The Individual Tax Controversy Toolkit

Tax > Tax Controversy | Published 25 June 2026 - Updated 28 August 2026 | UpLaw - uplaw.us

Module 1 fits on an index card. It takes about a minute per envelope and it is the difference between a tax problem and a tax catastrophe.

Keywords: triage, transcripts, examination, Appeals, deficiency, CDP, levy, offers, penalties

Module 1 — The notice triage card

For each letter, in order:

1. Does it say "Notice of Deficiency" or mention the Tax Court? → 90 DAYS. 26 U.S.C. § 6213. Calendar it in three places today. Nothing extends it.

2. Does it say "final notice," "intent to levy," and mention a hearing right? → 30 DAYS. 26 U.S.C. § 6330. File the request by certified mail.

3. Does it announce that a notice of federal tax lien was filed, with a hearing right? → 30 DAYS. 26 U.S.C. § 6320. Same.

4. Is it an examination report? → 30 days to protest to Appeals. Skipping it produces a deficiency notice.

5. Does it propose a change and invite a response? → 30 days. This is a conversation. Answer it with documents.

6. Is it a balance due notice? → No right is forfeited, but collection is running. Arrange something.

7. Anything else? → Read it, keep it, file it.

Only rows 1, 2, and 3 forfeit a right that cannot be recovered. Everything else is repairable at some cost.

Module 2 — Transcript worksheet

Pull account, wage and income, and return transcripts for every year, plus two on either side.

Year	Return filed?	SFR?	Assessment date	CSED	Deficiency notice issued?	Penalties	Balance

What each column decides.

Return filed — an unfiled year has no running assessment period under 26 U.S.C. § 6501. It never expires.

SFR — a substitute for return under 26 U.S.C. § 6020 allows no deductions the agency does not know about. Filing the real return is usually the largest single reduction available in the whole case.

Assessment date — the lien under 26 U.S.C. § 6321 dates from here per 26 U.S.C. § 6322, and the collection period under 26 U.S.C. § 6502 runs from here.

CSED — the collection statute expiration date. Compute it before taking any action that suspends it.

Deficiency notice issued — determines whether the underlying liability may be challenged at a CDP hearing at all.

Module 3 — Examination response template

Re: [taxpayer] · TIN [] · Tax year [] · Examination of [items]

Enclosed is the taxpayer's response, indexed to your letter of [date].

Item 1 — [restate the request verbatim]. Response: [describe]. Tab A. Item 2 — [restate]. Response: [describe]. Tab B. Item 3 — [restate], records not maintained in the requested form. The enclosed reconstruction at Tab C is derived from [bank statements / calendar / appointment records / vendor confirmations], which are contemporaneous business records, together with a statement of the method used.

All documents are copies; originals are available for inspection. A complete index appears at Tab [___].

If further information would assist, please identify it specifically and I will respond.

Five rules that go with the template.

Answer only what is asked. Scope expands through volunteered information, not through examiner decisions.

Copies with an index, never originals, with a log of what was sent and when.

Reconstruct rather than estimate. An unsupported estimate invites an accuracy penalty under 26 U.S.C. § 6662.

Extensions in writing, before the deadline.

Preserve the burden-shift conditions of 26 U.S.C. § 7491 — credible evidence, maintained records, and cooperation. Obstruction forfeits a statutory advantage.

The examination authority itself is 26 U.S.C. § 7602; the right to suspend an interview to consult a representative is among those enumerated in 26 U.S.C. § 7803.

---

Module 4 — Appeals protest outline

I. Identification. Taxpayer, TIN, years, the examination report and its date.

II. Statement of agreement. What is not disputed. Conceding clearly makes the rest credible.

III. Findings disputed. Each one, by item and amount.

IV. Facts. Chronological, specific, and supported by tabbed documents.

V. Law and authority. The Code sections, regulations, and cases relied on.

VI. Hazards of litigation. This is the section that distinguishes an Appeals protest from an examination response. Appeals may settle for less than the full amount because the government might lose. Say why it might lose, specifically.

VII. Proposed resolution. With numbers.

VIII. Index of exhibits.

Why the sixth section matters. An examiner applies the agency's reading of the law. Appeals is authorized to weigh the probability of the government losing — a fundamentally different conversation, and the reason most cases that reach Appeals resolve there.

