GATE 2026 IIT M.Tech Document Checklist for COAP Seat Acceptance and Institute Reporting

Students who have received and accepted an IIT M.Tech seat through COAP 2026 must submit a specific set of documents both during online seat acceptance and at the time of physical reporting to the institute — missing a single document can delay or cancel admission.

The Common Offer Acceptance Portal (COAP) is managed by IIT Kharagpur on behalf of all participating IITs and is the single platform for accepting or rejecting M.Tech, MS, and PhD offers based on GATE 2026 scores. Once you accept and freeze a seat, you must pay the acceptance fee online and then physically report to the allotted IIT on the date specified in your offer letter, carrying all required originals and self-attested copies. This checklist covers every document you need at both stages.

• COAP 2026 runs in multiple rounds, allowing you to hold and compare offers from different IITs before freezing a seat.
• Online seat acceptance requires payment of the acceptance fee and uploading select documents on the COAP portal before the round deadline.
• Physical institute reporting requires originals and at least two sets of self-attested photocopies of all academic, identity, and category documents.
• All details in your documents must match your GATE 2026 registration data exactly — any mismatch can lead to cancellation of the offer.
• IIT M.Tech institute reporting for COAP 2026 final rounds is expected around July 2026; check your individual IIT’s offer letter for the exact date.

What is COAP and How Does Seat Acceptance Work?

COAP (Common Offer Acceptance Portal) is a centralised platform operated by IIT Kharagpur that lets students who have applied to multiple IITs receive, compare, and respond to admission offers in a structured round-based process. It removes the need to separately log in to each IIT portal to track offer status.

The typical COAP 2026 seat acceptance flow for IIT M.Tech works as follows:

1. Register on the COAP portal using your GATE 2026 registration number, enrolled email, and password set during application.
2. View offers from one or more IITs in the current COAP round on your dashboard.
3. Accept your preferred offer or reject offers you do not want before the round deadline shown on the portal.
4. Pay the seat acceptance fee to the allotted IIT through the payment link sent in the offer confirmation email.
5. In the final COAP round, freeze your seat and report physically to the IIT with all required documents on the specified date.

Students who miss the COAP round deadline for acceptance automatically forfeit that offer. If you hold an offer from a lower-preference IIT and a better offer arrives in a later round, COAP allows you to upgrade — but only if you have not yet frozen your seat.

Documents for Online Seat Acceptance via COAP

At the time of accepting an offer on the COAP portal, you may be required to upload scanned documents or enter details from the documents below. Keep scanned copies ready in PDF or JPEG format (file size as specified on the portal) before each round deadline.

Individual IITs may also ask you to fill a separate online reporting form on their own admissions portal after COAP seat acceptance is complete. Read the full offer letter from your allotted IIT carefully for any institute-specific instructions.

Documents for IIT Institute Reporting

After your seat is frozen in the final COAP round, you must physically report to the allotted IIT on the date specified in the offer letter. Carry all original documents and at least two sets of self-attested photocopies in a well-organised folder. The table below lists the documents required at most IITs for M.Tech admission based on GATE 2026.

If you are in your final year of B.Tech / BE at the time of reporting, carry a bonafide or completion letter from your institution confirming your expected graduation date along with all available semester marksheets. Your IIT will set a deadline — usually by October or November of the joining year — by which you must submit the final degree certificate and consolidated marksheet.

Category-Wise Additional Documents

Students admitted under reserved categories or with a disability must carry the documents listed below in addition to the standard checklist. Certificates must be issued by the competent authority in the prescribed central government format.

OBC-NCL certificate validity is especially critical — if your certificate was issued more than one year before the date of institute reporting, you must obtain a fresh certificate from a competent state authority before arriving at the IIT. An expired OBC-NCL certificate results in automatic rejection of the category claim, which can affect both admission eligibility and fee concessions.

Tips for Document Preparation

Organising your documents ahead of time prevents last-minute stress and avoids a situation where a missing certificate holds up your entire admission process. Apply these practical steps before your reporting date.

• Self-attest every photocopy by signing across the front and writing "Self-Attested" with the date.
• Download and print your GATE 2026 scorecard from the GOAPS portal before the portal closes; do not rely on being able to download it at the last minute.
• Visit your allotted IIT’s official admissions page and download any institute-specific forms such as undertakings, indemnity bonds, or hostel forms — these often need to be printed, filled, and signed before you arrive.
• Apply for your migration certificate at least three to four weeks before the reporting date — universities typically take two to four weeks to process this request.
• Get both anti-ragging affidavits (student and parent) notarised by a notary public; most IITs do not accept un-notarised copies.
• Carry originals and copies in clearly labelled separate folders so you can hand over copies quickly at each verification counter without touching your originals.
• If your name or date of birth differs across documents — for example, between your marksheet and Aadhaar — carry a gazette notification or a sworn affidavit explaining the discrepancy to avoid rejection at verification.
• Check your bank account for the seat acceptance fee debit and carry a printout of the transaction receipt; some IITs ask for this at the fee counter during reporting.
