Backdoor Roth IRAs for Beginners

If you read enough FI blogs, you will eventually come across the term “Backdoor Roth IRA.” This post answers the question “What’s the deal with Backdoor Roth IRAs?”

Why Do a Backdoor Roth IRA?

Why would someone do a Backdoor Roth IRA? The Backdoor Roth IRA gets money into a Roth IRA in cases where the taxpayer earns too much to make a direct annual contribution to a Roth IRA. Doing the Backdoor Roth IRA gets money that would have been invested in a taxable account into a tax-free Roth account. Further, the money in the Roth account gets better creditor protection than money in a taxable account.

History of the Backdoor Roth IRA

Before 2010, what is now referred to as a Backdoor Roth IRA would have been permissible and/or necessary in only relatively limited circumstances, and then only in years prior to 2008. But a 2006 change in the law opened up the Backdoor Roth IRA in the form we know now (starting in 2010).

Two fundamental concepts must now be addressed. The first is a Roth IRA contribution.

Roth IRA Contributions

This post discusses Roth IRA contributions in detail. Simplified, U.S. citizens and residents with earned income can make an annual Roth IRA contribution of up to $7,000 in 2024 ($8,000 if 50 or older). Done for many years, it can be a tremendous wealth building tool, since it moves wealth into an account that is tax-free (if properly executed).

The one catch is that your “modified adjusted gross income” (or “MAGI”) must be below a certain threshold in order to make a Roth IRA contribution. To make a full contribution in 2024, your MAGI must be less than $146,000 (if single) or $230,000 (if married filing joint).

Because of these limits, many taxpayers are unable to make a Roth IRA contribution. Further, based on the qualification rules for traditional deductible IRA contributions, most taxpayers unable to make a Roth IRA contribution are also unable to make a deductible traditional IRA contribution.

Roth IRA Conversions

The second fundamental concept is a Roth IRA conversion. A Roth IRA conversion is a movement of amounts in traditional accounts to a Roth IRA. This creates a taxable event. The amount of the Roth IRA conversion, less any “basis” in the traditional account (more on that later), is taxable as ordinary income on the taxpayer’s tax return.

Prior to 2010, only taxpayers with a modified adjusted gross income of $100,000 or less were allowed to do a Roth IRA conversion. This amount was not indexed for inflation and applied per tax return, making it particularly difficult for many married couples to qualify.

In 2006, Congress changed the law, effective beginning in 2010. As of January 1, 2010, there is no modified adjusted gross income limitation on the ability to do a Roth IRA conversion. The richest, highest earning Americans now qualify to do a Roth IRA conversion just as easily as anyone else.

The Backdoor

Okay, so there’s no MAGI limitation on the ability to execute a Roth IRA conversion. So what? Aren’t they taxable? What’s the advantage of doing one?

Recall I mentioned a taxpayer’s basis in a traditional account. Basis in an IRA occurs when a taxpayer makes a nondeductible contribution to a traditional IRA. Here is an example.

Mike expects to earn $300,000 from his W-2 job in 2024, is covered by a workplace 401(k) plan, and expects to have some investment income. Mike has no balance in a traditional IRA, SEP IRA, or SIMPLE IRA.

Mike contributes $7,000 to a traditional IRA on April 20, 2024. The contribution is nondeductible. Because the contribution is nondeductible, Mike gets a $7,000 basis in his traditional IRA. Mike must file a Form 8606 with his 2024 tax return to report the nondeductible contribution.

The “backdoor” opens because of the confluence of two rules: the ability to make a nondeductible traditional IRA contribution and the ability to do a Roth IRA conversion regardless of your income level. Let’s extend Mike’s example a bit.

On May 2, 2024, Mike converts all the money in his traditional IRA to a Roth IRA (a Roth IRA conversion). At that time, Mike’s traditional IRA had a value of $7,011.47.

What result? To start, all $7,011.47 is taxable. All money converted in a Roth IRA conversion is taxable. Uh oh! But there’s good news for Mike. Mike gets to offset the $7,011.47 that is taxable by the $7,000 of basis in his traditional IRA. Thus, this Roth IRA conversion will only increase Mike’s taxable income by $11.47 ($7,011.47 minus $7,000).

