Fiorentina chief Mario Cognini says they're delighted to be debt free.
The Viola went bankrupt in 2001 and dropped down to Serie C2, where a new club was born under the tutelage of the Della Valle brothers.
A study from credit agency Standard & Poor's also found Fiorentina are the financially healthiest club in Italy.
"This means we are on the right track," Cognini told La Repubblica newspaper.
"Two years ago we began a new journey to develop the club, but there is a lot of work still to be done. Fiorentina are at the top in terms of solvency and that is possible because on the one hand the revenue allows us to cover current expenses and on the other our owners put in no less than 15m per year to keep the books balanced.
"That means we have not needed to apply for loans and therefore have zero debt."
