Income Tax Slab Visualizer

See exactly how much tax each slab contributes to your total bill, old regime vs new regime, with surcharge and cess.

The Income Tax Slab Visualizer breaks your Indian income tax bill down slab by slab, so you can see precisely how much of the total comes from the 5% band, the 20% band, the 30% band and so on. It runs the old regime and the new regime (Section 115BAC) side by side for FY 2025-26, applying the standard deduction, the Section 87A rebate, surcharge with marginal relief, and the 4% health and education cess. It is built for salaried employees, pensioners and freelancers who want to understand where their tax actually comes from rather than just seeing one final number.

Why use Income Tax Slab Visualizer

• Per-slab contribution

  Shows the rupee tax each individual slab adds, not just the total.

• Both regimes at once

  Old and new regime slabs are computed together so the cheaper option is obvious.

• Rebate, surcharge and cess included

  Applies Section 87A, surcharge with marginal relief and 4% cess the way the Act does.

Common use cases

• A salaried employee earning ₹18 lakh wants to see how much of the bill comes from the 30% slab before deciding whether extra 80C investments are worth it.
• A pensioner aged 62 compares the old regime's higher ₹3 lakh basic exemption against the new regime's wider slabs and ₹75,000 standard deduction.
• A consultant crossing ₹50 lakh checks how the 10% surcharge and marginal relief change the marginal cost of the next rupee earned.
