Income tax calculator — Old vs New, FY 25-26 & FY 26-27
Compare your tax under both regimes for FY 2025-26 (Income Tax Act 1961) or FY 2026-27 (Income Tax Act 2025, effective 1 April 2026). Marginal relief is shown explicitly. Capital gains handled separately from salary. No email required to see your result.
Salaried
Compare regimes with ₹75K standard deduction (new) vs Chapter VI-A deductions (old).
Freelancers
Mixed income — salary + capital gains + dividend split into separate buckets.
Business owners
Capital gains, surcharge marginal relief, take-home math — all in one view.
Before any deductions or exemptions
What you'll get
More than a number — a derivation you can defend.
Side-by-side regime comparison
Both Old and New regimes computed simultaneously. We tell you which is better and by how much, with a one-line explanation of why.
Marginal relief breakdown
If your income just crosses a rebate or surcharge threshold, we show you exactly how much marginal relief saved you. Most calculators hide this.
Effective rate + take-home
Not just the final tax number — your effective rate, breakdown of slab tax, surcharge, cess, and approximate take-home.
Section references that auto-switch
Calculate for FY 2025-26 — see Section 24(b), Section 80C, Section 87A. Calculate for FY 2026-27 — see Section 22, Section 123, Section 156. The Income Tax Act 2025 renumbering is built in.
How we differ
What other calculators get wrong — and what we get right.
Marginal relief shown explicitly
Most consumer calculators apply marginal relief silently in the backend. We show you the exact amount the legislative protection saved you, with the underlying math.
Special-rate income handled separately
Capital gains under Section 111A (STCG 20%), Section 112A (LTCG 12.5%), and crypto under Section 115BBH (30%) are taxed at fixed rates — not slab rates. The ₹60,000 rebate under the new regime does NOT apply to these. We compute them in a separate bucket so the math is correct.
HRA correctly excluded from new regime
Section 10(13A) HRA exemption is unavailable under the new regime. Many calculators incorrectly subtract HRA when computing new regime tax — ours does not.
No phone or email gate
Your tax breakdown is visible the moment your inputs are complete. Email is optional, only if you want a PDF report and edge-case insights from our team.
Both Acts handled — section references switch automatically
Choose FY 2025-26 and we cite Income Tax Act 1961 sections. Choose FY 2026-27 and we cite Income Tax Act 2025 sections. The economic rules are unchanged through the transition; only section numbering changes — and we handle it.

For edge cases — capital gains splits, multiple house properties, foreign income, business income with presumptive vs regular accounting choices, or surcharge marginal relief boundary scenarios — a focused validation review with our team is available. The calculator is designed to surface where edge cases start, not to replace professional consultation when they do.
