Introduction
When a private company decides to raise capital from public investors, it launches an Initial Public Offering. India’s IPO pipeline for 2026 is expected to be one of the largest ever, with over 190 companies likely to raise more than ₹2.5 lakh crore, making it crucial for retail investors to understand how this process works.
An IPO transforms a privately-held company into a publicly-traded entity, allowing ordinary investors to own shares that were previously available only to founders, venture capitalists, or private equity firms. The process is comprehensively regulated by SEBI under the Issue of Capital and Disclosure Requirements (ICDR) Regulations, 2018.
What is an Initial Public Offering?
An Initial Public Offering (IPO) is the first sale of stock by a private company to public investors. Under SEBI regulations, companies use IPOs to raise capital for expansion, debt repayment, or other business needs, whilst providing early investors with an exit opportunity.
The IPO’s meaning extends beyond just listing shares. It represents a company’s transition from private ownership to public accountability. Companies must meet stringent disclosure requirements, financial audits, and ongoing compliance obligations once publicly listed on NSE or BSE.
For investors, IPOs offer the chance to invest in companies at their public market debut, though success depends on understanding the application process, pricing mechanisms, and allocation methods.
How Does an IPO Work in India?
The IPO process typically spans 3-4 months from initial filing to listing:
- Draft Red Herring Prospectus (DRHP) Filing: The company submits detailed financials and business plans to SEBI for review
- Roadshows and Marketing: Management presents to institutional investors to gauge demand
- Price Discovery: Based on investor feedback, the company finalises the price band for book-building IPOs
- Subscription Period: Open for 3 working days, during which investors submit applications
- Allotment: Shares allocated based on subscription levels and investor categories
- Listing: Shares begin trading within 3 working days of IPO closure
Key regulatory safeguard: SEBI mandates a minimum 90% subscription for proceeding with allotment. Below this threshold, the company must refund all application money.
Investor Categories:
- Retail (up to ₹2 lakh): Minimum 35% reservation
- High Net-worth Individuals (above ₹2 lakh): 15% allocation
- Qualified Institutional Buyers: 50% allocation
Types of IPOs in India
Book Building vs. Fixed Price
| Feature | Book Building | Fixed Price |
| Price Discovery | Demand-based within price band (e.g., ₹100-110) | Predetermined single price |
| Flexibility | Investors bid at different price points | Single application price |
| Timeline | Takes longer due to demand assessment | Faster allotment process |
| Market Preference | 90% of Indian IPOs use this method | Rarely used now |
Mainboard vs. SME IPO
| Aspect | Mainboard IPO | SME IPO |
| Minimum Issue Size | Post-issue paid-up capital of at least ₹10 crore | ₹1 crore minimum |
| Listing Platform | NSE/BSE main exchanges | NSE Emerge/BSE SME platforms |
| Compliance | Stringent reporting requirements | Relaxed disclosure norms |
| Investor Access | Open to all investors | Some restrictions apply |
How to Apply for an IPO
Mandatory Requirements (per SEBI guidelines):
- Active demat account with completed KYC
- PAN card
- Bank account linked with UPI
Application Process:
Since January 2019, retail investors have been able to apply through UPI for applications up to ₹5 lakh. Funds are blocked (not debited) until allotment, improving transparency over the older ASBA system.
Investment Limits:
- Retail investors: Up to ₹2 lakh per IPO
- Minimum application: Lot size multiples
Applications without proper demat, PAN, or UPI linkage are rejected at the bidding stage.
Tax Implications on IPO Shares
For FY 2024-25 (effective July 23, 2024), IPO share gains are taxed based on holding period:
- Short-term Capital Gains (holding <12 months): 20% tax under Section 111A, an increase from the previous 15% rate following Budget 2024.
- Long-term Capital Gains (holding ≥12 months): 12.5% tax on gains exceeding ₹1.25 lakh annual exemption under Section 112A, without indexation benefit.
Example: If you sell IPO shares for ₹2 lakh profit after 14 months, tax applies only on ₹75,000 (₹2 lakh minus ₹1.25 lakh exemption) at 12.5%, resulting in ₹9,375 tax liability.
Consult a tax advisor for your specific situation.
Understanding Your IPO Investment Journey
Participating in IPOs offers access to companies at their public market debut, but conviction comes from understanding the regulatory framework, application mechanics, and post-listing implications. With SEBI’s investor-friendly reforms like UPI applications and mandatory disclosure requirements, retail investors now have clearer pathways to participate in India’s growing public equity market.
Remember: IPO allotment isn’t guaranteed, especially in oversubscribed issues. Focus on understanding the company’s fundamentals rather than listing day gains alone.
FAQs
The minimum investment depends on the lot size and issue price set by the company. For example, if the lot size is 15 shares and the issue price is ₹900 per share, the minimum investment would be ₹13,500. Retail investors can apply for shares worth up to ₹2 lakh per IPO under the retail investor category.
Retail investors receive proportionate allotment. In heavily oversubscribed IPOs, a lottery system ensures that maximum applicants get at least one lot before remaining shares are distributed proportionately among winners.
Yes. Shares credited to your demat account on the listing day can be sold immediately through the stock exchanges. There’s no lock-in period for retail investors, unlike promoters or anchor investors.
If the subscription falls below 90%, SEBI regulations require the company to refund all application money. The IPO cannot proceed to listing, protecting investor interests from a weak market reception.
Check on the registrar’s website (Link Intime or KFin Technologies) using your PAN or application number. Alternatively, visit the BSE or NSE allotment portals for status updates once allotment is finalised.
Yes. Gains are taxed at 20% (STCG) if sold within 12 months, or 12.5% (LTCG) on gains above ₹1.25 lakh if sold after 12 months, as per FY 2024-25 rates.
