What is the corporate income tax rate in Singapore?

The Singapore corporate income tax rate is a flat 17% of chargeable income. However, the start-up tax exemption or partial tax exemption can generally apply, so the effective tax rate may be lower than this.

Chargeable income is generally revenue minus expenses allowed under tax law. Which exemption applies depends on whether the company meets the conditions.

• Start-up tax exemption (first three Years of Assessment for qualifying companies): 75% of the first S$100,000 of chargeable income and 50% of the next S$100,000 may be exempt. It applies to companies that meet the conditions set by IRAS, such as having no more than 20 shareholders who hold the shares directly.
• Partial tax exemption (other companies): 75% of the first S$10,000 of chargeable income and 50% of the next S$190,000 may be exempt.
• Corporate income tax rebate: Rebates are sometimes given for particular years depending on the government budget, so please check based on the year of filing.

Tax treatment can differ depending on the company's revenue, shareholder structure and transactions, so please consult an accounting professional before applying it.
