"Yay! #MaryKom declared tax free in Maharashtra a week before release! Amazing!! #Sept5," Priyanka posted on Twitter.
The movie is a biopic on the five-time World Champion boxer M.C. Mary Kom. It is slated to release on Teacher's Day Sep 5.
Omung Kumar, who is making his directorial debut with the movie, confirmed the news to IANS via sms, while Ajit Andhare, chief operating officer of the film's co-producers Viacom18 Motion Pictures thanked the Maharashtra government for the support.
"'Mary Kom' celebrates a national hero, who as we speak is still competing to bring laurels to the country (she will be competing at the Asian Games). We are grateful to the government of Maharashtra for lending their support to the film," Andhare said.
"They also supported 'Bhaag Milkha Bhaag' and now this exemption right from release day will allow large segments of society to experience the spirit of magnificent Mary," he added.
