For ₹15 lakh taxable income under the new tax regime in FY 2025-26, the income tax before cess is ₹1,05,000, and the total after 4% Health and Education Cess is ₹1,09,200. This assumes ₹15 lakh is already taxable income, not gross salary.
For a salaried taxpayer earning ₹15 lakh gross salary, the ₹75,000 standard deduction reduces taxable income to ₹14.25 lakh, resulting in tax of ₹97,500 including cess.
This article compares these figures with ₹12 lakh, ₹13 lakh, ₹14 lakh, ₹16 lakh and ₹20 lakh income under the FY 2025-26 new regime and explains how Section 87A and marginal relief affect the calculation.
Tax on 15 Lakh Income in New Regime
The FY 2025-26 new regime uses progressive slabs: nil up to ₹4 lakh, 5% from ₹4–8 lakh, 10% from ₹8–12 lakh, 15% from ₹12–16 lakh, 20% from ₹16–20 lakh, 25% from ₹20–24 lakh, and 30% above ₹24 lakh.
For ₹15 lakh taxable income, the calculation is:
| Income Slab | Tax Rate | Tax |
|---|---|---|
| Up to ₹4,00,000 | Nil | ₹0 |
| ₹4,00,000 to ₹8,00,000 | 5% | ₹20,000 |
| ₹8,00,000 to ₹12,00,000 | 10% | ₹40,000 |
| ₹12,00,000 to ₹15,00,000 | 15% | ₹45,000 |
| Total income tax | ₹1,05,000 | |
| Health and Education Cess | 4% | ₹4,200 |
| Final tax payable | ₹1,09,200 |
Section 87A does not reduce this liability because taxable income exceeds the ₹12 lakh eligibility threshold. The 15% rate applies only to the ₹12–15 lakh portion, not the entire ₹15 lakh.

12 Lakh Tax Slab New Regime
The ₹12 lakh threshold matters because eligible resident individuals can claim a Section 87A rebate of up to ₹60,000 when taxable income does not exceed ₹12 lakh.
At exactly ₹12 lakh taxable income, the slab tax is ₹20,000 (5% band) plus ₹40,000 (10% band) = ₹60,000. The rebate can offset this, resulting in nil income tax before any separately taxed special-rate income.
What happens to a ₹12.75 lakh salary?
For an eligible salaried taxpayer, the ₹75,000 standard deduction means ₹12.75 lakh gross salary can produce ₹12 lakh taxable income, assuming no other taxable income.
This does not make ₹12.75 lakh a universal zero-tax figure for every income type.
Tax on 20 Lakh Income New Regime
For ₹20 lakh taxable income, the 20% slab applies after ₹16 lakh:
| Income Slab | Tax Rate | Tax |
|---|---|---|
| Up to ₹4,00,000 | Nil | ₹0 |
| ₹4,00,000 to ₹8,00,000 | 5% | ₹20,000 |
| ₹8,00,000 to ₹12,00,000 | 10% | ₹40,000 |
| ₹12,00,000 to ₹16,00,000 | 15% | ₹60,000 |
| ₹16,00,000 to ₹20,00,000 | 20% | ₹80,000 |
| Total income tax | ₹2,00,000 | |
| Health and Education Cess | 4% | ₹8,000 |
| Final tax payable | ₹2,08,000 |
The effective rate is about 10.4% of ₹20 lakh because the 20% rate applies only to the ₹16–20 lakh band.
Tax on 13 Lakh, 14 Lakh and 16 Lakh Income
| Taxable Income | Tax Before Cess | 4% Cess | Final Tax |
|---|---|---|---|
| ₹12 lakh | ₹60,000* | ₹2,400* | Nil* |
| ₹13 lakh | ₹75,000 | ₹3,000 | ₹78,000 |
| ₹14 lakh | ₹90,000 | ₹3,600 | ₹93,600 |
| ₹15 lakh | ₹1,05,000 | ₹4,200 | ₹1,09,200 |
| ₹16 lakh | ₹1,20,000 | ₹4,800 | ₹1,24,800 |
| ₹20 lakh | ₹2,00,000 | ₹8,000 | ₹2,08,000 |
*At ₹12 lakh taxable income, the eligible Section 87A rebate can offset the ₹60,000 slab tax, resulting in nil tax.
For ₹13 lakh taxable income, the first ₹12 lakh generates ₹60,000, and the extra ₹1 lakh at 15% adds ₹15,000, giving ₹78,000 after cess.
For ₹14 lakh, another ₹1 lakh at 15% gives ₹93,600 after cess. At ₹16 lakh, the full ₹12–16 lakh band is taxed at 15%, producing ₹1,24,800 after cess.
How Section 87A Rebate and Marginal Relief Affect the Calculation
Section 87A is a rebate for eligible resident individuals. Under the FY 2025-26 new regime, it can be up to ₹60,000 when taxable income does not exceed ₹12 lakh.
It is not a partial benefit for everyone earning slightly more.
Marginal relief addresses the sharp increase just above ₹12 lakh. It is meant for taxpayers only slightly above the threshold, not for incomes well beyond it such as ₹15 lakh.
Calculations near the ₹12–13 lakh range should account for both provisions.
₹15 Lakh Salary vs ₹15 Lakh Taxable Income
A ₹15 lakh salary and ₹15 lakh taxable income are different starting points.
For an eligible salaried taxpayer:
₹15,00,000 gross salary − ₹75,000 standard deduction = ₹14,25,000 taxable income
Tax on ₹14.25 lakh: ₹0 + ₹20,000 + ₹40,000 + (₹2.25 lakh × 15%) = ₹93,750 before cess, and ₹97,500 after 4% cess.
If other taxable income brings total taxable income back to ₹15 lakh, the liability returns to ₹1,09,200. The starting point determines the calculation.

Common Mistakes When Calculating Tax on ₹15 Lakh
Treating CTC as taxable income. CTC includes employer PF, gratuity and other components that are not immediately taxable.
Applying 15% to the entire ₹15 lakh. The 15% rate applies only to income between ₹12 lakh and ₹16 lakh.
Forgetting the standard deduction. Eligible salaried taxpayers can reduce gross salary by ₹75,000 before applying slab rates.
Ignoring the ₹12 lakh rebate threshold. Section 87A and marginal relief must be checked for income near ₹12 lakh.
Forgetting cess. Health and Education Cess is 4% of income tax plus applicable surcharge.
Confusing FY and AY. FY 2025-26 income is reported for AY 2026-27.
Practical Takeaway
If ₹15 lakh is taxable income, the tax is ₹1,05,000 before cess and ₹1,09,200 after cess.
If ₹15 lakh is gross salary, an eligible salaried taxpayer applies the ₹75,000 standard deduction, giving ₹14.25 lakh taxable income and about ₹97,500 tax including cess.
For comparison, ₹12 lakh taxable income can qualify for the Section 87A rebate, while ₹20 lakh taxable income results in ₹2,08,000 including cess.
