Understanding Authoritative vs Non-Authoritative 1094-C Transmittals

Introduction: Why the Authoritative Designation Matters

When filing ACA forms with the IRS, one of the most misunderstood aspects of Form 1094-C is the distinction between authoritative and non-authoritative transmittals. This seemingly simple checkbox on Line 12 of Form 1094-C has significant implications for how the IRS processes your ACA submission, calculates potential penalties, and maintains your compliance records. Understanding the difference between authoritative and non-authoritative 1094-C transmittals is essential for any Applicable Large Employer (ALE) navigating ACA reporting requirements.

The stakes for getting this designation wrong are considerable. If an employer files multiple Forms 1094-C and incorrectly marks more than one as authoritative, the IRS may reject the filing or use incorrect aggregate data when calculating potential employer shared responsibility penalties. Conversely, if an employer fails to designate any Form 1094-C as authoritative, the IRS will lack the official aggregate data it needs to properly process the submission, potentially triggering error notices and delays.

This comprehensive guide explains the 1094-C authoritative designation in detail, covering when to use authoritative versus non-authoritative transmittals, how controlled groups should handle multiple filings, best practices for batch submissions, and common mistakes that lead to IRS rejections. Whether you are an HR professional managing ACA compliance internally, an accountant filing on behalf of multiple clients, or a service provider handling thousands of forms, this guide provides the clarity you need.

What is an Authoritative 1094-C Transmittal?

The Official Definition and Purpose

An authoritative 1094-C transmittal is the single Form 1094-C that serves as the official record for an ALE member's aggregate ACA data and compliance certifications. Line 12 of Form 1094-C asks: "Is this the Authoritative Transmittal for this ALE Member?" When you check "Yes" on this line, you are designating that particular Form 1094-C as the authoritative transmittal that the IRS should use as the definitive source of organizational-level information for your ACA filing.

The authoritative transmittal serves several critical functions. First, it provides the IRS with the aggregate data needed to evaluate employer compliance, including monthly full-time employee counts, total employee counts, and indicators of whether minimum essential coverage was offered to at least 95% of full-time employees. Second, it contains the official certifications about the employer's compliance status, such as whether the employer used the Qualifying Offer Method or meets the 98% Offer threshold. Third, for employers in controlled groups, it reports the complete list of other ALE members in the aggregated group.

The IRS uses the data from the 1094-C authoritative transmittal to determine whether an employer may be subject to Penalty A or Penalty B under the employer shared responsibility provisions. If the authoritative transmittal indicates that the employer did not offer coverage to at least 95% of full-time employees, and at least one employee received a premium tax credit for Marketplace coverage, the IRS may assess Penalty A. The monthly full-time employee counts reported on the authoritative transmittal directly influence penalty calculations.

Key Characteristics of an Authoritative Transmittal

An authoritative Form 1094-C has several distinguishing characteristics that set it apart from non-authoritative transmittals:

Characteristic Authoritative 1094-C Non-Authoritative 1094-C
Line 12 Checkbox Checked "Yes" Left blank or "No"
Parts II and III Must be completed fully Can be left blank
Part IV (Controlled Groups) Must list all other ALE members Can be left blank
Total 1095-C Count (Line 18) Reports total for ALL batches Reports only attached batch
IRS Usage Official record for penalties Supplemental only
Quantity per ALE Member Exactly one per tax year As many as needed

The most important rule to remember: each ALE member can have only one authoritative Form 1094-C per tax year. This is true regardless of how many Forms 1095-C the employer files or how many batches those forms are submitted in. The one authoritative transmittal serves as the master record, while all other Forms 1094-C are non-authoritative supplements.

What is a Non-Authoritative 1094-C Transmittal?

Purpose and Appropriate Use Cases

A non-authoritative 1094-C transmittal is a Form 1094-C that accompanies a batch of Forms 1095-C but does not serve as the official record for the ALE member's aggregate data. Non-authoritative transmittals are used when an employer needs to submit Forms 1095-C in multiple batches or when additional Forms 1094-C are needed for technical reasons, such as listing more than 30 controlled group members in Part IV.

Non-authoritative transmittals are essentially cover sheets that allow the IRS to process batches of Forms 1095-C. They identify which ALE member the forms belong to (through Part I) but do not provide the authoritative aggregate data that the IRS uses for penalty determinations. The IRS will look to the authoritative transmittal for that information.

