The total outstanding tax demand payable to exchequer has risen by nearly 45% to Rs 10.7 lakh crore in the April-December period of the current fiscal from the FY16 level, minister of state for finance Shiv Pratap Shukla said in a written reply in Parliament on Tuesday. The outstanding demand includes both direct and indirect taxes. The reply, however, cited a confidentiality clause in I-T Act to a deny information on outstanding liability of specific taxpayers in the corporate sector. “General disclosure of tax information of specific taxpayers is prohibited under section 138 of the I-T Act,” the minister said.
