Story highlights Agency for Cristiano Ronaldo says he was not trying to evade Spanish taxes

Prosecutors accuse the Real Madrid star of defrauding authorities of $16.4 million in tax

(CNN) Real Madrid and Portugal star Cristiano Ronaldo has been accused by prosecutors in Spain of defrauding Spanish authorities of $16.4 million in tax between 2011 and 2014.

In a statement, the prosecutor's office said Ronaldo, a four-time Ballon d'Or winner, had used a "business structure" -- created in 2010 -- to hide the revenue generated by his image rights from the Spanish treasury, describing the breach as "voluntary" and "conscious."

The statement said the Portuguese became a Spanish tax resident in January 2010 and, in November 2011, opted to follow the Spanish tax regime that applies to foreigners working in the country.
