New Delhi, Aug. 29 (PTI): The income tax department has slapped a Rs 32,320-crore demand in tax, interest and penalty on Hong Kong-based Hutchison for alleged capital gains it made on the $11-billion sale of its mobile business in India to UK's Vodafone Group in 2007.

In a filing to the Hong Kong stock exchange, billionaire Li Ka-shing's CK Hutchison Holdings Ltd said its unit, Hutchison Telecommunications International Ltd (HTIL) had been served with a tax demand of about Rs 7,900 crore, Rs 16,430 crore of interest and another Rs 7,900 crore in penalty.

The CK Hutchison unit continues to dispute the validity of those taxes, it said.

This is the first time a tax demand on the Hong Kong firm is being raised. So far, the Indian government had been pursuing the tax from Vodafone.

Vodafone was initially slapped with a Rs 7,990-crore tax demand for not withholding tax from payments it made to Hutchison. The outstanding after including interest and penalty runs over Rs 20,000 crore. It challenged the levy and the Supreme Court in January 2012 ruled that the company was not liable to pay any tax over the acquisition of assets in India from Hutchison.

Thereafter, the government in May 2012 amended the tax laws with retrospective effect and claimed taxes.

Vodafone has disputed such levy and the matter is before an international arbitration panel.

HTIL, an indirect wholly owned subsidiary of CK Hutchison Holdings Ltd, received from the tax department a draft assessment order dated November 24, 2016 alleging gains made on the sale of its entire 67 per cent in the India business to Vodafone.

"HTIL received on February 13, 2017 from income tax an assessment order dated January 25, 2017 in respect of tax of approximately Rs 7,900 crore on capital gains" in connection with the 2007 deal plus aggregate interest of approximately Rs 16,430 crore," the filing said.

Further, "HTIL received on August 9, 2017 from the income tax authorities a penalty order dated July 3, 2017 for a penalty of approximately Rs 7,900 crore", it added.

The taxes cannot be validly imposed on HTIL, the filing said, adding that the income tax order was in violation of the principles of international law.
