Saving for retirement in tax-preferenced retirement accounts is often one of the primary objectives for the clients of advisors, where most contributions made to a taxpayer’s retirement accounts are either deductible contributions to a traditional retirement account (IRA, 401(k), 403(b), or similar), or nondeductible (after-tax) contributions made to a Roth-style account (Roth IRA, Roth 401(k), Roth 403(b), or other designated Roth account).
Occasionally, however, clients make after-tax contributions to traditional accounts that are usually designated for pre-tax funds. Such contributions have already been taxed, and should not be taxed again. Unfortunately, though, such after-tax contributions are often ‘lost’ when clients forget that these amounts were after-tax, or do not track and report them on their tax returns correctly, potentially leading to double taxation when subsequent distributions are taken and this IRA basis is not accounted for.
Accordingly, advisors can help clients keep track of such after-tax amounts, and to recover any after-tax amounts that have previously gone missing.
Direct creation of IRA basis via nondeductible IRA contributions
The primary way in which basis is created within a traditional IRA is via nondeductible (after-tax, for example) IRA contributions. Such contributions typically occur when a taxpayer is eligible and chooses to make a contribution to their traditional IRA, but is phased out of being able to claim a deduction for that contribution (or voluntarily chooses not to deduct the contribution, which can, in rare cases, be advantageous).
Notably, as a result of the
But while having compensation is the only requirement to make a traditional IRA contribution, it doesn’t guarantee that such a contribution will be deductible, even though it was made to a traditional IRA.
More specifically, if a taxpayer and/or their spouse (if applicable) is an active participant in an employer-sponsored retirement plan (for example, 401(k), 403(b), 457(b), pension, SEP IRA, SIMPLE IRA, TSP, etc.,) and has income that exceeds a specific threshold, then their ability to deduct Traditional IRA contributions is reduced or eliminated altogether. In other words, the contribution itself can still be made as long as there is earned income to contribute… but the deductibility of that contribution phases out.
For 2021, the phaseout ranges for claiming a deduction for a contribution made to the traditional IRA of an active participant are as follows:
Example #1: Albert and Minerva are married taxpayers who have AGI of $150,000 in 2021. Both are employed and are active participants in their respective employers’401(k) plans. Each also makes a $6,000 contribution to their traditional IRA accounts for 2021.
Albert and Minerva have compensation for 2021, so each of their $6,000 contributions are allowable. However, since both are active participants in their respective employer plans, and their $150,000 income exceeds their applicable maximum phaseout amount of $125,000 for married taxpayers, they will not be able to receive a deduction attributable to those contributions.
Accordingly, both Albert and Minerva will have made nondeductible traditional IRA contributions.
On the other hand, deductions for a contribution made to the traditional IRA of an individual who is not an active participant in an employer’s plan themselves, but who is married to an active participant, may also be phased out, but are subject to the following, separate phaseout ranges:
Example #2: James and Lily are married taxpayers who have an AGI of $150,000 in 2021. Both are employed, but only Lily is an active participant in an employer-sponsored retirement plan. Both James and Lily make a $6,000 contribution to their traditional IRA for 2021.
James and Lily have compensation for 2021, so each of their $6,000 contributions are allowed. Furthermore, since James is not an active participant in an employer-sponsored retirement plan (but his spouse, Lily, is), and the couple’s income of $150,000 is below the threshold limit of $198,000, he is able to claim a deduction for the contribution made to his traditional IRA.
However, since Lily is herself an active participant and the couple’s income of $150,000 exceeds the applicable maximum phaseout amount of $125,000, they will not be able to receive a deduction attributable to Lily’s traditional IRA contribution.
Accordingly, for 2021, James will have a deductible traditional IRA contribution (for being under the spousal active participant income limit) and Lily will have a nondeductible traditional IRA contribution (for being over the direct active participant income limit).
The indirect creation of IRA basis via rollovers of after-tax dollars in an employer-sponsored retirement plan
In addition to nondeductible contributions creating basis in a traditional IRA, basis can also make its way into a traditional IRA when after-tax dollars are rolled over to a traditional IRA from an employer-sponsored retirement plan.
There are, however, several reasons why this is less likely to be the way clients may end up with after-tax dollars in their traditional IRA accounts (as compared to making nondeductible contributions, described above).
First, while anyone with compensation can make a contribution to a traditional IRA, only a relatively small group of taxpayers actually has the ability to make after-tax contributions to an employer-sponsored retirement plan.
