Form 8655 authorizes a reporting agent to act for a taxpayer on employment tax filings, deposits, payments, notices, and specified information disclosures. When reviewing one for a firm, confirm four things: which lines are completed, which periods each line covers, whether the signer had authority to bind the taxpayer, and how the authorization was submitted. The authorization begins with the period entered on each line and does not reach periods before it.
Short definition. Form 8655, Reporting Agent Authorization, is the IRS form by which a taxpayer appoints a reporting agent to sign and file certain returns, make deposits and payments, receive duplicate notices, and receive certain taxpayer information, within the limits of the lines the taxpayer completes.
Scope table: what each line actually grants
| Line | What it authorizes | Period entry and effect |
|---|---|---|
| 15 | Sign and file returns | Quarterly: YYYY/MM where MM is the last month of the quarter the authorization begins; annual: YYYY the authorization begins |
| 16 | Make deposits and payments | YYYY/MM for the month the authorization begins |
| 17 | Request duplicate notices and correspondence on returns filed and deposits or payments made | Tied to the agent's filings and payments |
| 18a | Receive otherwise confidential information for the W-2 series | Effective for calendar years beginning as entered |
| 18b | Same, for the 1099 series | Effective for calendar years beginning as entered |
| 18c | Same, for Forms 3921/3922 | Effective for calendar years beginning as entered |
| 19 | Sign and file related state or local returns | Related to authority granted on line 15 and/or 16 |
Each of lines 15, 16, 18a, 18b, and 18c carries its own beginning period. Authority granted begins with the period indicated and continues indefinitely unless terminated or revoked, and no authority is granted for periods before the indicated period (Form 8655).
Two conditions, two roles: signature and IRS receipt
Signature and receipt are not the same event, and reviewers should not collapse them. The taxpayer executes the authorization by signing it; disclosure authority is stated to be effective upon the taxpayer's signature and the IRS's receipt of Form 8655 (Form 8655). A signed form sitting in a client portal is therefore not the same position as a form the IRS has received. Treat signature as the taxpayer's act of granting, and IRS receipt as a separate condition tied to when disclosure authority is stated to be effective. A file that shows only a signature date is incomplete evidence.
Who may sign
The permissible signer depends on the taxpayer's entity type. Sole proprietorship: the sole proprietor. Corporation: an officer with legal authority to bind, a person designated by the board or governing body, an officer or employee on written request by a principal officer, or another person authorized under section 6103(e). Partnership or unincorporated organization: any partner during the tax period. Single member LLC treated as a disregarded entity: the owner. Trust or estate: the fiduciary (Form 8655).
At onboarding, and whenever a known entity or authority change occurs, an optional firm check is to review appropriate signer evidence, such as formation or governing documents, before treating the signer as qualified. Form 8655 authority continues until terminated or revoked.
Ongoing employer responsibility and the written notice duty
The authorization does not relieve the taxpayer of responsibility, or liability for failing, to ensure all returns are filed timely and all federal tax deposits and payments are made timely (Form 8655). Delegation shifts who performs the act, not who bears the exposure.
A reporting agent must notify its client of that non-relieved responsibility and recommend EFTPS enrollment, and must provide the notification in writing upon entering into an agreement and at least quarterly thereafter for as long as it provides services (Form 8655). In a review, ask for the initial written notice and evidence of the quarterly notices. If the engagement file contains only the form and no notices, the administrative side of the relationship is undocumented regardless of how clean the filings look.
Reporting agents file returns electronically except as provided under Rev. Proc. 2012-32 and make deposits and payments electronically, generally through EFTPS (Form 8655). That is a baseline for the agent's own operations, not a substitute for the employer's oversight.
Relationship to Forms 2848 and 8821
Form 8655 authority does not revoke and has no effect on authority granted on Form 2848 or Form 8821, or on third-party designee checkbox authority (Form 8655). These are parallel relationships with different purposes. Form 2848 alone does not confer reporting-agent authority under Form 8655, and Form 8655 does not by itself create representation authority under Form 2848; a firm may hold both. For a side-by-side comparison, see Form 8821 vs. 2848; for sequencing both, see the submission workflow guide.
