Real Madrid's Cristiano Ronaldo accused of $16.4m tax evasion

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 32-year-old -- the world's highest-paid sports star according to Forbes -- has been charged with four crimes against the public treasury.

The statement said the Portugese 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.

CNN Sport has contacted Gestifute, the agency representing the Portugal captain, for comment and also Real Madrid.

In 2016, Barcelona's Lionel Messi, who for the last decade has vied with Ronaldo for the title of world's best footballer, was fined $2.3m for defrauding the Spanish tax authorities.

The Argentine, 29, had also received a 21-month jail sentence but avoided prison as it was the forward's first offense.

According to Forbes, Ronaldo has earned $93m over the last 12 months, with his salary accounting for $58m and endorsements $35m.

The Real star -- his club's all-time leading scorer -- has also enjoyed a stellar 12 months on the field, guiding Portugal to Euro 2016 success last summer and helping his club win the Spanish league and Champions League in the 2016/17 season.
