Three rates, decided by the type of payment

Form W-4R has one meaningful entry — a whole-number rate on line 2 — but the number you are allowed to write there is fixed by how the payment is classified before you ever see the form. The payer makes that call, and it is worth checking their answer, because the same dollar leaving the same 401(k) can be withheld at 10%, at 20%, or not at all.

Direct rollover

Trustee-to-trustee, nothing withheld

Payment type	Typical example	Withholding	What you may elect
Ordinary nonperiodic payment	An IRA withdrawal, a partial 401(k) payout you keep, an annuity payment that is not part of a series lasting more than a year. IRA distributions payable on demand are always nonperiodic.	10% default	You may enter any whole number from 0% to 100% on line 2, including "-0-".
Eligible rollover distribution paid to you	A payout from a 401(k), 403(b) or governmental 457(b) that could have been rolled over, but the cheque comes to you.	20% mandatory	You may elect more than 20% but never less — not even by rolling the money over within 60 days.
Direct rollover (trustee-to-trustee)	The plan sends the money straight to an IRA or another employer plan; you never take possession.	No current withholding	Nothing to elect. No Form W-4R is needed and no tax is withheld.
Periodic pension or annuity payment	Installments at regular intervals over a period of more than one year — a monthly pension, a life annuity.	Wage-style withholding	Wrong form: use Form W-4P instead.

One asymmetry catches people out. The 20% floor is a floor, not a rate — you can always ask for more, never for less. The 10% nonperiodic default is a default, not a floor — you can go all the way down to 0% or all the way up to 100%, as long as the payment is not being delivered outside the United States and its territories.

What is not an eligible rollover distribution

This is the list that decides whether 20% is mandatory. Form W-4R names eight payments that are excluded from the eligible-rollover withholding rules even when they come out of a qualified plan, so each of them is withheld as an ordinary nonperiodic payment at the 10% default and you are free to elect a different rate:

Qualifying "hardship" distributions
Distributions required by federal law, such as required minimum distributions
Distributions from a pension-linked emergency savings account
Eligible distributions to a domestic abuse victim
Qualified disaster recovery distributions
Qualified birth or adoption distributions
Qualified long-term care distributions
Emergency personal expense distributions

Most of the newer entries arrived with SECURE 2.0. The practical consequence is the same in every case: if the plan quotes you 20% on an RMD or a hardship withdrawal, the classification is wrong, and a Form W-4R electing a lower rate should be honoured.

The 2026 Marginal Rate Tables, and how to read them

Form W-4R prints a set of tables to help you pick a rate. They are not the ordinary bracket tables: each threshold is the bracket start plus the standard deduction for the filing status, because the table asks for total income from all sources, not taxable income. Someone single with $70,000 of income is in the 22% row here even though the 22% bracket itself begins much lower.

Single or MFS — total income over	MFJ or QSS — total income over	Head of household — total income over	Rate on every dollar more
$0	$0	$0	0%
$16,100	$32,200	$24,150	10%
$28,500	$57,000	$41,850	12%
$66,500	$133,000	$91,600	22%
$121,800	$243,600	$129,850	24%
$217,875	$435,750	$225,900	32%
$272,325	$544,650	$280,350	35%
$656,700	$800,900	$664,750	37%

Married filing separately uses the single column except at the top: the 37% rate starts at $400,450 instead. Derived from the 2026 brackets and standard deductions in Rev. Proc. 2025-32, which is exactly how the IRS builds the printed table.

The two-step lookup, worked

Both of these use the IRS's own examples. You are single and expect a taxable payment of $20,000, with the tax on your other income already covered.

Both rates match — enter that rate

Income without the payment is $70,000, which falls in the 22% row. Income including the payment is $90,000, still the 22% row. The two agree, so you write 22 on line 2.

Rates differ — blend them

Income without the payment is $60,000 (12% row); with it, $80,000 (22% row). $6,500 of the payment sits in the lower bracket and $13,500 in the higher one, giving $780 plus $2,970 = $3,750 of expected tax. That is 18.75% of the payment; round up and write 19 on line 2.

If you would rather not do the arithmetic, the IRS offers a deliberately conservative shortcut: take the rate that matches your total income including the payment. It usually over-withholds, which you get back as a refund.

