Section 409 of the Income-tax Act, 2025

Section 409 — When assessee is deemed to be in default. Successor to s.218 of the 1961 Act.

Where this section sits

Section 409 is in Chapter XIX — Collection and Recovery of Tax, which runs from section 390 to section 430.

← Section 408  ·  Section 410 →

What this section does

It identifies three failures that make a person a deemed assessee in default in respect of the instalment or instalments concerned: not paying, on the date specified in section 408, an instalment of advance tax he is required to pay by an order of the Assessing Officer under section 407(1) and (4); not sending the Assessing Officer the intimation under section 407(8) on or before the date the unpaid instalment falls due; and not paying, on the basis of his own estimate of current income, the advance tax payable under section 407(9). Each limb is tied to section 407 — the Assessing Officer's order and the assessee's response to it — rather than to advance tax the assessee computes for himself.

Why it is there

Where the Assessing Officer has ordered advance tax, the assessee must either pay the ordered instalment, or tell the officer why a lower estimate applies and pay on that estimate; failing either, the section makes him an assessee in default so that the recovery machinery can be used.

What this means in practice

If an order under section 407 has been served on you and you disagree with the figure, the safe course is to send the section 407(8) intimation before the instalment falls due and pay on your own estimate under section 407(9) — doing neither, or doing one without the other, puts you in default. Default is measured instalment by instalment, so a single missed instalment is enough for the consequences to attach in respect of it. The section defines the status only; the consequences of being an assessee in default come from elsewhere in this Chapter.

An example

Illustrative only, and invented for this page. The figures are chosen to show the rule biting, not taken from any real matter.

The Assessing Officer passes an order under section 407(1) requiring a firm to pay advance tax, and an instalment falls due on a date specified in section 408. The firm, believing its current income will be far lower, pays nothing — but it also fails to send the Assessing Officer the intimation under section 407(8) on or before that due date, and pays nothing on the basis of its own estimate under section 407(9). Each of clauses (a), (b) and (c) is failed, and the firm is a deemed assessee in default in respect of that instalment, so the recovery machinery opens. Sending the intimation alone would not have saved it either: clause (c) still requires payment of advance tax on the assessee's own estimate.

Where you meet this section

You meet it only after an order of the Assessing Officer under section 407 requiring advance tax — in the demand and recovery that follow a missed instalment, and in the intimation under section 407(8) you were expected to have sent by that instalment's due date. A shortfall in advance tax you computed for yourself is not this section's concern.

The words themselves

A person shall be deemed to be an assessee in default, if such person— (a) does not pay on the date specified in section 408, any instalment of the advance tax that he is required to pay by an order of the Assessing Officer under section 407(1) and (4)

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.
