Key concepts of deferred tax assets and liabilities, and how they impact financial statements.

• A. They are permanent differences that never affect taxes
• B. They arise from temporary differences and affect future tax outcomes; adjust for valuation allowances if not probable
• C. They only affect current year tax expense
• D. Valuation allowances are never needed for DTAs

Answer: (B)

Deferred taxes come from timing differences between how income and expenses are recognized for financial reporting and for tax purposes, creating assets and liabilities that will affect taxes in future periods. A deferred tax asset arises when deductible temporary differences or loss carryforwards can reduce future tax payments, while a deferred tax liability arises when taxable temporary differences will increase future tax payments as those differences reverse. These items usually sit on the balance sheet as noncurrent, and the income statement reflects both current tax expense and a deferred tax component that recognizes the future impact as the differences reverse. A valuation allowance is needed for a deferred tax asset when it isn’t probable that enough future taxable income will be available to realize the benefit. That’s why this option best captures the concept: they come from temporary differences and affect future tax outcomes, with valuation allowances applied if realization isn’t probable. The other statements miss important aspects: permanent differences do not reverse and don’t create DTAs/DTLs; these taxes impact more than just the current year as they reverse over time; and valuation allowances are sometimes required for DTAs when realization isn’t probable.
