What Is an Applicable Large Employer (ALE)?

Last Updated: September 2026

An applicable large employer (ALE) is an employer that averaged at least 50 full-time employees, including full-time equivalent employees (FTEs), during the prior calendar year. ALEs are subject to the Affordable Care Act (ACA) employer mandate and must report health coverage offers to the IRS each year on Forms 1094-C and 1095-C.

ALE status is the starting point for ACA compliance. It decides whether the employer mandate applies to you, whether you owe annual IRS reporting, and whether you could face employer shared responsibility penalties. And because it's recalculated every year, a business that wasn't an ALE last year can become one this year.

The calculation looks simple, but it's easy to get wrong. Common mistakes include counting only full-time headcount, leaving out part-time hours, and looking at a single company when the IRS looks at the whole ownership group. This guide walks through who counts, how to calculate ALE status step by step, how aggregated groups work, and what changes once you're an ALE.

Key Takeaways

• An ALE averaged at least 50 full-time employees, including full-time equivalents, during the prior calendar year.
• Full-time means an average of 30 hours per week or 130 hours per month. Part-time hours count toward the threshold through the FTE calculation.
• Related companies combine their workforces, and each company in the group is an ALE member.
• ALEs must make an offer of healthcare coverage to at least 95% of ACA full-time employees (work an average of 30 hours per week). 
• The offer of coverage must be affordable, provide minimal essential coverage (MEC), and minimum value (MV). 
• ALEs must file 1094-C and 1095-C forms with the IRS every year.

What Is An Applicable Large Employer?

ALE stands for applicable large employer, a term defined in Section 4980H of the Internal Revenue Code. Under the IRS definition, an employer is an ALE for the current calendar year if it averaged at least 50 full-time employees, including FTEs, during the prior calendar year.

The rules apply to for-profit businesses, nonprofits, and government employers alike. Two ACA provisions apply only to ALEs:

• • The employer shared responsibility provisions, often called the employer mandate, which require an ALE to offer healthcare coverage that is affordable and meets the MEC and MV requirements. 
• The employer information reporting provisions under Section 6056, which require ALEs to file Forms 1094-C and 1095-C with the IRS and furnish Forms 1095-C to full-time employees.

The 50 FTE threshold and the penalty math aren't the same thing. Part-time hours count toward ALE status, but employer mandate penalties are calculated using full-time employees only. The ALE threshold is one of several ACA reporting terms every employer should know, and it's the one that decides whether the rest apply to you.

What Counts Toward ALE Status?

Determining ALE status starts with classifying your workforce correctly. The IRS counts more than your full-time headcount, and some workers don't count at all.

Full-Time Employees

Under the ACA, a full-time employee averages at least 30 hours of service per week, or 130 hours of service in a calendar month. Hours of service include hours worked plus hours of paid leave, such as vacation, holidays, and sick time.

This may not match your company's own definition of full-time for benefits eligibility or PTO. For ACA purposes, the 30-hour standard is the one that counts. For example, if a restaurant has 80 employees and 45 of them average at least 30 hours per week, those 45 employees are full-time employees for the ALE calculation.

Employees whose schedules change week to week take extra care, since their status can shift over time. Tracking variable hour employees consistently helps keep your monthly counts accurate.

Full-Time Equivalent Employees (FTEs)

Full-time equivalent employees (FTEs) convert part-time hours into a headcount used only to determine ALE status. To calculate FTEs for a month, add the hours of service for every employee who wasn't full-time that month, counting no more than 120 hours per employee, then divide the total by 120.

Part-time employees count toward the 50-employee threshold, but ALEs aren't required to offer them health coverage. The offer requirement applies to full-time employees. Keep in mind that the ACA's 120-hour FTE method is different from the 40-hour FTE formula many businesses use for budgeting and staffing.

