New vs Old Tax Regime: What to Choose?

For AY 2026-27, the New Tax Regime is the DEFAULT. Here's a quick comparison:

Feature New Tax Regime (Default) Old Tax Regime
Standard Deduction Rs. 75,000 Rs. 50,000
80C Deductions Not allowed Up to Rs. 1.5 lakh
80D (Health Insurance) Not allowed Up to Rs. 25,000
HRA Exemption Not allowed Allowed
Home Loan Interest (24b) Not allowed Up to Rs. 2 lakh

Rule of Thumb: If your total deductions (80C + 80D + HRA + home loan) exceed Rs. 3.5-4 lakh, the Old Regime is usually better. Otherwise, stick with the New Regime.
