The Joint Admissions Committee (JAC) has officially initiated the IISER seat allotment 2026 process today, 24 July 2026, with the Round 1 allocation schedule commencing at 5:00 PM. Candidates who qualified the IISER Aptitude Test (IAT) and completed choice filling between 2 July and 9 July 2026 can now access their offer letters through the official portal at iiseradmission.in.
This allotment cycle allocates seats across 7 participating campuses—including IISER Pune, Kolkata, Mohali, Bhopal, Thiruvananthapuram, Tirupati, and Berhampur—offering over 2,100 total seats in 5-Year BS-MS Dual Degree and select 4-Year BS/BTech programs. Qualified candidates must pay their Seat Acceptance Fee (SAF) by 28 July 2026 to secure their allocated seat.

Key Highlights and Timeline for IAT 2026 Counselling
This year’s admission cycle is especially significant as IAT 2026 serves as the primary gateway following the discontinuation of the KVPY and JEE Advanced channels for IISER undergraduate entry. The entire allocation mechanism relies on candidate ranks, category reservations, and preferred choices.
Candidates expecting a seat in the initial round should note the crucial upcoming dates for the counselling schedule:
-
Round 1 Allotment Announcement: 24 July 2026 (5:00 PM)
-
Round 1 SAF Payment & Decision Window: 24 July 2026 to 28 July 2026 (5:00 PM)
-
Round 2 Seat Allotment: 1 August 2026
-
Round 2 SAF Deadline: 5 August 2026
-
Round 3 Seat Allotment: 10 August 2026
Candidates participating in IAT 2026 counselling should monitor these deadlines closely, as missing a submission window results in automatic seat forfeiture.

To confirm either option, candidates must submit the required Seat Acceptance Fee online. The SAF stands at ₹35,000 for General/OBC/EWS candidates (including a ₹10,000 non-refundable processing fee) and ₹17,500 for SC/ST candidates.
