Form MSME-1 — Half-Yearly Return

Every Indian company that pays a Micro or Small Enterprise supplier more than 45 days after acceptance falls under Section 405 of the Companies Act read with the Specified Companies Order, 2019. Once you are in that net, Form MSME-1 — the half-yearly return of outstanding dues to MSE suppliers — has to be filed by 30 April for the October-March window and by 31 October for the April-September window. The 45-day clock is the only trigger; turnover, capital, and sector do not matter.

The form looks routine, but the exposure underneath it is not. Section 16 of the MSMED Act, 2006 charges compound interest at three times the RBI bank rate on every overdue day, and Section 43B(h) of the Income Tax Act denies the entire expense deduction in the year of accrual if MSE dues are not cleared on time. MSME-1 is the disclosure layer that statutory auditors, tax auditors, and acquirers all reconcile against — getting it wrong shows up everywhere.

At a Glance

• Who must file: Every company with Micro or Small Enterprise supplier dues outstanding beyond 45 days from the date of acceptance, regardless of size, turnover, or sector.
• Governing law: Section 405 Companies Act, 2013 read with the Specified Companies (Furnishing of information about payment to micro and small enterprise suppliers) Order, 2019, and MSMED Act, 2006 Sections 15, 16, 22, and 23.
• Frequency: Half-yearly. October-March return is due by 30 April; April-September return is due by 31 October.
• Filing portal: MCA V3 portal e-form MSME-1, signed with director DSC and certified by a practising CA, CS, or CMA.
• Filing fee: Nil within the due date. Additional fees apply for late filing per the Companies (Registration Offices and Fees) Rules.
• The 45-day test: Days count from the day of acceptance or deemed acceptance under Section 2(b) MSMED — not from invoice date. Only Micro and Small suppliers enter the test; Medium suppliers do not.
• Turnaround: 7-10 working days end-to-end including supplier scrub, ageing, and filing once the data is shared.

What's New for FY 2026-27

MSME-1 was once a quiet half-yearly disclosure. Three changes since FY 2023-24 have moved it to the centre of corporate compliance, and FY 2026-27 is the first full year where all of them are tested side by side.

• V3 portal only: Form MSME-1 is filed exclusively on the MCA V3 portal. Web-based filing has replaced the older offline utility; director DSC and a practising professional's certification are validated in real time.
• Section 43B(h) in full operation: Effective from AY 2024-25, the disallowance has now run through two full assessment cycles. CBDT FAQs and ITAT decisions through 2025 confirm that MSE classification on the date of accrual is what triggers the denial — a later reclassification by the supplier does not save the deduction.
• Udyam re-verification: Udyam Registration Numbers issued before April 2021 had to be re-validated; many suppliers received fresh URNs through 2024-25. Your supplier master must carry the current URN, not the legacy one.
• Tax audit clause 22 cross-link: Form 3CD clause 22 reports MSE payments delayed beyond Section 15 MSMED timelines. From AY 2025-26, these figures must reconcile with MSME-1 disclosures and Note 47 of Schedule III — three sources, one truth.
• Acquirer diligence baseline: Section 43B(h) and Section 16 exposures now appear as standard line items in every diligence questionnaire. Missing or Nil MSME-1 filings against a populated payable ledger are an instant red flag.
• DPDP Act housekeeping: Supplier master data is often personal data of the proprietor. Storage, processing, and disclosure must align with the Digital Personal Data Protection Act, 2023 — a quiet operational layer that has emerged since 2024.

Section 43B(h) is the substantive cost. MSME-1 is just the disclosure. The numbers must match — three places, one truth.

