Turning a private company public is a clean, RD-free process — a special resolution and two forms. Going back the other way is far heavier, because shrinking public protections means the Regional Director and your creditors get a say.

The asymmetry: private → public needs no RD approval; public → private does.

A growing private company preparing for institutional fundraising or an IPO needs to become a public company first. Under Section 18 that's a contained, four-to-eight-week process: line up seven shareholders and three directors, adopt new articles, pass a special resolution, file two forms, collect a fresh Certificate of Incorporation. But a public company wanting to go private — to cut compliance and regain control — faces a materially tougher path, because reducing the public's protections triggers Regional Director approval and a creditor-notice process. Same section, two very different journeys.

BOTTOM LINE

  • Private → public: ≥7 shareholders, ≥3 directors; special resolution → MGT-14 (30 days) → INC-27 (15 days) → fresh COI. No RD approval.
  • Public → private: special resolution → MGT-14 → Regional Director approval (RD-1) + creditor notice → INC-28 → INC-27.
  • Either way: alter the MOA (name clause) and AOA; not available while under investigation, inspection, prosecution, or in default.

What Section 18 covers

Governs this section: Section 18 (read with Sections 13 & 14 and Rule 33, Companies (Incorporation) Rules, 2014)

Section 18 governs the conversion of an already-registered company from one class to another — private to public and vice versa (and OPC, unlimited, Section 8 conversions). It works through Section 13 (alter the MOA) and Section 14 (alter the AOA): you change the company's constitution to fit the new class, and the ROC issues a fresh Certificate of Incorporation. Pre-existing liabilities survive the conversion unchanged.

Private to public — the process

Governs this section: Section 18 & Rule 33

  1. Confirm the structural minimums: at least 7 shareholders and 3 directors, and adopt a new AOA that removes the Section 2(68) private-company restrictions (the share-transfer restriction, the cap on members, the bar on public invitations).
  2. Board meeting → call EGM.
  3. EGM: special resolution altering the MOA (name from "Private Limited" to "Limited") and AOA.
  4. File MGT-14 within 30 days of the resolution.
  5. File INC-27 (application for conversion) within 15 days of the resolution — but after MGT-14, since INC-27 needs the MGT-14 SRN.
  6. The ROC issues a fresh Certificate of Incorporation with the new name (dropping "Private").

No Regional Director approval is needed. Typical timeline: four to eight weeks.

Public to private — and why it's harder

Governs this section: Section 14, Section 18 & Rule 41, Companies (Incorporation) Rules, 2014

THE EXTRA LAYER

Going private reduces the protections that public status gives creditors and the market, so the law adds a gate: Regional Director (Central Government) approval. The flow: special resolution → MGT-14 → application to the RD in Form RD-1 (within 60 days of the resolution) → newspaper advertisement and individual notice to creditors/debenture holders inviting objections → RD order → INC-28 to file the order → INC-27 to effect the conversion. The name re-acquires "Private," and the AOA re-adopts the Section 2(68) restrictions.

When you can't convert

Governs this section: Section 18 & Rule 33/41

Conversion is blocked if the company is under investigation, inspection or prosecution, or is in default on its statutory filings (annual return / financial statements), deposits, or debenture/interest repayments. Clear those before applying — an open default or proceeding will stop the conversion at the Registrar or the RD.

Life after conversion to public

Governs this section: Sections 149, 177, 178 (as applicable)

Becoming public brings heavier governance. Depending on thresholds, the company may need independent directors (Section 149), an audit committee (Section 177) and a nomination and remuneration committee (Section 178); shares become freely transferable; disclosures tighten; and if it later lists, the full SEBI regime applies. The flip side of public status — access to public capital — comes bundled with that compliance load, so plan the governance build-out alongside the conversion.

Common mistakes

  1. Filing INC-27 before MGT-14. INC-27 needs the MGT-14 SRN, so MGT-14 goes first.
  2. Missing the structural minimums. Private → public needs 7 shareholders and 3 directors before you file.
  3. Reusing the old private AOA. Adopt a fresh AOA that drops (or, going private, adds) the Section 2(68) restrictions.
  4. Attempting to go private without RD approval. Public → private needs RD-1 and creditor notice.
  5. Converting while in default or under investigation. It will be blocked — clear it first.

Checklist

  1. Decide the direction and confirm eligibility (no default / investigation; structural minimums for public).
  2. Adopt the appropriate new AOA; board resolution → EGM special resolution altering MOA + AOA.
  3. File MGT-14 within 30 days.
  4. Private → public: file INC-27 within 15 days (after MGT-14) → fresh COI.
  5. Public → private: file RD-1, advertise, notify creditors → RD order → INC-28 → INC-27.
  6. Update name everywhere and build out the governance a public company requires.

FAQ

What does converting a private company to public require? At least 7 shareholders and 3 directors, a special resolution, MGT-14 within 30 days, INC-27 within 15 days, and a fresh Certificate of Incorporation. No RD approval.

Is public-to-private conversion harder? Yes — it needs Regional Director approval (Form RD-1), a newspaper advertisement, and individual creditor notice, on top of the special resolution and filings.

Which forms are used? MGT-14 (the resolution) and INC-27 (the conversion application); public → private also uses RD-1 and INC-28.

Can a company convert while in default? No. Conversion is barred while the company is under investigation/inspection/prosecution or in default on filings, deposits or debentures.

What changes after going public? Free share transfer, tighter disclosures, and — depending on thresholds — independent directors and board committees; SEBI rules apply if it lists.
