Our Verdict

Best for: HSA Bank
- Employees whose company-sponsored HSA is through HSA Bank for easiest payroll setup.
- Users who prioritize a banking-centric interface with strong bill pay features for medical expenses.
- Those who are comfortable maintaining a minimum cash balance to waive account fees.
Best for: Fidelity
- Self-employed individuals and investors wanting a no-fee account with full brokerage integration.
- Anyone looking to invest their entire HSA balance immediately without a cash threshold.
- People consolidating multiple HSAs or retirement accounts who prefer Fidelity's ecosystem.
- Cost-conscious savers who want to avoid all monthly maintenance and investment fees.
Pro Tips
- Treat your HSA as a retirement account first. Pay current medical bills out-of-pocket if possible, and let your HSA funds grow invested for decades, creating a tax-free pool for healthcare in retirement.
- If your employer contributes to your HSA, always contribute enough to get the full match first. This is free money that immediately boosts your savings, similar to a 401(k) match.
- Keep digital copies of all medical receipts and invoices. You can reimburse yourself from your HSA for any eligible expense at any time in the future, even years later, allowing your money more time to grow.
- Use the 'last-month rule' with caution. If you are eligible on December 1, 2026, you can make the full year's contribution, but you must maintain HDHP coverage for the entire testing period (through December 31, 2027) or face penalties.
- Review your HSA investment options annually. Many default to low-interest cash accounts. Actively choose a diversified portfolio of low-cost index funds to maximize long-term growth potential.
Frequently Asked Questions
What is the maximum I can contribute to my HSA in 2026?
For the 2026 tax year, the IRS set the contribution limits at $4,400 for self-only HDHP coverage and $8,750 for family coverage. If you are 55 or older and not enrolled in Medicare, you can add a $1,000 catch-up contribution. This makes the maximum total $5,400 for self-only or $10,750 for family coverage. These limits are federal and apply regardless of which provider, like HSA Bank or Fidelity, holds your account.
Can I have an HSA if my employer uses HSA Bank?
Yes, if your employer sponsors an HSA through HSA Bank, you are enrolled in that specific account. However, you are not locked in. You can open a second HSA bank account with another provider, like Fidelity, and perform a trustee-to-trustee transfer to move funds. You cannot make duplicate contributions across accounts; the annual limit applies to the sum of all your HSAs. Many people transfer funds periodically to consolidate accounts with better investment options or lower fees.
What expenses are eligible for HSA reimbursement in 2026?
Eligible expenses include a wide array of medical, dental, and vision costs not covered by insurance. This encompasses deductibles, copays, prescriptions, dental cleanings, eyeglasses, contact lens solution, and many over-the-counter medications without a prescription. Mental health therapy, addiction treatment, and certain fitness expenses like costs related to weight loss programs for a specific disease are also eligible.
What happens to my HSA if I leave my job or change health plans?
Your HSA bank account is yours forever, similar to an IRA. If you leave your job, you keep the account and all funds. If you switch to a health plan that is not a qualified HDHP, you can no longer make new contributions, but you can still use the existing funds for eligible expenses. You can also continue to invest the money already in the account. This portability is a key advantage over Flexible Spending Accounts (FSAs).
How do I avoid monthly fees on my HSA?
Fees vary by provider. HSA Bank often waives its monthly maintenance fee if you maintain a minimum cash balance, typically $3,000 or $5,000. Fidelity generally charges no monthly fees regardless of balance. To avoid fees, review your provider's fee schedule carefully. If fees are eating into your savings, consider switching to a no-fee provider or ensuring you meet the minimum balance requirement. Even small monthly fees can significantly reduce long-term investment growth.
Can I invest the money in my HSA bank account?
Yes, most HSA providers allow you to invest a portion of your balance once it exceeds a cash threshold, often $1,000 or $2,000. HSA Bank typically offers a linked TD Ameritrade investment account with access to mutual funds and ETFs. Fidelity integrates investments directly into its HSA platform, offering a full brokerage experience. Investing is a powerful strategy for growing your HSA for future healthcare costs in retirement, as all growth is tax-free when used for qualified expenses.
What is the deadline to contribute to an HSA for the 2026 tax year?
You have until the federal tax filing deadline of April 15, 2027, to make contributions designated for the 2026 tax year. This gives you extra time to calculate your total medical expenses and maximize your tax deduction. Ensure your contribution is correctly coded for the correct tax year by your provider. Making a prior-year contribution is a common strategy for last-minute tax planning.
