This document discusses the general principles of taxation according to a lecture on income taxation. It defines taxation as the means by which a government raises income to fund its necessary expenses. The primary purpose of taxation is to provide funds to promote citizens' welfare and finance government activities. Other purposes include strengthening industries, protecting local industries, and reducing inequality. The principles discuss the theory that government needs revenue and has the right to tax citizens in return for protection. A sound tax system should be fiscally adequate, impose equal burdens based on ability to pay, and be administratively feasible. The document also outlines constitutional and inherent limitations on taxation powers.
