Overview
This lecture covers the fundamentals of deferred taxes and income tax accounting, focusing on the differences between financial reporting rules and tax regulations, particularly temporary and permanent differences and their impact on deferred tax assets and liabilities.
Financial Reporting vs. Tax Accounting
- Financial reporting rules (books) and tax return rules (tax) are set by different authorities (FASB vs. IRS).
- Tax rules often aim to influence behavior (e.g., accelerated depreciation) and prevent fraud (e.g., cash basis for certain expenses).
- "Books" refers to financial statements, while "tax" refers to income tax returns.
Temporary and Permanent Differences
- Temporary differences are timing issues; revenue/expense recognized in different periods for books vs. tax but total amount is the same.
- Permanent differences never reverse and do not create deferred tax assets/liabilities.
Key Examples of Temporary Differences
- Installment sale: Full revenue recognized upfront in books, recognized as cash is received for tax.
- Warranty expense: Estimated expense recognized upfront in books, only deducted when paid for tax.
- These differences result in deferred tax liabilities (DTL) or deferred tax assets (DTA).
Deferred Tax Liabilities and Assets
- DTL: Arise when tax payments are postponed to future periods (e.g., accelerated tax depreciation).
- DTA: Arise when future tax deductions are expected (e.g., warranty liabilities).
- Calculate DTL/DTA as the temporary difference times the tax rate, using the balance sheet method.
- Only temporary differences result in DTAs or DTLs.
Journal Entry Steps for Income Taxes
- Calculate income tax payable based on taxable income and tax rate.
- Calculate ending balances for DTAs and DTLs (balance sheet approach).
- Income tax expense is the plug to balance the entry after adjusting DTAs/DTLs.
Valuation Allowance for DTAs
- If some DTAs are unlikely to be realized (e.g., due to ongoing losses), a valuation allowance (contra asset) is set up.
- Changes in the valuation allowance affect income tax expense dollar-for-dollar.
- Valuation is jurisdiction-specific and heavily scrutinized by auditors.
Permanent Differences
- Items such as tax-exempt interest or non-deductible expenses are permanent differences.
- Permanent differences do not create DTAs or DTLs and are simply excluded from deferred tax calculations.
Tax Rate and Presentation
- DTAs and DTLs are recalculated if tax rates change, but only when the new rate is enacted.
- All DTAs and DTLs are presented as non-current items on the balance sheet.
- Netting DTAs and DTLs is only allowed within the same tax jurisdiction.
- Disclosures must include details on DTAs, DTLs, valuation allowances, and rate reconciliations.
Key Terms & Definitions
- Deferred Tax Liability (DTL) — Future tax owed due to temporary differences where taxable income is less than book income.
- Deferred Tax Asset (DTA) — Future tax benefit due to temporary differences where taxable income exceeds book income.
- Temporary Difference — Timing difference in recognizing income/expense for book vs. tax purposes, which reverses over time.
- Permanent Difference — Difference between book and tax income/expense that never reverses.
- Valuation Allowance — Contra asset account reducing DTAs when realization is not likely.
