Tax Savings Calculator India – Old vs New Regime (FY 2025-26)
A salaried individual earning ₹12,00,000 with ₹2,75,000 in total deductions (80C: ₹1.5L + 80D: ₹25K + NPS: ₹50K + Std Ded: ₹50K) pays ₹0 tax under the new regime (₹12L rebate) and approximately ₹72,800 under old regime. At this income level, the new regime is clearly better. The breakeven point where old regime starts winning is typically around ₹15-18 lakh income with ₹4+ lakh in deductions.
Old vs New Tax Regime: Which Should You Choose? (FY 2025-26)
Union Budget 2025 made the new tax regime significantly more attractive by raising the basic exemption to ₹4 lakh, increasing the Section 87A rebate to ₹60,000 (making income up to ₹12 lakh tax-free), and enhancing the standard deduction to ₹75,000 for salaried individuals. The new regime is now the default option for FY 2025-26 (Assessment Year 2026-27) – you must actively opt for the old regime by filing Form 10-IEA before the ITR filing deadline.
However, the old regime still wins for many taxpayers who have substantial deductions under Section 80C, 80D, HRA exemption, home loan interest (Section 24b), and NPS contributions (80CCD). Senior citizens (60-80 years) get a higher basic exemption of ₹3 lakh under the old regime and ₹50,000 under Section 80TTB for interest income. Effective tax planning requires evaluating both regimes based on your specific deduction profile every year. Your employer deducts TDS based on your declared regime choice – submit the right declaration at the start of the financial year to avoid excess deductions or shortfalls.
Income Tax Slabs: New vs Old Regime (FY 2025-26)
| Income Slab | New Regime Rate | Old Regime Rate |
|---|---|---|
| Up to ₹2.5 lakh | 0% | 0% |
| ₹2.5L – ₹3L | 0% | 5% |
| ₹3L – ₹4L | 0% | 5% |
| ₹4L – ₹5L | 5% | 5% |
| ₹5L – ₹7L | 5% | 20% |
| ₹7L – ₹8L | 5% | 20% |
| ₹8L – ₹10L | 10% | 20% |
| ₹10L – ₹12L | 10% | 30% |
| ₹12L – ₹16L | 15% | 30% |
| ₹16L – ₹20L | 20% | 30% |
| ₹20L – ₹24L | 25% | 30% |
| Above ₹24L | 30% | 30% |
Key change in Budget 2025: Under the new regime, a rebate of ₹60,000 under Section 87A makes income up to ₹12 lakh effectively tax-free. With ₹75,000 standard deduction, salaried individuals with gross salary up to ₹12,75,000 pay zero tax under the new regime. This is a significant shift – most taxpayers earning below ₹13 lakh should choose the new regime.

Income Tax Questions Answered
What are the new income tax slabs for FY 2025-26 under the new regime?
The new tax regime slabs for FY 2025-26 (AY 2026-27) as per Union Budget 2025 are: up to ₹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 rebate under Section 87A of ₹60,000 makes income up to ₹12 lakh effectively tax-free. The standard deduction is ₹75,000 for salaried individuals, making the effective tax-free threshold ₹12,75,000.
When should I choose the old tax regime over the new regime?
Choose the old regime when your total deductions and exemptions (Section 80C, 80D, HRA, home loan interest under Section 24, NPS under 80CCD) significantly reduce your taxable income. As a general rule, if your total deductions exceed ₹3.75-4.25 lakh (the breakeven point varies by income level), the old regime typically saves more tax. Salaried individuals with HRA claims, home loan interest, and full 80C utilisation often benefit more from the old regime.
What deductions are available under Section 80C?
Section 80C allows deductions up to ₹1.5 lakh per financial year for investments including EPF (employee contribution), PPF, ELSS mutual funds, 5-year tax-saving FDs, NSC (National Savings Certificate), Sukanya Samriddhi Yojana, life insurance premiums, tuition fees for up to 2 children, and home loan principal repayment. This section is available only under the old tax regime. Under the new regime, only employer EPF contribution under 80CCD(2) is allowed.
How does HRA exemption work under the old regime?
HRA (House Rent Allowance) exemption under the old regime is the minimum of three amounts: actual HRA received from employer, 50% of basic salary for metro cities (40% for non-metro), or actual rent paid minus 10% of basic salary. This exemption is not available under the new regime. If you live in a rented accommodation in a metro city and your rent is substantial, HRA exemption alone can save ₹50,000-₹1,50,000 or more in tax, making the old regime significantly better.
What is the standard deduction for FY 2025-26?
The standard deduction for FY 2025-26 is ₹75,000 under the new tax regime (increased from ₹50,000 by Union Budget 2024) and ₹50,000 under the old tax regime. This flat deduction is available to all salaried employees and pensioners without any proof of expenditure. Under the new regime, the ₹75,000 standard deduction combined with the ₹12 lakh rebate threshold effectively makes income up to ₹12,75,000 tax-free.
Is NPS contribution tax-deductible under both regimes?
Under the old regime, NPS contributions qualify for deduction under Section 80CCD(1) within the ₹1.5 lakh 80C limit, plus an exclusive additional ₹50,000 under Section 80CCD(1B). Under the new regime, only employer NPS contributions under Section 80CCD(2) – up to 10% of salary – are deductible. Employee self-contributions to NPS do not get any tax benefit under the new regime. This makes NPS particularly valuable for old regime taxpayers.
How is health and education cess calculated on income tax?
A Health and Education Cess of 4% is levied on the total income tax liability (including any surcharge). For example, if your calculated tax is ₹1,00,000, the cess adds ₹4,000, making the total tax ₹1,04,000. This cess applies under both old and new regimes and cannot be avoided through any deduction. It funds healthcare and education infrastructure across India.
Can I switch between old and new tax regime every year?
Yes, salaried individuals and those with non-business income can switch between the old and new tax regime every financial year when filing their ITR. The new regime is the default – you must actively opt out by filing Form 10-IEA to choose the old regime. However, individuals with business or professional income can switch from new to old regime only once in their lifetime. The choice should be evaluated annually based on your deduction profile for that specific year.