This is because after-tax contributions to defined contribution plans ‘play’ on the difference between the IRC Section 402(g) salary deferral limit ($19,500 for 2021), which limits the amount an employee can elect to defer from their salary, and the 415(c) overall/annual additions limit ($58,000 for 2021), which consists of both elective deferrals (including 402(g) salary deferrals) and employer contributions.
But both limits are not applicable to all plans. SEP IRAs, for instance, don’t allow employees to contribute any of their own funds to the plan and thus the 402(g) salary deferral limit does not apply. Instead, all contributions to SEP IRAs are made by the employer, deductible to the employer, and taxable to the employee. SIMPLE IRAs are subject to separate limits on contributions and are not permitted to offer Roth options that would allow after-tax contributions. And for governmental 457(b) plans, only the 402(g) salary deferral limit applies so after-tax contributions are never made to these plans.
So, in the end, it’s primarily just traditional 401(k) and 403(b) plans that have the 402(g) salary deferral limit, and that are eligible for the higher 415(c) overall annual additions limit that makes it feasible to add after-tax contributions on top.
Example #3: Harry is a participant in the ABC, Inc. 401(k) plan, which allows after-tax contributions. In 2021, Harry maximizes his salary deferral contribution of $19,500. His employer contributes an additional $8,500 to the plan on his behalf, bringing total additions to the plan for 2021 to $28,000.
With the overall limit of annual additions for 2021 plan contributions set at $58,000 by IRC 415(c), Harry has $58,000 (overall limit) – $28,000 (total 2021 contributions made to date) = $30,000 of ‘free space’ in his ABC 401(k) for 2021.
Accordingly, Harry could make up to $30,000 of additional after-tax contributions to his 401(k) for 2021, assuming the contributions pass the requisite tests for highly compensated employees, such as the Actual Contribution Percentage (ACP) test.
Second, just because an employer-sponsored retirement plan can offer participants the opportunity to make after-tax contributions, it doesn’t mean they have to do so. In fact, to the contrary, the decision to allow plan participants to make such contributions is 100% at the plan’s discretion.
To that end, while 403(b) plans can allow for such contributions, finding such plans that choose to do so is exceedingly rare. And while the option is adopted more frequently in 401(k) plans, it is still far from what you might call “widespread” (though it has become somewhat more common in recent years as a way to accommodate those who want to do
Third, even when a plan does offer participants the ability to make after-tax contributions, not all participants will choose to do so. And even when they do choose to make after-tax contributions, it’s not uncommon to find high-income plan participants who are prevented from doing so because of non-discrimination testing (as even a safe-harbor plan does not exempt after-tax contributions from the
Finally, as a result of (somewhat) recent guidance, no new rollovers of after-tax dollars should be made from an employer-sponsored retirement plan to a traditional IRA … because there is now a better option for those after-tax rollover dollars. In fact, the last time such rollovers should have occurred was back in 2014,
In short, the notice clarified that if a distribution from an employer-sponsored retirement plan contained both pre- and post-tax dollars, the post-tax dollars could be split from the pre-tax dollars and sent, separately from the pre-tax dollars, to a Roth IRA as a tax-free conversion.
Given that such a conversion would ‘transform’ all future earnings from being taxable (if earned and distributed from a traditional IRA after a rollover) to tax-free (if earned inside a Roth IRA and distributed as a Qualified Distribution) at a cost of $0 (since the dollars are after-tax in the first place and thus not taxable when Roth converted), since the release of
Accordingly, over time, fewer and fewer traditional IRA owners should find themselves with after-tax dollars in their accounts as a result of a rollover from an employer-sponsored retirement account.
Nevertheless, prior to the release of

How traditional IRA basis is lost: The case of the disappearing basis
One common question asked by taxpayers who have after-tax dollars in a traditional IRA account is, “Who keeps track of this stuff?” Oftentimes, taxpayers think that their IRA custodian is keeping track of these amounts for them.
Newsflash, they’re not.
Rather, while after-tax funds in an employer-sponsored retirement plan (for example, a 401(k) or 403(b)) are tracked by the plan’s administrator (or at least, they should be), taxpayers are on their own when it comes to keeping track of the after-tax amounts in a traditional IRA, including after-tax amounts rolled into a traditional IRA from an employer-sponsored retirement plan. Specifically, taxpayers are required to file
With such a precisely defined way of keeping track of after-tax dollars in a taxpayer’s traditional IRA — a dedicated IRS Form 8606 for just that purpose — one might think that it would be hard to lose track of such amounts. Unfortunately, though, for a variety of reasons, that’s not the case. Instead, lost basis (after-tax funds) is a common problem, which often goes undetected, and can lead to double taxation of the after-tax funds.
