MSME Form-1 Filing: Half-Yearly Return for Outstanding Payments

Every company in India that delays a payment to a Micro or Small Enterprise supplier beyond 45 days must file MSME Form 1 (MSME-1) on the MCA portal, twice a year. The April 2026 filing, covering the period from October 1, 2025 to March 31, 2026, is due by April 30, 2026. This is not optional. Non-filing attracts a penalty of ₹20,000 plus ₹1,000 for every day of continuing default. With Section 43B(h) of the Income Tax Act now disallowing deductions for delayed MSME payments, the financial consequences of ignoring this compliance have doubled. Whether you run a Private Limited Company, a Public Limited Company, or an OPC, this guide covers everything you need to know about MSME Form 1: who must file, the step-by-step process, penalties, and the income tax implications for 2026.

What is MSME Form 1 (MSME-1)?

MSME Form 1, officially designated as MSME-1, is a half-yearly return that companies file on the Ministry of Corporate Affairs (MCA) portal to report outstanding payments due to Micro and Small Enterprise (MSE) suppliers. It was introduced through the Companies (Furnishing of Information about Payment to Micro and Small Enterprise Suppliers) Order, 2019, issued by the MCA on January 22, 2019.

The legal basis for this form lies in Section 405 of the Companies Act, 2013, which empowers the Central Government to require companies to furnish information about their business operations. When read with Rule 22 of the Companies (Acceptance of Deposits) Rules, 2014, and the provisions of the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006, the filing obligation becomes clear: if your company owes money to an MSME supplier for more than 45 days, you must report it.

The objective is transparency. The government wants to know which companies are delaying payments to small businesses - the backbone of India's economy. MSMEs contribute over 30% of India's GDP and employ more than 11 crore people. Delayed payments from larger companies choke their cash flow, and this form is one mechanism to monitor and address that problem.

Who Must File MSME Form 1?

The filing obligation applies to all companies registered under the Companies Act, 2013 - Private Limited Companies, Public Limited Companies, One Person Companies, Section 8 Companies, and government companies - that have outstanding payments to Micro or Small Enterprise suppliers exceeding 45 days from the date of acceptance or deemed acceptance of goods or services.

Note the specific trigger: it is not about all supplier payments. It is specifically about payments to suppliers registered as Micro Enterprises or Small Enterprises under the Udyam Registration system. Medium Enterprises are excluded from the scope of MSME Form 1. This distinction catches many companies off guard.

Entities That Must File

• Private Limited Companies with delayed MSME payments
• Public Limited Companies including listed entities
• One Person Companies (OPCs)
• Section 8 Companies (NGOs)
• Government companies under Section 2(45) of the Companies Act

Entities Exempt from Filing

• Limited Liability Partnerships (LLPs) - governed by LLP Act, 2008, not the Companies Act
• Partnership firms - not companies under the Companies Act
• Sole proprietorships - not corporate entities
• Companies with no outstanding payments to MSMEs beyond 45 days

MSME Classification in India (2026)

Before filing MSME Form 1, you need to understand which of your suppliers qualify as MSMEs. The classification was revised by the Government of India on June 26, 2020, and applies based on investment in plant and machinery or equipment and annual turnover. Both criteria must be satisfied simultaneously.

Only suppliers classified as Micro or Small Enterprises trigger the MSME Form 1 obligation. If your vendor is a Medium Enterprise, delayed payments to them do not need to be reported in MSME-1 - although the payment discipline requirements under the MSMED Act still apply for interest purposes.

How do you verify a supplier's classification? Every registered MSME holds an Udyam Registration Certificate issued through the Udyam Registration portal. The certificate specifies whether the enterprise is Micro, Small, or Medium. You should collect this certificate from every supplier during vendor onboarding. If a supplier does not have Udyam Registration, they are not classified as an MSME under the current framework, and payments to them are outside the scope of MSME Form 1.

Filing Schedule and Due Dates for 2026

MSME Form 1 is filed twice a year - once for each half-year period. The deadlines are fixed and do not change based on the company's financial year. Here is the complete schedule.

For the April 2026 filing, companies must report all outstanding amounts due to Micro and Small Enterprise suppliers where the payment was pending beyond 45 days during the October 1, 2025 to March 31, 2026 period. Even if the payment was eventually made during the period but was overdue beyond 45 days at any point, it must be reported.

The October 2026 filing covers April 1, 2026 to September 30, 2026, with a deadline of October 31, 2026. Mark both dates on your compliance calendar now. Unlike annual filings where extensions are sometimes granted, MCA has historically not extended MSME Form 1 deadlines.

