Besieged ex-billionaire Nathan Tinkler falls foul of Queensland taxman over unpaid payroll tax One-time billionaire Nathan Tinkler has come to the attention of the Queensland taxman over unpaid payroll tax. EMBATTLED ex-billionaire Nathan Tinkler is in fresh financial turmoil, this time with Queensland's taxman. The Commissioner of State Revenue has launched Supreme Court action against five key Brisbane-based Tinkler companies claiming almost $260,000 in unpaid payroll tax. Commissioner David Smith launched the action on October 3 seeking the winding up of Tinkler Group Holdings Pty Ltd, Hunter Ports Pty Ltd, Queen St Capital Pty Ltd, Thoroughbred Administration Pty Ltd and Tinkler Group Aviation Pty Ltd. It was the latest blow for the young mining tycoon, Newcastle Knights NRL team owner and racehorse breeder after he slipped off the BRW Rich List after his one-time $1.13 billion fortune plummeted, with assets including his private jet and mining shares seized by receivers, companies liquidated and hundreds of thoroughbred horses sold off. But in keeping with Mr Tinkler's new-found reputation as a desperate late-payer, he appears to have staved off a mass wipe-out of his Queensland companies by coming to a partial settlement with Mr Smith. "Four of the matters have now been dealt with to the satisfaction of the Commissioner and have been withdrawn," a State Government spokesman said. One matter is ongoing and, unless resolved before, will be subject to a further hearing before the court in November. It is not clear how much Mr Tinkler still owes in payroll tax. A spokesman for the businessman said he believed the debt had been settled in full. Earlier this year, Mr Tinkler put his Patinack Farm racing empire - including a showpiece stud at Canungra in the Gold Coast hinterland - up for sale, but a buyer is yet to be found. Thoroughbred Administration Pty Ltd was formed to run Patinack Farm after another company collapsed late last year. Former Australian Kangaroos, Queensland Origin, Brisbane Broncos and St George Illawarra Dragons coach Wayne Bennett announced last month he was staying on as Knights mentor despite Tinkler's shaky financial state.
