Best for: Optum Bank HSA
- Employees whose company uses Optum and pays the monthly and investment fees.
- Individuals who prefer to keep a large cash buffer for near-term medical expenses and can easily meet the $3,000 waiver.
- Those who value the integrated experience of having their HSA and health plan administration through a single provider.
Best for: Fidelity HSA
- Cost-conscious investors who want to avoid all account fees and invest their entire HSA balance immediately.
- Self-employed individuals or those with HSAs from previous employers seeking the lowest-cost custody option.
- Long-term planners using the HSA as a retirement vehicle, where fee minimization over decades is critical.
Pro Tips
- To avoid the $2.75 monthly fee, plan your cash buffer strategically. Keep exactly $3,000 (or your plan's threshold) in cash for the waiver, and invest every dollar above that to grow your long-term healthcare fund.
- If you're over 55, remember the $1,000 catch-up contribution. Spouses aged 55 or older must open their own separate HSA to each claim their catch-up, as it cannot be combined into a single family account.
- Before investing, confirm your specific plan's cash threshold. While $2,000 is common, some employer plans through Optum allow investment once you have just $500 in cash, letting you start investing sooner.
- Use online statements to avoid the $1.50 paper statement fee. Set up electronic delivery and download annual statements for your tax records to save money and reduce paper clutter.
- Time your HSA transfer. If you decide to move providers, consider doing it after you've met the cash balance fee waiver for the month to avoid being charged the maintenance fee during the transfer process.
- For self-employed individuals, your HSA contribution limit is based on the months you had qualifying HDHP coverage. You can make a full year's contribution if you had coverage on December 1st and maintain it for the following 13 months.
Frequently Asked Questions
What is the monthly maintenance fee for an Optum HSA and how can I avoid it?
Optum Bank charges a $2.75 monthly maintenance fee. You can have this fee waived if your average daily cash balance (not including invested funds) is $3,000 or more. It's important to check your specific plan documents, as some employer-sponsored plans may have a different waiver threshold, such as $2,000, or may have the fee covered entirely by your employer.
Does Optum Bank charge fees for investing my HSA money?
Yes, Optum charges an investment fee. There is a monthly investment fee of 0.03% of your average daily investment balance, which is capped at $10.00 per month. Annually, this works out to approximately 0.36%. Additionally, there is an annual $24.00 Investment Account Services Fee, unless your employer agrees to pay it. Optum does not charge trading fees for buying and selling investments within the HSA.
How much cash do I need to keep in my Optum HSA before I can start investing?
Typically, you must maintain a minimum cash balance of $2,000 in your HSA before you can invest any funds above that amount. The minimum transfer to invest is $100. However, fee schedules can vary by employer plan, and some list a lower investment threshold of $500. Always confirm the specific rule for your account by reviewing your plan materials or contacting Optum directly.
What happens if I contribute too much to my HSA?
The IRS imposes a penalty for excess HSA contributions. Any amount you contribute over the annual limit ($4,400 for individual or $8,750 for family coverage in 2026) is subject to ordinary income tax plus an additional 6% excise tax for each year the excess remains in the account. To avoid this, you should request a return of excess contributions from your HSA provider before the tax filing deadline.
Can I transfer my Optum HSA to another provider like Fidelity, and what does it cost?
Yes, you can perform a trustee-to-trustee transfer or a 60-day rollover to move your HSA to another custodian. Optum Bank charges a $20.00 fee for an outbound transfer or rollover to another HSA provider. Before initiating a transfer, contact your new provider for instructions to ensure the process is handled correctly and to potentially have them reimburse the transfer fee.
Are dental and vision expenses eligible for HSA reimbursement?
Yes, many dental and vision costs are eligible HSA expenses. This includes payments for dental treatments, orthodontia, eyeglasses, contact lenses, and eye exams. You can use your HSA funds tax-free for these qualified medical expenses, which helps families managing separate deductibles for health, dental, and vision plans. Always keep receipts in case of an IRS audit.
If I leave my job, what happens to my employer-sponsored Optum HSA?
Your HSA is your account, so you keep it even after leaving your job. However, your former employer will stop making contributions and may stop paying any associated fees. You will become responsible for the $2.75 monthly maintenance fee if your cash balance falls below the waiver threshold. You have the option to keep the account with Optum or transfer the funds to a new HSA provider of your choice.
