According to Commerce Ministry estimates, if the loss to the exchequer is Rs 90,000 crore, then the export profit of units in the 150 SEZs that have already been cleared should be around Rs 4 lakh crore.
Assuming that the units have 20% profits then their combined economic activity would be close to Rs 20 lakh crore.
The Commerce Ministry said the government would also gain from sale of goods from SEZs to domestic tariff area as import duties would have to paid. These import duties would be higher as they would be on finished products and not on raw material that the units will import duty-free.
It defended tax concessions to exports by units in SEZs saying that the units in domestic tariff area were already getting such concessions. On incentives for developers of SEZ, the officials said that developers of infrastructure were already getting tax concessions.
