How this works

Singapore companies pay a flat 17% on chargeable income. Before the 17% is applied, IRAS exempts part of the income. Under the partial tax exemption (YA 2020 onwards), 75% of the first S$10,000 and 50% of the next S$190,000 is exempt, up to S$102,500. A qualifying new company can instead claim the start-up tax exemption for its first three Years of Assessment: 75% of the first S$100,000 and 50% of the next S$100,000, up to S$125,000.

For YA 2026 the Corporate Income Tax Rebate is 50% of tax payable, with total benefits capped at S$40,000. This was enhanced on 7 April 2026 from the 40% rebate, S$1,500 grant and S$30,000 cap announced at Budget 2026. Companies that paid CPF for at least one local employee (not a shareholder-director) in 2025 receive a S$2,000 cash grant, and their rebate is reduced by that S$2,000; if the rebate works out at S$2,000 or less, they get the grant only.

The effective rate shown is tax payable after the rebate divided by chargeable income. Chargeable income is profit after tax adjustments, capital allowances, donations and losses brought forward, so it is usually lower than accounting profit.
