Section 408 of the Income-tax Act, 2025

Section 408 — Instalments of advance tax and due dates. Successor to s.211 of the 1961 Act.

Where this section sits

Section 408 is in Chapter XIX — Collection and Recovery of Tax, which runs from section 390 to section 430.

← Section 407  ·  Section 409 →

What this section does

Sub-section (1) requires all assessees liable to pay advance tax, other than those in sub-section (2), to pay it on the current income calculated in the manner laid down in section 405 in four instalments during each financial year, with the due dates and amounts in the Table: on or before the 15th June, not less than 15% of the advance tax; on or before the 15th September, not less than 45% as reduced by the amount paid in the earlier instalment; on or before the 15th December, not less than 75% as reduced by amounts paid in earlier instalments; and on or before the 15th March, the whole amount as reduced by amounts paid in earlier instalments.

Sub-section (2) provides a single instalment for an assessee who declares profits and gains as per section 58(2) (Table: Sl. No. 1 or 3): the whole amount of advance tax on the current income, calculated in the manner laid down in section 405, on or before the 15th March of each financial year. Sub-section (3) provides that any amount paid by way of advance tax on or before the 31st March is treated as advance tax paid during the financial year ending on that day for all the purposes of the Act.

Why it is there

Tax on the year's income is collected during the year rather than after it, and the instalment ladder spreads that collection so that three quarters of the liability is in before the year's last quarter begins. The percentages are cumulative rather than equal so that a taxpayer whose income arrives late in the year is not required to pay early on income he has not earned. Sub-section (2) recognises that a presumptive assessee's income is a function of the year's turnover and cannot sensibly be estimated in instalments, and sub-section (3) closes the gap between the 15th March instalment and the year end.

Who it applies to

The figures, and what each one turns on

Read the condition in the same row. A figure quoted without it is a wrong answer with a citation attached.

What this means in practice

The percentages are cumulative and are floors, not fixed instalments: each row says "not less than" the stated percentage of the whole advance tax, reduced by what has already been paid, so by 15 September the total paid must reach 45% and by 15 December 75%, whatever the split between instalments. Paying more early is permitted and reduces what is due later. Sub-section (2) is a complete substitute, not a concession added on top: an assessee declaring under section 58(2) (Table: Sl. No. 1 or 3) has no June, September or December obligation at all and pays the whole amount on or before 15 March. Sub-section (3) matters where a payment slips past the last instalment date — it still counts as advance tax of that financial year if made on or before 31 March, for all the purposes of the Act, though it does not undo the fact that the 15 March instalment date was missed.

An example

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

A company estimates its advance tax for a financial year at forty lakh rupees. It must have paid at least six lakh by 15 June, at least eighteen lakh in aggregate by 15 September, at least thirty lakh in aggregate by 15 December, and the whole forty lakh by 15 March, each instalment being reduced by what was already paid. An individual who declares profits and gains as per section 58(2) (Table: Sl. No. 1) on the same estimated liability pays nothing on the first three dates and the whole forty lakh on or before 15 March. If either pays a further two lakh on 28 March, sub-section (3) treats that as advance tax paid during that financial year.

Where you meet this section

You meet this every quarter in the advance tax challans you pay and in the advance tax schedule of your return, where each instalment is reported against its due date. It is the provision against which a shortfall is measured when interest for deferment or short payment of advance tax is computed in an intimation or assessment.

The words themselves

Not less than 45% of such advance tax, as reduced by the amount, if any, paid in the earlier instalment.

Section 408(2), 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.

Circulars of the Board on this section

A circular binds the department, not you and not a court. Every one below was written under the 1961 Act; it reaches this section because the department’s own concordance carries the provision it names to this one.

See the circulars index.

Notifications that reach this section

A notification is made under a power the Act gives and, within that power, is law. These too were made under the 1961 Act and are placed here by the department’s concordance.
