JoSAA Undertaking Form: Formats, Rules & How to Fill

During JoSAA counselling and online reporting, candidates frequently run into document discrepancies or missing certificates. When this happens, students search urgently for the JoSAA undertaking form to prevent their seat from being cancelled.

An undertaking in JoSAA is an official self-declaration submitted on a prescribed format. Here is a factual guide to what undertakings exist, who needs them, when JoSAA rejects them, and how to fill and upload them correctly.

What is a JoSAA undertaking?

A JoSAA undertaking is a formal written declaration signed by the candidate and their parent or legal guardian. It is submitted through the JoSAA candidate portal during online reporting or in response to a query raised by verifying officers.

Under ordinary circumstances, you must upload original, valid documents. An undertaking is used only for specific situations sanctioned under JoSAA Business Rules—such as declaring Non-Creamy Layer status, declaring withdrawal from seat allocation, or undertaking category conversion.

[!NOTE] JoSAA undertakings are standard PDF forms published directly on the official portal (josaa.nic.in). Unless you have an official name mismatch requiring a legal affidavit, you do not need stamp papers or court notarisation for standard JoSAA undertaking forms.

When is an undertaking needed in JoSAA?

During online reporting, the verifying officer checks every scanned document. If an uploaded document is questionable, a portal query is raised. This is where an undertaking is commonly required:

Under the official JoSAA certificate formats and Business Rules, there are four primary types of undertakings and declarations:

1. Form – Undertaking for OBC Candidates

• Who needs it: Candidates allotted a seat under the OBC-NCL category.
• What it declares: The candidate declares that they belong to a community recognized as backward by the Government of India (Central List, available on ncbc.nic.in), that they do not belong to the Creamy Layer, and that parental income is within the prescribed limits for the financial year ending on March 31 of the examination year.
• Key requirement: It must be signed and dated by the candidate. Any undertaking submitted without the candidate’s signature is rejected automatically.

2. Annexure 8: Seat Withdrawal Form (Withdrawal Undertaking)

• Who needs it: Any candidate who was allotted and accepted a seat in Rounds 1 to 5 but wishes to exit counselling and claim a partial refund of their Seat Acceptance Fee.
• What it declares: You state your allotted institute and branch, mother’s name, reason for withdrawal, and confirm you understand that your seat will be cancelled and that you are forfeiting eligibility for any further JoSAA rounds.
• Signatures required: Both candidate and parent/guardian signatures are strictly mandatory. JoSAA explicitly states that a withdrawal request without the parent’s signature will be rejected.

3. Maharashtra Caste Validity Certificate Undertaking (NIT+ System)

• Who needs it: SC, ST, and OBC-NCL candidates from Maharashtra State taking admission in the NIT+ system (NITs, IIEST, IIITs, GFTIs).
• Why it is needed: Maharashtra requires caste certificates to be validated by the Social Welfare Department (for SC and OBC) or Tribal Welfare Department (for ST). If the validation process is pending, candidates must upload this specific undertaking format from the JoSAA portal promising submission before physical reporting.

4. Category Change Undertaking / Query Response Declaration

• Who needs it: Candidates who claimed GEN-EWS, OBC-NCL, SC, or ST during registration but whose certificate is rejected during online verification (e.g., certificate issued before April 1, 2026, or issued in a state format not on the central list).
• What it declares: The candidate accepts conversion to the OPEN / General category under Clause 74 of the JoSAA Business Rules, provided their All India Rank (CRL) meets the General cutoff.

When an undertaking is NOT accepted

Many students assume an undertaking can buy time for any missing paper. That is false. Under JoSAA Business Rules, the verifying officers will reject your documents and cancel your seat if you submit an undertaking for the following:

• Class 10 certificate / Birth Certificate: Required as mandatory proof of Date of Birth.
• Class 12 marksheet: You must meet the 75% aggregate criteria (65% for SC/ST/PwD) or be in the top 20 percentile of your board. An undertaking cannot substitute for failing or missing marks.
• PwD Certificate / UDID Card: Candidates claiming PwD reservation cannot defer their disability proof. For IITs, candidates must also appear for scheduled physical verification at an IIT/IISc reporting centre.
• Seat Acceptance Fee (SAF): ₹30,000 (GEN/OBC/EWS) or ₹15,000 (SC/ST/PwD). JoSAA does not permit fee payment deferrals. Document verification begins only after the fee is paid online.

What happens if your category certificate is invalid?

If you cannot produce a valid central category certificate or an accepted undertaking during the online verification window, JoSAA does not immediately disqualify you from the exam—instead, your category tag is modified according to Clause 74:

If your category changes to GEN:

1. If your General CRL was sufficient to obtain the seat in that round, your seat will be re-allocated under OPEN in the next round.
2. If your General CRL is not high enough for that particular seat, the seat is cancelled, but you remain eligible for subsequent rounds under the OPEN category.

How to download, fill, and upload the undertaking

Follow these steps when prompted to submit an undertaking:

1. Download the exact official form: Go to josaa.nic.in and click on Certificate Formats. Never download blank formats from untrusted coaching blogs.
2. Fill in all details accurately: Write your full name and Roll Number / Application Number exactly as shown on your JEE Main and JEE Advanced admit cards.
3. Double-check signatures: Ensure you sign and your parent/guardian signs where indicated. An unsigned form will trigger an immediate discrepancy query.
4. Scan clearly to PDF: Scan the entire page in high resolution (avoid shadows, cropped edges, or blurred text). Keep the file size within the JoSAA upload limit (typically 100 KB to 500 KB).
5. Upload under Query Response: Log into the JoSAA reporting portal. Navigate to the Seat Acceptance / Query Response tab, upload the PDF, and click submit. Monitor your portal dashboard until the verifying officer approves the upload and changes your status to “Seat Confirmed”.
