IPO Investing in India: Allotment, Listing Gains & Taxation Explained

How the IPO Application Process Works

Retail investors apply for IPOs through their broker's app or net banking, using the ASBA (Application Supported by Blocked Amount) facility — the application amount is blocked in your bank account (not debited) until allotment is finalised. Key elements of the application:

• Lot Size: IPOs are sold in fixed "lots" (a minimum number of shares), and you can apply for one lot or multiples, up to the retail category limit.
• Price Band: IPOs are typically issued with a price band (e.g., ₹100-₹105); the final issue price is determined after the subscription period closes, usually at or near the upper end for oversubscribed issues.
• Subscription Period: Usually open for 3 working days, during which the issue may get subscribed multiple times over (oversubscription) in various categories — retail, non-institutional, and qualified institutional buyers (QIB).

How Allotment Works (and Why It's Not Guaranteed)

If the retail category is not oversubscribed, all valid applicants typically receive at least one lot. If it is oversubscribed — common for popular IPOs — allotment in the retail category is generally done via a computerised lottery, since most retail applicants apply for similar lot sizes, making proportionate allotment impractical. This means:

• Submitting a large application amount does not improve your odds beyond the number of lots it represents — the lottery is typically per-applicant, not proportional to amount.
• Many applicants in heavily oversubscribed retail categories receive zero allotment.
• If you're not allotted shares, the blocked amount is released back to your account (typically within a few working days of allotment finalisation) — no shares means no debit.

What Happens on Listing Day

On the listing date, the shares begin trading on the stock exchange, and the opening price is determined by market demand/supply at that moment — it can open at a premium (above issue price), at par, or at a discount (below issue price). Listing gains are not guaranteed: while strong IPOs have historically listed at significant premiums, weaker or overpriced issues have listed flat or below issue price, resulting in immediate notional or realised losses for investors who bought at issue price.

How IPO Shares Are Taxed When Sold

Once allotted, IPO shares are taxed exactly like any other listed equity shares based on holding period from the date of allotment:

• Sold within 12 months (including on listing day): Short-term capital gains under Section 111A.
• Held for more than 12 months: Long-term capital gains under Section 112A, subject to the applicable annual exemption threshold.

See our capital gains tax guide for current rates and exemption limits. The gain (or loss) is computed as the difference between the sale price and the IPO issue price (your cost of acquisition).

A Balanced Approach to IPO Investing

IPO applications require no ongoing capital commitment beyond the blocked amount during the subscription window, making them relatively low-friction to apply for — but allotment is uncertain, and listing performance is unpredictable. For investors building a long-term portfolio (see our getting started guide), IPO applications can be a small, optional part of a strategy, but shouldn't be relied upon as a primary investment approach given the allotment lottery and listing-day uncertainty.
