Tax information privacy is something I take seriously on both sides – protecting client data and helping clients authorize disclosures when they need to. Form 15426 comes up most often when a client needs to provide income verification to a lender, a government program, or a contracting entity that needs something more specific than a commercial tax transcript. Getting the form right the first time prevents the IRS from returning it for corrections during a deadline-sensitive process.
Key Takeaways
- Form 15426 is a formal IRS disclosure request form that authorizes the IRS to provide specific tax return information to a designated third party based on taxpayer consent and applicable legal authority under IRC § 6103.
- Who uses it: Taxpayers (or their authorized representatives) who need to authorize the IRS to share specific tax information with a third party for a defined purpose such as income verification, government program eligibility, or financial qualification.
- Taxpayer consent is required: The IRS will not process a disclosure request under Form 15426 without the taxpayer’s authorized signature – IRC § 6103 strictly protects return information from unauthorized disclosure.
- Not the same as Form 4506-C: Form 4506-C is used for transcript requests by lenders and financial institutions. Form 15426 covers third-party disclosure requests in contexts governed by different IRC § 6103 exceptions.
- Processing is not immediate: Allow several weeks for IRS processing. Do not submit this form for time-critical disclosures without accounting for processing time.
- SOP tip: Build a review step for completeness – missing fields are the most common reason Form 15426 is returned without action. Check every field before submitting.
What Form 15426 Is and When to Use It
Form 15426, “Request to Disclose Tax Information to a Third Party,” is an IRS form used to formally request that the IRS share specific tax return information with a designated third party. The legal framework for this disclosure is IRC § 6103, which establishes the general rule of confidentiality for tax returns and return information – and then provides a specific set of exceptions under which disclosure is permitted.
Tax returns and return information are among the most strictly protected categories of federal data. IRC § 6103 prohibits IRS employees from disclosing return information except in circumstances explicitly authorized by law. One of those authorized circumstances is taxpayer consent – when a taxpayer explicitly authorizes disclosure through a properly completed request form, the IRS may make the disclosure to the authorized recipient. Form 15426 is the mechanism through which this consent-based disclosure is formally requested.
The form is used in situations where a third party needs specific tax information that is not available through a standard tax return transcript (Form 4506-C) or where the disclosure is governed by a particular IRC § 6103 exception rather than the general transcript request framework. Common scenarios include income verification for government programs that require specific IRS data, disclosures to designated financial institutions for loan qualification purposes under specific statutory authority, and other situations where a direct IRS disclosure is the required or most appropriate mechanism.
How This Differs From a Power of Attorney
A Form 2848 (Power of Attorney) authorizes a representative to act on the taxpayer’s behalf before the IRS – it does not authorize the IRS to disclose return information to a third party. Form 15426 is specific to consented third-party disclosures. If a client needs their practitioner to receive return information from the IRS, a Form 8821 (Tax Information Authorization) is typically the appropriate form. Form 15426 is used when the disclosure is going to someone other than the taxpayer or their representative.
When Form 15426 Is the Right Tool
Form 15426 applies when a specific program, lender, or government agency requires a direct IRS disclosure rather than a taxpayer-provided transcript or copy. The form is also used when the applicable IRC § 6103 exception requires specific IRS authorization documentation rather than a general transcript request. If you are unsure whether Form 15426 or Form 4506-C is the right tool for a specific disclosure need, review the requirements of the receiving organization and the applicable legal authority for the disclosure.
How to Complete Form 15426
Form 15426 collects identifying information about the taxpayer, the specific information being requested, and the designated third-party recipient. Completeness is critical – incomplete forms are returned without action.
| Field | What to Provide | Practitioner Tip |
|---|---|---|
| Taxpayer Name and SSN/EIN | Full legal name and identifying number of the taxpayer whose return information is being disclosed | Exact match to IRS records; for business entities, use the entity name and EIN as they appear on filed returns |
| Tax Year(s) Covered | Specific tax years for which disclosure is authorized | Specify years precisely; a vague or overly broad year range may not be processable |
| Type of Information Requested | Specific description of the tax information to be disclosed (e.g., income figures, filing status, specific line items) | Be as specific as possible; overly broad requests will be denied or returned for clarification |
| Third-Party Recipient | Full legal name and address of the organization or individual to receive the disclosed information | Confirm the recipient’s information is accurate – the IRS will not redirect to an alternative if the address is wrong |
| Purpose of Disclosure | Explanation of why the disclosure is needed and what statutory authority supports it | Reference the specific IRC § 6103 subsection if applicable – vague purpose statements delay processing |
| Taxpayer Signature and Date | Authorized signature of the taxpayer (or authorized representative where applicable); date | Both signature and date are required – the date must be current, not stale |
Where to Submit
Form 15426 is submitted to the appropriate IRS office based on the nature of the disclosure request. The IRS instructions for the form specify submission addresses based on the type of information being requested and the applicable statutory authority. Confirm the current submission address before mailing – IRS office locations for specialized form processing change periodically.
