Income Tax Calculator FY 2025-26: Old vs. New Regime Comparison
The Income Tax regime for the Financial Year 2025-26 (Assessment Year 2026-27) presents a critical choice for every taxpayer: selecting between the long-established Old Tax Regime with its extensive deductions, and the concessional-rate New Tax Regime (which is now the default).
Our comprehensive Income Tax Calculator is the ultimate tool to compare both options side-by-side, helping you decide which structure saves you the most tax money.
Decoding the Two Regimes
Understanding the core difference is the first step in effective tax planning:
| Feature | Old Tax Regime | New Tax Regime (Default) |
| Tax Slabs | Higher rates, fewer slabs. | Lower, more numerous slabs. |
| Deductions | Allows major deductions (Sec 80C, 80D, HRA, Sec 24(b), etc.). | No major exemptions allowed, except Standard Deduction (₹50,000) and employer NPS contribution. |
| Rebate u/s 87A | Taxable Income (TI) up to ₹5 Lakh is tax-free. | Taxable Income (TI) up to ₹7 Lakh is tax-free. |
Why Deductions Still Matter (Old Regime)
The calculator’s true value lies in assessing your specific investment profile. For many middle and high-income earners, the substantial deductions available under the Old Regime still lead to a lower final tax outgo, despite the higher slab rates.
The key deductions that heavily influence the outcome:
- Home Loan Interest (Sec 24(b)): The ability to claim up to ₹2,00,000 in interest paid on a self-occupied property often tilts the balance in favor of the Old Regime.
- Section 80C: Investments like EPF, PPF, Life Insurance, and Home Loan Principal Repayment provide a deduction of up to ₹1,50,000.
- HRA & Standard Deduction: The calculator factors in the ₹50,000 Standard Deduction (available in both regimes for salaried persons) and your specific House Rent Allowance (HRA) exemption.
- Health Insurance (Sec 80D): Deductions for medical insurance premiums (up to ₹25,000/₹50,000) further reduce your Old Regime tax base.
Maximizing Your ₹7 Lakh Exemption (New Regime)
The New Tax Regime is simplified and highly beneficial for individuals who have minimal investments or are new to the workforce. With the full rebate under Section 87A, your entire tax liability is zero if your Taxable Income does not exceed ₹7 Lakh.
This regime is the simplest choice as it eliminates the need for detailed documentation for investment proofs.
When to Choose Which Regime
- Choose the New Regime (Default): If your total claimed deductions (80C, 80D, 24b, HRA, etc.) are less than roughly ₹2,00,000 to ₹2,50,000.
- Choose the Old Regime: If you claim substantial deductions, especially if you have a Home Loan or maximize your ₹1.5 Lakh 80C limit.

Frequently Asked Questions
What is the difference between the Old and New Tax Regime for FY 2025-26?
The primary difference lies in the tax rates and the availability of deductions. The old tax regime allows you to reduce your taxable income through various exemptions like HRA, LTA, and deductions under Section 80C or 80D, but it features higher tax slab rates. In contrast, the new tax regime, which is the default system for FY 2025-26, offers much lower tax rates and wider slabs but requires you to forgo most of these traditional exemptions. While the old regime rewards those with significant investments and home loans, the new regime provides a simpler structure with a higher tax-free threshold.
Is the New Tax Regime better than the Old Tax Regime in 2025?
Whether the new regime is better depends entirely on your total income and the amount of tax-saving investments you make. For salaried individuals with gross income up to ₹12.75 lakh, the new regime is often more beneficial due to the increased standard deduction of ₹75,000 and the enhanced Section 87A rebate which makes income up to ₹12 lakh tax-free. However, if you have a home loan interest of ₹2 lakh and total Section 80C investments of ₹1.5 lakh, the old regime might still result in lower tax liability. You should use a comparative calculator to find your specific “breakeven point” where the old regime becomes more profitable.
How much income is tax-free in India for FY 2025-26?
Under the new tax regime for FY 2025-26, an individual with a total income of up to ₹12 lakh pays zero tax because of the enhanced rebate under Section 87A. For salaried employees, this limit effectively increases to ₹12.75 lakh after including the ₹75,000 standard deduction. In the old tax regime, the basic exemption limit remains ₹2.5 lakh for individuals below 60 years, though a rebate under Section 87A ensures no tax is paid on taxable income up to ₹5 lakh. Senior citizens under the old regime enjoy higher basic exemption limits of ₹3 lakh and ₹5 lakh respectively.
What are the new tax slabs for FY 2025-26 (AY 2026-27)?
The new tax regime slabs for the current financial year start with a 0% rate for income up to ₹4 lakh. Income between ₹4 lakh and ₹8 lakh is taxed at 5%, while the bracket from ₹8 lakh to ₹12 lakh attracts a 10% rate. The rates increase to 15% for income between ₹12 lakh and ₹16 lakh, 20% for the ₹16 lakh to ₹20 lakh range, and 25% for income between ₹20 lakh and ₹24 lakh. Any income exceeding ₹24 lakh is taxed at the maximum rate of 30%. These revised slabs are designed to provide more disposable income to middle-class taxpayers compared to previous years.
Can I switch from the New Tax Regime to the Old Tax Regime?
Yes, you can choose between the two regimes at the time of filing your Income Tax Return. Salaried individuals who do not have business income have the flexibility to switch between the old and new regimes every financial year based on which one is more beneficial for them. However, taxpayers with income from a business or profession only have a one-time option to opt out of the new regime. If they choose to switch back to the new regime in a future year, they may not be allowed to opt for the old regime again in subsequent years.
