Aamir Khan says the makers of the forthcoming film 'Dangal' will apply for tax exemption.

"I think 'Dangal' falls in the line of tax exemption. We will be applying for tax exemption, but I am not someone to decide on that. It will be the decision of each state government. We will try to make it happen before the release, but it is a process. It may or may not happen," Aamir said.

In the biopic, Aamir will play Mahavir Singh Phogat, father of wrestler Geeta Phogat, who won India's first ever gold medal in wrestling at the Commonwealth Games in 2010.

Asked if demonetisation will affect the box office collection of the film, Aamir said: "I hope not."

Directed by Nitesh Tiwari, the sports drama is set to release on December 23.
