Tofting is alleged to have punched and headbutted cook Per Thoestesen in front of 200 guests at a welcome home dinner for the World Cup squad.
The 32-year-old was released after denying the charges when questioned by police.
Copenhagen police confirmed on Monday that he had been charged with assault, which carries a maximum sentence of 18 months imprisonment.
Tofting had announced his retirement from international football in the wake of Denmark's 3-0 second-round defeat by England.
The former Hamburg midfielder had played an important part in Denmark's success in the group stages, where they beat holders France 2-0 to top Group A.
"I wanted to make the decision myself and not let the coach make it for me," Tofting said at the time.
He became the fourth member of the squad to retire from the international game, following Jan Heintze, Brian Steen Nielsen and reserve goalkeeper Peter Kjaer in stepping down.
