S Corporations
This topic covers S corporation eligibility, election, termination, shareholder basis, distributions, separately stated items, built-in gains, reasonable compensation, and tax return preparation.
How to study for CPA REG
Build every answer around taxpayer type, tax year, filing obligation, basis, character, limitation, and procedural consequence.
Core concepts
Concept 1
S Corporations questions test whether a CPA candidate can apply tax law, federal procedure, business law, or entity tax rules to a practical client fact pattern.
Exam cue: Identify the taxpayer type, tax year, transaction, return, authority, and dollar amount or deadline being tested.
Concept 2
The best REG answer usually identifies the taxpayer, transaction, year, tax basis, filing obligation, limitation, and procedural consequence before calculating.
Exam cue: Decide whether the task is inclusion, deduction, credit, basis, gain or loss, filing, penalty, representation, or legal liability.
Concept 3
Eliminate answers that skip statutory requirements, mix individual and entity rules, ignore basis, overlook filing deadlines, or choose a tax result without checking limitations.
Exam cue: Check limitations, character, timing, basis ordering, related-party rules, and whether the amount belongs on an individual or entity return.
Risk pitfalls and guardrails

Memory anchors
S Election
An S election allows a qualifying corporation to pass through income and loss to shareholders.
Eligible Shareholder
Eligible S corporation shareholders are limited by statute and generally exclude partnerships and corporations.
One Class of Stock
An S corporation generally may have only one class of stock for economic rights.
Shareholder Basis
S corporation shareholder basis increases for income and contributions and decreases for distributions and losses.
Debt Basis
Debt basis can permit loss deduction when the shareholder directly loans money to the S corporation.
Distribution Ordering
S corporation distribution tax effects depend on basis, accumulated adjustments account, and earnings and profits.
Separately Stated
Separately stated items pass through because they may affect shareholders differently.
Built-In Gains Tax
Built-in gains tax can apply after C corporation assets become subject to S corporation status.
Reasonable Compensation
S corporation shareholder-employees should receive reasonable compensation for services.
Termination
S status can terminate when eligibility rules are violated or revoked.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
