To Gain and to Give: Hilchot Tzedakah, Day 19

Ma’aser is given from one’s earnings. Earnings are defined as the money one has after income tax is taken. For example, if one earns $75,000 a year and pays $7,000 in income tax, they take ma’aser from $68,000, and give $6,800 to tzedakah (to be continued).
