Understanding the corporate tax rate in Singapore is essential for any company planning to incorporate or expand here. Singapore is one of the world’s most business-friendly jurisdictions, thanks to a simple, single-tier tax system, a low headline rate, and generous exemptions and rebates for startups and small companies.
The most common question from local and foreign entrepreneurs is simple: what is the corporate tax rate in Singapore, and what will a company actually pay after exemptions? The headline rate is a flat 17% on chargeable income, but most small and medium companies pay a far lower effective rate once start-up or partial exemptions and the current Corporate Income Tax (CIT) Rebate are applied.
This guide covers the YA 2026 position: the headline rate, the exemption schemes, the YA 2026 CIT Rebate, how tax is calculated, the effective rate you can expect, and the filing deadlines every Singapore company must meet. All figures are current for the Year of Assessment (YA) 2026 and sourced from the Inland Revenue Authority of Singapore (IRAS).
Key Facts: Singapore Corporate Tax (YA 2026)
- Headline corporate tax rate: a flat 17% on chargeable income, for both local and foreign companies (IRAS).
- YA 2026 CIT Rebate: 50% of corporate tax payable, capped at S$40,000 (less the S$2,000 cash grant where applicable), per IRAS.
- CIT Rebate Cash Grant: a minimum S$2,000 for active companies that employed at least one local employee (with CPF contributions) in 2025.
- Start-Up Tax Exemption (SUTE): 75% off the first S$100,000 and 50% off the next S$100,000 of chargeable income — up to S$125,000 exempt per year for the first 3 years.
- Partial Tax Exemption (PTE): 75% off the first S$10,000 and 50% off the next S$190,000 — up to S$102,500 exempt per year.
- Tax system: territorial and single-tier — only Singapore-sourced or remitted income is taxed, and dividends are tax-free in shareholders’ hands.
- Filing deadline: the YA 2026 Corporate Income Tax Return (Form C-S / Form C-S (Lite) / Form C) is due by 30 November 2026.
What Is the Corporate Tax Rate in Singapore?
Singapore imposes a flat corporate tax rate of 17% on chargeable income — one of the most competitive headline rates in Asia. Unlike progressive personal income tax, this single rate applies uniformly to every company regardless of size, revenue, or ownership. That simplicity and predictability is a large part of why Singapore attracts so much regional investment.
Key highlights:
- Flat-rate system: 17% on chargeable income, after deducting allowable business expenses, capital allowances, and reliefs.
- Territorial basis: only income sourced in Singapore, or foreign income remitted to Singapore, is taxable.
- No capital gains tax: profits from the sale of assets or shares are not subject to corporate income tax.
- Single-tier system: tax is paid once, at the company level; dividends distributed to shareholders are exempt.
By comparison, headline corporate tax rates in many developed economies sit above 25%, so Singapore’s 17% — before exemptions — is highly competitive for companies planning long-term operations in Asia.
Years of Assessment: What “YA 2026” Means
Singapore taxes companies on a preceding-year basis. The Year of Assessment (YA) is the year in which income earned in the previous financial year is assessed and taxed. So YA 2026 covers the profits of the financial year ending in 2025. When you read “YA 2026 rates and rebates”, these apply to the income your company earned in its 2025 financial year and reports to IRAS in 2026. Knowing which YA you are filing for matters, because exemptions and rebates are set per YA.
Corporate Income Tax Rebate for YA 2026
On top of the exemption schemes, the Singapore Government grants a Corporate Income Tax (CIT) Rebate in selected years to ease business costs. For YA 2026, IRAS has confirmed a CIT Rebate of 50% of the corporate tax payable, capped at S$40,000 (reduced by the S$2,000 cash grant where a company receives it).
In addition, a CIT Rebate Cash Grant of S$2,000 is given to active companies that met the “local employee condition” — that is, made CPF contributions for at least one local (Singapore Citizen or Permanent Resident) employee in 2025. Eligible companies receive the cash grant automatically, and it is not taxable. Full details and worked examples are published by IRAS. Rebate amounts change from year to year, so always confirm the figure for the YA you are filing.
Singapore Corporate Tax Exemptions: SUTE and PTE
Although the headline rate is 17%, most companies pay less because of two exemption schemes. Together with the CIT Rebate, these are the main reasons Singapore’s effective corporate tax rate is so low for smaller companies.
1. Start-Up Tax Exemption (SUTE)
For its first three consecutive Years of Assessment, a qualifying new company gets:
- 75% exemption on the first S$100,000 of normal chargeable income; and
- a further 50% exemption on the next S$100,000.
