When you roll over a 401k, the IRS requires your plan administrator to withhold 20% of the distributed amount for federal taxes on indirect rollovers — unless you complete a direct rollover. In 2026, federal withholding rules remain the same, but state withholding rates vary widely. Understanding both helps you avoid unexpected tax bills and penalties.

How Federal Tax Withholding Works on 401k Rollovers in 2026
The IRS distinguishes between two types of rollovers, and the type you choose determines how much withholding applies.
Direct Rollovers: Zero Withholding Required
In a direct rollover, your plan administrator transfers funds directly to your new IRA or employer plan. Because you never physically receive the money, federal withholding does not apply. This is the cleanest, lowest-cost way to move your 401k balance. No taxes are withheld, and your entire balance continues growing tax-deferred without interruption.
Indirect Rollovers: Mandatory 20% Federal Withholding
In an indirect rollover, your employer writes you a check for the distribution. The IRS mandates that 20% be withheld immediately for federal income taxes. Here is where it gets costly: if you want to complete a full rollover and avoid taxes, you must deposit 100% of the original balance — including the 20% already withheld — into your new account within 60 days. That means you must cover the withheld amount out of pocket.
Example: You have a $100,000 401k balance. Your employer withholds $20,000 and sends you a check for $80,000. To complete a full rollover, you must deposit $100,000 within 60 days. If you only deposit $80,000, the missing $20,000 is treated as a taxable distribution — and if you’re under age 59½, it also triggers a 10% early withdrawal penalty of $2,000 on that amount.

State Tax Withholding on 401k Rollovers by State in 2026
Federal withholding is only part of the story. Many states impose their own mandatory withholding rules on retirement distributions, and these rules vary dramatically.
States With No Income Tax (No Withholding)
As of 2026, residents of Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming pay no state income tax. If you live in one of these states, state withholding on a 401k rollover does not apply.
States With Mandatory Withholding
States like California, New York, Minnesota, and Oregon require withholding on retirement distributions unless you opt out. California, for example, mandates 10% state withholding on top of federal withholding for non-periodic distributions unless the recipient submits a withholding election form. Minnesota applies a default rate of 6.25%. These amounts stack on top of the 20% federal withholding in indirect rollover situations, meaning the total amount withheld could approach 30% or more of your distribution.
States That Allow Opt-Out
Several states permit you to waive state withholding by filing the appropriate form with your plan administrator. If you are completing a direct rollover, state withholding typically does not apply regardless — but it is always worth confirming with your plan’s custodian before initiating the transfer.
Because state rules change frequently, always verify your state’s current withholding rate with your plan administrator or a licensed tax professional before initiating any distribution.
The 60-Day Rollover Rule and Withholding Costs in 2026
The 60-day rollover rule is closely tied to withholding costs. Once your employer issues a distribution check, you have exactly 60 calendar days to deposit the full original amount — not just the net check amount — into a qualifying retirement account.
What Happens If You Miss the 60-Day Deadline
Missing the deadline converts the entire undistributed amount into ordinary taxable income in the year of distribution. In addition to federal and state income taxes, taxpayers under age 59½ owe an additional 10% early withdrawal penalty on the taxable portion. The total tax cost can easily reach 30–40% of the original balance depending on your income bracket and state of residence.
IRS Waiver of the 60-Day Rule
The IRS does grant hardship waivers of the 60-day rule in limited circumstances, such as errors made by the financial institution. Automatic waivers are available if the failure was due to bank errors, death, hospitalization, or federally declared disasters. However, obtaining a waiver requires documentation and is not guaranteed. The safest strategy is always to use a direct rollover and avoid the 60-day window entirely.

Custodian Fees and Withholding: What Comes Out of Your Rollover
Beyond IRS and state withholding, some custodians charge fees directly related to processing a rollover distribution. These can include distribution fees (typically $25–$75), outgoing wire transfer fees ($15–$30), and medallion signature guarantee fees if required. Some plans also charge account termination fees ranging from $50 to $150.
How These Fees Interact With Withholding
Plan fees are generally deducted before the distribution amount is calculated, which means withholding is applied to a slightly smaller net balance. If your plan charges a $75 termination fee on a $100,000 balance, federal withholding of 20% would apply to $99,925 in an indirect rollover scenario — a small difference, but worth knowing when calculating your 60-day repayment obligation.

Frequently Asked Questions
Is the 20% federal withholding on 401k rollovers mandatory in 2026?
Yes, the mandatory 20% federal withholding applies to indirect rollover distributions in 2026. It is not optional. The only way to avoid it is to request a direct rollover, where funds move directly from your old plan to your new account without passing through your hands.
Can I get the withheld 20% back?
Yes, but only if you deposit the full original balance — including the withheld 20% — into a qualifying account within 60 days. The withheld amount is credited against your annual tax liability, and any overpayment is refunded when you file your federal tax return.
Does my state withhold taxes on 401k rollovers?
It depends on your state. Nine states have no income tax and therefore no withholding. Other states apply rates from roughly 5% to 10%, with some allowing opt-out elections. Always confirm your state’s current rules with your plan administrator before initiating a distribution.
Are there fees charged by my 401k plan when I roll over?
Many plans charge distribution, termination, or wire transfer fees ranging from $25 to $150. These fees are deducted from your balance before the rollover proceeds are calculated. Review your plan’s Summary Plan Description for the exact fee schedule.
How long does a direct rollover typically take in 2026?
Most direct rollovers take between 5 and 15 business days, depending on your plan administrator’s processing time and the receiving institution’s requirements. Some custodians issue checks payable to the new institution rather than wiring funds, which can add several days for mail delivery and processing.
