The 4% rate applies to tax, not taxable income
For Tax Year 2026–27, Health & Education Cess is calculated at 4% on income tax plus surcharge where surcharge applies. It is not 4% of taxable income.
The ArthaSiddhi calculator stops at ₹50 lakh and does not model surcharge. In its supported examples, the cess base is therefore income tax after the applicable section 156 rebate or marginal relief.
Example: ₹13 lakh under the new regime
For ₹13,00,000 of taxable ordinary income, the engine calculates slab tax of ₹75,000. Marginal relief has ceased at this point, so tax after relief remains ₹75,000. Cess is 4% of ₹75,000, or ₹3,000—not 4% of ₹13,00,000.
| Slab tax | Rebate | Marginal relief | Tax after relief | 4% cess | Final estimate |
|---|---|---|---|---|---|
| ₹75,000 | ₹0 | ₹0 | ₹75,000 | ₹3,000 | ₹78,000 |
Why calculation order matters
Applying cess before rebate or marginal relief would overstate the supported result. The engine first calculates slabs, then relief, and only then cess.