Replacement and revocation are distinct
When a different reporting agent is engaged, filing a new Form 8655 indicating the new agent terminates the prior agent's authority beginning with the period indicated on the new form. The prior agent retains previously granted disclosure authority for periods before that beginning period unless it is specifically revoked (Form 8655).
That is not the same as a retroactive revocation, which is the separate step used to strip authority so the reporting agent can no longer act or receive information for previously authorized periods. Treating replacement as if it revoked everything retroactively overstates the effect of the new form, and treating revocation as unnecessary ignores the retained disclosure authority for earlier periods.
The IRS sources describe different mechanisms for narrowing scope. The Form 8655 instructions address a decrease through a signed written request to the address under Where To File, with the preceding authorization remaining in effect except as modified, while Publication 1474 states that a new Authorization must be submitted for any increase or decrease in the scope of the reporting agent's authority (Form 8655; Publication 1474). Because these do not align, this guide does not present a single universal procedure. Before changing authorization, consult both the current instructions and Publication 1474. Increasing authority by submitting another signed Form 8655 completing lines 1-14 and any line on which authority is to be added is the mechanism the instructions address (Form 8655).
Electronic signatures
Publication 1474, Section 01.04 (Rev. 4-2026) is the only guidance for electronic signatures on Form 8655, and electronic-signature guidance for other forms may not be applied to it (Publication 1474). The Who Must Sign section of the Form 8655 instructions points to Publication 1474 section 01.03 for this topic; the current electronic-signature guidance is section 01.04, so that pointer is outdated. Do not carry over Form 8879 signature methods; the e-file signature model is a different authorization with its own rules.
Review checklist (recommended firm review workflow)
The following checklist is a recommended firm review workflow, not IRS requirements. Document-location items are internal recommendations and are separate from IRS requirements.
- Confirm each completed line maps to a documented client instruction, not an assumption about the engagement.
- Verify the period entry on every period-bearing line (15, 16, 18a-18c) and note that nothing before that period is covered.
- As an optional firm check, review appropriate signer evidence, such as the taxpayer's formation or governing documents, at onboarding and on any known entity or authority change.
- Distinguish the signature date from the date the IRS received the form in your file notes.
- Confirm the initial written notice and the at-least-quarterly written notices are on file.
- Optionally check whether the firm or representative is separately authorized under Form 2848 or Form 8821.
- When a prior agent exists, document whether the new form is a replacement or whether a separate revocation was also executed.
- Record which authority, if any, the prior agent retains for earlier periods.
- On any scope change, cite both the current instructions and Publication 1474 before acting.
- If electronic signature is used, confirm it meets Publication 1474 Section 01.04 requirements without borrowing methods from other forms.
Recommended firm controls (optional, not IRS requirements)
The following are practice recommendations, not IRS rules. Label them as internal policy when you adopt them.
- Maintain an authorization register listing each client, form type, lines completed, period start, signer, and IRS receipt date.
- Calendar the quarterly written-notice obligation at the engagement level so it survives staff turnover.
- Require a second reviewer for any authorization change that narrows or broadens scope.
- Keep replacement and revocation events as separate records with separate dates.
FAQs
Does signing Form 8655 remove the employer's liability for late deposits? No. The authorization does not relieve the taxpayer of responsibility, or liability for failing, to ensure returns are filed timely and deposits and payments are made timely.
Does Form 8655 replace power of attorney? No. It does not revoke or affect authority granted on Form 2848 or Form 8821, or third-party designee checkbox authority.
When does authority start? With the period entered on each period-bearing line. No authority is granted for periods before the indicated period.
If we bring in a new reporting agent, does the old one lose everything immediately? Not retroactively. The prior agent's authority terminates beginning with the period on the new form, but its disclosure authority for earlier periods continues unless specifically revoked.
Can we use our e-file signature process for Form 8655? Not by default. Publication 1474 Section 01.04 is the only guidance for electronic signatures on Form 8655, and methods for other forms may not be applied to it.
Next step
For each client with an active Form 8655, pull the form, the signer evidence, the IRS receipt confirmation, and the written notices into one file, then reconcile each completed line against the client's actual instructions before the next filing period.
