The book offers an accessible introduction to accounting in non-profit organizations, even for those without prior commercial knowledge, covering the basics of club taxation and the annual tax return. Starting from simple entries in balance sheet accounts, it systematically presents all important booking cases, from expense and income entries to payroll entries. A tax and accounting lexicon, which lists booking entries and the tax treatment of business transactions for all important business events, completes the systematic presentation and serves as a reference. The included DVD contains two club management and accounting programs in two fully functional 4-week trial versions: "QuickVerein Plus" and "redmark club management." Content: The tax-related activities of non-profit corporations and important taxes in clubs.
