Barcelona star Neymar and his father have been ordered by court in Brazil court to pay €100,000 as a fine for unpaid taxes during 2007-08, according to a report.
Neymar is expected to appeal, his lawyers told Brazil site UOL on Wednesday.
The fine corresponds to back-tax payments that Neymar and is father made per order of the Brazilian IRS back in 2012. However, Neymar Sr. had appealed the fine in 2014 and the appeal was pending.
Now the federal court in Sao Paulo has determined that the initial fine was correct and ordered Neymar and his father to pay it.
The court order is part of a larger, ongoing dispute over the taxes of the Brazil and former Santos forward that is being played out in courts in Brazil and Spain.
The Brazil team captain moved in 2013 from Brazilian club Santos to Spain's Barcelona in a transfer whose payment is also under investigation by Spanish tax authorities.
A Brazilian court last fall froze assets for Neymar, his family and related businesses valued at 188.8 million Brazilian reals ($48 million, €42 million).
The Sao Paulo federal court have said that the 23-year-old is alleged to have evaded 63 million reals in Brazil taxes (almost $16m or €14m) between 2011 and 2013.
Spanish court also claims that Barcelona club president Josep Bartomeu and his predecessor Sandro Rosell evaded millions in taxes after signing Neymar from Santos. Neymar and his father have been ordered to testify in Spanish court in that case on Feb. 2.
