All five people accused of conspiring in what one described as the "Ben Hur" of tax scams and another called the "biggest tax fraud in Australia's history" have now been found guilty after a marathon trial.

The last conspirator in the Plutus Payroll tax scheme trial still awaiting the jury's verdict learned their fate on Tuesday, almost 11 months after the trial began in the NSW Supreme Court.
