Traps that cost points
- S corporation basis ordering: income first, then distributions, then nondeductible expenses, then losses. Debt basis comes only from direct shareholder loans, not guarantees.
- Partnership liabilities change outside basis; relief of liabilities is a deemed cash distribution that can trigger gain.
- Section 179 is limited to business income; bonus depreciation is not.
- Unrecaptured section 1250 gain (25% max) is not ordinary recapture for individuals.

Frequently asked questions
How long should I study for Part 2?
Our editorial estimate is 50-80 hours, less if you prepare returns in this area daily. The IRS does not publish a recommended number.
Do I need 2026 numbers?
No. The 2026-27 exam tests 2025 law. Using 2026 amounts is a common way to pick a wrong answer.
