Years of reviewing employer benefit programs have taught me one hard truth: most compliance checklists catch the easy stuff while letting the real risks slide right through.
You know the drill. ERISA plan documents? Check. HIPAA privacy notices? Check. ACA reporting deadlines? Check. We tick those boxes and assume we're covered. But underneath, there's a whole layer of structural risk that rarely gets discussed at benefits committee meetings.
These five compliance blind spots trip up even the most well-intentioned HR teams. They are quiet liabilities that turn into major headaches when nobody is watching.
1. The Plan Document Trap
Most teams can confirm they have a Summary Plan Description. Fewer can confirm the plan document matches how the plan operates.
Plans frequently operate on one set of rules while the document describes another, and both courts and the DOL treat that gap seriously. If you have added a wellness reward, a preventive care incentive, or anything that ties health actions to financial accounts, the plan document needs to authorize it explicitly. Otherwise, participants can sue to recover benefits the document never authorized, and the DOL can impose penalties of $195 per day, up to $1,956 per request, for failing to produce plan documents it requests.
Update the plan document before launching a new benefit structure, not after. Every funding mechanism, every incentive, and every third-party arrangement needs to be spelled out in writing. The SPD summarizes the plan document, so updating one without the other recreates the same gap.
2. The Fiduciary Blind Spot in Automated Systems
Most plans have a claims appeals process. What they rarely document is who acts as fiduciary when the system makes a decision automatically.
When a benefits platform automatically approves preventive care, funds accounts, or triggers retirement contributions without human intervention, those actions function as claims decisions under ERISA. If nobody has documented who holds fiduciary responsibility for those decisions, the employer holds it by default.
Federal regulators have signaled attention to AI and automation in benefits administration, and ERISA's existing fiduciary duties already reach automated decisions. The fix is to write explicit fiduciary delegation language into every vendor service agreement so the employer isn't the default fiduciary for system-generated actions. Delegation shifts the decision-making role to the vendor, and the employer still selects and monitors that vendor.
3. The ACA Reporting-Funding Disconnect
Filing Forms 1094-C and 1095-C on time is the visible part. The less visible question is how every dollar flowing to employees affects your ACA numbers.
If your benefits system puts money into incentive accounts, wellness rewards, or health reimbursement arrangements, each dollar needs a classification. Is it compensation, a reimbursement, or a benefit? The answer drives your ACA reporting obligations and affordability calculations.
The IRS matches reporting against wage and benefit data, and a mismatch between your filings and your actual benefits structure draws a letter or an audit. Map every dollar flow against ACA, ERISA, and tax code requirements before you implement anything new.
4. The HIPAA Privacy Exception That Isn't
A Notice of Privacy Practices is standard. The harder question is whether your wellness program counts as part of the group health plan under HIPAA.
This distinction drives real obligations. When a system tracks preventive health actions and ties them to financial incentives, it's handling protected health information. Whether that system qualifies as a wellness program or falls under full group health plan HIPAA rules depends on how it is structured.
The HHS Office for Civil Rights has stayed busy on HIPAA enforcement, and programs that collect health data without proper safeguards draw scrutiny. Penalties can now reach $2,190,294 per identical provision per calendar year. Best practice is to have regulatory counsel make a formal determination about your program's classification, document it, and execute business associate agreements with every vendor that touches PHI.
5. The COBRA Continuation Nightmare
The 44-day notice deadline is well known. The part most teams leave unmapped is what participants are entitled to continue.
Consider an employer with a layered benefits program: a core plan, an incentive account, a pharmacy benefit, and retirement funding tied to health actions. When someone elects COBRA, what exactly are they getting? If your system funds accounts based on preventive behavior, does that funding continue during COBRA? If it doesn't, you may have a compliance problem.
Courts have been strict about requiring the same benefits during COBRA as during active employment. Health reimbursement arrangements and health FSAs carry their own continuation rules, so each account type needs a separate line in the COBRA analysis. Every benefit element must be mapped to continuation, and anything that can't be continued must be disclosed clearly upfront.
What This Means for Benefits Leaders
These five gaps share one cause: most compliance frameworks were built for a simpler era. Today's benefits systems cross multiple legal categories, use automation to make consequential decisions, and create complex financial flows between employers, employees, and vendors.
The approach that works is to map the entire system, every dollar flow, every data point, and every decision point, against every relevant regulatory framework, and keep that map current.
Before you sign off on any new benefits initiative, ask these questions:
- Plan Document Integration: Does this system require plan document updates, and who is responsible for that?
- Fiduciary Assignment: Who is the fiduciary for automated decisions, and is that documented in writing?
- ACA Mapping: How does every financial flow affect affordability calculations and reporting?
- HIPAA Classification: Is this system a wellness program or part of the group health plan? Have we documented that determination?
- COBRA Continuity: Can every benefit element be continued during COBRA? Is that communicated clearly to participants?
- Regulatory Counsel: Has this been reviewed by benefits regulatory counsel, not just benefits consultants?
- Documentation: Is there a written compliance framework that maps every dollar and data flow?
The Enforcement Numbers
These gaps are visible in enforcement results. The Labor Department's Employee Benefits Security Administration recovered more than $1.4 billion for plans, participants, and beneficiaries in fiscal year 2025, and more than half of that came from enforcement actions. The agency's year-end report names the themes behind these gaps: eliminating improper benefit plan provisions and improving fiduciary governance. Document mismatches and unassigned fiduciary responsibility are the kinds of failures those recoveries target.
Final Thought
The benefits systems that survive regulatory scrutiny and avoid these hidden liabilities treat compliance as a design principle rather than a checklist. What matters is whether a system was built to stay compliant as regulations evolve and audits arrive.
The best systems solve compliance problems first, then layer the benefits value on top. WellthCare™ is exactly that kind of system: built compliance-first, with every dollar flow and decision mapped to ERISA, HIPAA, and ACA frameworks and supported by formal legal opinions.
