S Corporation and Partnership Planning

REG planning coverage for S corporation and partnership timing, basis, asset-disposition, and financing strategies.

This chapter applies entity-tax rules to practical planning choices for S corporations and partnerships. The central skill is recognizing which elections, timing decisions, and financing structures improve tax results without losing sight of basis and character consequences.

Pass-through planning questions should be solved from both the entity and owner perspectives. A planning move can improve current-year income, but still create a basis limitation, character problem, built-in gain issue, or debt-allocation consequence.

Pass-Through Planning Lens

Planning area First question Exam risk
Built-in gains Does prior C corporation history or appreciated property affect the current transaction? Treating an S corporation as if entity history never matters after election.
Income timing and elections Can timing be accelerated, deferred, or elected without violating method or eligibility rules? Choosing a tax-saving move without checking whether the election is available.
Income shifting and basis recovery Does the owner have enough basis and proper character support for the benefit? Focusing on entity income while missing owner-level limitations.
Partner and shareholder loans Does the financing structure create basis, at-risk support, or repayment consequences? Assuming all debt affects S corporation shareholders and partners the same way.

Pass-Through Planning Sequence

Step What to do Why it matters on REG
1. Identify the entity regime Determine whether the planning issue belongs to S corporation rules, partnership rules, or both. The two pass-through forms handle ownership, debt, allocations, and distributions differently.
2. Protect eligibility and elections Check S status, partnership allocations, accounting methods, timing elections, and filing requirements. A tax-saving plan is weak if the election or entity treatment is invalid.
3. Model owner-level basis Track shareholder stock and debt basis, partner outside basis, liabilities, and suspended losses. Pass-through planning usually fails at the owner level before it fails at the entity level.
4. Evaluate character and timing Consider ordinary income, capital gain, built-in gain, passive activity, and distribution character. Planning choices can change both when income is taxed and what type of income it is.
5. Document support for the strategy Tie the planning move to agreements, loan terms, business purpose, elections, and reporting positions. REG planning answers should be legally supportable, not merely tax efficient.

How to Use This Chapter

  • Read this chapter after the core S corporation and partnership chapters, not before them.
  • Focus on what planning move changes the tax result and what compliance or basis cost comes with it.
  • Revisit it when an exam scenario asks for the best next step rather than the mechanical rule alone.
