A TCC (Transmitter Control Code) is what lets you e-file information returns like 1099s with the IRS. The old FIRE system is being retired, so new applications now go through IRIS (Information Returns Intake System) only.
The IRS says a typical application takes about 45 business days. Apply well before your 1099 deadline.
Step 1: Gather your info
Your firm’s EIN, legal name, and addresses.
At least two Responsible Officials. One is enough for a sole proprietorship, S-corp, or single-member LLC.
At least two Contacts, with the same exception.
Up to two Authorized Delegates (optional).
For each person: SSN or ITIN, date of birth, citizenship, email, phone, and title.
Step 2: Apply through IRIS
Read IRS Publication 5903, the IRS’s step-by-step tutorial for the application.
Go to irs.gov/iristcc and sign in or create an account. Everyone listed on the application also needs an account.
Choose Individual on the organization page. Then start a New Application and select IRIS Application for TCC.
Fill in your firm information. Then pick your roles and how you’ll file: the web portal or A2A (system-to-system). Each role and filing method combination gets its own TCC.
Add your Responsible Officials and Contacts and review the summary.
Each Responsible Official signs with their 5-digit PIN and accepts the terms.
Step 3: Find your TCC once you’re approved
Once your application shows Completed, the TCC appears on the application summary page. You can use it right away, before the acceptance letter arrives in the mail.
Step 4: Enter it in Rentvine
Click your initials in the bottom left and select Settings.
Under Accounting, click Tax Reporting.
Enter your TCC in Transmitter Control Code.
Enter your Transmitter Name Control: up to 4 characters the IRS uses to match your business, usually the first four letters of your legal business name as the IRS has it on file.
Fill out the rest of the transmitter and contact fields, then click Save.
When you’re ready to file, go to the Tax Reporting page, select your payees, and click Actions › Download IRIS File(s). Upload that file to IRIS.
Frequently Asked Questions
Do I need a TCC if I’m only mailing paper 1099s?
No. Enter a placeholder such as 99999 in both TCC fields so your Tax Settings save. Your IRIS file won’t be accepted until you replace it with a real TCC.
Can I still use my old FIRE TCC?
The FIRE system is being retired, and new TCC applications go through IRIS only.
Does Rentvine apply for a TCC or file with the IRS for me?
No. You apply for your own TCC and upload your IRIS file yourself.
