What Is ASC 740? Accounting for Income Taxes

Accounting for income taxes is governed by specific standards within U.S. Generally Accepted Accounting Principles (U.S. GAAP). The primary guidance is Accounting Standards Codification (ASC) Topic 740, which provides the framework for how a company must account for and report the effects of income taxes on its financial statements.

The objective of ASC 740 is to recognize the amount of taxes currently payable or refundable and to account for future tax consequences of past events. This is done by recognizing deferred tax assets and liabilities, which represent the future tax effects of items treated differently for financial reporting versus tax purposes.

Core Components of the Tax Provision

The income tax provision on a company’s income statement is the total income tax expense for a reporting period, composed of two primary components: the current tax expense or benefit and the deferred tax expense or benefit.

The current tax expense or benefit is the amount of income taxes payable to or receivable from tax authorities for the current period. This calculation is based on the taxable income or loss for the year, determined by applying enacted tax laws and rates. It is the amount a company expects to report on its corporate income tax returns and includes taxes at the federal, state, and foreign levels.

The deferred tax expense or benefit arises from changes in a company’s deferred tax assets and liabilities during the period. These deferred accounts address the timing differences between when transactions are recognized for financial reporting versus tax purposes. This process matches the tax effects of transactions to the period in which the transactions are reported, a core principle of accrual accounting.

The calculation of deferred taxes depends on the distinction between temporary and permanent differences. A temporary difference is a discrepancy between the tax basis of an asset or liability and its carrying amount in the financial statements that will eventually reverse. For example, using accelerated depreciation for tax returns while using straight-line for financial statements creates a temporary difference.

Permanent differences are items that affect either book income or taxable income, but not both, and they never reverse. For instance, certain entertainment expenses are not deductible for tax purposes. This type of difference impacts only the current tax expense calculation and does not create a deferred tax item.

These temporary differences lead to recognizing either Deferred Tax Liabilities (DTLs) or Deferred Tax Assets (DTAs). A DTL is recorded when a temporary difference will result in future taxable amounts. The accelerated depreciation example creates a DTL because the company will have to pay more in taxes in the future to make up for the larger deductions it took in the early years of the asset’s life.

A DTA is recognized for temporary differences that will result in future deductible amounts or for tax credit carryforwards. For instance, if a company records a warranty reserve for expected future claims, this expense is recognized immediately on the books. However, for tax purposes, the deduction is often not allowed until the warranty claim is actually paid, creating a DTA that represents a future tax benefit.

The Valuation Allowance Assessment

After calculating its deferred tax assets (DTAs), a company must assess if it can realize their future value. A valuation allowance is a contra-asset account that reduces the carrying amount of DTAs to the amount that is “more likely than not” to be realized. This prevents companies from overstating assets with tax benefits that may not materialize.

The “more likely than not” standard means there must be a greater than 50 percent probability that the DTA will be realized. This assessment requires significant management judgment and must be performed for each tax-paying component in each tax jurisdiction.

To support the conclusion that a DTA is realizable, a company must identify sufficient future taxable income from four potential sources:

• Future reversal of existing taxable temporary differences, which create deferred tax liabilities (DTLs).
• Future taxable income, which involves developing projections of future profitability.
• Taxable income in prior carryback years, if permitted by the jurisdiction’s tax law.
• Implementation of specific tax-planning strategies that are feasible and within the company’s control.

The assessment involves weighing all available positive and negative evidence. Negative evidence might include a history of recent operating losses, an expectation of future losses, or the existence of significant DTAs that are set to expire unused. A cumulative loss over a three-year period is often considered strong negative evidence that is difficult to overcome, while positive evidence can include a strong history of earnings or existing contracts.

Accounting for Uncertain Tax Positions

Accounting for uncertain tax positions (UTPs) addresses how companies recognize, measure, and disclose tax benefits that tax authorities might challenge. This guidance ensures financial statements reflect the potential for a tax position to be disallowed upon audit.

A tax position is defined broadly and can include a decision not to file a tax return in a particular jurisdiction, the allocation of income among different states or countries, or the characterization of an expense as deductible. An uncertain tax position arises when there is uncertainty about whether the stance taken will be sustained on its technical merits if examined by a taxing authority.

ASC 740 prescribes a two-step process for UTPs, starting with recognition. A company determines if it is “more likely than not” (a greater than 50% probability) that its tax position will be sustained upon examination based on its technical merits. If this threshold is not met, no tax benefit can be recorded.

If the recognition threshold is met, the second step is measurement. The benefit is measured as the largest amount of tax benefit that is cumulatively greater than 50% likely to be realized upon settlement. For example, if a $75 benefit has a 70% cumulative probability of being realized, while a $100 benefit has only a 30% probability, the company would record a tax benefit of $75 and a liability for the unrecognized $25.

Required Financial Statement Disclosures

ASC 740 requires an extensive set of disclosures in the footnotes to the financial statements. These disclosures provide users with information to understand a company’s income tax position and the factors affecting its tax expense.

Companies must disclose the components of their deferred tax assets and liabilities. This includes a breakdown of the tax effects of each major type of temporary difference and carryforward, such as those from warranty reserves or net operating loss carryforwards.

A disclosure is required for the valuation allowance. Companies must disclose the total valuation allowance at the beginning and end of the period, along with any net change. A significant increase in the allowance can indicate to investors potential concerns about a company’s future profitability prospects.

The rate reconciliation is another required disclosure. This table reconciles the reported income tax expense with the amount that would result from applying the statutory federal income tax rate to the company’s pre-tax book income. Starting in 2025, many public companies must provide more detail, breaking down the reconciliation into categories like state and local taxes, foreign tax effects, and tax credits.

Companies must provide a tabular reconciliation of the total amount of unrecognized tax benefits at the beginning and end of the period. This “UTP roll-forward” shows the additions for tax positions taken in the current year, additions for positions taken in prior years, reductions for settlements with tax authorities, and reductions due to the lapse of the statute of limitations. Companies must also disclose the total amount of unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate.
