Montserrat Caballé, one of the world's best-known sopranos, has been charged with tax evasion for failing to declare 500,000 euros (about $700,000) of concert income.
The 81-year-old singer is due to appear in a Catalonian court on May 9 for not declaring a bank account registered in Andorra, a tiny principality bordered by Spain and France. A court document reviewed by Reuters alleges that the singer gave a series of lucrative concerts in Spain, Germany, Switzerland, Italy and Russia in 2010, which brought her more than 2 million euros that tax year.
Caballé's opera career stretched over some 50 years. She became famous for her bel canto roles at major opera houses although the general public may know her best from an appearance with the late Freddie Mercury during the closing ceremonies of the 1992 Olympics in her home town of Barcelona.
Spain has been cracking down on tax evasion as it attempts to fill a large public deficit amassed during its prolonged economic crisis. Caballé has not responded to several media requests for comment on the charges.
