If the input increases, ask whether the output should also increase.

If gross income is Rs. 12,00,000 and old regime deductions are Rs. 2,00,000, the page compares slab tax after deductions under both regimes. The example is not a promise of eligibility, salary fixation, tax liability or government fee. It only demonstrates how the arithmetic works with the visible inputs.
