The IRS spent late August laying out, in plain terms, the different ways a taxpayer can hand someone else legal standing to deal with a federal tax matter. For a family helping an aging parent manage Social Security paperwork, income-linked Medicare premiums, or a stack of unopened IRS notices, the distinction between two commonly confused documents — Form 2848 and Form 8821 — determines whether the person helping can actually speak for the parent or only look at the file.
Both forms route through the same agency and, increasingly, the same online systems, but they grant very different powers. Confusing the two can leave a caregiver locked out of a phone call with the IRS at the exact moment help is needed, or, in the other direction, hand over more legal authority than the family situation actually calls for.
Form 2848 Hands Someone Full Representative Authority
According to IRS Tax Tip 2026-66, published Aug. 27, 2026, a Power of Attorney filed on Form 2848 lets a representative act on a taxpayer’s behalf when resolving matters with the IRS. The representative can represent, advocate, negotiate and sign on the taxpayer’s behalf; argue the facts and the application of law; receive tax information for the specific matters and years listed on the form; and receive copies of IRS notices and communications.
The catch, spelled out in the same guidance, is that a Form 2848 representative “must be an individual authorized to practice before the IRS.” The traditional categories are attorneys, certified public accountants and enrolled agents, along with a handful of narrower categories such as enrolled actuaries. That requirement is a large part of why Form 2848 is typically the document a family files when hiring a CPA or enrolled agent to sort out a parent’s return, an audit or a collection notice — rather than simply the form an adult child fills out to keep track of things.

Form 8821 Opens the File Without Handing Over Any Authority to Act
Form 8821, Tax Information Authorization, works differently. It authorizes “any individual, corporation, firm, organization, or partnership” to inspect and receive a taxpayer’s confidential tax information, verbally or in writing, for the tax type and years listed — with no requirement that the designee be a credentialed tax professional. That makes it the more realistic document for an adult child who mainly needs visibility into a parent’s account: whether a notice went out, what a balance is, or whether a return was received.
What Form 8821 does not do matters just as much. It carries no representation power. A person holding only a Tax Information Authorization cannot sign a return, negotiate a payment plan, argue a penalty case, or otherwise act on the taxpayer’s behalf in dealings with the IRS — the list of Power of Attorney powers that the tax tip spells out (representing, advocating, negotiating and signing) applies only to Form 2848, not to Form 8821.
Filing Through the Tax Pro Account or Individual Online Account
A separate IRS release the following day, IR-2026-102, dated Aug. 28, 2026, detailed how much of this authorization process can now move online. Tax professionals can use the IRS’s Tax Pro Account to request power of attorney and tax information authorizations, check the status of a request, view active authorizations, and withdraw one. When both the tax professional and the taxpayer have IRS online accounts, the taxpayer can view, approve and electronically sign certain authorization requests from inside their own Individual Online Account rather than mailing or faxing a signed paper form.
That online path is built around a credentialed tax professional initiating the request — it does not turn an ordinary family member into an authorized representative on its own. A caregiver who is not an attorney, CPA or enrolled agent generally still works through the paper Form 8821 process, or relies on a hired tax professional to file Form 2848 and manage the case.
Ending the Authorization Once a Parent No Longer Needs Help
Per the same Aug. 27 tax tip, a Power of Attorney “stays in place until the taxpayer revokes the authorization or the representative withdraws it,” and a Tax Information Authorization “stays in effect until it is revoked by the taxpayer or the designee withdraws it.” Neither one expires on its own schedule, which means an authorization filed years earlier — for a tax season when a parent needed extra help, or during a hospital stay — can remain active long after the need has passed unless someone formally revokes it.
The guidance also describes narrower, shorter-lived options for a single phone call or one-time conversation: a Third Party Designee checked off directly on a tax return, which generally expires a year after that return’s due date, and an oral disclosure authorized in the moment, which ends automatically once that specific call or meeting is over. For an ongoing arrangement like managing a parent’s tax matters, though, Form 2848 and Form 8821 remain the two documents that carry lasting weight with the IRS, and the difference between them — the power to act versus the ability to look — is the detail worth getting right before either one is signed.
