If you work in benefits, you've probably noticed something this year. It's not one dramatic new rule that's changing how brokers and HR teams operate — it's a shift in what regulators expect employers to be able to show.
DOL audits are up. IRS affordability thresholds have moved again. And quiet mismatches between payroll, HRIS, and carrier systems are already showing up as penalty notices and 1095-C corrections. None of this usually starts with an employer trying to cut corners. It starts with a data gap nobody caught in time.
This piece breaks down what's actually driving compliance risk heading into open enrollment 2026, the areas getting the most regulatory attention, and a practical checklist to work through before OE volume takes over your calendar. At the end, we'll also point you to a free 30-minute briefing that walks through all of it live.
The shift from "more rules" to "more accountability"
It's tempting to treat every compliance update as a new hoop to jump through. But the more useful way to think about 2026 is this: federal agencies aren't just writing new requirements — they're checking whether employers can demonstrate that existing ones are being followed.
That means reliable internal processes, accurate data, documented vendor oversight, and a paper trail showing how decisions got made. "Our carrier handles that" or "our TPA files that for us" isn't the shield it used to be. A vendor can perform the work, but the employer or plan fiduciary usually still owns the responsibility for making sure the work is correct.
The scale here matters too. The Department of Labor's Employee Benefits Security Administration (EBSA) oversees benefits coverage for more than 156 million workers, retirees, and family members across roughly 2.6 million health plans. That's the backdrop for why plan administration, fiduciary oversight, and participant access have stayed squarely in enforcement crosshairs.
Four areas where compliance risk is concentrated right now
1. Plan affordability. The ACA affordability safe harbor percentage changes almost every year, and applying last year's number to this year's contributions is one of the most common — and most avoidable — errors employers make. Getting this wrong doesn't just create a compliance gap; it flows directly into 1095-C corrections and potential IRS penalty assessments down the line.
2. Participant access. Especially for mental health and substance use disorder benefits, the question has shifted from "is it in the plan document" to "can someone actually use it." More on this below.
3. Data and documentation. This is the one that quietly connects to almost every other issue on this list. Incorrect eligibility data, payroll and HRIS mismatches, and missing documentation don't usually cause a problem on their own — they cause a problem when they collide with an audit, a claim, or a filing deadline.
4. Vendor and fiduciary oversight. Outsourcing a function (COBRA administration, ACA reporting, claims processing) doesn't outsource accountability for it. Employers are increasingly expected to know what their vendors are doing, how well they're doing it, and what happens when something goes wrong.
Where compliance problems actually begin
Most compliance failures don't start with bad intentions — they start with an operational gap that nobody flagged in time. In practice, that usually looks like:
- Incorrect eligibility data (a status change that updates in one system but not another)
- Payroll and HRIS records that quietly drift out of sync
- Outdated plan assumptions carried over from a prior year
- Unclear ownership of vendor responsibilities — the vendor assumes the employer filed it, the employer assumes the vendor did
- Missing documentation showing how a decision, correction, or review was made
Here's the part that matters most: incorrect data or an outdated percentage can usually be identified and fixed. But if an employer can't explain how a decision was made, who reviewed it, or whether a vendor was being monitored, it becomes much harder to demonstrate a prudent process — which is often the actual standard regulators are evaluating against.
Mental health parity: coverage on paper isn't access in practice
Mental health parity is one of the more technical compliance areas, but the underlying question is simple: can someone actually get care, not just find the benefit listed in a plan document.
Plans generally can't apply more restrictive financial requirements, treatment limits, prior authorization rules, or medical-necessity standards to mental health and substance use benefits than they apply to comparable medical and surgical benefits. Requirements taking effect with 2026 plan years go further, adding expectations around meaningful benefits, non-discriminatory design factors, supporting outcomes data, and comparative analyses.
In practice, that means "we cover behavioral health" isn't a complete answer anymore. The better question is whether participants can find an in-network provider, get authorization on comparable timelines, and access treatment without unreasonable limitations — and whether the plan has the data and analysis to back that up if asked.
Cybersecurity is now a benefits compliance issue, not just an IT one
Benefit plans hold some of the most sensitive data an employee has: Social Security numbers, banking details, health information, dependent records, and account balances. That's exactly why EBSA named cybersecurity a national enforcement priority.
HR and benefits teams don't need to become security engineers, but they do need to know whether their vendors have real safeguards in place: incident-response procedures, access controls, data-retention practices, and clear contractual responsibility for what happens if something goes wrong. "The vendor is secure" isn't a complete answer either — the follow-up question is what happens, and who's notified, if that ever stops being true.
A checklist to work through before open enrollment
- Recalculate affordability using the current year's threshold and your organization's selected safe harbor method — don't assume payroll systems updated the percentage automatically.
- Audit eligibility — full-time status, waiting periods, dependent eligibility, leave situations, and any changes from recent hiring, acquisitions, or system migrations.
- Reconcile your systems — payroll, HRIS, carrier, and TPA records should tell the same story. They rarely do on the first pass, which is exactly why this step matters.
- Confirm vendor responsibilities — document who files, who furnishes notices, who retains records, and who owns each deadline. A simple responsibility matrix prevents months of confusion later.
- Update the compliance calendar — Form 5500, ACA reporting, COBRA and required notices, RxDC reporting, gag clause attestations, and any state-specific obligations, each with a named owner. A deadline with no owner is really just a suggestion.
Why now, not November
Compliance work has a rhythm. Mid-year is when there's still time to catch inconsistencies, clarify who owns what, and fix small issues while they're still small. Once open enrollment begins, that bandwidth disappears — and by year-end, most teams are focused entirely on producing forms and hitting deadlines, which is the worst possible moment to discover that payroll and carrier records have disagreed since spring.
The best filing season is usually an uneventful one, and uneventful gets earned months in advance.
