Income Eligibility Requirements for a Roth IRA
A "Backdoor Roth" Allows High Earners to Qualify for a Roth IRA
If your income level exceeds the allowable amount to qualify for a Roth IRA, you can use the backdoor Roth strategy if a Roth IRA is appropriate for you. You would make a nondeductible contribution for the maximum allowable amount into a Traditional IRA ($7,000 if you’re younger than 50, $8,000 if you’re 50 or older). Then you would convert your Traditional IRA into a Roth IRA. This is generally a taxable event in which you pay ordinary income tax on the amount you convert into the Roth IRA, but all earnings and growth in the Roth IRA after the conversion will be tax-free after they’ve been in the account for five years. In addition, Roth IRA owners aren’t subject to required minimum distributions (RMDs), but their beneficiaries who inherit the Roth IRA will be required to take RMDs.
High-income earners who have traditional IRAs, SEP IRAs, and/or SIMPLE IRAs from a previous employer can also convert these accounts to Roth IRAs. You’ll want to discuss this with your tax professional to see if you want to spread the conversion out over multiple years to avoid a large tax liability in a single year, especially if the conversion could bump you into a higher tax bracket.
A "Mega Backdoor Roth" Allows High Earners to Maximize Retirement Plan Contributions
Another little-known strategy allows high earners to use after-tax contributions to a 401(k) to fund a Roth IRA. It’s called a mega backdoor Roth because the dollar amounts involved are typically large.
Example: A 50-Year Old Employee Contributes the Maximum to a 401(k)
How can this individual reach the $76,500 limit for 2024 for employees 50 or older?
The employee can make after-tax contributions to contribute an additional $28,500
Why would someone want to do this?
High-income individuals who otherwise aren't eligible for a Roth IRA can rollover the after-tax contributions they make in a 401(k) into a Roth IRA.
How does it work?
Call your 401(k) provider and ask if your plan allows after-tax contributions. If it does, ask if the plan permits you to rollover your after-tax contributions into a Roth IRA (i.e., in-service withdrawals or in-plan conversions). More than 70% of 401(k) plans allow in-service withdrawals,1 so it’s likely your plan offers this feature.
More than 70% of plans allow in-service withdrawals according to a survey by the Profit Sharing Council of America.
You would then increase your 401(k) contributions so that when your pre-tax contributions are exhausted, all additional contributions would fund your after-tax sources until you hit the maximum allowable limit. Once you have a sufficient amount in after-tax sources, you could roll the after-tax dollars into a Roth IRA.
If you’ve been making after-tax contributions for years and haven’t made any in-service withdrawals, you may have a sizable amount in your after-tax sources. If you choose to roll all or part of this money over to a Roth IRA, the IRS requires your withdrawal to be a combination of your after-tax contributions and the earnings on those contributions.
In fact, your 401(k) provider will likely mail you two separate checks—one for the after-tax contributions and a second one for the after-tax earnings on those contributions. After-tax contributions can be rolled over to a Roth IRA tax-free as long as the check is made payable directly to the firm to which you’re rolling over the assets. After-tax earnings can be rolled over to a Traditional IRA tax-free. If you want to move your after-tax earnings into a Roth IRA, that would be a taxable event.
The calendar year after your IRA rollover takes place, your 401(k) provider will report the rollover on Form 1099R in January, and the firm that receives the IRA rollover will report it on Form 5498 by May 31. These tax forms are generated for reporting purposes only.
Who would this strategy be appropriate for?
This strategy may be appropriate for you if your income is high and you’ve already funded your retirement plans, IRAs, and HSAs with the maximum dollar amounts. Once this occurs, you can either invest additional dollars through a nonqualified account if you think you’ll need access to your money prior to age 59½, or you can use the mega back door Roth conversion strategy if you’re ready to earmark the money for retirement.
If you decide to implement this strategy, you should consider doing an annual rollover of your after-tax contributions into a Roth IRA to help limit the amount of earnings on your after-tax contributions that will eventually be subject to tax.
Roth 401(k) Contributions vs. After-Tax Contributions
The Roth component of a 401(k) is available to individuals of all income levels. Roth contributions are funded with after-tax contributions and the earnings compound tax-free. When you ultimately withdraw money from a Roth 401(k), the distributions are generally tax-free once you’ve held the account for five years or attained age 59½ (whichever of these events is later). Penalty-free withdrawals are permitted if an individual dies or becomes permanently disabled. Unlike Roth IRAs, Roth 401(k)s are subject to RMDs, but the withdrawals are tax-free.
Like the Roth 401(k), after-tax contributions within a 401(k) are funded with after-tax dollars. But while Roth contributions compound tax-free, earnings on after-tax contributions compound tax-deferred. Withdrawals of after-tax contributions are tax-free after age 59½, while withdrawals of the earnings on those contributions would be taxable.
Given the significant advantages of a Roth 401(k), investors typically choose to maximize their contributions to a Roth 401(k) before opting to make after-tax contributions to their 401(k).
