The lists of DTA and DTL examples in your review course are a trap. Candidates who meticulously memorize them still fail the simulations because the exam doesn't test what creates a temporary difference; it tests if you can predict its future cash tax consequence.
Deferred tax assets (DTAs) and liabilities (DTLs) are noncurrent balance sheet accounts under FASB ASC 740. They arise from temporary differences between the financial statement carrying amount of an asset or liability and its tax basis, representing a future tax decrease (DTA) or increase (DTL) when that difference reverses.
Key facts
- Governing Standard
- FASB ASC 740, Income Taxes.
- Exam Section
- Financial Accounting and Reporting (FAR).
- Question Types
- Multiple-Choice Questions (MCQs) and Task-Based Simulations (TBS).
- Core Concept
- Arises from temporary differences in the book vs. tax basis of assets and liabilities.
- Valuation Allowance
- A contra-asset required when it's "more likely than not" (>50% chance) a DTA won't be realized.
- Tax Rate
- Use the enacted tax rate for the future period the difference is expected to reverse.
The AICPA reports the cumulative FAR pass rate was 44.5% in the first half of 2024 (AICPA). A flawed approach to core topics like deferred taxes is a primary reason otherwise strong candidates fall short.
How Deferred Taxes Actually Work (and Why They Matter on the FAR Exam)
Deferred tax accounting exists to properly match income tax expense with the book income reported in the same period. The entire concept is necessary because the rules for financial reporting (U.S. GAAP) differ from the rules for tax reporting (the Internal Revenue Code).

This mismatch creates a difference between the carrying amount of an asset or liability on the balance sheet and its tax basis. These differences are either permanent or temporary.
- Permanent Differences: These items impact either book income or tax income, but never both. Think of interest from a municipal bond—it's book income but is non-taxable. Or consider fines and penalties, which are book expenses but are not tax-deductible. These differences will never reverse and never create a deferred tax asset or liability.
- Temporary Differences: These are the source of all deferred taxes. They represent differences between the book and tax basis of an asset or liability that will reverse over time. A classic example is using straight-line depreciation for books but an accelerated method (MACRS) for tax. The total depreciation is the same over the asset's life, but the timing creates a temporary basis difference each year.
On the FAR exam, you will see complex simulations that require you to calculate the entire income tax provision. They test your judgment, not your memory. To see how these topics fit into the larger test, review the official FAR exam structure.
The most common error is calculating the temporary difference correctly but creating a DTA when it should be a DTL, or vice versa.
This is a logic problem.
A Decision Framework for Any Deferred Tax Question
To solve any deferred tax problem on the exam, you need a clear decision process. This framework, based on ASC 740, is how you apply professional judgment under pressure.
Step 1: Isolate the Book-Tax Basis Difference
For each balance sheet account, ask: Is the amount reported under GAAP different from its basis for tax purposes? If not, there is no deferred tax impact.
Step 2: Classify the Difference as Permanent or Temporary
This is the critical sorting step. A misclassification here guarantees a wrong answer.
| Difference Type | Definition | Exam Examples | Deferred Tax Impact |
|---|---|---|---|
| Permanent | Affects book or tax, but never both. The difference will not reverse. | • Municipal bond interest • Life insurance proceeds on key officer • Fines and penalties • 50% of meals expense | None. Affects the effective tax rate only. |
| Temporary | Affects both book and tax, but in different periods. The basis difference will reverse. | • Depreciation methods • Accrued warranty expense • Unearned revenue • Installment sales | Creates a DTA or DTL. |
Step 3: Predict the Future Tax Consequence (The DTA/DTL Test)
This is where candidates stumble. Do not rely on memorized lists. Use this forward-looking logic:
Let's apply this:
- Depreciation: Your asset's tax basis is $60k, but its book basis is $100k (due to accelerated tax depreciation). When this asset is eventually sold or fully depreciated, you will have $40k more in future taxable gain (or less future depreciation deduction) than book gain. This is a future taxable amount. It will make your future tax bill go up. This creates a DTL.
- Warranty Expense: You accrue a $50k warranty liability for book purposes, but its tax basis is zero until you pay the claims. When you pay the claims in the future, you will get a $50k tax deduction. This is a future deductible amount. It will make your future tax bill go down. This creates a DTA.
Step 4: Calculate the Deferred Tax Amount
Multiply the total temporary difference by the applicable future enacted tax rate. If a new tax rate has been signed into law for future years, you must use it. A merely proposed rate change must be ignored—a common exam trick.
Step 5: Evaluate DTAs for a Valuation Allowance
For any DTA, ASC 740 requires you to assess if it is "more likely than not" (a >50% chance) that the asset will be realized. If a company projects future losses and may not have enough taxable income to use the future deduction, it must record a valuation allowance.
Journal Entry: Income Tax Expense (or Benefit) DR, Valuation Allowance on DTA CR
This contra-asset reduces the net DTA on the balance sheet, reflecting the judgment that the asset is impaired.