Filing and Processing Requirements
Form 15426 does not have a fixed statutory filing deadline because it is not a tax return or information return – it is a request form. However, timing matters significantly in practice.
| Requirement | Detail |
|---|---|
| Processing Time | Typically several weeks; may be longer during peak IRS workload periods |
| Submission Method | Paper submission to the applicable IRS office; confirm current address from IRS instructions |
| Completeness Requirement | Incomplete forms are returned without action; the clock does not run on an incomplete submission |
| Signature Validity | Signatures must be current and not stale-dated; check for any IRS guidance on signature validity periods |
| Tracking | Submit by certified mail with return receipt to create a submission record; the IRS does not typically acknowledge receipt of Form 15426 |
What Happens After Submission
The IRS reviews the request to confirm that all required information is present, that the taxpayer’s consent is properly documented, and that the requested disclosure is within the scope of what is permitted under the applicable IRC § 6103 authority. If the request is complete and authorized, the IRS processes the disclosure to the designated third party. If information is missing or the request is outside permissible scope, the IRS will return it with a notice of what is needed. There is no online tracking mechanism for Form 15426 requests – practitioner follow-up may be required by phone.
IRC Section 6103 and the Legal Framework
Understanding the legal framework behind Form 15426 helps practitioners advise clients and process requests correctly.
The General Rule of Tax Return Confidentiality
IRC § 6103(a) establishes that returns and return information are confidential and that IRS officers and employees may not disclose them except as authorized by the Code. This is one of the strongest data privacy protections in federal law, and violations carry civil and criminal penalties for IRS personnel. The form-based disclosure request process exists precisely because the IRS needs a formal authorization record before it can act on a disclosure request.
Permitted Disclosures Under Section 6103
IRC § 6103 contains numerous subsections authorizing specific categories of disclosure – to taxpayers themselves (§ 6103(e)), to authorized representatives (§ 6103(e)(6)), to other federal agencies for specific purposes (§ 6103(l)), and in connection with judicial and administrative proceedings (§ 6103(h)). Form 15426 is most commonly used in contexts governed by § 6103(c) (disclosure with taxpayer consent) or specific subsections of § 6103(l) (disclosures to certain agencies and programs).
What Taxpayer Consent Authorizes
Under IRC § 6103(c), a taxpayer can consent to disclosure of their return information to a third party. The consent must be in writing, must identify the specific information to be disclosed, must identify the recipient, and must be signed by the taxpayer. Form 15426 is designed to capture all of these elements in a structured format that the IRS can verify and process.
Common Use Cases for Third-Party Disclosure Requests
Form 15426 arises in a specific set of practical contexts that practitioners should recognize.
Government Program Eligibility Verification
Various federal and state programs require income verification from IRS records as a condition of eligibility. While many housing programs use the 15417 series of consent forms for this purpose, other government programs – such as certain federal contracting programs, student loan programs, or grant-funded programs – may require the more general Form 15426 framework for income data requests that fall outside the specific housing program disclosure channels.
Financial Institution and Lender Requirements
Some specialized lending contexts require a direct IRS disclosure rather than a borrower-provided transcript. While Form 4506-C covers the standard mortgage transcript request used by most lenders, there are lending scenarios where the applicable regulatory requirement or investor guideline specifies a different disclosure mechanism. In those cases, Form 15426 may provide the appropriate authorization framework.
Business and Contract Qualification
Federal contracts and some state procurement processes require contractors to verify their tax compliance status. Income or return information requests for this purpose may be made through Form 15426 where the applicable program requirements specify a direct IRS disclosure rather than a contractor-provided document.
Form 15426 vs. Form 4506-C and Other Disclosure Methods
Practitioners frequently encounter questions about which form to use for different disclosure scenarios. This overview clarifies the distinctions.
| Form / Method | Primary Use | Recipient |
|---|---|---|
| Form 4506-C | Transcript request for lenders and financial institutions via the Income Verification Express Service (IVES) | Lenders, banks, financial institutions using IVES |
| Form 4506 | Request for actual copy of tax return (not transcript) | Taxpayer or authorized representative |
| Form 8821 | Tax Information Authorization – allows the IRS to discuss or send information to the authorized person | Designated individual or firm (usually the taxpayer’s representative) |
| Form 15426 | Formal request for specific IRS disclosure to a third party under IRC § 6103 consent or other authority | Designated third party as specified on the form |
| 15417 Series (D, F, G, H) | Housing-specific income verification disclosure to housing agencies | HUD, state housing agencies, HFAs, or Tribal Housing Authorities |
Quick rule you can copy into your SOP: if the third party receiving the information is a housing agency using IRS income matching, use the appropriate 15417 series form. If the third party is a financial institution using the standard transcript process, use Form 4506-C. For other third-party disclosures requiring IRS authorization under IRC § 6103, Form 15426 is likely the applicable form.
