About Maaser Kesafim
Maaser kesafim (literally "a tithe of money") is the Jewish practice of giving 10% of one's income to tzedakah. Its biblical source is Genesis 28:22 ("of all that You give me, I will surely give a tenth") and reinforced by the Talmud in Ketubot 50a.
Most opinions calculate maaser on net income — after federal/state taxes and necessary business expenses. Gifts and inheritances are debated (Igrot Moshe: yes for inherited money; many poskim: optional for gifts under a certain size).
The Shulchan Aruch (Yoreh Deah 249:1) describes three tiers: 10% (typical), 20% / chomesh (generous), and below 10% (minimal — to be avoided where possible). Maimonides' eight levels of tzedakah famously rank anonymous giving and helping someone become self-sufficient as the highest forms.
Halachic opinions differ on what counts toward maaser and which recipients qualify. Consult your rabbi or posek for personal psak. Charitable contributions to a US 501(c)(3) Jewish charity are tax-deductible on Schedule A if you itemize.
