Only cash expenses (D) describes cash method, not the general rule.
Which of the following correctly describes the limitation on the dividends received deduction?
Explanation: The DRD is limited to the applicable percentage of taxable income (without the DRD), but this limitation does not apply if claiming the full DRD results in a net operating loss. Answer C is correct. The net income limitation (A) is not precisely stated. A flat 50% (B) ignores ownership tiers. The taxable income limit applies at all ownership levels below 80% (D).
A corporation has a net operating loss (NOL) for the current year. Under current law (post-TCJA), the corporation may:
Explanation: Post-TCJA, NOLs arising after 2017 can only be carried forward (no carryback for most taxpayers), indefinitely, but are limited to 80% of taxable income in the carryforward year. Answer B is correct. The 2-year carryback/20-year carryforward (A) was the pre-TCJA rule. The 5-year carryback (C) applies to farming NOLs. The 100% offset (D) was the pre-TCJA rule.

Explanation: Corporate dividends are not deductible - they represent a distribution of after-tax profits, creating the classical double taxation of corporate income. Answer C is correct. Dividends are not business expenses (A). No loss carryforward is created (B). No E&P-based deduction exists for paid dividends (D).
Which of the following is a deduction available to C corporations but NOT to individual taxpayers?
Explanation: The DRD is a deduction unique to corporations, allowing partial exclusion of dividends received from other domestic corporations to reduce double taxation. Answer B is correct.

A corporation's Form 1120 requires Schedule M-1 or M-3 to reconcile:
Explanation: Schedule M-1/M-3 reconciles book income to taxable income, identifying all book-tax differences (depreciation, meals, penalties, etc.). Answer A is correct. Year-over-year reconciliation (B) is not M-1/M-3's purpose. E&P reconciliation (C) is on Schedule M-2. State apportionment (D) is on separate state returns.
A corporation's earnings and profits (E&P) differ from taxable income because:
Explanation: E&P is a measure of economic capacity to pay dividends - it uses ADS straight-line depreciation (not MACRS), includes tax-exempt income, and makes other adjustments. Answer C is correct. E&P uses ADS depreciation (not accelerated) (A). E&P is not simply taxable income plus DRD (B). E&P is not GAAP-based (D).
Which of the following is subject to the personal holding company (PHC) tax?
Explanation: The PHC tax applies to closely held corporations with concentrated ownership (5 or fewer = 50%+) and primarily passive/PHC income (60%+ threshold). Answer D is correct. Retained earnings (A) triggers the AET, not PHC tax. Any corporation earning passive income (B) is too broad. Public corporations (C) don't meet the closely held requirement.

Explanation: The Inflation Reduction Act's CAMT applies to large corporations (average annual adjusted FSI of 1billion+)at151 billion FSI, not $1 million taxable income (A). Pass-through entities are not subject to CAMT (B). Not all book/tax differences trigger CAMT (C).
A corporation receives tax-exempt municipal bond interest of $50,000. This income:
Explanation: Tax-exempt interest is excluded from taxable income but must be included in E&P because E&P measures economic capacity to pay dividends. Answer B is correct.
