How to roll an old 401(k) into an IRA without getting hit by taxes

Two ways to move the money. One is safe and free. The other is a trap most people don't see coming until the IRS sends them a bill.

You changed jobs. The old 401(k) is still sitting at the old employer's plan provider. Or maybe a parent passed and you inherited an IRA. Or you finally retired and want to consolidate three accounts into one. Whatever brought you here, the goal is the same. Move retirement money from one tax-advantaged account to another, without losing a dollar to taxes or penalties.

It's easier than the financial industry makes it sound. There's exactly one right way to do it, and one way that gets thousands of people every year.

Direct rollover: the right way

A direct rollover, sometimes called a trustee-to-trustee transfer, moves your money from one plan custodian to another without you ever touching the funds. You open the new IRA first, then tell the old 401(k) provider to send the money directly to the new account.

The check, if there is one, is made out to the new custodian. Not to you. That single detail is the entire game.

Because the money never lands in your hands, no taxes are withheld, the 60-day clock never starts, and the once-per-year rule doesn't apply.1 You can do as many direct rollovers as you want. There is no penalty, no limit, no risk.

Indirect rollover: where the trap lives

An indirect rollover is when the old plan provider mails the check to you. You then have 60 days to deposit the full amount into the new IRA. If you do, no taxes. If you don't, the whole thing becomes a taxable distribution.

Two problems. Both are unforgiving.

First, when a 401(k) provider distributes money to you instead of another custodian, they are legally required to withhold 20 percent for federal taxes.2 That money goes to the IRS the day the check is cut.

Here's where it gets nasty. To complete the rollover tax-free, you have to deposit 100 percent of the original distribution into the new IRA within 60 days. Not 80 percent. 100 percent. That means you have to come up with the missing 20 percent from your own pocket and deposit it along with the 80 percent check you received. You'll get the 20 percent back the following year when you file taxes, but in the meantime your money is parked with the IRS.

Example. You roll $100,000. The 401(k) provider sends you a check for $80,000 and sends $20,000 to the IRS. To complete the rollover with zero tax hit, you have to deposit $100,000 into the new IRA within 60 days. You have to come up with the $20,000 from savings. If you can't, the IRS treats the unfunded $20,000 as a taxable distribution. You'll owe ordinary income tax on it, plus a 10 percent penalty if you're under 59 and a half.

The 60-day deadline is brutal

Sixty calendar days. Not business days. Not 60-ish. Sixty. Weekends and holidays count. Miss it by one day and the IRS treats the whole thing as a distribution.

There are limited hardship exceptions, but the IRS grants them sparingly. The cleaner path is just to never do an indirect rollover unless you absolutely have to.3

The once-per-year rule

If you do an indirect rollover from one IRA, you can't do another indirect rollover from any of your IRAs for 12 months. The rule covers all your IRAs combined, not per account.4 Direct rollovers and 401(k)-to-IRA rollovers don't count toward this limit. Only IRA-to-IRA indirect rollovers.

This rule exists because Congress noticed people were using the 60-day window as a free short-term loan. They'd take a distribution, use the money for two months, then put it back. The once-per-year limit shut that down.

The 60-second checklist for doing this right

Pick the receiving IRA first. Fidelity, Schwab, Vanguard, and Empower all do these for free. Don't open an account at the place your brother-in-law recommends just because. Pick on fees and fund selection.

Open the new IRA before you contact the old 401(k) provider

Call the old 401(k) provider and request a direct rollover (not a distribution)

Confirm the check or wire is being sent to the new custodian, not to you

If they insist on mailing it to you, ask them to make it payable to the new custodian, not to you personally (this is sometimes called "for the benefit of" or FBO)

Verify the money lands in the new IRA. Do not assume.

Common questions

Should I roll over an old 401(k) or leave it where it is?

Usually roll it over. Old 401(k) plans often charge higher fees, have limited investment options, and become a nuisance to manage. The exception is if the old plan has access to institutional share classes with very low expense ratios that you can't replicate in an IRA. That's rare but worth checking.

Should I roll to a traditional IRA or convert to a Roth?

Traditional IRA is the default if you want zero tax bill at rollover. Roth conversion makes sense if you're in a low tax bracket this year and expect higher rates later. You pay income tax on the converted amount in the year you convert, but all future growth is tax-free. This decision is worth a conversation with a fee-only planner.

What about company stock in the 401(k)?

If you hold appreciated employer stock in the 401(k), there's a special tax break called Net Unrealized Appreciation. Rolling it all into an IRA can cost you tens of thousands in lost tax benefits. Don't do anything until you talk to a planner or CPA about NUA.

What to do next

Find your old 401(k) statements. Note the current balance and the plan provider. Call the receiving institution you want to use (Fidelity, Schwab, Vanguard, whatever) and tell them you want to do a direct rollover. They handle the paperwork. They want your money. They're motivated to make it easy.

Whatever you do, do not let the old 401(k) provider mail you a check made out to you. That's the start of every horror story in this category.
