At ₹15 lakh gross salary with ₹1.5L (80C) + ₹25K (80D) + ₹50K (NPS) = ₹2.25L deductions under old regime: New regime tax = ₹97,500 (after ₹75K standard deduction). Old regime tax = ₹1,40,400 (after ₹50K standard deduction + ₹2.25L deductions). New regime saves ₹42,900. But if you also claim ₹2L HRA, old regime tax drops to ₹78,000 — beating new regime by ₹19,500. The break-even is around ₹3.75L in total deductions. Use our HRA Calculator to compute your exact HRA exemption.
The Indian income tax system offers two parallel regimes: the new regime (default, lower rates, fewer deductions) and the old regime (higher rates but allows Section 80C, 80D, HRA, NPS, and home loan deductions). This Income Tax Calculator India computes your tax under both regimes simultaneously and tells you which one saves more — based on your specific income and deduction profile.
The inflation perspective matters: as nominal salaries grow with inflation, more of your income falls into higher tax brackets (bracket creep), even if your real purchasing power hasn't increased. The Section 80C limit of ₹1.5 lakh, unchanged since 2014, and the old regime basic exemption of ₹2.5 lakh are being silently eroded by inflation every year. Explore this with our Inflation Calculator and Purchasing Power Calculator.
| Income Slab | New Regime Rate | Old Regime Rate (Below 60) |
|---|---|---|
| Up to ₹2.5 lakh | Nil (up to ₹4L) | Nil |
| ₹2.5L - ₹4L | Nil | 5% |
| ₹4L - ₹5L | 5% | 5% |
| ₹5L - ₹8L | 5% | 20% |
| ₹8L - ₹10L | 10% | 20% |
| ₹10L - ₹12L | 10% | 30% |
| ₹12L - ₹16L | 15% | 30% |
| ₹16L - ₹20L | 20% | 30% |
| ₹20L - ₹24L | 25% | 30% |
| Above ₹24L | 30% | 30% |
Standard deduction: ₹75,000 (new) / ₹50,000 (old). Section 87A rebate: ₹60,000 for taxable income up to ₹12L (new) / ₹12,500 for up to ₹5L (old). 4% Health and Education Cess on total tax. For detailed tax-saving strategies using Section 80C, 80D, NPS, and HRA, use our Tax Savings Calculator, HRA Calculator, and NPS Calculator.
| Gross Salary | New Regime Tax | Deductions Needed for Old Regime to Win | Common Deduction Sources |
|---|---|---|---|
| ₹8 lakh | ₹0 (rebate) | Old regime also ₹0 with ₹80C alone | 80C alone suffices |
| ₹10 lakh | ₹31,200 | >₹2.75 lakh | 80C (₹1.5L) + 80D (₹25K) + NPS (₹50K) + HRA (₹50K+) |
| ₹15 lakh | ₹97,500 | >₹3.75 lakh | 80C + 80D + NPS + HRA (₹1.5L+) or Home Loan Int |
| ₹20 lakh | ₹2,08,000 | >₹5.25 lakh | All of above + full ₹2L Home Loan + higher HRA |
| ₹25 lakh | ₹3,43,200 | >₹6.5 lakh | Needs HRA ₹3L+ and Home Loan ₹2L mandatory |
As income increases, the deduction threshold to beat new regime rises sharply. For most salaried individuals without HRA and home loan, the new regime wins above ₹10-12 lakh. The old regime wins only when you stack multiple large deductions — HRA being the most impactful for metro-based employees. Use our HRA Calculator to compute your exact exemption, EPF Calculator to see your 80C contribution from EPF, and EMI Calculator to plan home loan interest deductions.
Tax bracket creep is a silent wealth eroder that affects every salaried Indian. Here is how inflation pushes you into higher tax brackets:
| Year | Salary (8% growth) | New Regime Tax | Effective Rate | Real Salary (6% inflation adjusted) |
|---|---|---|---|---|
| 2025 | ₹12 lakh | ₹0 (rebate) | 0% | ₹12 lakh |
| 2028 | ₹15.1 lakh | ₹99,840 | 6.6% | ₹12.7 lakh |
| 2031 | ₹19.0 lakh | ₹1,87,200 | 9.8% | ₹13.4 lakh |
| 2035 | ₹25.9 lakh | ₹3,56,160 | 13.7% | ₹14.5 lakh |
Despite only a 21% increase in real purchasing power over 10 years, your effective tax rate jumps from 0% to 13.7%. This is bracket creep — you pay more tax not because you are richer, but because inflation pushed your nominal income past static tax thresholds. The government occasionally adjusts slabs (as in Budget 2025), but the adjustments rarely keep pace with cumulative inflation. Track this with our Inflation Calculator and plan proactively using our FIRE Calculator for long-term financial independence planning.
