IRS Form 8821
Tax Information Authorization
Form 8821 is the IRS's information-only authorization. It lets a third party — typically a mortgage lender verifying income, a bank underwriting an SBA loan, or an accountant pulling transcripts — receive copies of your tax returns, transcripts, and account information. Unlike Form 2848, it does NOT give the recipient any authority to advocate, negotiate, or sign anything for you. It is read-only access.
Taxpayers applying for mortgages, SBA loans, or commercial financing where the lender requires direct IRS transcript verification; clients who want their accountant to monitor IRS account activity; estate executors needing access to a decedent's IRS file.

What's at Stake With Form 8821
A defective 8821 delays lending decisions and can kill a loan closing. Granting an overly broad authorization (all years, all forms) means the third party can pull anything in your IRS file forever, including future years, until you revoke it. The IRS posts every 8821 to the CAF, and unrevoked authorizations are a privacy liability.
How to File Form 8821 Correctly
- 1Use the taxpayer name and SSN/EIN exactly as on the return
Mismatches between Form 8821 and IRS records cause the request to bounce and the lender to ask for a re-filed form.
- 2List the specific years and forms required
Most lenders need Form 1040 for the last two tax years and W-2/1099 transcripts. Limiting scope to exactly what's needed is best practice.
- 3Enter the recipient's full information and CAF number if they have one
Lenders and banks usually have a standing CAF number. Without it, the IRS may still process the form but tracking is harder.
- 4Decide whether to allow disclosure of confidential return information
Line 5 controls whether the IRS can share return data verbally over the phone with the third party. Most lenders want this; tighten it for accountant-only access.
- 5Submit via Submit Forms 2848 and 8821 Online — or fax to CAF
Online submission posts within 48 hours typically. Fax is reliable but slower. Mail is the last resort for loan-closing timelines.
Why File Form 8821 With a Tax Attorney
Once you sign IRS paperwork, every fact you disclosed becomes evidence. Privilege protects the conversation before you commit.
Collection Financial Standards, RCP math, and ACS vs. Field Collection rules change what number you should put on this form.
Direct-debit triggers, dissipated-asset addbacks, AMT preference items — most of the cost of these forms is in what you didn't know to negotiate.
If the IRS rejects, defaults, or audits you off this form, we represent you through Appeals, Tax Court, or U.S. District Court.
Costly Mistakes With Form 8821
Granting authorization for 'all years' when the lender only needs two.
Failing to revoke 8821s after a loan closes — the recipient keeps reading IRS notices.
Confusing 8821 with 2848 and assuming the accountant can represent you at audit.
Listing the wrong form numbers — lenders need 1040, not 1120 unless it's a business loan.
Forgetting to date the form — undated 8821s are rejected.
Frequently Asked Questions About Form 8821
No. Form 8821 is information-only. The recipient can read your IRS file but cannot speak for you, negotiate, sign anything, or attend an audit on your behalf. For that, you need Form 2848.
Write 'REVOKE' across a copy of the original 8821, sign and date it, and submit to the CAF Unit. Or file a new 8821 with the revocation box checked. Until revoked, the original authorization lives forever in the CAF.
Yes — and most do. Form 4506-C is the income-verification form mortgage lenders use to pull tax transcripts directly from the IRS. Form 8821 is broader: it gives ongoing access to the IRS account, not just one-time transcript retrieval.
No. It only applies to federal tax information. State revenue agencies have their own disclosure authorization forms.
