Key Points
- Under the revised New Tax Regime (the default regime for FY 2025–26 / AY 2026–27), salaried employees pay zero income tax on taxable incomes up to ₹12 Lakhs thanks to the ₹75,000 standard deduction and Section 87A full tax rebate.
- For a ₹15 Lakh salary, the New Tax Regime saves approximately ₹42,900 in annual tax compared to the Old Regime unless you possess eligible deductions exceeding ₹4.25 Lakhs.
- At a ₹20 Lakh salary, the breakeven deduction required to make the Old Tax Regime beneficial rises to ₹6.75 Lakhs, making the New Regime superior for over 85% of corporate employees.
- The Old Tax Regime remains advantageous only for individuals with exceptionally high deductions—specifically those combining ₹2.0 Lakhs in home loan interest (Section 24b), ₹1.5 Lakhs in Section 80C, ₹50,000 in NPS (80CCD(1B)), and substantial HRA exemptions.
- Salaried employees have the flexibility to switch between the Old and New Tax Regimes every financial year when filing their Income Tax Return (ITR).

Every financial year, millions of working professionals across India face the same high-stakes payroll decision: Should I choose the New Tax Regime or stick with the Old Tax Regime?
With recent direct tax reforms significantly expanding the New Tax Regime—raising the standard deduction for salaried employees to ₹75,000, broadening slab bands, and extending the full Section 87A tax rebate up to a taxable income of ₹12 Lakhs—the calculus has shifted dramatically. The New Tax Regime is no longer just a simplified alternative; for the vast majority of Indian earners, it has become mathematically superior.
However, the Old Tax Regime is not obsolete. For homeowners servicing large residential mortgages, tenants paying high metropolitan rents, and families investing heavily in Section 80C, 80D, and NPS instruments, the Old Regime can still deliver tax savings. This comprehensive guide provides an exact slab-by-slab comparison, calculates the breakeven deduction thresholds across salary brackets, and helps you identify the optimal regime for your income.

Tax Regime Breakeven Calculator
The Breakeven Deduction Matrix Across Salary Brackets
The Breakeven Deduction Threshold is the exact total amount of exemptions and Chapter VI-A deductions you must claim under the Old Tax Regime for its tax bill to equal that of the New Tax Regime.
- If your total eligible deductions are GREATER than the Breakeven figure: The Old Tax Regime is better.
- If your total eligible deductions are LESS than the Breakeven figure: The New Tax Regime is better.
| Gross Annual Salary | New Regime Tax Payable | Breakeven Deductions Needed in Old Regime | Typical Regime Recommendation |
|---|---|---|---|
| ₹7,50,000 (7.5 LPA) | ₹0 (87A Rebate) | ₹2,00,000 | New Tax Regime (Zero Tax) |
| ₹10,00,000 (10 LPA) | ₹0 (87A Rebate) | ₹4,50,000 | New Tax Regime (Zero Tax) |
| ₹12,00,000 (12 LPA) | ₹0 (87A Rebate) | ₹6,50,000 | New Tax Regime (Zero Tax) |
| ₹15,00,000 (15 LPA) | ₹81,900 | ₹4,25,000 | New Tax Regime (for >90% earners) |
| ₹20,00,000 (20 LPA) | ₹1,64,445 | ₹6,75,000 | New Tax Regime |
| ₹25,00,000 (25 LPA) | ₹2,60,000 | ₹7,80,000 | New Tax Regime |
Key Takeaway: For salaries up to ₹12.75 Lakhs, the New Tax Regime is unconditionally superior, delivering a 100% tax-free income. At ₹15 Lakhs and above, the breakeven threshold sits so high (₹4.25L to ₹7.80L) that only individuals combining massive home loan interest and large HRA exemptions can justify opting for the Old Regime.
Two Practical Case Studies: Which Regime Wins?
Case Study A: Rahul (Age 28, Software Engineer, ₹15 LPA, Living in Rented Apartment)
- Gross Salary: ₹15,00,000
- Claimed Deductions (Old Regime): Section 80C (EPF + ELSS: ₹1,50,000), Section 80D (Health: ₹25,000), HRA Exemption (₹1,50,000). Total Deductions = ₹3,25,000.
- Old Regime Tax: ₹1,40,400
- New Regime Tax: ₹81,900
- Verdict: Rahul saves ₹58,500 in tax under the New Tax Regime, increasing his monthly in-hand take-home by ₹4,875.
Case Study B: Priya (Age 38, Director, ₹25 LPA, Servicing ₹60L Home Loan & Metro Rent)
- Gross Salary: ₹25,00,000
- Claimed Deductions (Old Regime): Section 24(b) Home Loan Interest (₹2,00,000), Section 80C (₹1,50,000), Section 80D (Self + Senior Parents: ₹75,000), Section 80CCD(1B) NPS (₹50,000), HRA Exemption (₹3,50,000). Total Deductions = ₹8,25,000.
- Old Regime Tax: ₹2,45,700
- New Regime Tax: ₹2,60,000
- Verdict: Because Priya's total deductions (₹8.25L) exceed the ₹7.80L breakeven point, Priya saves ₹14,300 under the Old Tax Regime.
Checklist for Making Your Annual Tax Regime Choice
- Assess Your Real Deductions: Add up your mandatory Section 80C investments, health insurance premiums, home loan interest certificates, and rent receipts.
- Compare Against the Breakeven Point: If your total claims fall short of the breakeven threshold for your salary bracket in the matrix above, choose the New Tax Regime.
- Consider Liquidity Freedom: The New Tax Regime allows you to invest surplus money in liquid open-ended mutual funds or emergency funds rather than locking capital into 3-year ELSS or 15-year PPF schemes purely to save tax.
- Switch at ITR Filing if Needed: Salaried individuals without business income can select one regime for monthly employer TDS declarations and switch to the other regime when filing their annual ITR if final investment proofs differ.
Frequently Asked Questions

No. The enhanced ₹75,000 standard deduction is exclusive to the New Tax Regime. Salaried employees opting for the Old Tax Regime receive the standard deduction of ₹50,000.
Do I have to submit investment proofs under the New Tax Regime?
No. The New Tax Regime does not require submitting proof for Section 80C, 80D, rent agreements, or home loan interest certificates, simplifying payroll compliance and eliminating year-end documentation stress.
Is Employer NPS deduction allowed under the New Tax Regime?
Yes. Contributions made by an employer toward the National Pension System (NPS) under Section 80CCD(2) are tax-exempt up to 14% of Basic Salary under both the New and Old Tax Regimes.
Why is the New Tax Regime called the "Default" regime?
