When you apply for an IPO and the allotment goes against you, one question follows fast: where is my money? The good news is that your cash was never actually paid out. Under the ASBA system, your application amount is only blocked in your own bank account, and the IPO refund and unblocking timeline runs on a fixed SEBI clock. Since the market moved to a T+3 listing cycle, allotment is settled a day after the issue closes and un-allotted money is released well before the shares list. This guide walks the full money trail from the day you apply to the day your funds are free again — and what to do if they are not.
Your IPO money is blocked, not paid — what ASBA really does
ASBA stands for Application Supported by Blocked Amount. It is the only route a retail investor can use to apply for a mainboard IPO in India, and it changes how you should think about your money.
When you place an IPO bid, your bank does not transfer the application amount to the company. Instead, it puts a hold, or lien, on exactly that amount inside your own savings account. The money stays with you. It still shows in your balance, but you cannot spend or withdraw the blocked portion while the bid is live.
If you applied through UPI, the same thing happens in a slightly different wrapper: you approve a UPI mandate, and your bank blocks the funds against that mandate until the IPO process finishes. Nothing leaves your account unless shares are actually allotted to you.
This design protects you. You keep earning savings interest on the blocked amount, and there is no separate "refund cheque" to wait for if you miss out — because no payment was ever made.
It is worth remembering why this matters. Before ASBA became the standard, applicants paid the full amount upfront and then waited, sometimes for weeks, for a physical refund if they were not allotted shares. Money sat idle with the company or the banker, lost to the investor the whole time. ASBA flipped that: your capital never leaves your control, so there is nothing to recover and nothing to lose track of. If you want this foundation built properly rather than pieced together from scattered videos, a structured stock market training course walks you through the primary market end to end. We covered the application side in detail in our guide to applying for an IPO with UPI and ASBA.
The IPO refund and unblocking timeline: from T to T+3
SEBI cut the IPO listing cycle from T+6 to T+3, where T is the day the issue closes for subscription. It was voluntary for issues opening on or after 1 September 2023 and became mandatory for every issue opening on or after 1 December 2023. The whole money trail now fits inside three working days.
Your money moves on a fixed three-day clock
T+1 — the basis of allotment is finalised
The day after the issue closes, the registrar reconciles every valid bid, removes technical rejections, and runs the lottery or proportionate split. The basis of allotment is finalised before 6 PM on T+1, and the stock exchange approves it the same evening. At this point the system knows exactly who got shares and who did not.
T+2 — unblocking of un-allotted funds and credit of shares
This is the day your money status changes. From the morning of T+2, debit and unblock instructions go out to banks. For investors who were not allotted shares, the un-allotted amount is unblocked by about 4 PM on T+2. For those who got a partial allotment, only the allotted value is debited and the rest is released. Allotted shares are credited to demat accounts the same afternoon.
T+3 — listing and trading begin
On the third working day after the issue closes, the share lists and trading opens. By the time you can buy or sell the stock, your refund question is already settled — because any money owed back to you was released a full day earlier, on T+2. If you only ever check your account on listing day, this is why the block has usually already vanished.
Allotted, partly allotted, or not allotted — what happens to your money
Your outcome falls into one of three buckets, and the money behaves differently in each. The table below is the quickest way to see where you stand.
| Outcome | What happens to the blocked amount | By when |
|---|---|---|
| Full allotment | The entire application amount is debited; shares are credited to your demat account. | T+2 |
| Partial allotment | Only the value of shares allotted is debited; the remaining blocked amount is unblocked. | T+2 |
| No allotment | Nothing is debited; the full blocked amount is released back to free balance. | T+2 |
Notice the pattern: you are only ever charged for shares you actually receive. In a heavily oversubscribed issue, most retail applicants land in the "no allotment" row, which is why understanding the release timeline matters more than the refund itself. To see why so many bids get nothing, read our explainer on how the basis of allotment works when an IPO is oversubscribed.

There is no literal refund transaction in an IPO, but the way your hold is lifted depends on how you applied.
If you applied through UPI (the common route for retail bids up to ₹5 lakh), your bank blocked the money against a UPI mandate you approved on your phone. When the allotment is done, the sponsor bank revokes that mandate. The hold drops off and the amount simply rejoins your spendable balance. You may notice the mandate disappear from your UPI app before the balance updates — that is normal.
