An asset that is used to reduce the amount of tax that a company will have to pay in a later tax period. It is often associated with a loss carryover, and is used as a future write-off if the next tax period is expected to produce positive earnings. The asset is kept on the balance sheet. For example, a deferred tax asset of $100,000 from the previous year could be applied to before-tax income of $250,000 this year, resulting in taxable income of $150,000 ($250,000 - $100,000).
