21.4 Taxation Practice Basics

Key Takeaways

  • Taxation is one of the twenty-five areas of law NALS lists under Part 4 Legal Knowledge, and paralegal work in the field is dominated by procedure and deadlines rather than by computation.
  • The authority hierarchy runs from the Internal Revenue Code through Treasury regulations to revenue rulings and procedures, with private letter rulings binding only the taxpayer who requested them.
  • A statutory notice of deficiency, called the 90-day letter, is the ticket to Tax Court: a petition filed within 90 days permits litigation without paying the tax first.
  • The general assessment limitations period is three years from filing, extended to six years for a substantial omission of gross income and unlimited for a false return or a failure to file.
  • Circular 230 governs practice before the IRS, and only enrolled agents, attorneys, and CPAs hold unlimited representation rights, so a paralegal never represents a taxpayer before the IRS.

21.4 Taxation Practice Basics

[!NOTE] NALS PP Exam Blueprint Focus: Taxation appears in the Part 4 Legal Knowledge list of areas of law. A PP candidate is not expected to compute a tax liability. What is expected is fluency in the procedural framework — the authorities, the deadlines, the forums, and the boundary between paralegal support and prohibited representation.

The Hierarchy of Tax Authority

LevelSourceWeight
StatuteThe Internal Revenue Code, Title 26 of the United States CodeControlling, subject to constitutional limits
TreatiesBilateral income tax treatiesCoordinate with the Code
RegulationsTreasury regulations — final, temporary, and proposedFinal and temporary regulations carry substantial authority; proposed regulations do not bind
Revenue rulingsThe IRS's published position applied to a stated set of factsBinding on the IRS; taxpayers may rely if facts are substantially identical
Revenue proceduresPublished statements of internal practice and procedureGuidance on how to do something
Private letter rulingsRulings issued to a specific taxpayer on requestBinding only as to that taxpayer; may not be cited as precedent
Notices and announcementsInterim guidancePersuasive
Case lawTax Court, district courts, Court of Federal Claims, courts of appeals, Supreme CourtPrecedential within the hierarchy

A paralegal researching a tax question checks currency with particular care, because the Code is amended frequently and because a regulation can be outdated relative to a statutory amendment.

Entity Taxation at a Glance

EntityTax treatment
Sole proprietorshipReported on the owner's individual return; no separate entity-level tax
General and limited partnershipPass-through; the entity files an information return and issues Schedule K-1 to partners
Limited liability companyDefault pass-through — disregarded if single-member, partnership if multi-member — with an election available to be taxed as a corporation
C corporationEntity-level tax on income, with a second tax at the shareholder level on distributions
S corporationPass-through, subject to eligibility limits on the number and type of shareholders and a single class of stock
Trust and estateTaxed on retained income; distributed income generally carries out to beneficiaries
Exempt organizationExempt from income tax on exempt-function income; may owe tax on unrelated business income

Entity classification drives the choice-of-entity analysis that appears in transactional practice, and the paralegal's role is usually assembling formation documents and filing the elections rather than advising on the choice.

Examination and Appeals

StageWhat happens
Return filingThe return starts the assessment limitations period
ExaminationCorrespondence, office, or field audit; information document requests; possible summons
Revenue agent report and 30-day letterProposed adjustments plus an invitation to protest to the Independent Office of Appeals within 30 days
Appeals conferenceSettlement based on hazards of litigation; the Appeals function is independent of examination
Statutory notice of deficiency (90-day letter)The formal determination of a deficiency
Tax Court petitionMust be filed within 90 days of the notice — 150 days if addressed outside the United States
Assessment and collectionFollows if no petition is filed

[!WARNING] The statutory notice of deficiency is the single most important document in tax procedure. It is the taxpayer's ticket to the United States Tax Court, and it is the only route to litigating the liability without paying the tax first. The 90-day period is jurisdictional and cannot be extended. A paralegal who receives a 90-day letter calendars the deadline immediately, records the date on the notice, and escalates the same day.

