A backdoor Roth IRA is a strategy rather than an official type of individual retirement account. It is a technique used by high-income earners—who exceed Roth IRA income limits for making contributions—to contribute indirectly–through the back door–by converting 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 as well as any 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.
A Roth IRA allows taxpayers to 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.
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can take a tax deduction for their contributions in the year they are made, and no taxes are due until the money is withdrawn.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.
The problem for high-income taxpayers is that individuals who earn above a certain amount aren’t allowed to open or fund Roth IRAs. If your modified adjusted gross income (MAGI) exceeds statutory ceilings, then the the amount that you can contribute starts to decline until you cannot participate at all. The phaseout limits, as they are known, are as follows:
Traditional IRAs don’t have income ceilings for participation. And, since 2010, the Internal Revenue Service (IRS) hasn’t had income limits that restrict who can convert a traditional IRA to a Roth IRA. As a result, the backdoor Roth IRA has become a tax-planning opportunity for higher-income taxpayers who ordinarily couldn’t contribute to a Roth IRA.
The way that backdoor Roth IRAs work has changed over the years. Although IRA funds that were transferred to Roth IRAs in pre-2018 conversions could be recharacterized as traditional IRA contributions before 2018, the Tax Cuts and Jobs Act (TCJA) of 2017 banned the strategy of recharacterizing converted funds in a Roth IRA back to a traditional IRA contribution in conversions enacted after Dec. 31, 2017.
Some taxpayers who are ineligible to deduct IRA contributions use after-tax dollars to fund a traditional IRA and pay taxes again when withdrawing from the account just to have an 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.

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; a pro-rata rule 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:
With a backdoor Roth IRA conversion, these income and contribution limits don’t apply.
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 have required 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. After that, you can withdraw money tax-free, including earnings and new deposits once they qualify. 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.
The Retirement Security Rule, also known as the fiduciary rule, aims to protect investors from conflicts of interest when receiving investment advice that the investor uses for retirement savings.
The rule was issued by the U.S. Department of Labor (DOL) on April 23, 2024. It takes effect on September 23, 2024. Further, the effective date of certain conditions will be delayed to 2025.
The rule will impact people saving and investing for retirement who use an advisor who acts as a fiduciary under the Employee Retirement Income Security Act (ERISA). Those advisors are subject to the higher standard–the fiduciary best-advice standard rather than the lower, merely suitable advice standard. Their designation can limit products and services they are allowed to sell to clients who are saving for retirement.
Under the law, a backdoor Roth individual retirement account is legally permissible and respected by the IRS, provided that tax law requirements are met.
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.
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.
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.
