Conversion of Private Company into Public Company in India: Procedure, Forms & Timeline
The conversion of a private company into a public company in India is governed by Section 18 of the Companies Act, 2013. The process requires the company to have at least 7 shareholders and 3 directors, pass a special resolution (75%+ shareholder approval), alter the Memorandum (MoA) and Articles (AoA) of Association, file Form MGT-14 within 30 days and Form INC-27 within 15 days with the Registrar of Companies (ROC), and obtain a fresh Certificate of Incorporation reflecting the new public company status. The complete procedure typically takes 4–8 weeks.
Converting from private to public unlocks the ability to raise capital from the public through equity issuance, IPOs, and listed instruments, making it the standard path for private limited companies ready for institutional fundraising, IPO, or large-scale expansion. However, it also brings stricter governance under the Companies Act, 2013, mandatory disclosures, and (if listed) SEBI compliance.
This 2026 guide walks through the complete procedure for conversion of a private company into a public company; eligibility, documents required, step-by-step ROC filings, post-conversion compliance, costs, timelines, common challenges, and a comparison of all conversion types under Section 18.

What is Section 18 of the Companies Act, 2013?
Section 18 of the Companies Act, 2013, governs all class-to-class conversions of registered companies, private to public, public to private, OPC to private/public, unlimited to limited, and Section 8 conversions. It works in conjunction with Section 13 (alteration of MoA), Section 14 (alteration of AoA), and Rule 33 of the Companies (Incorporation) Rules, 2014, to provide the complete legal framework. Once the MoA is altered and ROC issues the fresh Certificate of Incorporation, the company legally operates as a public entity with full rights to transfer shares freely, issue prospectuses, and raise capital from the public.
Section 18 of the Companies Act, 2013:
- Allows a private company to alter its MoA to reflect public company status.
- Requires approval from the board of directors and shareholders through formal resolutions.
- Protects pre-existing liabilities like debts and obligations incurred before conversion, which remain enforceable.
- Mandates filing forms and documents with the ROC.
- Ensures the company meets all regulatory requirements before conversion.
- Protects shareholder interests through a structured legal process.
- Serves as a roadmap for raising capital, gaining credibility, and expanding the business.

