What Is Income Tax on a 8 Lakh Salary?
Income tax on a Rs 8 lakh annual salary in FY 2025-26 is zero under the new tax regime and Rs 65,000 under the old regime without deductions.
The new tax regime introduced by the Finance Act 2025 is the clear choice for a Rs 8 lakh salary: zero TDS deduction, Rs 62,467 monthly in-hand, and no paperwork for exemptions or declarations. The old regime produces Rs 65,000 in tax on the same gross with no deductions, a gap of Rs 65,000 per year that no Section 80C or 80D claim can recover.
The Finance Act 2025 expanded the new tax regime to deliver zero tax for individuals with taxable income up to Rs 12,00,000 through the Section 87A rebate. For a Rs 8 lakh gross salary, the standard deduction of Rs 75,000 brings taxable income to Rs 7,25,000, well within the rebate threshold.
Income Tax Formula: How to Calculate Tax on 8 LPA
Income tax on salary is computed in four steps: gross salary minus standard deduction gives net salary, apply the applicable slab rates, check for Section 87A rebate eligibility, then add the 4% cess on any remaining tax liability.
Tax = (Slab rates on taxable income) - 87A rebate, then add 4% cess| Variable | Value for 8 LPA | Notes |
|---|---|---|
| Gross salary | Rs 8,00,000 | Total annual CTC |
| Standard deduction | Rs 75,000 | Flat deduction under both regimes |
| Taxable income | Rs 7,25,000 | Gross minus standard deduction |
| Tax (new regime slabs) | Rs 16,250 | Before Section 87A rebate |
| Section 87A rebate | Rs 16,250 | Taxable income below Rs 12L ceiling |
| Net tax (new regime) | Rs 0 | After rebate; cess also zero |
| Net tax (old regime) | Rs 65,000 | No deductions; includes 4% cess |
Income Tax on 8 Lakh Salary in Excel: Three Methods
You can compute income tax on a Rs 8 lakh salary in Excel using a slab-by-slab formula. Place the taxable income (Rs 7,25,000) in cell A1.

| With 87A rebate | =IF(A1<=1200000,0,[above formula]*1.04) | Rs 0 (tax-free) |
| Old regime | =MAX(0,(MIN(A1,500000)-250000)*0.05)+(MAX(0,MIN(A1,1000000)-500000)*0.2)+(MAX(0,A1-1000000)*0.3) | Rs 62,500 |
| Old regime + cess | =[old regime formula]*1.04 | Rs 65,000 |
New Regime Tax Breakdown: Why 8 LPA Pays Zero
Under the new tax regime in FY 2025-26, a Rs 8 lakh salary produces taxable income of Rs 7,25,000 after the standard deduction, which generates Rs 16,250 in tax before the Section 87A rebate eliminates it entirely.

| Rs 4,00,001 to Rs 7,25,000 | 5% | Rs 16,250 |

Old Regime Tax Computation for 8 Lakh Salary

Old vs New Regime: Which Is Better for 8 LPA?
The new regime is better for 8 LPA in every deduction scenario because the Rs Rs 16,250 tax liability is wiped out by Section 87A, while the old regime never reaches zero tax regardless of deductions at this income level.
| Metric | New regime | Old regime |
|---|---|---|
| Gross salary | Rs 8,00,000 | Rs 8,00,000 |
| Standard deduction | Rs 75,000 | Rs 75,000 |
| 80C deductions | Not allowed | Up to Rs 1,50,000 |
| 80D deductions | Not allowed | Up to Rs 25,000 |
| Taxable income | Rs 7,25,000 | Rs 7,25,000 |
| Pre-rebate tax | Rs 16,250 | Rs 62,500 |
| Section 87A rebate | Rs 16,250 | Nil (threshold Rs 5L) |
| Net tax | Rs 0 | Rs 62,500 |
| 4% cess | Rs 0 | Rs 2,500 |
| Total annual tax | Rs 0 | Rs 65,000 |
| Monthly TDS | Rs 0 | Rs 5,417 |
| Monthly in-hand | Rs 62,467 | Rs 57,050 |
The monthly in-hand difference of Rs 5,417 (Rs 62,467 vs Rs 57,050) is a direct result of the zero TDS under the new regime. The old regime figure assumes no Chapter VI-A deductions. Claiming 80C and 80D reduces old regime TDS, narrowing the gap but never eliminating it.
Section 87A Rebate: The Relief That Makes 8 LPA Tax-Free
Section 87A of the Income Tax Act 1961 provides a tax rebate of up to Rs 60,000 for resident individuals whose net taxable income does not exceed Rs 12,00,000 under the new regime in FY 2025-26. For Rs 8 lakh salary, taxable income is Rs 7,25,000, which is below the ceiling, so the full Rs 16,250 tax is rebated.
