Corporate tax exemptions and partial-exemption scheme — Timeline and processing benchmarks

Singapore’s corporate tax exemptions and partial-exemption scheme reduce the effective tax rate for companies, especially smaller and newer ones, below the headline 17% rate. Qualifying new companies can exempt a large slice of their first S$200,000 of chargeable income, while the partial-exemption scheme benefits all companies. This 2026 guide explains eligibility, the numbers and the filing timeline.

The headline rate and why exemptions matter

Singapore levies corporate income tax at a flat 17% on chargeable income. On its own that is competitive, but the effective rate for most small and medium companies is materially lower because of two exemption schemes layered on top: the Start-up Tax Exemption (SUTE) for qualifying new companies and the Partial Tax Exemption (PTE) available to all companies. Both are provided for under the Income Tax Act 1947.

These exemptions are automatic in the sense that IRAS applies them when a company files, but eligibility for the start-up scheme in particular depends on conditions that a company can inadvertently fail, so understanding them is part of prudent tax planning.

The Start-up Tax Exemption scheme

Under SUTE, a qualifying company enjoys, for each of its first three consecutive years of assessment, a 75% exemption on the first S$100,000 of normal chargeable income and a further 50% exemption on the next S$100,000. That shelters a significant portion of early profits when cash is tightest.

To qualify, the company must be incorporated in Singapore, be a tax resident for that year of assessment, and have no more than 20 shareholders throughout the basis period, with all shareholders being individuals or at least one individual shareholder holding at least 10% of the ordinary shares. Property and investment holding companies are excluded from SUTE.

The Partial Tax Exemption scheme

Companies that do not qualify for SUTE, including those past their first three years, benefit from PTE. Under the partial-exemption scheme, 75% of the first S$10,000 of normal chargeable income is exempt and a further 50% of the next S$190,000 is exempt. This means the exemption applies to the first S$200,000 of chargeable income for every company.

The practical effect is that a company’s effective tax rate is well below 17% on its first S$200,000 of profits, tapering towards the headline rate as profits rise beyond that band.

The numbers in practice

Consider a qualifying start-up with S$200,000 of chargeable income. Under SUTE, S$75,000 (75% of the first S$100,000) plus S$50,000 (50% of the next S$100,000) is exempt, leaving S$75,000 taxable at 17%, or S$12,750. Without any exemption the tax would be S$34,000, so the saving is S$21,250 in that year. For a mature company on PTE, the first S$10,000 and half of the next S$190,000 are exempt, exempting S$102,500 of the S$200,000.

Filing timeline and obligations

Companies must file an Estimated Chargeable Income (ECI) within three months of their financial year end unless they qualify for the waiver, and file the annual corporate tax return (Form C-S, Form C-S (Lite) or Form C) by 30 November each year. The exemptions are applied in the assessment, so accurate ECI and return figures are essential. Records must be kept for at least five years under the Income Tax Act 1947.

Common mistakes and gotchas

The recurring pitfalls are assuming a holding or investment company qualifies for SUTE when it does not; breaching the shareholder conditions through a corporate shareholder holding all the shares; missing the tax residency requirement in a start-up year; and forgetting that SUTE runs only for the first three years of assessment, after which PTE applies. Clean shareholder records and timely ECI filing avoid most problems.