Common scenarios requiring non-authoritative 1094-C transmittals include:

  • Batch filing for large employers: An employer with 5,000 employees may submit Forms 1095-C in five batches of 1,000. The first batch includes the authoritative 1094-C; the remaining four batches each include a non-authoritative 1094-C.
  • Multiple controlled group members in Part IV: Part IV has space for only 30 other ALE members. If a controlled group has 50 members, the employer files the authoritative 1094-C listing 30 members, then files non-authoritative Forms 1094-C to list the remaining 20.
  • Supplemental filings: If an employer discovers after filing that some Forms 1095-C were omitted, the supplemental submission uses a non-authoritative 1094-C as the transmittal.
  • Corrections: When filing corrected Forms 1095-C, the accompanying Form 1094-C is typically non-authoritative (unless the authoritative transmittal itself needs correction).

What Non-Authoritative Transmittals Do Not Contain

When filing a non-authoritative Form 1094-C, you generally only need to complete Part I (ALE Member Information). Parts II, III, and IV can be left blank because the IRS will obtain that information from the authoritative transmittal. However, there are some nuances:

  • Part I: Always complete this section fully, including employer name, EIN, address, and contact information
  • Line 11: Enter the count of Forms 1095-C attached to this specific transmittal (not the total for all batches)
  • Line 12: Leave blank or check "No" to indicate this is not the authoritative transmittal
  • Parts II and III: Can be left blank for non-authoritative transmittals
  • Part IV: Only complete if this non-authoritative transmittal is being used to list additional controlled group members

The key distinction is that the IRS will only look at one Form 1094-C for the authoritative aggregate data. All other Forms 1094-C serve purely as transmittals to accompany batches of Forms 1095-C.

When to Use Authoritative vs Non-Authoritative 1094-C

Single Transmittal Filers

The simplest scenario is when an employer submits all Forms 1095-C in a single filing. In this case, the employer files exactly one Form 1094-C, and it must be marked as the authoritative transmittal. This is the most common situation for small to mid-sized ALEs.

Example: ABC Company is an ALE with 75 full-time employees. They file 75 Forms 1095-C with a single Form 1094-C. On Line 12 of the Form 1094-C, they check "Yes" to indicate this is the authoritative transmittal. They complete all sections of Form 1094-C, including Parts II, III, and IV (if part of a controlled group).

For single transmittal filers, the process is straightforward:

  1. Prepare all Forms 1095-C for all full-time employees
  2. Prepare one Form 1094-C with complete information in all parts
  3. Check "Yes" on Line 12 (authoritative transmittal)
  4. Enter the total count of Forms 1095-C on Line 11
  5. Submit all forms together

Multiple Batch Filers

Large employers often need to submit Forms 1095-C in multiple batches due to system limitations, timing considerations, or organizational structure. When filing multiple batches, the 1094-C authoritative designation becomes critical. Only one Form 1094-C should be marked as authoritative, regardless of how many batches are submitted.

Example: XYZ Corporation has 3,000 full-time employees. They decide to submit their Forms 1095-C in three batches of 1,000 forms each. The filing structure would be:

Batch Forms 1095-C Form 1094-C Type Line 11 Count Line 18 Count
Batch 1 1,000 Authoritative 1,000 3,000 (total)
Batch 2 1,000 Non-Authoritative 1,000 N/A
Batch 3 1,000 Non-Authoritative 1,000 N/A

Notice that the authoritative Form 1094-C reports the total count of all Forms 1095-C that will be filed (3,000 on Line 18), while non-authoritative Forms 1094-C only report the count for their specific batch (1,000 on Line 11 each). This allows the IRS to verify that all expected forms have been received across all batches.

Controlled Group Considerations

When an ALE is part of a controlled group or affiliated service group, the authoritative vs non-authoritative 1094-C designation requires careful planning. Each member of the controlled group that is an ALE must file its own Form 1094-C and Forms 1095-C. This means multiple authoritative Forms 1094-C will exist within the controlled group—one per ALE member.

Example: A parent company owns three subsidiaries: Sub A (200 employees), Sub B (150 employees), and Sub C (100 employees). Each subsidiary is an ALE member. The filing structure would be:

  • Sub A: Files one authoritative Form 1094-C + 200 Forms 1095-C
  • Sub B: Files one authoritative Form 1094-C + 150 Forms 1095-C
  • Sub C: Files one authoritative Form 1094-C + 100 Forms 1095-C

Each subsidiary's authoritative Form 1094-C must list the other two subsidiaries in Part IV. The controlled group relationship requires this cross-referencing so the IRS can verify that all related entities are properly reporting.

