Ronaldo has been summoned to a hearing next month into accusations of tax fraud - allegations his representatives have denied - and was reported to be so outraged over perceived unfair treatment by the Spanish authorities that he was considering leaving the country.
The 32-year-old, who is under contract until 2021, has been linked with a return to Manchester United but while Perez has spoken openly about the Portugal star's outrage, he has played down talk of a summer exit.
"He has a contract with Real Madrid and, when he stops playing at the Confederations Cup, we will talk," Perez said
"He's angry, that's for sure, because he is an honest person who fulfils his obligations.
"I have not talked to him but we are delighted that he is in Madrid. I think he will continue in Madrid."
Asked further about Ronaldo's tax affairs, Perez added: "We all have to fulfil our fiscal obligations. Madrid is not responsible for the players' declarations, but there has never been a concealment. Cristiano does not have to deny anything he has not said."
