A valuation allowance is a special type of contra account found on a company's balance sheet. Think of it as a rainy-day fund in reverse. While a company might have a valuable asset called a deferred tax asset (DTA)—which is essentially a credit to be used against future taxes—the valuation allowance is management's official admission that they might not be able to use all of it. Under accounting rules, if it is “more likely than not” (a greater than 50% chance) that some portion of the DTA won't be realized, the company must create a valuation allowance to reduce the DTA's value on the books. This is a critical dose of reality. It tells investors that despite having this “asset,” the company isn't confident it will generate enough future taxable profit to actually benefit from it. The creation of this allowance directly increases a company's tax expense and lowers its net income, making it a key item for investors to watch.
For a value investor, the valuation allowance is more than just an accounting entry; it's a window into management's soul and the company's future prospects. A large or growing valuation allowance is a significant red flag. It’s a direct signal from the people who know the business best—management—that they are pessimistic about near-term profitability. If they don't believe they can make enough money to use their tax credits, why should you? Furthermore, this account has a direct and sometimes dramatic impact on reported earnings.
A savvy investor knows to dig into the footnotes of the financial statements to understand these movements. Is a sudden profit surge due to a genuine business improvement or just an accounting adjustment? The valuation allowance holds the clue.
Understanding the valuation allowance is easiest with a simple story.
Imagine a company, “Turnaround Inc.,” has a terrible year and reports a net operating loss (NOL) of $100 million. Tax laws often allow companies to use these losses to offset profits in future years. This ability to reduce future tax bills is a genuine economic benefit, so it's recorded as an asset—the Deferred Tax Asset (DTA). If the corporate tax rate is 21%, the DTA would be: $100 million (NOL) x 21% (Tax Rate) = $21 million (DTA) This $21 million asset now sits on Turnaround Inc.'s balance sheet.
Now, the accountants and management at Turnaround Inc. must look into their crystal ball. They review their business plans, industry trends, and past performance. After their analysis, they conclude that given the tough competition, it's “more likely than not” that they will only be able to generate enough future profit to use $15 million of that DTA. They cannot, in good faith, carry the DTA at its full $21 million value. They must record a valuation allowance to cover the difference: $21 million (Total DTA) - $15 million (Realizable DTA) = $6 million (Valuation Allowance) On the balance sheet, the entry looks like this:
That $6 million creation doesn't just sit on the balance sheet; it flows through the income statement as an increase to the tax expense, making a bad year's net income look even worse.
Let's fast forward two years. A new product from Turnaround Inc. is a smash hit, and the company is suddenly wildly profitable. Management is now highly confident they can use the entire original $21 million DTA. They can now “release” the $6 million valuation allowance. This has the opposite effect of its creation. The company's tax expense for the period is reduced by $6 million. This provides a massive, one-time boost to net income. An unsuspecting investor might see the headline profit number and think the company's core operations are more profitable than they actually are. This is a classic example of “low-quality earnings”—a profit boost that doesn't come from selling more goods or services and is not repeatable.