Taxpayer Rights and Privacy Protections
Form 15426 touches core taxpayer privacy rights, and practitioners should understand these protections when advising clients.
The Right to Control Your Tax Information
Under the Taxpayer Bill of Rights, taxpayers have the right to privacy and the right to know why the IRS is asking for information. The consent-based disclosure framework in IRC § 6103(c) reflects this right – the taxpayer controls whether their tax information is shared with third parties through written, specific authorization. No third party can compel the IRS to disclose return information simply by requesting it; the taxpayer’s consent is required.
Scope Limitations Protect the Taxpayer
The IRS interprets disclosure authorizations narrowly. Even with a signed Form 15426, the IRS will disclose only the specific information identified in the request for the identified purpose. The IRS will not disclose additional information beyond the scope of the consent, and the recipient is prohibited from using the information for purposes other than those identified in the request.
Revoking Consent
A taxpayer can revoke a consent to disclose at any time before the IRS acts on it. Once the disclosure has been made, however, it cannot be recalled. This underscores the importance of the taxpayer understanding exactly what they are authorizing before they sign Form 15426 – the decision should be made with full information about what will be shared, with whom, and for what purpose.
Common Mistakes That Slow Things Down
- Submitting an incomplete form – Missing fields are the most common reason Form 15426 is returned without action. Check every required field before submitting.
- Using the wrong form for the disclosure type – Housing program disclosures use the 15417 series. Standard mortgage transcripts use Form 4506-C. Confirm the applicable form before collecting signatures.
- Vague description of information requested – “All tax information” is not processable. Specify the exact data points needed (e.g., adjusted gross income for years X, Y, Z).
- Stale or undated signatures – The IRS will not process requests with missing or clearly stale signatures. Date the form contemporaneously with signature.
- Not accounting for IRS processing time – Form 15426 takes weeks to process. Submitting the day before a deadline guarantees a problem.
- Submitting to the wrong IRS address – Confirm the current submission address from IRS instructions before mailing; addresses for specialized form processing change.
- Not retaining a copy and proof of submission – Submit by certified mail with return receipt and retain copies of the submitted form and mailing documentation.

For Accounting Firms – Keep Delivery Smooth While You Scale
Managing tax information disclosure requests for clients requires attention to legal authority, form selection, completeness standards, and tracking – all of which are documentation discipline issues that scale poorly when handled informally. Accountably supports CPA and accounting firms with structured delivery processes that bring systematic discipline to exactly these kinds of recurring, document-intensive client service tasks.

FAQs About Form 15426
What is Form 15426 used for?
Form 15426 is used to request that the IRS disclose specific tax return information to a designated third party based on the taxpayer’s consent and the IRS’s authority under IRC § 6103. It is applicable in contexts where a direct IRS disclosure to a third party is required and where the disclosure authority is based on taxpayer consent or a specific IRC § 6103 exception.
How is Form 15426 different from Form 4506-C?
Form 4506-C is used specifically for income transcript requests through the IRS Income Verification Express Service (IVES), primarily by mortgage lenders and financial institutions. Form 15426 is a separate mechanism for third-party disclosure requests in contexts not covered by the standard transcript process, where the applicable IRC § 6103 authority requires formal consent documentation or where the disclosure is going to an entity outside the IVES framework.
Does the taxpayer have to consent to the disclosure requested on Form 15426?
Yes. IRC § 6103 generally prohibits the IRS from disclosing return information without legal authority. Where the disclosure is consent-based, the taxpayer’s signed authorization is required. Without the taxpayer’s authorization, the IRS cannot process the request regardless of the third party’s stated need for the information.
How long does it take for the IRS to process a Form 15426 request?
Processing times vary depending on the IRS’s current workload and the complexity of the request. Practitioners should allow several weeks for processing and plan accordingly for any time-sensitive disclosure needs. There is no online tracking mechanism, so follow-up by phone may be required if no response is received within six to eight weeks.
What information can be requested through Form 15426?
The scope of information that can be disclosed depends on the specific IRC § 6103 authority under which the request is made and the taxpayer’s consent. Requests must identify specific data points rather than requesting the taxpayer’s complete tax file. The IRS will not fulfill requests that exceed the scope of the applicable disclosure authority or the taxpayer’s specific authorization.
