REG Individual Taxation and Return Computation

Individual-tax rules for income, deductions, credits, loss limits, and owner-level pass-through reporting.

This part covers the federal taxation of individuals. The goal is to move from gross income through deductions and limitations to the reporting consequences that affect the return and the taxpayer’s ultimate liability.

Individual tax questions are sequential. A correct deduction or credit answer can still be wrong if the candidate has already misclassified income, ignored a limitation, used the wrong filing status, or failed to connect pass-through information to the taxpayer’s return.

In This Part

Individual Return Lens

Computation area What to decide first Common REG trap
Gross income Whether an item is included, excluded, deferred, or separately characterized. Starting with deductions before identifying the tax base.
Deductions and credits Whether the item reduces income or tax liability and whether limitations apply. Treating deductions and credits as interchangeable.
Loss limits Which limitation regime applies and in what order. Applying a loss before checking basis, at-risk, passive, or other limits.
Pass-through reporting Character, separately stated items, basis, and owner-level limits. Combining pass-through amounts without preserving character.

Individual Tax Review Sequence

Step Return question Why order matters
1. Establish filing context What filing status, dependency facts, taxpayer age, and return limitations apply? Several deductions, thresholds, and credits depend on taxpayer status before computation begins.
2. Build gross income Which items are included, excluded, deferred, or separately characterized? The tax base must be correct before deductions and credits can be evaluated.
3. Apply deductions and AGI limits Which adjustments, standard or itemized deductions, and percentage limits apply? Many limitations depend on AGI or taxable-income ordering.
4. Compute credits and tax effects Which credits, additional taxes, prepayments, or carryovers affect final liability? Credits reduce tax rather than income and may be refundable, nonrefundable, or limited.
5. Preserve character Do pass-through items, capital items, passive losses, or carryovers retain special treatment? Recharacterizing separately stated amounts is a common source of wrong REG answers.

Individual Tax Checkpoints

Checkpoint Ask before finalizing Return consequence
Filing context Which filing status, dependency facts, age, residency, and taxpayer limitations apply? Thresholds, deductions, and credits often depend on status before amounts are computed.
Income character Is the item ordinary, capital, passive, portfolio, tax-exempt, deferred, or excluded? Character controls rates, limits, forms, and carryover treatment.
Deduction category Is the item an adjustment, standard or itemized deduction, business deduction, or limited personal expense? Ordering and AGI limits can change the allowable amount.
Loss limitation order Do basis, at-risk, passive activity, capital loss, or other limits apply first? Applying limits in the wrong order can produce a plausible but wrong answer.
Credit and payment treatment Is the item refundable, nonrefundable, carryforward, prepayment, or additional tax? Credits and payments affect liability differently from deductions.

How to Use This Part

  • Read this part in order because the individual tax computation builds step by step.
  • Focus on what changes inclusion, deduction, or limitation treatment.
  • Revisit these chapters whenever a REG miss turns on individual-return mechanics or pass-through reporting.
