The Definitive Guide to IRS Audit Representation

An IRS audit — the agency’s formal term is “examination” — is a review of your tax return to verify that income, deductions, credits, and other items were reported correctly under the law. The IRS’s authority comes from Internal Revenue Code Section 7602, which empowers the agency to examine books and records, summon documents and testimony, and take whatever evidence is relevant to determining a correct liability. An audit ends in one of three ways: no change (your return is accepted as filed), agreed (you sign off on adjustments), or unagreed (you dispute the adjustments and the case moves into the appeals and deficiency machinery this guide explains in Part Seven).

Three things an audit is not. It is not a criminal investigation — civil examinations and criminal tax cases run on entirely separate tracks, and the overwhelming majority of audits never come near the criminal side (though Part Seven-A covers the “eggshell audit” situations where that boundary demands professional care). It is not an accusation — many audits are triggered by statistical scoring or document mismatches, not suspicion. And it is not unlimited — the examiner is constrained by statutes of limitation, by scope rules in the Internal Revenue Manual, and by taxpayer rights that Congress wrote into the Code, most of which unrepresented taxpayers never invoke because they do not know they exist. That knowledge gap is precisely why professional IRS audit help changes outcomes.

1. Correspondence audits are conducted entirely by mail from IRS campuses and account for the large majority of all examinations. They target one or a few discrete items — the Earned Income Tax Credit, education credits, itemized deductions, a Schedule C line — and open with a letter (commonly Letter 566 or a CP75-series notice) asking for documentation. Their reputation as the “easy” audit is dangerously wrong: correspondence exams have the highest rate of taxpayers simply failing to respond adequately, and a blown correspondence audit produces the same legally binding assessment as any field exam. Campus units are also notorious for losing or misreading mailed documentation, which is why responses must be organized, indexed, and sent traceably.

2. Office audits take place at an IRS office before a Tax Compliance Officer. They cover broader issues than correspondence exams — typically several schedules of an individual return — and involve an interview. Under IRC §7521(c), a taxpayer who has a qualified representative under power of attorney generally cannot be required to attend alongside the representative absent an administrative summons; in practice, well-represented office audits proceed without the taxpayer in the room, which removes the single largest source of self-inflicted damage: unscripted answers.

3. Field audits are the full examination: a Revenue Agent — the IRS’s most trained examiner class — reviewing a business or high-income individual return at the taxpayer’s place of business, the representative’s office, or, with proper handling, entirely off-site. Field exams routinely include general ledger review, bank deposit analysis, tours of business premises (which a representative can and should manage), and expansion into related returns and years. This is where the stakes, the scope, and the value of seasoned representation are all at their maximum.

Technically no — and the distinction matters. A CP2000 comes from the Automated Underreporter (AUR) program, which matches the W-2s, 1099s, and other information returns in IRS systems against what you reported. It proposes changes by computer, not by examiner, and it is resolved through the AUR unit under IRM 4.19.3, not the examination rules. But treat it with full audit seriousness: an unanswered or badly answered CP2000 becomes a real assessment, complete with accuracy-related penalties, and a sloppy response that raises new questions can invite an actual examination. The same discipline applies — reconcile every line, respond in writing, concede what is correct, contest what is not, and address the penalty separately (AUR notices routinely propose the 20 percent accuracy penalty in situations where reasonable cause defeats it).

Tax examination is as old as the income tax itself. The Revenue Act of 1862 created the Bureau of Internal Revenue and a corps of assessors and collectors charged with verifying returns under the Civil War income tax. When the modern income tax arrived with the Sixteenth Amendment and the Revenue Act of 1913, examination grew with it; by the mid-twentieth century the Bureau — renamed the Internal Revenue Service in 1953 — had built the examiner classifications still recognizable today: office auditors and field revenue agents.

