The sale, originally scheduled to take place last year, is now planned for the coming weeks following the signing of the relevant decrees by the finance and treasury ministers, the Finance Ministry said.
The rules for participating in the auction are still being finalised and will be announced shortly.
On the block is not just the 75,000-seater stadium created for the 1960 Olympics and now home to Serie A soccer teams Roma and Lazio, but swimming pools and the clay tennis courts used for the Italian Open.
Interspersed with neo-classical sculptures of athletes and with a massive 17-metre marble monolith at its entry, the Foro Italico complex was built under Mussolini in 1931.
While the tennis tournament creates two weeks of activity in May each year, the complex is generally only busy once a week when either Lazio or Roma play at home.
"If the Metropolitan (opera house) in New York was only open for an hour and a half a week, it would have closed down 50 years ago," Finance Minister Ottaviano Del Turco said.
When the sale was first announced in April last year, at least five consortia were said to be interested in bidding.
Lazio and Roma , both listed on the Milan stock exchange, are said to be interested in acquiring the complex, which is estimated to be worth around 1.0 trillion lire ($465 million).

Italy has moved closer to selling Rome's Foro Italico sports complex, announcing it would auction one of the great projects of Fascist dictator Benito Mussolini "very shortly".
