Neymar is also understood to have omitted advertising services, image rights and other contracts signed between 2011 and 2013 from his tax returns.
Brazilian judge Carlos Muta has accused Neymar of “omitting sources of income from abroad” as was quoted by the Guardian.
However, Iagaro Jung Martins, an auditor with Brazil’s federal tax agency, said that Neymar isn’t likely to go to jail if he pays what he owes.
The judge froze three times that amount for security reasons and to cover potential interest and fines, according to a judicial order explaining the seizure.
The Brazilian player is accused of not paying £10m in taxes between 2011 and 2013.
The action covers property and vehicles and is a preventive measure to stop the player from selling assets before the case is settled.
Neymar’s parents told the Brazilian newspaper Folha de S. Paulo that Neymar had not evaded taxes and was not a partner in the businesses named in the court decision.
Neymar will still be able to access bank accounts and liquid assets during the case.
But Neymar’s comments may indicate that United are continuing to track the Barcelona star, with a view to a further opporunity to join the Old Trafford club in forthcoming transfer windows.
While it’s not clear how exactly the misstatement occurred, the assets seized included three companies listed in the names of Neymar and his father.
Barcelona striker Neymar has had assets of more than £31m frozen for alleged tax evasion.
Neymar’s former club Santos was unhappy with how the transfer fee was divided up.
Then Barcelona president Sandro Rosell said the player cost €57.1 million (S$91 million) but the deal was shrouded in secrecy.
