Choosing between the New Tax Regime (Section 115BAC) and the Old Tax Regime remains one of the most consequential financial decisions for Indian taxpayers. With recent amendments enhancing the New Regime—such as the ₹75,000 standard deduction and the Budget 2025 rebate that makes taxable income up to ₹12,00,000 tax-free (₹12,75,000 for salaried individuals)—the New Regime has become the default statutory option.
However, does the New Regime genuinely beat the Old Regime if you have high HRA, home loan interest, NPS, and health insurance?
In this guide, we break down the exact slab structures, mathematical breakeven points, and provide an actionable roadmap for every income bracket.

New Tax Regime (Default under Section 115BAC)
| Income Slab | Tax Rate | Notes |
|---|---|---|
| Up to ₹4,00,000 | NIL | Basic exemption |
| ₹4,00,001 to ₹8,00,000 | 5% | Fully covered by the 87A rebate if taxable income is up to ₹12 Lakhs |
| ₹8,00,001 to ₹12,00,000 | 10% | Effective zero tax for salaried up to ₹12.75 Lakhs |
| ₹12,00,001 to ₹16,00,000 | 15% | Marginal relief applies just above ₹12 Lakhs |
| ₹16,00,001 to ₹20,00,000 | 20% | Compared to 30% in Old Regime |

Key New Regime Perks:
- Standard Deduction: ₹75,000 for salaried employees and pensioners.
- Section 87A Rebate: Up to ₹60,000 (taxable income up to ₹12,00,000). For salaried individuals, ₹12,00,000 + ₹75,000 standard deduction means zero tax up to ₹12,75,000. The rebate does not cover income taxed at special rates, such as capital gains.
- Family Pension Deduction: Enhanced up to ₹25,000.
- Employer’s NPS Contribution: Allowed under Section 80CCD(2) up to 14% of salary for government/private employees.
Old Tax Regime (Optional)
| Income Slab | Tax Rate | Notes |
|---|---|---|
| Up to ₹2,50,000 | NIL | Basic exemption (₹3L for Senior Citizens, ₹5L for Super Senior) |
| ₹2,50,001 to ₹5,00,000 | 5% | Section 87A rebate up to ₹12,500 (Net zero tax up to ₹5 Lakhs) |
| ₹5,00,001 to ₹10,00,000 | 20% | Steep 15% jump from the previous slab |
| Above ₹10,00,000 | 30% | Maximum marginal rate applies early |
The Breakeven Deduction Formula: When Does Old Regime Win?
To decide whether to opt for the Old Regime, you must calculate your Total Eligible Deductions:
- Section 80C (EPF, PPF, ELSS, Life Insurance, Tuition Fees): Max ₹1,50,000
- Section 80D (Health Insurance for self, family, parents): Up to ₹25,000 to ₹1,00,000
- Section 24(b) (Home Loan Interest for self-occupied property): Max ₹2,00,000
- Section 10(13A) (HRA Exemption): Actual rent paid minus 10% of salary
- Section 80CCD(1B) (Additional Self NPS): Max ₹50,000
Breakeven Deduction Thresholds:
| Gross Annual Salary | Breakeven Deductions Required to Beat New Regime |
|---|---|
| Up to ₹12,75,000 | New Regime tax is already zero; the Old Regime can only match it |
| ₹15,00,000 | Must exceed ₹5,44,000 |
| ₹18,00,000 | Must exceed ₹6,42,000 |
| ₹20,00,000 | Must exceed ₹7,08,500 |
| ₹24,00,000+ | Must exceed ₹8,00,000 |
Deductions here exclude the standard deduction (₹50,000 Old, ₹75,000 New), which is already factored in.
Rule of Thumb: After Budget 2025, the Old Regime wins only with very large deductions. If your total deductions (HRA + 80C + 80D + Home Loan Interest + NPS) are below ₹5,00,000, the New Tax Regime is almost always more profitable, saving both tax cash and tedious paperwork.
Case Study: Salaried Professional Earning ₹15,00,000
Let us compute the exact tax liability for Ananya earning ₹15,00,000 gross salary:
- HRA Exemption: ₹1,80,000
- 80C Deductions: ₹1,50,000
- 80D Health Insurance: ₹25,000
- Standard Deduction: ₹50,000 (Old) vs ₹75,000 (New)
Calculation:
| Parameter | Old Tax Regime | New Tax Regime |
|---|---|---|
| Gross Salary | ₹15,00,000 | ₹15,00,000 |
| Standard Deduction | - ₹50,000 | - ₹75,000 |
| HRA Exemption | - ₹1,80,000 | NIL |
| Section 80C | - ₹1,50,000 | NIL |
| Section 80D | - ₹25,000 | NIL |
| Net Taxable Income | ₹10,95,000 | ₹14,25,000 |
| Base Tax | ₹1,41,000 | ₹93,750 |
| 4% Health & Edu Cess | ₹5,640 | ₹3,750 |
| Total Tax Payable | ₹1,46,640 | ₹97,500 |
| Verdict | Pays ₹49,140 more | Saves ₹49,140! |
Even with ₹3,55,000 worth of deductions, the New Tax Regime still saves Ananya ₹49,140 because of the wider, lower slabs introduced by Budget 2025 (5% on ₹4–8 Lakhs, 10% on ₹8–12 Lakhs and 15% on ₹12–16 Lakhs).
How and When to Switch Regimes
- Salaried Employees (No Business Income): Can choose their preferred regime every single year at the time of filing their annual ITR (ITR-1 or ITR-2) on or before the statutory due date (July 31st).
- Business Owners & Freelancers (Having Business/Professional Income): If a person with business income opts for the Old Regime, they must file Form 10-IEA before the ITR due date. Furthermore, they are allowed to switch back to the New Regime only once in a lifetime. Once they switch back to the New Regime, they cannot re-enter the Old Regime unless their business income ceases to exist.
Frequently Asked Questions (FAQs)
Is Form 10-IEA required for salaried employees?
No. Form 10-IEA is strictly required only for individuals having income under “Profits and Gains of Business or Profession” (PGBP). Salaried employees can toggle between Old and New regimes directly within the ITR utility without filing Form 10-IEA.
Can I choose one regime with my employer and another while filing ITR?
Yes. If your employer deducted TDS based on the New Regime (or Old Regime), you can still choose the alternate regime when filing your return under Section 139(1) and claim any excess TDS as a refund.