Importantly, if any of these subsidiaries filed in multiple batches, they would have one authoritative 1094-C and potentially multiple non-authoritative ones—but never more than one authoritative transmittal per EIN per tax year.

Line 12 of Form 1094-C: Completing the Authoritative Checkbox

Understanding Line 12

Line 12 of Form 1094-C reads: "Is this the Authoritative Transmittal for this ALE Member? If 'Yes,' check the box and complete Parts II, III, and IV, if applicable." This is a yes/no checkbox that determines whether the IRS treats this Form 1094-C as the official aggregate record for the employer.

The instructions for Line 12 are specific: check the box only if this is the authoritative transmittal. If you are filing multiple Forms 1094-C and this is not the authoritative one, leave the box unchecked. The absence of a checkmark tells the IRS that this is a non-authoritative transmittal and that the authoritative data exists on a different Form 1094-C.

What Happens When You Check "Yes" on Line 12

When you check "Yes" on Line 12, you are making several important declarations:

  • This is the official record: The IRS will use this Form 1094-C as the definitive source of your aggregate data
  • Parts II and III contain accurate data: Your monthly employee counts, coverage indicators, and certifications are complete and accurate
  • Part IV is complete (if applicable): If you are part of a controlled group, all other ALE members are listed
  • Line 18 reflects total forms: The count on Line 18 includes all Forms 1095-C you will file for this tax year, even if submitted in multiple batches

The certifications made on an authoritative Form 1094-C are legally binding. By signing the form (or authorizing electronic submission), the responsible person certifies under penalties of perjury that the information is true, correct, and complete. Incorrect authoritative data can lead to IRS Letter 226-J penalty assessments.

Common Line 12 Errors

Several common errors occur with Line 12 that can cause filing problems:

  • Multiple authoritative transmittals: Marking more than one Form 1094-C as authoritative for the same EIN in the same tax year. The IRS may reject all but the first or use inconsistent data for penalty calculations.
  • No authoritative transmittal: Failing to mark any Form 1094-C as authoritative. The IRS will lack the aggregate data needed to process the filing properly.
  • Incomplete authoritative transmittal: Checking "Yes" on Line 12 but leaving Parts II, III, or IV blank. This creates validation errors that may cause rejection.
  • Wrong total on Line 18: On the authoritative transmittal, Line 18 should reflect the total Forms 1095-C filed across all batches, not just the forms attached to this particular transmittal.

Parts II, III, and IV: Authoritative Transmittal Requirements

Part II: ALE Member Information and Certifications

Part II of an 1094-C authoritative transmittal contains important certifications about the employer's compliance status. This section includes checkboxes for the Qualifying Offer Method, Section 4980H Transition Relief (historical), and the 98% Offer Method certification.

Key Part II elements include:

  • Line 19 - Qualifying Offer Method: Check if you made a "qualifying offer" of affordable, minimum value coverage to all full-time employees. This allows simplified Form 1095-C reporting.
  • Line 22, Box A: Qualifying Offer Method certification
  • Line 22, Box D: 98% Offer Method—certify that you offered coverage to at least 98% of employees for whom you filed Forms 1095-C

These certifications directly affect potential penalty exposure. For example, checking Box D (98% Offer Method) indicates you offered coverage broadly, which relates to Penalty A vs Penalty B exposure.

Part III: Monthly Workforce Data

Part III is where the authoritative transmittal reports monthly aggregate data about the workforce. This data is essential for IRS penalty calculations and must be accurate.

Column Data Reported Importance
(a) MEC Offer Whether minimum essential coverage was offered to 95%+ of FT employees Determines Penalty A exposure
(b) FT Employee Count Number of full-time employees each month Used in penalty calculations
(c) Total Employee Count Total employees (FT + PT) each month Used for FTE calculations
(d) Aggregated Group Whether part of an aggregated ALE group Identifies controlled group membership
(e) Transition Relief Section 4980H relief indicators Historical (rarely applicable now)

The full-time employee counts in Column (b) are particularly critical. These numbers directly influence penalty calculations if the employer faces employer shared responsibility penalties. The penalty amount is calculated per full-time employee (minus 30 for Penalty A), so accurate counts are essential.

