The move is aimed at providing support to local population, a large part of whom depends on hospitality industry for their survival.
The exemption is given to services like renting of a room in a hotel, inn, guest house, club, campsite or other commercial place meant for residential or lodging purposes and for the ones provided in relation to serving of food or beverages by a restaurant and eating joint or mess, a Finance Ministry order said.
Floods and landslides on June 16 had caused extensive damage in Uttarakhand.
"There is a need to provide support to ensure sustenance for the local population by revival of the hospitality industry," it said, adding that the decision to exempt these services was taken in public interest as also there are circumstances of "exceptional nature".
As many as 4,120 persons, including 92 foreign nationals, have been reported missing in Uttarakhand after the calamity, as per a latest official data.
