Do I Have to Pay Taxes on a 401(k) Rollover From a Former Employer?

A direct 401(k) rollover from a former employer to a traditional IRA is not taxable. The money moves trustee-to-trustee and no withholding applies. An indirect rollover is taxable if you fail to redeposit the full balance, including the mandatory 20% withheld, within 60 days.

The 20% figure catches people off guard because it is not a penalty. Under IRC §402(c)(1), a direct rollover is exempt from mandatory federal withholding; an indirect one is not. Your former plan administrator hands you a check for 80% of your balance and sends the other 20% to the IRS as an estimated tax payment. That money is yours, but only after you file.

To complete an indirect rollover without a tax bill, you write a check to the receiving IRA for the full original balance, including the 20% you never received. If your account held $40,000, the check is $40,000, not $32,000. The $8,000 withheld shows up as a credit on your return, so you are made whole eventually, but only if you front it.

Miss the 60-day window and the withheld portion becomes a taxable distribution. Add the 10% early-distribution penalty under IRC §72(t) if you are under 59½, and that $8,000 on a $40,000 balance costs roughly $2,800 in tax plus $800 in penalty at a 22% bracket. The rules are documented in IRS Notice 2009-68, which plan administrators are required to send you within 30 days of a distribution.

• Direct rollovers avoid withholding: A trustee-to-trustee transfer from a 401(k) to an IRA triggers no 20% mandatory federal withholding under IRC §402(c)(1) and has no 60-day deadline.
• Indirect rollovers require replacement: You must redeposit the full distributed amount, including the 20% sent to the IRS, within 60 days or the withheld portion is taxed as income.
• Under 59½ adds 10%: Missing the 60-day deadline means the taxable portion also faces a 10% early-distribution penalty under IRC §72(t).
• One indirect rollover per year: Per IRS Announcement 2014-15 and IRC §408(d)(3)(B), you may do only one indirect 60-day rollover across all your IRAs in any 12-month period.
• Roth conversions differ: A direct rollover from a 401(k) to a Roth IRA is taxable in the conversion year, but no 20% withholding applies and there is no 60-day deadline.

Direct vs. indirect rollover: what's the actual difference?

A direct rollover is a trustee-to-trustee transfer. You fill out the receiving plan's paperwork, name your former employer's 401(k) provider as the sending institution, and the money moves between accounts electronically. The check, if one is printed at all, is made payable to something like "Fidelity FBO Jane Smith, Traditional IRA." It never becomes yours to deposit, which is exactly why $0 is withheld and $0 is taxable. The 401(k) administrator reports the distribution on Form 1099-R with distribution code G, and the receiving IRA custodian files Form 5498 confirming the deposit. Those two forms are what the IRS matches.

An indirect rollover looks almost identical from your side of the desk and behaves nothing like it. The plan pays the balance to you personally, which means it is a distribution under IRC §402(c)(1). Federal law requires the plan to withhold 20% of the taxable amount before the check is cut, so a $40,000 balance arrives as $32,000. You then have 60 days from the date of distribution, per IRC §402(c)(4), to deposit the entire $40,000 into an eligible IRA or new employer plan. The $8,000 the IRS is holding has to come from your savings, your checking account, a bonus, wherever you can find it. Redeposit $32,000 and the missing $8,000 is treated as a taxable distribution, subject to ordinary income tax and a 10% additional tax under IRC §72(t) if you are under 59½.

The withholding itself is not a penalty, and this is where most people misread their own paperwork. It is a prepayment of estimated tax, credited against whatever you owe when you file. Rebuild the full $40,000 inside the 60 days and the $8,000 simply comes back to you as part of your refund — no tax, no penalty, nothing lost except the few weeks the government held your money. Fail to rebuild it and the same $8,000 becomes the worst possible outcome: you pay income tax on it at your marginal rate, plus 10%, plus you are still out the cash. On a $40,000 balance belonging to someone in the 24% bracket, that is roughly $1,920 in federal tax and $800 in penalty on money you never actually received.