Part IV: Controlled Group Reporting

Part IV of an authoritative Form 1094-C lists all other ALE members in the controlled group or affiliated service group. This section is only completed when the employer is part of such a group. Part IV has space for up to 30 other ALE members. If more space is needed, additional Forms 1094-C (non-authoritative) are filed solely to list the remaining members.

Information required for each controlled group member:

  • Name: Legal name of the other ALE member
  • EIN: Employer Identification Number of the other ALE member

The controlled group reporting in Part IV enables the IRS to verify that all related entities are properly filing and to aggregate employees for purposes of determining ALE status. If one member of a controlled group fails to file, the IRS can identify the missing entity through the Part IV listings on other members' Forms 1094-C.

Step-by-Step Guide: Filing with Authoritative and Non-Authoritative Transmittals

Step 1: Determine Your Filing Structure

Before preparing any forms, determine how many transmittals you will need:

  • Single batch: One authoritative Form 1094-C only
  • Multiple batches: One authoritative Form 1094-C + non-authoritative Forms 1094-C for each additional batch
  • Controlled group with 30+ members: One authoritative Form 1094-C + additional non-authoritative forms for Part IV overflow

Step 2: Prepare the Authoritative Form 1094-C

The authoritative transmittal requires complete information:

  1. Complete Part I with accurate employer identification
  2. Enter the count of Forms 1095-C attached to this transmittal on Line 11
  3. Check "Yes" on Line 12 to designate as authoritative
  4. Complete Part II certifications accurately
  5. Complete Part III with monthly workforce data for all 12 months
  6. Complete Part IV listing all other ALE members (if applicable)
  7. Enter the total count of all Forms 1095-C you will file (all batches) on Line 18

Step 3: Prepare Non-Authoritative Forms 1094-C (If Needed)

For each additional batch or Part IV overflow:

  1. Complete Part I with accurate employer identification
  2. Enter the count of Forms 1095-C attached to this specific batch on Line 11
  3. Leave Line 12 blank or check "No"
  4. Leave Parts II and III blank (unless your software requires completion)
  5. Only complete Part IV if this form is used for additional controlled group member listings

Step 4: Submit in Proper Sequence

While there is no required submission order, best practices suggest:

  • Submit the authoritative Form 1094-C with the first batch
  • Submit non-authoritative transmittals with subsequent batches
  • Maintain records of all batch submissions and receipt confirmations

Step 5: Verify Receipt and Acceptance

After submission, verify that all transmittals were accepted:

  • Check filing status through the IRS AIR system or your software provider
  • Confirm that the authoritative transmittal was accepted
  • Verify total Forms 1095-C accepted matches your Line 18 count
  • Address any rejection errors promptly

Common Mistakes and How to Avoid Them

Mistake 1: Multiple Authoritative Transmittals

One of the most common errors is marking multiple Forms 1094-C as authoritative for the same ALE member in the same tax year. This typically happens when:

  • Different departments or locations file independently without coordination
  • A service provider and the employer both file without communication
  • Corrections are filed with the authoritative box checked when it should not be

How to avoid: Designate a single person or team responsible for coordinating all ACA filings. Ensure clear communication about which filing contains the authoritative transmittal. Use ACA software that prevents multiple authoritative designations.

Mistake 2: No Authoritative Transmittal Filed

Some employers file multiple batches but fail to mark any Form 1094-C as authoritative. The IRS cannot properly process the submission without aggregate data.

How to avoid: Always verify that exactly one Form 1094-C has Line 12 checked "Yes" before completing your filing. Review all transmittals as part of final quality control.

Mistake 3: Incomplete Authoritative Transmittal

Checking "Yes" on Line 12 but failing to complete Parts II, III, or IV creates validation errors. The IRS requires complete data on the authoritative transmittal.

How to avoid: Use the IRS instructions or ACA software that validates completeness before allowing submission. Double-check all monthly data in Part III.

Mistake 4: Incorrect Form Counts

Errors in Line 11 (attached forms) or Line 18 (total forms) can cause the IRS to flag the filing as incomplete or inconsistent.

How to avoid:

  • Line 11 should match the actual Forms 1095-C attached to that specific transmittal
  • Line 18 on the authoritative transmittal should equal the sum of all Line 11 counts across all transmittals
  • Use software that automatically calculates these counts

Mistake 5: Controlled Group Confusion

Employers sometimes misunderstand that each ALE member in a controlled group needs its own authoritative Form 1094-C. They may incorrectly try to file one authoritative transmittal for the entire group.

