ACA Employer Mandate: ALE Status, Affordability and Penalties

The ACA employer mandate generally applies to employers averaging at least 50 full-time employees, including full-time equivalents, in the prior calendar year. Applicable large employers must evaluate coverage offers, minimum value and affordability to avoid potential penalties. For 2026 and 2027 planning, use the indexed figures for the correct year, not the original PPACA amounts.

Determine applicable large employer status first

An applicable large employer (ALE) can be a single company or a group of related employers. Add each month’s full-time employees and full-time equivalents for the previous calendar year, then divide the annual total by 12. Common-ownership aggregation can bring a smaller entity into an ALE group even when its own payroll is below the threshold. Each ALE member’s liability is generally determined separately.

A full-time employee generally averages at least 30 hours of service weekly or 130 hours monthly. For the ALE size test, combine non-full-time hours, capped at 120 hours per employee per month, and divide by 120. Those equivalents establish employer size; they are not extra individual employees to whom an offer must be made. The IRS employer shared responsibility questions and answers explain counting, controlled groups and exceptions.

Hypothetical example: a business has 40 full-time employees and 20 part-time employees working 60 hours monthly throughout the prior year. The part-time hours produce 10 equivalents, making the average 50 for the ALE test. A seasonal-worker exception has specific conditions; simply labeling a worker seasonal or hiring for fewer than six months does not automatically exempt the company.

Offer coverage to the right employees and dependents

The Section 4980H(a) offer test generally requires minimum essential coverage offered to at least 95% of full-time employees and their dependents, subject to the regulation’s limited allowance for all but five employees if greater. Dependents generally include children until age 26, not spouses. Offering coverage is different from requiring employees to enroll: document the offer and any waiver.

Minimum essential coverage and minimum value are different tests. A plan generally provides minimum value if it covers at least 60% of expected allowed benefit costs and substantially covers inpatient hospital and physician services. Merely passing the broad offer test does not eliminate employee-specific risk when coverage is unaffordable, lacks minimum value, or a full-time employee was among those not offered coverage.

Use year-specific affordability and penalty figures

Affordability percentages come from Revenue Procedure 2025-25 and Revenue Procedure 2026-26. Penalty amounts come from Revenue Procedure 2025-26 and Revenue Procedure 2026-22. The table shows annualized amounts, not automatic invoices. Penalties are determined monthly, and the affordability percentage follows the plan year while the penalty amount follows the calendar year.

Section 4980H(a) can apply when the broad offer test fails and at least one full-time employee receives a Marketplace premium tax credit. Its calculation generally counts all full-time employees, not equivalents, minus 30, with the reduction allocated among related ALE members. Section 4980H(b) generally concerns each full-time employee receiving a credit when no qualifying affordable, minimum-value offer protects the employer; its total is capped at the hypothetical Section 4980H(a) amount.

Choose and document an affordability safe harbor

Employer-mandate affordability generally tests the employee’s required contribution for the lowest-cost self-only coverage providing minimum value. Because employers rarely know household income, the IRS permits Form W-2 wages, rate-of-pay and federal-poverty-line safe harbors. These protect the employer under Section 4980H when properly applied; they do not decide an employee’s actual premium tax credit eligibility.

The W-2 method uses Box 1 wages and requires attention to annual compensation and adjustments. The hourly rate-of-pay method generally uses 130 hours multiplied by the applicable hourly rate, subject to the rules for rate changes; salaried employees have separate conditions. The federal-poverty-line method uses the applicable single-person poverty guideline. Apply a chosen method consistently to reasonable employee categories and keep the calculation, contribution schedule and effective dates.

Build the compliance review into renewal

1. Confirm prior-year employee counts and related-company ownership before selecting the ALE reporting approach.
2. Identify full-time employees using the permitted monthly or look-back measurement method and document eligibility dates.
3. Check the lowest-cost minimum-value option and employee contributions against the correct plan-year affordability threshold.
4. Record offers, dependent eligibility, waivers, monthly enrollment and any reporting corrections.

Use the ACA Forms 1094 and 1095 reporting guide for the separate filing obligation. If the IRS has already proposed an assessment, follow the Letter 226-J response checklist rather than using current-year numbers for a historical dispute. The federal individual shared responsibility payment has been zero since tax year 2019, according to IRS individual and family guidance; that does not repeal the employer mandate.

Primary Care Insurance Solutions (PCI Solutions) can help organize plan offers and contribution records through HR compliance and benefits administration support. Tax and benefits counsel should resolve controlled-group, assessment and legal interpretations. A coverage purchase alone does not establish compliance without accurate employee data and a defensible administrative process.
