaty allows.
Withholding tax is filed on Form S45 and is due by the 15th of the second month following the date of payment. Missing this deadline adds a 5% penalty, rising over time.
How to Calculate Withholding Tax in Singapore
To calculate withholding tax, apply the relevant rate to the gross payment, not to a net figure.
Here's an example of a Singapore company paying a non-resident consultant S$20,000 for technical services performed in Singapore:
| Item | Amount (SGD) |
|---|---|
| Gross Payment | 20,000 |
| Withholding Tax Rate (prevailing corporate rate) | 17% |
| Tax Withheld | 3,400 |
| Net Payment to Consultant | 16,600 |
The company remits S$3,400 to IRAS and pays the consultant the remaining S$16,600. This filing is due on Form S45 by the 15th of the second month following the date of payment. Missing this deadline adds a 5% penalty, rising over time.
Corporate Tax Filing Calendar in Singapore
CIT, GST, and withholding tax each run on their own filing track, and the deadlines don't align with each other. A company can stay current on one obligation and still miss another. The table below consolidates every deadline covered in this guide.
| Filing | Deadline | Key Action |
|---|---|---|
| Estimated Chargeable Income (ECI) | Within 3 months of financial year-end | File a forecast of taxable income for the year |
| GST F5 Return | Within 1 month after each quarter | File and pay net GST for GST-registered companies |
| Withholding Tax (Form S45) | 15th of the second month after payment | File and remit tax withheld on payments to non-residents |
| Form C-S (Lite) / Form C-S / Form C | 30 November | File the final annual corporate tax return |
| Tax Payment | Within 1 month of Notice of Assessment | Pay the amount IRAS assesses as owing |
The ECI exemption (available when annual revenue is S$5 million or below and ECI is zero for the Year of Assessment) requires both conditions to be met. Companies that assume exemption without checking both often end up filing late.
Company incorporation also brings ACRA and CPF obligations, including the Annual Return, AGM, and employee-related filings. Read our guide on Singapore’s Annual Compliance Calendar for the complete list.

Frequently asked questions
What counts as foreign-sourced income for a Singapore company?
Foreign-sourced income refers to income that doesn't arise from a trade or business carried on in Singapore. This includes dividends from an overseas subsidiary, profits from a foreign branch, or service fees earned through a fixed place of operation abroad. This income sits outside Singapore's tax net until it's brought into the country, unlike Singapore-sourced income, which is taxed as it accrues.
Does a foreign company have to pay tax in Singapore if it has no physical office there?
Your company is only subject to Singapore corporate tax if its income is derived from or accrued in Singapore, or if foreign-sourced income is received there. If your business operates entirely outside Singapore, has no local permanent establishment, and does not conduct business activities within the country, you generally will not owe Singapore corporate tax. However, you must ensure that your operations do not inadvertently create a tax nexus or permanent establishment under Singapore law.
What happens if I file my Singapore corporate tax returns late?
If you miss the filing deadlines, IRAS will issue a penalty notice. The late filing fee typically ranges from $200 to $1,000 depending on how late the filing is. In serious cases of non-compliance, IRAS may issue a summons to the company directors, estimate your company's tax and issue a Notice of Assessment based on that estimate, or take legal action. Working with a professional corporate services provider ensures you never miss a deadline.
Are dividends paid to foreign shareholders subject to withholding tax?
Singapore does not levy any withholding tax on dividends distributed to shareholders, regardless of whether those shareholders are individuals or corporate entities, local or foreign. Because Singapore operates under a single-tier corporate tax system, all corporate tax is paid at the company level. Once that tax is paid, profits can flow to shareholders completely tax-free.
Can my company carry forward business losses to offset future taxes?
Singapore allows companies to carry forward their unused trade losses and capital allowances indefinitely to offset taxable profits in future years. To qualify for this carry-forward, your company must pass the Shareholder Test. This test requires that there is no substantial change in your company's shareholders and their shareholdings (specifically, a change of less than 50%) on relevant comparison dates.
