The threshold is fifty, it is measured on last year’s payroll, and nothing warns you when you cross it. A practice that added two associates and a few medical assistants in 2025, or a contractor who leaned on part-time labor all summer, can become an Applicable Large Employer without ever having the conversation. The first notice is often Letter 226-J, proposing a six-figure penalty for a plan year that closed eighteen months ago.
The mandate is not new. But three things make 2026 the year to check where you stand: the penalties jumped, the affordability percentage moved to its most employer-friendly level in years, and two 2024 laws rewrote the enforcement rules.
How You Become an Applicable Large Employer Without Noticing
ALE status looks backward. If you averaged 50 or more full-time employees, including equivalents, across the prior calendar year, the mandate applies now: your 2026 obligations were set by your 2025 headcount. Two definitions do most of the damage:
- Full-time employee: anyone averaging 30 hours per week, or 130 hours per month. Not 40. Thirty.
- Full-time equivalent: add the monthly hours of everyone who is not full-time, cap each person at 120 hours, divide by 120.
Counting to Fifty: A Practice That Did Not Think It Qualified
- 32 employees at 130+ hours per month: 32 full-time employees.
- 24 part-timers averaging 95 hours per month: 2,280 hours ÷ 120 = 19 full-time equivalents.
- Monthly total: 51 — an ALE, despite offering coverage to only 32 people.
Two rules catch people. Businesses under common ownership are aggregated, so three clinics and a management company owned by the same physicians count as one employer. And workers you treat as contractors count if they are legally employees, which makes worker classification an ACA issue too. The one narrow escape hatch: exceeding 50 for no more than 120 days, solely because of seasonal workers.
The Two Penalties, and Why the First One Is the Dangerous One
The 2026 amounts, indexed annually, rose sharply.
| Penalty | What Triggers It | 2026 Amount | How It Is Measured |
|---|---|---|---|
| Section 4980H(a) | No offer of minimum essential coverage to at least 95% of full-time employees and dependents, and one gets a premium tax credit | $3,340/year ($278.33/month) | Every full-time employee, minus 30 |
| Section 4980H(b) | Coverage offered, but unaffordable or below minimum value | $5,010/year ($417.50/month) | Only employees who actually receive a credit; capped at the (a) amount |
The larger per-employee number is the less dangerous one. An employer with 60 full-time employees making no qualifying offer, with one employee claiming a subsidy, faces (60 − 30) × $3,340 = $100,200. The same employer offering coverage one employee finds unaffordable owes $5,010.
The (a) penalty does not scale with how many employees went to the exchange. One subsidized employee triggers a bill computed on your entire full-time workforce — and it is not tax deductible.
The 9.96 Percent Affordability Test
For plan years beginning in 2026, an employee’s required contribution for the lowest-cost self-only option meeting minimum value cannot exceed 9.96 percent of household income. Since no employer knows household income, the regulations offer three safe harbors.
The Three Safe Harbors
- Form W-2: capped at 9.96% of Box 1 wages from your company. Box 1 drops when an employee defers into a 401(k) — a quiet way to fail a test you thought you passed.
- Rate of pay: 9.96% of hourly rate × 130. Predictable and the most common choice.
- Federal poverty line: capped at $129.90 per month for 2026 calendar-year plans. The priciest option, and an automatic pass on audit.
Affordability is only half the test: the plan must also deliver minimum value, covering at least 60 percent of allowed costs. Employers using an individual coverage HRA run the same math against the reimbursement amount.
Two Laws That Quietly Changed the Enforcement Math
The Employer Reporting Improvement Act and the Paperwork Burden Reduction Act made three changes that matter more than their names suggest.
- 90 days to respond to Letter 226-J, up from 30. The old window often closed before the letter found the right desk.
- A six-year statute of limitations on these assessments, running from the Form 1095-C due date or the filing date if later. The IRS had previously argued no limitations period applied at all. Bounded is better, but a 2026 filing stays open into 2033.
- Forms 1095-C on request only, provided you post a clear, conspicuous, accessible notice telling employees how to ask. Requested forms go out within 30 days or by January 31, whichever is later.
The furnishing relief is not filing relief: Forms 1094-C and 1095-C still go to the IRS on schedule, and e-filing is mandatory at ten or more returns.
If Letter 226-J Lands on Your Desk
- Calendar the response date the day it arrives. Ninety days is generous only if the clock starts on time.
- Work the employee list first. The attached table names each employee who received a credit, month by month. Terminated staff, part-timers coded as full-time, and employees in a waiting period turn up constantly.
- Rebuild the offer record: enrollment files, waivers, plan documents, contribution rates by month.
- Fix the codes. Most assessments trace to lines 14 and 16 of Form 1095-C, where a clerical error reads as a failure to offer coverage.
- Respond in writing with the disagreement form and a corrected employee schedule. Silence turns the proposal into a demand for payment.
Most 226-J assessments are data problems, not coverage problems: the employer offered good insurance and reported it badly. That is fixable only with records that reconcile, which is why we run these responses out of our payroll and financial reporting teams jointly.
What to Do Before Your Next Hire
The mandate is one of the few compliance costs you can see coming.
- Count full-time equivalents monthly, not once at year end. One busy quarter can carry you over.
- Model the true cost of the 50th hire: not one salary, but coverage for everyone, plus reporting and penalty exposure.
- Audit last year’s 1095-C codes while the people who made those offers still work for you, and set a look-back measurement period for variable-hour staff.
For growing practices this belongs in the same conversation as provider compensation and staffing ratios, which is how our medical practice finance and CFO advisory teams handle it — and the math only works if the hours data is clean, which starts with bookkeeping that matches payroll.
The Bottom Line
Fifty full-time equivalents is a bright line with a long echo: your 2025 payroll set your 2026 duties, and your 2026 filings stay open into 2033. The math rewards attention — $3,340 per employee across your whole workforce for getting the offer wrong, against $129.90 a month for a contribution affordable by definition. The employers who get hurt are rarely the ones who decided against offering coverage. They are the ones who never counted.