Module 5 — Collection due process request

Re: [taxpayer] · TIN [] · Tax periods [] · Notice dated [___]

I request a Collection Due Process hearing under 26 U.S.C. § 6330 [and 26 U.S.C. § 6320]. This request is timely, being made within thirty days of the notice.

Issues to be considered:

1. Collection alternatives, specifically [installment agreement at $___ per month / offer in compromise / currently not collectible status]. A completed financial statement is enclosed.
2. Whether the proposed collection action balances the need for efficient collection against the taxpayer's legitimate concern that any collection action be no more intrusive than necessary.
3. Spousal defenses under 26 U.S.C. § 6015.
4. Whether all requirements of applicable law and administrative procedure were met.
5. [Where applicable] The underlying liability. The taxpayer did not receive a notice of deficiency for these periods and has had no prior opportunity to dispute the liability.

The taxpayer requests a face-to-face hearing and reserves all issues for review.

Send by certified mail and keep the receipt. A timely request suspends levy action and suspends the collection statute under 26 U.S.C. § 6502. That suspension is a real trade-off — make it deliberately.

A late request produces an equivalent hearing: same issues, no judicial review, no statute suspension.

---

Module 6 — Levy release letter

Send today. A bank levy has a short holding period before the funds are remitted.

Re: [taxpayer] · TIN [___] · Levy served on [bank / employer] on [date]

I request immediate release of this levy under 26 U.S.C. § 6343, on the ground that it is creating an economic hardship.

The enclosed financial statement shows monthly income of $[] against necessary living expenses of $[]. The levied funds are required for [rent or mortgage · utilities · food · medical care · transportation to work].

[Where applicable] Portions of the levied account belong to [non-liable party], as shown at Tab [___].

[Where applicable] Certain property levied is exempt under 26 U.S.C. § 6334.

The taxpayer is prepared to enter an installment agreement at $[___] per month and requests that release be conditioned on that agreement.

Please confirm release in writing to the levy source and to me today.

Then, in order: confirm by phone the same day · escalate to a manager if not resolved · escalate to the Taxpayer Advocate Service where hardship is significant · and consider whether the collection conduct supports an action under 26 U.S.C. § 7433.

Distinguish the two levy types. A bank levy is a one-time snapshot with a holding period. A wage levy is continuous and attaches to every payment until released. Authority for both is 26 U.S.C. § 6331.

Module 7 — Reasonable collection potential calculator

Run this before deciding whether an offer is worth preparing. An offer below this figure will not be accepted, regardless of the circumstances.

A. Net realizable equity in assets

Asset	FMV	× quick-sale %	Less encumbrance	Net
Real property
Vehicles
Bank and investment accounts
Retirement accounts
Business assets
Other
Subtotal A				$______

B. Future income

	Monthly
Gross income (all sources)	$______
Less allowable living expenses	$______
Monthly disposable income	$______
× applicable multiple	______
Subtotal B	$______

Reasonable collection potential = A + B = $__________

Compare to the total liability.

If RCP ≥ liability → an offer will not be accepted. Use an installment agreement. If RCP < liability → an offer under 26 U.S.C. § 7122 is worth preparing. If monthly disposable income ≈ 0 and assets are minimal → currently not collectible is likely the right answer, and it must be requested by name. If full payment within the remaining collection period is impossible → consider a partial payment installment agreement.

Two cautions. A pending offer suspends the collection statute. Fees and initial payments are generally not refundable.

And one prerequisite that blocks everything: no alternative is available while returns are unfiled. Compliance first, always.

Module 8 — Penalty abatement letters, in order

First: first-time abatement

Re: [taxpayer] · TIN [] · Tax year []

The taxpayer requests first-time abatement of the [failure to file / failure to pay / failure to deposit] penalty under the administrative waiver. The taxpayer has no penalties assessed for the three preceding tax years, as the enclosed account transcripts confirm, and is current in filing and payment obligations.

Ask for this first. It requires establishing nothing. Writing a reasonable cause letter first wastes the easier remedy.

Second: reasonable cause

Re: [taxpayer] · TIN [] · Tax year []

The taxpayer requests abatement for reasonable cause under 26 U.S.C. § 6651.

