The noun UNEARNED INCOME has 2 senses: 1. personal income that you did not earn (e.g., dividends or interest or rent income). 2. (accounting) income received but not yet earned (usually considered a current liability on a company's balance sheet). Familiarity information: UNEARNED INCOME used as a noun is rare.
The earned income limits average around half of that for a single taxpayer and unearned income limits are much smaller. For example, children and other dependents who had unearned income of more than $950 in 2012 were required to file taxes.
