The HSA custodian a carrier bundles in is convenient for the carrier. Employees live with its fees for years.
An HSA belongs to the employee and stays with them long after they leave, so fees and investment options compound over decades, not plan years. We evaluate custodians on what employees pay and what they can do with the money, then on how cleanly the account connects to your payroll and plan.
Fees are the easiest cost to overlook, because employees pay them, not you.
The employer usually sees the administrative fee. Employees see maintenance fees, investment fees and cash thresholds, often only after enrolling. We compare all of them side by side.
Account Fees
Monthly maintenance fees, who pays them, and what changes when an employee leaves. Some custodians shift the fee to the employee at termination, which quietly erodes small balances, so we price that scenario too.
Cash Threshold
Many custodians require a minimum cash balance before money can be invested. A high threshold keeps small and mid-size balances sitting in cash, which is why we compare it alongside the fund lineup.
Investment Options
Fund choices, expense ratios and whether an advisory tier adds its own fee. For employees treating the HSA as long-term savings, fund costs can matter more than any monthly fee.
Interest on Cash
Balances left in cash earn whatever rate the custodian sets. We compare those rates, because an employee who never invests earns only that rate, year after year.
The cheapest custodian is the wrong choice if contributions arrive late or wrong.
Payroll and employer contributions must reach the right account on time, every pay period. We test the operational side before we recommend anyone.
Payroll Funding
Contributions come from payroll every cycle. We check how the custodian receives that file and posts deposits, because a delay means a declined card at the pharmacy with money already withheld from the paycheck.
Contribution Limits
For 2026 the limit is $4,400 self-only and $8,750 family, counting employer deposits, plus $1,000 more for account holders 55 or older. We check how the custodian and payroll track totals, so employees are not left to unwind an excess contribution.
Card and Portal
The HSA card should work alongside any limited-purpose FSA or post-deductible HRA without confusing anyone. We check whether the custodian fits into a single card and portal or leaves employees carrying two.
Bundled is not wrong. It just has to win on its merits.
The carrier’s custodian can be the right answer. We make it earn the recommendation against the alternatives.
When Bundling Helps
Integration with the medical plan can let claims flow into the HSA portal and make paying bills simpler. For some workforces that convenience outweighs a fee difference, and when it does we say so.
When It Hurts
A bundled custodian may change when you change carriers, leaving employees to move accounts or hold two. We weigh how likely a carrier change is before tying the HSA to it.
Moving Custodians
Existing balances can be transferred, but each account holder has to act and exit fees may apply. We plan transfers so a move helps employees rather than scattering their savings across accounts.
What employers ask about HSA custodians.
Does the employer choose the custodian?
You choose where your payroll contributions go. Employees can move money to a custodian of their own, but the default you pick is where balances build unless someone acts, which is why the choice matters.
Is an HSA an ERISA plan?
HSAs are generally not treated as ERISA plans when employer involvement stays limited, and that limit shapes what you can require. Your counsel confirms where your arrangement falls.
What happens when an employee leaves?
The account stays theirs. Fees may shift to them at that point, which is why we look at post-employment fees when comparing custodians.