Why MSME-1 Matters More Now

• Tax cost of Section 43B(h): If MSE expense is unpaid beyond the Section 15 MSMED timeline on the accrual date, the entire amount is added back to taxable income that year, deductible only in the year of actual payment. For a company in the 25.17% regime, ₹1 crore of unpaid MSE dues converts to a ₹25.17 lakh tax bill.
• Compound interest at 3x bank rate: Section 16 MSMED imposes compound interest with monthly rests at three times the RBI bank rate. At a 6.50% bank rate, that is 19.5% per annum compounded monthly — and the interest is non-deductible under Section 23 MSMED.
• Section 405 penalty: Failure to file MSME-1 attracts up to ₹25,000 on the company and ₹25,000 to ₹3,00,000 on every officer in default. The penalty is for non-disclosure only; the underlying interest and tax exposure stays separate.
• Audit qualification: Statutory auditors qualify the audit report where MSE classification is incomplete or Section 16 interest is not booked. The qualification carries forward into every funding round.
• Acquirer diligence: M&A teams now demand the last three years of MSME-1 acknowledgements alongside Form 3CD clause 22 and Note 47 trade-payables ageing. If the three numbers disagree, the deal slows.
• AIS / TIS cross-validation: Supplier-side reporting under PAN-linked TDS and GST flows into the buyer's AIS. The tax department can reconstruct ageing externally, making your internal disclosures testable.

How It Actually Works

The form is short. The work behind it is not. A defensible MSME-1 filing requires a supplier-level data layer, not a one-line trial-balance figure.

Step 1: Supplier Master Scrub

We pull your complete supplier master and tag every supplier with PAN, GSTIN, address, and Udyam Registration Number. Each URN is verified live on the Udyam portal — Micro, Small, or Medium classification is confirmed from the source, not from the supplier's invoice footer. Suppliers without a URN are tagged Other and excluded from the MSE pool. This is the most underestimated step; misclassification here cascades into every later number.

Step 2: Half-Year Ageing Freeze

At the 31 March or 30 September cut-off, we run an invoice-wise ageing on every MSE supplier. The starting date is the day of acceptance under Section 2(b) MSMED — usually the date of delivery confirmation or, where there is no written objection within 15 days, the date of deemed acceptance. Balances overdue beyond 45 days are isolated, with bucketing at 46-90, 91-180, and 180+ days.

Step 3: Reason-Code Tagging

Each overdue invoice is tagged with a reason for delay — quality dispute, working-capital constraint, internal approval failure, or pending reconciliation. Supporting correspondence is catalogued against each entry. The reasons go into the form; the documentation stays in your audit pack.

Step 4: MSME-1 Form Preparation

The V3 form is filled with the supplier-wise schedule, total overdue principal, and reasons. A board resolution authorising the filing is prepared and signed. Where the period covers a prior delay, a ratifying resolution is drafted alongside.

Step 5: MCA V3 Portal Filing

The form is uploaded to V3, signed with director DSC, and certified by the practising professional. SRN is generated and the acknowledgement timestamp is captured. Within the due date the filing fee is nil; beyond the due date, additional fees per the Companies (Registration Offices and Fees) Rules apply.

Step 6: Audit Pack and Tax Memo

A reconciliation pack ties the MSME-1 disclosure to Form 3CD clause 22, Schedule III Note 47, and the trade-payables sub-ledger. A standalone Section 43B(h) memo computes the disallowance and a Section 16 MSMED memo computes the compound interest. Your auditor sees one consistent set of numbers.

A Real Example: Mid-Sized Manufacturer

Take a private limited company with ₹85 crore turnover and ₹6 crore of trade payables at 31 March 2026. The accounts team identifies ₹4.2 crore as payable to MSE suppliers after Udyam verification, of which ₹1.10 crore is overdue beyond 45 days.

• MSE supplier base: 142 suppliers verified on the Udyam portal — 38 classified Micro, 76 Small, 28 Medium. Only the 114 Micro and Small balances enter MSME-1.
• Overdue principal: ₹1.10 crore across 67 invoices. Ageing splits to ₹62 lakh in 46-90 days, ₹34 lakh in 91-180 days, and ₹14 lakh beyond 180 days.
• Section 16 interest: At 19.5% per annum compounded monthly — three times the 6.50% RBI bank rate — the interest accrual on the half-year stock works out to approximately ₹9.8 lakh. This is booked under Interest on MSME dues and disclosed in Note 47.
• Section 43B(h) disallowance: Of the ₹4.2 crore MSE payables, ₹1.10 crore relates to expense accrued in FY 2025-26 and unpaid at year-end. Under Section 43B(h), the entire ₹1.10 crore is added back to taxable income, increasing tax at 25.17% by approximately ₹27.7 lakh.
• Filing outcome: MSME-1 is filed by 30 April 2026 disclosing the ₹1.10 crore with supplier-wise schedule. Form 3CD clause 22 reports the same figure. Note 47 of Schedule III reconciles. SRN is preserved with the board pack.

