Tax preparers regularly need to interact with the IRS on behalf of clients: pulling transcripts, resolving notices, responding to inquiries, and in some cases representing clients in examinations or collection matters. Two IRS authorization forms govern that access. Form 2848 (Power of Attorney) lets you act for the client before the IRS. Form 8821 (Tax Information Authorization) lets you receive IRS information on the client's behalf without acting for them. Knowing which form to use, and when each is legally sufficient, is a practical compliance skill every preparer needs.
The information in this guide reflects IRS rules as of 2026. Because IRS procedures and form requirements are subject to change, verify current requirements at IRS.gov before relying on any specific procedural detail. This guide is informational and does not constitute legal or professional advice.
Form 2848 (Power of Attorney): Authorize Acting on the Taxpayer's Behalf
Form 2848 is the IRS Power of Attorney form. When a taxpayer signs it and names you as their representative, you are authorized to act on their behalf before the IRS -- not just receive information, but take action. That distinction is the core of what separates Form 2848 from Form 8821.
What Form 2848 authorizes
A valid Form 2848 authorizes you to represent the taxpayer in IRS examinations and audits, respond to IRS notices and correspondence on the taxpayer's behalf, sign closing agreements and consents to assessments, negotiate installment agreements and other collection resolutions, represent the taxpayer before IRS Appeals, and receive IRS notices and communications that would otherwise go to the taxpayer. The scope of authority on the form is defined by the tax matters and years you list; you are authorized only for what the form specifies.
Who is eligible to be named as a representative
The IRS restricts who may serve as a representative under Form 2848. As of 2026 (verify at IRS.gov), eligible practitioners include:
- Enrolled Agents (EAs): federally authorized practitioners with unlimited representation rights before the IRS. See the Enrolled Agent credential guide for qualification requirements.
- Certified Public Accountants (CPAs): licensed by their state board; eligible for full representation rights before the IRS.
- Attorneys: licensed by their state bar; eligible for full representation rights before the IRS.
- Other IRS-eligible practitioners: including enrolled actuaries, enrolled retirement plan agents, and unenrolled return preparers with limited rights under certain IRS programs (see the AFSP section below).
Unenrolled preparers who do not hold a recognized credential and have not completed the Annual Filing Season Program (AFSP) do not have representation rights and cannot be named as a representative on Form 2848 for most IRS contacts. If a client's matter requires representation and you are not an eligible practitioner, advise the client to retain someone with the appropriate credential.
When to use Form 2848
Use Form 2848 when the client's situation requires you to act, not merely receive information. Common scenarios:
- The client received an audit notice and needs you to represent them in the examination
- A CP notice requires a substantive response or a signed agreement
- You are negotiating an installment agreement or offer in compromise
- The matter is heading toward or has reached IRS Appeals
- You need to sign IRS closing agreements on the taxpayer's behalf
CAF number and registration
When you submit a Form 2848, the IRS processes it through the Centralized Authorization File (CAF) system and assigns a CAF number to the representative if one has not already been issued. Your CAF number ties your authorization to the client's account records in the IRS system. Once your authorization is on the CAF, IRS personnel handling the applicable matters can verify your authority to act. You will need an active PTIN and, for most representation purposes, an EFIN on file as part of your IRS credentials. Verify current CAF registration procedures at IRS.gov (as of 2026).

Form 8821 (Tax Information Authorization): Authorize Receiving IRS Information
Form 8821 is the Tax Information Authorization form. It does one thing: it authorizes the IRS to disclose tax information to a designee you name. It does not authorize you to act on the taxpayer's behalf in any way. That narrower scope is both its limitation and its practical advantage for certain preparer workflows.
What Form 8821 authorizes
Form 8821 authorizes the IRS to disclose the taxpayer's return information to the named designee. That includes wage and income transcripts, return transcripts, account transcripts, record of account, tax compliance verification, and IRS notices. The designee receives information; that is the full extent of the authorization. The designee cannot sign documents, make agreements, argue a position with the IRS, or represent the taxpayer in any examination, collection matter, or dispute.
No credential requirement for the designee
Unlike Form 2848, Form 8821 carries no credential requirement for the designee. Any individual or entity the taxpayer authorizes can be named: the preparer who handled their return, a bookkeeper managing their accounts, an office administrator, or a support staff member. This flexibility makes Form 8821 the practical choice in situations where transcript access is the only need, or where the person pulling transcripts is not a credentialed representative.
When to use Form 8821
Use Form 8821 when your purpose is information access, not representation. Common preparer scenarios:
- Pulling wage and income transcripts to verify income figures before preparing a return
- Obtaining account transcripts to check the payment history, penalties, or balance due for a client
- Routing IRS notices to your office so you are aware of any IRS activity on the account
- Giving a bookkeeper or support staff member the access they need to retrieve transcripts without granting representation authority
- Monitoring a client's account without being retained for active representation
What Form 8821 cannot do
Form 8821 does not authorize the designee to sign any IRS document, make any agreement on the taxpayer's behalf, advocate a position in an examination, respond substantively to an IRS notice, or represent the taxpayer before any IRS office. If your client receives an audit notice and needs you to respond, Form 8821 is not sufficient; a valid Form 2848 (and eligible practitioner status) is required. The Section 7216 rules on client data handling apply independently of your CAF authorization, so maintain appropriate data security practices for any IRS records you receive.
