The name is from the word "Tao" or "tawo" meaning the people, and the word "Taon" or "tawon" meaning to evacuate to a higher ground. The early settlers in this place were always bothered by the overflowing Inopacan River that forced them to move to nearby higher grounds. Thus, "Tao-taon" means the place where the people kept on moving to a higher ground when the Inopacan river overflowed. The old river bed that traversed across this place is now dried up and had been cultivated to become at present an open field farm, while a creek still exist on portion of the river bed that approaches to the sea, where nipa palms and mangrove trees now abound. The river changed its course to its present channel and is being prevented from returning to its old route by concrete dikes.
