Hello There,

If you have been allocated a seat in Round 1, and paid the seat acceptance fee , but you prefer to ‘Slide’ and ‘Freeze’ a seat in the later rounds, then also you don’t have to pay the seat acceptance fee again. And if you haven't been allocated the college then there is no need to pay for the counselling of 1st round you can wait for the second round and you have to pay seat acceptance charge after seat allotment.

According to JOSAA -  " A candidate, who has already accepted a seat allotted by JoSAA ,can withdraw the seat by reporting at a reporting center before the last round of seat allocation (i.e., if JoSAA conducts a total of four rounds of seat allocation, candidates can withdraw up until during third round of seat acceptance period). "

" Candidates who have exercised withdraw option will not be considered for subsequent rounds of seat allotment. Seat acceptance fee will be refunded to these candidates after deducting the processing charges of Rs 1000/-. There is no option of withdraw of an accepted/allotted seat after the announcement of last round of seat allocation. "

Hope it Helps :)
