Rolling over a 401(k) should be a non-event. Done the standard way, no tax is due and your savings land in the new account whole. Yet every year, people get surprise tax bills from rollovers that went sideways.
The rules aren’t complicated. They’re just unforgiving when the money takes the wrong path. Here’s how to keep yours on the right one.
Two Ways Money Can Leave a 401(k)
A direct rollover sends the money straight from your old plan to the new account. Nothing is withheld, nothing is taxed, and there’s no deadline to race. It’s the boring option, and boring is good here.
An indirect rollover means the plan pays you. You then have to deposit the money into a new retirement account yourself. This path has two traps built in.
One detail trips people up. Sometimes the plan mails a check to your home, but it’s made out to the new account provider for your benefit. That still counts as a direct rollover. What matters is whose name is on the payee line, not where the envelope went.
The 20% Withholding Problem
When a 401(k) plan pays money to you, it has to hold back 20% for federal taxes. That’s true even if you plan to roll every dollar over.
Say your balance is $30,000. The plan sends you $24,000 and sends $6,000 to the IRS. To finish a full rollover, you must deposit the whole $30,000 into the new account. That means finding $6,000 from your own pocket. The withheld amount counts as tax paid when you file your return.
Deposit only the $24,000, and the missing $6,000 counts as a withdrawal. It’s taxed as income. If you’re under 59 and a half, a 10% penalty may apply on top.
The 60-Day Deadline
An indirect rollover has to be finished within 60 days of the day you receive the money. Miss it, and the amount is generally treated as taxable income, plus any early withdrawal penalty.
State income tax can follow the federal result, too. For a closer look at the tax rules that apply to a rollover, including how Arizona treats a failed rollover, that breakdown covers the details.
If You Miss the Deadline
A blown deadline isn’t always final. The IRS lets people self-certify that they qualify for a late rollover when certain events caused the delay.
The approved list includes a few common problems. The financial institution made an error. A check was misplaced and never cashed. You or a family member became seriously ill, or a family member died. Your home was badly damaged. There are a handful of others, too. You give a signed letter to the company taking the deposit, not to the IRS. There’s no fee.
You’ll need to make the deposit soon after the problem clears. The IRS treats 30 days as meeting that standard. It can still review your claim later, so keep your records.
What the One-Rollover-Per-Year Rule Covers
This rule causes more confusion than it should. It only applies when an IRA pays you and you redeposit the money into an IRA within 60 days. You get one of those in any 12-month period.
It doesn’t apply to moving a 401(k) into an IRA. It doesn’t apply to direct transfers between IRA providers either. One more reason the direct path wins.
Before You Move Anything
A rollover isn’t the only choice. Some workplace plans offer lower-cost funds than an IRA. If you leave your job in or after the year you turn 55, your old plan may allow withdrawals without the early penalty. An IRA generally makes you wait until 59 and a half.
For a plain look at those trade-offs, Vanguard’s guide to 401(k) to IRA rollover rules lays out the benefits and the points to weigh. Then, if a rollover still makes sense, ask for a direct one and read the payee line on any check before you touch it.
