Why it matters
The regime that saves you most isn't the same for everyone
The new regime wins for most salaried people now, especially after the FY 2025-26 rebate. But if you claim heavy HRA, 80C, home-loan interest and 80D, the old regime can still come out ahead by tens of thousands. Don't guess — run both side by side for your exact deductions.
