According to a Spanish court filing that emerged on Tuesday, Mourinho is unlikely to spend any time in prison despite pleading guilty to the offence.
This due to Laws in Spain usually not enforcing sentences of less than two years.
The Portuguese tactician was accused of owing Spanish tax authorities approximately €3.3 million (R50m) in unpaid tax.
In addition to the suspended sentence, he will pay a reported €2m (R30.5m) in fines.
The offences related to undeclared income around image rights while he was in charge of European champions Real Madrid between 2011 and 2012.