Two modern developments shape every audit you will face. The first is statistical selection. Beginning in the 1960s, the IRS built the Discriminant Function (DIF) system — a closely guarded scoring model, originally calibrated by the Taxpayer Compliance Measurement Program’s line-by-line research audits and today refreshed by National Research Program studies — that assigns every filed return a score predicting the likelihood that an examination would change it. High DIF scores feed classification, where human classifiers select returns and identify the issues worth examining. The second is the IRS Restructuring and Reform Act of 1998. RRA 98 reorganized the agency into taxpayer-focused divisions, codified and expanded taxpayer rights in examinations — including confirmation of audio-recording rights and representation rights under IRC §7521 — created the independent Office of Appeals structure taxpayers rely on today, and, together with the later Taxpayer First Act of 2019, entrenched the Taxpayer Bill of Rights (IRC §7803(a)(3)), which includes the right to challenge the IRS’s position and be heard, the right to appeal in an independent forum, and the right to retain representation.

The most recent chapter is the enforcement rebuild. After a decade of shrinking budgets drove audit coverage to historic lows — with field audit rates falling most sharply — funding legislation in 2022 financed a multi-year hiring and technology wave aimed explicitly at high-income individuals, large partnerships, corporations, and abusive-scheme promoters, alongside heavy compliance campaigns on pandemic-era credits such as the Employee Retention Credit. The practical meaning for taxpayers: examination activity is expanding from its lows, it is increasingly data-driven, and the returns being selected are selected for a reason someone can usually identify in advance.

IRC §7602 is the engine: authority to examine any books, papers, records, or other data relevant to a liability, to take testimony, and to issue administrative summonses when cooperation fails. Its reach is broad but not boundless — examinations must serve a legitimate purpose, and §7605(b) protects taxpayers from “unnecessary examination” and, importantly, from a second inspection of the same books for the same year without written notice from senior officials.

IRC §6501 sets the clock. The IRS generally has three years from the later of the filing date or the due date to assess additional tax. The window extends to six years where the return omits more than 25 percent of gross income (or overstates basis to the same effect), and there is no limit at all for a false or fraudulent return or where no return was filed. Understanding exactly which statute applies to each year — and whether to sign a Form 872 consent extending it — is one of the most consequential strategic decisions in any audit, and Part Seven-A treats it in depth.

IRC §§6212 and 6213 are the deficiency procedures — the taxpayer’s structural protection. Before assessing most income tax deficiencies, the IRS must issue a statutory Notice of Deficiency (the “90-day letter”), and the taxpayer then has 90 days (150 if abroad) to petition the United States Tax Court, where the case is heard before any payment is required. This pre-payment judicial forum is the backstop that gives every stage of audit negotiation its leverage.

IRC §7521 governs interviews: the right to record with advance notice, the right to be informed of the process and your rights, the right to representation, and the rule that an interview must be suspended if the taxpayer asks to consult a representative. IRC §7491 shifts the burden of proof to the IRS in court on factual issues where the taxpayer has produced credible evidence, maintained required records, and cooperated — a provision that quietly disciplines examiner overreach when a case is built properly from day one. And the Internal Revenue Manual, Part 4 (“Examining Process”) is the operational rulebook: IRM 4.10 covers examination technique — including IRM 4.10.3 on interviews and tours, IRM 4.10.4 on evidence and indirect income-reconstruction methods, and IRM 4.10.7 on issue resolution — while IRM 4.19 governs campus exams and AUR, IRM 4.13 governs audit reconsideration, and IRM Part 8 (especially IRM 8.6) governs how Appeals evaluates unagreed cases on the hazards of litigation. The IRM is not law, but examiners are bound to it in practice, and representation that cites it fluently gets a different quality of examination.