That is up to S$125,000 of chargeable income exempted each year, which can pull the effective rate below 5% in the early years. To qualify, a company must be incorporated and tax-resident in Singapore, have no more than 20 shareholders (all individuals, or at least one individual holding at least 10% of shares), and must not be an investment-holding or property-development company.
2. Partial Tax Exemption (PTE)
Once a company is past the start-up phase (or does not qualify for SUTE), it receives partial tax exemption:
- 75% exemption on the first S$10,000 of normal chargeable income; and
- a further 50% exemption on the next S$190,000.
That is up to S$102,500 exempted each year. All companies, including companies limited by guarantee, are eligible for PTE unless they are claiming SUTE. Exemption figures are set by IRAS and apply from YA 2020 onwards.
Headline vs Effective Corporate Tax Rate
The 17% headline rate is rarely what a small company actually pays. After exemptions, the effective rate is much lower. For a new company in its first three YAs claiming SUTE:
- the first S$100,000 of chargeable income is taxed at an effective 4.25% (75% exempt);
- the next S$100,000 is taxed at an effective 8.5% (50% exempt); and
- chargeable income above S$200,000 is taxed at the full 17%.
Apply the YA 2026 CIT Rebate on top, and the cash tax payable falls further still. This is why the “real” corporate tax burden for most Singapore SMEs is well below the 17% headline.
How to Calculate Corporate Income Tax in Singapore
To estimate tax, companies use a Singapore corporate tax calculator or work with corporate service providers. The general formula is:
Chargeable Income = Taxable Revenue − Allowable Deductions − Capital Allowances − Reliefs.
Worked example (established company, PTE applies):
- Revenue: S$1,000,000.
- Deductible business expenses: S$200,000.
- Capital allowances: S$50,000.
- Chargeable income: S$750,000.
- Gross tax at 17%: S$127,500 (before exemptions and rebate).
Applying the partial tax exemption and the YA 2026 CIT Rebate reduces this liability significantly. For a precise figure, use the IRAS Basic Corporate Income Tax Calculator or speak to a tax adviser.
Filing and Payment: ECI, Form C-S/C, and Deadlines
Every Singapore company must meet two filing obligations each year, even if it made a loss or was dormant.
- Estimated Chargeable Income (ECI): file within 3 months of the financial year-end (unless the company qualifies for the ECI waiver).
- Form C-S / Form C-S (Lite) / Form C: the annual Corporate Income Tax Return, due by 30 November 2026 for YA 2026. This is a fixed calendar deadline — it is not based on your financial year-end anniversary.
- Payment: corporate tax is generally payable within 1 month of the Notice of Assessment, though GIRO instalment options are available.
Losses can be carried forward (subject to conditions), and group relief allows qualifying companies to offset losses within the same group. Missing filing deadlines can trigger penalties, so most companies engage corporate tax filing services to stay compliant.
Corporate Tax for Foreign-Owned Companies
Foreign investors often ask whether their Singapore company is taxed differently. It is not: every company incorporated in Singapore pays the same flat 17% rate, regardless of ownership.
A few points matter for foreign-owned companies. Foreign-sourced income may be exempt from Singapore tax when certain conditions are met, including that the income was already taxed in the foreign jurisdiction. Singapore also has an extensive network of Avoidance of Double Taxation Agreements (DTAs) that help prevent the same income being taxed twice across borders. And because Singapore operates a single-tier system with no dividend withholding tax, profits distributed as dividends are not taxed again in the shareholders’ hands — a key reason Singapore is a favoured holding-company location. Companies expanding here often pair tax planning with company registration for foreigners and GST planning.
Do You Need to Register for GST?
Corporate income tax is separate from Goods and Services Tax (GST). A company must register for GST once its taxable turnover exceeds the registration threshold, and voluntary registration is possible below it. If you are approaching that turnover, read our guide on when to register for GST in Singapore before you file.
Benefits of Singapore’s Corporate Tax System
Singapore’s tax framework offers more than a low rate — it offers certainty and clear rules. Compliance is straightforward under IRAS guidance, and companies can access incentives for activities such as R&D, global trading, and regional headquarters. Combined with the exemption schemes, the CIT Rebate, and an extensive treaty network, this makes Singapore particularly attractive for startups, SMEs, and foreign investors building a regional base.
Conclusion
Singapore’s corporate tax rate — a flat 17%, softened by the SUTE and PTE exemptions and the YA 2026 CIT Rebate — remains one of the country’s biggest advantages as a business hub. For most SMEs, the effective rate is well below the headline figure, and the filing calendar is predictable: ECI within three months of year-end, and the return by 30 November.
Whether you are incorporating locally or expanding into Asia, getting the tax position right from day one protects your cash flow and keeps you compliant. If you would like help estimating your liability or filing on time, SBC’s Singapore tax team can handle it end to end.
