How is deferred tax accounted for under ASC 740?

Deferred tax assets (DTAs) and deferred tax liabilities (DTLs) are recognized for temporary differences between book and tax bases of assets and liabilities, as well as for loss and credit carryforwards. DTAs are reduced by a valuation allowance when realization is not more likely than not. When management intends to use a tax-planning strategy to support DTA realizability, that strategy must be primarily within management's control (ASC 740-10-30-20). - Recognition of temporary differences: A temporary difference arises whenever the book basis of an asset or liability differs from its tax basis. Common examples include accelerated tax depreciation, warranty accruals, loan origination fees recognized over the life of a loan for book purposes but at receipt for tax purposes, and deferred revenue. DTLs are recognized for differences that will produce taxable amounts in future periods; DTAs are recognized for differences that will produce deductible amounts in future periods.

How do Section 382 ownership change limitations reduce NOL carryforwards, and when must a company evaluate applicability?

- Measurement at enacted rates: DTAs and DTLs are measured using the enacted tax rate expected to apply in the period each temporary difference reverses. Rate changes — such as those introduced by major tax legislation — require remeasurement of existing deferred tax balances, with the resulting adjustment flowing through the income statement in the period of enactment. Reclassification of stranded tax effects from accumulated other comprehensive income to retained earnings may also be required under certain elections (ASC 220-10-50-3). - Valuation allowance: A valuation allowance is required against a DTA when, based on the weight of available evidence, it is more likely than not (greater than 50%) that some or all of the asset will not be realized. Negative evidence — such as cumulative losses in recent years or projected near-term losses — carries significant weight. Positive evidence — such as strong earnings history, reversing taxable temporary differences, or viable tax-planning strategies — can offset negative evidence. Tax-planning strategies considered in this analysis must meet the control requirements described in ASC 740-10-30-20.

What positive and negative evidence should factor into the valuation allowance judgment, and how do recent losses weigh against forward projections?

- Classification: All deferred tax assets and liabilities are classified as noncurrent on the balance sheet. DTAs and DTLs arising within the same tax jurisdiction are offset and presented as a single net noncurrent amount. DTAs and DTLs in different jurisdictions are not offset against each other. - Intraperiod tax allocation: Total income tax expense for a period is allocated among continuing operations, discontinued operations, other comprehensive income, and equity, ensuring each component reflects its appropriate share of the tax provision.

How should a company allocate deferred taxes between OCI and net income for unrealized gains/losses on investment securities?

- Using future or expected rates instead of enacted rates: Only rates enacted into law at the balance sheet date may be used to measure deferred taxes. Anticipated legislation does not qualify. - Inadequate valuation allowance analysis: Insufficient documentation of the positive and negative evidence weighed, particularly when a company has a history of cumulative losses, is a frequent audit finding. - Ignoring tax-planning strategies: Failing to consider legitimate, feasible tax-planning strategies may lead to an overstated valuation allowance — but strategies must satisfy the management-control threshold under ASC 740-10-30-20. - Incorrect jurisdiction netting: Offsetting DTAs and DTLs across different tax jurisdictions overstates net deferred tax positions. - Missing stranded tax effects: After major tax law changes, entities must evaluate whether income tax effects stranded in accumulated other comprehensive income require disclosure or reclassification (ASC 220-10-50-3). - Business combination deferred taxes: Deferred taxes arising in a business combination follow specific recognition and measurement rules and interact with goodwill — a commonly misapplied area. - ASC 740-10-30-20 — Establishes the requirement that tax-planning strategies used to support DTA realizability must be primarily within management's control; governs how such strategies factor into the valuation allowance assessment. - ASC 220-10-50-3 — Addresses disclosure requirements for entities that do not elect to reclassify income tax effects of major tax law changes (such as the Tax Cuts and Jobs Act) from accumulated other comprehensive income to retained earnings.
