Form 2848, Form 8821, and the 2290 Third Party Designee

Filing Form 2290 for a client raises a practical question: how much authority do you actually need, and which form grants it? The IRS gives you three distinct levels, and picking the right one keeps you inside your authority without asking the client to sign more than the job requires.

The 2290 third party designee

The lightest option lives on Form 2290 itself. By checking the third party designee box and naming a person with a five digit PIN, the client authorizes that one person to discuss that one return with the IRS. It lets you answer questions and sort out a processing issue on the return you filed. It does not let you represent the client more broadly, and it expires one year after the return's due date.

Form 8821, Tax Information Authorization

Form 8821 lets you receive and inspect a client's confidential tax information for the periods and tax types you list. It is an information authorization, not a representation one. You can pull transcripts and see what the IRS has on file, which is often exactly what you need to reconcile a client's account, but you cannot advocate for the client or sign on their behalf. Anyone can be named on an 8821, not only a credentialed preparer.

Form 2848, Power of Attorney

Form 2848 is the full grant. It authorizes you to represent the client before the IRS: to advocate, to respond to notices, and to sign certain documents within the scope you list. Because it is representation, only eligible practitioners can be named, such as CPAs, enrolled agents, and attorneys. This is the form you want when a client's matter has gone beyond a single return into a dispute or an examination.

Which one do you need?

• Just filing a client's 2290 and want to clear up a question on it: the third party designee box is usually enough.
• Need to pull transcripts or see the client's IRS account, but not represent them: Form 8821.
• Need to represent the client, respond to notices, or handle an examination: Form 2848.
• Not sure it will stay simple: many firms put an 8821 or 2848 on file up front so they are not scrambling for authority when a notice arrives.

It does not change what each form grants, only how quickly you can get it on record.
