When exactly does CAT 2026 registration close?

At 5 PM on 15 September 2026. Not midnight. That single detail catches people out every year, because most online deadlines in India run to the end of the day and this one does not.

Your form counts as submitted only when the payment succeeds and your status reads registered. A payment you start at 4.55 PM and watch fail is not a submission. Cards get declined, bank pages time out and the site is at its slowest on the last two days, when a few lakh people are all doing the same thing.

Give yourself a buffer. Finish and pay by 13 September, then use the last two days only to check what you filled.

Will the date be extended?

Nothing has been announced. IIM Indore has published one date and the bulletin carries no late window. Registration for the previous CAT cycle did get pushed to 20 September, so an extension is not impossible. You will also still see 20 September sitting on a few coaching sites because nobody updated the page.

Treat that as noise. Betting Rs 2,700 and a full year on a rumour is a poor trade when the fix costs you one evening.

What you can change after 15 September and what locks forever

Once you submit, almost everything is frozen. The correction window that opens after the deadline touches three fields only.

Field

Can you change it after you submit?

The correction window is only for candidates who registered and paid successfully before the deadline. IIM Indore announces the dates on iimcat.ac.in. A date of 27 September is circulating on coaching sites, but it is not in the official bulletin, so check the site rather than trusting it.

What to get ready before you submit

Almost every rejected form fails on a certificate, not on eligibility. Sort these out first.

  • Photograph and signature, scanned. The exact pixel and file size limits live in the registration guide on iimcat.ac.in, not in the bulletin, so read them there before you resize anything.
  • NC-OBC certificate issued on or after 1 April 2026. An older one will not do.
  • EWS certificate valid for 2026-27 and specifically assessed for financial year 2025-26.
  • Applied for the certificate but not received it yet? Upload one PDF holding the filled undertaking from the CAT site, your older certificate and the acknowledgement of your new application. An incomplete set can cost you the application.
  • PwBD candidates should get a UDID card and upload it. Benchmark disability means 40 percent or more of a specified disability under the RPwD Act 2016.
  • Degree numbers. You need a bachelor’s with 50 percent, or 45 percent if you are SC, ST or PwBD. Final year students can apply. If your university has no certified conversion method, use CGPA divided by maximum CGPA, times 100.

CA, CS and CMA count as professional degrees for eligibility.

Test city choice is the field most people rush

You pick five cities in order of preference. Allotment happens after registration closes. If your choices fill up you can be sent to a nearby city instead. Once a centre is allotted it does not change.

So pick for the journey you can make on a Sunday morning in late November, not for the shortest distance on a map. A city with a 6 AM train you would have to catch is worse than one an hour further out with a hotel you can book.

The fee and what a failed payment looks like

Rs 2,700 for general, EWS and NC-OBC candidates. Rs 1,350 for SC, ST and PwBD. You pay once and it covers every IIM programme you apply to. It is not refundable, whatever happens later.

After paying, log out and log back in. Your dashboard should show the registration as complete. Download the confirmation PDF and keep a screenshot. If money left your account but the status has not moved, wait a few hours before paying again, then call the help desk on 1800 210 0175 or write to cat2026_helpdesk@iimidr.ac.in.

Should you register if your mocks are nowhere near ready?

Yes. Register anyway.

The fee buys an option, not an obligation. Nothing forces you to sit the paper on 29 November. A CAT score stays valid until 31 December 2027. What you cannot buy in October is a registration you skipped in September.

I have watched this play out with plenty of people. Somebody decides in August that this is not their year, then has a good six weeks, walks into a 90 percentile mock in mid October and there is nothing to do with it. Rs 2,700 is less than a month of coaching. Pay it and decide in November.

If you do register, the real question is what to do with the weeks between now and the exam. There is a week-by-week plan you can follow.

Frequently Asked Questions

Will CAT 2026 registration be extended beyond 15 September?

No. Category is locked at submission. The certificate has to be uploaded during registration. The correction window covers the photograph, the signature and test city preferences only.

What happens if I miss the CAT 2026 deadline?

There is no reopening and no offline form. You would have to wait for CAT 2027, which is written in November 2027. For the same admission year you can still look at XAT, NMAT, SNAP and the other MBA entrance exams, whose registration windows run later in the year.
