Practically none. Probably one that may be available ( even I have to check as it has lost its commercial relevance) , is in case you decide to import some machinery to be used in business it can be imported without payment of customs.Based on my experience in business consulting, my advice would be not to start any business in India based on expectations from Government, up till now Government might have announced 1000s of schemes but very few of business could enjoy benefits out of these schemes.The latest is Start up India, if you are fond of reading, search on this subject.Be at at your own, if you have faith in yourself and your idea nothing else ,only then jump in business.All the Best.
