What Is Income Tax on a 12 Lakh Salary?
Income tax on a Rs 12 lakh annual salary in FY 2025-26 is zero under the new tax regime and Rs 1,56,000 under the old regime without deductions.
Income tax in India is levied under the Income Tax Act 1961, administered by the Income Tax Department. For salaried employees, tax is computed on annual gross salary after subtracting the standard deduction and any eligible Chapter VI-A deductions, then applying the applicable slab rates.
The Finance Act 2025 expanded the new tax regime to cover zero tax for individuals with taxable income up to Rs 12,00,000 through the Section 87A rebate. For a Rs 12 lakh gross salary, the standard deduction of Rs 75,000 brings taxable income to Rs 11,25,000, well within the rebate threshold.
Income Tax Formula: How to Calculate Tax on 12 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 12 LPA | Notes |
|---|---|---|
| Gross salary | Rs 12,00,000 | Total annual CTC |
| Standard deduction | Rs 75,000 | Flat deduction under both regimes |
| Taxable income | Rs 11,25,000 | Gross minus standard deduction |
| Tax (new regime slabs) | Rs 52,500 | Before Section 87A rebate |
| Section 87A rebate | Rs 52,500 | Taxable income below Rs 12L ceiling |
| Net tax (new regime) | Rs 0 | After rebate; cess also zero |
| Net tax (old regime) | Rs 1,56,000 | No deductions; includes 4% cess |
The key variable for 12 LPA is the taxable income of Rs 11,25,000, which falls below the Section 87A ceiling of Rs 12,00,000. This single fact makes the entire new regime tax liability zero. The Rs 52,500 pre-rebate tax maps to the 5% slab on Rs 4-8L (Rs 20,000) and the 10% slab on Rs 8-11.25L (Rs 32,500).
Income Tax on 12 Lakh Salary in Excel: Three Methods
You can compute income tax on a Rs 12 lakh salary in Excel using a slab-by-slab formula. Place the taxable income (Rs 11,25,000) in cell A1. All three methods below return Rs 52,500 before the 87A rebate and Rs 0 after.
| Method | Formula | Result |
|---|---|---|
| Slab-by-slab | =MAX(0,(MIN(A1,800000)-400000)*0.05)+(MAX(0,MIN(A1,1200000)-800000)*0.1) | Rs 52,500 |
| 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 1,50,000 |
| Old regime + cess | =[old regime formula]*1.04 | Rs 1,56,000 |
The "With 87A rebate" row is the production formula for any income up to Rs 12,75,000 gross salary. The IF(A1<=1200000,0,...) check applies the rebate automatically. Above Rs 12,75,000 gross, replace the formula with the full new regime slab computation multiplied by 1.04 for cess.
New Regime Tax Breakdown: Why 12 LPA Pays Zero
Under the new tax regime in FY 2025-26, a Rs 12 lakh salary produces taxable income of Rs 11,25,000 after the standard deduction, which generates Rs 52,500 in tax before the Section 87A rebate eliminates it entirely.
| Income slab | Rate | Tax amount |
|---|---|---|
| Rs 0 to Rs 4,00,000 | 0% | Rs 0 |
| Rs 4,00,001 to Rs 8,00,000 | 5% | Rs 20,000 |
| Rs 8,00,001 to Rs 11,25,000 | 10% | Rs 32,500 |
| Total tax before rebate | Rs 52,500 | |
| Less: Section 87A rebate | - Rs 52,500 | |
| Net tax payable | Rs 0 | |
| Health and education cess (4%) | Rs 0 |
The Rs 8-11.25L band is taxed at 10%, generating Rs 32,500 on the Rs 3,25,000 income above the Rs 8L threshold. Combined with Rs 20,000 on the Rs 4-8L band, the pre-rebate total is Rs 52,500. The Finance Act 2025 set the Section 87A ceiling at Rs 12,00,000 net taxable income, so the full Rs 52,500 is wiped out.
Old Regime Tax Computation for 12 Lakh Salary
Under the old tax regime with no Chapter VI-A deductions beyond the standard deduction, income tax on Rs 12 lakh salary is Rs 1,50,000 before cess and Rs 1,56,000 including the 4% health and education cess.
| Income slab | Rate | Tax amount |
|---|---|---|
| Rs 0 to Rs 2,50,000 | 0% | Rs 0 |
| Rs 2,50,001 to Rs 5,00,000 | 5% | Rs 12,500 |
| Rs 5,00,001 to Rs 10,00,000 | 20% | Rs 1,00,000 |
| Rs 10,00,001 to Rs 11,25,000 | 30% | Rs 37,500 |
| Total tax before cess | Rs 1,50,000 | |
| Health and education cess (4%) | Rs 6,000 | |
| Total tax payable | Rs 1,56,000 |
The highest marginal rate under the old regime at Rs 12 lakh is 30%, applied to the Rs 1,25,000 of income above the Rs 10 lakh threshold, generating Rs 37,500 in tax from that band. The 4% cess on the base tax of Rs 1,50,000 adds Rs 6,000 to reach the final Rs 1,56,000. No Section 87A rebate applies under the old regime, where the ceiling is Rs 5,00,000 net taxable income.
