Renting of immovable property- Service Tax

Agricultural Market Committee (Krashi Mandi Samiti), besides
collection of mandi fee, provides godowns /shops to dealers/ commission agents
on lease basis for storage and trading of agricultural produce. Leases are of two
types one for 99 years & entire lease amount collects in one time and
second is yearly basis where lease amount collects annually. In 99 years lease, amount consists of Value of Land, Cost of Construction and one time lease
amount for 99 years. My question is (1) whether both types of leasing liable to
tax or lease for 99 years (like sale) will not covered? (2) if both
types of lease liable to tax, than on which amount? (3) If the gross receipts from leasing
activity are below Rs.10 lacs per year, Market committee is liable for
registration and payment of service tax.
