Engaging a tax professional to handle a CP2000 response is a financial decision that should be made with clear information. The initial consultation is your opportunity to evaluate whether the practitioner has the right experience for your matter.

This will include things like whether the fee structure is reasonable, what the scope of services actually covers, and whether the working relationship will be effective.

This article provides a complete set of questions organized by category – credentials and experience, pricing, scope of services, and process – so you can evaluate any professional you speak with using a consistent framework.

Questions About Credentials and Qualifications

“What is your credential, and how does it authorize you to represent me before the IRS?”

This establishes whether the practitioner is an Enrolled Agent, a CPA, or a tax attorney, and what their IRS authorization covers. Enrolled Agents are licensed by the IRS for all administrative proceedings. CPAs and attorneys are also authorized to represent clients before the IRS but through different authorization pathways. A practitioner who cannot answer this clearly does not have the baseline qualifications you need.

“How many CP2000 responses have you prepared or represented clients on?”

Volume of experience in this specific area matters. A practitioner who has handled dozens of CP2000 matters has seen the range of outcomes and common IRS objections. One who has handled only a few may be technically capable but will take longer and be less confident in navigating the specific procedural requirements of the AUR process.

“Do you have experience with the type of discrepancy in my notice?”

CP2000 discrepancies vary significantly in type. Investment basis reconstruction, Form 8606 IRA basis issues, Section 121 home sale exclusions, and Schedule C income matching are all different areas. A practitioner with specific experience in your discrepancy type will be more efficient and more effective than one who handles your type of matter for the first time. Ask directly whether they have handled similar issues and what the outcomes looked like.

“Are your credentials in good standing, and where can I verify them?”

Any credentialed professional should immediately provide a direct answer to this question: the IRS directory at irs.gov/taxpros for EAs, the relevant state CPA board for CPAs, or the state bar association for attorneys. If a practitioner is evasive about credential verification, do not proceed with the engagement.

“If my matter escalates to a Notice of Deficiency or Tax Court, are you authorized to represent me at those stages?”

EAs and CPAs can represent clients in all IRS administrative proceedings, including Appeals. They cannot represent clients in Tax Court unless they hold a separate Tax Court admission. Tax attorneys with the appropriate admission can. Knowing this boundary in advance helps you understand whether you might need to add or switch representation if the matter escalates.

Questions About Pricing and Fee Structure

“Do you charge a flat fee or hourly for CP2000 matters, and what is your rate?”

This is the foundational pricing question. Get the answer in specific terms – not “it depends” but an actual rate or range. If hourly, ask for a time estimate. If flat fee, ask exactly what the flat fee covers.

“What is included in your fee, and what would be charged separately?”

Common exclusions from flat-fee CP2000 engagements include additional rounds of IRS correspondence beyond the first, preparation of an amended return, penalty abatement requests as a separate service, transcript retrieval, and Appeals or Tax Court representation. Know the boundaries before signing.

“What happens to the fee if the IRS issues a follow-up notice or a Notice of Deficiency?”

Escalation changes the scope of the engagement. Clarify whether escalation events trigger additional flat fees, shift to hourly billing, or are covered under the original fee. A practitioner who cannot answer this clearly is not operating with a well-defined fee structure.

“Is the initial consultation fee charged, and if so, does it apply toward the engagement fee?”

Some practitioners charge for consultations; others offer them free. If charged, it is reasonable to ask whether the fee is credited toward the engagement. This is a minor point financially but signals how the practitioner treats clients from the outset.

“Will I receive an itemized billing statement so I can see how time is being spent?”

For hourly engagements, itemized billing gives you a basis for evaluating whether the time investment is reasonable. It also gives you early notice if the matter is taking significantly longer than estimated.

Questions About the Scope of Services

“Will you handle all IRS correspondence related to this matter, or only the initial response?”

Confirm whether the engagement covers the full lifecycle of the CP2000 or only the first submission. If the IRS responds with a revised notice or additional questions, knowing in advance whether your professional will handle it – and at what cost – prevents confusion later.

“Will you request a Power of Attorney so you can communicate directly with the IRS on my behalf?”

Full representation requires a Form 2848 Power of Attorney, which authorizes the practitioner to receive IRS correspondence, speak with IRS agents, and submit documents on your behalf. Confirm that this is part of the engagement. Without a Form 2848, the practitioner is an advisor, not a representative, and the IRS will continue communicating with you directly.

“Will you handle a penalty abatement request if one is appropriate?”

First-Time Abatement and reasonable cause penalty abatement are valuable tools that should be evaluated in any CP2000 engagement where the accuracy-related penalty is proposed. Confirm whether your practitioner will assess penalty abatement eligibility and include an abatement request in the response if warranted, or whether this is a separate service.

“What happens if the IRS rejects my response? What are the next steps and what will they cost?”

A realistic professional will explain the Appeals process, the Notice of Deficiency timeline, and the Tax Court option as contingencies. They should also give you a sense of what representation at each of those stages would cost. A practitioner who says “we’ll cross that bridge when we come to it” without providing any guidance on the contingency costs is not giving you the information you need to make an informed financial commitment.

Questions About Process and Communication

“How will you keep me informed during the process?”

CP2000 matters can span several months, particularly if the IRS takes time to review a response or issues follow-up correspondence. Confirm how often and through what channels the practitioner will update you on the status of your matter. Regular proactive communication is a sign of a well-organized practice.

“Who will actually work on my matter – you, or a staff member?”

At larger firms, the practitioner you meet with during the consultation may not be the person who handles the day-to-day work. Understand who will actually review your notice, draft your response, and correspond with the IRS. If the work will be delegated to a less experienced staff member, factor that into your evaluation.

“What do you need from me to get started, and how quickly can you begin?”

A good practitioner will give you a clear list of documents they need – your CP2000 notice, your original return for the year in question, the relevant 1099s, and any documentation specific to the disputed items. They should also be able to commit to a timeline for reviewing the notice and beginning the response, given that the 60-day deadline may be partially elapsed. If the practitioner is vague about what they need or when they can start, that affects your deadline management.

“Have you had any disciplinary actions, complaints, or sanctions against your license?”

A practitioner with a clean disciplinary record should answer this question without hesitation. EA disciplinary history is maintained by the IRS Office of Professional Responsibility. CPA disciplinary history is maintained by the relevant state board. Bar disciplinary information is maintained by the state bar. Verify independently even if the answer is affirmative – practitioner self-disclosure is not always complete.

One Question That Tells You a Lot

“Based on what I’ve told you so far, what is your honest assessment of my situation – and what is the realistic range of outcomes?”

A practitioner who engages genuinely with this question – acknowledging uncertainty where it exists, identifying the strongest and weakest aspects of your position, and giving you a realistic view rather than a sales pitch – is one who will represent you honestly. A practitioner who responds with guarantees, avoidance, or an extended sales presentation before understanding your facts is telling you something important about how they operate.

Summary

Before engaging any professional for CP2000 help, ask directly about credentials and how to verify them, relevant experience with your type of discrepancy, the specific fee structure and what is included, the scope of services and how escalation would be handled, and the process for keeping you informed. The initial consultation is your opportunity to gather the information you need. A practitioner who answers these questions clearly and honestly is one you can work with effectively.
