Backdoor Roth IRA Guide (2024)

Making direct contributions to a Roth IRA is off-limits for people with high annual incomes. If your earnings put Roth contributions out of reach, a backdoor Roth IRA conversion could be a great way to benefit from the tax advantages of the Roth IRA.

What Is a Backdoor Roth IRA?

A backdoor Roth IRA isn’t a special type of account. Rather, it’s a strategy that helps you move money into a Roth IRA even though your annual income would otherwise disqualify you from making direct contributions.

The table below lists the annual income thresholds that limit Roth IRA contributions. The backdoor Roth IRA strategy lets you circumvent these limits, although it does involve making additional tax payments.

How Does a Backdoor Roth IRA Work?

Here’s how it works. Open a new traditional IRA, make non-deductible contributions and then convert the account into a Roth IRA. There are no income thresholds limiting who can make nondeductible IRA contributions, although you still need to obey the annual IRA contribution limits.

Anyone can convert traditional IRAs to Roth IRAs, regardless of annual income. However, a backdoor Roth IRA is most useful to high earners with access to a workplace retirement plan that makes them ineligible to deduct their traditional IRA contributions in the first place.

You can also do a backdoor Roth IRA by converting deductible contributions held in a traditional IRA or a traditional 401(k) to a Roth IRA. However, you will probably owe taxes on the money you convert.

Guide to Backdoor Roth IRA Conversions

To complete a backdoor Roth IRA conversion, you must proceed methodically to avoid extra penalties or taxes. Closely follow these three steps:

Step 1: Open and Fund a Traditional IRA

Start by opening a new traditional IRA. If you already have a traditional IRA, there’s no reason you can’t use it for a backdoor Roth IRA conversion, but remember that the funds you have saved in it may impact the amount you owe in taxes. That’s because of the IRA aggregation and pro-rata rules, which we’ll discuss later.

When you fund a new traditional IRA, the key is to make non-deductible contributions (i.e., the money you’ve already paid taxes on and won’t seek a deduction for). In addition, you must file IRS Form 8606 listing your non-deductible contributions.

Step 2: Understand How a Roth IRA Conversion Works

Check with your IRA providers about the required paperwork for a Roth IRA conversion. The process may be a relatively simple same-trustee transfer if your traditional IRA and Roth IRA are with the same account provider.

If you have separate providers for each IRA, a trustee-to-trustee transfer—where one company wires the money to another—shouldn’t be complicated.

If your IRA provider won’t manage the transfer of funds and hands you a check, you can still do a backdoor Roth IRA. But you must deposit the check in a new Roth IRA account within 60 days. Otherwise, it may be considered an early withdrawal, with potential taxes and penalties.

Step 3: Convert Your Traditional IRA to a Roth IRA

Immediately convert your new traditional IRA to a Roth IRA. Doing the conversion as soon as possible prevents the non-deductible contributions you put in your new traditional IRA from accumulating investment gains, which would mean you’d owe tax on these gains when you made the Roth IRA conversion.

That said, there’s no time limit on when you can convert a traditional IRA to a Roth IRA. You could wait until later in a given year to see how your balance settles if you had existing funds in an old traditional IRA and wanted to minimize potential taxable gains.

How to Start a Backdoor Roth IRA Conversion

Most brokerages can help you handle a Roth IRA conversion, especially if you opened your traditional IRA with them. If you’re opening a traditional IRA for the first time, choose a brokerage that offers traditional and Roth IRA options that meet your needs.

For 2024, you can contribute up to $7,000 ($8,000 if you’re 50 or older) to your traditional IRAs and Roth IRAs. Previously, the limit on contributions to an IRA was limited to $6,500 and up to $7,500 for those age 50 and older.

To minimize the tax risks of a backdoor Roth IRA, make your annual contribution as a lump sum and then immediately perform the Roth conversion.

Special Considerations for a Backdoor Roth IRA

When attempting a backdoor Roth IRA conversion, you need to be aware of the quirks of IRAs and some special tax considerations.

