Old vs New Income Tax Regime Comparison — FY 2025-26 (AY 2026-27)
Educational tool — not a tax return. This uses the individual income-tax slabs, standard deduction and Section 87A rebate applicable for FY 2025-26 (AY 2026-27) as per the Finance Act, 2025. It assumes salary/other-source income taxed at slab rates and does not cover special-rate income (capital gains, lottery, etc.), surcharge on dividend/capital-gains income (capped at 15%), or every possible deduction. Please confirm your final numbers with us before filing.

Quick details before you begin

This tool is free to use. We just ask for a few contact details first, so our team can follow up if you'd like help planning your taxes or filing your return. No income or financial data is ever sent to us — only the contact details below, and only if you choose to submit them.

We collect only the contact details above — never the income figures you use inside the tool.

Income & Profile
Deductions Available Only Under the Old Regime These reduce your Old Regime tax only — the New Regime does not allow them (except 80CCD(2) above)

    Disclaimer: This is a self-help planning aid, not a filed tax return or tax advice. Calculations use FY 2025-26 (AY 2026-27) slab rates, the Section 87A rebate (with marginal relief under the New Regime only), and surcharge with marginal relief, and assume income taxed at normal slab rates only. It does not account for capital gains, presumptive income, Chapter VI-A caps you may have already used elsewhere, or your specific eligibility to switch regimes (business-income taxpayers face restrictions under Section 115BAC that salaried taxpayers do not). Aggarwal Abhishek & Co. does not certify these figures — please have us review your actual computation before filing or before locking in a regime choice.
