Introduction
In the third quarter of 2024, Intel concluded that it was more likely than not that it would be unable to use most of its US deferred tax assets. The reason was arithmetic as much as judgment: impairments and restructuring charges that quarter pushed it into a cumulative pre-tax loss over the previous three years. The resulting valuation allowance, together with related items, added $9.9 billion to its income tax provision for the year. Intel reported a pre-tax loss of $11.2 billion for 2024 and, instead of a tax benefit, a tax expense of $8.0 billion, an effective rate of 71.6% on a loss.
No cash changed hands. The charge recorded management's view that tax deductions Intel had already earned might never be worth anything, because it might not earn enough taxable income to use them. That view is the heart of accounting for deferred tax assets, and the valuation allowance is the mechanism that records it.
How Deferred Tax Assets Arise
A deferred tax asset represents tax that a company expects to save in the future because of something that has already happened. Most come from two sources:
- Deductible temporary differences: expenses recognized in the books before they are deductible for tax, such as warranty and litigation reserves, accrued compensation, lease liabilities, and research costs that had to be capitalized for tax.
- Carryforwards: tax losses and tax credits that could not be used in the year they arose; losses can be applied against future taxable income, and credits against future tax.
- Deferred tax asset
The future reduction in income taxes that a company expects from deductible temporary differences and from tax loss and credit carryforwards, measured at the enacted tax rates expected to apply when they are used. It is recognized under Accounting Standards Codification (ASC) 740, reduced by a valuation allowance if realization is not more likely than not.
Loss carryforwards are covered in detail in net operating losses. The two kinds of book-tax difference, and why only temporary ones create deferred taxes, are explained in permanent vs temporary differences. What sets deferred tax assets apart from deferred tax liabilities is that their value is conditional. A deferred tax liability will be paid if the company stays in business and the difference reverses. A deferred tax asset saves tax only if the company has taxable income to deduct it from.
The Valuation Allowance Test
US GAAP records deferred tax assets in full and then asks whether it is more likely than not, a likelihood of more than 50%, that some or all of them will not be realized. If so, the company records a valuation allowance against the portion it does not expect to use. The allowance is charged to income tax expense, and reversing it later produces a tax benefit.
- Valuation allowance
A reduction of deferred tax assets, under ASC 740, for the portion that is more likely than not to go unused because the company will lack sufficient taxable income of the right character, in the right jurisdictions, before the assets expire. Changes in the allowance usually run through income tax expense.
ASC 740 identifies four sources of taxable income that can support realization, as RSM's guide to assessing the need for a valuation allowance summarizes:
- Future reversals of existing taxable temporary differences, such as deferred tax liabilities on depreciation.
- Future taxable income, excluding those reversals.
- Taxable income in prior years, where the law allows losses to be carried back.
- Tax planning strategies the company would carry out if needed, such as accelerating taxable income to use a carryforward before it expires.
The first source is the most objective: a company with deferred tax liabilities scheduled to reverse in the same periods and jurisdictions can usually support an equal amount of deferred tax assets without relying on forecasts. Beyond that, the judgment turns on projected income, which is where the evidence is weighed.
The Weight of Cumulative Losses
The test weighs positive evidence, such as a strong earnings history, existing contracts and appreciated assets, against negative evidence, such as recent losses, carryforwards that have expired unused and a weak outlook. One piece of negative evidence carries particular weight: a cumulative loss in recent years, conventionally measured as pre-tax income over the current and two preceding years. Once a company is in that position, its own forecasts of a return to profit generally carry little weight, because they are hard to verify objectively. That is why Intel's charge followed so directly from the quarter in which its three-year total turned negative.
Intel's Allowance
Intel's 2024 annual report shows the effect on its deferred tax balances:
| Line item | 2023 | 2024 |
|---|---|---|
| R&D expenditures capitalization | 7,726 | 10,709 |
| State credits and net operating losses | 2,624 | 2,830 |
| Inventory, compensation, litigation and other | 4,181 | 4,425 |
| Gross deferred tax assets | 14,531 | 17,964 |
| Valuation allowance | (3,047) | (13,974) |
| Deferred tax assets, net of allowance | 11,484 | 3,990 |
| Deferred tax liabilities | (6,211) | (4,849) |
| Net deferred tax assets (liabilities) | 5,273 | (859) |
Source: Intel 2024 Form 10-K. Inventory, compensation, litigation and other combines five lines disclosed separately. The valuation allowance increased by 10,927 during 2024, largely for US deferred tax assets.
Gross deferred tax assets actually grew in 2024, to $18.0 billion, mostly because of research costs capitalized for tax. The allowance grew faster, from $3.0 billion to $14.0 billion, leaving deferred tax assets of $4.0 billion after the allowance, less than Intel's $4.8 billion of deferred tax liabilities, so its net position flipped from an asset to a liability. In the rate reconciliation, the federal valuation allowance alone added 93.2 percentage points to the effective rate.
Releases, Increases and Law Changes
A valuation allowance moves in both directions, and each move hits the effective tax rate. Increases follow losses, impairments, restructuring or a weaker outlook. Releases follow a sustained return to profitability, and can make a year's net income look far stronger than its operations. Both are usually excluded from adjusted earnings and from the normalized tax rate used in forecasts.
Allowances can also follow a change in law. In the third quarter of 2025, Meta recorded a one-time, non-cash tax charge of $15.93 billion that included a valuation allowance against its US federal deferred tax assets, as its results release explains. The 2025 tax law's faster deductions for research and equipment lowered Meta's expected regular federal tax, but the 15% corporate alternative minimum tax limits how far those savings go, so deferred tax assets that would have reduced regular tax were no longer expected to be fully usable. Meta's effective rate for the quarter was 87%; excluding the charge, it would have been 14%. Part of the allowance came back within months: Treasury's Notice 2026-7 changed how the minimum tax treats catch-up research deductions, and Meta recorded an $8.03 billion benefit in the first quarter of 2026, a reminder that allowances move with new guidance as well as with earnings.
What Bankers Do With Deferred Tax Assets
In valuation, deferred tax assets that will be used soon are worth something, and net operating losses in particular are often valued separately, as the present value of the taxes they will save. An allowance does not mean the attributes are worthless to a buyer: an acquirer with taxable income may be able to use them, subject to the Section 382 limits on losses after an ownership change. In accretion and dilution work and in forecasting earnings per share (EPS), bankers strip allowance changes out of the tax rate. In credit work, the allowance itself has no cash effect, but the reasons behind it, recent losses and a weak outlook, are exactly what a lender is assessing. The deferred tax liabilities that offset these assets are covered in deferred tax liabilities.
Deferred tax assets sit on the balance sheet as a record of tax already earned but not yet saved. The valuation allowance is the accounting's judgment of how much of that saving will actually arrive. For a banker, both the size of the allowance and the reason it moved say something about the company's prospects that the operating results alone may not.