[Facts: hospitalization from [date] to [date], records at Tab A · death of [relative] on [date], certificate at Tab B · destruction of records by [event], documentation at Tab C · written advice from the IRS dated [date], at Tab D.]

The taxpayer exercised ordinary business care and prudence and was nevertheless unable to comply. Compliance was restored on [date], as soon as the circumstances permitted.

The limit to know: United States v. Boyle, 469 U.S. 241 (1985) holds that reliance on an agent to file on time is not reasonable cause. Boyle distinguishes reliance on professional advice about a substantive question — which can be reasonable cause — from reliance on a professional to perform a ministerial act, which is not.

On interest

Interest under 26 U.S.C. § 6601, at rates set by 26 U.S.C. § 6621, is generally not abated merely because the tax was. 26 U.S.C. § 6404 permits abatement in narrow circumstances including certain unreasonable agency delays. Set the expectation early.

Module 9 — Innocent spouse screen

1. Was the return a joint return? 26 U.S.C. § 6013 makes the liability joint and several. ☐ Yes ☐ No 2. Is the understatement attributable to the other spouse's item? ☐ Yes ☐ No 3. Did the requesting spouse know or have reason to know? ☐ Yes ☐ No 4. Current marital status: ☐ married ☐ divorced ☐ separated ☐ widowed ☐ not in same household for 12 months 5. Economic hardship if held liable? ☐ Yes ☐ No 6. Significant benefit received? ☐ Yes ☐ No 7. Abuse or financial control by the other spouse? ☐ Yes ☐ No — weighed seriously and frequently dispositive 8. Compliance since? ☐ Yes ☐ No 9. Route: ☐ innocent spouse ☐ separation of liability ☐ equitable relief — all under 26 U.S.C. § 6015 10. Is this really an injured spouse claim? — recovering a joint refund offset under 26 U.S.C. § 6402 for one spouse's separate debt. Different remedy entirely.

SAFETY: the non-requesting spouse is notified and may participate. ☐ Discussed with client before filing on: ______

A divorce decree allocating tax debts binds the spouses. It does not bind the IRS, which may collect the whole amount from either.

Line 10 catches a surprising number of cases that were framed as innocent spouse problems and are actually offset problems with a much simpler answer.

Module 10 — Lien remedy selector

A lien arises automatically under 26 U.S.C. § 6321, dates from assessment under 26 U.S.C. § 6322, and gains priority against other creditors only on filing of a public notice under 26 U.S.C. § 6323.

Goal	Remedy	Typical basis
The debt is paid or unenforceable	Release	Satisfaction; expiration of the collection period
Sell one property	Discharge	The government's interest is protected or valueless
Refinance	Subordination	The refinancing will produce funds for the government
Remove the public notice while the debt remains	Withdrawal	Entry into a direct debit installment agreement; withdrawal facilitates collection

Withdrawal is the underused one. It removes the public record — the thing that actually damages credit, complicates a sale, and shows up when anyone looks. It is available in circumstances that arise routinely and it is granted on request.

---

Module 11 — Statute of limitations tracker

Period	Statute	Length	Watch for
Assessment	26 U.S.C. § 6501	3 years from filing	Extended for substantial omission; unlimited with no return or fraud
Collection	26 U.S.C. § 6502	10 years from assessment	Suspended by pending offer, timely CDP request, bankruptcy
Refund claim	26 U.S.C. § 6511	3 years from filing / 2 from payment	Look-back limits the recoverable amount
Refund suit	26 U.S.C. § 6532	2 years from disallowance	—
Tax Court petition	26 U.S.C. § 6213	90 days	Nothing extends it
CDP request	26 U.S.C. § 6320 · § 6330	30 days	Late becomes an equivalent hearing

Compute the CSED from the transcript before taking any action that suspends it. An old assessment approaching the end of its collection period changes the entire calculus — and an offer filed at the wrong moment can hand the government years it was about to lose.

---

Module 12 — Record retention card

Record	Keep for
Filed returns	Permanently
Supporting income and deduction records	7 years
Property purchase and improvement records	Until 7 years after disposition
Carryforward support	Life of the carryforward + 7
Employment tax records	At least 4 years after due or paid
Any year with no return filed	Permanently
Notices received from the IRS	Permanently
Proof of payment	Permanently
Account transcripts	Pull annually; keep

The notices row decides CDP cases. Whether a taxpayer previously received a notice of deficiency determines whether the underlying liability may be challenged at a hearing under 26 U.S.C. § 6330. A taxpayer who kept the envelopes can prove what arrived. One who did not is arguing about a mailing.

