Corporate taxable income, book-tax differences, the dividends-received deduction, and distributions.

Hard 1 hr 10 minArea V: Federal Taxation of Entities

Formation: Section 351

No gain or loss is recognized on a transfer of property to a corporation solely in exchange for stock if the transferors are in control (80%) immediately after. Boot received triggers gain up to the lesser of realized gain or boot. Services contributed are not property — the recipient recognizes compensation income.

Dividends-received deduction (DRD)

Ownership in the payerDRD percentage
Less than 20%50%
20% to less than 80%65%
80% or more (affiliated)100%

A taxable income limitation applies (the DRD generally cannot exceed the same percentage of taxable income before the DRD), unless taking the full DRD creates or increases a net operating loss.

Distributions to shareholders

Ordering: taxable dividend to the extent of current and accumulated earnings and profits (E&P) → then a tax-free return of capital reducing stock basis → then capital gain.

IMPORTANT: A corporation distributing appreciated property recognizes gain as if it sold the property at FMV. It does not recognize loss on distributing depreciated property.

EXAM TIP: Corporate charitable contributions are limited to 10% of taxable income (computed before the charitable deduction, DRD, and NOL carrybacks), with a 5-year carryforward. Corporate capital losses offset only capital gains — back 3, forward 5.
