IRS Application for TCC: FIRE, IRIS, and ACA AIR Systems

To get an IRS Transmitter Control Code, submit the IR Application for TCC online at irs.gov: choose your filing role, enter your business and personal identification details, and have each Responsible Official electronically sign the submission. Because the IRS takes up to 45 business days to process it, the agency recommends applying by November 1 of the year before your information returns are due.¹ A TCC is the five-character alphanumeric code the IRS uses to identify your business when you electronically transmit information returns like the 1099, 1098, 1042-S, 5498, and W-2G series.² Without it, you cannot access the IRS electronic submission systems.

Do You Need a TCC

Any business, fiduciary, or government agency that files 10 or more information returns in a calendar year must file them electronically. The threshold dropped from 250 to 10 for calendar years after 2021.³ The count is aggregated across all information return types, so a business issuing seven 1099-NECs and four 1099-MISCs is over the line. If you fall below 10, you can still apply and file electronically by choice.

One boundary worth clearing up: a TCC is not an EFIN. Tax professionals who e-file income tax returns like Forms 1040, 1120, or 990 use the IRS e-File system and need an Electronic Filing Identification Number. If your job is filing information returns that report payments and financial transactions, you need a TCC. If your job is filing someone’s tax return, you need an EFIN.

Which TCC to Apply For

The IRS runs separate electronic filing systems for different categories of information returns, and each system needs its own TCC. Pick the right one before you start.

FIRE System TCC

The Filing Information Returns Electronically (FIRE) system covers the broadest range of forms: the 1097, 1098, 1099, 3921, 3922, 5498, W-2G, 1042-S, 8027, and 8955-SSA series.² A FIRE TCC always begins with a number. You can select multiple form types on one application, so a single FIRE TCC can cover your 1099s and your 1042-S filings together.

IRIS TCC

The Information Returns Intake System (IRIS) is a newer, free, browser-based portal that accepts Forms 1099 for tax year 2022 and later.⁴ It suits smaller filers who want to key returns in directly rather than upload bulk files. An IRIS TCC begins with the letter “D.”⁵ If you only file 1099s, IRIS is often the simpler path.

ACA AIR System TCC

If you file Affordable Care Act returns (Forms 1094-B, 1095-B, 1094-C, or 1095-C), you need a separate TCC for the ACA Information Returns (AIR) system. Each role you select on the ACA application (software developer, transmitter, or issuer) generates its own TCC.⁶

Issuer or Transmitter

The application asks whether you are an “issuer” or a “transmitter.” An issuer transmits information returns only for itself, meaning the entity listed on the application, no matter how many locations it operates. A transmitter is a third-party business that files returns on behalf of other companies, either alongside or instead of its own.²

A payroll service, accounting firm, or software provider handling client 1099s applies as a transmitter. A single company filing its own 1099s for the contractors it paid applies as an issuer. Picking the wrong role can delay processing, so settle this before you log in.

What to Gather Before You Start

The IRS validates every field against its own records. Small mismatches, even a slightly different business name format, cause delays. Pull everything together first.

An IRS Account for Every Person Listed

Every Responsible Official, Authorized Delegate, and Contact needs an IRS account verified through ID.me.⁷ ID.me verification involves uploading a government-issued photo ID and completing either a video selfie or a live video call. If several people need accounts, start weeks early; this is often the biggest bottleneck.

Entity Information

Have your legal business name exactly as it appears in IRS records, your Employer Identification Number, and both your physical and mailing addresses. If you recently changed your name or address with the IRS, confirm those updates went through before applying.

Responsible Officials

A Responsible Official (RO) is the person authorized to oversee the entity’s compliance with IRS electronic filing rules. Most business types must list at least two ROs. Sole proprietors, S-corporations, and single-member LLCs need only one.² For each RO, you need full legal name, title, Social Security Number or ITIN, and date of birth. Each RO also creates a five-digit PIN and electronically signs the application.

Contacts

You must also list at least two Contacts, the people authorized to use the TCC for filing and to answer IRS inquiries. The same exception applies: sole proprietors, S-corporations, and single-member LLCs need only one. You can list up to 250 Contacts.² For each, you need name, phone number, and email. Every Contact needs their own ID.me-verified IRS account to access the filing system later.

Form Types

Know exactly which information returns you will submit. The application asks you to select only the forms you know you will file electronically. You can update the application later to add form types, but naming them correctly the first time saves a step.

Walking Through the Application

Once everyone has an ID.me-verified IRS account, a Responsible Official logs in to the right portal. For a FIRE TCC, that is the IR Application for TCC tool. For IRIS, it is the IRIS Application for TCC. Both authenticate through ID.me.

Select “New TCC Application” to begin. The first screens collect legal entity information: EIN, official business name, and addresses. Enter these exactly as they appear in IRS records. The system then walks you through each Responsible Official (full name, title, SSN, date of birth) and validates that information against the person’s existing Secure Access registration. If what you type does not match what the person registered under, you will hit an error.

Contact screens come next. After that, you pick the specific forms your entity will file, such as Form 1099-NEC or Form 1042-S. The final screen is a review page where every RO must electronically sign using their five-digit PIN.⁸ If your organization has two ROs, both must sign before the application can be submitted.

Submission produces a confirmation. That confirmation is not your TCC. The IRS still has to review and approve the application before assigning the code.

How Long It Takes

The IRS takes up to 45 business days to process a TCC application and may request additional documentation if anything does not match its records.¹ Those are business days, so the window can stretch to roughly nine calendar weeks.

The agency recommends submitting by November 1 of the year before your information returns are due.¹ For most 1099s due in early 2027, that means applying by November 1, 2026. Waiting until January when your returns are due at the end of the month is how filers end up paying penalties.

Once approved, your TCC appears in the IR Application for TCC portal. The IRS also sends an acceptance letter by mail, but you can start filing as soon as the code shows in your online account.

After You Have the Code

First-time FIRE filers are strongly encouraged (though not generally required) to submit a test file before production filing. The test confirms your software formats data correctly under the Publication 1220 specifications. The FIRE production and test systems are separate and need separate accounts.⁹

Keep the TCC active. Update Responsible Official and Contact information through the portal whenever someone leaves or changes roles; outdated details cause problems when the IRS tries to reach you or when staff try to log in. And use the TCC. The IRS deletes any TCC that has not been used to electronically file for three consecutive years, and a deleted TCC cannot be reactivated. You would submit a new application and wait through the full processing period again.¹

What Skipping Electronic Filing Costs

If you are required to file electronically and don’t, whether because you never got a TCC, filed on paper, or missed the deadline, the IRS treats each late or incorrect return as a separate violation. For returns due in 2026, the penalties are:¹⁰

Filed up to 30 days late: $60 per return
Filed 31 days late through August 1: $130 per return
Filed after August 1 or not at all: $340 per return
Intentional disregard: $680 per return with no maximum cap

These add up quickly. A business filing 500 late 1099s after August 1 faces $170,000 in penalties. Getting the IR Application for TCC in months before filing season is the cheapest insurance against numbers like that.
