Backdoor Roth IRA: Ultimate Fidelity Step by Step Guide

Hello, friends. We’re going to cover the Backdoor Roth IRA and why you should consider it.

I recently went through the process of doing a Backdoor Roth IRA using Fidelity. There are plenty of useful guides on the web already — many of which I’ll link to — but I didn’t find a guide for the layman.

I intend this to be that guide. I’ll walk you through what a Roth IRA is, what the Backdoor method is, how it’s done using Fidelity as a platform, and some tax considerations to look out for.

This guide is likely useful for the novice or intermediate investor. For folks looking for more detailed guidance, check out others on the web. Let me also state this guide is merely a suggestion. Make sure to consult your tax advisor or lawyer if you are unsure of your financial situation.

With that said, let’s dive in.

What is a Roth IRA?

First, let’s cover what a Roth IRA is so we have our bases covered.

A Roth IRA is a retirement account which takes in money already taxed (like your paycheck from work) and allows you to invest this to grow tax free. When you withdraw the money at an older age, it is also tax free.

This is a highly attractive account for those investing in their retirement, but there are some notable catches:

It has a limit on your income: $133,000 for individuals and $196,000 for couples. This rules out high-earning folks. It also includes a large majority of people living in high-cost (and high salaried) cities like San Francisco and New York. As wages continue to increase, the Backdoor Roth IRA will become an increasingly attractive way to save for retirement.

How Does it Differ from a Traditional IRA?

Where a Roth IRA takes in money already taxed (and it’s growth and withdrawals are free), a Traditional IRA takes in money tax free (through a deduction) and grows tax free, but the withdrawal is taxed (at your income level at the time of withdrawal, presumably in your older age).

The “input” to the Traditional IRA is attractive: you get to deduct your contribution from your income. For example, if you earn $100,000 for the year, and you contribute the maximum allowed of $5,500, then you are taxed like your income is $94,500 ($100,000 - $5,500). Another way to look at this is, say your federal and state income tax is a combined 38%, you’re saving over $2,000 by shielding away this $5,500 from the government (38% x $5,500).

Similar to the Roth, there are limitations:

  • If you have an employer retirement plan, you cannot deduct anything if your income is $72,000 or more filing as single or $119,000 filing as a couple. The IRS site has a more detailed breakdown.
  • If you do not have an employer retirement plan, you can deduct up to the $5,500 limit, regardless of your income.

The difference between the Roth IRA and Traditional IRA is simple: it boils down to whether you want to be taxed now or later. Translated another way: do you expect to make more money when you’re older? Most situations will be the latter — your earning potential goes up with age (higher salary, more income streams like rental properties, interest on investment accounts). If you think this is likely, the Roth IRA is probably the better bet. If you are taxed to hell now, and expect to earn less (or have your taxable income less in the future), the Traditional IRA may be the better choice. This is highly summarized however. We encourage you to research your ideal option.

This brings us back to the Backdoor Roth IRA. What is it?

The Backdoor Roth IRA

The Backdoor Roth IRA is a loop hole. There are income limits for the Roth IRA, and there are deduction limits for the Traditional IRA (assuming you have an employer retirement plan). Without the loophole, high-earning folks cannot take advantage of either. Enter the Backdoor Roth IRA.

Despite the limitations of both, there are (1) no limitations on non-tax-deductible contributions to the Traditional IRA, and (2) there are no limitations on converting a Traditional IRA to a Roth IRA.

So we’ll do the following process:

  • We’ll take our taxed money and put it into a Traditional IRA (there are no limits here because we can’t deduct it)
  • We’ll open a Roth IRA independent of the first point
  • We’ll convert our Traditional IRA to this Roth IRA
  • We’ll pay tax on any difference

Since we’re taking taxed money and having it end up in a Roth IRA, allowing it to grow tax free, we’ve effectively opened the Roth IRA despite the income limit.

Considerations before opening a Backdoor Roth IRA

Although there are no income limits to opening a Backdoor Roth IRA, you cannot already have tax-deferred money in an IRA (including Traditional IRA, SEP IRA, or SIMPLE IRA). This does not include 401(k), 403(b), or similar accounts.

If you do already have tax-deferred contributions in an IRA, you aren’t out of luck. There are two options:

  • Convert your tax-deferred contributions to the Roth and pay taxes: If the amount you have in your IRA account(s) is small, you can simply pay taxes on these when you roll them over to the Roth IRA.
  • Move the tax-deferred funds to an employer’s 401k account: Since 401(k), 403(b), and 457 retirement accounts are not affected, you can roll your tax-deferred IRA money to these accounts before your rollover.

An example from Boggle Heads:

For example, suppose you have just created a new traditional IRA, and you add $5,000 of non-deductible contributions to it. You'd like to convert this IRA to a Roth IRA via the backdoor.

Suppose you also have another traditional IRA with $15,000 in deductible pre-tax contributions. These contributions may have come from a 401(k) rollover, or from standard deductible traditional IRA contributions from earlier years when you were eligible to make deductible contributions to a traditional IRA.

To compute the tax due, you would need to take $5,000 and divide it by $20,000 (the total value of all your traditional IRAs), to get the percentage of the conversion that will be tax-free. In this case, it is 25%. Therefore, the other 75% of your conversion--in this case, $3,750--would be taxable.”

If you’re convinced the benefits of the Backdoor Roth IRA, let’s dive in and see how we can open do a Backdoor Roth IRA using Fidelity:

Step by Step Guide for Fidelity

Step 1

Open a Traditional IRA

  • Fund your account with your preferred method. Remember this is a normal retirement account at this point. We’re aiming to fund the max if you can of $5,500. You can do this a number of ways including a one-time transfer or a recurring transfer:

Step 2

Open a Roth IRA

Similar to opening a Traditional IRA, follow the steps to open a Roth IRA:

Step 3

This step is up to you. Some people think it's best to wait, say a month, before making the transfer. Others do it immediately. Either way is fine, although keep in mind: if you decide to wait and your Traditional IRA is invested in the market, it may increase in value, requiring you to pay a small tax on the growth. Look under the Taxes section for an example.

Step 4

Convert your Traditional IRA to a Roth IRA

Fidelity and some other providers like Vanguard allow you to do this online. Other may require you to call to convert the account. (If there is enough interest, I’ll likely post guides to other platforms for how to do this.)

  • Convert your Traditional IRA to a Roth IRA
  • Select the accounts you want to convert. In this case, it will be the new Traditional IRA account you created.

  • Elect to not have federal taxes withheld, although this is up to you. This gets settled up come tax time. Use the note below about taxes.


Of course, you’ll need to pay taxes come April 15th. If you have followed the guide, it shouldn't be too complicated.

If you waited to convert, you may owe a small amount of taxes. For example, when converting your Traditional IRA to a Roth IRA, if you put $5,500 in your Traditional IRA, waited a month, and the Traditional IRA grew to $5,623 due to interest — and then converted the entire $5,623 to the Roth — you’ll need to pay taxes on $123 dollars (since $5,500 is the limit).

There are better guides for taxes than what I can put here. The Finance Buff has great instructions for filing taxes for your Backdoor Roth on TurboTax, H&R Block, and Taxact.

In the future

In many cases, at the end of this, you’ll have a Traditional IRA with an account balance of zero, and your Roth IRA account. Fidelity and many brokers will leave this Traditional IRA account. Each year now, you can make your $5,500 contribution and roll it over the existing Roth IRA. Easy peazy.
