How to study for EA Part 2

Build every answer around entity classification, filing obligation, owner basis, income and deduction character, payroll duties, accounting records, and specialized taxpayer rules.

Core concepts

Concept 1

Entity Classification, EIN and Tax Year questions test whether an enrolled agent candidate can apply business tax rules to entity, return, owner, and recordkeeping facts.

Exam cue: Identify the entity, tax year, owner role, form, accounting method, record source, and whether the issue is income, deduction, credit, basis, payroll, or advice.

Concept 2

The best answer usually identifies the business form, tax year, filing obligation, income or deduction character, owner-level consequence, and penalty exposure before calculating.

Exam cue: Check basis, distributions, depreciation, employment tax deposits, QBI limits, method changes, due dates, penalties, and information reporting.

Concept 3

Eliminate answers that ignore entity classification, basis, payroll deposits, accounting method, book-tax reconciliation, or specialized taxpayer filing requirements.

Exam cue: Tie the result to the correct business return, schedule, K-1, payroll form, book-tax reconciliation, owner basis, or specialized taxpayer return.

Risk pitfalls and guardrails

Solving as if every business were a sole proprietorship instead of respecting entity classification and owner-level rules.

Guardrail: Use a 15-second safety pause before finalizing your action.

Calculating a deduction or credit without checking basis, at-risk limits, passive limits, depreciation elections, or payroll compliance.

Guardrail: Use a 15-second safety pause before finalizing your action.

Missing specialized taxpayers such as trusts, estates, exempt organizations, retirement plans, farmers, and rental real estate.

Guardrail: Use a 15-second safety pause before finalizing your action.

Memory anchors

Sole Proprietorship

A sole proprietorship reports business income on the owner's individual return and is not a separate income tax entity.

Partnership

A partnership generally files an information return and passes separately stated items to partners on Schedule K-1.

Corporation

A corporation is a separate tax entity unless a valid S election changes pass-through treatment.

S Corporation

An S corporation passes items to shareholders and must satisfy eligibility and election requirements.

LLC Classification

An LLC's federal tax classification depends on owners and elections rather than state-law label alone.

EIN

An employer identification number identifies a business for employment, information return, and entity filing purposes.

Tax Year

A business tax year may be calendar, fiscal, or required by entity rules and elections.

Information Reporting

Forms W-2 and 1099 report compensation, payments, and other business transactions to taxpayers and the IRS.

Hobby Loss

A hobby versus business determination affects whether losses and deductions are allowed as business expenses.

Entity Election

Entity elections must be timely and consistent with the taxpayer's facts and requested classification.

Checkpoint rule

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