One number worth checking before you decide: Vanguard's How America Saves 2026 puts the median 401(k) balance for recent job-changers at $12,000 to $25,000. For a $15,000 balance, the withholding is $3,000 — manageable for many households — but the real risk is the calendar. IRS Notice 2009-68 spells out the 60-day rule, and Announcement 2014-15 lists the 11 narrow grounds on which the IRS will grant a late-rollover waiver, most of them involving death, disability or a bank error you can document. "I forgot" is not on the list. If the money is already sitting in your account as a check, the cleanest fix is usually to open the receiving IRA today and complete the deposit the same week, not the same quarter.

What happens if you miss the 60-day deadline?

On day 61, the 20% your plan administrator sent to the IRS stops being a placeholder and becomes income. Say you moved $50,000 from a former employer's 401(k) and received a $40,000 check with $10,000 withheld. Roll the $40,000 into a Traditional IRA within 60 days and you've still triggered a $10,000 taxable distribution for that calendar year, reported in Box 1 and Box 2a of the Form 1099-R your old plan issues. The remaining $40,000 rolls over tax-free under IRC §402(c)(1), which is why so many people assume the whole thing was clean.

Then the penalty lands on top. Under IRC §72(t), that $10,000 carries an additional 10% tax — $1,000 — if you're under 59½ in the year of the distribution, on top of whatever ordinary income tax your bracket produces. A 24% marginal rate means roughly $3,400 gone on money you never touched. Form 5329 is where you report and compute the additional tax; the IRS will generally catch the discrepancy when it matches the 1099-R against your return, and by then the 60 days are long gone. What commonly goes wrong is subtler: people miss the deadline not because they forgot, but because a check made out to the IRA custodian sat in a drawer while they waited on account paperwork. The clock runs from the date of distribution, not the date you decide to act.

Relief exists, but it is narrow. You can request a private letter ruling asking the IRS to waive the 60-day requirement under IRC §408(d)(3)(B), and the agency has granted waivers for death, disability, hospitalization, incarceration, postal error, and a handful of other situations it lists in Revenue Procedure 2003-16. A ruling costs thousands in user fees and professional time, takes months, and is not guaranteed. Since 2016 the IRS has also offered self-certification — Form 14568-A, filed with your return — for eleven specific reasons including casualty, postal mishap, and a financial institution's error, but if the IRS later challenges it you'll need actual documentation, not a plausible story. Neither route helps the person who simply let the window close.

Here is the part worth saying without hedging. Most articles tell you a rollover is not taxable. That is true only of a direct rollover, where the check goes trustee-to-trustee and $0 is withheld. An indirect rollover is taxable by default unless you replace the withheld 20% with your own money inside the same 60 days and roll the full original balance — $50,000 in the example above, not $40,000. The trap is never the rollover. It is the withholding you never see, sitting with the government as a credit against next April's bill while the calendar quietly runs out.

How the 20% mandatory withholding actually works

The 20% withholding applies only when the money passes through your hands. If your former employer's plan sends a check made out to you, or wires the balance into your personal checking account, that is an indirect rollover, and federal law requires the plan administrator to withhold 20% of the taxable amount before the money ever reaches you. The administrator does this whether or not you intend to redeposit the funds. Your intention is irrelevant to them.

Direct rollovers sidestep all of it. When the check is made payable to the receiving institution — "XYZ Custodian FBO John Smith IRA" — or sent by wire directly, the plan withholds $0 and reports the distribution as taxable in box 2a only to be offset by the rollover on your return. The procedure below is for the indirect case, where the cash lands with you first.

