IRS Form 2848: How to Fill Out and Sign Power of Attorney

Form 2848, Power of Attorney and Declaration of Representative, lets you authorize someone else, an accountant, an enrolled agent, or an immediate family member, to speak with the IRS on your behalf and access your tax records. Most guides online are written for tax preparers filing on behalf of dozens of clients. This one is written for you: the person filling this out once, by hand, to let a parent, spouse, or accountant deal with a tax problem for you.

What Form 2848 Actually Authorizes

Form 2848 grants a specific person the right to represent you before the IRS for the tax matters, forms, and years you list on the form. That can include receiving copies of your IRS notices, discussing your account with an IRS agent, and, if you check the box for it, signing certain documents on your behalf. It does not give the representative access to your bank accounts or the ability to sign your tax return unless you specifically authorize that.

It is different from Form 8821, Tax Information Authorization, which only lets someone see your tax information without the power to argue your case or negotiate with the IRS. If your parent just needs their accountant to explain a notice to you, 8821 might be enough. If you need someone to actually resolve an audit or set up a payment plan on your behalf, you need Form 2848.

Who Should (and Shouldn't) Use It

You should use Form 2848 if you want someone else to deal directly with the IRS about an audit, a collection notice, an amended return, or a specific tax year where you are not available or not comfortable handling it yourself. Common situations include an adult child helping an elderly parent respond to an IRS letter, a spouse handling a joint return issue while the other spouse is deployed or hospitalized, or a small business owner authorizing their bookkeeper to answer a notice.

Not everyone qualifies as a representative. The IRS only allows specific categories: attorneys, CPAs, enrolled agents, enrolled actuaries, officers of a company for its own tax matters, unenrolled return preparers under limited conditions, and one category built for exactly the situation above, an immediate family member (spouse, parent, child, grandparent, grandchild, or sibling). If you are naming a family member under that designation, they do not need a CAF number, a PTIN, or any professional credential. You simply write "None" on the CAF number line and the IRS assigns one after processing.

If you and your spouse file jointly and both of you want the same person to represent you, each spouse must complete and sign a separate Form 2848. The IRS will not process one form covering both spouses.

Step by Step: Filling Out Form 2848

Form 2848 is two pages. You can fill in every field directly in your browser without printing anything first by uploading the blank form at Fill PDF and typing straight into the fields.

1. Line 1, Taxpayer Information. Enter only your own name, address, and Social Security number (or ITIN or EIN for a business). Do not add a spouse's information here even on a joint return.
2. Line 2, Representative. Enter the full name, mailing address, and CAF number of the person you are authorizing. If they do not have one, write "None". Check the box for their designation (letter f covers immediate family members).
3. Line 3, Acts Authorized. This is the part people rush and get wrong. List the specific matter (for example "Income"), the tax form number (1040), and the year or period. If you write "All years" the IRS will reject it. The form only lets you go back three years plus any future periods, so if this is about a notice for your 2024 return, write 2024, not a range.
4. Line 4. Only check this if a specific IRS office told you to send this form to them directly instead of the CAF unit.
5. Line 5a and 5b. Use these to authorize or restrict specific acts, like signing a return or receiving refund checks. Leave blank if you only want the representative to discuss and negotiate, not sign anything.
6. Line 6 and 7. Line 6 lets you revoke a prior authorization for the same matter. Line 7 is where you sign, print your name, and date it. On a joint return, each spouse signs their own separate form.
7. Part II, Declaration of Representative. The representative fills in their designation letter, jurisdiction (their state, if an attorney or CPA), and signs and dates page 2. A family member representative writes "f" and their relationship to you instead of a license number.

Part I vs Part II Explained in Plain English

Part I is your side of the form: who you are and who you're authorizing. Part II is the representative's side: their credentials and their signature confirming they agree to represent you. Both parts have to be complete or the IRS will bounce the whole form back, which is the single most common reason a 2848 gets rejected. If you're filling this out together with your representative, which is common for family authorizations, do it in one sitting so nobody signs an incomplete form.

Once both signatures are in place, you can add them electronically instead of printing and scanning. Sign PDF lets both the taxpayer and the representative add a typed or drawn signature to the same document without mailing pages back and forth first.

How to Sign and Submit It to the IRS

You have three ways to get a completed Form 2848 to the IRS:

• Fax. The CAF unit fax number depends on where you live: the Memphis unit generally covers eastern states, Ogden covers western states, and Philadelphia handles international cases. Check the current list on the IRS Form 2848 instructions page before sending, since regional assignments have changed in past years. Include a cover sheet labeled "Form 2848."
• Mail. Slower, usually two to four weeks during filing season, but useful if you don't have fax access.
• Online upload. The IRS's "Submit Forms 2848 and 8821 Online" tool at IRS.gov/submit2848 accepts a scanned or electronically signed PDF and is generally the fastest non-Tax-Pro-Account option, with confirmation of receipt.

Processing typically takes three to five business days outside of tax season, but stretches to two to four weeks during March and April, so send it as early as you can once the underlying issue comes up. Keep a copy of the signed form and the fax confirmation or upload receipt for your own records; the IRS will not send you a confirmation copy back.

If you're helping a parent or a client with more than just this one form (say, a Form 8822 change of address or a copy of a notice that needs redacting before you share it with a sibling), it's worth having one place to fill, sign, and store all of it. A One Week Plan costs $3 as a one-time charge and covers exactly this kind of short, one-off task, filling and signing a handful of documents in a single week, with nothing to cancel afterward since it simply expires. That's a meaningfully different commitment than a monthly subscription you'd have to remember to cancel once the tax issue is resolved.

FAQs

Can a family member sign Form 2848 as my representative without any tax credentials?

Yes. The IRS lists "immediate family member" as its own representative designation on the form, covering a spouse, parent, child, grandparent, grandchild, or sibling. They write "None" on the CAF number line and the IRS assigns one after the form is processed.

How long does a Form 2848 authorization last?

It stays in effect for the specific tax matters and years you listed until you revoke it, the representative withdraws, or the matter resolves. You can also set an expiration by writing a specific end date on Line 5b.

What's the difference between Form 2848 and Form 8821?

Form 2848 lets your representative speak and negotiate with the IRS on your behalf. Form 8821 only lets someone view your tax information; they cannot argue your case or sign anything for you.

Do both spouses need to file Form 2848 for a joint return?

Yes. Each spouse completes, signs, and submits their own separate Form 2848, even if you're both authorizing the same representative for the same joint return.

What happens if I leave a section of Part II blank?

The IRS will reject the entire form and mail it back unprocessed. Both Part I (your section) and Part II (the representative's declaration and signature) must be fully completed before you submit it.
