ACA Year-End Requirements for Small Employers: Who Must File in 2026 (Tennessee Guide)
ACA Year-End Requirements for Chattanooga Employers (2026 Guide)
For many employers, Affordable Care Act (ACA) reporting is one of the most confusing year-end compliance tasks.
Businesses that qualify under the ACA employer mandate must track employee eligibility, document health coverage offers, and file the correct IRS forms each year.
If you operate a business in Chattanooga or anywhere in Tennessee, understanding ACA reporting requirements can help you avoid penalties and ensure your payroll and HR systems remain compliant.
This guide explains the 2026 ACA year-end requirements, including who must file, which forms are required, and key compliance deadlines.
Who Must Comply With ACA Reporting?
ACA reporting primarily applies to Applicable Large Employers (ALEs).
An ALE is defined as a business that averaged 50 or more full-time employees or full-time equivalent employees during the previous calendar year.
Full-time employees are generally defined as employees who work 30 hours per week or 130 hours per month.
Businesses that meet this threshold must:
• Offer affordable health insurance to full-time employees and dependents • Track employee eligibility and coverage status • File annual ACA reports with the IRS
Even smaller employers may have reporting requirements if they sponsor self-insured health plans.
Key ACA Reporting Forms
ACA reporting is completed using a set of IRS forms that document employee health coverage.
Form 1095-C
This form reports:
• Which employees were offered health coverage • Whether the coverage met ACA affordability rules • The months coverage was offered or accepted
Employees receive a copy of this form for their personal tax records.
Form 1094-C
This form is the employer summary report submitted to the IRS.
It provides an overview of:
• total employee counts • coverage offers • employer compliance status
Employers sponsoring self-insured health plans may also need to complete Forms 1094-B and 1095-B depending on the coverage structure.
ACA Reporting Deadlines for 2026
ACA reporting follows a strict annual schedule.
For the 2025 coverage year reported in 2026, the key deadlines are:
March 2, 2026 Deadline to provide Form 1095-C to employees.
March 31, 2026 Deadline to electronically file Forms 1094-C and 1095-C with the IRS.
February 28, 2026 Paper filing deadline if submitting fewer than 10 forms (electronic filing is required for most employers).
Missing these deadlines can result in IRS penalties for each form that is late, incorrect, or not filed.
ACA Affordability Requirements
Employers must also ensure that the health coverage offered to employees meets ACA affordability standards.
For 2026 reporting, employer coverage must generally cost employees no more than approximately 9.96% of their household income for the lowest-cost self-only plan.
If coverage is considered unaffordable or fails to meet minimum value requirements, employers may face ACA employer shared responsibility penalties.
Common ACA Reporting Challenges
ACA reporting requires accurate employee tracking throughout the year.
Employers frequently run into issues such as:
• Miscalculating full-time employee counts • Missing variable-hour employee eligibility changes • Incorrect payroll or benefit data • Incomplete employee records • Late reporting filings
Even small data errors can create compliance problems during year-end reporting.
Preparing for ACA Reporting Before Year-End
The best time to prepare for ACA reporting is before the end of the year, not during filing season.
Employers should review:
• Employee hours and full-time status • health coverage eligibility tracking • benefit plan affordability calculations • employee demographic data • payroll and benefits system integrations
Using integrated payroll and HR systems helps reduce manual reporting work and improves data accuracy.

ACA Compliance for Growing Chattanooga Businesses
As companies grow, ACA compliance becomes more complex.
Businesses approaching the 50-employee threshold should review their workforce structure early to determine whether they will qualify as an Applicable Large Employer.
Proper planning allows businesses to implement payroll, HR, and reporting systems before ACA reporting deadlines arrive.
Some companies also combine payroll services with bookkeeping support to maintain organized financial and payroll records.