Is your company handling compliance tracking manually? For businesses with multiple filing obligations - ROC annual returns, DIR-3 KYC, GST returns, income tax, and now MSME-1 - a structured compliance calendar is essential. Missing even one deadline compounds into penalties and audit flags.

The 45-Day Payment Rule Explained

The 45-day rule is the foundation of MSME payment compliance and the trigger for MSME Form 1 filing. Understanding exactly how this works prevents both compliance failures and unnecessary filings.

How the 45-Day Clock Works

Under Section 15 of the MSMED Act, 2006, when a buyer purchases goods or receives services from an MSME supplier, the payment timeline depends on whether a written agreement exists:

• With a written agreement: Payment must be made within the period specified in the agreement, but this period cannot exceed 45 days from the date of acceptance or deemed acceptance
• Without a written agreement: Payment must be made within 15 days from the date of acceptance or deemed acceptance

What constitutes "acceptance"? If the buyer inspects goods and communicates acceptance, that date starts the clock. If the buyer fails to communicate acceptance or rejection within 15 days of delivery, the goods are deemed accepted under Section 2(b) of the MSMED Act. The 45-day payment window begins from this deemed acceptance date.

What Happens When You Exceed 45 Days?

Three consequences trigger simultaneously when payment crosses the 45-day mark:

1. Interest liability: Under Section 16 of the MSMED Act, the buyer must pay compound interest at three times the RBI bank rate (approximately 19.5% per annum in 2026) from the date the amount became due
2. MSME Form 1 reporting: The outstanding amount must be disclosed in the next half-yearly MSME-1 filing
3. Income tax disallowance: Under Section 43B(h), the expense cannot be claimed as a deduction until actually paid

The combined financial impact makes the 45-day rule one of the most consequential compliance requirements for companies with MSME vendors. A single delayed payment triggers three separate consequences across three different regulatory frameworks.

Step-by-Step Process to File MSME Form 1

Filing MSME Form 1 on the MCA portal is straightforward once you have gathered the required data. Here is the complete process for the April 2026 filing.

Step 1: Identify Outstanding MSME Payments

Review your accounts payable for the period October 1, 2025 to March 31, 2026. Filter all invoices from MSME-registered suppliers (Micro and Small Enterprises only) where payment was delayed beyond 45 days from the date of acceptance or deemed acceptance. Cross-reference against your vendor database to confirm Udyam Registration status.

Step 2: Collect Required Information

For each delayed payment, compile the following details:

• Name of the MSME supplier
• PAN of the MSME supplier
• Udyam Registration Number (format: UDYAM-XX-00-0000000)
• Outstanding amount as on the last date of the half-year period
• Date from which the amount became due
• Number of days of delay beyond the 45-day limit
• Reason for the delay in payment

Step 3: Log in to the MCA Portal

Visit www.mca.gov.in and log in using your company's registered credentials. Navigate to the e-filing section and select MSME Form 1 from the list of available forms.

Step 4: Fill in Company Details

Enter the company's CIN (Corporate Identification Number). The system auto-populates the company name, registered office address, and email. Verify the pre-filled information for accuracy. Select the half-year period you are filing for (October to March or April to September).

Step 5: Enter MSME Supplier Details

Add each MSME supplier with outstanding payments. Enter the supplier name, PAN, Udyam Registration Number, outstanding amount, due date, delay period, and reason. If you have multiple suppliers, each must be added as a separate entry. There is no limit on the number of supplier entries.

Step 6: Upload Supporting Documents

Attach any supporting documentation if required. While the form itself captures the essential data, maintaining internal records (aging reports, supplier correspondence, purchase orders) is recommended for audit purposes.

Step 7: Certify and Submit

The form must be certified by a director of the company using their Digital Signature Certificate (DSC). A practicing Company Secretary can also certify the filing. After digital signing, submit the form and note the SRN (Service Request Number) for your records. The filing fee for MSME Form 1 is ₹200.

Section 43B(h): Income Tax Impact of Delayed MSME Payments

This is where MSME payment compliance intersects with income tax law - and the consequences are severe. Section 43B(h) was inserted into the Income Tax Act, 1961, by the Finance Act, 2023, and has equivalent provisions under the new Income Tax Act, 2025. It fundamentally changes how businesses treat MSME-related expenses in their tax returns.