Selection is rarely random. The main channels, roughly in order of volume: DIF and related statistical scoring (your return’s deduction and loss patterns diverge from the norms for your income and industry); information-return mismatches feeding both AUR and exam classification; related and spin-off examinations (your business partner, your employer’s payroll case, a partnership you hold an interest in — partnership adjustments flow to partners); refundable-credit verification programs; specific compliance campaigns (digital assets, ERC claims, conservation easements, high-income non-filers); whistleblower referrals under IRC §7623; and a small stratum of pure research audits under the National Research Program. Within any of those channels, classifiers look for the patterns practitioners know well: Schedule C losses year after year against W-2 income, vehicle and meal deductions out of proportion to revenue, round numbers everywhere, hobby-loss profiles under IRC §183, large charitable deductions relative to income, rental losses claimed by taxpayers who do not qualify for the exceptions, unreported crypto activity, and cash-intensive businesses whose reported margins defy their industry. None of these items is improper when real and documented — the trigger is the pattern, and the defense is the paper.

Audits speak in form numbers, and knowing the vocabulary tells you exactly where you stand in the process:

The examiner’s first moves are scripted by IRM 4.10: review the classified issues, run internal research (prior audits, related returns, information documents, currency reports), and issue the opening IDR. Your first moves should be equally scripted, and in this order: engage representation and file Form 2848 before responding to anything substantive; obtain your own IRS transcripts — wage and income transcripts, account transcripts for open years — so you know exactly what the government already has; perform an honest self-audit of the return under examination, because you must know your weaknesses before the examiner finds them; and only then respond to the IDR, completely but precisely — answering what is asked, organized and indexed, and nothing more. The single most common unforced error in all of audit defense is the shoebox response: a disorganized mass of over-production that hands the examiner issues never classified and questions never asked.

Almost never, once represented. Under IRC §7521(c), the IRS generally cannot require a taxpayer to accompany a duly authorized representative to an interview absent an administrative summons — and summonses for routine exams are rare. Practitioners keep clients out of the room for a simple reason: the examiner’s interview questions are designed to establish income sources, lifestyle, cash habits, recordkeeping practice, and internal controls, and unprepared answers create adjustments and, occasionally, badges of fraud, out of thin air. A representative answers from the records, takes questions under advisement, and keeps the factual record clean. If you are ever interviewed directly, §7521 gives you the right to record with ten days’ notice, the right to stop the interview to consult a representative, and the right to a clear explanation of the process — rights that exist only for those who invoke them.

Because IRM 4.10.4 tells examiners to test income, not just deductions. The bank deposit method totals all deposits into all accounts, subtracts identified non-taxable items — transfers between accounts, loan proceeds, gifts, refunds, redeposits — and compares the remainder to reported gross receipts. A gap becomes proposed unreported income unless the taxpayer explains it. Related indirect methods authorized when records are inadequate include the source-and-application-of-funds method, the net worth method, and industry markup analyses, all resting on IRC §446(b)’s authority to compute income by any method that clearly reflects it. Two practitioner truths: first, deposits are not income — the law is clear that the analysis must remove non-taxable items, and a rigorous reconciliation prepared by your representative before the examiner runs their own version controls this issue rather than reacting to it; second, sloppy personal/business account commingling is the raw material of every inflated deposit analysis ever issued. Part Five works a full example with numbers.

Correspondence audits typically run three to nine months; office audits three to six months of active work; field audits of businesses commonly a year or more. The scope in years is governed by IRS policy and the statute: examiners generally start with one year, and IRM 4.10 directs them to consider the prior and subsequent year where the same issues likely recur. Expansion beyond that requires justification — and a representative’s scope-management job is to keep the audit inside its classified issues and its opened years unless expansion actually favors the taxpayer (occasionally it does, as when a favorable method change or loss carryback is in play). The assessment clock of IRC §6501 runs throughout, which is why examiners request Form 872 statute extensions as audits mature — a request that is a negotiation, covered in Part Seven-A, not an obligation.

