Old vs New Tax Regime: Which Saves You More in FY 2025-26?
The new tax regime became the default from FY 2023-24, but the old regime still results in lower tax for many salaried Indians with substantial deductions. This guide shows you exactly where the crossover happens with worked examples at every salary level.
Every April, millions of salaried Indians face the same question: should I stick with the New Tax Regime or opt for the Old one? The answer is not universal. It depends on your salary, your deductions, whether you pay rent, have a home loan, or invest in NPS. For a detailed slab-by-slab breakdown, see our income tax slabs explainer.
The New Regime offers lower tax rates but strips away most deductions. The Old Regime has higher rates but lets you claim 80C, 80D, HRA, home loan interest, NPS, and more. The tipping point varies, but generally: if your qualifying deductions exceed ₹ 3.75-4.25 lakh, the Old Regime typically results in lower tax. You can see a side-by-side comparison in our old vs new tax regime comparison.

Worked Examples by Salary Level
₹10 Lakh CTC — New Regime Results in Lower Tax
At ₹10 lakh, the New Regime with standard deduction of ₹75,000 gives taxable income of ₹9.25 lakh. Tax = ₹46,250 before cess. Under the Old Regime, even with ₹1.5 lakh in 80C and ₹25,000 in 80D, taxable income is ₹8.25 lakh — tax = ₹82,500 before cess (at higher slab rates). New Regime saves approximately ₹35,000.
₹15 Lakh CTC — Depends on Deductions
This is the crossover zone. Under the New Regime, tax is approximately ₹1.3 lakh. Under the Old Regime with ₹1.5 lakh (80C) + ₹50,000 (80CCD1B) + ₹25,000 (80D) + ₹1.5 lakh (HRA in metro) = ₹3.75 lakh total deductions, tax is approximately ₹ 1.35 lakh. The regimes are nearly equal at this level. Add home loan interest, and the Old Regime pulls ahead.
₹20 Lakh CTC — Old Regime Often Results in Lower Tax
At ₹20 lakh with typical deductions of ₹4-5 lakh (80C + NPS + 80D + HRA + home loan), the Old Regime saves ₹50,000-80,000 over the New Regime. The higher your deductions, the larger the gap. Check your exact numbers with the calculator above.
₹50 Lakh CTC — Old Regime Dominates (if deductions are high)
At ₹50 lakh, the Old Regime with maximized deductions (₹1.5 lakh 80C + ₹50,000 NPS + ₹50,000 80D + ₹2 lakh home loan + ₹3 lakh HRA = ₹7.5 lakh) can save ₹1.5-2.5 lakh over the New Regime. However, surcharge considerations kick in above ₹50 lakh, making the comparison more complex. The calculator handles this automatically, including marginal relief.
Decision Framework: Quick Rules
Which regime should you choose based on salary?
- Salary under ₹12 lakh: New Regime (almost always tax-free with 87A rebate)
- Salary ₹12-15 lakh, no HRA/home loan: New Regime
- Salary ₹15 lakh+ with HRA + 80C + 80D: Run the calculator — likely Old Regime
- Salary ₹20 lakh+ with home loan + HRA + NPS: Old Regime (typically saves ₹50K-2L+)
For a detailed understanding of how each slab works under both regimes, read our income tax slabs FY 2025-26 guide with worked examples at four different income levels.
Key Deductions That Tip the Scale
HRA Exemption (Section 10(13A))
HRA is often the single largest deduction for salaried metro employees. If you earn ₹15+ lakh and pay ₹25,000+ rent per month in a metro, your HRA exemption could be ₹1.5-3 lakh. This deduction alone can make the Old Regime better. Not available in the New Regime. Use our HRA Calculator to compute your exact exemption, or read the full HRA exemption guide for detailed rules and worked examples.
Section 80C (₹1.5 Lakh)
EPF contributions (employee share), ELSS mutual funds, PPF, life insurance premium, and children's tuition fees all qualify. Most salaried employees automatically exhaust a portion of this through EPF, which you can track with our EPF Calculator. Top up with ELSS for the remaining amount — see our ELSS vs PPF comparison to decide where to invest. Model the growth with our Step-Up SIP Calculator to model ELSS investments, or read the Step-Up SIP guide for a detailed strategy on increasing your investments each year.
