Rate
A company pays corporate income tax at a flat 17% of its chargeable income. This applies to local and foreign companies.
Tax exemptions
A company uses one of these on its normal chargeable income (income taxed at 17%), YA 2020 onwards:
| Scheme | First band | Next band | Most exempt a year |
|---|---|---|---|
| Start-up exemption (first 3 YAs) | 75% of the first $100,000 | 50% of the next $100,000 | $125,000 |
| Partial exemption (all other companies) | 75% of the first $10,000 | 50% of the next $190,000 | $102,500 |
To claim the start-up exemption a company must be incorporated and tax resident in Singapore, have no more than 20 shareholders throughout the year (all individuals, or at least one individual holding 10% or more of the ordinary shares), and not be an investment holding or property development company. IRAS audits abuse through shell companies.
YA 2026 CIT Rebate and Cash Grant
For YA 2026 every taxpaying company gets a CIT Rebate of 50% of the corporate tax payable. An active company that made CPF contributions for at least one local employee (not a shareholder-director) in 2025 also gets a $2,000 CIT Rebate Cash Grant, paid automatically and not taxable. The two together are capped at $40,000.
| Company | How the rebate works |
|---|---|
| Eligible for the Cash Grant | If the rebate is $2,000 or less, no rebate is given (the grant is the benefit); otherwise the rebate, capped at $40,000, less $2,000 |
| Not eligible | The rebate, capped at $40,000 |
The rebate is applied after the exemptions. It does not apply to income under a final withholding tax.
