Corporate Income Tax: Rates, Exemptions & Filing
Singapore's competitive corporate tax framework — rates, exemption schemes, rebates and filing obligations explained in plain language.
Singapore maintains one of the most competitive corporate tax regimes in Asia. All companies — whether locally incorporated or operating as a branch — are taxed at a flat rate of 17% on their chargeable income. Corporate income tax is assessed on a preceding-year basis, meaning income earned in financial year 2024 is assessed in Year of Assessment (YA) 2025.
Tax Exemption Schemes
Start-Up Tax Exemption (first 3 YAs)
75% exemption on first S$100,000; 50% on next S$100,000 of chargeable income
Partial Tax Exemption (from 4th YA onwards)
75% exemption on first S$10,000; 50% on next S$190,000 of chargeable income
CIT Rebate (YA 2026)
40% rebate on tax payable, minimum S$1,500 benefit (with at least 1 local employee in 2025), capped at S$30,000
Key Filing Obligations

File within 3 months of your financial year end. Companies with annual revenue ≤ S$5 million and nil ECI may qualify for a filing waiver.
