The movie has been produced by filmmaker Sanjay Leela Bhansali.
"It is wonderful news. We have a compelling story to tell of a strong, determined woman who has done the nation proud. It is our tribute to all the unsung sports people who give so much to see the Indian flag flying high.
“If this can act as a catalyst of hope for them, then its something we can all be proud of," Chopra, who is playing the five-time world champion in “Mary Kom,” said in a statement here.
"We are grateful to Revenue Minister Balasaheb Thorat and the government of Maharashtra for lending their support to the film. This exemption right from release day will allow large segments of society to experience the spirit of magnificent Mary," said producer Ajit Andhare, COO, Viacom18 Motion Pictures.
Meanwhile, Bhansali’s spokesperson said the tax-free status will encourage audiences to recognize and support the spirit of the film.
Based on the true story of Mary Kom, the biopic chronicles the journey of a woman boxer who gave up her sporting career when it was at its peak to embrace the joy of motherhood. After giving birth to two beautiful children, she made her comeback in the ring and went on to become both a stronger woman and a stronger boxer.
The film, directed by Omung Kumar, is set to release Sept. 5.
Earlier, various state governments including Bihar, Uttar Pradesh and others had granted tax exemption to Farhan Akhtar-starrer “Bhaag Milkha Bhaag,” a biopic on legendary athlete Milkha Singh.
