Case of the Week: 'De-villainizing' Backdoor Roth IRAs

Case of the Week

The ERISA consultants at the Retirement Learning Center Resource regularly receive calls from financial advisors on a broad array of technical topics related to IRAs, qualified retirement plans and other types of retirement savings plans. We bring Case of the Week to you to highlight the most relevant topics affecting your business.

A recent call with a financial advisor from California is representative of a common inquiry related to Roth IRA conversions. The advisor asked:

“Backdoor Roth IRAs sound bad. Are they?”  

Highlights of the Discussion

You won’t find the phrase backdoor "Roth IRA" in the Internal Revenue Code or Treasury regulations. Nor is it a specific product, but the industry has known about the phenomena for years. A backdoor Roth IRA is merely a series of transactions or steps an individual can take to have a Roth IRA – regardless of income level.

The ability to make a 2019 Roth IRA contribution is phased out and eliminated for single tax filers with income between $122,000-$137,000 and for joint tax filers with income between $193,000-$203,000. Consequently, if a person earns too much, he or she cannot make a Roth IRA contribution directly (i.e., through the front door). But, many can still take another route – through a traditional IRA.

For traditional IRA contributions, there are modified adjusted gross income (MAGI) thresholds that apply above which individuals are prevented from making deductible contributions.[1] However, anyone under the age of 70½ with earned income can make a nondeductible contribution to a traditional IRA, regardless of income level. Anyone with a traditional IRA can convert it to a Roth IRA regardless of income level. The traditional-IRA-to-Roth-IRA conversion is another route to having a Roth IRA – what has become known as the backdoor Roth.  

IRA technicians through the years have raised the specter of the “Step Transaction Doctrine” to cast a shadow over the efficacy of the backdoor Roth IRA. The Step Transaction Doctrine is a broad application tax law policy in which the IRS may view a series of separate but related transactions as a single transaction and apply any tax liability based on that transaction rather than the individual transactions in the series. 

A traditional-IRA-to-Roth-IRA conversion is a taxable event to the extent a person converts pre-tax dollars. There are ways to maximize the tax efficiency of the transaction, which is beyond the scope of this post, but the consultants at RLC’s Resource Desk would be happy to have those discussions.

Informal guidance from the IRS and Congress from a year ago seems to have put to rest the concerns about backdoor Roth IRAs and the Step Transaction Doctrine. First, Congress made reference to the legitimacy of the traditional-IRA-to-Roth-IRA conversion in its conference report for the Tax Cut and Jobs Act (see page 289):

“Although an individual with AGI exceeding certain limits is not permitted to make a contribution directly to a Roth IRA, the individual can make a contribution to a traditional IRA and convert the traditional IRA to a Roth IRA.”

Second, in a July 10, 2018, Tax Talk Today, Donald Kieffer Jr., a tax law specialist in employee plans rulings and agreements with the IRS Tax-Exempt and Government Entities Division, said the backdoor Roth is allowed under the law. Kieffer stated:

“I think the IRS’s only caution would be whenever we see words like ‘backdoor’ or ‘workaround’ or other step transactions that are putatively enabling a way to get around limits - especially statutory contribution limits – you generally find the IRS is not happy and prepared to challenge those. But in this one that we’re talking about, it’s allowed under the law.” (emphasis added)


According to IRS and congressional guidance, “backdoor” is no longer a cue for a potentially illicit tax activity when linked to Roth IRA. Therefore, it’s time to “de-villainize” the transaction.
