Definition of Income for Tax Purposes. The Internal Revenue Code requires you to pay taxes on most types of income. Even some non-monetary compensation meets the definition of income for tax purposes. Certain types of income are exempt from income tax or qualify to have the tax deferred to a later date. The tax code is complex and contains numerous exceptions to every rule; consult with a tax professional for advice on your specific situation.
