Pro Tips

  • When setting up payroll, provide both the routing number 101205681 and the full account number with the correct prefix (39900000 or 39900001). Many payroll systems reject the submission if the account number is missing digits, causing contribution delays.
  • If mailing a check, write the tax year (e.g., '2026 Contribution') in the memo line along with your account number. This helps Fidelity correctly allocate the funds for that year's tax reporting, preventing end-of-year reconciliation headaches.
  • Monitor your combined contribution total (yours and your employer's) in your Fidelity account dashboard. Exceeding the IRS limit can trigger a 6% excise tax, and correcting it requires filing additional forms.
  • Consider automating monthly bank transfers to your Fidelity HSA using the routing number if your employer doesn't offer payroll deductions. This builds your balance consistently and can be invested once it exceeds your chosen cash cushion.
  • For audit protection, use your Fidelity HSA debit card for all eligible medical purchases. The transaction memo field often auto-populates with the merchant name (like 'DENTIST'), creating a clear, searchable record for the IRS.

Quick Answers

What is the Fidelity HSA routing number for direct deposits?

The Fidelity HSA routing number for deposits is 101205681. This number is used exclusively for initiating deposits into your Fidelity HSA via ACH transfers, including payroll direct deposit and bank transfers. It is important to note that this routing number is not for spending or debit card transactions. For those functions, you would use your Fidelity HSA debit card or checkwriting features linked to your specific account.

How do I find my full Fidelity HSA account number for direct deposit setup?

Your full account number for direct deposit is not just your brokerage account number. Fidelity requires a specific prefix. For personal HSA contributions via bank transfer, use the prefix 39900000 followed by your 9-digit Fidelity brokerage account number. If you are setting up payroll deductions through your employer, you may need to use the prefix 39900001 followed by your account number.

Can I use my Fidelity HSA routing number for bill pay or spending?

No, you cannot use the Fidelity HSA routing number 101205681 for spending or bill pay. This routing number is designated only for depositing funds into your HSA. To spend from your HSA, you should use your Fidelity HSA debit card for eligible expenses, write a check from your HSA checkbook if you have one, or initiate a transfer from your HSA to your linked bank account. Treating the deposit routing number as a checking account for withdrawals will result in failed transactions.

What are the different ways I can contribute money to my Fidelity HSA?

Fidelity provides five primary methods to contribute to your HSA. You can do a bank transfer (ACH) using the routing and account numbers, make a mobile check deposit through the Fidelity app, transfer funds from an existing HSA at another provider, make a one-time contribution from an IRA (subject to IRS rules), or mail a check to Fidelity Investments, P.O. Box 770001, Cincinnati, OH 45277-0047. For mailed checks, you must write your account number and the applicable tax year in the memo line.

Does Fidelity charge any fees for having an HSA?

Fidelity charges no opening or maintenance fees for its standard Fidelity HSA or its managed Fidelity Go HSA. This makes it a popular choice for individuals looking to avoid the monthly fees common with some other providers. For the Fidelity Go HSA, which provides automated investment management, there is a minimum balance of $10 to begin investing. Always review the latest fee schedule on Fidelity's website for any potential transaction-specific fees.

Who should I call if I have questions about my Fidelity HSA or debit card?

For general questions about your Fidelity HSA, including contributions, transfers, and account setup, you can call 800-544-3716. If you are experiencing issues specifically with your Fidelity HSA debit card, such as a lost card, a declined transaction, or a PIN reset, you should contact the dedicated debit card service line at 888-377-0323. Having your account number ready will help expedite service.

How are my HSA contributions reported on my taxes?

HSA contributions have specific tax reporting. Pre-tax contributions made through your employer's payroll are reported in Box 12 of your Form W-2, using Code W. This amount is not included in your Box 1 wages. Contributions you make directly to Fidelity (post-tax) must be reported on your personal tax return (Form 8889) to claim the above-the-line deduction. It is your responsibility to track all contributions, as the IRS combines employer and employee contributions for the annual limit.
