A company has a $200,000 Deferred Tax Asset (DTA) from a net operating loss. Management projects strong future profits, but the company has a three-year history of actual losses. According to ASC 740, is a valuation allowance required?
The correct answer hinges on a single piece of evidence that outweighs all others. A history of recent losses is considered significant negative evidence that is difficult to overcome with projections alone, making a valuation allowance highly likely. The exam tests this specific judgment: can you weigh conflicting evidence the way a practitioner would?
On the FAR exam, accounting for income taxes requires applying ASC 740 to find the difference between book income (GAAP) and taxable income (tax code). These differences, if temporary, create deferred tax assets (DTAs) for future deductions and deferred tax liabilities (DTLs) for future taxable amounts on the balance sheet.

Why Is Income Tax Accounting so Heavily Tested on the FAR Exam?
Accounting for Income Taxes under ASC 740 is one of the most challenging topics on the Financial Accounting and Reporting (FAR) exam because it forces you to think in two different frameworks simultaneously: GAAP for financial reporting and the tax code for compliance. The exam is not testing your ability to prepare a tax return. It is testing your ability to recognize the financial statement impact of taxes payable today and taxes that will be saved or paid in the future.
The entire topic revolves around the mismatch between book income and taxable income. These differences create future tax consequences that must be accounted for on the current period's financial statements.
This content appears in both Multiple-Choice Questions (MCQs) and Task-Based Simulations (TBS). MCQs will test discrete rules, like identifying a permanent difference. A TBS, however, can present a full book-to-tax reconciliation and require you to calculate the current tax expense, deferred tax expense, and the ending DTA/DTL balances. The biggest mistake is thinking like a tax preparer. The examiner wants to see if you can apply GAAP to correctly identify and measure the deferred tax items on the balance sheet.
What Are the Core Rules of ASC 740 You Must Master?
Your mastery of income tax accounting depends on a clear, repeatable decision process. Don't just memorize rules; learn the logic that governs them. VoraPrep's adaptive learning engine targets this very skill, using our 9,500+ questions to build your analytical judgment.
The Decision Tree for Deferred Taxes
When you encounter any income or expense item, follow this sequence under pressure:
- Is there a difference between the GAAP treatment and the tax treatment? If no, stop. There is no deferred tax impact.
- Is the difference permanent or temporary? Permanent differences affect the tax rate calculation but stop here. Temporary differences move to the next step.
- If temporary, will it cause future taxable amounts or future deductible amounts?
- Future Taxable Amount: Creates a Deferred Tax Liability (DTL). You received a tax benefit now that will reverse later, requiring a higher tax payment in the future (e.g., accelerated depreciation for tax).
- Future Deductible Amount: Creates a Deferred Tax Asset (DTA). You paid more tax now but will get a deduction in the future (e.g., warranty expenses accrued for book but not yet paid).
- If you have a DTA, is it "more likely than not" (>50% chance) it will be realized? If not, you must record a Valuation Allowance to reduce the DTA to its net realizable value.
Permanent vs. Temporary Differences
Misclassifying an item here will invalidate your entire calculation. This is a frequent source of lost points.
| Type of Difference | Description | Creates Deferred Tax? | Examples |
|---|---|---|---|
| Temporary | A difference in timing that originates in one period and will reverse in a future period. | Yes | Depreciation methods, warranty liabilities, bad debt expense (allowance vs. direct write-off). |
| Permanent | An item that affects either book income or taxable income, but never both. It will not reverse. | No | Interest on municipal bonds, fines and penalties, life insurance premiums where the company is the beneficiary. |
The Valuation Allowance: Where Judgment is Tested
The valuation allowance is a favorite topic for examiners because it requires professional judgment, not just calculation. It is a contra-asset account that reduces the carrying value of a DTA. You must record one if it's more likely than not that the company won't generate enough future taxable income to use the deduction.
Per ASC 740, you must weigh all available evidence:
- Positive Evidence: A strong history of profitability, existing contracts that will produce future income, and actionable tax-planning strategies.
- Negative Evidence: A history of recent losses, expiring loss carryforwards, or major unsettled business circumstances.
A cumulative loss over the past three years is significant negative evidence that is very difficult to overcome with projections of future income alone.
> ✅ Tip: > A Net Operating Loss (NOL) carryforward is a classic source of a DTA. Under current tax law (post-TCJA), NOLs can be carried forward indefinitely but are generally limited to offsetting 80% of taxable income in a given year. This indefinite carryforward period is positive evidence for realizing the DTA, but it doesn't override the need for a valuation allowance if profitability is not more likely than not.
How Do You Solve a Full Income Tax Simulation?
Let's walk through a scenario that integrates these concepts. This is the exact structured approach you need for a complex FAR simulation.
> 💡 Worked example: > > In 2026, Innovate Corp. reports pre-tax book income of $5,000,000. The exam question specifies an enacted corporate tax rate of 25%. > > The following differences exist between book and taxable income: > 1. Innovate recognized $200,000 in warranty expense for GAAP purposes. It only paid and deducted $50,000 for tax purposes. > 2. The company took $400,000 in depreciation for tax purposes, but only $300,000 for book purposes. > 3. Innovate received $25,000 in interest from municipal bonds, included in book income. > > Calculate Innovate's (1) Current Tax Expense, (2) Deferred Tax Provision, and (3) Total Tax Expense for 2026.
Step 1: Calculate Taxable Income
Start with pre-tax book income and make precise adjustments to reconcile to taxable income.
- Pre-tax Book Income: $5,000,000
- Permanent Difference: Subtract non-taxable municipal bond interest: ($25,000)
- Temporary Difference (Warranty): The $200,000 book expense is not yet deductible for tax. The $50,000 paid is deductible. The net adjustment is an increase to book income of $150,000.
- Temporary Difference (Depreciation): Tax depreciation is $100,000 higher than book depreciation. This is an additional deduction, so we subtract it.
Calculation: $5,000,000 (Book) - $25,000 (Permanent) + $150,000 (Warranty) - $100,000 (Depreciation) = $5,025,000 Taxable Income

