Tara Fitzgerald was born in Sussex, England. Her mother, Sarah Fitzgerald, is Irish, and her father, Michael Callaby, was Italian. Shortly after her birth, her family moved to Freeport, in the Bahamas where her grandfather, David Fitzgerald, was a well-established lawyer. Her sister, Arabella Fitzgerald, was born there, but the family returned to London when Tara was three. Her mother and father separated when she was four-years-old and, along with her mother and sister, Tara moved in with her uncle and Aunt Caroline. Her mother married the Irish actor Norman Rodway when Tara was age 6, and the birth of her half-sister, Bianca Rodway, followed shortly thereafter. Rodway and Sarah Fitzgerald separated when Tara was seven.　　Tara's formative years were spent moving around - a lifestyle that saw her attending five primary schools while living in a variety of locations which included Glasgow, Dublin, and Stratford-upon-Avon. Eventually, Sarah and her three daughters returned to South London, but she left at the age of 16 after passing her"O" level examinations, now known as the GCSE (General Certificate of Secondary Education) exams. Her reason for taking a break from the educational process was that she was not allowed to pursue her goal of attending drama school. Tara had auditioned for RADA and the Guildhall, but she was unable to secure a placement. She now recognizes that, at age 17, she really had not been ready.　　Tara spent the next two years working her way around Europe as a waitress, an experience that provided her with an improved perspective. When she returned to London and decided to audition for a place at the Drama Centre, she was accepted immediately. Her training at the Drama Centre leaned heavily toward method acting which she recalls was like one long therapy session of breaking down the ego, and then rebuilding it. (Other well-known actors who trained at the Drama Centre include Anthony Hopkins, Colin Firth, Simon Callow and Pierce Brosnan).