If you applied through a bank branch or net-banking ASBA form, your bank acted as a Self Certified Syndicate Bank and placed the lien directly. On instruction from the registrar, it lifts the lien on the un-allotted portion. Either way, the money was always in your account; the bank is only removing a restriction, not sending you cash.
One practical note: a few banks process the release in a nightly batch rather than in real time, so the free balance can reflect a few hours after the official T+2 deadline. That is a bank processing lag, not a lost refund.
What if your money stays blocked after T+3?
Occasionally the hold does not drop off on schedule. Usually there is an ordinary reason behind it: a bank that releases blocks in a nightly batch, a technical rejection of your bid that leaves the status unclear, a UPI mandate you never expired or cancelled, or a mismatch between your demat and bank details. None of these means your money is gone — it means the hold needs a nudge. Before you panic, work through this ladder in order, and most cases resolve at step one or two.
- Confirm your allotment status first. Check the registrar's website or the exchange portal to see whether you were allotted, partly allotted, or not allotted. A pending status is different from a stuck refund. Our step-by-step guide to checking your IPO allotment status online shows exactly where to look.
- Raise it with your bank. The bank or SCSB holds the block, so it is the first port of call. Quote your application number and the IPO name, and ask them to release the un-allotted amount.
- Contact the registrar and lead manager. The registrar (names such as Link Intime or KFin Technologies appear in the offer document) coordinates allotment and can confirm whether the unblock instruction was sent to your bank.
- Escalate to SEBI's SCORES portal. If the bank and registrar do not resolve it, file a complaint on SEBI's investor grievance platform, SCORES. Unresolved disputes can also go to online dispute resolution under the SMART ODR framework.
Importantly, a delay is not only your problem to chase. SEBI entitles you to compensation if your ASBA funds are not unblocked on time. Under SEBI's circulars of March 2021 and April 2022, the bank must pay the higher of a per-day charge or an annualised rate on the blocked amount, and under the T+3 cycle the delay is counted from the T+3 day.
You are owed compensation for a late unblock
Keep screenshots of your bid confirmation and bank block. They are all the evidence you need to claim compensation, and they make a SCORES complaint far quicker to resolve.
What to do next
The IPO refund and unblocking timeline is one of the calmest parts of investing once you understand it: apply, let the money sit blocked in your own account, and watch it free up around T+2 if the allotment does not come your way. There is no cheque to wait for and no payment to reverse — only a hold that lifts on a published schedule.
Treat the escalation ladder as insurance you will rarely use. Check your allotment status, give the bank its T+3 window, and escalate with your screenshots if the block lingers. For most applicants, the money is back before they even think to look.
If the primary market still feels like a black box, the fix is structured learning rather than trial and error across a dozen issues.

When is IPO money unblocked if you get no allotment?
Under the T+3 listing cycle, un-allotted ASBA funds are unblocked by about 4 PM on T+2 — the second working day after the issue closes, and one day before the shares list. The amount was only blocked in your own bank account, so it simply returns to your free balance once the hold is lifted.
Is there a separate refund for IPO applications?
No. ASBA does not involve a payment, so there is no refund cheque or transfer. Your application amount is held in your bank account and released if shares are not allotted. For UPI applications, your bank revokes the mandate; for bank ASBA, it lifts the lien on the un-allotted portion.
What should you do if IPO funds are not unblocked on time?
First confirm your allotment status on the registrar's site. Then raise it with your bank, which holds the block, followed by the registrar. If it is still unresolved, file a complaint on SEBI's SCORES portal. Keep your bid and block screenshots as evidence throughout.
Does SEBI pay compensation for a delayed unblock?
SEBI rules require your bank to pay compensation if ASBA funds are not unblocked within the stipulated time — the higher of ₹100 per day or 15% per annum on the application amount, counted from the T+3 day. You claim it through your bank, with escalation to SCORES if needed.
Do you earn interest on blocked IPO money?
Yes. Because the money stays in your own savings account and is only blocked, it continues to earn your normal savings interest until it is either debited for allotted shares or unblocked. This is one of the quiet advantages of the ASBA route over older refund-based systems.
