JoSAA 2026 Round 4 Seat Allotment

Round 4 was mechanically identical to every other JoSAA round — Float and Slide candidates from Round 3 were re-processed against newly vacant seats, and unallotted candidates were re-evaluated too. What made it distinct was its position in the calendar: with Round 5 as the hard final round, Round 4 was effectively the last "normal" round where a Float decision carried genuine long-term upside without the pressure of it being the absolute last chance.

Seat movement volume in Round 4 was noticeably smaller than in Round 2 or even Round 3. By this stage, a large share of candidates satisfied with a top-30 NIT or established IIT branch had already Frozen. The candidates still actively Floating into Round 4 tended to be concentrated at two extremes: very high-rank candidates chasing a specific IIT branch (say, moving from IIT Guwahati to IIT Kanpur CSE) and moderate-to-lower-rank candidates still hoping to move from a GFTI or newer IIIT into an established NIT.

This round also carried an important category-specific dynamic. Home-state quota seats at NITs — which reserve a fixed proportion for candidates domiciled in the NIT's home state — often showed their final closing-rank adjustments in Round 4 rather than Round 3, because Other-State (OS) quota candidates exiting the process freed up cascading vacancies that took a round longer to reach Home-State seekers in the merit order. EWS and OBC-NCL candidates in particular saw meaningful last-minute movement in Round 4 for exactly this reason.

The IIT/IISc withdrawal deadline of July 14, 2026 sat just four days after the Round 4 result — a genuinely tight window. This deadline is unique to IIT/IISc seats: candidates allotted an IIT or IISc seat who wished to withdraw with the standard refund rules had to act before July 14, since after Round 5 those seats become effectively locked in place with no further withdrawal option under the same terms. This is a materially different rule from NIT/IIIT/GFTI seats, which follow their own separate, later withdrawal and reporting schedule — see our dedicated withdrawal after Round 5 guide for the full breakdown.

A common error at the Round 4 stage was candidates delaying their withdrawal decision because they assumed Round 5 would bring a large upgrade — historically, Round 5 (the final round) brings the smallest movement of the entire process, since almost all remaining Float candidates by that point are chasing very specific, hard-to-get seats. Treating Round 4 as effectively "your last real shot" was the more accurate mental model.
