Tax Calculators

Calxo’s tax calculators help you figure out what you’ll actually pay this financial year — not the rough number your HR portal flashes at appraisal time. Every tool reflects the post-Budget-2025 slabs for FY 2025-26 (AY 2026-27), the updated ₹60,000 87A rebate under the new regime, the ₹75,000 standard deduction for salaried employees, and marginal relief at the ₹12 lakh threshold.

What you can calculate here

• Income tax under both new (default) and old regimes, with surcharge, cess and rebate
• Old vs new regime comparison — the calculator shows both side-by-side so you can pick the cheaper one for your deduction stack
• HRA exemption for salaried employees in metro and non-metro cities (coming soon)
• Capital gains tax for equity, debt and real estate (coming soon)

How the math is verified

Slab rates are pulled directly from the Finance Act 2025 / Union Budget 2025 announcement. Surcharge slabs follow the Income Tax Department’s published 10/15/25/37% structure with the 25% cap under the new regime. Marginal relief at ₹12 lakh is implemented per the rule that tax cannot exceed (taxable income − ₹12,00,000) for incomes just above that threshold. Cess is 4% on (tax + surcharge), unchanged since 2018.

Each calculator page shows the exact slab-by-slab breakdown so you can cross-check against your Form 16, AIS or actual ITR computation. If a number is off by more than ₹100 from your CA’s calculation, it’s probably one of three things: standard deduction not applied, deductions claimed under the wrong regime, or a deduction your CA used that the new regime doesn’t permit.

Start with the income tax calculator — it’s the right starting point for almost every salaried, freelance or business taxpayer in India.
