An International Chamber of Commerce (ICC) tribunal ruled on 30 September that Ghana’s $196.5 million tax assessment on Tullow Oil did not breach the company’s petroleum agreements. Ghana’s Revenue Authority puts Tullow’s total liability, including penalties and interest, at $393 million; the London-listed firm’s shares fell sharply. The dispute concerned tax on insurance payouts Tullow received between 2016 and 2019. The ruling strengthens Ghana’s hand with oil companies but hits a producer that relies on Ghanaian cash flow to service its debts. The tax authority has promised a settlement that will not disrupt operations, while Tullow still faces another Ghanaian arbitration and a tax claim in Kenya.