Eligibility Criteria for a Private Company to Convert into a Public Company
There are differences between public and private companies in India. Not every private company can convert into a public company. The law sets rules to ensure a company is ready for the added responsibilities. Meeting these requirements keeps the transition smooth and compliant.
Key eligibility requirements:
- Must be a private company registered under the Companies Act, 2013.
- Needs at least 7 shareholders and 3 directors. If there are fewer than seven members, the company must increase membership.
- Cannot have ongoing legal disputes that block the conversion process.
- Must comply with all provisions of the existing Memorandum of Association (MOA) and Articles of Association (AOA).
- Cannot have restrictions on share transfer that conflict with public company rules.
- Must clear all statutory dues, including taxes and employee contributions.
- Should have a clean record of filing annual returns and financial statements with the ROC.
- Existing loans and outstanding borrowings must follow public company rules.
- The company must not have a record of major legal violations.
Following these criteria ensures your company can legally convert, raise capital, and expand its operations confidently.
Rules for Conversion of a Private and Public Company
Converting a private company into a public company, or vice versa, requires following specific rules and statutory provisions, including:
- Companies (Incorporation) Rules, 2014: Rule 33 and related provisions govern the conversion process. These rules outline procedural requirements for filing applications, resolutions, and other necessary documents with the RoC. Additional rules like Rule 7, 37, and 39 apply to OPCs, unlimited companies, and guarantee companies.
- Alteration of MoA: Section 13 of the Companies Act, 2013, requires companies to alter their MoA during conversion. The MoA must reflect the company’s new status and objectives.
- Alteration of AoA: Section 14 of the Companies Act mandates changes to the AoA to align with public or private company regulations. These changes include governance rules, quorum requirements, and share transfer provisions. Adopting a fresh AoA is recommended to fully comply with public company norms.
- Role of the Registrar of Companies (ROC): The ROC reviews the application, scrutinizes the filed documents, and approves the conversion. After verification, the ROC issues a new Certificate of Incorporation, officially changing the company’s status.
By following these rules carefully, the company ensures a legally valid conversion and avoids delays or rejection.
How to Convert a Private Limited Company into a Public Limited Company?
Converting a private company into a public company requires following a structured legal process:
Step 1: Conduct a Board Meeting and Pass the Board Resolution
The board meeting is the first formal step in the conversion process. Under Section 173 of the Companies Act, 2013 and Secretarial Standard SS-1, the board meeting requires at least 7 days’ prior notice in writing to all directors.
- Send Notice: Issue board meeting notice at least 7 days in advance via post / email, complying with Section 173 and SS-1.
- Quorum: A minimum of 1/3 of the total directors or 2 directors (whichever is higher) must be present.
- Pass the Board Resolution approving:
- The proposal to convert the private company into a public company
- Alteration of the Memorandum of Association (MoA) and Articles of Association (AoA)
- The date, time, and venue of the Extraordinary General Meeting (EGM) of shareholders
- Authorising directors to file the necessary forms with the Registrar of Companies (ROC)
This ensures that the company’s leadership is aligned and officially approves the move.
Step 2: Hold the EGM and Pass the Special Resolution
Convene an Extraordinary General Meeting (EGM) of shareholders to obtain approval for the conversion through a special resolution under Section 114(2) of the Companies Act, 2013.
- Notice Period: Send the EGM notice with explanatory statement to all members, directors, and auditors at least 21 clear days in advance (or shorter notice with consent of 95%+ shareholders).
- Quorum: Minimum 2 members personally present (for companies with up to 1,000 members).
- Special Resolution Threshold: At least 75% of votes cast must be in favour of the conversion (Section 114(2)).
- Resolutions to Pass: (a) Conversion of the private company into a public company under Section 18, (b) Alteration of the MoA (removing private company restrictions), and (c) Alteration of the AoA (adopting public company-compliant articles).
Step 3: File ROC Forms (MGT-14 + INC-27)
File the following forms with the Registrar of Companies (ROC) on the MCA V3 portal:
| Form | Purpose | Deadline | Fee |
|---|---|---|---|
| Within 30 days of the ROC’s approval order | Filing the special resolution | Within 30 days of passing the SR | Based on share capital |
| Form INC-27 | Application for conversion | Within 15 days of passing the SR | Based on authorised capital |
| Form INC-28 | Intimation of ROC order | Within 30 days of the ROC’s approval order | ₹0 (intimation form) |
Mandatory Attachments to Form INC-27:
- Certified copy of the Board Resolution approving the conversion
- Certified copy of the Special Resolution passed at the EGM
- Altered MoA reflecting public company status
- Altered AoA with public company-compliant clauses
- Notice of EGM with explanatory statement
- Minutes of the EGM
- Director declarations confirming legal compliance
- NOC from secured creditors / debenture holders (if applicable)
Pro tip: Stamp duty on the altered MoA and AoA is state-specific and must be paid before filing.
Step 4: Obtaining the New Certificate of Incorporation
After verifying the documents, the ROC approves the conversion:
- The ROC cancels the old registration and issues a new Certificate of Incorporation (CoI), reflecting the public company status. The company officially becomes “public” only after this certificate is issued.
- This certificate legally establishes the company as a public entity, enabling it to raise capital and operate under public company regulations.
Step 5: Completing Post-Conversion Formalities
After ROC approval, the company must update records and adopt new rules to ensure smooth operations as a public company.
- Update Statutory Registrations: Revise PAN, bank accounts, letterhead, GST, TAN, and other statutory records.
- Adopt New MoA and AoA: Ensure these reflect public company requirements, including quorum rules, share transferability, and compliance obligations.
- Inform Stakeholders: Notify investors, lenders, and government authorities about the conversion.
- Update Contracts and Signatories: Revise agreements, company seals, and authorized signatories to align with the new public status.
Completing the detailed procedure for the conversion of a private company into a public company ensures a smooth transition for the business.
Disclaimer: Businesses should consult a company secretary or legal professional before initiating conversion, especially in cases involving foreign investment, pending litigation, or regulatory approvals.

- Manage Share Transferability and Investor Relations: Allow free transfer of shares. Communicate regularly with shareholders. Address grievances promptly.
- Protect Shareholder Rights: Ensure fair treatment of voting, exit, and pre-emptive rights. Inform shareholders about new share issuance or capital changes.
- Regulate Loans and Related-Party Transactions: Obtain approvals and disclose transactions under Section 188. Prevent conflicts of interest and maintain transparency.
- Comply with Secretarial Standards and Governance Codes: Maintain statutory registers and hold meetings as required. Follow the codes of conduct for directors and key managers.
- Adhere to SEBI Rules (if listed): File shareholding patterns, quarterly results, and other disclosures. Follow insider trading regulations and continuous disclosure obligations.
- Handle Regulatory Scrutiny and Legal Liability: Directors must act diligently to avoid penalties. Consider D&O insurance to reduce personal risk.
Following these rules ensures smooth operations, strengthens credibility, and builds investor confidence. It also lays a strong foundation for growth and capital raising.