The combination of these two separate, independent steps (a nondeductible traditional IRA contribution and a later Roth IRA conversion) is what many now refer to as the Backdoor Roth IRA. Notice this is only possible because of the repeal of the MAGI limitation on Roth IRA conversions. Under the rules effective prior to 2010, Mike would have been allowed to make the nondeductible traditional IRA contribution, but his income (north of $300,000) would have prohibited him from a Roth IRA conversion.

The Backdoor Roth IRA allows Mike to obtain the benefits of an annual Roth IRA contribution without qualifying to make a regular annual Roth IRA contribution.

December 31st

Any Backdoor Roth IRA planning should involve an additional diligence step: ensuring that as of December 31st of the year of the Roth conversion step, the taxpayer has a zero balance in all traditional IRAs, SEP IRAs, and SIMPLE IRAs. This helps ensure the Backdoor Roth IRA is a tax-efficient tactic.

The Pro-Rata Rule

The Backdoor Roth IRA works well for someone with Mike’s profile. But it does not work well for everyone. Let’s change up the example a bit.

Jennifer’s story is the same as Mike’s story above, except that she had a separate traditional IRA before she did her 2024 nondeductible IRA contribution. That separate IRA had no basis. As of December 31, 2024, that separate traditional IRA was worth $92,988.53.

This one change in facts dramatically increases Jennifer’s taxable income from the Roth IRA conversion. Jennifer must apply the so-called Pro-Rata Rule to the Roth IRA conversion. Even though her two IRAs are in separate accounts, they are treated as one IRA for purposes of determining how much of Jennifer’s $7,000 of basis she recovers upon her Roth IRA conversion.

Jennifer starts with $7,011.47 of income (the amount she converts). To determine the amount of her $7,000 of basis she gets to recover against the proceeds of the Roth IRA conversion, we must multiply that $7,000 times the amount converted ($7,011.47) divided by the sum of the amount converted and her traditional IRA balance at the end of the year ($7,011.47 plus $92,988.53). Thus, Jennifer gets to recover 7.00147 percent of the $7,000 of basis, which is only $490.80. This results in Jennifer’s Roth IRA conversion increasing her taxable income by $6,520.67 ($7,011.47 minus $490.80).

What was a great idea for Mike becomes a horrible idea for Jennifer when she has a significant balance in another traditional IRA.

Note further that Jennifer would have the same bad outcome if that $92,988.53 traditional IRA was instead in a traditional SEP IRA or in a traditional SIMPLE IRA.

Tax Reporting

Assume Mike did his Roth IRA conversion and did not have any other money in traditional IRAs in 2024. He will get a Form 1099-R from his financial institution. In box 1 it will report a gross distribution of $7,011.47 (the amount of the Roth IRA conversion).

In box 2a the Form 1099-R will say that the “taxable amount” is $7,011.47 and box 2b will be checked to indicate that the “taxable amount not determined.” Wait, what? How can $7,011.47 be the taxable amount while the next box claims the taxable amount is not determined? The answer is the basis concept discussed above.

Mike’s financial institution does not know the rest of Mike’s story (his income, retirement plan coverage at work, IRAs at other institutions, etc.), so it has no way of determining how much basis, if any, Mike recovers when he did the Roth IRA conversion. Box 2b simply means that Mike might have recovered some basis, but the institution is not in a position to determine if he did.

Form 8606 helps complete the tax reporting picture. By filing that form, Mike establishes that he was entitled to $6,000 of traditional IRA basis and how the pro-rata rule applies (if at all) to his Roth IRA conversion. It is important that Mike file a properly completed Form 8606 with his timely-filed 2024 federal income tax return.

When Mike files his 2024 Form 1040, he puts $7,011.47 on line 4a (“IRA distributions”) and $11.47 on line 4b (“Taxable amount”). Most tax return preparation software will round cents to the nearest whole dollar.

Note that failing to report the transactions on the Forms 8606 and 1040 in this way can result in Mike paying an incorrect amount of tax.

The Basics

Section 199A, enacted in December 2017 as part of tax reform, gives owners of businesses (including partners, owners of S corporations, and sole proprietors) that generate QBI a deduction in the amount of 20 percent of the QBI.

In January 2019, the IRS and Treasury issued regulations providing detailed rules under Section 199A. Those rules define QBI. As part of the definition of QBI, taxpayers must subtract contributions to self-employment retirement plans from QBI.

