Brindisi prosecutors said he was also accused of "aggravated personal injury and crimes committed to the prejudice of a young foreign woman".
The ANSA and AGI agencies also report Mr Haggis has denied the allegations via his lawyer, Michele Laforgia.
The BBC has contacted Mr Haggis's representatives and the prosecutors.
"Make enquiries as soon as possible, I am totally innocent," the Canadian filmmaker said, according to the agencies, who quoted Laforgia.