Side-by-Side Comparison: Form 2848 vs Form 8821
The table below summarizes the key differences as of 2026. Verify current IRS requirements at IRS.gov before relying on any specific rule.

Decision Guide: Which Form to Use
The decision between Form 2848 and Form 8821 comes down to one question: does the client need someone to act on their behalf, or only to receive information?
Use Form 2848 when representation is required
If the client needs someone to respond to the IRS on their behalf, sign agreements, argue a position in an examination, or handle an appeal, Form 2848 is the correct form. The scenarios where Form 2848 is required include:
- Audit representation: the client has been notified of an IRS examination and needs a practitioner to appear, submit documents, and advocate their position
- Notice response: a CP notice requires a substantive reply, an abatement request, or a signed consent to assessment
- Collection matters: negotiating a payment plan, currently-not-collectible status, or an offer in compromise
- Appeals: the client is contesting an IRS determination and needs representation before the Office of Appeals
Remember: you can only serve as a representative on Form 2848 if you are an eligible practitioner. If you are not, do not submit Form 2848 as the named representative; advise the client to retain someone with the appropriate credential and refer them accordingly.
Use Form 8821 when transcript access is the only need
If you need to pull transcripts, verify account history, or route IRS notices to your office without any active representation role, Form 8821 covers that need -- and you do not have to be a credentialed practitioner to be named as a designee. Common preparer-side uses:
- Pulling wage and income transcripts to verify W-2 and 1099 data before filing
- Retrieving account transcripts to assess prior-year balances, estimated tax payments, or penalty history
- Monitoring an account for IRS notices as part of an ongoing client relationship
- Authorizing a bookkeeper or office staff member to retrieve IRS records without granting representation authority
Filing both forms for the same client
You can file both Form 2848 and Form 8821 for the same client. The forms are not mutually exclusive; they serve different functions that can coexist. In a typical audit engagement, a credentialed preparer might file Form 2848 to authorize representation in the examination and Form 8821 to ensure all IRS transcript requests and notices are also routed to their office. The CAF system records each separately. Verify current IRS procedures for dual authorization at IRS.gov (as of 2026).
AFSP and Limited Representation Rights
For non-credentialed preparers, the Annual Filing Season Program (AFSP) is the IRS pathway to limited representation rights. Understanding exactly what those rights cover is important before you complete and submit a Form 2848.
What AFSP representation rights cover
Preparers who complete the required AFSP continuing education hours and sign the Circular 230 consent receive limited representation rights under Treasury Circular 230 (as of 2026; verify at IRS.gov). Those rights authorize the AFSP participant to represent clients before:
- IRS revenue agents
- Customer service representatives
- Similar IRS personnel
- The Taxpayer Advocate Service
A critical condition: AFSP representation rights apply ONLY on returns the AFSP participant personally prepared and signed. You cannot use your AFSP status to represent a client on a return you did not prepare. When those conditions are met, you use Form 2848 for those limited IRS contacts.
What AFSP representation rights do not cover
AFSP does not grant representation rights before IRS Appeals Officers or the U.S. Tax Court. If a client's matter progresses to either of those forums, an Enrolled Agent, CPA, or attorney is required for continued representation. At that point, advise the client accordingly rather than attempting to extend your AFSP-based authority beyond its defined scope.
Do not represent to clients that AFSP confers the same authority as an enrolled agent credential or any other full-scope practitioner designation. AFSP is a structured annual CE program with IRS recognition; it is not a license or a credential in the same sense as an EA, CPA, or attorney.
AFSP and Form 8821 for non-credentialed preparers
Non-credentialed preparers who have not yet completed AFSP, or who are in the process of pursuing their credential, can still use Form 8821 freely. Because Form 8821 requires no credential from the designee, any preparer can be authorized to pull transcripts and receive IRS notices regardless of their credential status. When the work requires only information access and not representation, Form 8821 is the right tool regardless of where you stand in the credentialing process. If you are working toward your EA credential, see the Enrolled Agent career guide for full details on qualification requirements.
Practical Workflow for Tax Preparers
The following workflow guidance applies the Form 2848 vs Form 8821 distinction to the situations preparers encounter most often.
Return preparation: use Form 8821 for transcript pull
When preparing a return and you need to verify income figures -- W-2 data, 1099s, or Social Security income -- pull IRS wage and income transcripts using Form 8821. No credential is required for this purpose. Have the client sign Form 8821 at the start of your engagement so transcript access is available when you need it. This is particularly useful for clients with complex income situations, prior-year discrepancies, or missing documents. Keep the signed Form 8821 in the client file.