The disclosure fee is nil. The substantive cost — Section 16 interest plus Section 43B(h) disallowance — is around ₹37.5 lakh. The number the board needs to see is the second one, not the first.

After You File: Audit and Diligence Reconciliation

The filing acknowledgement is not the end of the cycle. Four downstream uses of the MSME-1 number determine whether the disclosure holds up under audit, tax, and deal scrutiny.

• Statutory audit Note 47: Schedule III Note 47 in the financial statements reproduces the MSE overdue principal and Section 16 interest. The auditor reconciles to the MSME-1 SRN before signing the accounts.
• Tax audit Form 3CD clause 22: Clause 22 reports MSE payments delayed beyond Section 15 MSMED timelines. From AY 2025-26, this figure must equal the MSME-1 overdue principal for the corresponding half-year.
• Section 43B(h) computation: The unpaid portion at 31 March of MSE expense accrued during the year is added back to taxable income. The Section 43B(h) memo delivered with the filing is the working paper for your tax return.
• Section 16 interest in the ledger: The compound interest is booked as a P&L expense under Interest on MSME dues with a matching liability. Non-deductibility under Section 23 MSMED is captured in the tax computation.
• Acquirer and lender diligence: Three years of MSME-1 acknowledgements, Form 3CD extracts, and Note 47 disclosures are standard diligence requests. Consistency across the three is what closes the line item.

Where It Goes Wrong

• Treating Nil as default: Companies file Nil MSME-1 without ever running a Udyam check on the supplier master. The Nil is defensible only if you can show the test was performed and produced zero overdue MSE balances.
• Using invoice date as start: The 45-day clock runs from acceptance or deemed acceptance, not from invoice date. Where there is a written agreement, the agreed credit period applies, capped at 45 days. Counting from invoice date is the most common silent error.
• Missing Udyam re-verification: Suppliers registered under the old MSME regime had to migrate to Udyam, and pre-April 2021 URNs needed re-validation. Stale URNs in the supplier master pull the wrong classification.
• Not booking Section 16 interest: The interest accrues whether or not the supplier demands it. Auditors expect to see it booked; not booking it triggers a qualification and a tax audit comment.
• Losing Section 43B(h) silently: Many tax teams catch the disallowance only at the tax-audit stage in October — too late to plan payment. Mid-year monitoring saves the deduction.
• Late catch-up without resolution: Where prior half-years were missed, a single late filing without a ratifying board resolution invites Section 405 scrutiny. The resolution is cheap insurance.
• Pulling Medium suppliers in-scope: Only Micro and Small enter the 45-day test under Section 15 MSMED. Including Medium suppliers inflates MSME-1 and creates wrong numbers in downstream disclosures.
• MSME-1 and Form 3CD mismatch: MSME-1, Form 3CD clause 22, and Note 47 of Schedule III must agree. Mismatches surface in diligence and in tax department reconciliations.

If the Udyam check has never been performed, a Nil MSME-1 is indefensible. The Nil only protects you if you can prove the test.

How to Get Started

Share your supplier master, trade payables sub-ledger, and the half-year cut-off date with our team. We sign a non-disclosure agreement, set up a secure data room, and begin the Udyam verification within 48 hours. Most filings are ready for upload within 7-10 working days, comfortably ahead of the 30 April or 31 October deadline.

If you have missed earlier half-years, share the prior cut-off dates and we will sequence the catch-up filings with a board resolution ratifying the delay. Where Section 43B(h) exposure is significant, we run a parallel cash-flow plan to clear the most damaging balances before year-end and preserve the deduction. The disclosure side and the substantive tax side are handled together — that is the only way the numbers will hold up under audit and diligence.
