Fidelity HSA Routing Number
Account Funding & TransfersSetting up direct deposit or a bank transfer into your Fidelity HSA requires a specific nine-digit code. The correct Fidelity HSA routing number is 101205681, but using it correctly is not always straightforward. Many W2 employees and self-employed individuals face confusion when their payroll department asks for this information, leading to delays in funding their tax-advantaged accounts. This guide explains exactly when and how to use this number, the critical difference between deposits and spending, and how to avoid common mistakes that could trigger IRS contribution limit issues or leave your account unfunded when you need it for medical expenses.
Fidelity HSA Routing Number
The unique nine-digit code, 101205681, assigned to Fidelity Investments for processing electronic deposits into a Fidelity Health Savings Account.
In Context
For W2 employees with HDHPs, this number is required to set up pre-tax payroll deductions. For self-employed individuals, it is used for making after-tax contributions that will be deducted on their tax return.
Example
An HR benefits manager setting up direct deposit for an employee would enter routing number 101205681 and the employee's Fidelity HSA account number (e.g., 39900000123456789) into the payroll system.
Why It Matters
Knowing the correct Fidelity HSA routing number matters because a simple error can prevent your money from reaching its tax-advantaged destination. For a family maximizing their HSA for healthcare and retirement, a missed payroll deposit could mean losing out on pre-tax savings and employer matching funds.
Common Misconceptions
- A common mistake is thinking the Fidelity HSA routing number can be used for all transactions, including paying providers or withdrawing funds. It is exclusively for inbound deposits.
- Many people believe their standard Fidelity account number is sufficient for direct deposit. You often need to add the 39900000 prefix, and using the number without it will likely cause the deposit to fail or be rejected.
Practical Implications
- You must provide the exact routing number 101205681 and your formatted account number to your employer's payroll department to enable pre-tax contributions, which are reported in Box 12, Code W of your W-2.
- When performing a transfer from another HSA provider or your personal bank, you will need this routing number to identify Fidelity as the receiving institution for the ACH network.
- Understanding that this number is for deposits only clarifies that managing and spending from your HSA is a separate process, typically handled through your account's debit card, checks, or online bill pay features.

Pro Tips
When setting up payroll, give your HR department both the routing number (101205681) and your full account number with the 39900000 or 39900001 prefix. Follow up after the first pay cycle to confirm the deposit hit your account.
If you mail a check, write your Fidelity account number and the applicable tax year (e.g., '2025 HSA Contribution') in the memo line. Send it to Fidelity Investments, P.O. Box 770001, Cincinnati, OH 45277-0047 to avoid processing delays.
Treat your HSA like a retirement account. Once your balance exceeds your expected near-term medical costs, consider investing a portion. The Fidelity Go HSA requires only a $10 minimum to start automated investing.
Keep a separate record of all contributions, including payroll slips and bank transfer confirmations. This makes it easier to verify the Box 12, Code W amount on your W-2 and track your progress toward the IRS limit.
If you have an HSA with a high-fee provider, you can open a Fidelity HSA and do a direct trustee-to-trustee transfer. You cannot, however, transfer funds from a Flexible Spending Account (FSA) into an HSA.
Frequently Asked Questions
What is the Fidelity HSA routing number?
The official Fidelity HSA routing number is 101205681. This number is specifically used for electronic deposits into your Health Savings Account, such as direct deposits from your employer's payroll system, transfers from your personal bank account, or rollovers from another HSA provider. It is not used for debit card transactions or bill payments from the account. You must pair it with your correctly formatted Fidelity account number for the transfer to succeed.
How do I find my Fidelity HSA account number for direct deposit?
Your Fidelity HSA account number for direct deposit is not the simple number on your statement. For personal accounts, you typically use the prefix 39900000 followed by your 9-digit Fidelity brokerage account number. If you are setting up payroll deductions through your workplace, you may need to use the prefix 39900001 instead. You can find your base account number on your Fidelity statements or by logging into your account online.
Can I use the Fidelity HSA routing number to pay medical bills?
No, you cannot use the routing number 101205681 to pay bills directly from your HSA. This routing number is for incoming deposits only. To pay for eligible medical expenses, you should use your Fidelity HSA debit card, write a check from the account if you have that feature enabled, or initiate a reimbursement transfer from your HSA to your personal bank account after paying out-of-pocket. Using the deposit routing number for spending will not work and may cause payment failures.
What are the different ways to contribute money to my Fidelity HSA?
Fidelity provides five main methods to add funds. You can do an electronic bank transfer (ACH) using the routing and account numbers, make a mobile check deposit via the Fidelity app, initiate a transfer or rollover from another HSA provider, make a one-time contribution from an IRA (a qualified funding distribution), or mail a physical check to Fidelity Investments, P.O. Box 770001, Cincinnati, OH 45277-0047.
Are there any fees for having a Fidelity HSA?
Fidelity charges no opening or maintenance fees for its standard HSA or its Fidelity Go HSA, which is a managed account option. This is a major benefit for account holders who want to avoid costs eroding their healthcare savings. The Fidelity Go HSA does have a minimum balance of $10 to begin its automated investment management. Always confirm the latest fee schedule directly with Fidelity, as provider policies can change, but the no-fee structure is a key selling point.
Who should I call if I have issues with 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 problems specifically with your HSA debit card, such as a lost card, declined transactions, or PIN issues, you should call the dedicated number at 888-377-0323. Having the correct contact information saves time and helps resolve issues faster, especially around tax time or when you have an urgent medical expense.
How are my HSA contributions reported on my taxes?
If you contribute through payroll deduction, your pre-tax contributions will appear in Box 12 of your Form W-2 with the code W. This amount is not included in your taxable wages in Box 1. It is your responsibility, along with your employer, to ensure that total contributions from all sources (your payroll, any after-tax contributions you make, and any employer contributions) do not exceed the annual IRS limits. Keeping track of this is vital to avoid excess contribution penalties.
