The minimum age required to appear for NEET UG is 17 years as of 31 December of the year of admission. For example, a candidate appearing in NEET 2026 must be born on or before 31 December 2009. Previously, there was an upper age limit of 25 years for general category candidates and 30 years for reserved categories, but this restriction has been removed following court rulings and policy revisions. Therefore, currently there is no official upper age limit for NEET UG, allowing candidates of any age who meet the educational requirements to appear for the exam.
