Answer an IRS notice with a reconciled, ready-to-sign response

Traditional vs AI-native

The traditional way

1. Client emails a phone photo of a notice (often weeks after its date) or it arrives by mail under the firm's CAF number.
2. A senior person reads it to work out what it is: a matching notice (CP2000), a balance due (CP14, CP501/503/504), a math error (CP11/CP12), a levy notice (LT11 / Letter 1058), an identity verification letter (5071C), or a state equivalent.
3. Someone pulls the filed return, the source documents, and last year's correspondence to see whether the IRS is right.
4. The preparer rebuilds the IRS's math by hand and compares it to Schedule D, Form 8949, or the relevant schedule.
5. A response letter is written from scratch or adapted from an old one, exhibits are assembled, and Form 2848 status is checked.
6. Penalty relief is often forgotten, or requested inconsistently depending on who handles the file.

Where it hurts

• Response deadlines are missed because the notice sat in a client's inbox or nobody calendared it from the notice date.
• Senior time goes to identifying and reconciling routine notices instead of actual controversy judgment.
• Clients pay CP2000 proposed amounts that were wrong because the review was rushed.
• First-Time Abate is left on the table for eligible clients.

The AI-native way

1. 1Automation

   Capture the notice and link it to the client

   Notices arrive through a portal upload, a scanned mail batch, or an email-to-folder address. Each file is queued with a client match based on name, SSN/EIN last four, and address, and unmatched notices go to an admin queue. The original image is stored as the evidence copy, and nothing downstream edits it.

2. 2AI

   Identify the notice and extract its key fields

   A vision-capable model reads the notice number (usually printed in the upper or lower right corner), tax year or period, form, notice date, amounts proposed or due, the response-by date if printed, the IRS unit, phone number, and fax or mailing address. It returns strict JSON with the page and region each value came from. If the notice number can't be read, or the notice isn't in the firm's library of known notices, it goes to a human instead of being guessed.

3. 3Automation

   Calendar the deadline and open a task

   Deadlines are computed by code, not the model. A rules table maps each notice type to its response window: the printed response date where there is one, 30 days from the notice date for a CP2000, 30 days to request a Collection Due Process hearing after an LT11 / Letter 1058, 60 days to request abatement of a math-error adjustment, and 90 days to petition the Tax Court after a statutory notice of deficiency. The practice management task gets the notice, the client, the deadline, an internal target date a week earlier, and the assigned representative.

4. 4Automation

   Check authorization before anyone calls

   The system checks the firm's Form 2848 register (or a Tax Pro Account / CAF export) for a power of attorney covering the tax matter, form, and year on the notice. If there's no valid 2848, a pre-filled draft is queued for client e-signature. A Form 8821 alone lets the firm get information but not represent the client or advocate for them.

5. 5AI

   Reconcile the proposed change against the filed return

   For a CP2000, the model lines up each information return the IRS lists against where it was (or wasn't) reported on the filed return and in the source documents. Common findings: 1099-B proceeds the IRS treated as zero-basis when the basis was actually reported on Form 8949 with box B or E checked; the same income counted twice (a 1099-NEC also included in W-2 wages, or a 1099-K duplicating 1099-NEC receipts); nominee income belonging to someone else; and 1099-R rollovers the IRS treated as taxable. Code recomputes every dollar figure, and the model only explains the differences.

6. 6AI

   Decide the response position and draft the package

   For each item the model proposes agree, partially agree, or disagree, with the evidence behind it. It drafts the response letter in the IRS's format (notice number, tax year, taxpayer ID last four, a clear statement of position, and an item-by-item explanation), fills in the notice's response form, and lists the exhibits in order (8949 page, broker supplemental basis statement, nominee statement). For balance-due notices it drafts payment options or a hold request instead.

   Screen for penalty relief

   For 2025 and later returns, the rules check first asks whether the IRS's Automatic Exemption from Penalty (which begins in summer 2026) should already have kept the penalty from being assessed. If not, it tests First-Time Abate eligibility under IRM 20.1.1.3.3.2.1: the penalty must be failure-to-file, failure-to-pay, or failure-to-deposit; the same return type must have been timely filed for the prior three years; and no penalty other than the estimated tax penalty may have been assessed in that window unless it was later abated for reasonable cause or IRS error. Prior-year penalty history comes from the account transcript. If the client qualifies, the model drafts a phone script for the practitioner priority line or a Form 843. If not, it drafts a reasonable cause narrative from the facts the client gives, and it never invents circumstances.