80% Deductions

When a self-employed individual contributes to a traditional retirement plan, they generally reduce the amount of their QBI deduction (because the retirement plan contribution lowers QBI).

Here’s a quick example (using 2018 tax numbers) of how that works.

Example: Mike makes $50,000 from his sole proprietorship (as reported on Schedule C). He pays $7,065 in self-employment tax (Social Security and Medicare). He deducts half of his self-employment tax ($3,533) from his taxable income and his QBI. Mike is married to Jane. Jane has $34,000 of W-2 wages. Mike and Jane file jointly and take the $24,000 standard deduction.

Mike thus receives a QBI deduction of $9,293 (20% of $46,467). This makes Mike and Jane’s taxable income $47,174 ($50,000 less $3,533 plus $34,000 less $24,000 less $9,293).

Let’s assume that Mike wants to make a $10,000 employee contribution to his Solo 401(k) to lower his taxable income by $10,000. Sure enough, the math does not work that way due to the QBI deduction. Mike’s QBI is now $36,467 (the original QBI of $46,467 less the $10,000 traditional Solo 401(k) contribution). Thus, his QBI deduction is now reduced to $7,293 (20% of $36,467). This makes Mike and Jane’s taxable income $39,174 ($50,000 less $3,533 plus $34,000 less $24,000 less $10,000 less $7,293).

Notice that $39,174 is $8,000 less than $47,174, not $10,000 less than $47,174. The interaction of Section 199A and the small business retirement plan creates the oddity that a $10,000 deduction (the traditional Solo 401(k) contribution) reduces taxable income by only $8,000.

QBI has thus created a new class of deductions – what I call “80% deductions.” These deductions reduce QBI and thus (in total effect) are deductible at only 80 percent of their gross amount.

As applied to small business retirement plans, 80% deductions are particularly troublesome. Recall Mike put $10,000 into his Solo 401(k), netting him an $8,000 federal tax deduction. When Mike goes to take the $10,000 (and its growth) out of the Solo 401(k), all of it will be taxable.

Matching 80% deductions with 100% inclusions is usually not smart tax planning.

I’ve written more about this phenomenon (what I call the Solo 401(k) Trap) here.

Planning Options

In cases where taxpayers are below the taxable income limitations of Section 199A ($163,300 and $326,600 (MFJ) for 2020), taxpayers will have to weigh the benefit of the 80 percent deduction for a traditional contribution to a small business retirement plan versus other options. Some of those other options include (if eligible):

Make employee contributions to a Roth IRA, Roth Solo 401(k), and/or after-tax contributions to a Solo 401(k)
Make contributions to a health savings account (a “HSA”)
Make contributions to a traditional IRA
Invest the earnings in taxable accounts and/or pay off existing debt.

Roth Contributions

Roth versus traditional receives much Internet discussion, particularly in the FI community. All agree that a taxpayer’s current marginal tax rate is vitally important. 80% deductions lower marginal tax rates. Take Mike, who with his retirement plan contributions lowered his 2018 taxable income to $39,174. As a married filing joint taxpayer, his marginal federal income tax rate is 12 percent. However, the marginal rate on the $10,000 retirement plan traditional contribution is only 9.6 percent (80 percent of 12 percent). In order for the traditional contribution to be advisable, Mike better be pretty sure he can pull the money out of the Solo 401(k) at a marginal federal tax rate below 9.6 percent. Being that the lowest marginal tax rate is 10 percent today, that does not seem very likely.

In Mike’s case, he would have been much better advised to leave his taxable income at $47,174 and made the Solo 401(k) contribution a Roth Solo 401(k) contribution.

HSAs/IRAs/Small Business Retirement Plans

Many small business owners are looking for current tax deductions, and many are in marginal tax brackets much above the 12 percent bracket. The interaction between Section 199A and small business retirement plans creates a new pecking order for self-employed individuals looking to reduce taxable income through plan contributions. That order is as follows:

HSA Contributions (if eligible)
Deductible Traditional IRA Contributions (if eligible)
Traditional Small Business Retirement Plan Contributions

HSA Contributions

I’ve written about my fondness for HSAs here. What’s important for this purpose is that contributions to HSAs do not reduce QBI. Thus, contributions to HSAs are “100 percent deductions” and not 80% deductions. In addition to all their other advantageous tax attributes, HSA contributions should be prioritized over small business retirement plan traditional contributions from a Section 199A perspective.

