C corporation compliance topics covering taxable income, loss usage, shareholder transactions, and earnings and profits.
This chapter covers the main C corporation compliance rules tested in TCP. The work centers on taxable-income computation, the use of losses and special deductions, the tax effect of shareholder transactions, and the role of earnings and profits in classifying distributions.
C corporation questions should separate entity-level tax from shareholder-level treatment. The corporation computes taxable income and E&P, while shareholders may face dividend, return-of-capital, redemption, or gain consequences depending on the transaction.
| Compliance area | First question | Common TCP trap |
|---|---|---|
| Taxable income and special deductions | Which book-tax adjustments, DRD limits, or charitable limits affect taxable income? | Applying individual or pass-through rules to a C corporation. |
| NOLs, capital losses, and Section 382 | Which loss type exists and whether ownership change limits usage. | Letting corporate losses offset income without checking category and limitation rules. |
| Shareholder transactions | Is the transaction a contribution, redemption, distribution, or sale-like event? | Treating all shareholder cash flows as dividends. |
| E&P and distribution ordering | Does E&P support dividend treatment before return of capital or gain? | Computing taxable income correctly but misclassifying the shareholder distribution. |
| Step | What to do | Why it matters on TCP |
|---|---|---|
| 1. Compute corporate taxable income | Start with income, deductions, book-tax adjustments, DRD, charitable limits, and special corporate items. | The entity-level tax result is separate from shareholder treatment. |
| 2. Apply loss rules | Classify NOLs, capital losses, and ownership-change limitations before offsetting income. | Corporate losses do not all behave like ordinary individual losses. |
| 3. Analyze shareholder transactions | Separate contributions, loans, redemptions, sales, dividends, and property distributions. | The same cash movement can produce different entity and shareholder consequences. |
| 4. Compute E&P when distributions appear | Determine current and accumulated E&P before classifying dividends, return of capital, or gain. | Distribution character depends on E&P, not only on corporate taxable income. |
| 5. Tie the result to reporting | Identify return treatment, shareholder reporting, basis effects, and documentation needed to support the transaction. | TCP often asks for the compliance consequence after the tax character is known. |
| Checkpoint | Exam use | What to avoid |
|---|---|---|
| Entity-level computation | Start with corporate taxable income, book-tax adjustments, special deductions, and credits before shareholder effects. | Blending corporate and shareholder tax results into one computation. |
| Loss category | Separate NOLs, capital losses, passive limits where relevant, and ownership-change constraints. | Letting every corporate loss offset every income category immediately. |
| Shareholder transaction type | Classify the movement as contribution, loan, dividend, redemption, property distribution, sale, or compensation. | Treating every owner cash flow as a dividend. |
| E&P support | Compute current and accumulated E&P before determining dividend, return of capital, or gain character. | Using taxable income as a substitute for E&P. |
| Reporting consequence | Identify the corporate return item, shareholder reporting, basis change, and documentation trail. | Stopping after the tax character without explaining how it is reported. |
