Calculate Your Income Tax
Deductions (Old Regime Only)
How to Use the Income Tax Calculator
This tool compares your tax under both regimes for FY 2025-26 as per the latest Income Tax Act provisions updated with Budget 2025.
Step 1 — Enter Income and Age
Enter gross annual income and select age group. Age affects old regime slabs (seniors get higher exemption).
Step 2 — Enter Deductions
Enter deductions under 80C, 80D, 80CCD(1B), home loan (Sec 24b), HRA, and others. These apply only to old regime. Employer NPS applies to both.
Step 3 — View Comparison
Get side-by-side comparison with slab breakup, rebate, surcharge, cess, and a clear winner showing savings amount.
CA Tip: The breakeven is ~₹3.75 lakh in total deductions. If old regime deductions exceed this, old regime likely saves more. Below this, new regime is better. The ICAI recommends comparing with actual numbers, not rules of thumb.
