A planning estimate, not legal advice. The test uses all 12 months of the prior calendar year and counts related companies together. Confirm with your tax advisor.
How does the ACA count employees?
An employer is an applicable large employer when its average for the prior calendar year is at least 50 full-time employees, counting full-time equivalents. A full-time employee averages at least 30 hours a week, or 130 hours in a month. Everyone else is converted to a full-time equivalent by adding their monthly hours, up to 120 per person, and dividing by 120. You add the full-time count and the equivalents for each month, average the 12 months, and round the average down.
What changes the count?
Related companies under common control are counted as one employer, so a second entity can push a small business over the line. Seasonal workers can be excluded when the average passes 50 for 120 days or fewer, which is four calendar months, in the year. Staff of a franchisee are counted by that franchisee, not the franchisor, unless the two are related.
Common questions
What are 130 hours in a month based on?
It is the monthly equivalent of 30 hours a week. An employee who works 130 hours in a calendar month counts as full-time for that month, even if no single week reaches 30 hours.
Do owners and family members count?
Sole proprietors, partners in a partnership and two-percent S corporation shareholders are not employees for this count. Other owners who work for pay are generally counted. Ask your tax advisor about a family-owned company. See the tax treatment for sole proprietors, partners and S corporation owners.
Do we count staff who decline coverage?
Yes. The count is about hours worked, not enrollment. Employees who waive coverage still count toward the 50.
What happens once we reach 50?
You owe the 1094-C and 1095-C filings and face the employer shared responsibility rules, which means offering affordable minimum-value coverage to full-time employees or paying a penalty. Our penalty calculator shows the exposure.
