Singapore — Tax: Corporate Tax
Singapore's corporate tax rate is a flat 17% on chargeable income, applying equally to local and foreign companies — one of the most competitive headline rates in ASEAN. For Year of Assessment 2026, a Corporate Income Tax rebate of 40% of tax payable (capped at SGD 30,000) is granted to all active taxpaying companies, materially lowering the effective rate for smaller/mid-size businesses. Various partial tax exemption schemes for new startups and smaller companies can further reduce the effective rate on the first tranches of chargeable income.
