Sakhanovich made her international debut in the 2013–2014 season. After placing fourth at the ISU Junior Grand Prix in Slovakia, she then won the gold medal in her next JGP event in Estonia. Her results qualified her for the JGP Final in Fukuoka, Japan, where she won the silver medal behind teammate Maria Sotskova. Sakhanovich finished sixth on the senior level at the Russian Championships and went on to win the junior national title ahead of Sotskova. She placed second in both segments at the 2014 World Junior Championships and was awarded the silver medal. Gold went to Elena Radionova and bronze to Evgenia Medvedeva, producing Russia's second consecutive sweep of the World Junior ladies' podium. She experienced pain in her right foot during the event but her condition improved after a month's rest.
