Not a substitute for professional advice. This calculator gives an estimate for resident individual taxpayers based on the slab rates, rebate limits and due dates in force for FY 2025-26 and FY 2026-27 under current government guidance. It does not cover HUFs, companies, LLPs, non-residents, marginal relief on surcharge, or every deduction and exemption. Section 234B interest here is illustrative only — the actual figure depends on your assessment date. For a return you're about to file or pay tax against, please verify the exact figures with a tax professional.
