For years, the conversation around health savings accounts has followed a familiar rhythm: contribution limits adjust slightly, maybe a new eligible expense gets added, and HR teams update their communications accordingly. Manageable. Predictable. Routine.
The One Big Beautiful Bill (OBBB) changes that rhythm entirely.
The changes under this bill legislative changes under this bill represent one of the most significant expansions of HSA and FSA rules in recent memory, and for employers, benefits brokers, and HR leaders, the implications are substantial. More flexibility for employees. More complexity to administer. And a real opportunity to build smarter, more valuable benefits programs for the people who depend on them.
Here's what you need to know, and what you should be doing about it right now.
What is the OBBB, and why does it matter for benefits?
OBBB is sweeping legislation that touches many corners of tax and economic policy, but its impact on employer-sponsored health benefits is where HR teams need to focus their attention. Among its most consequential provisions are meaningful expansions to the rules governing health savings accounts (HSAs) and flexible spending accounts (FSAs), giving both employers and employees more room to save, spend, and plan.
If you want the full legislative picture, our detailed breakdown of the OBBB's impact on employee benefits is a good place to start. But here, we're focused on what the HSA and FSA changes mean in practice, for your plan design, your employees, and your compliance obligations.
The key HSA and FSA changes you need to understand
Higher contribution limits and broader eligibility
One of the most employee-friendly changes in the bill is the expansion of HSA contribution limits. For employees who have historically felt constrained by annual caps, this opens real room to build meaningful health savings, particularly for those using their HSA as a long-term tax-advantaged investment vehicle rather than just a spending account.
Eligibility rules are also being relaxed in important ways. More employees will qualify to contribute to an HSA, including in situations that previously disqualified them, such as certain Medicare enrollment scenarios and coverage combinations. This is a significant shift. Organizations that previously couldn't offer meaningful HSA benefits to portions of their workforce may now be able to close that gap.
Expanded definition of eligible expenses
The bill broadens what can be paid for with HSA and FSA funds, including certain over-the-counter items, wellness-related expenses, and, in some cases, telehealth and alternative care services. For employees, this means more purchasing power from the dollars they've already set aside. For employers, it means an opportunity to communicate new value from benefits that are already in place.
This is exactly the kind of change that gets lost in implementation if it isn't communicated proactively. Employees who don't know what they can now spend their FSA dollars on will leave that value on the table and blame their benefits program for being confusing.
FSA rollover and grace period improvements
FSA rules have long been a source of frustration; the use-it-or-lose-it structure discourages employees from contributing as aggressively as they otherwise might. The bill introduces improvements to rollover allowances and grace period provisions that meaningfully reduce that risk. For HR teams, this removes one of the most common objections employees raise during open enrollment. For employees, it makes the FSA a far more attractive savings vehicle than it has historically been.
HSA and direct primary care, a growing combination
The bill also clarifies and, in some areas, expands the compatibility between HSAs and direct primary care (DPC) arrangements. This is a space worth watching closely. As more employers explore DPC as a way to give employees better access to primary care without driving up costs, understanding how it interacts with HSA eligibility becomes essential. Getting it wrong has compliance consequences. Getting it right creates a genuinely differentiated benefits offering.
What this means for your benefits strategy
These changes don't just affect account mechanics. They affect how you should be thinking about your entire benefits architecture.
Open enrollment just became more complex and more important.
Expanded contribution limits and eligibility rules mean employees will have more decisions to make and more to understand. The employers who invest in clear, accessible communication this enrollment season will see higher participation rates and more satisfied employees. Maximizing HSA and FSA participation starts long before the enrollment window opens, and 2026 is the year to get that strategy right.
Plan design needs a fresh look.
If your current benefits structure was built around the old rules, it may no longer be optimized for your workforce. Higher contribution limits are only valuable if employees understand them and feel confident using them. Broader eligibility only matters if your plan is set up to capture it. This is a good moment to audit what you have and ask whether it still fits.
Consumer spending behavior is shifting, too.
Employees are becoming more sophisticated about how they use their HSA and FSA dollars, and the latest trends in HSA and FSA consumer spending reflect a workforce that is increasingly treating these accounts as strategic financial tools, not just reimbursement mechanisms. Your benefits communications and plan design should reflect that evolution.
Compliance can't be an afterthought.
Every expansion in HSA and FSA rules comes with a corresponding expansion in what can go wrong from a compliance standpoint. Eligibility determinations, contribution limits, eligible expense definitions, and non-discrimination testing all of these need to reflect the updated rules, not last year's. Organizations that treat compliance as a year-end exercise rather than a year-round discipline are the ones that end up with corrections, penalties, and unhappy employees.
Where Clarity comes in
At Clarity Benefit Solutions, HSA administration isn't a side offering; it's core to what we do. We've built our platform and our team around the belief that account-based health benefits should be easy to administer, easy to use, and easy to understand.
With changes of this magnitude coming through the One Big Beautiful Bill, that expertise matters more than ever. We're helping employers across the country understand what the new rules mean for their specific plans, update their compliance posture accordingly, and communicate the changes to employees in ways that drive real engagement, not confusion.
Whether you're starting from scratch with an HSA program, looking to optimize an existing one, or trying to figure out how the new rules apply to your particular workforce and plan structure, our team is here to help you navigate it with confidence.
Because the best HSA benefits solution isn't just the one with the most features. It's the one that works for your people, stays compliant with the rules, and gets better every year.
Wrapping up
All of this equates to a genuine opportunity for employers who are paying attention. More contribution room. Broader eligibility. Better FSA flexibility. A stronger case for HSAs as long-term financial tools. All of it points in the same direction, toward a benefits program that delivers more value to employees and more return on investment for employers.
But opportunity and outcome are not the same thing. The employers who capture this moment are the ones who act, who audit their plans, update their communications, partner with the right administrators, and treat these changes as a strategic lever rather than a compliance item to check off.
If you're ready to make the most of what's coming, we're ready to help.
