1. Introduction – What is Publication 6025?
IRS Publication 6025, titled “Secure Messaging: Contact the IRS through Secure Messaging User Guide” (Catalog Number 95343I), is the official instruction manual for taxpayers and representatives communicating directly with the Internal Revenue Service online. Instead of relying on paper mail or long phone calls, this digital guide explains how to communicate through the agency’s encrypted communication portals.
According to current IRS records and official directory listings through 2026, the foundational release for this document is the Revision dated February 2025 (Rev. 2-2025, posted February 28, 2025). As the IRS continues expanding online taxpayer portals—including major rollouts such as the July 2026 Business Tax Account updates—Publication 6025 remains the active operational guide governing secure digital taxpayer correspondence throughout 2026.
The publication walks users through logging into IRS portals, accepting platform terms, composing secure inquiries, attaching required documentation, and reviewing responses from IRS staff. It provides an efficient and legally protected path to resolve tax inquiries quickly.
2. Who Should Read This Publication
Publication 6025 is designed for anyone who needs to exchange documents or communicate directly with an IRS agent without using standard postal mail. If you prefer handling tax matters from your computer or smartphone, this guide is written for you.
- Individual Taxpayers: Anyone resolving an identity verification request, exam inquiry, or IRS notice who wants to upload records securely.
- Small Business Owners: Entrepreneurs managing federal tax inquiries through their IRS Business Tax Account or handling clean energy credits.
- Tax Professionals: Certified Public Accountants (CPAs), Enrolled Agents (EAs), and tax attorneys who represent clients and need to manage correspondence threads.
- Nonprofit and Entity Administrators: Representatives managing pre-filing registrations or elective payment credit inquiries under federal incentive programs.
3. Key Topics Covered
The user guide covers every step of the digital messaging process from your first login to case resolution. It sets clear ground rules so both taxpayers and IRS staff protect sensitive financial data.

4. Detailed Breakdown of Main Concepts
Accepting the Terms of Service
The first time you access the IRS Secure Messaging platform, you must accept the official Terms of Service and Rules of Conduct. This step establishes legal expectations for digital conduct and confirms that the user is authorized to share taxpayer data. If you decline the terms, you cannot use digital messaging and must use phone or paper communications.
Navigating the Messaging Dashboard
Once inside, your dashboard acts like a specialized, encrypted email inbox. You will see sections for your inbox, sent items, and pending requests. Unlike personal email, each message thread is tied to an active case, an IRS notice, or a specific registration number.
File Attachments and Document Security
One of the most valuable features explained in Publication 6025 is uploading supporting documents. The system accepts standard document formats such as PDF, JPEG, and PNG. However, to maintain government cybersecurity, files containing macros, zip archives, or executable scripts are automatically rejected.
Conversation Threads and Response Times
Messages sent through the platform create an official, time-stamped paper trail. When an IRS representative responds to your message or requests additional proof, you receive an automated notification at your primary email address directing you to log in to read the secure message.
5. Practical Examples or Scenarios
Scenario 1: Resolving a Form 1040 Documentation Notice
Sarah receives an IRS notice asking for receipts to verify her charitable deduction. Instead of photocopying papers and mailing them to a service center, she logs into her IRS account. Following Publication 6025, she navigates to Secure Messaging, uploads PDF copies of her receipts, and submits them directly into her case file with instant electronic confirmation.
Scenario 2: Business Registration for Clean Energy Credits
A small manufacturing firm registers for clean energy credits and receives an inquiry from an IRS specialist regarding their facility documentation. The company accountant refers to Publication 6025 to locate the message thread under their Business Tax Account. The accountant uploads the facility proof and sends a response within minutes, preventing processing delays.
6. How This Publication Relates to Specific Forms
Publication 6025 does not replace any tax return, but it directly supports the filing and resolution of many common IRS forms:
- Form 1040 (U.S. Individual Income Tax Return): Used by individuals to provide missing schedules or substantiate deductions when queried by the IRS.
- Form 2848 (Power of Attorney and Declaration of Representative): Enables tax professionals to access Secure Messaging on behalf of their clients once authorization is recorded.
- Form 8821 (Tax Information Authorization): Allows designated third parties to view messages and documents without full legal representation authority.
- Form 990-T and Form 3800: Frequently paired with digital messaging when entities register for clean energy or elective payment credits and need to respond to pre-filing compliance checks.
7. Common Misunderstandings Clarified
Misunderstanding 1: Secure Messaging is Normal Email
Many taxpayers assume they can send standard emails to an IRS employee’s inbox. The IRS does not initiate or conduct case audits through unsecured public email. Secure Messaging is an internal, encrypted portal accessible only through verified IRS login systems.
Misunderstanding 2: You Can Message Any Agent at Any Time
Secure Messaging is not an open general-chat hotline. It is initiated when you have an active notice, an ongoing case assignment, or a registered account process that permits digital two-way communication.
Misunderstanding 3: You Can Upload Any File Without Limits
Taxpayers often attempt to upload large video files, password-locked spreadsheets, or compressed folders. Publication 6025 clarifies that encrypted files or unapproved formats will fail security screening and cannot be opened by agents.
8. Why This Publication Matters for Taxpayers
Understanding Publication 6025 saves taxpayers significant time, money, and anxiety. Sending documents through traditional mail can take weeks, during which deadlines may loom and penalties can accumulate. Secure Messaging provides instant proof of delivery.
In addition, using the secure portal drastically lowers your risk of becoming a victim of tax scams. Because all interactions occur behind multifactor authentication on IRS.gov, you can be certain you are communicating with real IRS personnel rather than a fraudster.
9. Frequently Asked Questions
Is there any cost to use IRS Secure Messaging?
No. IRS Secure Messaging is a free service provided by the federal government for individuals, businesses, and authorized representatives.
How do I know when the IRS has replied to my message?
The IRS system automatically sends a notification to your personal email address stating that a new communication is waiting. For privacy reasons, the notification itself will never contain tax numbers or sensitive details; you must log in to view the message.
What should I do if my file upload fails?
Check the file extension and size. Convert your documents into standard PDF or image files (such as JPG or PNG), remove any passwords, and make sure the file size does not exceed the platform limits listed in the guide.
Can my tax preparer message the IRS for me?
Yes, provided you have filed a valid Form 2848 or Form 8821 granting them digital account authority. Once approved, your preparer can use their own Tax Pro Account to review and reply to message threads.
10. Conclusion
IRS Publication 6025 serves as an essential roadmap for navigating the digital modern era of tax administration. By using the Secure Messaging system, taxpayers can handle inquiries quickly, maintain verifiable records, and bypass lengthy postal transit times.