There Are Two Five-Year Rules for Backdoor Roth IRAs

The five-year rule states that in most cases—even if you’re over 59 ½—you generally cannot withdraw Roth IRA earnings free of taxes (and often penalties) unless your first contribution to a Roth account was made at least five years ago. You’re usually allowed to withdraw contributions from your Roth IRA at any time, free of penalties or taxes.

There is a second five-year rule, however, for backdoor Roth conversions. Because a backdoor Roth IRA is categorized as a conversion—not a contribution—you cannot access any of the funds held in the converted Roth IRA without penalty for the first five years after conversion.

If you do a backdoor Roth IRA conversion every year, you must wait five years to tap each portion you convert. Otherwise, you risk paying additional penalties on money that’s already been taxed. There are exceptions to this requirement, though, if you’re 59 ½ or older or if you become disabled or die.

Traditional IRAs That Hold Previously Deducted Contributions

The IRS views all of your traditional IRAs as a single account when determining the taxes you owe on distributions. Unfortunately, from the IRS’s standpoint, “distributions” include Roth IRA conversions. This fact greatly complicates backdoor Roth IRA conversions for people who already hold existing balances in traditional IRAs.

In practice, this means you may owe taxes on the money you intend for a backdoor Roth IRA conversion—even if the money has already been taxed. This happens when the IRS’ aggregation rule intersects with the pro-rata rule.

The pro-rata rule states that once money enters an IRA, you cannot separate the portion that’s already been taxed from the portion that was deducted from taxes. You may hear this described as the “cream in your coffee” rule. Once cream hits the coffee, separating it from the dairy is impossible. The same goes for your pre-tax and post-tax IRA contributions.

Let’s say 80% of the funds in your combined IRAs earned tax deductions, and 20% did not. When you undertake a backdoor Roth IRA conversion, you can’t separate the already taxed funds for conversion, much like the cream cannot be separated from the coffee. In this example, 80% of the money being converted to a Roth IRA would be taxed in a Roth IRA conversion.

If you’re considering a backdoor Roth conversion, speak with a financial advisor to help you manage the process to minimize the amount of taxes you may owe. It could make sense to roll over some of your money into a 401(k), which is not considered in pro-rata calculations.

Some States Tax Backdoor Roth IRA Conversions

Most states that charge income taxes treat a backdoor Roth conversion in the same way as federal tax law. But some states will exempt some part of a pension or IRA distribution from taxes if the person is over a certain age.

Some states may exclude the entire conversion amount from tax, and states without an income tax law also don’t tax any conversion amounts.Sitting down with a tax professional can help you navigate any state or federal taxes your backdoor Roth may incur.

What About a Rollover 401(k) to Roth IRA?

You can also access a backdoor Roth IRA by rolling over a traditional 401(k) into a Roth IRA. Unlike a backdoor Roth, you will probably owe some kind of income tax on the money you convert unless you made nondeductible contributions to your traditional 401(k).

Should You Consider a Backdoor Roth IRA?

Deciding whether a backdoor Roth IRA is the right move for you depends on your situation. Carefully consider the implications before moving forward.

Who Could Benefit from a Backdoor Roth IRA?

• High earners who don’t qualify to contribute under current Roth IRA rules.
• People who can afford the additional taxes involved in a Roth conversion and want to take advantage of future tax-free growth.
• Retirees who want to avoid required minimum distributions (RMDs).

Who Might Not Benefit from a Backdoor Roth

• People whose annual income makes them eligible for regular Roth IRA contributions.
• Investors who will need to use Roth IRA funds within five years. The five-year rule applies to Roth conversions, so there could be a penalty for those under age 59½ who need to access converted funds during those first five years.
• Those with other traditional IRAs that create a situation under the aggregate and pro-rata rules that could complicate matters to the point that the tax consequences outweigh the benefits.

Talk with a financial advisor if you have substantial funds in a traditional IRA or are unsure how to manage your backdoor Roth IRA strategy.
