For most HR teams, open enrollment still feels like a fall event. But the employers who come through it smoothly are the ones treating it as a mid-year project, not a fourth-quarter scramble.
That head start matters more in 2026 than in past years. Aon projects U.S. employer health care costs will rise 9.5% in 2026, pushing average costs past $17,000 per employee — the third consecutive year of near double-digit increases, driven by chronic condition prevalence, specialty drug spend, and rising GLP-1 utilization. Managing cost has become the #1 benefits priority for 62% of employers, up sharply from 38% just two years ago. At the same time, new IRS and ACA thresholds, updated HSA contribution limits, and evolving compliance requirements are all landing on HR's desk before the enrollment window even opens.
None of that is easy to absorb in a six-week fall sprint. Working through the details in Q2 or early Q3 gives your team room to make deliberate decisions instead of reactive ones.
We've put together a practical checklist to work through now:
Before renewal conversations start, review how each vendor performed this past year — claims turnaround, service issues, employee complaints, and cost trend relative to projections. Vendor optimization is now a top-three cost strategy for 37% of employers, whether that means renegotiating terms, consolidating point solutions, or replacing underperforming partners. Doing this in Q2 gives you leverage; doing it in October gives you none.
Pull participation and claims data from the last plan year and compare it to what you assumed at the last renewal. Aon's data shows that just 5% of health plan members drive 60% of medical and pharmacy spend, and more than half of high-cost claimants are predictable from existing data. That means the plan design decisions with the biggest cost impact are ones you can actually see coming, if you look early enough to act on them.
4. Rethink Your Communications Strategy and Start It Earlier
This is where the biggest employee-experience gaps show up. Research shows employees spend under an hour reviewing their benefit options, and 91% simply re-select the plan they had the year before. On the ACA exchanges, nearly 45% of 2025 enrollees were auto-enrolled without making an active choice at all. Passive decision-making isn't a communications failure alone, it's often a design failure, where reminders arrive too late and too generically to change behavior.
A multi-channel plan including email, text, portal messaging, and manager-level reminders, sequenced over weeks rather than days, consistently outperforms a single blast of open-enrollment emails. If you haven't mapped that sequence yet, mid-year is the time.
5. Evaluate Whether Employees Have Real Decision Support
Nearly half of employees report feeling unprepared going into open enrollment, and one in four say they feel only "a little" or "not at all" informed about their benefits. Static PDFs and FAQ pages don't close that gap. Interactive tools like cost comparisons, plan-selection calculators, and live decision support do. If your current setup relies mainly on documents and a shared inbox, this is the gap most worth closing before the season starts.
The employers who improve year over year treat enrollment as a loop, not a one-time event: analyzing who switched plans, whether projected savings materialized, and which messages actually drove action. Set this up as a standing step now, not an afterthought in December.
Every item above is manageable on its own. Coordinating all of them — vendor management, compliance, plan design, multi-channel communications, live decision support, and reporting across a single enrollment cycle is where most HR teams run out of bandwidth, especially with leaner budgets and leaner teams.
That coordination is exactly what YD 360° was built to handle. YouDecide's voluntary benefits outsourcing model combines voluntary benefits consulting, vendor and eligibility management, a single-slot payroll and eligibility platform, digital communications, and 24/7/365 live employee decision support into one managed solution, so your team isn't stitching together six vendors and three spreadsheets every fall.
