This document discusses factors that contribute to tax evasion and the differences between tax evasion and avoidance. It identifies high tax burdens, low incomes, weak government systems like corruption, and underground markets as factors that increase tax evasion. Tax morale and loopholes in tax deductions can also enable evasion. Tax avoidance uses legal methods to reduce taxes, while evasion intentionally violates tax laws. Penalties for evasion include fines, imprisonment, and additional taxes owed depending on the specific offense of incorrect returns, willful evasion, or understatement of taxes. Case studies are also referenced to illustrate how these laws have been applied.
