What Form 2848 does
Form 2848, Power of Attorney and Declaration of Representative, grants a named representative the authority to act on the taxpayer's behalf before the IRS. When the form is on file, the representative can:
- Call, write, and negotiate with the IRS on the taxpayer's behalf
- Receive and inspect confidential tax information
- Receive (but not endorse or cash) refund checks, if explicitly authorized
- Sign a consent to extend the assessment statute, closing agreements, and other documents named on line 5a
- Receive copies of notices and correspondence the IRS sends to the taxpayer
This is a full-authority form. If you only need transcript access or information, see Form 8821 instead — less friction and fewer rejection traps.

Line-by-line walkthrough
What follows references the current published revision (Rev. Jan 2021). Box numbers map directly to the PDF.
Line 1Taxpayer information
Name, address, and taxpayer identification number. For a business, use the entity name and EIN; do not put the owner's SSN.
- Spouses need separate 2848s even for jointly filed returns — one form per taxpayer, always.
- For a disregarded single-member LLC, the IRS treats the owner as the taxpayer for income tax matters — use the owner's SSN/EIN per the client's filing pattern.
- If the address on file with the IRS differs from the address you enter, the form may still process, but CP notices will go to the IRS's address of record, not this one.
Line 2Representative(s)
Up to four reps fit on one 2848. For each rep:
- CAF number — the Centralized Authorization File number the IRS assigned when your first authorization was processed. New reps write "NONE" and the IRS assigns one on first filing.
- PTIN — required if the rep is signing returns for compensation; include even if technically optional.
- Bar / license / enrollment number — state bar number for attorneys, license number for CPAs, enrollment number for EAs.
- Check the box if you want the IRS to send notices and communications to this rep.
- "Check here if new address/phone/fax" — check this if your CAF record on file has stale contact info. Failing to do this leaves old CAF info intact.
Line 3Acts authorized — the rejection hotspot
Three columns: Description of Matter, Tax Form Number, Year(s) or Period(s). This is where most rejections happen.
2019, 2020, 2021, 2022, 2023) or use a bounded range (2019-2024) that doesn't extend more than three years into the future.Year/period rules
- You may list prospective years up to three years after the year the form is signed. A 2848 signed in 2026 can cover through 2029.
- For employment and excise taxes, use quarterly periods:
1st Qtr 2023 – 4th Qtr 2024. - For civil penalties with no tax form number, put "Civil Penalty" in the form column and list the period the penalty relates to.
Tax form number examples
- Individual income tax →
1040 - C-corp →
1120; S-corp →1120S; partnership →1065 - Employment tax →
941,940,944 - Trust Fund Recovery Penalty →
Civil Penalty(form column), plus the underlying 941 periods
Line 4Specific use not recorded on CAF
Check this box only for one-off matters the IRS will not record on the CAF (examples: private letter ruling requests, certain employee plan actions, disclosure authorizations for a third party like a lender). If you check this box for a normal engagement you will not appear on CAF, and you won't be able to pull transcripts under your CAF — leave it unchecked for standard representation.
Line 5a / 5bAdditional acts authorized / specifically not authorized
5a — Additional acts. Check any that apply:
- Authorize disclosure to third parties
- Substitute or add representative(s)
- Sign a return (must also attach a statement explaining which return and why under 26 CFR 1.6012-1(a)(5))
- Other acts (describe — e.g., "authority to receive but not endorse or cash refund checks")
5b — Specific acts NOT authorized. Use this to carve out authority you don't want the rep to have. Common carve-outs: endorsing refund checks, signing closing agreements, consenting to disclosure of return info.
Line 6Retention or revocation of prior power(s) of attorney
By default, filing a new 2848 revokes all prior POAs for the same matters and periods. If you want to keep prior representatives on file (e.g., you're adding a second rep to an existing engagement), check the box and attach a copy of the prior 2848 you want to retain.
Line 7Taxpayer signature
Signed and dated by the taxpayer. Key rules:
- Joint returns: both spouses must sign — but again, on separate 2848s, one per spouse.
- Entity: signed by a corporate officer, partner, member-manager, fiduciary, or other person authorized to act. Print the title.
- 45-day rule: the IRS may reject a 2848 if it reaches them more than 45 days after the taxpayer's signature date on a mailed/faxed submission (online submissions are typically processed much faster and this is less of a concern). Get it in fast.
