IRS Form 15426 – IRS Forms, Instructions, Pubs 2026 – In the realm of tax administration and intergovernmental cooperation, efficient data sharing is crucial for compliance and operational effectiveness. One key tool facilitating this is IRS Form 15426, also known as the IRS Governmental Liaison (GL) Data Exchange Request. This form plays a vital role in initiating collaborations between the Internal Revenue Service (IRS) and various stakeholders. Whether you’re a government agency, internal IRS unit, or external partner seeking to exchange tax-related data, understanding Form 15426 is essential. This article provides an in-depth, SEO-optimized overview, drawing from official IRS sources to ensure accuracy and relevance as of 2026.
What Is IRS Form 15426?
IRS Form 15426 is an initial intake document designed to formalize requests for data exchanges involving tax return and tax return information. It serves as the starting point for establishing agreements between IRS business units (BUs) and external entities, such as federal, state, or local government agencies. The form was revised in April 2025, reflecting updates to streamline the process of capturing essential details for collaborative initiatives.
Unlike standard tax filing forms, Form 15426 is not for individual taxpayers but for institutional use. It’s part of the IRS’s broader Governmental Liaison operations, which aim to enhance partnerships for tax compliance and data security. The form ensures that all proposed data exchanges comply with IRS privacy, disclosure, and safeguard requirements.
Purpose of IRS Form 15426
The primary purpose of Form 15426 is to initiate the agreement development process for data exchanges. It captures key information needed to evaluate and approve collaborations, including:
- New data exchanges between the IRS and external stakeholders.
- New data matching agreements.
- Novel uses of existing exchanged data.
- Joint compliance activities managed by IRS business units.
By requiring this form before any formal agreement begins, the IRS ensures structured, secure, and compliant data sharing. This helps prevent unauthorized disclosures and aligns with federal regulations under sections like IRC 6103, which governs the confidentiality and disclosure of tax returns.
For instance, state tax agencies might use this form to request access to federal tax data for matching purposes, aiding in identifying non-filers or underreporters. The form’s role in pre-approval processes underscores its importance in maintaining the integrity of tax administration.
Who Should Use IRS Form 15426?
Form 15426 is intended for use by:
- Internal IRS business units seeking to collaborate with external parties.
- External stakeholders, including federal, state, and local government agencies.
- Any entity involved in joint initiatives requiring tax data exchange, such as law enforcement or regulatory bodies.
It’s not applicable for private businesses or individuals unless they are part of a government-sanctioned program. The Governmental Liaison (GL) office typically handles the form’s processing, assigning specialists or analysts to oversee the request. If you’re a government entity looking to establish or modify a data-sharing agreement with the IRS, this form is your entry point.
How to Complete IRS Form 15426?
Completing Form 15426 requires providing detailed information to facilitate the IRS’s review. While specific field-level instructions are integrated into the form itself (available via official IRS channels), here’s a general step-by-step guide based on IRS guidelines:
- Identify the Requester and Stakeholders: Enter details about the requesting IRS business unit or external agency, including contact information, initiative goals, and involved parties.
- Describe the Data Exchange: Specify the type of data requested (e.g., tax returns, transcripts), the purpose (e.g., compliance matching), and any new uses or joint activities.
- Outline Security and Compliance Measures: Detail how the data will be safeguarded, including adherence to IRS privacy rules and identity assurance protocols.
- Provide Supporting Details: Include information on the scope, such as data volume, frequency of exchange, and legal basis (e.g., referencing IRC sections).
The form emphasizes capturing “key information” to support agreement development, so be thorough yet concise. It’s advisable to consult with a GL specialist for guidance, as the process involves review by IRS Disclosure Managers and Procedure & Administration (P&A) Counsel.
Common tips for filling out the form:
- Use clear, professional language.

- Initial Review: The form is evaluated for completeness and compliance.
