How To Set Up a Backdoor Roth IRA With Fidelity

Overview & The Pro-Rata Rule

In this step-by-step guide, I will walk through the steps to set up a Backdoor Roth IRA with Fidelity. If you don’t know the benefits of a Roth IRA, check out my post on Roth IRA vs 401(k) first. After reading it, you’ll know that performing a Backdoor IRA conversion is only useful if your 2026 income is above $153K (single) or $242K (married filing jointly).

Before proceeding, I advise you to consult a professional tax/financial advisor, as there may be hidden consequences to performing a Backdoor IRA.

For example, read about the pro-rata rule and how all your IRAs are treated as one aggregate account, which may trigger some unintentional tax consequences. If you don’t have any tax-deferred money in any existing IRAs or if you don’t have any IRAs at all, setting up a Backdoor IRA should be relatively straightforward.

Step-by-Step Backdoor Roth Conversion

There are several ways to set up a Backdoor IRA. But for the sake of simplicity, I will focus only on converting a Traditional IRA to a Roth IRA using cash (instead of assets).

Step 1: Open a Traditional IRA with Fidelity

Go to Fidelity Traditional IRA and follow the step-by-step guide to open an account.

A webpage promoting traditional IRA accounts, highlighting benefits such as no fees, tax-deferred earnings, investment options, and commission-free trades. There is an orange button labeled 'Open an IRA.'

Since this may be your first time using Fidelity, you will need to link a funding bank account before setting up a deposit.

a) Go to https://digital.fidelity.com/ftgw/digital/bank-setup.

Fidelity online banking page for linking a bank account, with options to select transfer type and account for linking.

b) Select which transfer type you’d like to use. I usually use electronic funds transfer (EFT) since banks usually have $0 fees. However, there’s a 1-3 business day settlement period for your cash to settle in your Traditional IRA. Wire transfers are faster but banks may charge a fee.

c) Select your newly-created Traditional IRA account to link your bank account to.

d) Fill out the remaining fields as requested by Fidelity.

Step 3: Fund Your Traditional IRA (Non-Deductible)

After linking your bank account, transfer your non-deductible contribution into your Traditional IRA. After you finish linking a bank account to your Traditional IRA, now it's time to make your first contribution.

a) Go to https://digital.fidelity.com/ftgw/digital/transfer/.

Online banking webpage with green header featuring Fidelity logo and 'Move money' option, a heading 'Let's start with the basics,' a question asking which account to move money from, a dropdown menu labeled 'From,' a blue 'Continue' button, and a 'Log Out' link in the top right corner.

b) Select which account to move money from. If you just linked a new bank account in Step 2, you’ll likely want to select that bank account. If you’re an existing Fidelity customer, it’s also possible to select another investment account like an individual Fidelity brokerage account that contains cash.

c) Next, select your Traditional IRA as the account the money should be transferred to. As I mentioned previously, you’ll notice that the estimated delivery time of the cash deposit is 1-3 business days.

d) For “Frequency,” select “Just once.”

e) Enter a “Date” you wish to transfer money from your bank into your account.

f) For “Amount,” you may contribute up to $7,500. If you’re 50 or older, you can contribute up to $8,600.

Note

These contribution limits are valid as of 2026 ($7,500 standard / $8,600 for age 50+).

Step 4: Wait for Cash Settlement (3–5 Business Days)

Wait 3-5 business days for your funds to settle. Personally, I prefer a “clean” conversion from a Traditional IRA to a Roth IRA. So every year that I perform a Backdoor IRA conversion, I wait for my funds in my Traditional IRA and do not invest a single dollar. I only invest after the Backdoor IRA conversion.

Step 5: Open a Roth IRA with Fidelity

Similar to Step 1, open a Roth IRA account. Don’t fund it directly — we are doing a Backdoor IRA conversion, so the funds will come from your Traditional IRA in the next step.

a) Go to Fidelity Roth IRA and follow their step-by-step guide.

Step 6: Execute the Backdoor Roth Conversion

To complete the conversion, transfer the settled cash from your Traditional IRA directly into your Roth IRA. Since settlement times vary, attempt this step after your deposit clears:

a) Go to Fidelity Transfers.

b) Select your Traditional IRA under "Transfer From".

c) Select your Roth IRA under "Transfer To" and complete the conversion.

Step 7: Invest Funds & File IRS Form 8606

Congratulations! That’s it. You’ve successfully set up a Backdoor Roth IRA. Remember to invest the cash inside your Roth IRA and file IRS Form 8606 at tax time.
