IRA & 401(k) Rollovers

Moving retirement money between accounts seems straightforward — until the IRS withholds 20%, your 60-day window expires, or you trigger the one-per-year rollover rule.

A rollover is the movement of funds from one retirement account to another, typically from an old 401(k) to an IRA or from one IRA to another. Rollovers are one of the most common transactions in retirement planning — and one of the most commonly mishandled.

The key distinction is between a direct rollover (money goes institution-to-institution without passing through your hands) and an indirect rollover (the check is made payable to you, and you re-deposit it yourself within 60 days). The difference matters enormously: direct rollovers are clean and free of withholding; indirect rollovers trigger mandatory 20% withholding on 401(k) distributions and carry a hard 60-day deadline.

A separate concept — the trustee-to-trustee transfer — moves IRA money directly between institutions without the owner ever touching the funds. Transfers are not technically rollovers and are not subject to the one-per-year rollover limit. For most IRA-to-IRA moves, a transfer is the cleaner option.

Key Concepts

Direct Rollover

The check is made payable to the new institution (e.g., "Fidelity FBO Your Name"), not to you. No taxes are withheld. No 60-day clock starts. This is the safest method for moving 401(k) money. When leaving an employer, always request a direct rollover — never take a check payable to yourself if you can avoid it.

Indirect Rollover & the 60-Day Rule

The check is made payable to you. You have 60 calendar days to deposit the entire amount — including any withheld — into a qualifying account. Miss the deadline and the distribution becomes taxable income, plus a 10% early-withdrawal penalty if you're under 59½. The IRS allows a one-time self-certification waiver for certain qualifying reasons. See also: Retirement Account Deadlines (60-day window and related rolling deadlines).

20% Mandatory Withholding

When a 401(k) or other employer plan makes an indirect distribution to you, the plan is required by law to withhold 20% for federal income tax. If your account balance is $100,000 and you take the check, you receive $80,000. To complete a tax-free rollover, you must deposit the full $100,000 — which means coming up with the $20,000 out of pocket until you get it back as a refund.

One-Per-Year IRA Rollover Rule

You may perform only one IRA-to-IRA indirect rollover every 12 months — across all your IRAs combined, not per account. This rule was tightened by the Tax Court in Bobrow v. Commissioner (2014). Violating it turns the second rollover into a taxable distribution. Trustee-to-trustee transfers are not counted — they're unlimited.

Trustee-to-Trustee Transfer

A transfer moves IRA assets directly from one IRA custodian to another. You never receive a check. There's no 60-day window, no withholding, and no one-per-year limit. For most routine IRA account moves — switching brokers, consolidating accounts — a transfer is simpler and safer than a rollover.

What Can Roll Where

Pre-tax 401(k) → Traditional IRA (tax-free). Roth 401(k) → Roth IRA (tax-free). Pre-tax 401(k) → Roth IRA (conversion — taxes due on pre-tax amount). IRA → IRA (same type, tax-free). IRA → 401(k) (if the plan accepts incoming rollovers). After-tax contributions in a 401(k) can roll to a Roth IRA tax-free.

Frequently Asked Questions

What's the difference between a rollover and a transfer?

A transfer moves IRA money directly from one custodian to another — you never touch the funds. There's no 60-day deadline and no one-per-year limit. A rollover involves receiving a distribution and then re-depositing it. Rollovers trigger the 60-day rule and the one-per-year IRA limit. For IRA-to-IRA moves, a transfer is almost always the better choice.

Can I roll a traditional 401(k) into a Roth IRA?

Yes — but it's a Roth conversion, not a tax-free rollover. The pre-tax portion of the 401(k) balance becomes taxable income in the year of the conversion. You'll owe ordinary income tax on the converted amount. There's no penalty (regardless of age), but the tax bill can be significant. This strategy can make sense in low-income years or early in retirement before Social Security or RMDs begin.

How does the 20% withholding work if I want to roll over my whole 401(k)?

If you request a distribution from a 401(k) payable to yourself, the plan must withhold 20%. If your balance is $50,000, you receive $40,000. To complete the rollover tax-free, you must deposit $50,000 into an IRA within 60 days — meaning you need to replace the $10,000 from other funds. The withheld $10,000 eventually comes back as a tax refund (assuming no tax was owed), but the timing mismatch causes problems. Avoid this entirely by requesting a direct rollover.

What if I miss the 60-day rollover deadline?

The distribution becomes a taxable event — plus a 10% early-withdrawal penalty if you're under 59½. The IRS does allow a self-certification waiver if you missed the deadline for a qualifying reason (illness, bank error, death of a family member, etc.). You certify the reason in writing to the receiving custodian and complete the rollover. This waiver is not a guarantee — the IRS can still audit — but it provides a safe harbor if your reason qualifies. For unusual situations, you can also request a Private Letter Ruling, but that's expensive and slow.

Can I roll an old pension (defined benefit plan) into an IRA?

Generally yes, for lump-sum distributions from a defined benefit plan — you can roll the lump sum into a traditional IRA. You cannot roll over ongoing monthly annuity payments — only distributions that qualify as eligible rollover distributions. If a pension offers both a lump sum and a monthly annuity, rolling the lump sum into an IRA gives you control over investments and RMD flexibility; taking the annuity provides a guaranteed income stream. This is a significant decision worth discussing with a financial advisor.

Does rolling over a 401(k) count toward the one-per-year IRA rollover limit?

No. The one-per-year rule applies only to IRA-to-IRA indirect rollovers. A rollover from a 401(k), 403(b), or other employer plan to an IRA does not count toward the limit. You could roll over five old 401(k)s to an IRA in the same year with no problem (as long as each is a direct rollover to avoid the 60-day clock).

Rollover rules are easy to get wrong.
