Which Retirement Account Moves Can't Be Reversed After You Make Them?
Some retirement account transactions can't be reversed once they're made. There's no do-over, and no form you can file later to make everything okay. In some cases, a single transaction can turn a large retirement account into taxable income.
These aren't the same as a bad investment or a missed deadline, which usually have a fix. In this video, we walk through seven mistakes that work differently, from prohibited transactions to Roth conversions, and what to understand before you move the money. With retirement accounts, the most important planning often happens before you click submit, sign the paperwork, or move a single dollar.
Not every retirement account mistake is permanent. For the ones that can be corrected, you may find our video on the top 10 RMD mistakes helpful for understanding what's fixable and what isn't.
Mistake 1: A Prohibited Transaction Inside Your IRA
The IRS doesn't allow certain transactions inside an IRA. They're called prohibited transactions. For example, you generally can't borrow money from your IRA, use it as collateral for a loan, or use IRA money to buy property for your own personal use. This matters most with self-directed IRAs, where you have more control over what the account owns.
The consequence is what surprises people. If you engage in a prohibited transaction, the IRS can treat the account as if it stopped being an IRA as of the first day of that year. That can mean the entire account is treated as distributed to you at fair market value and taxed.
To illustrate, imagine having $800,000 in an IRA and finding out that one prohibited transaction caused the entire account to be treated as distributed. Exactly how that's taxed depends on your situation, but that's the scale of mistake we're talking about.
Illustrative example only. Actual tax results depend on individual circumstances. Consult your tax advisor.
If you're considering anything unusual inside an IRA, understand the rules before you do it.
Mistake 2: A Surviving Spouse Rolling Over an Inherited IRA Too Soon
Spouses have more options when they inherit an IRA. A surviving spouse can usually move that money into their own IRA, but that doesn't mean they should do it right away.
To illustrate, say you're 56 when your spouse passes and you may need some of that money. Keeping it as an inherited IRA can let you take withdrawals without the usual 10% additional tax for taking money out before age 59 and a half. Roll it into your own IRA, and the early-withdrawal rules for your IRA generally apply again. You can usually still roll it into your own IRA later, so there's often no reason to rush.
Illustrative example only. The right choice depends on age, income needs, and other factors. Consult your tax advisor.

Mistake 3: Doing Two 60-Day IRA Rollovers Within 12 Months
This one sounds technical, but it's actually pretty simple. You're generally allowed one IRA-to-IRA 60-day rollover in any 12-month period. Not one per IRA. One.
If you try a second one inside that window, it may not count as a rollover. The pre-tax money can become taxable, and putting it into the receiving IRA can create an excess contribution.
The easier way to avoid this is a direct trustee-to-trustee transfer, where the money moves straight from one custodian to the other. Those transfers aren't subject to the one-per-year limit.
Mistake 4: Rolling Back the Wrong Property
This is another 60-day rollover rule, and it's even easier to overlook. With a 60-day rollover from an IRA, you have to put back the exact same property you took out, not the same dollar value.
To illustrate, say someone takes $150,000 of stock out of their IRA, planning to roll it over. The stock drops, they sell it, and they deposit the cash instead. That breaks the same-property rule. The full $150,000 can become taxable, plus a 10% penalty if they're under age 59 and a half. The cash they put back may also count as an excess contribution.
The frustrating part is that if they'd just put the same shares back, even at the lower price, there'd have been no tax problem at all. It's another reason direct transfers are usually much cleaner when they're available.
Illustrative example only. Actual tax results depend on individual circumstances. Consult your tax advisor.
Mistake 5: Converting Too Much to a Roth
Roth conversions have become one of the most popular retirement tax strategies, which is why this one matters. Years ago, you could undo, or recharacterize, a Roth conversion. Not anymore. Since 2018, a Roth conversion generally can't be reversed back into a traditional IRA.
To illustrate, imagine converting $100,000 and then finding out the tax bill is much bigger than you expected. Or a month later the market drops 20%. Your account may now be worth $80,000, but the conversion was taxed on the full $100,000 it was worth when you converted. You can't say, "Never mind, put it back."
Illustrative example only. Actual tax results depend on individual circumstances. Consult your tax advisor.

Mistake 6: Rolling Company Stock Out of Your 401(k) Without Checking NUA
If you have highly appreciated company stock inside your 401(k), don't automatically roll it into an IRA when you retire. There's a special tax rule that may allow some of that stock's growth to get more favorable tax treatment. It's called net unrealized appreciation, or NUA.
It isn't right for everyone, and it has specific requirements. But once you roll those shares into an IRA, you generally lose that opportunity. So this is something to check before the rollover, not after, ideally with a tax professional who can evaluate your situation.
Mistake 7: Breaking a 72(t) Payment Schedule
A 72(t) plan, formally called substantially equal periodic payments, can let someone under age 59 and a half access retirement money without the usual 10% additional tax. But once the payment schedule starts, it generally has to continue until the later of five years or age 59 and a half.