1. Confirm what was withheld before you move anything. Look at the statement or distribution notice from the administrator. If the gross distribution was $60,000, you received roughly $48,000. The $12,000 difference is the 20% mandatory federal withholding. That $12,000 is gone from your account and is now a credit sitting with the IRS under your Social Security number. Do this the same week the distribution arrives.
2. Open or designate a Traditional IRA at a brokerage that accepts incoming rollovers — Vanguard, Fidelity, Schwab, any of them work. Have the account number ready. This takes 15–30 minutes online.
3. Deposit the full amount you received, not a cent less, by the 60th day from the distribution date. The clock starts on the date the plan issued the distribution, not the date you noticed it or the date the check cleared. IRC §402(c)(4) sets the 60-day window and the IRS does not extend it for forgetfulness.
4. Add the withheld 20% out of your own pocket. This is the step people botch, because their bank balance is now $12,000 lighter and their instinct is to roll over only what they can see. You must contribute the $48,000 plus $12,000 from your checking or savings account to reach the full $60,000 inside the IRA. The withheld amount is not redeposited by the plan and no one tells you it is your responsibility.
5. Save the paperwork: the plan's distribution statement, the receiving custodian's deposit confirmation, and a bank statement showing the extra $12,000 leaving your account. The receiving custodian will report the deposit on Form 5498 in the following May. The plan reports the gross distribution and the withholding on Form 1099-R, copies of which go to you and to the IRS.
6. File on time and claim the withheld amount as a payment. When you file your 1040, the $12,000 shows up as federal tax already paid, exactly like withholding from a paycheck. If your total tax liability for the year is below what was withheld across all sources, you get the difference back as a refund. If it is higher, you owe the balance. Either way the credit appears on the return, not in your IRA.
7. Check the 12-month rule if you might do a second IRA-to-IRA rollover within the year. IRC §408(d)(3)(B) allows one indirect rollover per 12-month period per IRA owner. A direct rollover from a 401(k) to an IRA does not count against this limit, but a subsequent indirect IRA-to-IRA move does. IRS Announcement 2014-15 restated the restriction after years of confusion.

Where this goes wrong, in the order it usually happens. Someone rolls over only the $48,000 they received, assuming the government's piece will follow. It will not. The $12,000 becomes a taxable distribution, taxed at their marginal rate — at a $60,000 gross that is often 22% federal plus state, so roughly $2,640 on top of losing the $12,000 — and because the reader is 35 to 55 and almost certainly under 59½, IRC §72(t) adds a 10% early-distribution tax of about $1,200. Form 5329 is where that penalty gets reported and calculated. Worse, the withheld $12,000 is no longer inside a retirement account earning anything, and there is no mechanism to put it back once the 60 days elapse. The IRS has published a self-certification procedure for a handful of narrow reasons — a plan error, a death in the family, a casualty — via IRS Notice 2009-68, but "I didn't know" is not on the list and never has been.

One honest caveat: if you were laid off in 2026 and received unemployment compensation, you may not need the withheld 20% back as a credit at all — you may prefer to leave it with the IRS and apply it against next April's bill. That is a cash-flow question, not a rollover-compliance question, and it does not change the requirement to deposit the full $60,000 inside the IRA within 60 days.

Tax forms you'll receive: 1099-R, 5498, and 5329

The paperwork shows up months apart, which is why people panic in February and relax in May for no good reason. Your former 401(k) provider mails Form 1099-R by 31 January, and it reports the full gross distribution — Box 1 — whether or not a dollar of it was taxable. If you did a direct rollover, Box 2a reads $0 and Box 7 carries code G. If you took the money personally, Box 2a typically shows the taxable portion and Box 7 carries code 1 (or code 7 if you were 59½ or older), and the 20% already sent to the IRS appears in Box 4.

The receiving institution — your IRA custodian — files Form 5498, usually by 31 May, showing the rollover contribution. That form exists so the IRS can match the 1099-R outflow against the 5498 inflow. When the numbers don't reconcile, the automated notice follows.

The bottom three rows are the ones that cost money, and the gap between them is the whole point: row one is the outcome you want, row five is what you get if you miss the 60-day window on an indirect rollover, and row six is the escape hatch you almost certainly don't qualify for in this scenario. Form 5329 exceptions under IRC §72(t) cover things like disability, a qualified birth or adoption (up to $5,000 per child), or a terminal illness — not "I forgot to move the money in time." The IRS has granted late-rollover relief in a handful of private letter rulings, and Revenue Procedure 2020-17 created a self-certification path for 11 specific reasons including a casualty, a postal error, or a financial institution's mistake, but a missed deadline caused by your own inattention is not on that list. If you did a direct rollover, the 1099-R and the 5498 are the only two forms you'll ever see, and neither one changes your taxable income by a cent.

