OPC vs Pvt Ltd: Annual Compliance, Registration Cost & Conversion Guide

What annual compliance does an OPC need to complete each year? An OPC must file Form AOC-4 (financial statements) within 180 days of the financial year end, Form MGT-7A (annual return) within 60 days of the date by which an AGM would otherwise be due (29 November), file ITR 6 with a mandatory statutory audit, hold one board meeting in each half of the calendar year if it has more than one director, and maintain statutory registers, even without an AGM requirement.

A One Person Company offers solo entrepreneurs the liability protection of a company structure with genuinely reduced compliance compared to a Private Limited Company. That reduction is real but not absolute. OPCs still carry mandatory ROC filings, corporate income tax obligations, and a statutory audit requirement that many founders discover only after incorporation.

If you have not incorporated yet, start with our step-by-step guide to OPC registration in India, which covers eligibility, the nominee requirement, DSC, DIN and SPICe+ filing.

This guide sets out every annual compliance obligation for an OPC in India for financial year 2025-26, with precise deadlines, penalty rates, and the rules for converting to a Private Limited Company.

What Is a One Person Company (OPC)?

A One Person Company is defined under Section 2(62) of the Companies Act, 2013 as a company with only one person as its member. Unlike a sole proprietorship, an OPC is a separate legal entity with limited liability, perpetual succession (through the nominee mechanism), and access to formal credit facilities.

Three structural requirements define an OPC at incorporation:

• Single shareholder: only one natural person, who must be an Indian citizen, whether resident in India or not
• Single director: can be the same individual as the shareholder
• Mandatory nominee: an individual who is an Indian citizen (resident or not) and who will take over the membership if the sole member dies or becomes incapacitated

The nominee does not hold any share in the OPC during the member's lifetime. Their role activates only on the member's death or incapacity. The nominee must be named at incorporation with consent in Form INC-3; a later change of nominee is intimated to the RoC in Form INC-4.

OPC vs Private Limited Company: Compliance Differences

The compliance gap between an OPC and a Pvt Ltd is narrower than most founders expect, but it is genuine. The most significant difference is the AGM exemption.

Section 122 of the Companies Act specifically exempts OPCs from holding an AGM. The sole member can pass resolutions by communicating decisions in writing, which are entered into the minutes book and signed. This removes the procedural overhead of notice periods, quorum requirements, and shareholder voting applicable to Pvt Ltd companies.

For a detailed look at Pvt Ltd compliance obligations, see our guide on ROC annual compliance for Private Limited companies.

Form AOC-4: Financial Statements

Form AOC-4 is the annual filing of financial statements with the Registrar of Companies. For an OPC, this includes the balance sheet, profit and loss account, auditor's report, and Board's report.

Due date: Within 180 days from the close of the financial year.

For a company with FY ending March 31, 2026, the due date is September 27, 2026.

The Board's report for an OPC is an abridged version under Rule 8A of the Companies (Accounts) Rules, 2014. It covers items such as:

• The web address where the annual return is placed, if any
• The number of Board meetings held
• The Directors' Responsibility Statement
• Details of frauds reported by the auditor
• The Board's explanation on any qualification or adverse remark in the auditor's report
• Material changes and commitments affecting the company's financial position, and the state of the company's affairs

Form MGT-7A: Annual Return

Form MGT-7A is the simplified annual return format prescribed for OPCs and small companies. It replaced the full Form MGT-7 for these entities to reduce compliance burden.

Due date: Under Section 92(4), within 60 days from the date of the AGM or the date by which the AGM should have been held. An OPC holds no AGM, so the 60 days are counted from 30 September.

For FY ending March 31, 2026, the due date is November 29, 2026.

MGT-7A contains details of the company's registered office, principal business activities, shareholding pattern, and details of the sole member and director. Since an OPC has a single shareholder, the shareholding section is straightforward, but it must still be filed annually without exception.

Income Tax Compliance: ITR 6 and Statutory Audit

ITR 6 Filing

An OPC is treated as a company for income tax purposes and must file ITR 6. This is mandatory regardless of whether the OPC had any income during the year. A nil-income ITR 6 is still required.

Corporate tax rates applicable to an OPC:

• 22% base rate under Section 115BAA (after the 10% surcharge and 4% cess the effective rate is approximately 25.17%), available on opt-in basis, forfeits certain deductions
• 25% base rate under the regular regime for AY 2026-27 if total turnover or gross receipts in FY 2023-24 did not exceed Rs. 400 crore, plus applicable surcharge and 4% cess

Statutory Audit: No Turnover Threshold

This is the most important compliance distinction from a proprietorship. An OPC must get its accounts audited by a practicing Chartered Accountant regardless of turnover. The Section 44AB tax audit thresholds for businesses (Rs. 1 crore, or Rs. 10 crore where cash receipts and payments do not exceed 5%) do not remove the statutory audit requirement for an OPC.

The first auditor is appointed by the Board within 30 days of incorporation (Section 139(6)). The subsequent auditor is appointed for a term of five years under Section 139(1), by a resolution of the sole member in place of an AGM; annual ratification is no longer required since 7 May 2018. The OPC files Form ADT-1 for the appointment, and the auditor's report accompanies the AOC-4 filing.

