Conclusion
For FY 2025-26, the new tax regime is the clear winner for most salaried employees earning up to ₹15 LPA. The combination of zero tax up to ₹12.75 lakh, lower slab rates, and no investment hassle makes it attractive. However, if you have significant deductions (HRA + 80C + 80D + home loan), the old regime can still save more — especially at salaries above ₹20 LPA.