Choosing the Litigation Forum

ForumPrepayment required?Jury?Notes
United States Tax CourtNoNoSpecialized tax judges; small case procedure available for disputes under a statutory threshold, with no appeal
United States District CourtYes — pay, then sue for refundYesGeneral jurisdiction court
United States Court of Federal ClaimsYes — pay, then sue for refundNoNationwide jurisdiction

A refund suit requires first filing an administrative claim for refund and having it denied or six months elapse.

Limitations Periods

SituationPeriod
General assessment3 years from the later of the filing date or the due date
Substantial omission of more than 25% of gross income6 years
False or fraudulent return, or no return filedUnlimited
Collection after assessment10 years, subject to suspensions
Refund claimThe later of 3 years from filing or 2 years from payment

A taxpayer may consent to extend the assessment period, and various events — bankruptcy, a pending offer in compromise, a collection due process request — suspend the running of the collection period.

Collection

The collection sequence:

  1. Assessment, followed by notice and demand for payment.
  2. A federal tax lien arises automatically on assessment and attaches to all of the taxpayer's property; filing a Notice of Federal Tax Lien perfects priority against competing creditors.
  3. Levy seizes property, following a final notice of intent to levy and notice of the right to a hearing.
  4. Collection Due Process hearing — a request filed within the statutory window after the lien filing or levy notice suspends collection and preserves Tax Court review of the Appeals determination.

Resolution alternatives:

OptionDescription
Installment agreementPayment over time; streamlined options exist below dollar thresholds
Offer in compromiseSettlement for less than the full amount based on doubt as to collectibility, doubt as to liability, or effective tax administration
Currently not collectible statusCollection suspended for financial hardship
Penalty abatementReasonable cause, statutory exception, or first-time abatement
Innocent spouse reliefRelief from joint liability under one of three statutory paths

Estate, Gift & Employment Taxes

  • Estate tax is reported on the federal estate tax return, generally due nine months after death with an available extension to file. The portability election preserves a deceased spouse's unused exclusion for the survivor and must be made on a timely filed return.
  • Gift tax is reported on the annual gift tax return for gifts exceeding the annual exclusion or gifts of future interests. Because exclusion and exemption amounts are indexed and change by statute, a paralegal always verifies the current figures rather than relying on a prior year's worksheet.
  • Employment taxes carry a distinct exposure: the trust fund recovery penalty imposes personal liability on responsible persons who willfully fail to collect and pay over withheld taxes. It reaches officers, bookkeepers, and anyone with authority over which creditors get paid.

Practice Standards and the Paralegal's Limits

Circular 230 governs practice before the IRS. Representation rights are tiered:

PractitionerRights
Attorney, CPA, enrolled agentUnlimited representation before the IRS
Annual filing season program participantLimited representation for returns they prepared
Unenrolled return preparerVery limited
ParalegalNone — a paralegal never represents a taxpayer before the IRS

[!WARNING] Tax is a high-risk unauthorized practice area for paralegals. A paralegal may gather records, prepare schedules and summaries, draft documents for attorney review, calendar deadlines, and communicate the attorney's instructions. A paralegal may not sign a power of attorney as representative, appear at an examination or Appeals conference as the taxpayer's representative, advise a client on a filing position, or give an opinion on liability.

A limited federally authorized tax practitioner privilege protects some tax advice communications with a federally authorized practitioner, but it is narrower than the attorney-client privilege and does not apply in criminal matters or to tax shelter promotion.

The Paralegal Workstream

  1. Deadline control — 30-day and 90-day letters, refund claim deadlines, collection due process request windows, estate and gift return due dates.
  2. Document assembly — organizing returns, notices, transcripts, and correspondence into a chronological administrative file.
  3. Transcript analysis — ordering and reading account and return transcripts to reconstruct assessment and payment history.
  4. Financial statement preparation — assembling the income, expense, asset, and liability data supporting an installment agreement or offer in compromise, for attorney review.
  5. Power of attorney processing — preparing the representation form for the attorney's signature and filing it.
  6. Estate tax return support — asset schedules, appraisals, date-of-death valuations, and deduction documentation.
