The Gujarat Government issued an official notification in this regard.
The announcement was made this evening, shortly after the movie's producer, Atul Kasbekar, and Sonam's father, Bollywood star Anil Kapoor, held a brief meeting with Chief Minister Anandiben Patel in Gandhinagar.
"We were here to make an appeal to the CM about making the movie tax-free. We are confident the CM will consider our appeal," Kapoor told media persons after the meeting.
"During the meeting, the Chief Minister praised the subject of the movie," said Kasbekar.
Directed by Ram Madhvani, the biographical film stars Sonam in the titular role of flight attendant Neerja. The movie revolves around the 1986 hijacking of Pan Am Flight 73 in Karachi and how the 22-year-old Neerja fought for the lives of her passengers.
Maharashtra has already declared the film tax-free.