Step 2: Calculate Current Income Tax Expense
This is the amount payable to the IRS for the current year, based on taxable income.
- Taxable Income: $5,025,000
- Tax Rate: 25%
- Current Tax Expense (Payable): $5,025,000 * 0.25 = $1,256,250
Step 3: Calculate the Deferred Tax Provision
Analyze only the temporary differences to find their impact on the balance sheet and the deferred portion of tax expense.
- Warranty Difference: This creates a future deductible amount of $150,000. This results in a Deferred Tax Asset.
- DTA increase = $150,000 * 25% = $37,500
- Depreciation Difference: This creates a future taxable amount of $100,000. This results in a Deferred Tax Liability.
- DTL increase = $100,000 * 25% = $25,000
The net deferred tax effect is a $12,500 deferred tax benefit ($37,500 DTA - $25,000 DTL). This benefit reduces the total tax expense for the period.
> ⚠️ Exam trap: > The journal entry is key. A DTA is an asset (debit to increase), and a DTL is a liability (credit to increase). The plug is the deferred tax expense or benefit. > > Journal Entry: > Deferred Tax Asset (Dr.) ................... $37,500 > Deferred Tax Liability (Cr.) ................... $25,000 > Deferred Tax Benefit (Cr.) ................... $12,500 > > A credit to the expense/benefit account reduces total tax expense. The Vory tutor, available 24/7, can help you practice these entries until they are automatic.
Step 4: Calculate Total Income Tax Expense
This is the final GAAP income tax expense reported on the income statement.
- Formula: Total Tax Expense = Current Tax Expense - Deferred Tax Benefit
- Calculation: $1,256,250 - $12,500 = $1,243,750
You can perform a crucial self-check. Apply the tax rate to book income adjusted for permanent differences only: ($5,000,000 - $25,000) 25% = $4,975,000 0.25 = $1,243,750. It matches. Use this check on exam day to confirm your work.

Theory is one thing; application is everything. Try VoraPrep's free CPA practice questions to see how these concepts are tested.
Sample Question 1 During Q2 2026, Bradshaw Industries is preparing its interim financial statements. The company anticipates $500,000 in income for the full year and projects a total tax liability of $105,000. The company's income for Q2 was $150,000. What is the income tax expense Bradshaw should report for Q2? A) $31,500 B) $105,000 C) $21,000 D) Cannot be determined> Explanation: The correct answer is A. For interim reporting, you must use the estimated annual effective tax rate. First, calculate the rate: $105,000 (total tax) / $500,000 (total income) = 21%. Then, apply this rate to the current quarter's income: $150,000 * 21% = $31,500.
Sample Question 2 Apex Industries reports equipment on its balance sheet with a carrying amount that exceeds its tax basis. According to FASB ASC 740, this difference will result in future taxable amounts and should be recognized as a: A) Deferred tax liability B) Deferred tax asset C) Permanent difference D) Current tax payable> Explanation: The correct answer is A. When the book carrying amount of an asset is greater than its tax basis, it means more depreciation has been taken for tax purposes than for book purposes. This will reverse in the future, creating future taxable amounts. A future taxable amount results in a deferred tax liability.