Form 8606 might have never been filed
One common way taxpayers lose track of after-tax funds is that they simply fail to file Form 8606 from the get-go. In such instances, the IRS may never be made aware of the after-tax dollars in a client’s traditional IRA.
Oftentimes, the failure to file Form 8606 is due to a Cool Hand Luke problem — “What we’ve got here, is failure to communicate.”
Simply put, a client makes a nondeductible contribution to a traditional IRA, and they never tell their CPA or other tax professional, either because they assume their tax professional already knows (but really, how would they) or they simply forget to tell them. Accordingly, Form 8606 is never filed.
In other cases, the taxpayer may file their own return and may not know to file Form 8606. And, of course, tax preparers are not infallible. Mistakes occasionally happen, and one of those mistakes could be a preparer’s failure to file Form 8606, even if they had all the information necessary to do so.
Filing requirements for Form 8606 make it susceptible to getting lost
Although it’s not terribly uncommon to find a taxpayer who has never filed Form 8606 to begin with, traditional IRA basis is ‘lost’ more frequently due to Form 8606’s own (lousy) filing requirements and the passage of time.
Because simply put, the Instructions for Form 8606 only require that it be filed for purposes of reporting after-tax amounts when one of the following events occurs:
- After-tax money goes into the traditional IRA (via a nondeductible contribution or a rollover of after-tax funds from an employer-sponsored retirement plan); or
- After-tax money comes out of the traditional IRA via a distribution (including a Roth conversion).
As a result of the limited filing requirements, which only trigger when money goes in or comes out of a traditional IRA with after-tax dollars, there can be many years, and in some cases, even decades, between events that require the filing of Form 8606.
Example #4: Myrtle is a single taxpayer who just turned 50 years old, and who has her sights set on retiring at 60. Accordingly, Myrtle wants to put away as much money as possible for retirement on a tax-preferenced basis each year until she retires.
Myrtle is a participant in her employer’s 401(k) plan, and after maxing out her contributions to the plan, her 2021 AGI is $150,000. She also makes the maximum contribution of $7,000 to her traditional IRA for 2021.
However, since Myrtle is an active participant in an employer-sponsored retirement plan and her AGI is above the applicable phaseout threshold of $76,000 for single filers, the entire contribution to her traditional IRA is nondeductible.
When Myrtle goes to file her 2021 tax return, she makes sure to inform her tax preparer that she made a nondeductible contribution to her traditional IRA, thus avoiding the Cool Hand Luke problem.
Accordingly, her tax preparer properly files form 8606, reporting $7,000 of after-tax amounts in her traditional IRA as of the end of 2021.
Assume that the same sequence of events occurs in each of the next nine years. In each year, Myrtle makes a $7,000 nondeductible contribution to her traditional IRA, and each year, her tax preparer records the contribution properly on Form 8606. Accordingly, by the time Myrtle turned 60, Form 8606 shows cumulative after-tax amounts in her traditional IRA of $7,000 × 10 years = 70,000.
Suppose, now, that Myrtle has done such a great job saving for retirement that she’s able to avoid tapping into her traditional IRA for the first 12 years of her retirement. In fact, she only begins to use her IRA funds at age 72 to take her RMDs.
In this case, barring other actions requiring the filing of Form 8606 unrelated to after-tax dollars in a traditional IRA (such as a Roth IRA conversion), Myrtle will go 12 years without ever needing to file the form.
Perhaps unsurprisingly, a lot can happen in 12 years (or 10 years, or five years, or even just a few years) that can result in after-tax dollars being lost to the sands of time. Some common situations that may result in ‘lost’ after-tax dollars include:
- The taxpayer or their tax preparer changes software. Most tax software programs today keep track of the after-tax dollars an individual has in their traditional IRA from one year to the next by carrying forward amounts from previous years indefinitely until there is a change via additional after-tax contributions to the account or distributions that reduce the after-tax amounts in the account.
But while familiarity with tax software (and inertia) makes sticking with the same tax preparation software from year to year the preferred choice for most (whether they be professionals or individuals preparing their own returns), occasionally, the choice is made to change software providers.
In some cases, new software might mean starting fresh and entering everything from scratch. In other cases, particularly with professional preparers, data may be pulled from an old system and imported into a new system. However, such migrations don’t always pull all the data, particularly data that did not show up on a previous year’s return. Thus, when there is no need to update Form 8606 for several years, just pulling data from just the prior year’s return (or tax return software) can miss important traditional IRA tax-basis information.
