Auditor-General Pisit Leelawachiropas said at a seminar on tackling corruption in Thailand that the Revenue Department has to perform its duty on tax collection. 
He said OAG would petition the National Anti-Corruption Commission if the department failed to pursue this tax case before the March 31 deadline. 
Earlier, the Revenue Department said it could not collect the taxes under Article 61 due to the expiry of statute of limitations. 
According to the OAG, former premier Thaksin Shinawatra is liable to back-taxes on the sale of Shin Corp shares to Temasek Group of Singapore, even though he used his children as nominees in holding the shares while serving as prime minister.

OAG threatens petition against Revenue Dept if no Shin Corp tax collected

The Office of the Auditor-General (OAG) has insisted that the Revenue Department is empowered to collect income tax on the 2006 sale of Shin Corp shares in accordance with Article 61 of the Revenue Code which says that persons whose names appear in asset ownership document are subject to tax.