What Section 43B(h) Does

Section 43B(h) states that any sum payable to a Micro or Small Enterprise supplier is allowed as a deduction only in the year in which it is actually paid. If the payment is made within the time limit specified under Section 15 of the MSMED Act (i.e., within 45 days or the agreed period, whichever is shorter), the deduction is allowed on accrual basis in the year the expense is incurred. If the payment exceeds this limit, the deduction is deferred to the year of actual payment.

Practical Impact on Your Tax Liability

Consider this scenario: your company purchases raw materials worth ₹50 lakh from an MSME supplier in February 2026. The payment becomes due in March 2026 (within 45 days of acceptance). If you pay by March 31, 2026, the ₹50 lakh expense is deductible in FY 2025-26. If you pay in May 2026 - beyond 45 days - the deduction is disallowed in FY 2025-26 and shifts to FY 2026-27 (the year of actual payment).

The tax impact? At a 25% corporate tax rate, a ₹50 lakh disallowance increases your tax liability by ₹12.5 lakh for that assessment year. You eventually get the deduction when you pay, but the cash flow impact and timing difference can be substantial for businesses with large MSME procurement.

Connection Between MSME Form 1 and Section 43B(h)

The data you report in MSME Form 1 directly maps to potential Section 43B(h) disallowances. Tax auditors and the Income Tax Department can cross-reference your MSME-1 filings with your income tax returns to verify whether disallowances have been correctly applied. Filing MSME Form 1 accurately is no longer just a Companies Act compliance - it is also a self-declaration that feeds into your income tax assessment.

Penalties for Non-Compliance

The penalty framework for MSME Form 1 non-compliance operates across multiple laws. Here is a consolidated view of every financial consequence your company faces.

The cumulative impact is significant. A company that delays a ₹10 lakh payment to an MSME supplier for 6 months faces approximately ₹97,500 in interest (19.5% p.a. compounded monthly), a potential ₹2.5 lakh tax disallowance impact (at 25% tax rate), and MSME Form 1 penalties if the form is also filed late. Add legal costs if the supplier files a Samadhaan complaint, and the total cost of delayed payment easily exceeds 25% of the original invoice amount.

Is any delayed payment worth that kind of financial exposure? The math strongly favors paying MSME suppliers on time, even if it means prioritizing them over larger vendors in your payment cycle.

How to Check if Your Supplier is a Registered MSME

Accurate MSME Form 1 filing depends on correctly identifying which suppliers are registered MSMEs. Filing with incorrect vendor classifications wastes time and risks penalties for inaccurate data. Here are the practical steps to verify supplier status and build a reliable vendor database.

Method 1: Udyam Registration Portal

Visit udyamregistration.gov.in and use the verification tool. Enter the supplier's Udyam Registration Number to confirm their registration status and classification (Micro, Small, or Medium). The portal displays the enterprise name, type, registration date, and NIC codes.

Method 2: Request Certificate from Supplier

Ask each supplier to provide a copy of their Udyam Registration Certificate during vendor onboarding. This certificate clearly states the enterprise classification. Make it a standard part of your vendor registration process. Include a clause in your purchase orders requiring suppliers to disclose their MSME status.

Method 3: MSME Databank

The MSME Databank maintained by the Ministry of MSME also contains registration details. While this is primarily used for government procurement purposes, it can serve as a supplementary verification source. Cross-reference the data with your vendor's self-declaration.

Building an Internal MSME Vendor Database

For companies with a large vendor base, create a dedicated MSME vendor master in your accounting system. Tag each vendor with their Udyam Registration Number, classification (Micro/Small/Medium), and the date of last verification. Refresh this data annually, as suppliers may change classification based on updated investment and turnover figures. This database becomes your primary reference during MSME Form 1 preparation and Section 43B(h) computations at year-end.

Your finance team or Virtual CFO should review the vendor master before each half-yearly filing. New vendors added during the period need MSME status verification. Existing vendors may have graduated from Small to Medium Enterprise, which would remove them from MSME Form 1 scope.

Common Mistakes to Avoid When Filing MSME Form 1

Based on compliance patterns across thousands of company filings, these are the most frequent errors that trigger penalties or audit issues.

