Her father Prince Andrew's website states that his eldest daughter "works full time in finance" as well as listing her various charity projects.
The Princess, who is sixth in line to the throne, recently celebrated her 25th birthday at her father's home near Windsor Castle. Her star-studded guest list was rumoured to have included Prince Harry, Pippa Middleton, Robbie Williams and Sir Richard Branson.
Beatrice is reportedly in Sotogrande, Spain on holiday with her parents at the moment.
Earlier this summer she visited the South of France with her long-term financier boyfriend Dave Clark. They caught up with Hollywood friends Ashton Kutcher and his girlfriend Mila Kunis while in St Tropez.
The Princess also visited Venice with her younger sister Princess Eugenie and their mother Sarah, Duchess of York.
