In law, stamp duty is chargeable on the instrument of conveyance and not on the notional or speculative value of assets from which the purchaser derives no transferable or economic benefit. Where land situated in a buffer zone is classified and conveyed as agricultural land, and the purchaser is statutorily prohibited from cutting, felling or commercially exploiting naturally grown trees such as sagwan, saj, etc., such trees do not constitute a separable or independently transferable property interest. In the absence of any right of enjoyment, usufruct or commercial exploitation, the trees form an inseparable part of the land and cannot be treated as a distinct subject matter of conveyance for the purpose of levy of stamp duty. Stamp duty can be levied on trees separately only where the instrument of sale specifically transfers ownership or cutting rights in respect of such trees, or where the purchaser acquires an enforceable economic benefit therein. Merely because trees exist on the land does not justify an additional levy, particularly when statutory restrictions negate any economic value to the purchaser. Therefore, in respect of land purchased in 2020, where stamp duty has already been paid treating the property as agricultural land and no independent rights over the trees were conveyed or capable of being exercised, no separate stamp duty on the trees is legally payable.
