South Sudan Vice President for Economic Cluster Dr. James Wani Igga says more than 400 companies working in the oil sector have not paid taxes since independence in 2011, amounting to a loss of more than $4 billion in revenue.

VP Igga spoke at the launch of the resumption of oil production in Unity State's Tharjiath oilfield on Monday after more than eight years of shutdown.

He said the companies have been operating in total disregard to the tax regulations for about 10 years.  

“We examined only 40 of them out of those 500. Most of them have never paid Personal Income Tax (PIT) since independence 2011. From this 40 we uncovered unpaid PIT amounting to $1.5 billion just for 10 years. This is something that is supposed to go the coffers of the Ministry of Finance," Dr. Igga said. "This is not including the sum of $3.3 billion due to the country from the actual oil companies as arrears.”

Dr. Igga stressed that this impunity is the reason why the country continues to suffer from a financial crisis despite oil production.

"Why do you think South Sudan is suffering from the financial crisis? We produce 116,000 barrels per day, and the price of oil is currently more than 60 US dollars, and we should not suffer from the financial crisis because we have diverse sources of income,' he added.

The Vice President said the situation must change, adding that residents in the oil-producing areas must also receive their share for development.

The ministerial economic cluster started assessing the performance of the oil and petroleum sector last month.