Seasonal Workers and the 120-Day Exception

Seasonal workers count toward ALE status, but the seasonal worker exception can keep a business with a short-term hiring spike from becoming an ALE. Under the exception, an employer isn't an ALE if both of these are true:

• Its workforce exceeded 50 full-time employees (including FTEs) for 120 days or fewer, or four calendar months or fewer, during the prior year.
• The employees in excess of 50 during that period were seasonal workers.

For example, an agricultural operation with 40 full-time employees for most of the year brings on 110 seasonal workers for a four-month harvest. Its 12-month average is about 76, which would normally make it an ALE. Because the workforce exceeded 50 for only four months, and the extra employees were seasonal workers, the exception applies.

Seasonal worker vs. seasonal employee. These terms sound alike but serve different purposes. A seasonal worker, used for the ALE count, performs labor or services on a seasonal basis, such as retail workers hired for the holidays or farmworkers hired for harvest. A seasonal employee, used under the look-back measurement method, is hired into a position whose customary annual employment is six months or less. Once you're an ALE, temporary and seasonal employees come with their own tracking rules.

Who Doesn't Count Toward ALE Status?

Some workers and hours are left out of the calculation entirely:

• Independent contractors (1099 workers), since they aren't your employees. Classify workers carefully, because misclassification creates compliance risk of its own.
• Sole proprietors, partners in a partnership, and 2% S corporation shareholders.
• Employees with TRICARE or VA health coverage, for the months they have that coverage. This exclusion applies only to the ALE count.
• Hours of service performed outside the U.S. that generate foreign-source income.

How Do You Calculate ALE Status?

To calculate ALE status, use your workforce data from the prior calendar year and follow these steps:

1. Count your full-time employees for each month of the prior calendar year.
2. Calculate your FTEs for each month. Add the hours of service for all non-full-time employees (up to 120 per employee) and divide by 120. Keep any fractions for now.
3. Add each month's full-time employees and FTEs together, then add all 12 monthly totals.
4. Divide by 12. If the result isn't a whole number, round down.
5. Compare to 50. If the result is 50 or more, you're an ALE for the current calendar year. If it's 49 or less, you're not.

If your company is part of a group of related businesses, run the calculation across the entire group.

ALE Calculation Example

This example follows one the IRS uses. Company X had 40 full-time employees and 15 part-time employees in every month of the prior year. Each part-time employee worked 60 hours per month.

Company X averaged 47, so it's not an ALE. But it's close. If Company X had three more full-time employees each month, its average would reach 50 and it would be an ALE the following year. That's why growing employers should run the numbers well before year-end.

How Does ALE Status Work for New Employers?

A business that didn't exist on any business day of the prior calendar year can't look back at last year's numbers. Instead, it's an ALE for the current year if it reasonably expects to employ an average of at least 50 full-time employees (including FTEs) during the year and actually does, according to Treasury regulations.

What Are ALE Members and Aggregated ALE Groups?

The IRS doesn't look at each company in isolation. Related businesses are combined into a single employer when determining ALE status, even when they operate under separate names and EINs.

What Is an Aggregated ALE Group?

An aggregated ALE group is a group of related companies treated as a single employer for ALE purposes. Companies are aggregated when they're part of a controlled group, a group under common control, or an affiliated service group under Sections 414(b), (c), (m), and (o) of the Internal Revenue Code.

Common examples include a parent company and its subsidiaries, brother-sister companies with the same owners, and multiple LLCs owned by the same people. The ownership tests behind these groups get technical quickly, and the controlled group rules for multi-location businesses show how they apply in practice.

What Is an ALE Member?

An ALE member is each individual company within an aggregated ALE group. If the group as a whole meets the 50-employee threshold, every company in it is an ALE member, even one with only a handful of employees. Each ALE member:

• Files its own Form 1094-C and furnishes its own Forms 1095-C under its own EIN.
• Indicates on Form 1094-C that it's part of an aggregated ALE group and lists the group's other members.
• Is assessed separately for any employer mandate penalties.
  
