IRA distributions carry a 10% default federal withholding under IRS Publication 505, a prepayment you can raise, lower, or waive to 0% on Form W-4R before the money leaves the account.
Key Takeaways
- The default federal withholding on a nonperiodic IRA distribution is 10% of the taxable amount (IRS Publication 505 and Publication 590-B).
- You can elect any whole rate from 0% to 100% on Form W-4R before the distribution processes.
- Distributions delivered to an address outside the United States generally cannot go below the 10% floor.
- Eligible rollover distributions paid to you from a 401(k) carry a 20% mandatory federal withholding that cannot be waived.
- The 10% early withdrawal penalty under IRC section 72(t) is separate from withholding and applies to most IRA distributions before age 59.5.
- Federal withholding counts as paid evenly across the year under IRC section 6654(g), so a December election can cover earlier quarter shortfalls.
IRA Withholding by the Numbers (2026)
Figures reflect the 2026 federal rules cited in this article.
IRS Publication 505 sets a 10% default federal withholding on IRA distributions: when you take a nonperiodic (one time) IRA withdrawal and make no withholding election, the custodian withholds 10% of the taxable amount automatically. That 10% default is not mandatory. You can raise it, lower it, or waive it to zero by filing Form W-4R, and this page explains how the rule works for 2026.
Under IRS Publication 505, nonperiodic IRA distributions carry a 10% default federal withholding rate when the account owner makes no election. The 10% is a prepayment credited toward your total year tax, not the final tax. You can elect any rate from 0% to 100% on Form W-4R, though distributions delivered outside the US generally cannot go below 10%.
What is the default 10% withholding on IRA distributions?
The default 10% withholding is the federal income tax an IRA custodian automatically holds back from a nonperiodic distribution when you make no election. IRS Publication 505 and Publication 590-B confirm the rate is 10% of the taxable amount. A nonperiodic distribution is any one time or irregular IRA withdrawal, as opposed to a scheduled series of equal payments.
A traditional IRA distribution is taxable ordinary income in the year you receive it, so the IRS applies a backstop: if you say nothing, the custodian withholds 10% of the taxable amount for you (Source: IRS Publication 505, 2026; IRS Publication 590-B). The default also applies to a required minimum distribution and to a Roth conversion, since a conversion is a distribution for withholding purposes.
Is the 10% IRA withholding mandatory, or can I change it?
The 10% IRA withholding is a default, not a mandatory floor. You can change it, and you can waive it entirely down to 0%, by filing Form W-4R with your custodian before the distribution. The only common exception is a distribution delivered to an address outside the United States, where you generally cannot elect below 10% (Source: IRS Publication 505, 2026).
Many custodians let you set a standing withholding percentage, and some reset to 10% between distributions, so many retirees confirm their custodian has the current election on file before a large withdrawal.
How to change your rate with Form W-4R (elect 0% up to 100%)
Form W-4R is the IRS form used to elect a federal withholding rate on a nonperiodic IRA distribution. You can enter any whole percentage from 0% to 100% on the form, then give it to your custodian. The 2026 Form W-4R replaces earlier versions, so use the current year form to avoid a rejected election. Withholding is one way to address the Roth conversion estimated tax penalty.
- Get the current 2026 Form W-4R from your custodian or from IRS.gov.
- Enter the rate you want on the withholding line, any whole number from 0 to 100 (for example, 22 for 22%).
- To waive withholding entirely, enter 0 (subject to the outside the US exception below).
- Submit it to the custodian before the distribution processes; a late form applies to future withdrawals only.
- Keep a copy, and reconfirm the election each year if your custodian resets it.
Electing 100% is legitimate and useful late in the year, because federal law treats withholding as paid evenly across the year, a tactic covered in the safe harbor section below.
When you cannot go below 10% (distributions delivered outside the US)
You generally cannot elect below 10% withholding when an IRA distribution is delivered to an address outside the United States or its possessions. IRS Publication 505 restricts the zero and reduced rate election for payments sent abroad, so a US citizen or resident receiving distributions at a foreign address is held to at least the 10% default (Source: IRS Publication 505, 2026). Other rules that follow US retirees abroad are covered in expat retirement planning for US citizens.
