Access, Representation, Then Submission: A Small-Office Authorization Workflow

Before a small tax or accounting office touches a single form, it needs to answer one question: does the third party need to see the client's tax information, or does the third party need to speak and act on the client's behalf before the IRS? Those are two different kinds of authority, and the IRS treats them separately. Only after that question is settled does it make sense to think about which submission channel to use. This article treats access-versus-representation and channel selection as two separate steps, in that order, because the IRS itself draws that distinction — not because any source confirms that combining them is a common source of error.

This workflow walks through that sequence — access, representation, then submission — for a generic small office handling generic client requests. It does not tell any specific office or taxpayer which authority they need; it lays out the distinctions the IRS itself draws, so the office can apply its own judgment or bring the question to a qualified professional.

Information access: Form 8821

When a third party — a bookkeeper, a family member, a software provider — only needs to inspect or receive a client's confidential tax information for specified tax types and periods, the IRS route is Form 8821. This form authorizes information access only. It does not authorize the third party to represent the taxpayer before the IRS in any capacity. An office that needs representation authority and files only Form 8821 has not obtained it; representation acts and eligibility are governed by Form 2848 and its current instructions, not by this article.

Representation: Form 2848

When the office (or another third party) needs to represent the taxpayer before the IRS, the IRS directs taxpayers to Form 2848. This article does not walk through who is eligible to serve as a representative, which acts a representative can perform, or which tax matters and periods a given Form 2848 can cover — those rules live in the current Form 2848 instructions, and an office should confirm them there or with a qualified professional before relying on this workflow.

Choosing a submission channel

Once the office has decided which authorization route applies — and checked the current form instructions if more than one authorization may be involved — the next decision is how to submit. The IRS describes three routes, and they are not interchangeable.

A Tax Pro Account lets a user request tax information authorization (TIA) for individual taxpayers, within the matters and periods the IRS lists as supported for that account. Requesting power of attorney (POA) authority through the same account additionally requires the IRS-listed authority to practice before the IRS — POA eligibility through Tax Pro Account is not open to every requester the way TIA requests are.

Processing speed also differs by route. Tax Pro Account offers real-time processing only for the specific requests it supports; secure upload and fax or mail submissions are processed first-in, first-out, and an office should expect they may take longer.

Signature requirements differ too. Secure upload accepts individual or business taxpayer forms with either an electronic or a handwritten signature. Fax and mail submissions require a handwritten, wet-ink signature.

Coverage differs as well. Creating a new request through Tax Pro Account is limited to individual taxpayers and to the matters and periods the IRS lists as supported there. The form-based routes — secure upload, fax, and mail — support a broader range of taxpayer types and matters. (This individual-taxpayer limit applies only to creating new Tax Pro Account requests; it does not apply to viewing or withdrawing existing authorizations, covered below.)

For anything that falls outside these general distinctions, the office should check the current form instructions and the IRS route overview directly.

Submission confirmation is not processing or acceptance

A confirmation email after an online upload confirms receipt or successful submission — nothing more. The IRS does not use that email to confirm that processing is complete, that the request has been approved, or that an authorization is active, so an office should not treat "submitted" as the same status as "received," "processed," "approved," or "active." This article does not offer a processing-time estimate for any route, because none is available from the source it relies on.

Pre-submission office check

Before an office sends any authorization request, a short internal check can catch avoidable errors:

• Confirm the form matches the authority actually needed — information access, representation, or both. This checklist is a reminder, not a substitute for that judgment.
• Confirm the form carries the signatures its own instructions require.
• For online upload, submit one form per request, with any attachments consolidated into a single file alongside the form. The IRS states a file-size limit for these uploads; confirm the current figure on the IRS site rather than relying on a number repeated secondhand.
• Confirm the taxpayer type and the tax matter or period fit the coverage the chosen route actually supports.
• Before submitting a new Tax Pro Account request, check for authorizations already on file. A new Tax Pro Account request covering the same authorization type, matters, and periods revokes the prior authorization automatically. Secure upload, fax, and mail submissions can also retain or revoke a prior authorization covering the same matters and periods, depending on how the request is completed; retaining one requires following the current Form 2848 or Form 8821 instructions, including the retention/revocation selection the IRS describes and attaching the prior authorization as those instructions specify.

Revoking and withdrawing authority

Three related actions are easy to blur together, but they involve different people and different mechanics.

A taxpayer who wants to revoke an authorization writes "REVOKE" across the top of the form, then signs and dates it, following the applicable Form 2848 or Form 8821 instructions.

A representative who wants to withdraw from a Form 2848 authorization writes "WITHDRAW" across the top of the first page of the form and signs and dates below that annotation.

Tax Pro Account offers a third mechanic. Once an individual or business CAF number is properly linked to the account — by the person assigned an individual CAF number, or by a Designated Official or Sole Proprietor for a business CAF number — the account can display the active individual and business authorizations recorded on that CAF number, whether they were originally submitted by form or through Tax Pro Account, and allow real-time withdrawal from any of them. This CAF-linked withdrawal view is not limited to the individual-taxpayer, listed-matter scope that governs creating new Tax Pro Account requests.

A note on narrower alternatives, and where this workflow stops

Two narrower mechanisms sometimes get confused with Form 8821 and Form 2848. A third-party designee named on a filed return generally has authority tied to that return's processing, typically for about a year from its due date. Oral authorization given during a call is generally limited to that conversation. Neither replaces the ongoing authority that Form 8821 or Form 2848 provides.

Whenever the type of authority needed, who can sign, or which tax matters and periods apply is unclear, the office should turn to the current IRS forms and instructions and to an appropriately qualified tax or legal professional. This article is a workflow overview, not tax or legal advice, and it does not determine any specific authorization outcome.
