The BBC reported the race had been under threat after a court ruled noise levels exceeded the legal limit and needed to be cut.
But it will now be run on 10 September after the regional council allowed a 30-day exemption to the ruling.
Monza has hosted every Italian Grand Prix since 1950 with the exception of 1980 when the race moved to Imola.
The circuit is co-owned by the municipalities of Monza and the nearby city of Milan.