Board Meetings and Resolutions for OPC

Under Section 173(5), an OPC with more than one director is deemed compliant if it holds at least one board meeting in each half of the calendar year, with a gap of not less than 90 days between the two meetings. This is a relaxation from the Pvt Ltd requirement of 4 meetings per year.

Where the OPC has only one director, Section 173 and Section 174 (quorum) do not apply. Under Section 122(4), any business that needs a Board resolution is entered in the minutes book and signed and dated by that director, and that date is treated as the date of the meeting.

Under Section 122, the sole member of an OPC can pass resolutions by communicating the decision in writing to the company. These written communications are entered in the minutes book and signed by the sole member. This mechanism covers ordinary and special resolutions that would otherwise require a general meeting.

OPC Nominee: Who, How, and What Happens

Every OPC must have a nominee designated at the time of incorporation. The nominee must be:

• An individual (not a body corporate)
• An Indian citizen, whether resident in India or not
• Not a minor

The nominee's written consent is recorded in Form INC-3 and submitted with the incorporation documents. If the nominee changes, the new nominee's consent is taken in Form INC-3 and the change is intimated to the RoC in Form INC-4.

On the death or permanent incapacity of the sole member, the nominee automatically becomes the member of the OPC. The nominee then has the option to either continue the OPC or convert it into a Pvt Ltd or a public company.

The nominee has no rights over the OPC or its assets during the member's lifetime.

Conversion to Private Limited: No Longer Mandatory

The old rule that forced an OPC to convert once its paid-up capital exceeded Rs. 50 lakh or its turnover exceeded Rs. 2 crore was removed by the Companies (Incorporation) Amendment Rules, 2021, with effect from 1 April 2021. An OPC can now grow without any capital or turnover cap.

An OPC can convert voluntarily into a Private Limited Company or a public company at any time, under Section 18 read with Rule 6 of the Companies (Incorporation) Rules, 2014. The conversion involves passing a special resolution, filing Form INC-6, and meeting the minimum requirements for the target company type (minimum 2 shareholders and 2 directors for a Pvt Ltd).

If you need guidance on the conversion process, our team at Tax Garden Support can walk you through the Form INC-6 procedure.

Penalties for Late Annual Compliance

Late filings attract additional fees that compound quickly:

• Form AOC-4 and Form MGT-7A: Rs. 100 per day per form from the due date, with no upper cap

On a practical basis, a 90-day delay on both AOC-4 and MGT-7A accumulates Rs. 18,000 in additional government fees alone, before any professional costs. The MCA21 portal does not accept nil-penalty late filings, the additional fee is calculated automatically at the time of submission.

Frequently Asked Questions

Does an OPC need a statutory audit if its turnover is very small?

Yes. An OPC is a company under the Companies Act, 2013, so its financial statements must be audited by a practising Chartered Accountant every year regardless of turnover or profit. The turnover limits of Section 44AB that let small proprietors skip a tax audit do not help an OPC. The audited accounts and auditor's report are then filed with the ROC in Form AOC-4.

Does a One Person Company have to hold an Annual General Meeting?

No. Section 122 of the Companies Act, 2013 exempts an OPC from holding an AGM. Decisions that would normally need a general meeting are passed by the sole member communicating the resolution in writing to the company, which is then entered in the minutes book and signed. The annual ROC filings in Form AOC-4 and Form MGT-7A are still mandatory every year.

Is an OPC still forced to convert into a private limited company once it crosses Rs 50 lakh capital?

No. The Companies (Incorporation) Amendment Rules, 2021, effective 1 April 2021, removed the rule that forced an OPC to convert once paid-up capital crossed Rs 50 lakh or turnover crossed Rs 2 crore. An OPC can now grow without a size cap and can convert voluntarily into a private or public company at any time by passing a special resolution and filing Form INC-6.

Does an OPC have to file ITR-6 if it earned nothing during the year?

Yes. Every company, including an OPC, must file its income tax return in ITR-6 even when it has nil income or a loss. Because company accounts are audited, the due date for AY 2026-27 is 21 November 2026, with the tax audit report (where applicable) due by 21 October 2026 (both extended by CBDT Circular 07/2026 dated 28 September 2026 from 31 October and 30 September). Filing on time also lets the OPC carry forward business losses to later years.

What tax rate does an OPC pay on its profits?

An OPC is taxed like any domestic company. It pays 25% if its turnover in the relevant earlier year did not exceed Rs 400 crore, plus applicable surcharge and 4% cess. Alternatively it can opt for Section 115BAA at 22%, which works out to about 25.17% after the 10% surcharge and cess, but it then gives up most deductions and incentives.

What is the penalty for filing Form AOC-4 or MGT-7A late?

Late ROC filings attract an additional fee of Rs 100 per day for each form from the due date, with no upper cap. The fee is calculated automatically by the MCA portal when the form is submitted. A delay of 90 days on both AOC-4 and MGT-7A therefore adds about Rs 18,000 in government fees alone, before any penalty proceedings for continuing default.
