S Corporation Compliance and Basis

Exam Insight

S corporations are pass-through entities, so the TCP exam tests eligibility, the per-share per-day allocation of income, and the strict stock-then-debt basis ordering that limits loss deductions. Distributions interacting with AAA and C-corporation E&P, plus the built-in gains tax, are perennial high-value testing points.
