Section 101 of the Income-tax Act, 2025

Section 101 — Total income. Successor to s.66 of the 1961 Act.

Where this section sits

Section 101 is in Chapter VI — Aggregation of Income, which runs from section 101 to section 107.

← Section 100  ·  Section 102 →

What this section does

The section is a single inclusion rule. In computing the total income of an assessee, all income on which no income-tax is payable under Chapter XVII-A is to be included. It creates no charge of its own; it directs that income of that description forms part of the total income figure even though the Act does not levy tax on it.

Why it is there

The Act distinguishes between income that never enters total income and income that enters it but bears no tax. This section places the second category inside the computation, so that total income remains a complete measure of what the assessee has earned rather than a figure netted of amounts the Act has chosen not to tax.

Who it applies to

What this means in practice

Not being taxed and not being included are different things, and this section says which applies: income on which no income-tax is payable under Chapter XVII-A is still included in total income. Nothing here makes such income chargeable — any charge must come from elsewhere — so the effect is confined to the total income figure and to whatever turns on it.

Where you meet this section

A taxpayer does not meet this section directly in a notice or a form. It works inside the computation of total income, and shows up only as the reason an amount appears in the total income figure although no tax is charged on it.

The words themselves

In computing the total income of an assessee, there shall be included all income on which no income-tax is payable under Chapter XVII-A
Section 101, Income-tax Act, 2025.

What people get wrong

What this replaced

The correspondence is the Income Tax Department’s own, from its comparison utility for the 1961 and 2025 Acts. A renumbering is the easy half; whether the words changed is the half that decides cases.
