1- what will be GST tax rate will be apply on the service of resturant service ( Food, Cold Drinks,Mineral water,coffee,Tea fast food etc ) such as 5%,12%,18%
If the value of service charged for accommodation does not cross 7500 per day per room, then restaurant service will be liable @ 5% with no ITC.
2- if he opt GST 5%, can he charge GST from customers under regular basis optopn
If composition scheme then cannot collect GST from customers. But under regular scheme (which is also 5% GST), GST can be collected from customers. I dont understand why will anyone opt for composition for restaurant since rate of tax and ITC conditions are similar.
3- can be taken benefit of ITC on purchase of material of assets and raw material.
If restaurant 5% then no ITC. Can claim ITC for accommodation services as per rule 42 and 43
4- If he provide food in rooms what will be GST rate applicable
Food in room is generally not part of accommodation package. Will not be a composite supply. Will be liable at the rate applicable for the restaurant service @ 5%
5- If he provide grounds for functions, what will be GST rate tax applicable
if this is only renting without any food supply then not an outdoor catering service. Liable @ 18%
However, if it is a contract of outdoor catering then we would require to examine whether the person is a supplier of services specified premises or the premises where the supply is provided is a specified premises.