The restriction follows the delivery address, not solely your residency, so retirees who use a foreign mailing address may need to plan for the 10% floor.
Why is it 10% for IRAs but 20% for 401(k) rollovers?
IRA distributions use a 10% default because they are nonperiodic distributions under IRS Publication 505. Eligible rollover distributions from a 401(k) or other qualified employer plan carry a 20% mandatory federal withholding instead, and that 20% cannot be waived if the money is paid to you rather than sent directly to another plan or IRA (Source: IRS Publication 505; IRS Publication 575, 2026).
An eligible rollover distribution paid to you carries the 20% mandatory withholding to discourage cash outs, and it is avoidable only through a direct (trustee to trustee) rollover. Once a check is cut to you, the 20% is gone even if you roll the money over within 60 days, and you must replace it from other cash to complete a full rollover.
| Feature | IRA nonperiodic distribution | 401(k) eligible rollover distribution paid to you |
|---|---|---|
| Default federal withholding | 10% | 20% |
| Can you waive it? | Yes, to 0% on Form W-4R | No, 20% is mandatory |
| Form used to set the rate | Form W-4R | Not adjustable (mandatory) |
| How to avoid withholding | Elect 0% | Use a direct (trustee to trustee) rollover |
| Authority | IRS Pub 505 / Pub 590-B | IRS Pub 505 / Pub 575 |
Is the 10% withholding the same as the 10% early-withdrawal penalty?
No. The 10% default withholding and the 10% early withdrawal penalty are two separate things that happen to share the same number. Withholding is a prepayment credited toward your tax. The early withdrawal penalty is an extra 10% additional tax under IRC section 72(t) that applies to most IRA distributions taken before age 59.5, on top of ordinary income tax.
A distribution before age 59.5 can involve both at once: the custodian may withhold 10% as a prepayment (credited on Form 1040), and you may separately owe the 10% additional tax (added on Schedule 2). Someone in a 22% bracket taking an early withdrawal could face 22% income tax plus the 10% penalty, roughly 32% of the amount, while only 10% was withheld by default.
How much should I actually have withheld from my IRA distribution?
Match your withholding to the tax the distribution will actually generate, which usually means your marginal federal bracket, not the 10% default. The 10% is only a prepayment credited toward your total year tax, not the final bill. If your top 2026 bracket is 22% or 24%, a 10% election leaves a shortfall that can trigger an underpayment penalty.
A traditional IRA distribution is ordinary income that stacks on top of Social Security, pensions, and other withdrawals, so many retirees use their 2026 marginal rate as the starting point, then add state tax and any 3.8% net investment income tax the added income triggers.
| 2026 taxable income (single) | 2026 taxable income (MFJ) | Marginal rate | Reasonable withholding starting point |
|---|---|---|---|
| Up to $50,400 | Up to $100,800 | 12% | 10% to 12% |
| $50,400 to $105,700 | $100,800 to $211,400 | 22% | 22% |
| $105,700 to $201,775 | $211,400 to $403,550 | 24% | 24% |
| $201,775 to $256,225 | $403,550 to $512,450 | 32% | 32% |
Bracket thresholds are rounded for illustration; confirm your own figures. Waiving withholding to 0% is allowed, but paying too little across the year can trigger an underpayment penalty under IRC section 6654. The 2026 standard deduction ($16,100 single, $32,200 MFJ, plus $2,050 single or $1,650 per spouse at age 65 and older) reduces the taxable amount before these rates apply.
Using IRA withholding to meet the estimated-tax safe harbor
Federal tax withheld from an IRA distribution is treated as paid evenly across the year under IRC section 6654(g), even if it all comes out in December. That timing rule lets a retiree cure a late year underpayment: withhold enough from a single year end IRA distribution to hit the estimated tax safe harbor, and the earlier quarters are generally protected from penalty.
The safe harbor is the smaller of 90% of this year tax or 100% of last year tax (110% if prior year AGI topped $150,000, or $75,000 if MFS). Quarterly estimates count only when actually paid, but withholding is spread evenly regardless of date. So a retiree who reaches December with no estimates paid can elect a high rate on Form W-4R against an IRA distribution (often the 2026 required minimum distribution) and satisfy the safe harbor, generally erasing the earlier quarter shortfalls.
