2026 Backdoor Roth IRA Timing

Merry Christmas and Happy New Year!

The Christmas season (ending January 11th this year) coincides with the beginning of personal finance’s Backdoor Roth IRA season. 

Many readers look forward to New Year’s Day not to watch the Rose Bowl but rather to contribute to a traditional IRA, the first step of the Backdoor Roth IRA. 

The question then becomes: how long should I wait to do the second step of the Backdoor Roth IRA, the conversion of the traditional IRA contribution and any small growth to a Roth IRA?

Below I discuss my views on the matter as they apply to 2026 Backdoor Roth IRAs. 

Backdoor Roth IRA Timing Concerns

The Backdoor Roth IRA involves three accounts and two steps. First, the investor transfers money from a bank account (A) to a traditional IRA (B) as a regular annual contribution to the traditional IRA. Second, the investor converts the entire traditional IRA balance to a Roth IRA (C).

Written out logically, the Backdoor Roth IRA sequence is as follows:

A→B→C

The question is “do we respect the transfer to B or do we disregard the transfer to B and say, instead, that there was a single transfer from A to C?

Michael Kitces, in 2015, wrote an article stating that he was, at that time, concerned that, if the Roth conversion step was done close in time to the traditional IRA contribution, the transfer to the traditional IRA would be disregarded. For high income individuals, this would create an excess contribution to a Roth IRA subject to a 6% annual penalty.

I do not share his concern. My perception is that most financial planners, financial advisors, and tax return preparers also do not share his concern. 

My Approach

I wrote a detailed blog post stating that I do not believe the step transaction doctrine invalidates the Backdoor Roth IRA. Of particular note is Section 408(d)(2)(B), which provides that all IRA distributions (including Roth conversions) during the year are aggregated into a single distribution. 

This rule tells us that timing within the year is irrelevant for determining tax treatment. Why would a judicial doctrine change the Backdoor Roth IRA’s tax treatment based on a timing concern when the Code itself says timing is irrelevant? 

Favored Backdoor Roth IRA Timing

Here is my favored approach: Make the traditional IRA contribution at any time during a particular month and then wait until the following calendar month to do the Roth conversion step. Usually the traditional IRA is invested in a low yielding stable cash or cash equivalent type of asset, creating a small bit of income in between the two steps. 

Here is how that plays out with an example:

Keith, age 47, wakes up on New Year’s Day 2026 and contributes $7,500 to a traditional IRA invested in a money market fund. On February 2, 2026, when the traditional IRA has grown to $7,525, he converts all of it to a Roth IRA. 

Yes, Keith could have converted the $7,500 to a traditional IRA on January 2, 2026. I would strongly argue that he has a good Backdoor Roth IRA in that scenario.

But my favored approach is for him to wait until February. Why not? What’s the downside to my favored approach? Practically none. My favored approach increases Keith’s taxable income by $25, which is obviously no big deal. It also buys Keith a bit more protection against the step transaction doctrine concern (which, admittedly, I believe to be a minimal concern). 

Backdoor Roth IRA Diligence

Allow me to touch on two important diligence points when doing the Backdoor Roth IRA.

The first is to ensure that as of December 31st of the year of any Roth conversion step (so 2026 in Keith’s example), it is important to have $0 (or close to $0) in all traditional IRAs, SEP IRAs, and SIMPLE IRAs. For more discussion as to why that’s important, see this post. 

Second, it is important to properly complete the Form 8606 and file it with the annual federal income tax return. This post has an example of how a Form 8606 is completed to reflect a Backdoor Roth IRA. 

Further Reading

In early 2026 many Americans will find they made too much to have made their 2025 Roth IRA contribution. Having contributed in 2025, they now need to remedy the overcontribution. Further, they may still want to do a Backdoor Roth IRA for 2025 in 2026, what I refer to as a Split-Year Backdoor Roth IRA.

The Backdoor Roth IRA After an Excess Contribution to a Roth IRA

It happens all the time. People contribute to a Roth IRA only to find out at tax time they made too much income to have made the Roth IRA contribution. 

There are two primary ways to correct this situation. They are a recharacterization and a corrective distribution. Both are entirely valid remedial paths when it turns out that one contributed to a Roth IRA and their income was too high to have done so. 

But which remedial path makes the most sense if the investor wants to also do a Backdoor Roth IRA for the year in question?

