Quick answer: Tatkal booking opens at 10:00 AM for AC classes and 11:00 AM for non-AC (sleeper) classes, one day before the train’s departure from its origin station. Seats for popular trains finish in under two minutes, so the win comes from preparation: log in by 9:57, use a saved passenger list (Master List), pay with UPI or IRCTC eWallet, and click “Book” the second the clock hits 10:00:00. This guide covers the exact sequence, the timing tricks, and what to do if the payment page hangs.
Tatkal rules you need to know
| Rule | Detail |
|---|---|
| Opening time | 10:00 AM (AC: 1A, 2A, 3A, 3E, CC, EC); 11:00 AM (SL, 2S) |
| Booking day | One day before the journey date, counted from the train’s origin station, not your boarding station |
| Max passengers per PNR | 4 (Tatkal); 6 for general booking |
| ID proof | Not entered at booking; any one passenger carries a valid photo ID while travelling |
| Tatkal charge | About 10% of base fare (2S), 30% for other classes, within minimum and maximum limits |
| Refund on cancellation | No refund for confirmed Tatkal tickets; waitlisted Tatkal cancelled before chart gets a refund minus clerkage |
| Agents | Authorised agents cannot book opening-day Tatkal in the first 30 minutes (10:00–10:30 and 11:00–11:30) |
| Aadhaar verification | Online Tatkal requires Aadhaar-authenticated users and Aadhaar-based OTP authentication |
Complete Aadhaar authentication before booking and keep access to the linked mobile for the required OTP.
The day before: 10 minutes of setup
- Create a Master List. IRCTC → My Account → My Profile → Master List. Add every passenger with name, age, gender, berth preference, and ID. During booking you tick names instead of typing.
- Save the train. Search the route once and note the train number and class. On booking day, type the number directly rather than browsing.
- Set up the fastest payment. UPI and IRCTC eWallet are quickest. Net banking pages are slow and time out. Keep the UPI app open on your phone.
- Update the app. Old versions of IRCTC Rail Connect fail at login during peak load.
- Check your login. Reset the password now if you are unsure; you will not have time at 10:00.
Booking day: the exact sequence
- 9:55 AM: log in on irctc.co.in or the app. Do not log in much earlier; sessions time out after 10 minutes of inactivity and you risk being logged out at 9:59.
- 9:57 AM: enter From, To, date, and select the Tatkal quota. Search. Find your train and class.
- 9:59 AM: keep the page ready. The Book Now button activates only at 10:00.
- 10:00:00 AM: click Book Now immediately. Your device clock may be a few seconds off; watch the IRCTC server time shown on the page.
- Passenger page: tick names from the Master List, confirm berth preference, tick “Book only if confirm berths are allotted” only if you do not want a waitlist. Enter the captcha. Click Continue.
- Review page: check names once and click Continue. Do not go back; a berth is not guaranteed until booking succeeds.
- Payment: choose UPI, approve on your phone within seconds. If the page hangs, do not refresh; wait 30 seconds, then check My Transactions → Booked Tickets before trying again.
Tricks that actually help
- Avoid simultaneous duplicate bookings for the same journey; both attempts could create tickets and charges.
- Keep captcha bookmarklets and autofill extensions off. IRCTC detects them and blocks the session.
- Try the 11:00 sleeper window if AC fails. Same train, different quota release.
- Check the boarding-point trick: Tatkal quota is calculated from the train’s origin. If your station is mid-route, you may find seats booking from the origin and changing the boarding point (allowed once before chart).
- Waitlist confirmation is uncertain. Check alternatives and do not rely on a numerical waitlist position as a guarantee.
- Premium Tatkal: some trains have dynamic-price Premium Tatkal quota that stays open longer; expensive but reliable for emergencies.
If it goes wrong
| Problem | What to do |
|---|---|
| “Session expired” at 10:00 | You logged in too early. Log in again fast; seats may still be available for 60–90 seconds |
| Payment debited, no ticket | Check My Transactions after 5 minutes. IRCTC’s app user guide shows a failed-payment message saying the deducted amount is refunded automatically within 3–4 working days; treat this as guidance for that case, check the refund status, and contact IRCTC or your bank if the credit is missing |
| Captcha keeps failing | Try the official IRCTC Rail Connect app instead; it is not guaranteed to be faster |
| Seats gone in 30 seconds | Try the 11:00 quota, a different class, or a nearby origin station |
| Website not loading | Try the other official channel (app or website); neither is guaranteed to work better |
Frequently asked questions
Can I book Tatkal for a journey starting today?
No. Tatkal is only for the next day’s departure from origin, opening at 10 and 11 AM the day before.
Is ID required at booking?
No ID is entered while booking. During the journey, any one passenger must carry a valid original photo ID.
Can I change passenger names on a Tatkal ticket?
No name changes are allowed on Tatkal tickets.
Is there a refund if the train is cancelled?
Yes. If Indian Railways cancels the train, the full fare is refunded automatically, including Tatkal charges.
Rules and timings reflect IRCTC policy as of September 2026. Indian Railways revises Tatkal rules periodically; check the IRCTC website for the latest notice before travelling.
Correction (22 September 2026): earlier versions said failed-booking refunds arrive within 3–7 days and that the app’s captcha loads faster. Neither was supported; the refund line now follows IRCTC’s own guide, and the app-speed claims have been removed.
Sources
Failed-payment refund guidance is from the IRCTC Rail Connect app user guide. It does not cover cancellation refunds or TDR claims.
