Section 437 of the Income-tax Act, 2025

← Section 436  ·  Section 438 →

What this section does

Sub-section (1) entitles an assessee due a refund to simple interest at 0.5% for every month or part of a month, for the periods set out in a three-row Table: refunds out of tax collected at source under section 394, advance tax, or tax treated as paid under section 390(5) run from 1 April of the year following the tax year where the return was filed by the section 263(1) due date, and otherwise from the date the return was furnished; refunds out of tax paid under section 266 run from the later of the return date or the payment date; and any other case runs from the date or dates on which the excess over the demand in the section 289 notice was paid. Sub-section (2) denies interest under rows 1 and 2 where the refund is less than 10% of the tax determined under section 270(1) or on regular assessment, and sub-section (3) gives interest from the date of the assessee's application where a row 1 refund follows an order on an application under section 288(1) (Table Sl. No. 11). Sub-section (4) adds a further 3% per annum where a refund arises from giving effect to an order under section 359, 363, 365(10), 368, 377 or 378 otherwise than by fresh assessment or reassessment, running from the day after the section 286(1) time limit expires, with sub-section (5) excluding any period the refund was withheld under section 438(3). Sub-section (6) gives a deductor 0.5% a month on refunds of amounts paid under Chapter XIX-B, from the date of the prescribed claim or the date of payment of tax where the refund follows a specified appellate order. Sub-sections (7) to (11) exclude delay attributable to the assessee or deductor, make the senior Commissioner's decision on that exclusion final, adjust the interest up or down when the underlying amount changes on a later order, and require a notice of demand — deemed a section 289 notice — for excess interest already paid.

Why it is there

It compensates the taxpayer for money held by the department, at a fixed monthly rate, and adds a higher additional rate where the department is slow to give effect to an appellate order. The exclusions for delay attributable to the assessee and the small-refund threshold keep the compensation to genuine departmental holding of funds.

Nos. 9 and 10) to the date of refund, excluding any period the refund was withheld under section 438(3)Sub-section (4), with sub-section (5)

What this means in practice

Filing by the section 263(1) due date is worth money: it starts interest on an advance tax or TCS refund from 1 April following the tax year, whereas a late return starts it only from the date of filing. Small refunds under rows 1 and 2 carry no interest at all if they are below 10% of the tax determined, so the threshold is worth checking before disputing an interest computation. Where the department has simply to give effect to an appellate order, the extra 3% a year under sub-section (4) is the lever for delay — but any period during which the refund was withheld under section 438(3) is taken out. If the refund is delayed for reasons attributable to you, that period is excluded, and the Commissioner's decision on how much of the delay is yours is final under sub-section (8).

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 firm's tax determined under section 270(1) is Rs 50 lakh and its refund is Rs 4 lakh, which is 8% of that tax. Sub-section (2) denies interest altogether, the refund being less than 10% of the tax determined; on a refund of Rs 6 lakh the same firm would carry interest at 0.5% for every month or part of a month. Where interest does run on advance tax or on tax collected under section 394, it starts from 1 April of the year following the tax year only if the return went in by the section 263(1) due date — file it late and row 1(b) of the Table starts the clock only from the date the return was actually furnished. The further 3% per annum in sub-section (4) is narrower still: it is available only where an appellate order is given effect otherwise than by making a fresh assessment or reassessment.

Where you meet this section

You meet it in the refund itself — the interest is computed and added when the refund is granted on an intimation or assessment — and, if it is later reduced under sub-section (9), in a notice of demand for the excess which sub-section (11) deems to be a notice under section 289. A deductor meets it through the prescribed refund claim form under sub-section (6), from which its interest runs.

The words themselves

he shall, subject to the provisions of this section, be entitled to receive, in addition to the refund, simple interest thereon calculated at the rate of 0.5% for every month or part of a month

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.

Case law carried across

Read this before you rely on it. Every decision below was decided under the Income-tax Act, 1961. It appears here because it is tagged to a 1961 provision that the department’s own mapping carries to section 437. That is an inference we have drawn, not a holding on the new section: where the words changed in the move, the reasoning may not survive. Treat this as the place to start looking, not as authority on the 2025 Act.