What about state withholding on IRA distributions?
State withholding on IRA distributions varies by state and falls into three groups: some states require withholding whenever federal tax is withheld or above a threshold, some allow voluntary withholding, and states with no income tax require none. Your custodian applies your state of residence rules separately from the federal 10% default, so many retirees check both elections before a large withdrawal.
| State rule type | What it means | Examples (verify current rules) |
|---|---|---|
| Mandatory | State tax is withheld, often tied to whether federal tax is withheld | California, Maine, others |
| Voluntary | You may elect state withholding but are not required to | Many states |
| None | No state income tax, so no state withholding on IRA distributions | Florida, Texas, and other no income tax states |
State rules change and custodians maintain their own grids, so it is worth confirming your category at the time of the distribution. A retiree who moved recently may need to update the state of residence on file, because withholding follows the address the custodian has.
Roth conversions: should you withhold from the distribution?
For a Roth conversion, the general planning approach is to pay the tax from outside cash rather than by withholding from the converted amount. A conversion is a taxable IRA distribution, so any tax withheld from it reduces the dollars that reach the Roth and, if you are under 59.5, the withheld portion can itself be treated as an early distribution subject to the 10% penalty.
Example: converting $100,000 with 22% withholding sends $22,000 to the IRS and moves only $78,000 into the Roth. Paying the $22,000 from a taxable account instead lets the full $100,000 grow tax free inside the Roth. The math of how much to convert, and when the tax cost pays off, is covered in how much to convert to a Roth.
A conversion is irreversible, must be completed by December 31 to count for that tax year, and cannot be done from a required minimum distribution. See Q3 Advisors Roth conversion planning and the 2026 Roth conversion deadline.

Frequently asked questions
Is 10% withholding on IRA distributions mandatory?
No. The 10% federal withholding on a nonperiodic IRA distribution is a default that applies only when you make no election, per IRS Publication 505. You can raise it, lower it, or waive it to 0% by filing Form W-4R. The main exception is a distribution delivered outside the United States, where you generally cannot elect below 10%.
Can I change the 10% federal withholding on my IRA distribution?
Yes. File Form W-4R with your IRA custodian and enter any whole percentage from 0% to 100%. Submit it before the distribution processes so it applies to that withdrawal. Use the current 2026 Form W-4R, and reconfirm the election each year, because some custodians reset the account to the 10% default between distributions.
What is the default withholding rate for IRA distributions?
The default federal withholding rate for a nonperiodic IRA distribution is 10% of the taxable amount, under IRS Publication 505 and Publication 590-B. This is separate from eligible rollover distributions paid to you from a 401(k) or other qualified plan, which carry a 20% mandatory federal withholding that cannot be waived.
How much tax should I withhold from my IRA withdrawal?
Match withholding to the marginal bracket the distribution lands in, not the 10% default. If your top 2026 rate is 22% or 24%, withholding only 10% usually leaves a shortfall that can trigger an underpayment penalty. The 10% is a prepayment credited toward your total year tax, not the final tax.
Do I still owe taxes on an IRA withdrawal if 10% was withheld?
Possibly yes. The 10% withheld is a prepayment credited toward your total year tax liability, not the final tax. If the distribution is taxed at a higher marginal rate, you owe the difference when you file. If 10% exceeds your actual tax, the excess comes back as a refund. Withholding settles up on Form 1040. Other reasons a bill rises are covered in why taxes can be higher this year.
Is the 10% withholding the same as the 10% early withdrawal penalty?
No. The 10% default withholding is a prepayment credited toward your tax. The 10% early withdrawal penalty is a separate additional tax under IRC section 72(t) on most IRA distributions taken before age 59.5. They can both apply to the same early distribution, and the withheld 10% does not offset or replace the penalty.
What form do I use to change IRA withholding?
Use IRS Form W-4R to change federal withholding on a nonperiodic IRA distribution, electing any rate from 0% to 100%. For a periodic pension or annuity, the form is W-4P instead. For voluntary Social Security withholding, use Form W-4V. Give the completed form to the payer before the payment is processed. Applying these forms to required distributions is covered in how to pay taxes on RMDs.
