Latest Answer: Right Hitesh........the Urban Development Department has finally cleared the proposal yesterday to increase stamp duty by 1% in Metro Rail corridor. The corridor is the area lying within 500 metres on both sides of the Metro track. The duty will now be 7.5% instead of 6.5%. The 1% registration charge (maximum Rs.30000) will remain unchanged. The stamp duty in the city except the area under Metro corridor will remain at 6.5%.
