Ms Ronan, who celebrated her 21st birthday in April, came to prominence eight years ago arising from her Oscar-nominated role as Briony Tallis in the screen adaptation of Ian McEwan’s novel, Atonement.
Later this year, the Carlow woman’s meteoric rise in the movie industry will hit new heights when the Nick Hornby-scripted movie of the Colm Toibín novel Brooklyn hits cinema screens.
New accounts filed with the Companies Office show that Ms Ronan’s Slaney Productions Ltd recorded profits of €111,677 in its first year in operation.
The firm had a cash pile of €36,628 and was owed €162,224 by debtors.
Ms Ronan has already spent some of her largesse on her own home in Howth, Co Dublin, when she paid out €334,000 for a home there in August 2013.
Shortly after the planned November release of Brooklyn, Ms Ronan will be busy preparing for her February 2016 Broadway debut where she is to play the role of Abigail Williams in a production of Arthur Miller’s The Crucible.
Slaney Productions Ltd, a nod to Ms Ronan’s Carlow heritage, was only incorporated on January 1, 2014.
Ms Ronan’s career has been carefully managed by her father Paul, a former actor.