How to avoid: Remember that each separate EIN needs its own authoritative Form 1094-C. The controlled group relationship is reported in Part IV, but each member files independently with their own authoritative transmittal.

Correcting Authoritative Transmittal Errors

When the Authoritative Transmittal Needs Correction

If you discover errors on your authoritative Form 1094-C after filing, you may need to file a corrected version. Common reasons for correcting an authoritative transmittal include:

  • Incorrect monthly employee counts: Part III data was wrong
  • Wrong certifications: Checked or failed to check a certification incorrectly
  • Missing controlled group members: Part IV was incomplete
  • Incorrect total form count: Line 18 did not reflect actual filings

How to File a Corrected Authoritative 1094-C

To correct an authoritative Form 1094-C:

  1. Prepare a new Form 1094-C with the corrected information
  2. Check the "Corrected" box at the top of the form
  3. Check "Yes" on Line 12 (this is still the authoritative transmittal—just corrected)
  4. Complete all sections with accurate data
  5. Submit through the IRS AIR system or your transmitter

Note that a corrected authoritative Form 1094-C replaces the original. The IRS will use the corrected version as the official record. You do not need to re-file all Forms 1095-C unless those also contain errors.

Correcting from Non-Authoritative to Authoritative

If you accidentally filed without any authoritative transmittal, you can file a corrected Form 1094-C with the authoritative designation. Mark it as corrected and check "Yes" on Line 12. Complete all required sections. This corrected form will become the authoritative record.

IRS Penalties and the Authoritative Transmittal Connection

Information Return Penalties

Errors on Form 1094-C, including authoritative transmittal issues, can trigger information return penalties. These penalties apply per form and vary based on when corrections are made:

Correction Timing Penalty Per Form (2025) Maximum Penalty
Within 30 days of deadline $60 $630,500
By August 1 $130 $1,891,500
After August 1 / Not corrected $330 $3,783,000
Intentional disregard $660+ (no cap) Unlimited

Employer Shared Responsibility Penalty Connection

Beyond information return penalties, the authoritative Form 1094-C directly influences employer shared responsibility penalty (ESRP) assessments. The IRS uses the data from the authoritative transmittal to determine:

  • Whether the employer offered coverage to 95% of full-time employees: Based on Part III Column (a)
  • The number of full-time employees: From Part III Column (b), used in penalty calculations
  • Controlled group relationships: From Part IV, affecting penalty allocation

Inaccurate data on the authoritative transmittal can result in incorrect IRS Letter 226-J penalty proposals. If you receive a penalty notice based on incorrect authoritative data, you must respond with documentation showing the correct information.

Filing Deadlines for Form 1094-C

Federal IRS Deadline

Form 1094-C, whether authoritative or non-authoritative, must be filed with the IRS by the same deadline as Forms 1095-C. For tax year 2025, the filing deadline is:

  • Electronic filing: March 31, 2026
  • Paper filing: February 28, 2026 (only for filers with fewer than 10 forms)

Since virtually all ALEs have more than 10 full-time employees, electronic filing is mandatory, making March 31, 2026 the effective deadline for most employers.

Extensions

Employers can request an automatic 30-day extension by filing Form 8809 before the deadline. This extends the IRS filing deadline to April 30. The extension applies to the entire submission, including both authoritative and non-authoritative transmittals.

For complete deadline information, see the 2026 Filing Deadlines guide.

State Filing Considerations

Several states require separate ACA reporting submissions. These states typically follow similar rules regarding transmittal forms, though the specific requirements may vary:

Frequently Asked Questions About Authoritative vs Non-Authoritative 1094-C

What is the difference between authoritative and non-authoritative 1094-C?

An authoritative Form 1094-C is the single official transmittal that contains complete aggregate data for an ALE member, including monthly workforce counts, compliance certifications, and controlled group information. A non-authoritative Form 1094-C is a supplemental transmittal used when filing in multiple batches or listing additional controlled group members. Each ALE member can have only one authoritative 1094-C per tax year, but may have multiple non-authoritative ones.

How many authoritative Forms 1094-C can I file?