The one-rollover-per-year rule most people don't know

IRC §408(d)(3)(B) limits you to one indirect rollover per 12-month period, and the clock is measured from the date you received the first distribution, not the date you redeposited it. IRS Announcement 2014-15 settled a long-running dispute about scope: the limit applies once per IRA owner across all your IRAs combined, not once per account. If you hold a Traditional IRA at Fidelity and another at Vanguard, that is still a single bucket for this purpose. Two indirect rollovers inside 12 months means the second one is not a rollover at all — the full amount is an ordinary taxable distribution, and if you are under 59½, IRC §72(t) adds 10% on top. On a $30,000 second rollover in the 22% bracket, that is $6,600 in income tax plus a $3,000 penalty.

Direct rollovers are exempt from this entirely. A trustee-to-trustee transfer from your former employer's 401(k) plan to a Traditional IRA has no 12-month cap, no waiting period, and $0 withheld — you could execute ten of them in a calendar year and the IRS would not care. The same is true of a direct rollover into a Roth IRA, a plan-to-plan move, or a 401(k) to Traditional IRA transfer done by check made payable to the receiving custodian "FBO" you. The trap only springs when the money physically passes through your hands.

Where the two rules collide

The 20% mandatory withholding and the 12-month limit are separate constraints that both bite on indirect rollovers, and people tend to discover the second one only after tripping the first. You miss the 60-day deadline on a $25,000 indirect rollover, replace the $5,000 withheld out of pocket to make the math whole, and think you are finished. Eight months later you take a second distribution from a different IRA and roll it over within 60 days, correctly replacing the withheld amount — and the IRS treats that second one as fully taxable, because it fell inside the 12-month window. Form 5329 is where the 10% additional tax gets reported when you file. There is no partial relief built into the statute, and the IRS grants a waiver of the 60-day deadline under Revenue Procedure 2016-47 only for a defined list of hardships; being unaware of the 12-month rule is not one of them.

The practical fix costs nothing. Route every rollover directly between institutions and the 12-month cap never applies to you. If your former employer insists on mailing a check — some small plan administrators still do — confirm before it arrives that the payee line names the receiving custodian, not you.

When a 401(k) rollover to a Roth IRA is taxable — and when it's not

A direct rollover from a 401(k) to a Roth IRA is a taxable event, and there is no way around it. The money leaving the plan was never taxed, and putting it into a Roth means you are electing to pay tax now instead of at withdrawal. Your former employer's plan administrator will code the 1099-R as a taxable distribution, and the full converted amount lands on your Form 1040 as ordinary income for the year of the transfer. On a $60,000 balance, a married couple filing jointly in the 22% bracket is looking at roughly $13,200 in federal tax, before any state hit. What does not happen is withholding. The 20% mandatory federal withholding under IRC §402(c)(1) applies to indirect rollovers paid to you personally, not to direct trustee-to-trustee transfers. A direct conversion arrives at the Roth custodian at 100% of the balance.

That distinction matters because the tax bill is yours to settle separately, and the honest answer to "should I withhold from the conversion?" is: only if you have no other way to pay it. If you tell the plan to send $60,000 to the Roth and withhold $12,000 for taxes, you have converted $48,000 and paid $12,000 of tax with money that would have compounded tax-free for the next 25 years. Run it the other way — convert the full $60,000 and pay the $13,200 from a savings account — and every dollar of that $60,000 is inside the Roth. The trade-off resolves differently for the two main cases. If you are 35 with $200,000 in cash reserves and a $60,000 balance, pay from outside funds. If you are 54, converting $250,000 in a single year, and have no liquid savings, withholding a slice is worse than converting nothing at all — in that case, convert in smaller annual tranches instead.

For anyone under 59½, there is a second trap that has nothing to do with the conversion itself. Money withheld from a direct transfer never happened, so there is no penalty. But if the plan pays you and you fail to replace the withheld 20% within 60 days, that shortfall is a distribution, taxed as ordinary income and hit with the 10% additional tax under IRC §72(t) — roughly $1,200 on a $12,000 withholding, on top of the income tax. The taxed conversion amount and the early-distribution penalty are two separate lines on your return, and Form 5329 is where you report the second one. Vanguard's 2026 How America Saves puts the median 401(k) balance for recent job-changers at $12,000–$25,000, which means the 10% penalty on a botched indirect rollover of that size runs $240–$500. Small. The income tax on the same amount is not.

