A tithe is a portion of income given to a church or charity, traditionally one tenth, which is 10%.

Do I tithe on gross or net income?

It is a personal choice: some tithe on gross income (before tax) and others on net (after tax). This tool supports both — pick the basis that fits your conviction.

Is my income kept private?
