Picture the whiteboard in your office right now. It might show revenue targets for next year. Maybe you’re scoping out a hiring plan by quarter. Maybe there’s a key launch date, circled in red. In the course of accomplishing those goals, there’s a headcount number you’re building toward. What you might not see is the line where that number quietly changes what employment law requires of you as a business. We previously covered the first of these milestones in Growing Past 15: the point where laws like Title VII, the ADA, and the Pregnant Workers Fairness Act all start applying to your business. If you’ve crossed that line already, you know the feeling of added administration and activity that HR has to pick up. More thresholds await growing businesses between 15 and 100 employees. Each one brings new requirements, new benefits considerations, and a different answer to the question of how much HR support you need. Why Headcount Belongs on Your Growth Roadmap Most growth planning happens in one direction: you forecast revenue, then you work backward to the resources—including headcount—required to meet that goal. Compliance rarely gets the same treatment, even though it’s just as predictable. You know your business better than any regulator does, and you can usually see a milestone like 50 employees coming a year out. The businesses that get caught off guard are the ones growing without a map. The requirements below are fixed, published, and knowable well in advance. The only variable is whether you’re looking at them before or after you need them. What Changes at Each Threshold At 20 Employees Federal COBRA becomes mandatory. If you sponsor a group health plan, departing employees and their dependents gain the right to continue that coverage, at their own cost, after a qualifying event like termination or a reduction in hours. The Age Discrimination in Employment Act also applies at this threshold, extending protections to employees and applicants 40 and older. At 50 Employees The Family and Medical Leave Act (FMLA) applies once you have 50 or more employees within a 75-mile radius, giving eligible employees up to 12 weeks of unpaid, job-protected leave for qualifying medical and family reasons. At the same threshold, the Affordable Care Act‘s employer mandate applies. Once you average 50 full-time equivalent employees over the prior year, you’re an Applicable Large Employer, required to offer affordable, minimum-value coverage to at least 95% of your full-time workforce or face penalties tied to your full-time headcount. For a deeper look at what “affordable” and “minimum value” mean in practice, our guide to required and supplemental benefits is a good next stop. At 100 Employees Federal EEO-1 reporting becomes required, meaning you’ll submit annual workforce demographic data to the Equal Employment Opportunity Commission (EEOC). In New York specifically, paid sick leave entitlement steps up from 40 to 56 hours per year. Three thresholds, three different categories of risk: benefits obligations, leave obligations, and reporting obligations. If your growth goal for the year ahead takes you across one of those hiring milestones, now is the time to prepare for what else might change alongside that growth. When to Add Additional Support for HR The work of HR remains the same across all these milestones. As you grow, running your business gets more complex, and that requires more administrative work on the HR side. It requires building new processes and systems, which might mean more HR staff or different HR technology and tools. The goal here is to predict and anticipate what you can on this journey of growth. It’s better to think about what changes in your business at the 50-employee threshold when your headcount is 30 or 40 than when it’s at 49. This isn’t just a compliance discussion. It comes back to how you allot your time as leaders of a business. Every hour spent figuring out what FMLA eligibility tracking requires or piecing together ACA reporting for the first time is an hour not spent on the next hire, the next deal, or the next decision that actually grows the business. Having the right HR processes and support in place is how you get that time back. Here are some questions that might be helpful to ask of yourself and your team if you’re planning for future growth and wondering what that means for HR: Do you know who owns compliance tracking for your business, and do you know what changes are ahead at your next threshold? How many hours did your owner (and/or other key leaders) spend working on HR activities and administration last quarter? Is there one person holding all the knowledge about how HR works in your business, and what happens if that person is out of office? What happens if they leave the business? Are you still using the same HR systems and processes today that were used when you had half your current headcount? Do you need to make updates anywhere? Put Headcount on the Map Those plans you’ve been making for 2027 and beyond? The strategy’s not complete until you know how you plan to hire the people who will make those goals possible. Growing your HR approach is a core part of growing your business. Partnering with a Professional Employer Organization (PEO) like Employer Services Corporation is one way you can manage the complexity of HR and cut down on administrative time spent by your senior leaders, so they can focus on the most impactful work they can do. If you’re approaching a major hiring milestone in the next year, let’s build that roadmap together before you cross it. Talk to our team this week about what’s ahead.
