AI Overview
Unearned income is money received from sources other than active employment or services rendered, such as investment income (dividends, interest, royalties), rental income, inheritances, gifts, and certain benefits or pensions. In contrast, earned income comes from wages and salaries for direct work. While unearned income is generally not subject to payroll taxes like Social Security or Medicare, it is typically taxable and must be reported on tax returns.
