What is the Singapore corporate tax rate for 2026?
The Singapore corporate income tax rate for YA2026 is 17%. However, most Singapore-incorporated companies pay a significantly lower effective rate because of the Start-Up Tax Exemption (first 3 YAs) or the Partial Tax Exemption (YA4 onwards). A profitable startup earning S$300,000 effectively pays around 9.9%.
Singapore's 17% headline rate is one of the lowest in Asia-Pacific. Combined with the SUTE and PTE schemes, effective tax rates for small and medium companies are substantially lower — making Singapore one of the most tax-efficient jurisdictions for incorporating a business.
What is the difference between SUTE and PTE?
SUTE is for new companies in their first three Years of Assessment — it exempts 75% of the first S$100,000 and 50% of the next S$100,000. PTE applies from YA4 onwards to all qualifying companies — it exempts 75% of the first S$10,000 and 50% of the next S$190,000. SUTE gives larger savings at lower income levels; at higher income levels, the difference narrows.

What counts as chargeable income in Singapore?
Chargeable income is your net profit after deducting all allowable business expenses from revenue. Common allowable deductions include staff costs and CPF, rent, professional fees, capital allowances on equipment, and trade debts written off. Non-deductible items include private expenses, fines, capital expenditure, and expenses not wholly for business.
Accurate financial statements are the foundation of a correct tax filing. If your bookkeeping is incomplete or expenses are miscategorised, your chargeable income will be wrong — either overstating tax owed (you lose cash) or understating it (you risk an IRAS audit). This is why clean, monthly bookkeeping directly reduces your tax risk.
Who files and pays corporate tax in Singapore?
Corporate income tax is filed with IRAS by a licensed tax agent or filing agent — not your bookkeeper or accountant. Your accountant's role is to prepare accurate financial statements and management accounts so your tax agent can compute the correct chargeable income and file on time.
The ECI (Estimated Chargeable Income) must be filed within 3 months of your financial year end. The full Form C-S (for companies with revenue under S$5M) or Form C is due by 30 November. Your bookkeeper provides the numbers; your tax agent does the filing. Keep the two roles clear.
Frequently asked questions
Can a startup claim SUTE if it has a corporate shareholder?
No. SUTE requires that all shareholders are individuals, or at least one individual shareholder holds at least 10% of shares, during the first three YAs. If a corporate entity owns 100% of shares, SUTE does not apply. However, PTE (partial exemption) still applies from the first YA in that case.
What happens if my company makes a loss?
If your chargeable income is zero or negative, no corporate tax is payable. Unutilised capital allowances and trade losses can be carried forward indefinitely to offset future taxable income, subject to the same business ownership condition. They can also be carried back one YA under the loss carry-back relief, up to S$100,000.
Is dividend income taxable in Singapore?
Singapore operates a one-tier tax system. Once corporate tax has been paid on a company's profits, dividends distributed to shareholders are exempt from further tax. Shareholders — whether individuals or companies — do not pay tax on dividends received from Singapore-resident companies.
Do I need audited accounts to file corporate tax?
Companies that qualify for audit exemption (revenue under S$10M, assets under S$10M, fewer than 50 employees — any 2 of 3) do not need statutory audits. Unaudited financial statements prepared to SFRS standards are sufficient for tax filing purposes, provided they are accurate and complete.
