Applies to
Micro & Small (not Medium)
With written agreement
45 days
Without agreement
15 days
Effective from
AY 2024-25

In plain English

If you buy from a Micro or Small enterprise, you have to clear the bill in 45 days (15 days when there's no written agreement) — otherwise that expense is not allowed as a deduction this year. You only get to claim it in the year you actually pay. Medium enterprises are not covered.

What this section covers

Clause (h), inserted in Section 43B by the Finance Act, 2023 with effect from AY 2024-25, deals with amounts payable by an assessee to a Micro or Small enterprise (Medium enterprises are NOT covered) for goods supplied or services rendered. The deduction is allowed only when the amount is actually paid, and the proviso permitting payment by the due date of return does NOT apply to clause (h). Payment must therefore be made within the time-limit u/s 15 of the MSMED Act — 45 days where a written agreement specifies a credit period (max 45), and 15 days where there is no written agreement.

The legal text

“Notwithstanding anything contained in any other provision of this Act, a deduction otherwise allowable… in respect of— … (h) any sum payable by the assessee to a micro or small enterprise beyond the time limit specified in section 15 of the Micro, Small and Medium Enterprises Development Act, 2006, shall be allowed… only in computing the income… of that previous year in which such sum is actually paid by him…”

NotesThe 43B(h) MSME-payment trigger is restated within Section 37 of the Income-tax Act, 2025 as part of the consolidated 'allowable on actual payment' rules. The link to Section 15 of the MSMED Act, 2006 and the exclusion of the due-date-of-return proviso are retained.

Common confusion

Clause (h) does NOT apply to Medium enterprises — only Micro and Small. The buyer must verify the supplier's Udyam status as on the date of supply, not on the date of payment.
