Corporate Tax

One of the most compelling reasons to incorporate a company in Singapore is the Start-Up Tax Exemption (SUTE) — a generous scheme that can significantly reduce your corporate tax bill in the first three years of operation. But to make the most of it, you need to plan ahead. The Start-Up Tax Exemption (SUTE) Under the Start-Up Tax Exemption scheme, newly incorporated Singapore companies can enjoy full and partial tax exemption on their chargeable income for the first three Years of Assessment (YAs). This is one of the most generous startup incentives in the region. Who Qualifies? To qualify for SUTE, your company must meet all of the following conditions: 💡 Investment holding companies and companies whose principal activity is to develop and license intellectual property are not eligible for SUTE.

Every incorporated company in Singapore is required to file a corporate income tax return with the Inland Revenue Authority of Singapore (IRAS) each year. But there are two forms — Form C and Form C-S — and filing the wrong one (or missing the deadline) can result in penalties. Who Needs to File? All companies incorporated in Singapore — including dormant companies and companies with no income — must file a corporate income tax return (Form C or Form C-S) with IRAS every year. Filing is mandatory regardless of whether your company made a profit. 💡 Even if your company made a loss or had zero revenue, you are still required to file. Non-filing attracts penalties and IRAS may issue estimated assessments. What is Form C-S? Form C-S is a simplified version of the corporate tax return, designed for small companies. It is a 3-page document that contains fewer fields and no requirement to attach financial statements or tax computation to IRAS — though you must still prepare and retain these records. Your company qualifies for Form C-S if it meets all three criteria: What is Form C? Form C is the full corporate income tax return. It is more comprehensive and requires companies to submit the return together with financial statements, tax computation, and supporting schedules. Your company must file Form C if it does not qualify for Form C-S — for example if your revenue exceeds S$5 million, if you have tax adjustments to declare, or if you are claiming specific reliefs not available under Form C-S.