- The taxpayer changed their professional tax preparer. Another common way for basis to be ‘lost’ is when a taxpayer switches tax preparers after a year in which Form 8606 did not need to be filed. Notably, when individuals change tax preparers, the new preparer generally uses the previous year’s tax return (or sometimes the previous two, or even three years) as a guide for the current year.
In most situations, this allows the new tax preparer to pick up on any relevant items from prior years that could be relevant to the current year’s return, such as net operating loss carryforwards, capital loss carryforwards, AMT credit carryforwards, etc.
Unfortunately, though, while such amounts are reported on a taxpayer’s return annually, if a taxpayer with existing after-tax funds in their traditional IRA did not add to, or reduce, those amounts in the previous tax year (or, perhaps, for many years), Form 8606 will generally not be included with the return, leaving the new preparer unaware of such amounts.
The focus is supposed to be on the wealthy and corporations, since they're the ones who account for the majority of tax misconduct, but what does that mean exactly?
Accordingly, unless the taxpayer, themselves, makes their new tax preparer aware of their existing after-tax amounts — which, sadly, does not occur in many situations – the after-tax amount may be ‘lost’.
The taxpayer dies. A final common way that basis gets ‘lost’ is when a taxpayer with basis in their existing traditional IRA dies. In fact, this scenario may often represent the greatest threat to the loss of after-tax dollars for retirees.
At the time of the taxpayer’s death, it may be many years since the last time Form 8606 was filed and, provided they did not add to or distribute after-tax funds in their traditional IRA in the year of death, Form 8606 may not be required to be filed for that year either.
Ask yourself this, then … how in the world will the decedent’s beneficiaries know about the basis and their inherited IRAs? In many instances, those beneficiaries will be using a different preparer than the decedent’s, so the preparer will have no idea the after-tax funds exist. Beneficiaries are also more likely to move the funds to a new financial advisor, further reducing the list of people who may have any sense or recollection of the basis that exists in their inherited account.
Ultimately, the key point is simply that, because Form 8606 does not need to be filed annually, the ‘traditional’ tax preparation process of checking the past one or several years of tax returns still may fail to capture the reporting of prior years’ after-tax contributions. Which means even if the accountant (or diligent financial advisor) asks for the past several years of tax returns to review, it’s still possible to miss after-tax dollars in a retirement account unless the question is specifically asked, for example, “Have you ever made after-tax contributions to your retirement accounts in years past?”
Filing Form 8606 each year minimizes the chances of losing traditional IRS basis
As is likely evident from the scenarios outlined above, sadly, it’s not all that difficult — or all that uncommon — for taxpayers to lose track of their traditional IRA basis. Thankfully, there’s at least one way to dramatically reduce the likelihood of such an event.
Simply stated, whenever there is basis present in a client’s traditional IRA, they should make sure that they file Form 8606 every year.
Admittedly, in general, taxpayers are better off giving the IRS only what is required, and not voluntarily filing additional forms. Form 8606, however, is an exception to that rule.
By filing Form 8606 each year (even when it is not required), a taxpayer can be sure that as long as each year’s return is reviewed and compared against the last year’s return prior to filing (which, again, is standard practice for professional preparers), the after-tax amounts in their IRA will always be front and center. In other words, the previous year’s return will always indicate the total amount of after-tax amounts in the client’s traditional IRA.
Re-creating lost IRA basis that wasn’t tracked
In the event that IRA basis (the cumulative amount of prior years’ after-tax contributions) has been lost (due to a failure to consistently, or even, file Form 8606), it becomes incumbent on financial advisors to help clients reconstruct such amounts to avoid double taxation.
There are a variety of ways to go about reconstructing prior years after-tax IRA contributions and the associated IRA basis, depending upon how basis was lost and/or what sort of records the client has maintained.
Find the last Form 8606 that was filed
To the extent that a taxpayer previously filed Form 8606 to report after-tax amounts in their traditional IRA, the easiest way to identify the current total of after-tax amounts in their traditional IRA account is to see the total reported on the last Form 8606.
Today, it’s increasingly common for tax returns to be stored digitally. Accordingly, 20 years from now, if this problem arose, it may not be all that unlikely that a taxpayer or their tax preparer would have access to copies of all returns filed for the past several years. The same is true today, though, and it’s not terribly uncommon for taxpayers to have a few years of returns available for review.
In situations where a client with basis in their traditional IRA cannot find a tax return with Form 8606 attached, one option would be
To the extent that a client cannot find a copy of the last Form 8606 filed, or in the event that Form 8606 was never filed, or if the IRS’ copy of the Return Transcript doesn’t contain the Form 8606 details, basis must be ‘reconstructed’ in other ways.