Special rules if you were born before January 2, 1951

There is a narrow group of people for whom a 401(k) rollover can create a tax bill that would not otherwise exist, and they were all born before January 2, 1951. Under the original 401(k) regulations, a participant in a workplace plan who is still working for the sponsoring employer can defer Required Minimum Distributions on that employer's plan until retirement — the "still working" exception. IRAs have no such exception. The year you turn 73 (or 75, depending on your birth year under SECURE 2.0), an IRA demands an RMD whether or not you have stopped working.

That mismatch is the trap. Say you turn 75 in 2026 and are still on payroll at the employer whose plan holds your 401(k). You retire from a previous job, roll that old 401(k) into a Traditional IRA in November, and the IRA now has an RMD obligation for the following calendar year. If you roll over in December, you have roughly four weeks before the first distribution is due — and if you miss it, the penalty under IRC §4974 is 25% of the shortfall, reduced to 10% if corrected within a two-year window. The same balance left in the 401(k) would have generated no RMD at all while you kept working.

Timing the rollover around the RMD deadline

Two dates matter. RMDs must be taken by December 31 of each year; there is no extension, even if you file your return on October 15 of the following year. And any RMD due from the 401(k) itself must come out of the plan before the rollover — you cannot roll the RMD amount to an IRA, and attempting to do so makes it a taxable distribution that cannot be undone. Roll the remaining balance to an IRA in January, not December, and you buy yourself a full calendar year before the IRA's first RMD is due.

The exception worth knowing: if the receiving IRA is a Roth IRA and you are the original owner, there are no RMDs during your lifetime at all, because Roth IRAs are not subject to the lifetime RMD rules. A Roth conversion from a pre-tax 401(k) is a taxable event in the year of conversion, so it is not a free move — but for someone in this birth cohort who plans to keep working past 75, converting in a low-income year can cost less than the RMDs an IRA would force out every year afterward. Run the numbers for both years before you decide which account type gets the money.

How to execute a direct rollover in 5 steps (and avoid the 20% trap)

A direct rollover applies when the money moves from your former employer's 401(k) plan to a Traditional IRA without ever passing through your hands as a payable-to-you check. This is the only version of the transaction where 20% mandatory federal withholding never applies. The procedure below assumes you have the plan's phone number or online portal login, roughly 30-45 minutes of total phone and computer time over two or three weeks, and either a brokerage account or the willingness to open one. Nothing here costs you money. If a provider quotes a fee, ask them to itemise it against your plan's summary plan description.

1. Open a Traditional IRA at a low-cost custodian before you call the 401(k) provider. Vanguard, Fidelity, and Schwab are the three that handle rollover paperwork without friction; all three charge $0 for the account itself and $0 commission on the rollover. You need the account number in hand before requesting the distribution, because the 401(k) provider will ask for it in writing. Online account opening takes 10-15 minutes; funding can wait until the check arrives. Use a Traditional IRA, not a Roth IRA, if you want zero taxable income from this move. A conversion to Roth is a separate, taxable event.
2. Gather the exact titling the IRA custodian uses. That means the full account registration, typically "Vanguard FBO [Your Name] Traditional IRA" or equivalent. Misspelling your own name here is the single most common paperwork rejection.
3. Request a direct rollover from the 401(k) provider and have the distribution made payable to the IRA custodian, not to you. Say the words "direct rollover" on the call. If the check is written to you personally, even for one day, you have an indirect rollover, 20% will be withheld under IRC §402(c)(1) mechanics, and you have 60 days under IRC §402(c)(4) to replace the withheld amount from your own bank account. On a $25,000 balance that is a $5,000 gap you have to front. Call length: 15-30 minutes. Some providers (Fidelity-administered plans especially) can do the transfer electronically via ACATS-style delivery in 5-7 business days.
4. Confirm the delivery method. Mailed check to the custodian's rollover address, or a wire. Wires typically cost $25-40 and move same-day; paper checks take 7-14 business days via USPS. If you ask for a wire, get the custodian's inbound wire instructions before you hang up, and read the routing number back to the rep.
5. Watch for the check in your IRA account, not your mailbox. If a check arrives at your home address, do not deposit it. Call the 401(k) provider and have them stop and reissue it payable to the custodian. Depositing a check made out to you converts the whole transaction to an indirect rollover.
6. Confirm no taxes were withheld once the funds land. Log in to the IRA and verify the deposit equals the full distribution amount. If the 401(k) statement shows a 20% federal withholding line, the provider treated it as indirect, and you now have 60 days from the distribution date to deposit the missing 20% into the same IRA from personal funds. Mark that date on your calendar. Missing it triggers ordinary income tax on the withheld portion plus the 10% additional tax under IRC §72(t) if you are under 59½.
7. Report the rollover on your tax return the following spring. You will receive Form 1099-R from the 401(k) provider showing the gross distribution in Box 1 and, for a clean direct rollover, code G in Box 7 with $0 in Box 2a. The IRA custodian sends Form 5498 in May. On your Form 1040 you enter the amount on line 5a (gross) and $0 on line 5b (taxable), with the word "ROLLOVER" written next to 5b. No tax is due. The reporting is not optional — the IRS matches 1099-Rs to returns automatically, and an unreported gross distribution generates a CP2000 notice within 12-18 months.

