ICHRA solves real problems, but it isn't free of trade-offs. Here's a straight comparison — including the parts that don't make it into most sales pitches.
Your workforce is seasonal, hourly, remote, or multi-location; your group renewal keeps climbing; you can't hit group participation minimums; or you don't currently offer any benefit and want a budgetable way to start.
You have a large, stable, mostly full-time workforce concentrated in one area; your team strongly values a single chosen network and plan design; or you have HR resources dedicated to managing group plan administration well.
Neither is universally better — it depends on your workforce and priorities. ICHRA tends to win on cost predictability, flexibility, and accessibility for smaller or variable workforces; group plans tend to win on simplicity for the employee and consistency of network access.
Underestimating the administrative setup work — plan documents, class design, and affordability calculations — and underestimating how much employee education is needed the first year, since many employees have never shopped for their own individual plan before.
Yes, employers can move back to a group plan in a future plan year — though it's worth treating that as a real possibility to plan for, not just a theoretical escape hatch, since re-underwriting a group plan after time away isn't always fast or cheap.
