CAT 2026 Correction Window (Expected): Dates, Editable Fields, Fee and How to Apply

CAT 2026 Correction Window

CAT 2026 registration closed on September 22, 2026, after IIM Indore extended the original September 15 deadline. IIM Indore is now expected to open a correction window that lets registered candidates fix errors in their CAT 2026 application form before the exam on November 29, 2026. As of this writing, IIM Indore has not officially released the correction window dates, so this article presents carefully reasoned estimates alongside everything candidates need to know: who can use the window, what can and cannot be edited, the fee involved, and how the dates compare with previous CAT cycles.

IMPORTANT: IIM Indore has not officially announced the CAT 2026 correction window dates. All dates in this article for the correction window are ESTIMATES / TENTATIVE, based on historical trends and current news reporting, and must be reconfirmed on iimcat.ac.in.

Key Takeaways

• The CAT 2026 correction window is expected (tentative, unofficial) to open around October 5, 2026, and close around October 8, 2026 — IIM Indore has not confirmed these dates yet.

• Only candidates who registered and paid the CAT 2026 application fee by September 22, 2026, will be able to access the correction window.

• Editable fields are expected to be limited to photograph, signature, and test city preference, based on the pattern from previous years.

• Core details — date of birth, email ID, mobile number, category, and academic qualifications — are not expected to be editable.

• There is expected to be no fee for using the CAT 2026 correction window, consistent with every previous CAT cycle.

• The gap between registration closing and the correction window opening has widened every year: 2 days (2022), 4 days (2023), 7 days (2024), and 14 days (2025).

CAT 2026 Important Dates

CAT 2026 registration ended on September 22, 2026. IIM Indore is yet to release the CAT 2026 correction window dates; the entries below marked “Expected” are tentative estimates, not official dates. The table also lists the confirmed dates for the admit card and exam.

Who Can Use the CAT 2026 Correction Window?

The CAT 2026 correction window is expected to be available only to candidates who have:

• Registered for CAT 2026 within the prescribed deadline (by September 22, 2026).

• Successfully submitted the CAT 2026 application form.

• Paid the applicable CAT 2026 application fee in full.

• Valid CAT 2026 login credentials (registration number/ID and password).

IIM Indore has consistently stated in previous years that the edit facility is available only to candidates who registered and paid the applicable fee within the prescribed deadline — candidates who missed the registration deadline will not be able to use the correction window.

How to Use the CAT 2026 Correction Window

Once the correction window opens, candidates can edit their CAT 2026 application form by following these steps:

• Click on the CAT 2026 application form / correction window link.

• Log in using your CAT 2026 registration number/ID and password.

CAT 2026 Correction Window: What Can and Cannot Be Edited

Based on the pattern followed in every recent CAT cycle, the correction window allows only a limited set of edits. The table below summarizes what is expected to be editable and what is not.

CAT 2026 Test City Change Preference

Test city preference is one of the details candidates are expected to be able to change during the CAT 2026 correction window. However, changing a preference does not guarantee allotment — the final test centre and city are allotted by IIM Indore based on seat availability at each location.

CAT 2026 Correction Window Fee

Based on every previous CAT cycle, there is expected to be no fee for the CAT 2026 application form correction. IIM Indore has not charged candidates for making permissible modifications in past years, and the correction window is expected to remain free of cost for CAT 2026 as well. Candidates would simply open the application form online, make the required changes, and resubmit it — with no additional payment step.

CAT Correction Window Date Trends (Past Years)

The exact CAT 2026 correction window dates are not yet confirmed, but the table below shows how the gap between registration closing and the correction window opening has changed over the past four CAT cycles — useful context for why October 5–8, 2026 is a reasonable estimate for this year.

The gap between registration closing and the correction window opening has widened every year, from 2 days in 2022 to 14 days in 2025. Applying the exact 14-day CAT 2025 gap to this year's September 22 closing date would suggest an opening around October 6, 2026; most current reports place the expected window at October 5–8, 2026. Either way, candidates should treat early October 2026 as the realistic window and confirm the exact dates on iimcat.ac.in once announced.
