How much revenue could an 100% land value tax be able to generate for the Indian government?
In Australia, Prosper compiled a survey of all economic rents and came to the conclusion that the Australian government could effectively be funded with rents alone.
This is without taking into account that abolishing taxes will further increase the value of economic rents, i.e. in the absence of taxation firms and households will have more net income to pay for economic rents (land, carbon, licences, fees) which further increases government revenues.
Mason Gaffney (2009) argues that all taxes come out of rents (ATCOR). According to this a tax reduction would increase rents by at least the same amount. This would imply that a government funded with taxes could just as well be funded with rents. See my question about ATCOR here.