IRS notice received: assess whether representation is required
When a client receives an IRS notice, the first question is whether responding requires you to act on their behalf or only to gather information. If the notice is informational (an account balance summary, a refund notice, a transcript request), Form 8821 access may be sufficient to gather what you need. If the notice requires a substantive response, a signed agreement, or audit representation, Form 2848 is required -- and you must be an eligible practitioner to sign it. If you are not, advise the client to retain someone with the appropriate credential: an Enrolled Agent, CPA, or attorney.
Audit engagement: upgrade to Form 2848 if eligible
If you are an eligible practitioner and the client needs audit representation, complete and submit Form 2848 to cover that engagement. Specify the exact tax years and tax matters you are authorized to handle. If you filed Form 8821 earlier in the engagement, you can maintain that alongside the Form 2848; the two authorizations coexist and cover different functions. If you are not an eligible practitioner, do not attempt to represent the client under Form 2848; refer them to a credentialed representative and, if appropriate, remain on the engagement in an information-access role under Form 8821.
Storing authorizations: keep copies, define scope clearly
Retain signed copies of both Form 2848 and Form 8821 in each client's file. The scope of the authorization is defined by what is listed on the form: the tax type, the tax years, and the specific matters covered. If the client's situation changes (new tax years, new tax matters), a new or updated authorization form may be needed. As a best practice, review client authorization forms annually at the start of each filing season and update them to reflect any changes in scope or the client's current situation. This is part of maintaining proper client records and supports your data security obligations. Consult your Certifying Acceptance Agent resources if your practice handles ITIN-related authorization matters, as additional considerations may apply.
Electronic submission: verify current IRS e-signature guidance
The IRS has accepted electronic signatures on both Form 2848 and Form 8821 under certain circumstances. The specific rules and approved methods for e-signatures on these forms are subject to change. Before submitting either form electronically or with an electronic signature, verify current IRS e-signature guidance at IRS.gov (as of 2026). Using an electronic signature method that does not meet current IRS requirements can result in a rejected or unprocessed authorization. The IRS also has a Tax Pro Account portal that allows certain authorizations to be submitted and managed online; verify availability and current procedures at IRS.gov.
Frequently Asked Questions
What is the difference between Form 2848 and Form 8821?
Form 2848 (Power of Attorney) authorizes a representative to act on the taxpayer's behalf before the IRS: signing documents, making agreements, arguing positions, and representing the taxpayer in audits, collection matters, and appeals. The representative must be an eligible practitioner (enrolled agent, CPA, attorney, or other IRS-eligible representative). Form 8821 (Tax Information Authorization) authorizes a designee only to receive IRS tax information: transcripts, notices, and account information. A Form 8821 designee cannot act on the taxpayer's behalf, sign documents, or represent the taxpayer in any dispute. The designee can be anyone; no credential is required. Both forms are processed through the IRS Centralized Authorization File (CAF) system. Verify current IRS requirements at IRS.gov, as of 2026.
Can an unenrolled tax preparer use Form 2848?
Only in limited circumstances. Unenrolled preparers who have completed the IRS Annual Filing Season Program and signed the Circular 230 consent receive limited representation rights. Those AFSP participants may use Form 2848 to represent clients before revenue agents, customer service representatives, and similar IRS personnel, but only on returns they personally prepared and signed. Unenrolled preparers who have not completed AFSP do not have representation rights before the IRS and cannot use Form 2848 for representation purposes. For full representation rights across all IRS matters, Enrolled Agent, CPA, or attorney status is required. Verify current AFSP and representation rules at IRS.gov, as of 2026.
Do I need Form 2848 or Form 8821 to pull IRS transcripts?
Form 8821 is the appropriate form for pulling transcripts when you are not representing the client in a dispute. Form 8821 authorizes the IRS to disclose tax information (including wage and income transcripts, account transcripts, and return transcripts) to the designee you name. You do not need to be a credentialed practitioner to be named as a Form 8821 designee. If you are also representing the client before the IRS (in an audit, collection matter, or notice response), Form 2848 is required for that representation purpose, and you may file both forms. Once authorization is on file, see our guide to IRS Transcripts for Tax Practitioners for the step-by-step workflow of pulling each transcript type through TDS. Verify current IRS transcript access procedures at IRS.gov, as of 2026.
How long does a CAF authorization last?
Both Form 2848 and Form 8821 remain in effect for the tax years and tax periods specified on the form unless you or the taxpayer revoke the authorization earlier. You can specify an expiration date on the form; if none is specified, the IRS CAF authorization generally remains on file for the scope defined on the form. A new Form 2848 for the same taxpayer and tax matters generally supersedes a prior Form 2848 (unless you indicate otherwise on the new form). Verify current IRS CAF duration and revocation procedures at IRS.gov, as of 2026.
Can I file both Form 2848 and Form 8821 for the same client?
Yes. The two forms serve distinct functions and can coexist for the same client. Form 2848 covers your authority to act on the client's behalf before the IRS (representation). Form 8821 covers your authority to receive IRS information about the client (transcript and notice delivery). Filing both is a common and practical approach: use Form 2848 for audit representation or a notice response that requires you to act, and use Form 8821 to ensure transcripts and IRS notices are routed to you as well. Verify current IRS procedures for dual authorization at IRS.gov, as of 2026.