As I am posting this in late 2025, this is about to become very relevant as applied to excess Roth IRA contributions occurring in 2025. Many will find out in early 2026 as they work through their 2025 tax return that they did not qualify for a previously made 2025 Roth IRA contribution. 

Below I explore this topic with two examples. 

Recharacterization

Let’s consider Rich and Rebecca, married and both age 48 in 2025. At least one of them was covered by a workplace retirement plan in 2025. Rich and Rebecca each contributed $7,000 to a Roth IRA on January 2, 2025 anticipating their 2025 modified adjusted gross income would be approximately $225,000. Due to a year-end bonus and unexpected capital gains distributions, their 2025 MAGI turned out to be $250,000, which they discovered after talking to their income tax return preparer in February 2026. 

Having exceeded the 2025 Roth IRA MAGI contribution limit of $246,000, they need to remedy the situation. Since neither of them has any balance in a traditional IRA, SEP IRA, and/or SIMPLE IRA, they are also interested in doing a Backdoor Roth IRA for 2025 (what I refer to as a Split-Year Backdoor Roth IRA). 

They proceed as follows. First, they ask their financial institution to recharacterize their 2025 Roth IRA contributions and related earnings ($550 in Rich’s case, $600 in Rebecca’s case) as traditional IRAs in late February 2026. This event does not create any 2025 or 2026 taxable income. 

Second, in early March 2026, Rich converts the balance in his traditional IRA, now $7,560, from his traditional IRA to a Roth IRA. Likewise, Rebecca converts the balance in her traditional IRA, now $7,612 from her traditional IRA to a Roth IRA. This creates $560 of 2026 taxable income for Rich and $612 of 2026 taxable income for Rebecca. 

Both Rich and Rebecca have $0 balances in all traditional IRAs, SEP IRAs, and SIMPLE IRAs as of December 31, 2026. 

I believe that it’s helpful to illustrate the sequence logically using letters. A is a checking account, B is a traditional IRA, and C is a Roth IRA.

Here is how the entire sequence looks when Rich and Rebecca first contribute to a Roth IRA, correct it through a recharacterization, and then do the Split-Year Backdoor Roth IRA. 

A→C→B→C

Corrective Distribution

Let’s consider Carl and Debbie, married and both age 47 in 2025. At least one of them was covered by a workplace retirement plan in 2025. Carl and Debbie each contributed $7,000 to a Roth IRA on January 2, 2025 anticipating their 2025 modified adjusted gross income would be approximately $225,000. Due to a year-end bonus and unexpected capital gains distributions, their 2025 MAGI turned out to be $255,000, which they discovered after talking to their income tax return preparer in February 2026. 

Having exceeded the 2025 Roth IRA MAGI contribution limit of $246,000, they need to remedy the situation. Since neither of them has any balance in a traditional IRA, SEP IRA, and/or SIMPLE IRA, they are also interested in doing a Backdoor Roth IRA for 2025. 

They proceed as follows. First, they ask their financial institution to send them a corrective distribution of their 2025 Roth IRA contributions and related earnings ($650 in Carl’s case, $700 in Debbie’s case) in late February 2026. 

The February 2026 corrective distribution of the excess Roth IRA contributions and related net income attributable to the returned contributions creates taxable income of $650 to Carl and $700 to Debbie in 2025 to be reported on their soon-to-be-filed 2025 federal income tax returns. See Section 408(d)(4)(C), Treas. Reg. Sec. 1.408A-6 Q&A 1(d), and this Vorris J. Blankenship article. 

Second, in late February 2026, both Carl and Debbie make a $7,000 contribution to their traditional IRAs and code the contribution as being for 2025. 

Third, Carl converts the balance in his traditional IRA, now $7,010, from his traditional IRA to a Roth IRA. Likewise, Debbie converts the balance in her traditional IRA, now $7,010, from her traditional IRA to a Roth IRA. This creates $10 of 2026 taxable income for Carl and $10 of 2026 taxable income for Debbie. 

Both Carl and Debbie have $0 balances in all traditional IRAs, SEP IRAs, and SIMPLE IRAs as of December 31, 2026. 

Here is how the entire sequence looks when Carl and Debbie first contribute to a Roth IRA, correct it through a corrective distribution, and then do the Split-Year Backdoor Roth IRA. 