  

Example: A Multi-Location Restaurant Group

Say two co-owners run five restaurants, each set up as its own LLC. Each location has about 12 full-time employees and enough part-time hours to add roughly four FTEs each month. On its own, each LLC averages about 16, far below 50. Combined, the group averages about 80. That makes the group an ALE, and all five LLCs are ALE members with their own reporting obligations.

For multi-entity businesses, the hardest part is often pulling hours from separate payroll systems into one count. ACA Reporter's payroll aggregation helps your team combine data across entities so you can see the group total in one place.

What Changes When You Become an ALE?

Once you're an ALE, two sets of obligations apply: the employer mandate and annual IRS reporting.

What Does the Employer Mandate Require?

The employer mandate requires ALEs to offer minimum essential coverage to at least 95% of full-time employees and their dependents. That coverage must also:

• Be affordable. For plan years beginning in 2027, coverage is affordable if the employee's required contribution for the lowest-cost, self-only option doesn't exceed 10.22% of household income, per Rev. Proc. 2025-25. Because employers rarely know household income, most use one of the IRS affordability safe harbors: W-2 wages, rate of pay, or the federal poverty line.
• Provide minimum value, meaning the plan pays for at least 60% of the total allowed cost of benefits.

The requirement is to offer coverage, not to enroll employees. Employees can decline, and a declined offer still counts toward the 95%.

What Are the Penalties for ALEs?

ALEs that don't meet the employer mandate may owe an employer shared responsibility payment. A penalty is triggered when at least one full-time employee buys Marketplace coverage and receives a premium tax credit. The 2027 amounts, per Rev. Proc. 2025-26, are:

The IRS assesses these penalties through Letter 226J, and the IRS employer shared responsibility Q&A explains how they're calculated. Under the Employer Reporting Improvement Act, employers now have 90 days to respond to a Letter 226J, and the IRS has six years to assess a penalty for a given year. Amounts adjust annually, and recent penalty increases show how quickly exposure can grow.

What If This Is Your First Year as an ALE?

A transition rule gives first-year ALEs some room in the first quarter. If you're an ALE for the first time, you generally won't owe employer mandate penalties for January through March for employees who weren't offered coverage in the prior year, as long as those employees are offered coverage by April 1.

Preparing takes time, so don't wait until ALE status is official. In the fall before your first ALE year, line up a health plan, choose how you'll determine full-time status (for example, the look-back measurement method), and set up hours tracking before January.

When Are ALE Reporting Deadlines?

ACA reporting happens early in the year after the tax year. For the 2026 tax year, ALEs must:

• Furnish Forms 1095-C to employees by March 2, 2027.
• File Forms 1094-C and 1095-C electronically with the IRS by March 31, 2027.

Late or incorrect filings carry their own penalties, separate from the employer mandate. Review the full list of IRS ACA reporting deadlines and penalties as you plan your filing calendar.

Do ALEs Have to File Electronically?

In most cases, yes. ALEs filing 10 or more information returns in aggregate, counting all return types such as W-2s and 1099s together, must file electronically through the IRS ACA Information Returns (AIR) system. This replaced the older 250-return threshold.

Can ALEs Furnish Forms 1095-C Only on Request?

Yes. Under the Paperwork Burden Reduction Act and IRS Notice 2025-15, ALEs can skip automatically sending Forms 1095-C if they post a clear, conspicuous notice on their website that employees can request a copy. To use this option:

• Post the notice by January 31 and keep it up through October 15.
• Include an email address, physical address, and telephone number for requests.
• Furnish any requested form by the later of March 2 or 30 days after the request.

This option applies to federal furnishing only. California, Massachusetts, New Jersey, Rhode Island, and the District of Columbia have their own individual mandates and state-level ACA reporting requirements.

Stay ahead of ALE tracking and reporting

Monitoring ALE status and preparing accurate 1094-C and 1095-C filings takes coordination across HR, payroll, and finance. ACA Reporter helps your team track employee status month to month, so you can spot threshold changes early and prepare filings with fewer surprises.
