IRS Power of Attorney: How It Works & When You Need It?

Table of Contents

IRS Power of Attorney – Dealing with the IRS can be overwhelming—whether you’re facing an audit, collections notice, appeal, or complex tax issue. The IRS Power of Attorney (Form 2848) lets you authorize a qualified representative (like a CPA, enrolled agent, or attorney) to act on your behalf, including receiving confidential information and handling communications. This official IRS form ensures secure, limited representation without relieving you of your tax obligations.

This 2026 guide draws directly from current IRS resources (irs.gov/forms-pubs/about-form-2848 last reviewed February 19, 2026; Instructions for Form 2848 Rev. September 2021; and submission pages updated 2025) to explain when you need Form 2848, how it works, step-by-step completion, submission options, revocation, and more.

What Is IRS Form 2848?

Form 2848, titled Power of Attorney and Declaration of Representative, authorizes an eligible individual to represent you before the IRS for specific tax matters and periods. Your representative can:

Inspect and receive your confidential tax records
Sign agreements, consents, or waivers
Receive copies of IRS notices and communications (limited to two representatives)
Perform most acts you could do yourself regarding the authorized matters

Key facts (per IRS.gov):

A separate Form 2848 is required for each taxpayer (including each spouse on a joint return).
It is recorded in the IRS Centralized Authorization File (CAF) for quick verification—unless marked for “specific use only.”
Authorization does not change your mailing address (use Form 8822/8822-B for that) and does not relieve you of filing or paying taxes.
Special note: You can use Form 2848 for FBAR examinations triggered by an income tax audit.

When Do You Need an IRS Power of Attorney (Form 2848)?

Use Form 2848 whenever you want full representation (advocacy, negotiation, signing documents) rather than just information access. Common situations include:

IRS audits or examinations
Appeals or Collection Due Process hearings
Installment agreements, currently not collectible status, or Offer in Compromise
Innocent spouse relief (Form 8857)
Penalty abatement or trust fund recovery penalties
Centralized Partnership Audit Regime (BBA) matters
Requests for private letter rulings, EIN applications, or other specific non-CAF uses
When you’re ill, traveling, or unable to handle IRS matters personally
Hiring a tax professional for complex returns or disputes

Tip: If you only need someone to view/receive information (no representation), use Form 8821 instead. For very limited phone discussions on one return, a “third-party designee” checkbox on your tax return often suffices.

Who Can Serve as Your Representative on Form 2848?

Only individuals eligible to practice before the IRS. In Part II of the form, they declare their status (categories a–r):

Attorneys (in good standing)
Certified Public Accountants (CPAs)
Enrolled Agents (EAs)
Enrolled Actuaries or Enrolled Retirement Plan Agents
Family members (spouse, parent, child, sibling, grandparent, grandchild)
Full-time employees or corporate officers (for business taxpayers)
Qualifying students or recent law graduates in IRS-approved Low Income Taxpayer Clinics (LITC) or Student Tax Clinic Programs (STCP) with special Taxpayer Advocate Service authorization
Unenrolled return preparers (limited authority during examination of returns they prepared)

Foreign representatives outside the U.S. may qualify in limited cases.

Form 2848 vs. Form 8821: Quick Comparison

Feature	Form 2848 (Power of Attorney)	Form 8821 (Tax Information Authorization)
Purpose	Representation + confidential info	Confidential info only
Who can be authorized	Only eligible practitioners/individuals	Any person, firm, or organization
Can sign documents?	Yes (with limits)	No
Receives IRS notices?	Yes (up to 2)	No
Recorded on CAF?	Yes (unless specific-use)	Yes (unless specific-use)

How Form 2848 Works: The Centralized Authorization File (CAF)

Once processed, the IRS records the POA in the CAF system. IRS employees can instantly confirm your representative’s authority. Specific-use POAs (Line 4 checked) bypass CAF recording and go directly to the handling office.

Future years are limited to no more than three years ahead for CAF recording.

Step-by-Step: How to Fill Out IRS Form 2848

Download the current form (Rev. January 2021) from IRS.gov.

Part I – Completed by Taxpayer

Line 1: Your full name, address, TIN(s), daytime phone, plan number (if applicable).
Line 2: Representative’s name, address, CAF number (or “None”), PTIN, phone/fax. Check boxes to send them notices/communications and for new contact info.
Line 3: Clearly describe the matter (e.g., “Income Tax”), tax form (e.g., “1040”), and years/periods (e.g., “2019-2023”). Be specific—vague entries will be returned.
Line 4: Check only for one-time specific uses not recorded on CAF (e.g., private letter ruling, EIN application).
Line 5a: Additional acts (check as needed): access via intermediate service provider, substitute/add representatives, disclose to third parties, sign returns (must state reason per Treas. Reg. 1.6012-1(a)(5)), or other acts.
Line 5b: List any acts not authorized.
Line 6: Default revokes prior POAs for the same matters/years. Check box if you want to retain prior POAs.
Line 7: Sign and date (handwritten signature required for fax/mail). Joint filers need separate forms.

Part II – Completed by Representative

They declare eligibility, sign, and provide licensing details (bar number, CPA license, EA enrollment card, etc.).

Pro Tip: Taxpayer must sign before or within 45 days (60 days if abroad) of the representative signing.

How to Submit Form 2848? (2025–2026 Options)

The IRS offers faster digital options:

Online (fastest): Use the “Submit Forms 2848 and 8821 Online” tool (secure upload, supports electronic or handwritten signatures). Or have your tax pro submit via Tax Pro Account for you to review and e-sign in your IRS online account.
Fax or Mail: Use the state-specific addresses/fax numbers in the instructions (e.g., most eastern states → Memphis, TN; western states → Ogden, UT; international → Philadelphia).

Processing is first-in, first-out. For Line 4 specific-use POAs, send directly to the IRS office handling the matter.

How to Revoke or Update a Power of Attorney

Submit a new Form 2848 for the same matters/years → automatically revokes the prior one.
Specific revocation: Write “REVOKE” across a copy of the old form, sign/date it, and fax/mail to the same location.
Representative can withdraw by sending a signed statement.

Common Mistakes to Avoid

Using vague language on Line 3 (“all years” or “all taxes” will be rejected).
Forgetting separate forms for married filing jointly.
Attempting digital signatures on fax/mail submissions.
Authorizing someone not eligible to practice before the IRS.
Forgetting to attach required documentation (e.g., TAS letter for LITC students).

Frequently Asked Questions (FAQs)

Can I use a general durable power of attorney instead of Form 2848?
Generally no for competent taxpayers. In cases of incapacity, a properly drafted durable POA may allow your attorney-in-fact to execute Form 2848 on your behalf—consult an estate/tax attorney and see IRS guidance on fiduciaries (Form 56).

How long does processing take?
Varies; online submissions are typically faster, but the IRS processes in the order received.

Does Form 2848 cover future tax years?
Up to three years ahead for CAF recording.

Is there a fee?
No IRS fee to file Form 2848.

Can family members represent me?
Yes—spouse, parent, child, etc., qualify without needing professional credentials.

Always use the latest form and instructions from IRS.gov.
Keep copies for your records.
Communicate clearly with your representative about the scope of authority.
