Old vs New Tax Regime: Which One Saves You More in FY 2025-26?

Meera, 32, a marketing manager in Bengaluru earning Rs 14 lakh a year, spent two hours on the Income Tax e-filing portal last March, unsure whether to stick with the Old Tax Regime or switch to the New one.

She is not alone. Every year, millions of salaried Indians face the same dilemma - and with the Union Budget 2025 significantly revamping the New Tax Regime, the stakes are higher than ever.

The right choice could mean saving anywhere between Rs 25,000 and Rs 1.5 lakh annually, depending on your income and investment profile. This guide breaks down every key difference, with real numbers, so you can decide with confidence.

Budget 2025 Key Update: Under the New Tax Regime, the Section 87A rebate has been raised to Rs 60,000, making income up to Rs 12 lakh effectively tax-free. The Standard Deduction has also been increased to Rs 75,000 - up from Rs 50,000. These changes make FY 2025-26 a critical year to reassess your tax choice.

What Changed in FY 2025-26 (AY 2026-27)?

The Finance Act 2025 made the New Tax Regime more attractive for middle-income earners through three structural changes:

• Higher rebate: Section 87A rebate increased from Rs 25,000 to Rs 60,000, eliminating tax for net taxable income up to Rs 12 lakh.
• Wider Standard Deduction: Salaried individuals can now deduct Rs 75,000 (up from Rs 50,000), making a gross salary of up to Rs 12.75 lakh completely tax-free.
• Default regime status: The New Regime remains the default. If you do not actively opt out, you are automatically taxed under it.

Income Tax Slabs: Old vs New Regime for FY 2025-26

Here is how your income is taxed under each regime for Assessment Year 2026-27:

*Basic exemption for Senior Citizens (60-80 years): Rs 3 lakh. Super Senior Citizens (above 80 years): Rs 5 lakh - Old Regime only.

Note: A 4% Health and Education Cess applies on the final tax amount under both regimes. A surcharge applies for income above Rs 50 lakh.

Deductions and Exemptions: What You Keep, What You Lose

This is where the real decision gets made. The Old Regime lets you reduce taxable income through a wide range of deductions. The New Regime eliminates most of them in exchange for lower slab rates.

Key Insight: The employer's NPS contribution under Section 80CCD(2) is one of the few deductions available under the New Regime. If your employer offers NPS, ensure you are enrolled - this can save up to Rs 1.08 lakh in tax for higher earners.

The Breakeven Analysis: When Does the Old Regime Win?

The breakeven point is the total value of deductions at which both regimes produce the same tax outgo. If your deductions exceed this threshold, the Old Regime saves more money.

Meera's Calculation (Gross Income: Rs 14 lakh)

Under the New Regime: Gross income Rs 14 lakh − Standard Deduction Rs 75,000 = Net Taxable Income Rs 13.25 lakh. Tax calculated at new slab rates ≈ Rs 1,22,500 + 4% cess = Rs 1,27,400.

Under the Old Regime: Gross income Rs 14 lakh − Section 80C Rs 1.5 lakh − Home Loan interest Rs 1.2 lakh − Section 80D Rs 25,000 − Standard Deduction Rs 50,000 = Net Taxable Income Rs 10.55 lakh. Tax ≈ Rs 1,27,500 + 4% cess = Rs 1,32,600.

Verdict: With Rs 2.95 lakh in deductions - below the Rs 3.25 lakh breakeven - Meera saves approximately Rs 5,200 more under the New Regime.

Who Benefits Most from the New Tax Regime?

The New Regime is particularly advantageous for the following profiles:

• Young professionals and first-time earners with income up to Rs 12.75 lakh and minimal long-term investments - zero tax liability with standard deduction.
• Individuals earning up to Rs 12 lakh with limited deductions (no home loan, no HRA claim, minimal 80C investments) - the Rs 60,000 rebate eliminates tax entirely.
• Self-employed professionals who find it burdensome to maintain investment proofs and prefer a simplified filing process.
• Taxpayers with employer NPS contributions can benefit from the Section 80CCD(2) deduction even under the New Regime.

Who Should Stick with the Old Tax Regime?