Old vs New Regime: Which Is Better for 12 LPA?
The new regime is better for 12 LPA in every deduction scenario because the Rs 52,500 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 12,00,000 | Rs 12,00,000 |
| 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 11,25,000 | Rs 11,25,000 |
| Pre-rebate tax | Rs 52,500 | Rs 1,50,000 |
| Section 87A rebate | Rs 52,500 | Nil (threshold Rs 5L) |
| Net tax | Rs 0 | Rs 1,50,000 |
| 4% cess | Rs 0 | Rs 6,000 |
| Total annual tax | Rs 0 | Rs 1,56,000 |
| Monthly TDS | Rs 0 | Rs 13,000 |
| Monthly in-hand | Rs 93,800 | Rs 80,800 |
The monthly in-hand difference of Rs 13,000 (Rs 93,800 vs Rs 80,800) is a direct result of the zero TDS under the new regime. The old regime figure of Rs 80,800 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 Rs 60,000 Relief That Makes 12 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.
The rebate mechanism works by first computing the full tax liability at new regime slab rates, then reducing that liability by the lesser of the computed tax or Rs 60,000. For a Rs 12 lakh salary, computed tax is Rs 52,500. Since Rs 52,500 is less than the Rs 60,000 ceiling, the full amount is rebated and the final tax is zero.
The threshold is net taxable income, not gross salary. This means a gross salary of up to Rs 12,75,000 still qualifies for the full rebate, because the standard deduction of Rs 75,000 brings taxable income to exactly Rs 12,00,000. Above Rs 12,75,000 gross, the rebate no longer covers the entire tax liability.
Key facts about the Section 87A rebate
Income Tax on 12 Lakh Salary with Deductions
Even with maximum Chapter VI-A deductions including 80C at Rs 1,50,000, 80D at Rs 25,000, and NPS at Rs 75,000, the old regime tax on Rs 12 lakh salary is Rs 73,320, which is higher than the new regime's zero.
| Deductions claimed | Old regime tax | New regime tax | Verdict |
|---|---|---|---|
| None | Rs 1,56,000 | Rs 0 | New wins |
| 80C: Rs 1,50,000 | Rs 1,02,600 | Rs 0 | New wins |
| 80C + 80D: Rs 1,75,000 | Rs 93,600 | Rs 0 | New wins |
| 80C + 80D + NPS 80CCD: Rs 2,25,000 | Rs 73,320 | Rs 0 | New wins |
| 80C + 80D + NPS + HRA exempt: Rs 3,75,000 | Rs 31,200 | Rs 0 | New wins |
| 80C + 80D + NPS + HRA + Home loan: Rs 5,75,000 | Rs 2,080 | Rs 0 | New wins |
The new regime wins at every deduction level for Rs 12 lakh salary because of the Section 87A rebate. The breakeven scenario where the old regime might theoretically match would require combined deductions exceeding Rs 5,75,000, which is practically unachievable for most salaried employees. For most 12 LPA earners, the new regime saves between Rs 2,080 and Rs 1,56,000 in annual tax.
In-Hand Salary for 12 LPA: The Monthly Breakup
The monthly in-hand salary for Rs 12 lakh per annum is Rs 93,800 under the new tax regime, calculated after deducting Rs 6,000 in employee PF (12% of Rs 50,000 basic) and Rs 200 in professional tax, with zero income tax TDS.
| Component | Per month | Per year |
|---|---|---|
| Basic salary (50% of gross) | Rs 50,000 | Rs 6,00,000 |
| HRA (20% of gross) | Rs 20,000 | Rs 2,40,000 |
| Special allowance | Rs 30,000 | Rs 3,60,000 |
| Gross salary | Rs 1,00,000 | Rs 12,00,000 |
| Less: Employee PF (12% of basic) | - Rs 6,000 | - Rs 72,000 |
| Less: Professional tax | - Rs 200 | - Rs 2,400 |
| Less: Income tax TDS | Nil | Nil |
| Net in-hand salary | Rs 93,800 | Rs 11,25,600 |
The 50% basic assumption is standard across most Indian companies. At 40% basic, PF drops to Rs 4,800/month and in-hand rises to Rs 95,000. At 60% basic, PF rises to Rs 7,200/month and in-hand falls to Rs 92,600.
