Tax fraud involves deliberately underpaying taxes owed through dishonest means such as underreporting income, overstating deductions, or providing false information. Common methods of tax fraud include suppressing personal expenses, deliberately omitting income from business transactions, making false entries in books to hide unreported income or inflate expenses, and concealing receipt of income by not recording transactions. Large corporations may also commit tax fraud through practices like improper transfer pricing or window dressing financial reports. Individual tax fraud usually stems from rationalizations of high taxes and opportunities created by complex tax systems.