A→C→A→B→C

Critical Assessment

Let’s step back. Logically, what is the Backdoor Roth IRA? It boils down to the following formulation:

A→B→C

I and others have argued that “B” should be respected. I’m unaware that the IRS disagrees with this view. At this point, after a decade and a half of Backdoor Roth IRAs, it would be exceedingly odd for the IRS to start aggressively challenging the transaction. 

Assessing the Corrective Distribution Remedial Path

Viewed logically, the “corrective distribution followed by the Split-Year Backdoor Roth IRA” is just as strong as the Backdoor Roth IRA itself. It simply appends two additional transactions, an (ultimately excess) Roth IRA annual contribution followed by a corrective distribution. If one can defend the Backdoor Roth IRA, one should be able to defend the corrective distribution followed by the Split-Year Backdoor Roth IRA.

You might argue that the money was in a Roth IRA and ultimately ends up back in a Roth IRA. That can be true, though the investor need not use the exact same dollars received in the corrective distribution to initiate the later Split-Year Backdoor Roth IRA. 

Regardless, in order to “collapse” steps, the IRS would need to successfully defeat not one, but two, steps. First the IRS would need to successfully disregard the corrective distribution on which the investor most likely reports taxable income. Second, the IRS would need to disregard the transfer to the traditional IRA. 

The IRS has not aggressively tried to disregard a single step (the traditional IRA contribution) when it comes to the Backdoor Roth IRA transaction for the past 15 years. It’s difficult to imagine the IRS would try to aggressively disregard two distinct steps, which is what it would take to defeat the “corrective distribution followed by the Split-Year Backdoor Roth IRA” path. 

Assessing the Recharacterization Remedial Path

Where I get much more concerned is the “recharacterization followed by the Backdoor Roth IRA” path. 

In all of these analyses, the key issue is “do we respect “B”?” Recall the recharacterization followed by the Backdoor Roth IRA formulation:

A→C→B→C

Notice what’s on both sides of B? 

C!

We have a case where funds are in a Roth IRA, temporarily rest in a traditional IRA, and then end up right back in a Roth IRA. 

Yes, the Internal Revenue Code allows recharacterizations. But could the IRS successfully disregard a recharacterization into a traditional IRA when both immediately before and immediately after those funds are in a Roth IRA?

I believe that a recharacterization followed by a Split-Year Backdoor Roth IRA dramatically increases the risk to the investor. The risk is that the recharacterization would be disregarded, exposing the investor to the annual 6% excess Roth IRA contribution penalty. 

Favored Approach

I strongly favor the corrective distribution remedial path if one is looking to do a Backdoor Roth IRA after having made an excess contribution to the Roth IRA for the year.

What are the drawbacks to my favored approach? It requires three steps instead of two, since the investor must initiate the corrective distribution, contribute to a traditional IRA, and then convert the traditional IRA. 

Further, my favored approach generally accelerates the tax on the “net income attributable” to the excess contribution. Recall Rich and Rebecca pay that tax in 2026 while Carl and Debbie pay practically all of that tax with their 2025 federal income tax returns. 

My favored approach generally does not increase the small tax created by the combination of the remediation and the Split-Year Backdoor Roth IRA. It simply accelerates it by one year. In a low yield world, that is a tiny drawback. 

I believe that the corrective distribution remedial path is very strong. I do not believe that the IRS would stand a very good chance of disregarding two steps to create an excess contribution to a Roth IRA. Further, I believe that respecting time spent in a traditional IRA is much more challenging when that money is in a Roth IRA immediately before and immediately after being in the traditional IRA. 

When both corrective distributions and recharacterizations are available to those looking to ultimately do a Backdoor Roth IRA, why not choose the corrective distribution path? 

Finally, note that this blog post is not advice for you or anyone else. I am not writing that the recharacterization remedial path cannot work. Rather, I am, in an academic sense, simply stating two things.

First, the recharacterization followed by a Split-Year Backdoor Roth IRA path increases the risk to the investor.

Second, the corrective distribution path appears to be preferable to the recharacterization path if one is looking to do the Split-Year Backdoor Roth IRA after an excess contribution to the Roth IRA for the same year. 

The Real Answer

Congratulations on reading a blog post that should not exist! The real answer to this issue isn’t my analysis. Rather, it is for Congress to eliminate the MAGI restriction on the ability to make an annual Roth IRA contribution. This would align American rules with Canadian rules.
