Under Spanish law, prison sentences under two years can be served on probation.
Messi and his father were found guilty of three counts of tax fraud by a court in Barcelona on Wednesday.
In June, a court heard that the pair defrauded around €4million (£3.4m) over three years from the Spanish authorities. Tax havens in Uruguay and Belize were used to shield money made off the back of Messi’s image.
The court ordered Messi to repay €1.4m (£1.7), and his father €1.2 (£1.27), after concluding that while Jorge Messi was primarily responsible, Messi knew enough about his finances to also be held accountable.
