An amount of earned income that is payable at a later date. Most deferred-compensation plans allow the wage earner to defer tax now so that the funds can be withdrawn and taxed at some point in the future.
Explained further: The most common form of deferred compensation is a retirement plan. Deferring income allows the earner to use the income later in life when they have a lower tax rate. Other examples include pension plans and stock-option plans.
