I say, and with God's success: The Zakat al-Fitr is obligatory for everyone who possesses the nisab (minimum amount) that exempts them from zakat, which is 100 grams in excess of their basic needs such as housing, car, furniture, and others. Therefore, if someone does not have a financial surplus of this amount, Zakat al-Fitr is not obligatory upon them. In contrast, the regular zakat has its own nisab for those who possess it and must pay zakat on their wealth. And God knows best.
