Deferred tax asset realization evidence

Working definition

Positive and negative evidence used to assess whether deferred tax assets will be realized within jurisdictional, character, and expiration constraints.

Realization review asks whether recognized deductible differences and carryforwards will produce usable tax benefits. Match evidence to the same jurisdiction, tax character, and expiration period. Give greater weight to evidence that can be verified than to an unsupported forecast created to clear the allowance.

Weigh all available evidence

ASC 740-10-30-17 requires consideration of positive and negative evidence and notes that evidence can have different weight. ASC 740-10-30-18 connects realization to sufficient taxable income of the appropriate character.

A signed profitable backlog may support a forecast, while recent cumulative losses and repeated forecast misses provide contrary evidence. Reversing taxable temporary differences can be a separate source if their timing and character match. Record each item, its date, owner, relevance, and weight. The calculator can apply a supplied allowance conclusion, but it cannot forecast taxable income, approve a tax-planning strategy, or decide how persuasive the evidence is.

State the conclusion by asset source rather than describing the entity as profitable or unprofitable in the abstract.
