The defender began his career 2004 with Roeselare with which he enjoyed promotion to the Belgian Pro League. After two more seasons with Roeselare at the highest level, he had a short spell at Mons before moving abroad to MVV.

After two more seasons with Leuven in the second division, he was again able to take part in promotion festivities as Leuven became second division champions in 2011. Following the 2011-12 season, he moved to Sint-Truiden, but during the 2012-13 season he was deemed surplus. In February 2013 Sint-Truiden agreed to terminate his contract to allow Annys to move as a free agent to Hjørring. After half a season at Hjørring, Annys returned to Belgium as he signed with Westerlo.