Every proposed adjustment flows through your return’s actual mechanics, which is why identical adjustments cost different taxpayers very different amounts. A $40,000 disallowed Schedule C deduction does not just add $40,000 of taxable income at your bracket rate; it also increases self-employment tax, can shrink the qualified business income deduction, can phase out credits and deductions keyed to adjusted gross income, and can ripple into state tax through California’s FTB piggyback process (Part Seven-A). Competent representation always recomputes the full cascade before deciding which issues are worth fighting — some adjustments are cheaper to concede than to defend, and some “small” adjustments are secretly expensive.

– Accuracy-related penalty — IRC §6662: 20 percent of the underpayment attributable to negligence or disregard of rules, or to a substantial understatement — for individuals, an understatement exceeding the greater of 10 percent of the correct tax or $5,000. Certain valuation misstatements can push the rate to 40 percent. This is the default penalty on nearly every Form 4549, and it is the most defeatable number on the page.
– Civil fraud penalty — IRC §6663: 75 percent of the underpayment attributable to fraud, which the IRS must prove by clear and convincing evidence using the classic “badges of fraud” — understated income patterns, false records, concealment, dealing in cash, implausible explanations. Rare, but its mere consideration changes how a case must be handled (see eggshell audits, Part Seven-A). Fraud also eliminates the assessment statute entirely.
– Failure-to-file and failure-to-pay — IRC §6651: relevant when the audit involves delinquent or substitute returns — 5 percent per month (up to 25 percent) for late filing, 0.5 percent per month for late payment, with the file penalty reduced by the pay penalty when both apply, and a 75 percent fraud-failure-to-file variant in extreme cases.
– Information-return and foreign-reporting penalties: audits touching foreign accounts and assets can implicate FBAR penalties and IRC §6038-family penalties (Forms 5471, 3520, 8938) that dwarf the income tax itself — a specialty area where the first response letter matters enormously.
– Interest — IRC §6601: not a penalty and almost never abatable, running from the return’s original due date at the federal rate, compounded daily. On a three-year-old adjustment, interest routinely adds 20 to 30 percent to the bill — one more reason speed and issue-selection matter.

Two doctrines do most of the work. Reasonable cause under IRC §6664(c) defeats the accuracy penalty where the taxpayer acted in good faith — reliance on a competent professional who was given complete information, an honest and documented position on a genuinely uncertain question, records destroyed by circumstances beyond the taxpayer’s control. The defense is factual and must be argued, with evidence, item by item; examiners assert §6662 by default and concede it only when made to. Second, and little known: IRC §6751(b) requires written supervisory approval of most penalties before they are asserted, and penalties assessed without timely approval have been invalidated in a long line of Tax Court cases. Checking the administrative file for §6751(b) compliance is now standard practice in any well-defended audit — a purely procedural defense that has erased six-figure penalties. Penalty defense is not an afterthought to the audit; on many Form 4549s it is a quarter of the money.

First, fight it at the examiner level. Most audit money is won or lost before any appeal, in the rebuttal to the Form 886-A: a written, documented, authority-cited response to each proposed adjustment, escalated to the examiner’s group manager where the examiner will not move. Managers have real settlement incentive — unagreed cases are tracked — and a rigorous rebuttal frequently resolves half the issues on the spot.

Second, the 30-day letter and Appeals. When the case closes unagreed, Letter 525 gives you 30 days to request review by the IRS Independent Office of Appeals — via Form 12203 for disputes of $25,000 or less per period, or a formal written protest above that. Appeals is a different world from exam: Appeals Officers operate under IRM Part 8 (IRM 8.6 in particular), are independent of the examination function by statute since the Taxpayer First Act, and are explicitly authorized to settle based on the hazards of litigation — the probability the government would lose some or all of the issue in court. Exam decides what the rules say; Appeals prices risk. Cases that were stone walls at exam routinely settle at 30, 50, 70 cents on the issue in Appeals, and penalties are the single most commonly conceded item there.

