OPC Compliance Calendar October 2026: Important Filings & Requirements
Introduction
The OPC Compliance Calendar October 2026 highlights the key statutory obligations that One Person Companies should monitor during the month. October primarily includes compliance requirements related to financial statement filing through Form AOC-4 and MSME-1 reporting, wherever applicable.
Completing these filings requires accurate financial records, proper documentation, and verification of applicable requirements. Since every OPC may not have the same reporting obligations, compliance applicability depends on factors such as outstanding MSME dues, financial records, company status and applicable legal provisions.
Tracking these requirements helps OPCs maintain updated MCA records, avoid additional filing fees, and reduce the risk of compliance issues.
Quick Insights
- MSME Reporting: MSME-1 filing applies only to OPCs having outstanding dues to eligible Micro and Small Enterprise suppliers beyond the prescribed period.
- Financial Record Review: Proper verification of financial statements and supporting documents helps ensure accurate MCA filing.
- Applicability Check: Not every OPC is required to file MSME-1, making supplier and payment record verification important.
- Compliance Management: Timely completion of applicable filings helps OPCs avoid additional fees, penalties and regulatory follow-ups.

MSME-1 (Half-Yearly Return Filing) |
No separate late fee is specifically prescribed for MSME-1 filing. However, failure to furnish required information may attract penalties under the applicable provisions of the Companies Act, 2013. | Generally, no interest is applicable as MSME-1 is a reporting requirement and does not involve tax payment. |
Non-compliance may result in penalties for failure to provide required information and may affect the company’s statutory compliance record. |
Key Compliance Considerations:
- Additional filing fees and penalties are separate consequences and depend on the nature of non-compliance.
- Before filing MSME-1, companies should verify outstanding dues, supplier details and payment records to ensure accurate reporting.
- Timely completion of ROC filings helps companies avoid unnecessary compliance issues and regulatory follow-ups.

Frequently Asked Questions
1. Is AOC-4 filing applicable to an OPC if there is no business activity during the financial year?
Yes. An OPC is required to comply with applicable annual filing requirements even if it has limited or no business activity during the financial year, subject to the applicable provisions of the Companies Act, 2013. The OPC must ensure that required financial statements and statutory filings are completed as prescribed.
2. What documents are required for filing AOC-4 by an OPC?
An OPC is required to file its financial statements through the applicable AOC-4 form along with documents prescribed under MCA filing requirements. The applicable attachments may vary depending on the nature of the filing and company-specific requirements.
3. How is AOC-4 filing different for an OPC compared to other companies?
An OPC is required to file financial statements through AOC-4 like other companies; however, certain compliance provisions differ due to its single-member structure. For example, an OPC is not required to conduct an Annual General Meeting under the applicable provisions of the Companies Act, 2013.
4. Can an OPC file AOC-4 if the financial statements are not approved?
No. Financial statements should be prepared and approved as required under the Companies Act, 2013 before filing them with the Registrar of Companies. The OPC should maintain proper approval records and supporting documents before submission.
5. How should an OPC determine whether MSME-1 filing is applicable?
An OPC should verify whether it has outstanding payments due to eligible Micro and Small Enterprise suppliers beyond the prescribed period under the MSMED Act, 2006. MSME-1 applicability depends on the existence of such reportable outstanding dues and not merely on whether the OPC is registered as an MSME.
6. Can an OPC file MSME-1 if there are no outstanding dues to Micro and Small Enterprises?
Generally, MSME-1 reporting applies when an OPC has outstanding dues payable to eligible Micro and Small Enterprise suppliers beyond the prescribed period. If there are no such reportable outstanding dues, MSME-1 filing may not arise. The OPC should verify applicable requirements before filing.
7. What details should an OPC verify before filing MSME-1?
Before filing MSME-1, an OPC should verify supplier eligibility, MSME registration details (where available), outstanding invoice records, payment status and reasons for delayed payments to ensure accurate statutory reporting.
8. What records should an OPC maintain before completing October compliance filings?
An OPC should maintain updated financial statements, books of accounts, supplier payment records, MSME-related documents, approval records and other supporting documents required for accurate statutory reporting.
