Old vs. New Tax Regime: Which Should You Choose? (FY 2025-26)

Filing income tax returns in India comes with a major decision: the Old Tax Regime or the New Tax Regime? Since FY 2025-26, the New Regime is the default and has become significantly more attractive after the Budget 2025 changes — but the Old Regime can still win for taxpayers with large deductions. Here is the full slab-by-slab comparison and how to decide.

New Tax Regime Slabs (FY 2025-26)

The New Regime offers lower rates across the board but forgoes almost every deduction except the standard deduction. Budget 2025 raised the basic exemption limit to ₹4 lakh and widened the slabs:

Standard deduction: ₹75,000 for salaried individuals. Thanks to the Section 87A rebate (up to ₹60,000), taxable income up to ₹12 lakh is effectively tax-free under this regime — ₹12.75 lakh gross salary after the standard deduction.

Old Tax Regime Slabs (FY 2025-26)

The Old Regime keeps its long-standing, narrower slabs but lets you claim close to 70 deductions and exemptions on top of them:

Standard deduction: ₹50,000. The Section 87A rebate here tops out at ₹12,500, making income up to ₹5 lakh effectively tax-free — far lower than the New Regime's ₹12 lakh threshold. The trade-off is the deductions available on top:

• Section 80C: Up to ₹1.5 lakh for PPF, ELSS, EPF, life insurance premiums, and more.
• Section 80D: Health insurance premiums (₹25,000-₹1 lakh depending on age).
• HRA: House Rent Allowance exemption for salaried tenants.
• Home Loan Interest: Up to ₹2 lakh under Section 24(b) for a self-occupied property.
• NPS (80CCD): An additional ₹50,000 over and above the 80C limit.

Pros and Cons

New Regime

• Pro: Lower rates, ₹12 lakh effective tax-free threshold, simpler filing (no proof-of-investment paperwork).
• Pro: Better cash flow — no pressure to lock money into 80C-eligible instruments.
• Con: Forfeits HRA, home loan interest, 80C/80D, and most other deductions.

Old Regime

• Pro: Rewards disciplined savers — PPF, ELSS, insurance, and a home loan can add up to well over ₹3.5-4 lakh in deductions.
• Pro: HRA exemption alone can be substantial for tenants in metro cities.
• Con: Higher slab rates and a much lower ₹5 lakh tax-free threshold if you don't have enough deductions to offset it.

How to Make the Choice

Add up your realistic annual deductions: 80C investments, health insurance, HRA, home loan interest, and NPS. If that total is comfortably above ₹4 lakh, model both regimes before assuming the New Regime wins by default — it no longer always does, especially for higher earners with a home loan and full 80C utilization.

Conclusion

There is no permanent one-size-fits-all answer — and the rules change most years, as FY 2025-26 shows. Re-run the comparison at the start of every financial year, especially if your deductions, salary, or the slabs themselves have changed, and always confirm your final numbers before declaring your regime to your employer.
