The Finance Act 2023 inserted Section 43B(h), which stipulates that any sum owed to Micro, Small and Medium Enterprises (MSME) for goods supplied or services given may be deducted in the same year if it is paid within the deadline stipulated by the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006.This amendment aims to address the issue of working capital scarcity in the MSME industry and promote prompt payments to micro and small businesses. The assessment year 2024–2025 and any following years will be covered by this change, which will come into effect on April 1, 2024.The newly added clause (h) states that any sum payable by the assessee to a MSME beyond the time limit set in Section 15 of the MSMED Act, 2006, is eligible for deduction.This deduction is applicable in the previous year when the sum is actually paid. Clause (h) of Section 45B essentially states that any sum payable by a larger enterprise or entity to a registered MSME beyond the stipulated deadlines won’t be considered a deductible expense in the year the liability was incurred. This clause is applicable when an enterprise is buying goods or taking services from an enterprise registered under the MSMED Act, 2006. Notably, the registration of the buyer under the MSMED Act, 2006, is not mandatory. Clause (h) of Section 43B comes into effect from April 1, 2024.As per Office Memorandum No. 5/2(2)/2021-E/P and G/Policy dated July 2, 2021, wholesale and retail traders are entitled to Udyam registration only for the benefit of Priority Sector Lending. So, Section 43B(h) is not applicable for dues outstanding to traders as per the MSMED Act’s definition of enterprise.Business enterprises are required to pay MSMEs within 45 days, as per section 15 of the MSMED Act, 2006, depending on the presence of a written agreement. In the absence of a written agreement, payment should be made within 15 days. In case there is a written agreement, payment shall be made as per the agreed-upon timeline, not exceeding 45 days.
