IRS Form 8821: A Tax Information Authorization Guide

Generally speaking, Section 6103(c) of the Internal Revenue Code requires the Internal Revenue Service to take appropriate steps to protect a taxpayer’s confidential tax information. However, there might be times when a taxpayer facing IRS issues wants to disclose their personal tax information to a third party, such as a tax professional. Filing IRS Form 8821 allows the taxpayer to do just that.

In this article, we’ll cover IRS form 8821, to include:

  • Why taxpayers might want to use this tax form
  • How to complete Form 8821
  • Other options that a taxpayer may use to share their confidential information with tax professionals

Let’s start with some basic information on the tax form itself.

What is IRS Form 8821?

IRS Form 8821, Taxpayer Information Authorization, is the official IRS form that taxpayers may use to authorize the IRS to release specific account information to a third party. Taxpayers may also use this form to revoke prior tax information authorizations.

Who can file IRS Form 8821?

Any taxpayer may file this form with the IRS to authorize the release of specific information, such as tax returns, to any individual, corporation, firm, organization, or partnership they choose.

Does IRS Form 8821 authorize tax practitioners to do anything on behalf of their clients?

While this tax form authorizes the release of tax information, it does not authorize that third party to be an authorized agent of the taxpayer or to act as a representative on any tax matter. The form instructions clearly state that Form 8821 does not authorize a designee to:

  • Speak on your behalf
  • To execute a request to allow disclosure of return or return information to another third party
  • To advocate a taxpayer’s position regarding federal tax laws
  • To execute waivers, consents, closing agreements, or
  • To represent you in any other manner before the IRS

When should I NOT use IRS Form 8821?

There are some situations which call for different types of requests not covered by this tax form.

Power of attorney

Taxpayers who wish to appoint a someone as a representative before the IRS should file IRS Form 2848, Power of Attorney and Declaration of Representative, instead of the tax information authorization form. Completing the power of attorney form is more appropriate for a tax situation which requires the tax expert to act on the taxpayer’s behalf in representative matters.

Fiduciary relationships

If you wish to disclose a fiduciary relationship, you should instead file IRS Form 56, Notice Concerning Fiduciary Relationship. In a fiduciary relationship, the specified person acts as the taxpayer, not as the taxpayer’s representative.

Release of tax transcripts or tax returns from previous tax years

If you’re simply looking to obtain copies of previous returns or tax information related to those returns, the easiest way to obtain them is to file one of the following forms:

  • IRS Form 4506, Request for Copy of Tax Return
  • IRS Form 4506-T, Request for Transcript of Tax Return
  • IRS Form 4506T-EZ, Short Form Request for Individual Tax Return Transcript

Please note: there may be additional fees associated with obtaining additional copies of previous income tax returns.

How do I complete IRS Form 8821?

We’ll walk through this one-page tax form, step by step. There are only 6 fields that you need to complete.

Line 1: Taxpayer information

Enter the following information:

  • Taxpayer name and mailing address
  • Taxpayer identification number(s) (TIN)
  • Daytime telephone number

Individuals

If your taxpayer status is married, filing jointly, this authorization will only be for the spouse listed on this form. You must submit a separate Form 8821 to release tax information for your spouse or former spouse.

Employee plan or exempt organization

Enter the three-digit plan number, if available.

Estate

If the estate does not have a separate TIN, then enter the decedent’s Social Security number or TIN.

Line 2: Designee(s)

For each designee, enter the designee’s full name, mailing address, telephone number and fax number.

Also enter the 9-digit CAF number for the designee and preparer tax identification number (PTIN), if available.

Should the designee have a CAF number from a previously filed Form 8821 or Form 2848, use that CAF number. In cases where the designee does not have a CAF number, enter ‘NONE’ in the CAF number field and the IRS will assign a CAF number to the designee.

If you wish to name more than two designees, check the appropriate box and attach a list to the completed form. This list must contain the requested information for each additional designee.

Check the appropriate box(es) for any of the following:

  • You wish the designee receive copies of IRS notices and communications that you receive
    • No more than 2 designees
  • Any designee has updated any of the following from their most recent IRS filing:
    • Address
    • Telephone number
    • Fax number

Line 3: Tax information

In this next step, you must specify the tax information that you are authorizing:

Column (a): Type of tax information

Enter the type of tax information here. Examples include:

  • Income tax information
  • Employment tax information
  • Payroll tax information
  • Excise tax
  • Gift tax

Column (b): Tax form number

Enter the tax form number, such as Form 1040, or Form 720, that you wish to release.

Column (c): Year(s) or Period(s)

You may enter specific years or tax periods (such as tax quarters for quarterly returns)

Column (d): Specific tax matters

If you wish to limit your appointee’s authority to receive or inspect all of the requested tax information, specify the information here. Otherwise, you may enter “not applicable” to authorize your designee to receive all of the requested information.

What you may specify

Multiple years or periods: You can specify more than one year or period. For example, to grant access for tax years 2018 through 2021, you would simply enter, “2018-2021.”

Note that listed dates are considered to be inclusive, not exclusive. In other words, entering “2018-2021” would authorize the release of information related to tax years 2018 and 2021.

Future periods: You can specify future tax years or periods. However, the IRS will not release information for tax periods more than 3 years after December 31 of the year that you file. For example, if you submit a request in January 2023, the IRS will not release any information for tax years or periods beginning in 2027.

Use of an intermediate service provider (ISP): You can authorize access to your IRS records via an ISP by checking the appropriate box.  If you do not do this, your designee can still access the requested information through the IRS e-Services Transcript Delivery System.

What you may NOT specify

Blanket requests: The IRS will not consider overly broad, general requests, such as “all tax years,” “all forms” or “all tax matters.” Instead, the IRS will send this form back to the requestor.

Line 4: Specific use not recorded on the Centralized Authorization File (CAF)

There is certain tax information that the IRS does not record on the CAF. If the authorization is for one of the following purposes, check this box and skip Line 5:

If you check this box, your designee should mail or fax a completed Form 8821 to the IRS office handling the matter. Otherwise, your designee should bring a copy of Form 8821 to each appointment to inspect or receive information. A specific-use tax information authorization will not revoke any prior tax information authorizations.

Line 5: Retention or revocation of prior tax information authorizations

If you checked the box in Line 4, skip this field. The IRS will automatically revoke all prior tax authorizations on file, unless you:

  • Check the box in Line 5
  • Attach a copy of all tax authorizations that you wish to retain

If you want to revoke a prior tax information authorization without submitting a new authorization, simply write “REVOKE” across the top of the authorization that you wish to revoke. For taxpayers who do not have a copy of the prior authorization and it is not a specific use authorization, then send a letter to the appropriate IRS location with the following information:

  • A statement that you are revoking the designee’s authority
  • Name and address of each designee whose authority is being revoked,
  • Related tax matters and tax periods, and
  • Dated signature

Line 6: Taxpayer signature

In Line 6, sign and date the form. Beneath your signature, clearly print your full name and title, if you have one.
