BP have revealed that they are chasing a tax credit of around $9.7 billion (£6.3bn).
The oil giants who have recently found themselves having to pay out billions as a result of the Gulf of Mexico spill and are now hoping to reclaim some of that amount from the US government.
A income statement from the BP group shows a pre-tax charge of around $32.2bn which is presumably linked to the oil spill and a tax credit of $9.79bn.
According to US law BP can offset a proportion of its losses against US tax but given the current relationships between the two it could make for a frosty reception.
Current estimates on the costs of the disaster amount to around $4,300 per barrel spilt which BP will have to pay, on top of any civil or private payouts they need to make.
