Backdoor Roth IRA: Advantages and Tax Implications Explained (2024)

What Is a Backdoor Roth IRA?

A backdoorRoth IRAis a strategy rather than an official type ofindividual retirement account. It is a technique used by high-income earners—who exceed Roth IRA income limits—to convert their traditional IRA to a Roth IRA.

The backdoor Roth IRA strategy is not a tax dodge. When you transfer the assets of a traditional IRA to a Roth IRA, you owe taxes on any funds—the principal, earnings, and appreciation—that have not been taxed previously.

If the IRA was funded solely with tax-deductible contributions, then the entire value of the transferred assets is taxed. As with any Roth IRA, you should owe no further taxes when you make withdrawals if you follow the rules.

Backdoor Roth IRA: Advantages and Tax Implications Explained (1)

Understanding Backdoor Roth IRAs

A Roth IRA allows taxpayersto set aside a few thousand dollars from their annual earnings in a retirement savings account. The contributed money is after-tax dollars—meaning the funds are earnings that have been taxed in the year when they are contributed to the Roth IRA.

Roth vs. Traditional IRAs

A Roth IRA differs from a traditional IRA. The traditional IRA gives the earner an immediate tax break because they can take a tax deduction for their contributions in the year they are made, and no taxes are due until the money is withdrawn. When withdrawals are made, usually after retirement, the account holder will owe taxes on both the dollars invested and their earnings.

How to Create a Backdoor Roth IRA

You can create a backdoor Roth IRAin one of three ways:

Contribute money to an existing traditional IRA and thenroll overthe funds to a Roth IRA. Or you can roll over existing traditional IRA money into a Roth—as much as you want at one time, even if it’s more than the annual contribution limit.
Convert your entire traditional IRA to a Roth IRA.
If your company 401(k) plan allows conversions, you can roll your 401(k) account over to a Roth IRA.

The custodial bank or brokerage for your IRA should be able to help you with the mechanics. If you have an employer-managed plan, you can contact the financial services firm that manages it to learn if your plan provides this opportunity.

Tax Implications of a Backdoor Roth IRA

Remember that in an IRA transfer or conversion to a Roth IRA,you still need to pay taxes on any money in your traditional IRA that hasn’t been taxed. For example, if you contribute $6,000 to a traditional IRA, claim a deduction for the $6,000 on your tax return, and then convert that money to a Roth IRA, you’ll owe taxes on the $6,000.

You’ll also owe taxes on whatever money that IRA contribution earned between the date when it was contributed to the traditional IRA and the date when you converted it to a Roth IRA. However, if you make after-tax contributions to a traditional IRA—that is, contribute funds that are nondeductible and taxable that year—these amounts will not be taxed on their transfer to the Roth IRA.

But if most of your IRA contributions were deducted from your income, and if your IRA has accumulated earnings or made investments that have appreciated over a long period, then most of the funds and investments that you convert to a Roth IRA likely will count as taxable income at the time of the conversion. That could kick you into a higher tax bracket that year; however, you may not have to pay tax on all the money; apro-ratarule applies to prevent taxing the amounts attributable to after-tax contributions.

Also, the funds that you put into the Roth are considered converted funds, not contributions. That means you must wait five years for penalty-free access to the funds in your backdoor Roth IRA if you’re under age 59½. These converted funds differ from regular Roth IRA contributions, which can be withdrawn anytime without taxes or penalties.

On the positive side, a backdoor Roth IRA lets you get around the income and contribution limits that apply to traditional Roth IRAs:

Roth IRA Income Limits: For 2023, if your MAGI is $153,000 ($161,000in 2024) or higher and you’re single, or $228,000 ($240,000 in 2024) or higher and you’re married filing jointly or a qualifying widow or widower, then you can’t contribute to a traditional Roth IRA.
Roth IRA Contribution Limits: For 2023, you can contribute $6,500 yearly (or $7,500 if you are 50 or older) to a Roth IRA. For 2024, you can contribute $7,000 yearly (or $8,000 if you are 50 or older).

With a backdoor Roth IRA conversion, these income and contribution limits don’t apply.

Benefits of a Backdoor Roth IRA

Aside from getting around the limits, why would taxpayers want to take the extra steps involved in doing the backdoor Roth IRA dance? There are several good reasons.

For one, Roth IRAs don’t haverequired minimum distributions (RMDs), which means that account balances can create tax-deferred growth for as long as the account holder is alive. You can take out as much or as little as you want, whenever you want, or you can leave it all for your heirs.

Another reason is that a backdoor Roth contribution can mean significant tax savings over decades because Roth IRA distributions, unlike traditional IRA distributions, are not taxable.

The main advantage of a backdoor Roth IRA—as with Roth IRAs in general—is that you pay taxes upfront on your converted pretax funds, and everything after that is tax-free. This tax benefit is greatest if you think that tax rates will rise in the future or that your taxable income will be higher in the years after your backdoor Roth IRA is established than it is now—especially if you plan to withdraw after a distant retirement date.

Is a Backdoor Roth Still Allowed?

Under the law, a backdoor Roth individual retirement account is legally permissible and respected by the IRS, provided that tax law requirements are met.

Is a Backdoor Roth a Good Idea?

The backdoor Roth strategy can be beneficial if you earn too much to contribute to a Roth IRA or if you've determined that a Roth IRA is better for your retirement.

Do You Pay Taxes Twice on a Backdoor Roth IRA?

Traditional IRA contributions are tax-deferred until withdrawals are taken. When you convert your IRA to a Roth IRA, you pay taxes on your contributions and capital gains. When you withdraw from your Roth, there are no taxes because you've already paid them. So you only pay taxes once using the backdoor Roth IRA strategy.

The Bottom Line

If you’re thinking of using the backdoor Roth IRA strategy, crunch the numbers and consider the tax implications, especially if you are converting the entire balance of a traditional IRA. Depending on how much money is in the account and what your income tax rate is, the amount of tax you owe could be huge.

Even given that, the backdoor Roth IRA strategy can have advantages—especially for high earners. Roth IRAs don’t have RMDs, so you can hold them forever and pass them on to your heirs. Another advantage is that a backdoor Roth contribution can mean significant tax savings over the decades because Roth IRA distributions, unlike traditional IRA distributions, are not taxable.