The new tax regime slabs for FY 2025-26 (AY 2026-27) are: up to ₹4 lakh — nil, ₹4-8 lakh — 5%, ₹8-12 lakh — 10%, ₹12-16 lakh — 15%, ₹16-20 lakh — 20%, ₹20-24 lakh — 25%, and above ₹24 lakh — 30%. A standard deduction of ₹75,000 is available for salaried individuals. Income up to ₹12 lakh (₹12.75 lakh for salaried after standard deduction) is effectively tax-free due to the Section 87A rebate of up to ₹60,000. Health and Education Cess of 4% applies on the total tax amount.
The old tax regime slabs for FY 2025-26 for individuals below 60 years are: up to ₹2.5 lakh — nil, ₹2.5-5 lakh — 5%, ₹5-10 lakh — 20%, and above ₹10 lakh — 30%. Senior citizens (60-80 years) get basic exemption up to ₹3 lakh, and super senior citizens (80+ years) get up to ₹5 lakh. The old regime allows multiple deductions: Section 80C (₹1.5 lakh), 80D (medical insurance), HRA exemption, home loan interest (₹2 lakh under Section 24), and a standard deduction of ₹50,000 for salaried individuals. Section 87A rebate of ₹12,500 applies for taxable income up to ₹5 lakh.
The new regime is better if your total deductions under the old regime are less than ₹3-4 lakh. The old regime is better if you claim significant deductions like HRA (₹2-4 lakh for metro dwellers), Section 80C (₹1.5 lakh), 80D (₹25,000-1 lakh), home loan interest (₹2 lakh), and NPS (₹50,000 extra under 80CCD). As a rule of thumb: at ₹10 lakh income, old regime wins if deductions exceed ₹2.75 lakh. At ₹15 lakh, old regime wins if deductions exceed ₹4 lakh. At ₹20 lakh, old regime wins if deductions exceed ₹5.5 lakh. This calculator compares both regimes side by side for your exact inputs.
Section 87A provides a tax rebate (direct reduction in tax payable) for resident individuals. Under the new regime for FY 2025-26, the rebate is up to ₹60,000 for taxable income up to ₹12 lakh, making income up to ₹12,75,000 (after ₹75,000 standard deduction) effectively tax-free. Under the old regime, the rebate is up to ₹12,500 for taxable income up to ₹5 lakh. Important: the rebate applies only to normal income tax, not to special rate income like LTCG or STCG. The rebate is available only to resident individuals, not to NRIs, HUFs, or companies.
Key deductions under the old regime include: Section 80C — up to ₹1.5 lakh (PPF, ELSS, EPF, life insurance, tuition fees, tax-saver FD, NPS Tier I, home loan principal). Section 80D — medical insurance premium (₹25,000 for self, ₹25,000 for parents, ₹50,000 if parents are senior citizens). Section 24(b) — home loan interest up to ₹2 lakh for self-occupied property. Section 80CCD(1B) — additional ₹50,000 for NPS contribution. Section 80E — education loan interest (no limit). HRA exemption under Section 10(13A). LTA exemption. Standard deduction of ₹50,000 for salaried employees. These deductions can reduce taxable income by ₹4-8 lakh for well-planned taxpayers.
Inflation impacts tax planning in three ways. First, the tax slabs are not automatically inflation-indexed — the ₹2.5 lakh basic exemption under the old regime has remained unchanged for years, meaning more income falls into taxable brackets as nominal salaries grow with inflation. Second, the Section 80C limit of ₹1.5 lakh was set in 2014 — its real value has eroded by over 60% due to inflation, yet the limit remains unchanged. Third, your salary growth due to inflation pushes you into higher tax brackets (bracket creep) even though your real purchasing power may not have increased. Use our Inflation Calculator to see how bracket creep silently increases your effective tax rate over the years.
The standard deduction for FY 2025-26 is ₹75,000 under the new tax regime and ₹50,000 under the old tax regime, available to salaried employees and pensioners. This is a flat deduction from salary income — no proof or investment required. Under the new regime, the ₹75,000 standard deduction effectively raises the tax-free threshold to ₹12,75,000 (₹12 lakh rebate limit + ₹75,000 standard deduction). The standard deduction replaced the earlier transport allowance (₹19,200) and medical reimbursement (₹15,000) from FY 2018-19.
Income tax calculation follows these steps: Step 1 — Calculate Gross Total Income (salary + house property + business income + capital gains + other sources). Step 2 — Deduct standard deduction (₹75,000 new regime or ₹50,000 old regime) and other exemptions (HRA, LTA in old regime). Step 3 — Deduct Chapter VIA deductions (80C, 80D, 80E, 80CCD in old regime only). Step 4 — Apply tax slab rates on the resulting taxable income. Step 5 — Apply Section 87A rebate if eligible. Step 6 — Add 4% Health and Education Cess. Step 7 — Deduct TDS already paid to get net tax payable or refund. This calculator automates all these steps for both regimes.