The failure mode to plan around is a provider that issues the check to you anyway, usually because the phone rep defaults to the path their system makes easiest. This happens more often at smaller plan administrators and at plans using older recordkeeping software. If it does, you are not stuck — you have 60 days from the distribution date to deposit the full gross amount into the IRA, including the 20% you never received. For someone with a $12,000 balance (roughly the median for recent job-changers per Vanguard's How America Saves 2026), that means finding $2,400 in cash within two months. For a $250,000 balance, it means $50,000. The IRS grants waivers for a handful of specific reasons — bank errors, postal failures, death or serious illness — and, since Revenue Procedure 2016-47, will issue a self-certification letter for about 11 listed hardship categories. "I didn't know" is not one of them.

Frequently Asked Questions

Do I have to pay taxes on a 401k rollover from a former employer?

No tax is owed if the money moves directly from your former employer's plan to a traditional IRA or another 401(k). The IRS treats a direct rollover as a non-event: no withholding, no 1099-R taxable amount, nothing to report beyond the distribution code. You owe tax only when the check is made payable to you personally and the full amount is not redeposited within 60 days.

What is the 60-day rule for 401k rollovers?

You have 60 calendar days from the date you receive an indirect distribution to deposit the entire amount into a qualifying retirement account. That means the gross figure, not what landed in your hand. If your plan sent $50,000 and withheld 20 percent, you must redeposit $50,000 within the window. The 60th day is a hard deadline; the IRS grants extensions in only a narrow set of circumstances, such as a documented postal error or a hospital stay.

Can I roll my 401k into an IRA without paying taxes?

Yes. A direct trustee-to-trustee transfer from a 401(k) to a traditional IRA is not a taxable event. Ask the plan administrator to issue the check to the receiving custodian, for example "Fidelity FBO Jane Doe IRA," and it never counts as a distribution to you. There is no 20 percent withholding and no 60-day clock, because you never took constructive receipt of the money.

What happens if I miss the 60-day rollover deadline?

The entire distribution becomes ordinary income in the year it was paid, reported on a 1099-R with distribution code 1. On a $50,000 balance in the 22 percent bracket, that is roughly $11,000 in federal tax. If you were under age 59½ on the distribution date, add a 10 percent early-withdrawal penalty on the taxable amount, another $5,000 in that example. State tax may apply on top.

Do I get the 20% withholding back when I file my taxes?

Only if you make the rollover whole from other funds. Replace the withheld amount out of pocket, deposit $50,000 when the plan withheld $10,000, and the $10,000 is credited against your total tax liability on Form 1040. If you roll over just the $40,000 you received, the missing $10,000 is taxable income and, if you are under 59½, subject to the 10 percent penalty as well.

Can I do more than one 401k rollover per year?

Direct rollovers are unlimited. Move four old 401(k) accounts into one IRA in the same calendar year and the IRS does not care. The restriction applies only to indirect rollovers, where you personally receive the funds: one per 12-month period, counted across all your IRAs, not per account. Exceed it and the second distribution is taxable, and the 10 percent penalty applies if you are under 59½.