Third, the 90-day letter and Tax Court. If Appeals fails or is skipped, the Statutory Notice of Deficiency issues under IRC §6212, and IRC §6213 gives you 90 days to petition the United States Tax Court — the only forum where you litigate before paying. Small tax cases ($50,000 or less per year) can elect simplified “S case” procedures. A little-known practical point: the vast majority of Tax Court petitions never see trial — docketed cases are referred back to Appeals for settlement, meaning a timely petition is often simply the price of a second, better-leveraged Appeals conference. Missing the 90 days, by contrast, forfeits pre-payment review entirely; the remaining routes are paying and suing for refund, or the administrative reconsideration below.

Fourth, audit reconsideration — the safety valve. Under IRM 4.13, a taxpayer who never had (or never used) the chance to present information — the audit notices went to an old address, the assessment came from an unanswered correspondence exam, new documentation has surfaced — may request reconsideration of the assessment. It is discretionary, it does not suspend collection by itself, and it requires genuinely new information; but it reverses bad default assessments every day, and it is the standard rescue for the taxpayer who arrives after the deadlines have all run.

Sometimes — but never reflexively, and never the open-ended Form 872-A without extraordinary reason. The calculus: refusing an extension forces the IRS to protect the statute by issuing the Notice of Deficiency on the evidence it has, which converts an unfinished audit into a Tax Court posture — sometimes good for you (the government’s half-built case meets the hazards analysis), sometimes bad (a bloated protective deficiency with every issue resolved against you, penalties included, and your leverage now spent on procedure). A restricted consent — limited in time and, where negotiable, limited to specified issues — frequently serves both sides. The decision requires knowing exactly how strong the remaining issues are and exactly how much time remains on §6501; it is, in miniature, the whole reason experienced IRS audit help exists.

An audit where the return contains a problem the examiner has not yet found — materially unreported income, fabricated deductions, a pattern that could be read as one of the badges of fraud catalogued in IRM 25.1. The taxpayer walks on eggshells: ordinary cooperation obligations collide with the Fifth Amendment and with the risk that the civil examiner develops “firm indications of fraud” and suspends the exam for referral to Criminal Investigation. Eggshell audits demand specialized handling — controlled responses, no volunteered interviews, careful privilege analysis, and sometimes the early involvement of tax counsel with the practitioner working under privilege arrangements. Two absolute rules for any taxpayer who recognizes themselves in this paragraph: never lie or produce altered documents to an examiner (the cover-up converts a money problem into a liberty problem), and never navigate it alone. The good news practitioners can honestly report: handled correctly, the overwhelming majority of eggshell audits resolve civilly.

IRC §7605(b) and the IRS’s repetitive-audit policy protect against exactly this: where the same items were examined in either of the two preceding years and produced no change (or a negligible one), the taxpayer can request that the current exam of those items be discontinued. It is invoked, not automatic — one more example of a right that exists only for those who raise it.

Employee Retention Credit claims are, at this writing, the single hottest examination category for small businesses — a predictable aftermath of the promoter industry that mass-filed aggressive claims. ERC exams focus on eligibility fundamentals: the governmental-order suspension test or the gross-receipts decline test, the qualified-wage computations, aggregation rules, and the interplay with PPP forgiveness. Businesses whose claims were prepared by percentage-fee promoters should have the file independently reviewed before the audit letter arrives — voluntary correction postures are dramatically better than examined ones, and the IRS has run withdrawal and disclosure programs for exactly this population. The same lesson generalizes: when the IRS announces a campaign (digital assets, easements, high-income non-filers), being in the announced population is itself notice to get the file audit-ready.

Effectively, yes — in results if not in process. California requires taxpayers to report final federal determinations to the FTB within six months, and the FTB receives federal adjustment data regardless; a federal RAR typically produces a piggyback state assessment, with California’s own (longer) statute rules applying to federal-change assessments. Strategy implication: the federal audit is where the war is fought, because every dollar defended federally is defended twice — and the state notice that follows a federal settlement must be reconciled against the actual federal outcome, since piggyback assessments are frequently computed wrong. Because Mike Habib, EA handles IRS, FTB, EDD, and CDTFA matters under one roof, the federal defense is built with the California consequence already on the board.

