New regime is better if you have few deductions (HRA not applicable, minimal 80C investments). Old regime wins if you claim full ₹1.5L under 80C, HRA exemption, and NPS deduction. Rule of thumb: if your total deductions exceed ₹3.75 lakh, Old regime likely saves more tax.

From FY 2025-26, income up to ₹12 lakh is effectively tax-free under the New regime due to Section 87A rebate (₹60,000 max rebate). Salaried employees get an additional ₹75,000 standard deduction, making salary up to ₹12.75 lakh fully tax-free.
