Singapore's flat 17% corporate tax rate, combined with partial exemptions, makes the effective rate on smaller profits significantly lower.
| Chargeable Income | Exemption |
|---|---|
| First $10,000 | 75% exempt |
| Next $190,000 | 50% exempt |
| Above $200,000 | Full 17% rate applies |
New companies get a more generous exemption for their first 3 YAs: 75% exemption on the first $100,000, and 50% on the next $100,000 — subject to shareholder eligibility conditions.
Companies file an Estimated Chargeable Income (ECI) within 3 months of financial year-end, and a full tax return (Form C-S/C-S Lite/C) by 30 November each year (for the prior financial year).
