MSME Form 1 Due 31 October 2026: A Practical Checklist Before September Closes

September is almost over. If your company buys from micro or small enterprises, the next few weeks matter. For the April to September 2026 half-year, qualifying companies must file MSME Form 1 by 31 October 2026. The filing is not based on your company's size. It is triggered by delayed payments to eligible micro or small enterprise suppliers. What MSME Form 1 is MSME Form 1 is a half-yearly return under the Companies Act framework for specified companies that delay payments to micro or small enterprise suppliers beyond the permitted period. The Ministry of Corporate Affairs amended the reporting order on 15 July 2024. The notification states that only specified companies with payments pending to a micro or small enterprise for more than 45 days from acceptance or deemed acceptance must furnish MSME Form 1.

Run the check if your entity is a company and you purchased goods or services from suppliers registered as micro or small enterprises. Ask five questions: Is the supplier a micro or small enterprise, rather than a medium enterprise?What Udyam details and classification do you have on record?When were the goods or services accepted or deemed accepted?Was payment pending beyond the applicable limit?Does that delay bring your company within the filing trigger? If your finance system only stores a vendor name and GSTIN, add Udyam status and enterprise classification to the vendor master. Why 45 days matters The MSMED Act contains delayed-payment protections for micro and small enterprises. Where there is a written agreement, the agreed payment period cannot extend beyond 45 days from acceptance or deemed acceptance. If there is no written agreement, the statutory timing can be shorter. Ministry of MSME guidance also states that delayed payment can attract compound interest with monthly rests at three times the RBI-notified bank rate, subject to the Act. The 45-day line can affect filing, cash planning, supplier relationships, interest exposure and tax treatment. A practical example Assume a private limited company buys components from a registered small enterprise. The invoice is ₹4,00,000. Goods are accepted on 1 August 2026. The written credit term is 45 days. Payment goes out on 25 September. The invoice crossed the 45-day limit before payment. Do not remove it from your review simply because the balance was cleared before 30 September. The updated form captures transaction-level payment information, so build the return from the full half-year payment dataset and confirm the exact treatment with your filing professional.

Clean the vendor masterAsk suppliers for current Udyam details. Record the enterprise classification and registration number. Do not assume every business that calls itself an MSME is a micro or small enterprise for this filing. 2. Use acceptance date, not only invoice dateYour ageing report may count from invoice date. The legal framework refers to acceptance or deemed acceptance. Document how your system determines that date. 3. Pull every payment made during the half-yearDo not review only open creditors. A payment may have been made during the period after crossing the limit. 4. Document disputesIf goods were rejected, quantities differed or services were disputed, preserve emails, debit notes and inspection records. 5. Reconcile with the general ledgerThe working paper should reconcile with supplier ledgers and the accounts payable control account. Investigate differences before filing. 6. Confirm the authorised signatoryCheck the digital signature and MCA V3 access of the person who will sign. Do not discover a DSC issue on deadline day. Do medium enterprises count? The reporting requirement discussed here focuses on micro and small enterprise suppliers. Medium enterprises should not automatically be included. This is why actual Udyam classification matters. What if all payments were within the limit? The July 2024 MCA amendment narrowed the filing requirement to specified companies with payments pending beyond 45 days. If your review shows no trigger, retain the working paper that supports that conclusion. MSME Form 1 and Section 43B(h) are different MSME Form 1 is a corporate reporting requirement. Section 43B(h) of the Income-tax Act affects when certain payments to micro and small enterprises are allowed as a tax deduction if payment timing does not meet the MSMED Act requirements. The datasets overlap, but the legal tests and consequences are not identical. Use one clean supplier-payment dataset, then apply the correct rule to each compliance question. Common mistakes Checking only invoices still unpaid on 30 September.Treating every Udyam supplier as micro or small without checking classification.Using invoice date without reviewing acceptance or deemed acceptance.Keeping Udyam details in email rather than the vendor master.Ignoring disputed invoices without evidence.Starting the exercise in the final week of October.Assuming the accountant and company secretary are using the same vendor data.

FAQs Is the October 2026 deadline 31 October?Yes. The April to September half-year is followed by the 31 October filing deadline. Does an LLP file MSME Form 1?The MCA order applies to specified companies. An LLP is not a company under the Companies Act. Is there a minimum overdue amount?The 2024 amendment frames the trigger around qualifying delayed payments, not a minimum rupee threshold. Can I rely only on the creditor ageing report?No. You also need supplier classification, acceptance dates and payment history. What founders should do now Ask finance for every transaction with a micro or small enterprise supplier during April to September, showing acceptance date, invoice amount, payment date, days outstanding and current balance. If that report is difficult to produce, the bigger problem is not the form. It is the quality of your accounts payable data.
