The IRS has just introduced a significant shift in how international entities manage U.S. information returns. As of July 2026, the new Foreign Filer TCC Registration System is officially live, providing a dedicated pathway for non-U.S. businesses to maintain compliance. This launch arrives at a critical moment: the legacy FIRE (Filing Information Returns Electronically) system is entering its final stages, with a major application deadline set for July 21, 2026.
If you are a UK Limited Company or an international e-commerce seller operating in the U.S. market, these changes directly impact how you file Form 1042-S and various 1099 forms. Navigating these digital transitions is essential to avoid service interruptions and ensure your cross-border operations remain fully compliant with the latest IRS protocols.
The New Foreign Filer TCC Registration System (Publication 6170)
For years, international filers without a U.S. Taxpayer Identification Number (SSN or ITIN) faced hurdles when trying to obtain a Transmitter Control Code (TCC) for electronic filing. The newly launched Foreign Filer TCC Registration System, detailed in IRS Publication 6170, solves this by allowing certain foreign entities to register without a U.S. TIN.
This system is specifically designed for foreign filers whose authorized users do not have U.S. identification. Through this secure web-based portal, you can now:
- Register for a TCC GIIN: Obtain a specific Global Intermediary Identification Number (GIIN) associated with your transmitter registration.
- Request a TCC: Secure the code necessary to transmit data through the International Data Exchange System (IDES).
- Access IDES: Use your approved TCC GIIN and TCC to enroll in IDES, which is the required platform for transmitting Forms 1042-S and applicable 1099s for non-U.S. filers.
Important Note: If your authorized users do have a U.S. TIN (SSN or ITIN), you must not use this system. Instead, you are required to apply for a TCC through the IRIS (Information Returns Intake System) portal.
The FIRE System Retirement: July 21 Deadline
The IRS is moving away from the legacy FIRE system to modernize U.S. tax data processing. The transition is happening rapidly, and you must take note of the following critical dates:
- July 21, 2026: This is the final day the IRS will accept new FIRE TCC applications. If you do not have a FIRE TCC by this date, you will be unable to obtain one for the legacy system.
- December 31, 2026: The FIRE system will be decommissioned. While existing TCC holders can update their applications until this date, the system will become "read-only" shortly thereafter.
- Filing Season 2027: All electronic information returns must transition to IRIS or the IDES (for specific foreign filers).
Don’t wait for the deadline. If you currently rely on a FIRE TCC, it will not work in the new IRIS system. You must apply for an IRIS-specific TCC or follow the Foreign Filer registration path to ensure your 2027 filings are not delayed. Maintaining continuous compliance is the only way to protect your business from tax deadlines and penalties.
Business Tax Account Expanded Features (FS-2026-11)
Alongside these filing system updates, the IRS has expanded the Business Tax Account (BTA) platform. According to Fact Sheet FS-2026-11, released in July 2026, the BTA now offers several high-value self-service tools that simplify administrative tasks for international sellers:
- CP575 Notice Downloads: You can now download your official EIN verification notice (CP575) directly from the BTA. This is a vital document often requested by banks and payment processors to verify your U.S. tax status.
- Expanded Digital Notices: The IRS has added more notices to the online library, including refund notifications and extension approvals. This reduces the reliance on physical mail, which is often slow for UK-based businesses.
- Offer in Compromise (OIC) Payments: Eligible taxpayers can now submit OIC payments directly through the portal, integrating debt management into the digital dashboard.
By utilizing these tools, you can manage your ecommerce compliance abroad with greater visibility and less administrative friction.
Automatic Exemption from Penalty Program (FS-2026-12)
The IRS is also introducing a new "carrot" for compliant taxpayers. Fact Sheet FS-2026-12 outlines the Automatic Exemption from Penalty program. This initiative is designed to recognize and reward businesses that have a consistent history of timely filing and payment.
While full operational details are still emerging, the program aims to:
- Automatically waive certain penalties without requiring a manual request from the taxpayer.
- Focus on compliance history: Eligibility is tied to your track record of meeting U.S. tax obligations on time.
This makes tax compliance for e-commerce marketplaces even more rewarding. Staying organized and filing correctly now doesn’t just avoid fines, it can earn you a "safety net" for the future.
Practical Checklist for International Sellers
To prepare for these changes and the looming FIRE retirement, international businesses should follow this checklist:
- Audit Your TCC Status: Determine if your current filing code is for FIRE or IRIS. If it’s FIRE, plan your migration immediately.
- Verify User IDs: Check if your authorized users have U.S. TINs. If they don’t, review Publication 6170 to see if you qualify for the Foreign Filer TCC Registration System.
- Register for BTA: Set up your IRS Business Tax Account to access the new digital notice library and download your CP575 notice.
- Clean Up Compliance History: Ensure all past-due filings are settled to qualify for the new Automatic Exemption from Penalty program.
- Centralize Data: Maintain accurate bookkeeping to ensure your 1042 and 1099 data is ready for the new e-filing systems.