Each ALE member (each unique EIN) can file exactly one authoritative Form 1094-C per tax year. This is true regardless of how many batches you submit or how many Forms 1095-C you file. If you are part of a controlled group, each member files its own authoritative 1094-C for its own employees.

What happens if I mark two Forms 1094-C as authoritative?

Filing multiple authoritative Forms 1094-C for the same EIN in the same tax year may cause the IRS to reject one or both submissions, or to use inconsistent data for processing. If this occurs, you should file a corrected Form 1094-C to clarify which one is authoritative. The IRS may contact you for clarification.

Do I need to complete Parts II, III, and IV on non-authoritative transmittals?

No. Non-authoritative Forms 1094-C only require Part I (employer identification) to be completed. The exception is Part IV, which should be completed if the non-authoritative transmittal is being used to list additional controlled group members that did not fit on the authoritative transmittal.

What goes on Line 18 of the authoritative 1094-C?

Line 18 of the authoritative Form 1094-C should contain the total number of Forms 1095-C you will file for the tax year across all batches, not just the forms attached to this particular transmittal. This allows the IRS to verify that all expected forms have been received.

Can I file a non-authoritative 1094-C first and the authoritative one later?

Yes, there is no required order for submitting authoritative and non-authoritative transmittals. However, best practice is to submit the authoritative transmittal with the first batch to ensure the IRS has the aggregate data as early as possible.

How do controlled groups handle authoritative transmittals?

Each ALE member in a controlled group files its own authoritative Form 1094-C for its own employees. The controlled group relationship is reported in Part IV, where each member lists all other ALE members in the group. This means a controlled group with five ALE members will have five authoritative Forms 1094-C total (one per member).

What if I need to correct my authoritative 1094-C?

File a corrected Form 1094-C by checking the "Corrected" box at the top of the form. The corrected version should still have Line 12 checked "Yes" (it remains the authoritative transmittal—just corrected). Include all corrected information in Parts I through IV. The corrected form replaces the original.

Does the authoritative designation affect penalties?

Yes. The IRS uses data from the authoritative Form 1094-C to calculate potential employer shared responsibility penalties. The monthly full-time employee counts and coverage offer indicators on the authoritative transmittal directly influence whether and how much penalty may be assessed. Incorrect authoritative data can lead to incorrect penalty notices.

What if none of my Forms 1094-C is marked authoritative?

The IRS will lack the aggregate data needed to process your submission properly. You should file a corrected Form 1094-C with Line 12 checked "Yes" and complete all required sections. Until the authoritative transmittal is received, your filing may be considered incomplete.

Can software help manage authoritative vs non-authoritative transmittals?

Yes. Quality ACA reporting software like BoomTax automatically manages authoritative and non-authoritative designations, prevents multiple authoritative filings, calculates correct form counts, and validates data completeness before submission. This significantly reduces the risk of transmittal-related errors.

Is the authoritative transmittal different for Form 1094-B?

Form 1094-B (used with Form 1095-B for insurers and small self-funded employers) does not have the same authoritative transmittal concept. The distinction between authoritative and non-authoritative applies specifically to Form 1094-C used by Applicable Large Employers.

Conclusion: Mastering the 1094-C Authoritative Transmittal

Understanding the difference between authoritative and non-authoritative 1094-C transmittals is essential for accurate ACA reporting. The authoritative transmittal serves as the IRS's official record of your organization's aggregate compliance data, while non-authoritative transmittals facilitate batch filing and controlled group reporting. Getting this designation right ensures proper IRS processing and accurate penalty determinations.

Key takeaways:

  • One authoritative per ALE member: Each EIN can have only one authoritative Form 1094-C per tax year
  • Complete data required: The authoritative transmittal must have complete Parts II, III, and IV
  • Non-authoritative for batches: Use non-authoritative transmittals for additional batches or Part IV overflow
  • Controlled groups: Each ALE member files its own authoritative 1094-C; the group relationship is in Part IV
  • Line 12: Check "Yes" only on the authoritative transmittal; leave blank on non-authoritative ones
  • Line 18 total: The authoritative transmittal reports total Forms 1095-C across all batches
  • Corrections possible: You can file a corrected authoritative 1094-C if errors are discovered
  • Penalty implications: The IRS uses authoritative data for employer shared responsibility penalty calculations

By following the guidance in this article and using reliable ACA reporting software, employers can confidently navigate 1094-C authoritative transmittal requirements and maintain full ACA compliance.
