How it works
Singapore taxes chargeable income at a flat 17%. The start-up exemption (first three years of assessment, for qualifying companies) exempts 75% of the first S$100,000 and 50% of the next S$100,000. The partial exemption (everyone else) exempts 75% of the first S$10,000 and 50% of the next S$190,000. Budget rebates, when announced, apply on top.
Worked example
Chargeable income of S$200,000. Start-up exemption: S$125,000 exempt, S$75,000 taxable, tax S$12,750. Partial exemption: S$102,500 exempt, S$97,500 taxable, tax S$16,575.
