For inherited IRAs, the 60-day rollover is a one-way door
Slott's first uncorrectable retirement error turns a $400,000 inheritance into an immediate tax bill.
The 60-day rollover reads like one of the friendlier moves in retirement planning. For a non-spouse beneficiary of an inherited IRA, it is a one-way door.
Ed Slott's IRA Advisor, excerpted by Financial Advisor Magazine, puts the move first among seven retirement errors with no corrective step. The newsletter draws a line: most IRA mistakes can be unwound, but these seven bring substantial tax bills, unintended penalties, and lost retirement savings. An excess contribution can be withdrawn without penalty if removed on or before October 15 of the year after it was made. A missed required minimum distribution can be taken and reported to the IRS with a request to waive the penalty. None of those backstops exist for the seven. The deed is the consequence.
The first error, and the one the excerpt details, is a non-spouse beneficiary using a 60-day rollover. Only a spouse can move inherited retirement dollars that way. Every other beneficiary moves money between custodians directly, custodian to custodian. If pre-tax money in an inherited IRA or plan is distributed to a non-spouse beneficiary, it is taxable. No institution will take it back as a rollover, and no transaction exists that reverses the distribution.
Mike's $400,000 mistake
Slott's illustration is a 45-year-old named Mike who inherits a $400,000 IRA from a father who died at 70. Mike is a non-eligible designated beneficiary, so the 10-year payout rule applies. His plan is to withdraw roughly $40,000 a year and stretch the tax bill across the decade. First, though, he wants to move the inherited account to another custodian. He takes a full distribution of the $400,000, made payable to himself, and intends a 60-day rollover. The distribution cannot be put back. The 10-year schedule is gone, and the full amount is taxable immediately.
The rule is easy to miss because it contradicts how rollovers usually work for the account owner's own money. An advisor reviewing an inherited account has one pre-transfer test: is the beneficiary a spouse? If not, a direct custodian-to-custodian transfer is the only route. The paperwork should show the two institutions as the parties, not the individual beneficiary. A check payable to the individual is a distribution, not a rollover.
For an advisor, the moment a client says they intend to move an inherited IRA, the response should be to confirm who the beneficiary is before any custodian form is signed. If the beneficiary is a spouse, the 60-day route is available; anyone else must use a direct transfer. That instruction belongs in writing, and the client should see it before the form is submitted.
The restriction applies to inherited plan dollars as well as inherited IRA dollars. A non-spouse who takes a plan death benefit in cash gets the same result: the money is taxable, and no rollover will be accepted. The instrument does not change the rule; the beneficiary relationship does.
The excerpt, drawn from the June 2026 issue of Ed Slott's IRA Advisor and published by Financial Advisor Magazine on August 19, details the first of the seven errors in full. No waiver, no correction, no do-over. The usual backstops that apply to excess contributions and missed RMDs do not exist once the distribution is made payable to a non-spouse beneficiary. That makes this a pre-signature error, not a post-signature fix.
Slott's example leaves the size of the bill unstated. The exact number would depend on Mike's other income, his state of residence, and the year of distribution. None of that changes the structure: the full $400,000 is taxable in the year it came out, not spread across the ten years the payout rule allows. The custodian check is the irreversible step; the only control is to confirm the beneficiary relationship before the transfer is initiated.