Reconstructing traditional IRS basis from scratch
To reconstruct traditional IRA basis from ‘scratch’, clients need to prove that nondeductible contributions and/or rollovers of after-tax funds from employer-sponsored retirement plans went into their traditional IRA, and that such amounts are still in the account.
So, to begin reconstructing basis, one has to ask themselves, “How can I prove to the IRS what I have contributed to my IRA over the years if it wasn’t reported on a tax return?” Thankfully, there are a number of potential options.
Find prior custodial statements with contributions
One simple option is to simply find custodial statements showing applicable contributions. To the extent a deposited amount is a current- (or prior-) year IRA contribution, it will usually be listed as such in the transaction summary. Today, many custodians often have multiple years of statements available to their customers online, making this process easier than ever before. Not all custodians, however, are as accommodating.
Reference prior Form 5498 filings
To the extent that such statements are unavailable or difficult to obtain, another option for taxpayers who need to quantify and/or prove prior-year traditional IRA contributions is to reference any
Unfortunately, Form 5498 is not needed by taxpayers to file their income tax returns. In fact, it’s not even sent to clients until after the April 15 filing deadline.
Unfortunately, the odd timing of Form 5498, coupled with the fact that it is not necessary to file a tax return, means that only the most diligent record-keeping taxpayers still have them, and more often the form is simply discarded or lost.
In such situations, there’s still one more trick up the knowledgeable advisor’s sleeve.
Request wage and income transcripts from the IRS
While many advisors are familiar with the ability to request a Return Transcript from the IRS, fewer advisors are familiar with the
Quantifying prior basis contributions from (reconstructed) historical records
Once proof of contributions to a traditional IRA that were made has been obtained, the next step in reconstructing basis is to prove that the contributions (as determined using one of the methods outlined above) were indeed non-deductible.
This one’s actually pretty easy. Just look back at prior years’ tax returns and see if there was anything reported on the IRA deduction line. To the extent a taxpayer can find a copy of a return for one or more applicable years, they can again
If a taxpayer can show that both 1) a contribution went into their IRA for an applicable year, and 2) no deduction was taken for the contribution in that year, voilà. It must be a nondeductible contribution and thus … basis found.
Quantifying and proving prior years’ rollovers of after-tax amounts from employer-sponsored retirement plans
As noted earlier, basis of a taxpayer’s traditional IRA account can also result from a rollover of after-tax amounts from employer-sponsored retirement plans. The good news here is that the after-tax amounts inside the taxpayer’s plan should have been tracked by the plan administrator. And when the taxpayer took the distribution from the plan (that was rolled over to the traditional IRA), their
Accordingly, reconstructing such basis is often as easy as digging through some old tax forms to find the Form 1099-R for the year the after-tax amounts were rolled over. Of course, such forms may not have been saved by taxpayers or may have been lost or destroyed.
In such situations, the
To prove that such amounts were rolled over to an IRA account, a taxpayer can take steps similar to those described above for proving nondeductible contributions. Specifically, IRA account statements showing the deposit amounts can be used to verify the rollover, as well as copies of Form 5498, as the form separately reports rollover contributions.
Voilà. Basis found, again.
Most money in traditional IRAs tends to be pre-tax money. Occasionally, however, after-tax amounts find their way into traditional IRAs via nondeductible contributions or rollovers of after-tax funds previously held in an employer-sponsored retirement plan. Such amounts represent already-taxed money, which should not be taxed again (when distributed in the future).
But what should happen and what actually happens are not always the same and, unfortunately, from time to time, taxpayers end up paying tax on the same moneytwice. Sometimes, this double taxation stems from failing to report the after-tax amounts held in a traditional IRA correctly from the start. In other situations, such amounts may have never been reported to the IRS at all.
Thankfully, in both situations, advisors can help clients rectify the problem and keep their income from being taxed only once (which, for most clients, is already more than enough).
To the extent that Form 8606 has been filed correctly in the past and after-tax amounts still exist in a client’s traditional IRA, advisors can suggest that Form 8606 be filed every year, even when it otherwise is not required. And in situations where basis was never reported properly, advisors can work with clients to pull the relevant documents, such as old statements, tax returns, and various IRS transcripts, so that the basis amounts can be reconstructed and reported on the next Form 8606.
At the end of the day, the key point is that the hope for a (partially) tax-free distribution doesn’t have to be lost, even if a taxpayer’s traditional IRA basis (currently) is.
