sis to qualify for sss maternity benefit kailangan may non stop contribution ka po ng 3 consecutive quarter.. example January, February,March for 1st quarter April,May,June for 2nd quarter July,August,September for 3rd quarter then tsaka mo po i file yon sa sss office. Pero kahit isang beses nag skip ka hndi ka na qualified kase di mo naman pwede hulugan yung namiss mo na. Hope it helps! ☺️