Deductible Traditional IRA Contributions

Deductible contributions to traditional IRAs (for those who qualify) also should be prioritized over traditional contributions to small business plans from a Section 199A perspective.

In the previous version of this post, I expressed the concern that deductible traditional IRA contributions might reduce QBI. Fortunately, there is nothing the IRS and Treasury has provided (including the instructions to the new Form 8995) indicating that the government believes deductible traditional IRA contributions reduce QBI. Based on my understanding of the tax law, which has been reinforced by IRS and Treasury silence on the matter, I am comfortable that deductible traditional IRA contributions should not reduce QBI.

Taxable Accounts

There is no requirement to contribute to small business retirement plans. You can simply take profits and invest them in taxable accounts. Considering that traditional small business retirement plans contributions are now 80% deductions that must later create 100% income, you may opt to simply not make plan contributions and keep profits in taxable accounts. That may be very sensible if either or both the following are true: 1) you are currently in a very low marginal federal tax bracket and 2) you anticipate being in a much higher marginal federal tax bracket in the future.

S Corporation Owners

For S corporation owners, only the operating income after the owner’s W-2 salary is eligible for the Section 199A deduction. Small business retirement plan contributions are 80% deductions for the S corporation owner just as they are for the sole proprietor and for partners of partnerships with flow-through QBI.

Consideration should be given to employee versus employer contributions. To my mind, the new Section 199A deduction does not necessarily impact whether to make an employee contribution to a Solo 401(k) as a W-2 employee of your business. Yes, your salary is an 80% deduction. But what you from there with your salary (take it home, put it into a traditional Solo 401(k), or put it into a Roth Solo 401(k)) does not increase or decrease your qualified business income (though it could impact the taxable income limitations).

But an employer contribution to a Solo 401(k) (which must be a traditional contribution) does reduce your QBI. Employer contributions to Solo 401(k) plans often fall into the Solo 401(k) Trap.

In many cases, if you qualify for the QBI deduction you should give strong consideration to foregoing the employer contribution. Planning in this regard can benefit from professional consultations.

Your Employees

If you have employees, offering a SIMPLE IRA plan does not change the Section 199A result with respect to their salary. Normal operating expenses (including salaries) of QBI-generating businesses do create 80% deductions, but there is only so much that can be done about that. Unlike your own retirement plan contributions, which are (almost) entirely discretionary, operating expenses are necessary for the conduct of the business. Giving your employees the option of deferring some of their salaries through a SIMPLE IRA does not change the math on the Section 199A deduction, since employees’ salaries reduce QBI regardless of whether the employees contribute some of their salary to a SIMPLE IRA.

The relatively small mandatory employer contribution to employees’ SIMPLE IRAs are 80% deductions, making them a bit more expensive for the business owner (assuming the owner qualifies to claim the QBI deduction).

The Section 199A QBI deduction makes SEP IRA contributions more expensive for most self-employed business owners. In order to make contributions to his/her own SEP IRA, the owner must also make contributions (in an equal percentage of compensation) to the employees, and now those deductions are only 80% deductions (assuming the owner qualifies to claim the QBI deduction).

Upper Income Taxpayers

For some taxpayers, Section 199A will make their small business retirement plan contributions more, not less, valuable. In a previous post, I gave the example of Jackie, a sole proprietor lawyer whose 2020 taxable income (pre-retirement plan contributions) of $215,848 left him unable to claim any Section 199A QBI deduction. Maximum employer and employee traditional contributions of $57,000 to a Solo 401(k) lowered his taxable income such that he was able to qualify for a $31,770 QBI deduction (a 100% deduction) in addition to the $57,000 traditional retirement plan contribution deduction (an 80% deduction).

This interaction turned the $57,000 deduction into an effective $77,370 deduction (80 percent of $57,000 plus $31,770). In this case, Jackie’s retirement plan contributions are 136% deductions!

For upper income taxpayers near the QBI taxable income limitations, small business retirement plans may be a very powerful tool, and unlike those with more modest incomes, these upper income business owners may have an opportunity to maximize their Section 199A deduction by contributing to retirement plans.

Conclusion

The combination of Section 199A and small business retirement plans creates tax planning opportunities and challenges. Many small business owners will benefit from professional advice to determine the best path forward considering the new law, opportunities, and challenges.
