"I confirm that a special fine of 150 percent was applied... requiring payment of 188,820,129,25 reals ($47.3 million), of which 63,591,796 relate to income tax and the rest to fines and interest, with regard to events that took place in the calendar years from 2011 to 2013," Judge Muta wrote.
The court ruling is another body blow to the reputation of Mr Neymar Junior, the figurehead of Brazil`s national team.
The 23-year-old is already battling fraud allegations in Spain stemming from the financial arrangements surrounding his move from Santos to Barcelona in 2013.
In June, Spain`s National Court admitted a lawsuit alleging "corruption and swindling" by Mr Neymar Junior, his father and Santos.
The case has been brought by a Brazilian investment fund, DIS, which owned part of the transfer rights for the player when he was at Santos.
