Tax effect of an accounting change or error

Working definition

The supported current and deferred income-tax consequences of an accounting change or error, allocated to the same periods and statement components as the underlying item when applicable.

Also calledTransition tax effect · Restatement tax effect

A pretax adjustment does not carry an automatic tax rate. The tax file identifies jurisdiction, enacted rate, tax basis, deductibility or taxability, current and deferred components, valuation-allowance implications, uncertain positions, and the statement component receiving the underlying adjustment.

For a bounded classroom schedule, a supplied enacted rate may generate the direct deferred-tax effect. The result still ties by period to opening equity and comparative income. Real cases stop for tax specialists when law, rates, basis, attributes, or recognition conclusions are incomplete.

Follow the underlying item

ASC 250-10-45-8 includes related income-tax effects among the direct effects of a retrospective principle change. The tax result still depends on Topic 740 facts rather than a default percentage.

ASC 740-20-45-2 identifies the statement components among which annual tax expense or benefit is allocated. Suppose an opening inventory adjustment is $100,000 and supplied facts establish a 25 percent deferred-tax effect. The bridge increases inventory $100,000, increases the deferred tax liability $25,000, and increases opening equity $75,000. If tax basis, rate, jurisdiction, or recognition differs, stop and obtain the supported tax schedule. This concept does not decide those tax inputs.
