How the Income Tax Calculator works
Places the same taxable income on the new-regime and old-regime slabs for FY 2025-26 and FY 2026-27, applies rebate where the encoded rules allow it, and shows which regime is cheaper for that fact pattern.
Formula / method. Tax = sum of income in each slab × slab rate, plus cess. New regime uses the current new-regime slabs and standard deduction. Old regime subtracts the deductions you enter (80C, 80D, HRA, and so on) first.
When to use it. Use it in January–March when you still have time to change investments or regime choice, and again before filing. It is not a return.
How to run a comparison
- Open Income Tax Calculator from Home search, the Finance Studio hub, or this URL.
- Copy amounts, rates or dates from a document you already have — not a round marketing figure.
- Read the headline result and any breakdown (schedule, slabs, or intermediate rows).
- Change one input at a time so you can see what actually moves the answer.
- Cross-check with a related calculator below, then confirm statutory rates before you act.
Nothing you type is uploaded for server-side processing. Save or screenshot an output if you need it later; we do not keep a server-side history.
Notes and assumptions
Surcharge edge-cases, special-rate income, and clubbing are only as modelled. Always re-check against the Finance Act / ITR utility.
Results are estimates for education and planning only. They are not financial, tax, medical, or legal advice. Slabs, scheme rates and product terms change; verify against official notifications or a qualified professional before acting.
