However, with the amendment in the definition of royalties in year 2012 On a cogent reading of definition of 'royalty' with the recently introduced amendments, it appears that the payment made to the telecom company for data transmission by leased line would fall within the definition of 'royalty' under section 9(1)(vi) of the Act and thus liable for TDS under section 194-J of the Act.
