Corporate Tax Rates and Deductions in Singapore

Singapore follows a single-tier corporate tax system, meaning the tax paid by companies on their profits is final. In other words, Singapore does not impose taxes on dividends that are paid to the company’s owners. The standard corporate tax rate is 17%. However, numerous deductions and exemptions can lower the effective tax rate significantly.

Deduction for New Companies

New start-up companies benefit from the Start-Up Tax Exemption (SUTE) scheme. For the first three consecutive years of assessment, a newly incorporated company can enjoy 75% exemption on the first SGD 100,000 of normal chargeable income and a further 50% exemption on the next SGD 100,000.

When to File Tax Declaration

The annual tax return must be filed with the Inland Revenue Authority of Singapore (IRAS) by November 30th for paper filing and by December 15th for electronic filing. This includes Form C-S/C, which details the company’s income, deductions, and exemptions.

When to File Estimated Taxable Income (ECI)

The Estimated Chargeable Income (ECI) must be filed within three months from the end of the financial year. The ECI declaration helps IRAS determine the company’s tax payable in advance.