Change the payments the wrong way before then, and the penalty reaches backward. You could owe the 10% additional tax, plus interest, on the earlier payments that had been penalty-free. This isn't something to adjust casually because you want an extra withdrawal one year.
What All Seven Retirement Account Mistakes Have in Common
The problem isn't picking a bad investment. It's making a transaction before you understand what it changes. A rollover. A distribution. A Roth conversion. Moving company stock. Sometimes clicking submit changes your options permanently.
So before a major move with retirement money, don't just ask, "Can I do this?" Ask, "What options disappear after I do it?"
Frequently Asked Questions About Retirement Account Mistakes You Can't Undo
What is a prohibited transaction in an IRA and what happens if you make one?
A prohibited transaction is a transaction the IRS doesn't allow inside an IRA. Examples generally include borrowing money from your IRA, using it as collateral for a loan, or using IRA money to buy property for your own personal use. These rules matter most with self-directed IRAs, where the account owner has more control over what the account holds. If an IRA owner engages in a prohibited transaction, the IRS can treat the account as if it stopped being an IRA as of the first day of that year. That can mean the entire account is treated as distributed at fair market value and taxed. Exactly how it's taxed depends on the individual situation, which is why understanding the rules before making any unusual move inside an IRA matters.
Should a surviving spouse roll over an inherited IRA right away?
Not necessarily. A surviving spouse can usually move an inherited IRA into their own IRA, but doing it right away isn't always the best choice. A surviving spouse under age 59 and a half who may need some of the money could take withdrawals from an inherited IRA without the usual 10% additional tax for early withdrawals. Once the money is rolled into the spouse's own IRA, the early-withdrawal rules for that IRA generally apply again. Because a surviving spouse can usually still roll the money into their own IRA later, there's often no reason to rush. The right timing depends on age, income needs, and the rest of the plan, so it's worth reviewing with a financial advisor and tax professional.
How many 60-day IRA rollovers can you do in a year?
You're generally allowed one IRA-to-IRA 60-day rollover in any 12-month period. That limit isn't per IRA. It's one rollover total. If you try a second 60-day rollover inside that window, it may not count as a rollover. The pre-tax money can become taxable, and depositing it into the receiving IRA can create an excess contribution. A direct trustee-to-trustee transfer isn't subject to the one-per-year limit, which is one reason direct transfers are often the cleaner option.
What is the same-property rule for IRA rollovers?
With a 60-day rollover from an IRA, you generally have to put back the same property you took out, not the same dollar value. If you take stock out of an IRA, plan to roll it over, then sell the stock and deposit cash instead, that can break the rule and cause the distribution to become taxable. In an illustrative example, if someone takes $150,000 of stock out, sells it after the price drops, and deposits the cash, the full $150,000 can become taxable, plus a 10% penalty if they're under age 59 and a half. Putting the same shares back, even at the lower price, would avoid that problem. This example is hypothetical and individual results will vary.
What is the difference between a 60-day rollover and a direct transfer?
In a 60-day rollover, the money is paid to you and you have 60 days to deposit it into another IRA. In a direct trustee-to-trustee transfer, the money moves straight from one custodian to the other and never passes through your hands. Direct transfers aren't subject to the one-rollover-per-12-months limit, and they avoid the same-property issue that can come with 60-day rollovers. That's why direct transfers are usually much cleaner when they're available.
Can you undo a Roth conversion?
Not anymore. Years ago, a Roth conversion could be undone through a process called recharacterization. Since 2018, a Roth conversion generally can't be reversed back into a traditional IRA. That means the tax bill is based on the value at the time of the conversion, even if the account value drops afterward. In an illustrative example, if someone converts $100,000 and the account later falls to $80,000, the conversion was still taxed on the full $100,000. Because the decision can't be reversed, the tax math is best done before the conversion, including how much to convert, not just how much is possible.
What is net unrealized appreciation (NUA) and why check it before rolling over company stock?
Net unrealized appreciation, or NUA, is a special tax rule that may allow some of the growth in highly appreciated company stock held inside a 401(k) to receive more favorable tax treatment. The strategy has specific requirements and isn't right for everyone. But once company shares are rolled into an IRA, the opportunity is generally lost. That's why it's worth checking NUA before the rollover, ideally with a tax professional who can evaluate whether the strategy makes sense for your situation.
What happens if you change a 72(t) payment schedule?
A 72(t) plan, also called substantially equal periodic payments, can let someone under age 59 and a half take money from a retirement account without the usual 10% additional tax. Once the schedule starts, it generally has to continue until the later of five years or age 59 and a half. If the payments are changed the wrong way before then, the penalty can reach backward. The person could owe the 10% additional tax, plus interest, on the earlier payments that had been penalty-free. Limited exceptions exist, so it's best to review the situation with a tax professional before making any change.