Part IIDeclaration of representative
Each rep signs Part II with:
- Designation letter (a through r from the list above)
- Licensing jurisdiction (state bar, state of CPA licensure, etc.) — EAs use "EA"
- Bar / license / enrollment number
- Signature and date
Submission methods
| Method | Typical processing | Notes |
|---|---|---|
| Tax Pro Account (IRS.gov) | Often same-day to a few business days | Requires the client to sign electronically in their own IRS Online Account. Fastest path when both parties are online. |
| Submit Forms 2848 and 8821 Online | ~5 business days to CAF | You upload a signed PDF. Taxpayer signature can be handwritten or electronic (meeting IRS e-signature guidance). |
| Fax to the CAF unit | Weeks — backlog-dependent | Fax numbers vary by region; see current Form 2848 instructions. Slowest and most failure-prone path. |
| Mail to the CAF unit | Weeks to months | Use only when nothing else is available. Mail submissions were severely backlogged after 2020 and remain the slowest route. |
The current CAF unit mailing addresses and fax numbers are on the IRS site under Where to File Your Taxes for Form 2848. Don't trust cached copies — they change.
Common rejection reasons and fixes
Unsigned by one spouse on joint-return matters
Joint returns require separate 2848s for each spouse. Filing one form with two signatures covering both spouses is rejected. Fix: file two forms, one per spouse.
Outdated form revision
The IRS only accepts the current published revision. Fix: download fresh from irs.gov and re-sign.
Overly broad year range on line 3
"All years," "all taxes," or ranges extending more than three years in the future will be rejected. Fix: enumerate specific years within the allowable window.
Missing CAF number / PTIN / designation
If the rep has no CAF, write "NONE" — don't leave blank. Part II must have a designation letter and matching jurisdiction. Fix: fill every field, even if with "NONE" or "N/A" where appropriate.
Signature more than 45 days old (mail/fax)
A signature that's stale by the time the form reaches the CAF unit can be rejected. Fix: have the taxpayer re-sign and re-date, or switch to online submission where timing is more forgiving.
Wrong CAF unit address/fax
The IRS routes by taxpayer state. Submitting to the wrong unit adds weeks. Fix: check the current routing chart in the Form 2848 instructions before faxing or mailing.
CAF provisioning after filing
Your CAF (Centralized Authorization File) number is a nine-digit number the IRS assigns the first time you're recorded as a representative. It's yours for life and travels with you across firms and clients.
First-time reps
Write "NONE" in the CAF field on your first 2848. When the IRS processes it, they'll assign a CAF number. You'll find it on CAF77 notices, or by calling the Practitioner Priority Service (PPS) with your identity info.
Sync delay
Even after a successful submission, the CAF database takes time to propagate. Typical sync times:
- Tax Pro Account submissions: often visible within 1–3 business days
- Online Submit Forms 2848/8821: typically ~5 business days
- Fax/mail: anywhere from several weeks to months
Until CAF has your authorization, TDS (Transcript Delivery System) will refuse transcript pulls with "No current authorization." This is the most common cause of "why isn't TRH pulling this client's transcripts?" — the 2848 simply hasn't hit CAF yet.
Revoking or replacing a POA
Three ways to remove authority:
- File a new 2848 without checking the line 6 retention box. This automatically revokes all prior POAs for the same matters and periods.
- File a written revocation. Send a copy of the prior 2848 marked "REVOKE" across the top, signed and dated, to the CAF unit. If you don't have the original, send a signed statement naming the representative and matters being revoked.
- Rep withdrawal. The representative can withdraw by sending a written statement to the CAF unit, signed and dated, identifying the client, matter, and periods.
Special situations
Deceased taxpayer
The executor or administrator signs on behalf of the estate. Normally attach Form 56, Notice Concerning Fiduciary Relationship, either before or with the 2848. Letters testamentary or court appointment documentation may be required.
Minor children
A parent or legal guardian signs. Include the minor's name on line 1 (name and SSN) and the signing parent's name/relationship on line 7. Where "taxpayer" signatures are required, sign as "[Parent name], parent of [minor name]."
Businesses
- Corporation: an officer authorized to bind the entity (president, treasurer, etc.)
- LLC taxed as partnership or corporation: a member-manager or officer
- LLC disregarded: the single owner
- Partnership: any general partner or LLC manager
- Trust / estate: trustee or fiduciary
Foreign taxpayers
The same form applies. The taxpayer's foreign address goes on line 1. The representative must still be eligible under the designation list — foreign counsel admitted only to a foreign bar do not qualify as "attorneys" for 2848 purposes unless also admitted to a U.S. jurisdiction.
How TRH uses your 2848
TRH is not a submission service for Form 2848. We don't transmit your POA to the IRS; that's on you, through Tax Pro Account, the online submission portal, or fax/mail.
Once your authorization is on CAF, TRH pulls transcripts under your CAF number through IRS TDS. The typical flow:
- You generate a 2848 in TRH's Bulk POA module (auto-populated from client data)
- You submit through Tax Pro Account or the online submission portal
- CAF posts the authorization (1–5 business days typical for online submissions)
- TRH pulls transcripts automatically under your CAF — no separate step in the app
If TRH reports "No current authorization" for a client you believe is on CAF, the most likely causes are: CAF hasn't synced yet, the line 3 tax form/period isn't what you're trying to pull, or a prior POA silently revoked yours. See Form 8821 for the information-only alternative often used for transcript-only relationships.
