The former Italy international is one of five players who has been punished for his part in the match-fixing controversy after he originally proclaimed his innocence last month
While Mario Cassano, Stefano Ferrario, Carlo Gervasoni and Alessandro Zamperini have all been punished too.
The five players were under investigation for alleged sporting fraud relating to the Lazio matches against Genoa and Lecce at the end of the 2010-11 Serie A season and have now been found guilty by FIGC's disciplinary committee.
"In relation to the match between Lazio and Genoa, Gervasoni has been handed a two-month ban, Cassano a four-month suspension, Ferrario and Mauri are banned for six months and Zamperini receives a two-year ban," a statement on the FIGC website reads.
"Additionally, Lecce will be fined €20,000 (£17,487) and Lazio €40,000 (£34,933) in relation to the match between Lazio and Lecce.
"These are the decisions of the national disciplinary committee chaired by Sergio Artico in Cremona on Calcioscommesse."
FIGC's decision will come as a huge blow to Mauri following his comments earlier last month stating his innocence.
