Tax Computation and Other Taxes
This topic covers taxable income, regular tax, AMT, household employees, self-employment tax, clergy and military provisions, income in respect of decedent, NIIT, additional Medicare tax, and other taxes.
How to study for EA Part 1
Build every answer around taxpayer data, filing status, income category, deduction or credit eligibility, forms, limitations, and reporting consequences.
Core concepts
Concept 1
Tax Computation and Other Taxes questions test whether an enrolled agent candidate can apply individual income tax rules to Form 1040 fact patterns for the tested tax year.
Exam cue: Identify taxpayer, filing status, dependency, tax year, source document, form, and whether the issue is income, deduction, credit, tax, advice, or specialized return.
Concept 2
The best answer usually identifies filing status, taxpayer data, income category, deduction or credit rule, limitation, reporting form, and penalty consequence before calculating.
Exam cue: Check thresholds, phaseouts, basis, holding period, substantiation, due dates, and whether the item is refundable, nonrefundable, taxable, excluded, or deferred.
Concept 3
Eliminate answers that ignore documentation, mix refundable and nonrefundable credits, skip basis, overlook special filing statuses, or use a prior-year rule when current-year facts control.
Exam cue: Tie the result to Form 1040 reporting, schedules, information returns, estimated tax, penalty relief, or future-year planning.