Module 13 — When it stops being administrative

Three signals require an immediate change of posture and the involvement of counsel.

A special agent makes contact. Criminal investigation, not examination.

The questions concern a specific false statement rather than a computational or documentary issue.

Badges of fraud appear — a second set of books, concealed accounts, destroyed or altered records, consistently large omissions, or an unexplained pattern.

The criminal provisions: 26 U.S.C. § 7203 makes willful failure to file, pay, or supply information a misdemeanor; 26 U.S.C. § 7206 makes a willfully false return, or aiding in one, a felony.

Willfulness is the voluntary, intentional violation of a known legal duty. Inability to pay is not willfulness. Confusion is not willfulness. The overwhelming majority of individual tax problems are administrative from beginning to end — and saying so plainly to a frightened client is frequently the most useful thing in this toolkit.

But when a signal appears, the privilege question becomes decisive. Only the attorney-client privilege covers criminal matters; the limited practitioner confidentiality available to CPAs and enrolled agents does not.

Equivalent hearing — the late version, without judicial review. RCP — reasonable collection potential, the arithmetic that decides an offer. CNC — currently not collectible. FTA — first-time abatement. Withdrawal — removal of a public lien notice while the debt remains.

Module 16 — Adjacent problems a tax file usually contains

A tax controversy is rarely the only thing wrong, and five neighbors show up often enough to screen for at intake.

Insolvency. Some tax debts are dischargeable in bankruptcy and many are not; the rules turn on the age of the liability, when the return was filed, and when the tax was assessed. An old, filed, assessed, non-fraudulent income tax has options that a recent employment tax liability does not. See Bankruptcy Law: A Comprehensive Guide to Chapters 7, 11, and 13 and The Bankruptcy and Restructuring Toolkit.

A failing business. Where the liability is employment tax, the exposure follows the individual under 26 U.S.C. § 6672 regardless of the entity. Winding down does not end it. Entity questions are covered in Business Taxation: A Comprehensive Guide to Entity Choice and Federal Income Tax, with the S corporation rules at 26 U.S.C. § 1361 and classification generally at 26 U.S.C. § 7701.

A divorce. A decree allocating tax debt binds the spouses and not the agency. Screen 26 U.S.C. § 6015 in every case involving a joint year, and coordinate with Child Custody and Support: A Comprehensive Guide to Parenting Plans, Guidelines, Modification, and Enforcement and The Child Custody and Support Toolkit where support is involved.

Identity theft. A return filed by someone else produces an unresolvable mismatch and a parallel credit problem. The tax remedy and the credit remedy are separate processes — see Consumer Credit Reporting and Debt Collection: A Comprehensive Guide to the FCRA, FDCPA, and Identity Theft Remedies.

A judgment. Where a refund was offset under 26 U.S.C. § 6402 to satisfy someone else's judgment or a spouse's separate debt, the remedy may be an injured spouse allocation rather than anything in the tax file. See Enforcing a Money Judgment: A Comprehensive Guide to Discovery, Liens, Levy, and Fraudulent Transfer.

The intake question that catches all five: what else is going on financially? — asked before the notices are sorted, not after.

---

Module 17 — Practice notes by role

For the taxpayer. Module 1 on every envelope. File even when you cannot pay — the failure-to-file penalty is much larger, and an unfiled year never expires under 26 U.S.C. § 6501. Keep the agency's address current, because a deficiency notice mailed to the last known address is valid whether or not you receive it.

For a general practitioner. Modules 1, 2, and 6 are within any careful lawyer's competence and account for most of the value. The two irreparable deadlines are ninety days and thirty days; everything else can be repaired.

For a representative in a collection case. Compliance first. Then Module 7's arithmetic. Then choose the alternative — understanding which options suspend the collection statute under 26 U.S.C. § 6502.

For a return preparer whose work is under examination. Name the conflict out loud. The client is entitled to know that preparer penalties exist and that your interest may diverge from theirs.

For anyone facing a levy today. Module 6, this morning, by phone, confirmed in writing.
