What is IRS Publication 5945?
IRS Publication 5945, titled “Affordable Care Act (ACA) App for TCC Tutorial,” is a comprehensive guide released by the Internal Revenue Service to assist users in applying for a Transmitter Control Code (TCC) under the ACA. This 26-page document (Catalog Number 94735C) provides detailed, step-by-step instructions for completing, submitting, and modifying the ACA Application for TCC. It’s particularly valuable for tax professionals, employers, and software vendors involved in filing Forms 1094-B, 1095-B, 1094-C, and 1095-C electronically.
The publication was last revised in May 2024, ensuring it aligns with current IRS e-Services protocols. It’s part of the broader ACA Information Returns (AIR) program, which mandates electronic filing for those submitting 10 or more returns. By following this tutorial, you can avoid delays in processing, which typically takes up to 45 business days.
Key highlights include:
- Target Audience: Issuers (filing for their own company), Transmitters (handling multiple EINs), and Software Developers (creating compliant software).
- Why It’s Important: Without a TCC, you cannot participate in the AIR transmission program, risking non-compliance penalties.
- Accessibility: Available as a free PDF download from IRS.gov, making it easy to reference during the application process.
If you’re new to ACA e-filing, start by registering for IRS e-Services, as it’s a prerequisite for accessing the ACA Application for TCC.
The Purpose of the ACA Application for TCC
The core objective of the ACA Application for TCC is to obtain authorization for electronic filing of ACA-related information returns. This code acts as your digital key to the IRS’s AIR system, ensuring secure and compliant transmissions.
Eligible Roles and TCC Assignments
You can apply for one or more roles, each receiving a unique five-character alphanumeric TCC:
- Issuer: For transmitting returns solely for your own organization.
- Transmitter: For filing on behalf of your company and/or other entities (multiple EINs).
- Software Developer: For developing software that meets IRS specifications for origination or transmission.
Roles can overlap—for instance, a firm might serve as both a Transmitter and Software Developer—but each requires a separate TCC. The application collects firm details like EIN, legal name, addresses, and phone numbers, along with individual info for Responsible Officials (ROs), Authorized Delegates (ADs), and Contacts.
Overall Process Overview
- Preparation: All ROs, ADs, and Contacts must have active e-Services accounts.
- Completion: Fill out the application pages accurately.
- Submission: ROs sign using their e-Services PIN.
- Review and Approval: IRS processes the application (up to 45 days), assigning TCCs upon approval.
- Post-Approval: Receive TCCs online and via mail; use them for testing or live filings.
Important note: The IRS sends written confirmation of acceptance or rejection, and you must update software packages annually for new tax years.
