A quick guide

Use the number with context

The answer is only useful when you know what it includes and what it leaves out.

How to use it

  1. Choose tax period from your records.
  2. Choose domestic-company regime from your records.
  3. Enter taxable income from your records or declared policy assumptions.
  4. Enter book profit for mat warning from your records or declared policy assumptions.

Formula

Normal tax = taxable income × selected rate; add surcharge and 4% cess; compare with MAT when applicable.

This is a company scenario, not a tax audit or concessional-regime eligibility decision.

Make it concrete

Worked example

A company entering ₹50,00,000 taxable income under a declared 25% regime receives a rate, cess and MAT comparison.
