Temporary difference

Working definition

A difference between a book carrying amount and tax basis, or an equivalent future consequence, that will produce taxable or deductible amounts when the item is recovered or settled.

A temporary difference links a reported amount with the future tax consequence of recovering an asset or settling a liability. Some temporary differences arise from deferred tax deductions or income without a directly paired book asset or liability. Classify the future amount as taxable or deductible and schedule when it reverses.

Map origin and reversal

ASC 740-10-25-22 gathers the timing differences and income-tax-balance-sheet differences described in the surrounding guidance under the temporary-difference term.

Suppose accelerated tax depreciation creates a $120,000 current deduction beyond book depreciation. If the opening taxable difference was $220,000, the ending difference becomes $340,000 before other changes. Current tax uses the $120,000 period adjustment; deferred tax measures the supported $340,000 ending future amount. “Temporary” does not mean next year. Preserve origin, reversal calendar, tax character, jurisdiction, enacted rate, and evidence. A schedule tie does not establish tax basis or a recognition exception.
