Act before year-end. When Finance Act 2023 introduced Section 43B(h) into the Income Tax Act, it created a new compliance obligation for every Indian business that purchases goods or services from Micro or Small Enterprises: pay within the time limits prescribed under the MSMED Act or lose the tax deduction for that year. Three financial years on, Section 43B(h) non-compliance remains one of the most common — and most avoidable — tax disallowances found during NDS Advisors’ tax audit and advisory engagements across Mumbai and Pune. The reason is straightforward: many businesses have not built a systematic process to identify which vendors hold Udyam Registration as Micro or Small Enterprises, track payment due dates for each MSME invoice, and flag outstanding balances before the March 31 year-end. Without that system, the disallowance under Section 43B(h) is invisible until the tax audit — at which point it increases taxable income, creates additional tax liability, and requires disclosure in the Form 3CD report. What Is Section 43B(h) and How Does It Work? Section 43B of the Income Tax Act lists categories of expenditure that are deductible only when actually paid, not when accrued. The Finance Act 2023 added clause (h) to this section, effective from FY 2023-24 (AY 2024-25 onwards). Section 43B(h) in plain terms: Any sum payable to a Micro or Small Enterprise registered under the MSMED Act 2006 for goods or services supplied shall be allowed as a deduction only if paid within the time limits prescribed under Section 15 of the MSMED Act. If not paid within those limits, the sum is disallowed in the year it was incurred and becomes deductible only in the year in which it is actually paid. The critical word is “accrual basis” — Section 43B(h) overrides the normal accounting practice of recognising expenses when incurred. Even if your books show the expense and payable in full compliance with accounting standards, if the actual cash payment to the MSME vendor did not happen within the prescribed window, the disallowance applies for income tax purposes. Which Vendors Are Covered? The Micro and Small Distinction This is the most important initial determination. The provision applies only to Micro and Small Enterprises as classified under the MSMED Act 2006. It does not apply to Medium Enterprises or to unregistered vendors. Enterprise Category Investment in Plant & Machinery Annual Turnover Sec 43B(h) Applies? Micro Enterprise ≤ Rs. 1 crore ≤ Rs. 5 crore YES ✓ Small Enterprise ≤ Rs. 10 crore ≤ Rs. 50 crore YES ✓ Medium Enterprise ≤ Rs. 50 crore ≤ Rs. 250 crore NO ✗ Unregistered vendor (no UDYAM) Not applicable Not applicable NO ✗ The MSME classification is based on the vendor’s own Udyam Registration certificate. A buyer cannot independently determine a vendor’s MSME classification — it must be verified from the UDYAM certificate issued by the Ministry of MSME. This creates a practical compliance step: collect the UDYAM certificate from every vendor before recording them in the accounting system, and note whether they are Micro, Small, or Medium. Payment Timelines Under Section 43B(h) Section 43B(h) references the payment timelines set out in Section 15 of the MSMED Act 2006. Situation Payment Deadline Key Rule Written agreement exists between buyer and MSME supplier 45 days from date of acceptance of goods/services Contract cannot extend beyond 45 days — any clause giving longer credit is invalid No written agreement (or agreement silent on payment terms) 15 days from date of acceptance of goods/services 15 days is the “appointed day” under MSMED Act — no exceptions What Counts as “Acceptance”? Physical receipt and actual acceptance of goods or completion of services → date of acceptance Delivery made, no objection raised within 15 days → date of delivery = deemed date of acceptance For services: date the service was completed and accepted by the buyer For partial deliveries: date of acceptance of each delivery consignment separately ⚠ Critical distinction: The 15-day / 45-day clock starts from acceptance date, not from the invoice date. If goods are delivered on July 1 but the invoice is dated July 10, the clock starts from July 1. Many businesses get this wrong when tracking payment due dates. How Section 43B(h) Disallowance Is Computed: A Worked Example Worked Example — FY 2026-27 Company ABC (Mumbai-based trader) has MSME vendor XYZ registered as a Small Enterprise under UDYAM. ABC purchases goods from XYZ with a written payment agreement of 30 days from acceptance. Invoice Date of Acceptance Due Date (30 days) Amount (Rs.) Paid by 31 Mar? Invoice 1 1 Feb 2027 3 Mar 2027 5,00,000 Yes — paid 28 Feb Invoice 2 10 Feb 2027 12 Mar 2027 3,00,000 No — outstanding 31 Mar Invoice 3 1 Mar 2027 31 Mar 2027 2,00,000 Yes — paid 31 Mar Invoice 4 15 Mar 2027 14 Apr 2027 4,00,000 Not yet due at 31 Mar Section 43B(h) disallowance for FY 2026-27 = Rs. 3,00,000 (Invoice 2 only) Invoice 1 and Invoice 3 paid within due date → Allowed. Invoice 4 not yet due at March 31 → Allowed in this year. Invoice 2’s Rs. 3,00,000 is added back to taxable income for FY 2026-27. At 25% tax rate → additional