   Representative review and sign-off

   The representative sees the notice image, the extracted fields, the reconciliation table, the draft letter, the exhibits, and the penalty recommendation side by side. They confirm the position, edit the letter, and approve how it will be sent (fax, mail with certified receipt, or the IRS's online document upload where the notice allows it). Nothing goes to the IRS or a state agency without this step, and every edit is logged.

9. 9Automation

   Send, track, and follow up

   Once it's sent, the proof of mailing or fax confirmation is attached to the task and a follow-up reminder is set (for example, 60 days out, to check the account transcript for resolution). If a later notice on the same issue arrives, it's linked to the same matter so the history stays in one place.

What you need

• The notice (a scan or phone photo is fine)
• The filed return and source documents in your file
• A Form 2848 on file for the tax, form, and year
• A deadline rules table by notice type
• An enterprise AI tool under no-training data terms

Copy the prompt

You are a senior tax representative at a CPA firm analyzing an IRS CP2000 (proposed adjustment from information-return matching). You will receive:
1. NOTICE: JSON extracted from the CP2000 (tax year, notice date, each information return the IRS lists with payer, form, and amount, and the proposed tax, penalty, and interest).
2. RETURN: JSON export of the filed return lines and schedules (including Form 8949 rows with the box checked, Schedule C gross receipts, and 1099-R treatment).
3. SOURCE_DOCS: JSON list of the source documents in the file (form, payer, amounts, and any supplemental statements).

Tasks:
A. For each item the IRS lists, find where it was reported on RETURN, if anywhere. Classify it as: reported_correctly, reported_elsewhere, basis_omitted_by_irs, duplicate, nominee, nontaxable_rollover, truly_unreported, or needs_client_info.
B. For basis_omitted_by_irs: cite the Form 8949 box (B or E) and the basis amount from RETURN or SOURCE_DOCS.
C. Recommend an overall position: agree, partially_agree, or disagree. Explain it in two sentences.
D. List the exhibits needed for each disputed item, and name the specific document from SOURCE_DOCS.
E. Draft a response letter under 400 words: the notice number, tax year, and taxpayer ID last four only; a clear statement of position; an item-by-item explanation; and the exhibit list. Use a professional, non-argumentative tone.
F. Flag for the reviewer any accuracy-related penalty the notice proposes, and whether the facts suggest a reasonable-cause argument. Do not assert facts that aren't in the input.

Rules:
- Never invent an amount, payer, document, or date. If you need a number that isn't in the input, write "UNKNOWN" and add it to open_questions.
- Do not do final arithmetic. Report the figures as they appear in the input, and set recompute_required to true for any item whose tax effect changes.
- Do not cite any IRC section, regulation, or IRM provision unless it is given in the input.
- If the evidence for an item is ambiguous, classify it as needs_client_info rather than choosing a side.

Output JSON:
{ items: [{ irs_item, classification, return_reference, evidence, recompute_required }],
  position: "", position_reason: "", exhibits: [], penalty_flags: [],
  open_questions: [], draft_letter: "" }

Guardrails

• Run notices and returns only through an enterprise AI tier under a data processing agreement with no training on firm data and zero or minimal retention. Record the workflow in the firm's WISP as the FTC Safeguards Rule requires.
• If your firm prepared the return, using that return information to respond to the IRS for the client is generally permitted without separate consent: Treas. Reg. §301.7216-2(b) exempts disclosures to the IRS, and §301.7216-2(m) covers use in an IRS examination. Confirm the IRC §7216 analysis with counsel before routing data to any new third-party service, and when the return was prepared elsewhere.
• Check Form 2848 coverage for the specific tax, form, and year before anyone contacts the IRS. A Form 8821 alone doesn't authorize representation.
• Deadlines come from a rules table keyed to the notice type and the notice date, not from the model's reading of the notice. The earliest plausible deadline wins when there's doubt.
• Circular 230 §10.22 due diligence applies to every factual statement in the letter. The representative confirms each exhibit supports what the letter says it does.
• FTA and reasonable cause narratives use only facts the client has confirmed in writing. The model is instructed never to invent hardship, illness, or reliance facts.

What can go wrong

How to prove it worked

Where this goes

Notices stop being fire drills. Combined with monthly transcript monitoring, the firm often knows about an adjustment before the letter arrives, has the reconciliation ready, and calls the client with an answer instead of a question. Notice response becomes a packaged, fixed-fee service that a small team can deliver at volume without burning out its senior people.
