What is the corporate tax rate in Singapore for 2026? The headline corporate tax rate is 17%. However, qualifying new companies can achieve an effective tax rate as low as 4.25% on their first S$100,000 of chargeable income through the Startup Tax Exemption (SUTE) scheme. Additionally, eligible companies can claim a 40% corporate tax rebate (capped at S$40,000) to further reduce their final tax payable. All companies, including dormant ones, must file their annual Form C-S by November 30.
17%
4.25% (First S$100k)
40% (Capped at S$40k)
Key Takeaways for Singapore Companies
- SUTE is Not "Zero Tax": The Startup Tax Exemption provides a 75% exemption on the first S$100,000 (effective 4.25% rate) and a 50% exemption on the next S$100,000 (effective 8.5% rate).
- Rebate Cap is S$40,000: The 40% corporate tax rebate is capped at S$40,000 per Year of Assessment. It reduces your final tax bill, but does not result in a refund if your company is loss-making.
- Dormant Companies Must Still File: Even if your company had no business transactions or incurred a loss, you must file a Form C-S or apply for a formal waiver of filing with IRAS to avoid penalties.
- Withholding Tax is Separate: While corporate tax applies to your profits, payments to overseas vendors may trigger withholding tax obligations. For a complete breakdown of WHT rates and Form IR37 filing, see our dedicated Singapore Withholding Tax Guide.

The 2026 Corporate Tax Landscape: Rates & Rebates
Singapore maintains one of the most competitive and transparent corporate tax regimes globally, with a flat headline rate of 17% on chargeable income. However, the effective tax rate for most small and medium-sized enterprises (SMEs) is significantly lower due to targeted government incentives.
The most impactful incentive for the 2025 and 2026 Years of Assessment (YA) is the 40% Corporate Tax Rebate. This rebate is applied directly to your final tax payable, capped at a maximum of S$40,000 per company. For a detailed breakdown of how this rebate interacts with other grants, see our analysis of the Singapore Budget 2026 tax rebate and AI grants.
How the Startup Tax Exemption (SUTE) Actually Works
A common misconception is that new companies pay "zero tax" in their first three years. This is inaccurate. Under the Startup Tax Exemption (SUTE) scheme, eligible new companies receive partial exemptions, resulting in a highly favorable, but not zero, effective tax rate.
| Chargeable Income Bracket | Exemption Level | Effective Tax Rate |
|---|---|---|
| First S$100,000 | 75% exempt | 4.25% (on the remaining 25%) |
| Next S$100,000 | 50% exempt | 8.5% (on the remaining 50%) |
| Above S$200,000 | 0% exempt | 17% (Standard headline rate) |
To qualify for SUTE, your company must be incorporated in Singapore, be a tax resident for the relevant YA, have no more than 20 shareholders (all of whom must be individuals, or at least one individual holding ≥10% of the shares), and not be formed for the purpose of holding investment properties or carrying out investment holding activities.
Filing Deadlines You Cannot Miss in 2026
IRAS enforces strict deadlines for corporate tax filings. Missing these dates triggers automatic penalties, regardless of whether your company made a profit or a loss.
- Estimated Chargeable Income (ECI): Must be filed within 3 months of your financial year-end (FYE). You may be exempt from filing ECI only if your annual revenue is ≤ S$5 million and your ECI is nil.
- Form C-S / Form C-S Lite: The final corporate tax return must be filed by 30 November of the Year of Assessment. Form C-S Lite is a simplified version available for companies meeting specific criteria (e.g., annual revenue ≤ S$500,000).
- Dormant Companies: If your company had no accounting transactions during the financial year, you must still notify IRAS. You can apply for a waiver of income tax return filing to avoid the administrative burden, but this waiver must be explicitly granted by IRAS.
⚠️ The Cost of Late Filing
IRAS does not offer a grace period for late tax filings. Consequences include:
- Immediate Penalties: A late filing penalty ranging from S$200 to S$600, depending on the delay.
- Estimated Notice of Assessment (NOA): IRAS will estimate your tax liability based on industry benchmarks, which is often higher than your actual tax, and demand immediate payment.
- Legal Action: Persistent non-compliance can lead to prosecution of the company's directors.
Common Corporate Tax Mistakes to Avoid
Based on our experience managing hundreds of corporate tax filings, these are the most frequent and costly errors Singapore businesses make:
- Misclassifying SUTE Eligibility: Assuming a newly incorporated investment holding company qualifies for SUTE. It does not. Investment holding companies are explicitly excluded from the scheme.
- Ignoring Dormant Filing Requirements: Assuming that "no business activity" means "no filing required." Without an approved IRAS waiver, failing to file a dormant return incurs the same penalties as an active company.
- Confusing GST with Corporate Tax: Treating GST collection and remittance as part of your corporate tax filing. They are entirely separate obligations with different forms (Form F5 for GST, Form C-S for corporate tax) and deadlines. For a complete breakdown of your indirect tax obligations, refer to our Ultimate GST Compliance Guide.
- Overlooking Unclaimed Capital Allowances: Failing to claim capital allowances on qualifying assets (e.g., computers, automation equipment) in the year of purchase, thereby unnecessarily inflating your chargeable income.