Worked Example: Innovate Corp.
Let's apply the framework to a scenario mirroring a FAR simulation. A methodical approach prevents errors under exam pressure.
- Depreciation for book purposes is $80,000; for tax purposes, it is $120,000.
- The company received $30,000 in interest from municipal bonds.
Calculate Innovate Corp.'s current income tax expense, deferred income tax provision, and total income tax expense for 2026.
Here’s how to solve it step-by-step.
Step 1: Calculate Taxable Income and Current Tax Expense
Start with book income and adjust for all book-to-tax differences.
- Pretax Book Income: $500,000
- Subtract Permanent Difference (non-taxable income): ($30,000)
- Subtract Excess Tax Depreciation (temporary): ($40,000)
- ($120,000 tax depr. - $80,000 book depr.)
- Taxable Income: $430,000
Now, calculate the tax currently payable to the IRS.
- Current Income Tax Expense = Taxable Income × Tax Rate
- Current Income Tax Expense = $430,000 × 25% = $107,500
Step 2: Analyze the Temporary Difference and Calculate the Deferred Tax Provision
The only temporary difference is the $40,000 from depreciation.
- Logic Check: We took a larger tax deduction now. This means in the future, we will have smaller tax deductions available relative to our book expense. Smaller future deductions mean higher future taxable income. Higher future tax payments create a Deferred Tax Liability.
- Calculation: Increase in DTL = Temporary Difference × Future Enacted Tax Rate
- Increase in DTL = $40,000 × 25% = $10,000
This $10,000 is the deferred income tax expense for the year.
Step 3: Calculate Total Income Tax Expense
This is the GAAP-compliant expense reported on the income statement.
- Total Income Tax Expense = Current Tax Expense + Deferred Tax Expense
- Total Income Tax Expense = $107,500 + $10,000 = $117,500
You can verify this by multiplying the book income (adjusted for permanent differences only) by the tax rate: ($500,000 - $30,000) × 25% = $117,500. It matches.

Practice Questions to Test Your Judgment
Let's test these concepts with a few exam-style MCQs. VoraPrep's question bank has over 9,500 questions, all with detailed explanations from practicing CPAs.
Sample Question 1A company has a $50,000 unrealized gain on available-for-sale (AFS) debt securities reported in Other Comprehensive Income (OCI). For tax purposes, gains are not recognized until the securities are sold. The enacted tax rate is 21%. Which of the following is the correct accounting treatment?
At the beginning of Year 1, Kestrel Corp. had a deferred tax liability of $84,000. In Year 3, a new law is enacted, reducing the corporate tax rate from 21% to 20%, effective immediately. The DTL relates to an item originally recorded through income from continuing operations. What is the effect of this change on Year 3 income from continuing operations?
DTL DR $4,000 / Income Tax Expense CR $4,000. A credit to tax expense is a benefit, which increases net income. Therefore, the correct answer is A.
Sample Question 3
Apex Corporation reported book depreciation of $100,000 and tax depreciation of $150,000 for the current year. The enacted tax rate is 25%. This is the only temporary difference created this year. Apex has a $20,000 DTA on its balance sheet from a prior year related to warranty expenses. What should Apex report on its year-end noncurrent balance sheet?
- Calculate the current year's deferred tax item: The excess tax depreciation is $150,000 - $100,000 = $50,000. This temporary difference creates a future taxable amount, resulting in a Deferred Tax Liability (DTL). The DTL created this year is $50,000 × 25% = $12,500.
- Determine the ending balance sheet position: The company has a pre-existing Deferred Tax Asset (DTA) of $20,000.
- Net the balances for presentation: Under ASC 740, all DTAs and DTLs for a single tax jurisdiction are netted together and classified as noncurrent on the balance sheet.
- Calculation: Net Position = DTA - DTL = $20,000 - $12,500 = $7,500.
- Conclusion: Since the result is positive, the company reports a net deferred tax asset of $7,500. The correct answer is A.
How to Prepare for Deferred Taxes on the Exam
- Master the book-to-tax reconciliation. Practice building a schedule that starts with pretax book income and ends with taxable income. This skill is the foundation for nearly any income tax simulation.
- Focus on the "why." For every temporary difference, ask: will this cause me to pay more tax later (DTL) or less tax later (DTA)? This logical check prevents costly sign errors.
- Connect to other FAR topics. Deferred taxes are integral to business combinations and accounting for investments. Understanding these connections, similar to the long-term estimations required for pension accounting under FAR, is critical.
- Drill MCQs on key rules. In your final review, focus on questions about permanent vs. temporary differences, the valuation allowance, and tax rate changes. These are quick points if you are sharp on the rules.
