Corporate tax exemptions and partial-exemption scheme — Eligibility and requirements checklist

Corporate tax exemptions and partial-exemption scheme rules reduce the effective tax a Singapore company pays on its first tranches of chargeable income. The start-up exemption shelters qualifying new companies, while the partial-exemption scheme applies to almost every company, lowering the effective rate well below the 17% headline figure in early profit ranges.

How corporate tax exemptions and partial-exemption scheme relief work

Singapore charges corporate income tax at a flat headline rate of 17% under the Income Tax Act 1947, but two exemption schemes carve out a slice of chargeable income before that rate applies. The Start-Up Tax Exemption rewards qualifying new companies in their first three years of assessment, and the Partial Tax Exemption applies to all other companies and to start-ups from their fourth year. Both work the same way mechanically — a percentage of income within defined bands is exempt — so the effective rate on early profits is materially lower than 17%.

Start-up tax exemption: who qualifies

The Start-Up Tax Exemption exempts 75% of the first S$100,000 of normal chargeable income and a further 50% of the next S$100,000, for each of the company’s first three consecutive years of assessment. To qualify, the company must be incorporated in Singapore, be a tax resident here for that year, and have no more than 20 shareholders throughout the basis period — all individuals, or with at least one individual holding at least 10% of the ordinary shares. Property and investment holding companies are excluded, which is a deliberate targeting of genuine operating start-ups.

Partial-exemption scheme: who qualifies

The Partial Tax Exemption applies to every company that is not claiming the start-up exemption, with no shareholder or activity restrictions. It exempts 75% of the first S$10,000 of normal chargeable income and 50% of the next S$190,000. That shelters up to S$102,500 of income from tax within the first S$200,000, giving a meaningful reduction for small and medium companies without any application process — it is applied automatically in the tax computation.

Eligibility and requirements checklist

  • Start-up exemption: Singapore-incorporated, tax-resident, first three years of assessment, 20 or fewer shareholders with the individual-shareholding condition met.
  • Start-up exemption exclusions: investment holding and property-development companies.
  • Partial exemption: available to all other companies automatically.
  • Timely filing of the Estimated Chargeable Income and the Form C-S or Form C.
  • Proper accounts and a tax computation applying the exemption bands.

The exemptions interact with reliefs elsewhere in the group; where losses or profits move between related companies, read this alongside group relief for Singapore companies. For the compliance calendar and processing times, see our Singapore corporate tax rates, exemptions and filing guide.

Worked effective-rate example

Consider a qualifying start-up with S$200,000 of chargeable income in its first year. The first S$100,000 is 75% exempt, leaving S$25,000 taxable; the next S$100,000 is 50% exempt, leaving S$50,000 taxable. Total taxable income is S$75,000, taxed at 17% for S$12,750 — an effective rate of about 6.4% rather than the 17% headline. A mature company on the partial-exemption scheme with the same income shelters S$102,500, taxing S$97,500 at 17% for S$16,575, an effective rate near 8.3%.

Common mistakes and gotchas

The classic error is assuming a holding company qualifies for the start-up exemption — investment holding companies are specifically excluded and only get partial exemption. Another is losing the exemption by exceeding 20 shareholders or failing the individual-shareholding test after a funding round. Companies also forget that the exemption applies to normal chargeable income and not to income taxed at concessionary rates, and that exempt amounts still count when computing certain thresholds. Filing the Estimated Chargeable Income late can also forfeit instalment benefits.

Numerical specifics at a glance

Headline rate 17%; start-up exemption 75% of first S$100,000 plus 50% of next S$100,000 for first three years of assessment; partial exemption 75% of first S$10,000 plus 50% of next S$190,000; shareholder cap for start-up exemption 20; effective early-year rate around 6% to 8%; Form C-S or Form C filing due 30 November each year.

Interaction with tax residency and concessionary rates

The exemptions apply only to normal chargeable income taxed at the 17% headline rate, and only where the company is a Singapore tax resident for the year. Income taxed at a concessionary rate under an incentive, and income already exempt under another provision, does not get a second bite. A company must also be genuinely resident — that is, controlled and managed in Singapore — which turns on where board decisions are actually made. Groups that run board meetings offshore can inadvertently lose residency and, with it, access to the start-up exemption.

Losses, capital allowances and the exemption stack

Exemptions sit at the end of the computation, after trading income has been reduced by capital allowances, approved donations and brought-forward or current-year losses. This ordering matters: a company with large capital allowances may have little chargeable income left for the exemption to shelter, so the headline benefit is smaller than the percentages suggest. Where a group has profitable and loss-making companies, loss transfer under the group relief system can be more valuable than the exemption itself, which is why the two are planned together.

Filing mechanics: ECI, Form C-S and Form C

Every company must file an Estimated Chargeable Income within three months of its financial year end, unless it qualifies for the filing waiver, and then file the Form C-S, Form C-S (Lite) or Form C by 30 November. Small companies with straightforward affairs and revenue under the prescribed cap use the simplified Form C-S; the Lite version is for the smallest. Filing the ECI on time preserves the option to pay tax by instalments, an easily overlooked cash-flow benefit that sits alongside the exemptions.
