Singapore Corporate Income Tax Calculator
This corporate income tax calculator helps Singapore companies estimate tax payable using normal chargeable income taxed at the prevailing 17% corporate income tax rate. It applies the YA 2020-onward partial tax exemption and start-up tax exemption formulas, and can estimate the effect of YA 2024, YA 2025 or YA 2026 CIT rebate settings.
The most important input is chargeable income. This is not necessarily the same as accounting profit. Chargeable income is after tax adjustments such as non-deductible expenses, capital allowances, unutilised losses, donations and other tax rules. Use your tax computation or ECI estimate as the starting point.

How this calculator treats YA 2026 rebate and cash grant
For YA 2026, IRAS states that the CIT rebate is 50% of corporate tax payable, capped at $40,000. Where the company is eligible for the $2,000 CIT Rebate Cash Grant, the CIT rebate is reduced by that cash grant amount where applicable. This calculator therefore shows the allowed CIT rebate and the cash grant benefit separately.
Corporate Income Tax Calculator FAQ
What does this corporate income tax calculator estimate?
It estimates Singapore corporate income tax using chargeable income, the 17% corporate tax rate, partial tax exemption or start-up tax exemption, tax set-offs and the selected YA rebate settings.
Should I enter accounting profit or chargeable income?
Enter chargeable income after tax adjustments, deductions, capital allowances, loss set-offs and other adjustments. Accounting profit is not always the same as chargeable income.
Can this calculator confirm start-up tax exemption eligibility?
No. It can apply the start-up exemption formula, but you must confirm that the company is incorporated in Singapore, tax resident for the YA, within its first 3 consecutive YAs and satisfies IRAS shareholding and exclusion rules.
Does this replace IRAS tax assessment?
No. This is an educational estimate. IRAS computes the final corporate income tax, exemptions, rebates and cash grant treatment based on the ECI or Form C-S/Form C-S (Lite)/Form C filed.