Home Loan Interest (Section 24b — ₹2 Lakh)
If you have a home loan, the interest deduction of up to ₹2 lakh is only available in the Old Regime. Use our EMI Calculator to see how much interest you pay annually.
NPS (Sections 80CCD(1B) and 80CCD(2))
Self-contribution of up to ₹50,000 under 80CCD(1B) is Old Regime only. But employer contribution under 80CCD(2) works in both regimes, making it the most valuable tax-saving tool for New Regime taxpayers. Use our NPS Calculator to estimate your retirement corpus and see how much the 80CCD(1B) deduction saves under the Old Regime.

Frequently Asked Questions
Which tax regime is better for a salary of ₹12 lakh in FY 2025-26?
At ₹12 lakh gross salary, the New Tax Regime typically results in lower tax. The Section 87A rebate makes income up to ₹12 lakh effectively tax-free under the New Regime (after the ₹75,000 standard deduction). Under the Old Regime, you would need deductions exceeding ₹4 lakh to beat zero tax, which is difficult for most salaried individuals.
What are the new income tax slabs for FY 2025-26 under the New Regime?
The New Regime slabs for FY 2025-26 are: 0-4 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. Section 87A rebate makes income up to ₹12 lakh tax-free.
Can I claim HRA exemption under the New Tax Regime?
No. HRA exemption under Section 10(13A) is not available in the New Tax Regime. This is one of the biggest deductions that pushes high-rent-paying individuals toward the Old Regime. If you pay substantial rent (₹25,000+ per month in a metro), the HRA exemption alone could be ₹1.5-3 lakh, which significantly reduces tax under the Old Regime.
What deductions are allowed in the New Tax Regime?
The New Tax Regime allows only two deductions: a standard deduction of ₹75,000 for salaried individuals, and employer NPS contribution under Section 80CCD(2) (up to 10% of basic + DA for private sector, 14% for government). All other deductions — 80C, 80D, 80CCD(1B), HRA, LTA, home loan interest — are not available.
At what salary level does the Old Regime become better than New Regime?
There is no single salary level — it depends on your deductions. As a rough guideline: if your total deductions (80C + 80D + HRA + home loan interest + NPS) exceed ₹3.75-4.25 lakh, the Old Regime typically results in lower tax liability. This typically happens for salaried individuals earning ₹15 lakh or more who pay rent in a metro, have a home loan, and actively invest in tax-saving instruments.
What is the surcharge on income tax for high-income earners?
Surcharge applies on base tax for income above ₹50 lakh: 10% for ₹50L-1Cr, 15% for ₹1Cr-2Cr, 25% for ₹2Cr-5Cr. For income above ₹5 crore, the Old Regime charges 37% surcharge while the New Regime caps it at 25%. Marginal relief ensures your total tax doesn't jump disproportionately when crossing a threshold.
Can I switch between Old and New Tax Regime every year?
Yes, salaried employees can switch between regimes every financial year. The New Regime is the default — you must actively opt for the Old Regime with your employer or while filing your ITR. Non-salaried individuals with business income can switch only once in their lifetime.
How does employer NPS contribution work under the New Regime?
Employer NPS contribution under Section 80CCD(2) is the only significant investment-linked deduction available in the New Regime. Your employer can contribute up to 10% of your Basic + DA (14% for government employees) to NPS, and this amount is deductible from your taxable income. This makes it a powerful tax-saving tool for New Regime taxpayers.
Is the ₹50,000 NPS deduction (80CCD1B) available in the New Regime?
No. The additional ₹50,000 deduction under Section 80CCD(1B) for self-contributions to NPS is not available in the New Tax Regime. Only the employer contribution under 80CCD(2) is allowed. If you contribute to NPS for the tax benefit, you need to factor in that this deduction is only useful under the Old Regime.