Mechanically the same, practically distinct: foreign-earned-income exclusion qualification (physical presence and bona fide residence tests) is a classic exam issue; information-return exposure (FBAR, Form 8938, Forms 5471/3520) often outweighs the income tax; currency translation and foreign records require early organization; and every deadline analysis must account for the 150-day deficiency-petition window for taxpayers abroad. Representation by a firm that regularly serves Americans overseas — as Mike Habib, EA does — removes the timezone-and-logistics tax from an already stressful process.

The audit-defense marketplace has its own version of the settlement mills: prepaid “audit protection” plans that assign whoever is available when the letter arrives, national call centers where a salesperson quotes a defense before anyone has read the notice, and preparers who offer to “handle it” for returns they prepared — with every incentive to defend their own work rather than your interests. The tells are consistent:

– A strategy quoted before anyone has read the actual notice, pulled your transcripts, or reviewed the return under exam. Audit defense is diagnosis first; anything else is a script.
– No named, credentialed practitioner on your Form 2848. If the company cannot tell you exactly which licensed individual will sign the power of attorney and appear before the examiner, you are buying a queue, not a representative.
– Guarantees. Nobody can guarantee an audit outcome — the honest promise is a process: transcript analysis, self-audit, scope control, documented rebuttal, and appeal when warranted.
– Advice to ignore the notice, hide records, or “explain it yourself first to save money.” Each of these is how small audits become large ones — Part Seven-B is a catalog of the wreckage.
– One-size responses. A correspondence exam over education credits and a field exam of a cash business are different disciplines; a firm that treats them identically understands neither.

The contrast worth stating plainly: legitimate representation begins with your specific notice, your specific transcripts, and your specific return — and tells you honestly when an issue should be conceded, because credibility spent defending the indefensible is credibility unavailable for the issues that can be won.

Low in the aggregate — well under one percent of individual returns in recent years — but averages mislead. Rates climb steeply with income, with refundable-credit claims, with Schedule C losses, and with membership in an announced campaign population. The useful question is never the national rate; it is whether your return contains the patterns classifiers select — and if it does, whether the documentation exists to defend them.

Generally three years from filing under IRC §6501; six years where gross income was understated by more than 25 percent; without limit for fraud or for years never filed. Practically, most exams cover one to three years — and keeping records at least seven years covers the realistic exposure for most taxpayers.

Almost certainly not. Civil examinations and criminal prosecutions are different universes; criminal tax cases are rare and reserved for willful, provable misconduct. What converts civil problems toward the criminal boundary is nearly always conduct during the audit — false statements, fabricated documents, concealment. Tell your representative everything, tell the IRS nothing false, and even genuinely bad returns resolve as money problems.

A single-item correspondence audit with clean documentation is the strongest do-it-yourself candidate — and even there, unrepresented taxpayers routinely pay asserted penalties that reasonable cause defeats, miss the 30-day Appeals window, and over-produce their way into expanded exams. The honest framing: weigh the cost of representation against the full exposure — tax cascade, penalties, interest, year expansion, and the state piggyback — not against the notice’s face amount.

Reconstruction is legitimate and often successful: bank and card statements, vendor reprints, calendars, mileage rebuilt from job records, and reasonable estimation under the Cohan doctrine for categories where courts allow it (vehicle, travel, and meal expenses carry stricter statutory substantiation rules under §274(d)). What is never legitimate is presenting recreated records as contemporaneous originals. Disclosed reconstruction persuades; disguised reconstruction destroys.

