NTA opened JEE Main 2027 Session 1 registration on 24 October 2026. The Indian Express, India Today and The Times of India all report the same close: 22 November 2026 at 11:50 pm on jeemain.nta.nic.in, without a late fee. A late window with an extra Rs 500 is reported for 23 to 26 November, and a correction window for 27 to 29 November. Those reports also list the January papers on 20, 21, 22, 23, 24 and 28 January 2027, with the admit card on 13 January. Pay only on the NTA site. A coaching page can copy a date and still be wrong after NTA revises the notice.
Apply at jeemain.nta.nic.in before 22 November if you want to avoid the late fee. Save the application number and the payment receipt. Check the official notice again on the day you pay.
