The Australian Tax Office (ATO) is chasing Crown Resorts down with a $250 million tax bill from its pre-GFC foray into the US casino market.

Crown has received an amended tax assessments from the ATO, regarding income tax paid for the financial years ending June 30, 2009 to June 30, 2014 for its investment in Nevada-based casino operator Cannery Casino Resorts (CCR).

ATO is seeking $250 million from Crown plus an additional notice of penalties to the amount of about $112 million, bringing the total to $362 million.

Crown disputes the amended assessments and said that is intends “to pursue all available avenues of objection including, if necessary, court proceedings”
