The department has initiated orders to take away $104 million dividend due from its stake in the subsidiary Cairn India, known as Vedanta Ltd now.
The authorities have adjusted tax refunds of Rs. 1,500cr to the retrospective tax.
The tussle between Cairn Energy and I-T department
What triggered the I-T move?
In March this year, the I-T department had sent Cairn Energy a notice informing them of retrospective tax amounting to Rs. 10,247 crore payable to the department.
The I-T authorities set 15 June, 2017 as the deadline for making the payment.
The British company raised the issue before an international arbitration panel, which refused to entertain its pleas against the I-T move.