Despite the Budget 2025 improvements to the New Regime, the Old Regime remains superior for certain taxpayer profiles:

• Home loan holders with significant interest outgo: If you pay Rs 2 lakh+ annually in home loan interest alone, the Section 24(b) deduction offers a substantial tax shield not available in the New Regime.
• High-HRA earners in metro cities: Employees paying substantial rent in cities like Mumbai, Delhi, or Bengaluru can claim tax-free HRA, often amounting to Rs 1.5–2.5 lakh annually.
• Disciplined investors with maxed-out 80C: If you invest Rs 1.5 lakh in ELSS, PPF, or insurance premiums and have additional 80D and NPS deductions, total deductions can exceed Rs 4.25 lakh - tipping the balance.
• Senior citizens and retirees: The Old Regime offers a higher basic exemption limit of Rs 3 lakh (Senior Citizens) and Rs 5 lakh (Super Senior Citizens), and the Section 80TTB deduction of Rs 50,000 on interest income - not available under the New Regime.

How to Switch Between Tax Regimes

Switching is straightforward for most taxpayers, but the rules differ based on income source:

Important: If your employer is not notified of your regime choice before TDS deduction (usually April), excess TDS may be deducted. Salaried employees should submit their declaration to the HR/payroll team at the start of each financial year.

Old vs New Tax Regime: At-a-Glance Comparison

Conclusion

For most taxpayers earning up to Rs 12.75 lakh with limited deductions, the New Tax Regime in FY 2025-26 is the clear winner - zero tax liability, simplified filing, and no investment commitments required.

However, if you have a home loan with significant interest payments, an active HRA component, or a disciplined investment portfolio that regularly maxes out Section 80C and 80D, the Old Regime can still outperform.

The best approach is always a numbers-first comparison: calculate your exact taxable income and projected deductions under both regimes before locking in your choice - ideally at the start of April each financial year.

Frequently Asked Questions

Which tax regime is better for a salaried person in FY 2025-26?

For salaried individuals with a gross income up to Rs 12.75 lakh and no significant deductions (no home loan, minimal 80C investments), the New Tax Regime is typically better. With the Rs 75,000 standard deduction and Rs 60,000 Section 87A rebate, zero tax applies on income up to Rs 12.75 lakh. Those with deductions exceeding Rs 3.25 lakh should compare both regimes carefully.

What are the new tax regime slabs for FY 2025-26?

The new tax regime slabs for FY 2025-26 are: Nil (up to Rs 4L), 5% (Rs 4L–8L), 10% (Rs 8L–12L), 15% (Rs 12L–16L), 20% (Rs 16L–20L), 25% (Rs 20L–24L), and 30% (above Rs 24L). A 4% Health and Education Cess applies on computed tax.

Can I switch between the old and new tax regime every year?

Salaried employees without business income can switch between regimes every financial year when filing their ITR. However, individuals with business or professional income can only opt out of the New Regime once. Once they revert to the New Regime, they cannot switch back to the Old Regime again. File Form 10-IEA before the ITR due date to opt out.

What deductions are available under the new tax regime?

The New Tax Regime allows: Standard Deduction of Rs 75,000 for salaried individuals, employer's NPS contribution under Section 80CCD(2), Agniveer Corpus Fund deduction under Section 80CCH, and family pension deduction of Rs 25,000. Most popular deductions - including Section 80C, 80D, HRA, and Section 24(b) home loan interest - are not available.

Is there zero tax up to Rs 12 lakh in FY 2025-26?

Yes - under the New Tax Regime. With net taxable income up to Rs 12 lakh, the enhanced Section 87A rebate of Rs 60,000 offsets all tax liability. For salaried individuals, the standard deduction of Rs 75,000 means a gross salary of up to Rs 12.75 lakh can be tax-free. Note: This rebate is not available for special rate income (e.g., capital gains under Section 111A/112A).

Are HRA and LTA available in the new tax regime?

No. House Rent Allowance (HRA) and Leave Travel Allowance (LTA) exemptions are not available under the New Tax Regime. If HRA forms a significant part of your salary structure and you pay substantial rent, the Old Regime may result in lower tax outgo - factor this into your breakeven calculation.

Is the new tax regime better for senior citizens?

It depends. The Old Regime offers Senior Citizens (60-80 years) a basic exemption of Rs 3 lakh and Rs 5 lakh for Super Senior Citizens (80+), plus Section 80TTB deduction of up to Rs 50,000 on interest income. If a senior citizen's total income is below Rs 12 lakh with limited deductions, the New Regime's Rs 60,000 rebate is more beneficial. Those with high interest income or significant investment deductions should compare both regimes numerically.
