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

Choosing between tax systems has become more critical than ever with the latest budget mandates. Our Old vs New Tax Regime Calculator Excel FY 2025-26 is designed to provide an instant, data-driven answer to the ultimate question: Which one saves you more money?

For the current financial year, the New Tax Regime has been strengthened. It includes a basic exemption limit of ₹4 Lakh and an enhanced Standard Deduction of ₹75,000. These “default” features offer significant relief to middle-income earners. However, the Old Tax Regime still holds a hidden advantage for those with heavy investments.

If you claim substantial deductions under Section 80C or 80D, the traditional system might still be your winner. The same applies if you have high HRA and Home Loan Interest (Section 24b).

Income Tax Calculation Old vs New: FY 2025-26 Comparison

To determine your tax liability, you must compare the total tax payable under both systems. The New Regime offers lower slab rates. It also provides a higher Standard Deduction of ₹75,000. The Old Regime remains beneficial for those with significant investments in 80C, 80D, and HRA.

• Old Regime Calculation: Total Income – (HRA + 80C + 80D + Standard Deduction ₹50k) = Taxable Income.
• New Regime Calculation: Total Income – (Standard Deduction ₹75k + 80CCD(2)) = Taxable Income.
• The Verdict: If your total deductions exceed ₹3.75 Lakh to ₹4 Lakh, the Old Regime usually wins.

Important Update: For FY 2025-26, the Standard Deduction has been increased to ₹75,000 for the New Regime. Combined with the tax rebate, salaried individuals earning up to ₹12.75 Lakh pay ZERO tax under the New Regime.