It means the auditor is professional. Rapport is an interview technique — the comfortable conversation is where income sources, cash habits, and lifestyle details surface. Be courteous, be honest, and route the substance through your representative; friendliness is free, and so are the adjustments it produces.

Yes, with justification — recurring issues support opening the prior and subsequent year, and flow-through entities put related returns in reach. Scope management is a core representation function: expansion requests are met with the IRM’s own standards, and nothing in your responses should volunteer the invitation.

A no-change letter closes the examined year as filed — a genuinely good outcome — and triggers the repetitive-audit protection for the same items in the near term. It does not immunize other years or other issues, but as a practical matter, a clean exam materially lowers your near-term selection profile.

Sometimes — a remittance designated as a deposit under IRC §6603 stops the interest clock without conceding the issue, and can be returned if you prevail. It is a cash-flow and confidence decision, made issue by issue, and it should never be confused with signing the report.

The examination and the collection of its result are separate battles with separate tools: installment agreements, hardship status, penalty abatement, and — where the math supports it — the Offer in Compromise, which the companion guide in this series covers in depth. The worst plan is silence; assessed balances left unattended mature into liens and levies on a timetable that never misses its deadlines even when taxpayers miss theirs.

Extensions do not — an extended return is scored like any other, and a rushed, error-laden April return is far riskier than an accurate October one. Amended returns receive their own review, and large refund claims on amendments get genuine scrutiny (very large ones are reviewed by the Joint Committee process), so amendments should be as bulletproof as originals. Refunds themselves are not triggers; the items generating them — refundable credits, big loss carrybacks — can be. The stable rule across all three: risk follows the content of the return, not the calendar of its filing.

Confusing the three causes real strategic errors. A Revenue Agent examines returns in the field — the most trained examiner class, handling business and complex individual audits. A Tax Compliance Officer conducts office audits of individual returns. A Revenue Officer is not an auditor at all: ROs collect assessed debts — levies, liens, seizures — and arrive after a liability exists. If a Revenue Officer is at your door, the audit conversation is over and the collection conversation has begun, with an entirely different rulebook and entirely different defenses.

It can examine barred years for their effect on open years — verifying a loss or credit carryforward that originated in a closed year, for example, and adjusting the carryover as it lands in the year still open under §6501. It cannot assess the closed year itself absent fraud or a statute exception. Carryforward-heavy returns (NOLs, capital losses, passive losses, credit carryovers) should therefore retain origin-year documentation for as long as the carryforward lives, plus the open-statute tail — a records-retention rule that surprises nearly everyone it bites.

Less than you probably assume. The federally authorized tax practitioner privilege of IRC §7525 covers tax advice from EAs and CPAs in noncriminal proceedings, but it contains significant exceptions and does not shield return-preparation materials — and no accountant-client privilege exists at all in criminal matters, where only attorney-client privilege (sometimes extended to accountants working under counsel through a Kovel arrangement) protects communications. Practical translation: sensitive facts belong in privileged channels from the beginning, and an eggshell-flavored audit is the moment to structure them that way, not after the summons arrives.

Run three numbers, issue by issue: the full-cascade cost of losing (tax, self-employment tax, credit phase-outs, penalty, interest, and the state piggyback), the realistic probability of winning given the evidence you actually hold, and the cost — in fees, time, and credibility — of the fight. Some issues are cheap to concede and poisonous to defend; others look small on the Form 4549 and are worth a protest because the same issue recurs on every future return. This triage is the strategic heart of audit representation, and it is why the first week of an engagement is spent on diagnosis rather than combat.

Mostly to advertising, which is why this guide exists. Real IRS audit help has a recognizable shape: a licensed practitioner personally named on your power of attorney, a diagnosis built from your transcripts and your return before any strategy is quoted, scope discipline during the exam, written advocacy on every material issue, penalty defense on both facts and procedure, and a representative who can carry the case through Appeals if the examiner will not move. Measure anyone offering audit help — including this firm — against that checklist.
