Health insurance — the fifty that is not fifty people, and the season that can exempt you

Health insurance is the one obligation on this site that arrives by arithmetic rather than by decision. Nothing happens when you hire your fiftieth person. Something happens when a formula, applied to last year’s hours, returns fifty — and those are different events, often a year apart.

Unlike almost everything else here, this is federal rather than Ohio law. Ohio adds no employer mandate of its own on top of it.

Fifty is not fifty people

An applicable large employer is one that employed an average of at least fifty full-time employees on business days during the preceding calendar year.¹

Two words in that sentence do most of the damage.

“Full-time” means an average of at least thirty hours of service per week.¹ Not forty. Thirty is squarely inside the range a restaurant schedules people at without thinking of them as full-time staff.

“Preceding” means the determination looks backward. You are an applicable large employer this year because of what happened last year, which means the moment to model this is a year before you expect to care about it.

And then the part that makes it a formula:

a number of full-time employees determined by dividing the aggregate number of hours of service of employees who are not full-time employees for the month by 120¹

Every part-time hour counts. Add up all hours worked in a month by everyone who is not full-time, divide by 120, and add the result to your full-time head count. A hundred and twenty hours is one equivalent — roughly two people at fifteen hours a week.

This is why the threshold arrives before it feels like it should. Work an example. Say you have thirty-five full-time staff and twenty-five part-timers averaging sixteen hours a week. Sixteen hours a week is about sixty-nine hours a month, so the part-timers contribute roughly 25 × 69 = 1,725 hours, and 1,725 ÷ 120 is about fourteen equivalents. Thirty-five plus fourteen is forty-nine.

Sixty people on the schedule, and you are one part-timer’s extra shifts from being an applicable large employer — with nobody in the building describing the place as employing fifty.

Do the calculation. Do not estimate it from the size of the roster, and do not estimate it from how the business feels.

The scheduling move that does not work

The common response is to hold people under thirty hours. That does change something: it changes who you must offer coverage to, because the offer obligation runs to full-time employees.

It does not keep you under fifty. Hours worked by people who are not full-time are exactly what the 120-hour divisor converts.¹ Capping hours moves those hours from the first term of the sum into the second. It does not remove them.

Worth being clear about, because “keep everyone at twenty-nine” is advice that circulates in this industry as though it solved the threshold question. It solves a different question.

The seasonal exemption, which is real and narrow

This is the provision most relevant to a market with a genuine patio season, and it is worth reading precisely.

You are not treated as exceeding fifty if:

(I) [the excess existed] for 120 days or fewer during the calendar year, and (II) the employees in excess of 50 employed during such 120-day period were seasonal workers¹

Both conditions. The overage has to be short — 120 days is about four months — and the people making up the excess have to be seasonal workers. A seasonal worker is one performing labor or services on a seasonal basis as defined by the Secretary of Labor, including workers covered by 29 C.F.R. 500.20(s)(1) and retail workers employed exclusively during holiday seasons.¹

So a restaurant that staffs up in May and back down in September, where the extra bodies are the seasonal ones, has a real argument. A restaurant that grew in April and stayed grown does not, regardless of how seasonal the revenue felt.

If you are near the line and seasonal, this is worth documenting as it happens — who was hired, for what period, on what basis — rather than reconstructing it from memory a year later when the determination is being made.

Separate entities do not help

All persons treated as a single employer under the controlled group rules of section 414 are treated as one employer.¹ Four restaurants of fifteen staff each, in four LLCs you own, are one employer of sixty.³

When a second location changes the rules covers this alongside the other thresholds that add up, and it is the guide to read if you are growing rather than opening.

The asymmetry worth understanding

If you cross the threshold, there are two different exposures, and they are not the same size.

Offering nothing. If you fail to offer minimum essential coverage to full-time employees and at least one of them receives a premium tax credit on the exchange, the monthly assessment is one twelfth of a base $2,000 figure applied across your full-time workforce rather than only to the person who got the credit.¹

With one significant reduction. The number of full-time employees is reduced by thirty solely for calculating the subsection (a) payment and the overall cap on the subsection (b) payment.¹ That matters a great deal at the bottom of the range: an employer with fifty full-time employees is assessed on twenty, not fifty. The first thirty are, in effect, free — which is why the exposure ramps rather than switching on at full force the moment you cross the line.

Offering something that falls short. If you do offer coverage but an employee still qualifies for a credit, the monthly assessment is one twelfth of a base $3,000 figure, but only for each employee who actually received the credit — and the total is capped at what the first calculation would have produced.¹

The per-employee figure is higher in the second case and the population it applies to is far smaller. Offering imperfect coverage is materially cheaper than offering none, and it is capped at the cost of offering none. That is the practical shape of the decision, and it is the opposite of the intuition that partial compliance is the worst of both worlds.

Both dollar figures are base amounts. The statute adjusts them by the premium adjustment percentage for the calendar year,¹ so the operative numbers are meaningfully higher than $2,000 and $3,000 and change annually. We are not printing a current figure here, because a number you plan around needs to come from the IRS for the year in question rather than from a page that was accurate once.³

If you are under fifty and want to offer it anyway

There is no mandate below the threshold. There is a credit.

An employer with no more than twenty-five full-time-equivalent employees, whose average annual wages fall below a limit set at twice an indexed dollar amount, may claim a credit — provided the employer makes a uniform nonelective contribution of at least fifty percent of the premium cost, and buys the coverage through an Exchange. For years beginning after 2013 the credit is fifty percent of employer contributions, or thirty-five percent for a tax-exempt employer, and it runs for a two-consecutive-year credit period.²

Three things about that in practice. The wage limit is indexed, so check the current figure rather than a number from an article. The fifty percent contribution is a floor, not a target. And the two-year window means the credit is a bridge rather than an ongoing subsidy — useful, but not something to build a permanent budget on.

For a small kitchen, the credit plus the retention argument is usually the whole case. This industry’s turnover is expensive in ways that do not appear on the insurance line.

The short version

• Fifty full-time employees including equivalents, averaged over the preceding calendar year.¹
• Full-time is thirty hours, and non-full-time hours convert at ÷ 120 per month.¹
• Capping hours at twenty-nine does not keep you under fifty — those hours still convert.¹
• Seasonal exemption: overage of 120 days or fewer and the excess were seasonal workers. Both.¹
• Common ownership aggregates under section 414.¹
• Offering nothing is assessed across your full-time workforce, less thirty; offering something short is assessed only on those who got a credit, and capped. Do not treat partial compliance as pointless.¹
• Under twenty-five equivalents with low average wages, there is a two-year credit at fifty percent.²

This is federal tax law, the dollar figures are indexed annually, and the determination depends on your actual hours and ownership structure. Everything above was read from the cited sources on the date at the top of this page. Model your own numbers with a benefits adviser or accountant before you rely on which side of the line you are on — this is the one threshold on this site where being wrong is measured per employee per month.