• Including Medium Enterprise suppliers: MSME Form 1 covers only Micro and Small Enterprises. Including Medium Enterprise data inflates your reported figures and creates unnecessary scrutiny
• Not verifying Udyam Registration status: Filing with incorrect or expired Udyam numbers leads to rejection or penalties for false information. Always verify on the portal before filing
• Missing the deemed acceptance rule: Many companies calculate the 45-day period from invoice date instead of acceptance or deemed acceptance date. The MSMED Act is clear - the clock starts from acceptance, not invoicing
• Ignoring the form when no payments are overdue: Good news - if all MSME payments are within 45 days, you do not need to file. But document this internally for audit purposes. A simple board note confirming zero reportable transactions protects you
• Filing without DSC: MSME Form 1 requires a Digital Signature Certificate from a director. Ensure DSC validity before the filing deadline. Expired DSCs are a common last-minute issue
• Not reconciling with Section 43B(h) computation: Your MSME-1 data should match your income tax computation for MSME payment disallowances. Discrepancies between the two filings invite scrutiny from both MCA and the Income Tax Department

MSME Form 1 and Annual Compliance Calendar

MSME Form 1 does not exist in isolation. It is one piece of a company's overall compliance framework. Here is how it fits into the annual compliance calendar for a typical Private Limited Company in 2026.

Notice that October is particularly heavy - MSME Form 1, ROC annual filing, and income tax returns for audit cases all fall in the same month. Companies that leave compliance to the last week face filing bottlenecks, DSC availability issues, and rushed data preparation. The solution? Start MSME Form 1 preparation in the first week of the month, well before the deadline.

Benefits of MSME Registration for Suppliers

While this guide focuses on the filing obligation for companies making payments, it is equally important for MSME suppliers to understand the protections available to them. If your business qualifies as a Micro or Small Enterprise, MSME Registration (Udyam Registration) unlocks several payment protection mechanisms. Understanding these benefits also helps buying companies appreciate why the 45-day rule and MSME Form 1 exist in the first place.

Payment Protection Under MSMED Act

Registered MSMEs are entitled to receive payment within 45 days. If a buyer delays beyond this period, the supplier can claim compound interest at three times the RBI bank rate. The buyer cannot contest the interest liability - it is automatic under the statute. This is a powerful financial incentive for buyers to prioritize MSME payments.

Access to MSME Samadhaan

Registered MSMEs can file delayed payment complaints on the MSME Samadhaan portal (samadhaan.msme.gov.in). The Micro and Small Enterprises Facilitation Council in each state reviews complaints and can order payment with interest. The process is faster and less expensive than civil litigation. Over 1.5 lakh cases have been filed, with recoveries running into thousands of crores.

Other Benefits of MSME Registration

• Priority sector lending from banks at lower interest rates
• Collateral-free loans under the Credit Guarantee Fund Scheme
• Preference in government procurement (25% mandatory procurement target)
• Subsidies on patent and trademark registration
• Reimbursement of ISO certification expenses
• Protection against delayed payments with statutory interest

If you run a small business and have not yet registered, the process is free and entirely online through the Udyam Registration portal. All you need is your Aadhaar number, PAN, and business details. The certificate is issued instantly.

Additional Practical Questions

Beyond the FAQs listed at the top, here are additional practical questions that companies encounter during MSME Form 1 preparation.

Can a company file a nil MSME Form 1?

There is no requirement to file a nil return. If your company has no outstanding payments to MSME suppliers beyond 45 days, you simply do not file. However, maintaining a board resolution or internal memo documenting this conclusion is recommended. This protects the company during statutory audits where the auditor specifically checks MSME payment compliance under CARO 2020 reporting requirements.

What if the supplier is registered as MSME but has not disclosed it to us?

The legal obligation to pay within 45 days applies regardless of whether the supplier has disclosed their MSME status to you. However, for MSME Form 1 filing purposes, you report based on your knowledge of the supplier's status. This is why proactive vendor verification is critical. Include an MSME disclosure clause in your standard purchase terms and update your vendor database regularly.

Does MSME Form 1 data become public?

MSME Form 1 filings are submitted to the MCA and are accessible through the MCA portal. While individual filings are not prominently displayed, they form part of the company's compliance record. Credit rating agencies, banks, and potential investors conducting due diligence can access this information. A history of delayed MSME payments reflected in MSME-1 filings can impact your company's creditworthiness assessment.

Summary

MSME Form 1 (MSME-1) is a half-yearly compliance that every company with delayed payments to Micro and Small Enterprise suppliers must file on the MCA portal. The April 2026 filing, covering October 2025 to March 2026, is due by April 30, 2026. The 45-day payment rule under the MSMED Act, the compound interest at 19.5% on delayed payments, the ₹20,000+ penalty for non-filing, and the Section 43B(h) income tax disallowance create a four-way compliance framework that makes timely MSME payments a financial imperative. Verify your suppliers' Udyam Registration status, maintain an MSME vendor database, file MSME Form 1 on time, and align your income tax computations with your MSME-1 data. The cost of compliance is minimal - the cost of non-compliance is not.
