What Is IRS Form 2848 for a CP2000?

When someone other than the taxpayer needs to communicate with the IRS about a CP2000 notice, Form 2848 is the document that makes that possible.

IRS Form 2848, Power of Attorney and Declaration of Representative, gives a designated individual the legal authority to act on a taxpayer’s behalf in dealings with the IRS. In the context of a CP2000 notice, this typically means allowing a tax professional – such as a CPA, enrolled agent, or tax attorney – to review the notice, prepare a response, and communicate directly with the IRS about the proposed changes. Understanding what Form 2848 does and how it fits into the CP2000 process can help taxpayers decide whether to handle the matter themselves or bring in a representative.

What Form 2848 Actually Does

Form 2848 is not simply a contact authorization. It grants a specific individual the authority to represent a taxpayer before the IRS, which includes the ability to receive and inspect confidential tax information, submit responses on the taxpayer’s behalf, and in some cases, execute agreements with the IRS.

This is different from Form 8821, which only authorizes someone to receive and inspect tax information – without the ability to act or speak on the taxpayer’s behalf. If someone needs to respond to a CP2000 notice on behalf of another person, Form 2848 is generally the appropriate document because it allows for active representation, not just access to records.

The authority granted through Form 2848 applies only to the tax matters and years listed on the form. A representative authorized for one tax year cannot automatically act on matters from other years unless those are also included on the form.

Who Can Be Listed as a Representative

The IRS limits who can serve as an authorized representative under Form 2848. Eligible individuals include:

• Attorneys
• Certified Public Accountants (CPAs)
• Enrolled agents
• Enrolled actuaries
• Enrolled retirement plan agents
• Unenrolled return preparers with limited representation rights
• Certain other individuals permitted under IRS rules

Family members, friends, or other individuals who do not fall into a permitted category generally cannot be listed as representatives under Form 2848. The representative must also sign the declaration section of the form, confirming they are eligible and authorized to practice before the IRS.

How Form 2848 Fits Into a CP2000 Response

A CP2000 notice is not a bill or a formal audit. It is a proposed change based on income or payment information the IRS received from third parties – such as employers, banks, or investment platforms – that does not appear to match the tax return on file. The taxpayer has the option to agree, disagree, or partially disagree with the proposed adjustment.

When a tax professional is handling the response, they will typically need to file Form 2848 so the IRS recognizes their authority to act. Without it, the IRS will generally only communicate directly with the taxpayer, and the representative will not be able to call, write, or negotiate on their behalf.

Once a valid Form 2848 is on file, the designated representative can receive IRS correspondence about the matter, submit a written response to the CP2000, provide supporting documentation, and request additional time to respond if needed. The IRS will also typically send copies of any follow-up notices to the representative.

Completing Form 2848 for a CP2000 Matter

The form has several sections that must be completed carefully. In Part I, the taxpayer provides their name, address, and tax identification number. The representative’s information is also listed here, along with the specific acts they are authorized to perform.

The tax matters section asks for the type of tax involved, the tax form number, and the specific years or periods covered. For a CP2000 matter, this would typically be Form 1040 for the individual income tax year in question. Getting the tax year correct is important as a Form 2848 that lists the wrong year will not be recognized as valid for the matter at hand.

Part II is completed by the representative, who must sign and provide their designation, licensing information, and jurisdiction or enrollment details. Both the taxpayer and the representative must sign the completed form before it is submitted.

Where to Submit the Form

When Form 2848 is being filed in connection with a CP2000 notice, it can generally be submitted together with the written response to the notice. The response package is sent to the address printed on the CP2000 itself, which varies depending on which IRS campus is processing the case.

Alternatively, the form can be submitted through the IRS’s online Tax Pro Account portal or by fax to the IRS’s Centralized Authorization File (CAF) unit, depending on the circumstances. If the response deadline is approaching, fax submission is often faster than mailing.

Processing a Form 2848 can take several weeks when submitted through standard mail channels. Submitting by fax or including it directly with the CP2000 response can help reduce delays in the IRS recognizing the authorization.

Revoking or Updating the Authorization

A Form 2848 authorization does not last indefinitely. The taxpayer can revoke it at any time by submitting a written statement to the IRS, or by filing a new Form 2848 that supersedes the previous one. The representative can also withdraw by notifying both the IRS and the taxpayer in writing.

If the CP2000 matter is resolved and no further representation is needed, some taxpayers choose to formally revoke the authorization. This involves sending written notice to the IRS office that has the original form on file.

When to Consider Using Form 2848

Not every CP2000 response requires professional representation. Some notices involve straightforward discrepancies that taxpayers can address on their own with supporting documents.

When the proposed adjustment involves a significant dollar amount, complex income reporting issues, or when a taxpayer simply prefers not to manage IRS correspondence independently, working with a qualified representative and filing Form 2848 can bring structure and clarity to the process. In those situations, having a properly authorized representative on file means the IRS has a single point of contact, and the taxpayer does not have to handle every piece of correspondence personally.
