Private vs Public Company in India: Key Differences Explained

By CA Madhusmita Padal • Updated September 2026 • 7 min read

The Companies Act 2013 defines two primary types of companies: Private Limited and Public Limited. While both are body corporates with separate legal identities and limited liability, they differ significantly in their ability to raise public capital, share transfer rights, compliance obligations, and governance requirements. This guide maps every material difference — so founders and legal advisors can choose the right structure upfront or plan an informed conversion.

Key Takeaways

  • Private companies: max 200 members, restricted share transfer, cannot issue public shares.
  • Public companies: no maximum members, free share transfer, can do IPO.
  • Minimum directors: 2 (private) vs 3 (public).
  • Public companies face significantly higher compliance including SEBI regulations if listed.
  • A Private Limited Company can convert to Public by passing a Special Resolution (Form INC-27).

What is the complete comparison between Private and Public companies?

Parameter Private Limited Company Public Limited Company
Governing section Section 2(68), Companies Act 2013 Section 2(71), Companies Act 2013
Minimum members 2 7
Maximum members 200 No limit
Minimum directors 2 3
Share transfer Restricted (board approval needed) Free (listed: via stock exchange)
Public issue / IPO Not allowed Allowed (with SEBI approval if listing)
Min. paid-up capital None (₹1 minimum) ₹5 lakh
Name suffix Must end with “Private Limited” Must end with “Limited”
Annual General Meeting Exempt from AGM requirement (first 2 years) Mandatory AGM within 6 months of FY end
Prospectus requirement Not applicable Required for public issues
SEBI regulations Not applicable (unlisted) Applies if listed (LODR regulations)
Typical use case Startups, SMEs, family businesses, subsidiaries Large businesses planning IPO or public capital

How does share transferability differ between private and public companies?

This is one of the most important distinctions for investors and founders:

  • Private company: The Articles of Association must restrict share transfers. Common restrictions include: right of first refusal by existing shareholders, board approval requirement, and a pre-emption clause. Early employees holding ESOPs cannot sell on the open market
  • Public unlisted company: Shares can be freely transferred among parties without board approval, but there is no exchange-based liquidity
  • Public listed company: Shares trade on BSE or NSE. Shareholders can buy or sell at market prices through their demat account during trading hours

How do private and public companies differ in raising capital?

Capital Source Private Company Public Company
Angel/VC investment Yes Yes
IPO (Initial Public Offering) No Yes (with SEBI DRHP filing)
FPO / Rights issue to public No Yes
Private placement Yes (max 200 persons) Yes
Non-convertible debentures to public No Yes

What are the compliance differences for private vs public companies?

  • Annual Return (MGT-7A): Small private companies file MGT-7A (simplified); public companies file the full MGT-7 with additional disclosures
  • AGM: Private companies have a relaxed AGM regime (exempted from several provisions for first 2 years); public companies must hold AGM within 6 months of financial year end
  • Statutory Auditor: Both must have a statutory auditor. Public companies cannot have the same auditor firm for more than 10 years without rotation
  • SEBI compliance (if listed): Quarterly financial reporting, Corporate Governance Report, Insider Trading restrictions, and Listing Agreement compliance
  • Secretarial audit: Mandatory for public companies with paid-up capital ≥ ₹50 crore or turnover ≥ ₹250 crore
Cost implication: Compliance for a listed public company can cost ₹20–₹50 lakh/year or more, compared to ₹35,000–₹1,20,000 for a small Private Limited Company. This compliance cost is often a reason to remain private longer.

What is the difference between a listed and unlisted public company?

All listed companies are public companies, but not all public companies are listed:

  • Unlisted public company: Has the public company structure (min 7 members, free share transfer, “Limited” name suffix) but shares are not traded on any stock exchange. Less regulated than listed companies
  • Listed public company: Shares are listed on BSE/NSE. Subject to full SEBI LODR compliance, quarterly reporting, independent directors on board, Audit Committee, Nomination and Remuneration Committee

How can a Private Limited Company convert to a Public Limited Company?

  1. Pass a Special Resolution at an EGM to convert to a public company and amend MOA/AOA
  2. Ensure the company meets minimum public company requirements (3 directors, 7 members, ₹5 lakh paid-up capital)
  3. File Form INC-27 with MCA along with the amended MOA, AOA, and Special Resolution
  4. ROC issues a fresh Certificate of Incorporation showing the changed status
  5. Remove “Private” from the company name in all records, signs, and registrations
IPO planning: Companies planning an IPO typically convert to public company status 12–24 months before the planned listing, to build the public company compliance track record that SEBI DRHP filings require.