Withholding is not the final tax

Form W-4R controls the payment sent to the IRS. It does not decide whether a distribution is taxable, eligible for rollover, subject to additional tax or partly nontaxable because of IRA basis.

Four things move between the rate on line 2 and the number on your return. Basis: nondeductible IRA contributions come out tax-free pro rata under the §72 rules, so a 10% withholding on a payment that is only partly taxable is an overpayment. The additional tax: a distribution before age 59½ without an exception carries a separate 10% additional tax that withholding does not automatically cover. Other income: a large withdrawal can push later dollars into a higher bracket, raise the taxable share of Social Security, or cross an IRMAA threshold two years out. Everything else on the return: credits, other withholding and estimated payments all land in the same reconciliation.

The underpayment rules are the reason to care about the gap rather than leave it to April. Withholding is treated as paid evenly across the year regardless of when it happened, so raising the rate on a December distribution is a legitimate way to cure a shortfall that an estimated payment made on the same day would not fix.

Situations with their own rule

You are living abroad

A US citizen or resident alien generally cannot elect below the 10% default — including "-0-" — on any payment to be delivered outside the United States and its territories.

You never returned the form

The default rate applies. Missing or incorrect SSN is worse: the payer must withhold 10% and is barred from honouring any request for less.

A payment that started before 2026

Your existing election, or the default that applied when it began, simply carries on. Nothing resets at year end; you have to file a new Form W-4R to change it.

Nonresident aliens and foreign estates

Form W-4R does not apply. Withholding follows Publication 515 and Publication 519, usually at a treaty or statutory Chapter 3 rate.

Non-taxable terrorist-attack disability payments

Enter "-0-" on line 2. Publication 3920 covers which payments qualify.

One election, many payments

Your choice generally carries forward to every future payment from the same plan or IRA. That is convenient for a repeating withdrawal and a trap for a one-off you sized for a single year.

W-4R questions

What is the default withholding rate on Form W-4R?

An ordinary nonperiodic payment generally defaults to 10%. A payee can usually choose another whole-number rate from 0% through 100%.

Why is 20% withheld from some rollover distributions?

An eligible rollover distribution paid to the participant is generally subject to mandatory 20% withholding. A direct rollover generally avoids current withholding.

Does withholding determine the final tax on the withdrawal?

No. Withholding is a payment toward tax. Final tax depends on taxable basis, income, filing status, penalties, credits and other payments.

Can I have zero tax withheld from an IRA withdrawal?

Yes for an ordinary nonperiodic payment: enter "-0-" on line 2 of Form W-4R. Two exceptions. Payments to be delivered outside the United States and its territories generally cannot go below the 10% default. And an eligible rollover distribution paid to you cannot go below 20% however you fill the form in.

What happens if I never send Form W-4R to my IRA custodian?

The payer applies the default: 10% on an ordinary nonperiodic payment, 20% on an eligible rollover distribution. The same 10% floor is forced — and requests for a lower amount cannot be honoured — if you give no SSN or the IRS tells the payer the SSN you gave is wrong. For payments that began before 2026, an election you already made stays in effect until you file a new Form W-4R.

Is a required minimum distribution an eligible rollover distribution?

No. An RMD is a distribution required by federal law, so it is outside the 20% rule and is withheld as an ordinary nonperiodic payment. Hardship distributions, qualified birth or adoption distributions, emergency personal expense distributions, qualified disaster recovery distributions, qualified long-term care distributions, pension-linked emergency savings account distributions and eligible distributions to a domestic abuse victim are also excluded.

How do I choose a rate instead of taking the default?

Use the Marginal Rate Tables printed on Form W-4R. Find the rate for your total income without the payment, then the rate for your total income including the taxable payment. If the two rates match, enter that rate. If they differ, tax the part of the payment sitting in each bracket, add the two, divide by the payment and round up to the next whole number.

I want to roll the money over — how do I avoid the 20%?

Ask for a direct rollover. If the plan pays you instead, 20% is withheld and you have 60 days to roll over the distribution; to roll the whole amount you must replace the withheld 20% out of your own pocket and wait for it to come back as a refund. Anything you do not replace counts as a distribution and can trigger the 10% additional tax if you are under 59½.

Can a nonresident alien use Form W-4R?

No. Payments to nonresident aliens and foreign estates are outside Form W-4R; the payer follows the Chapter 3 rules in Publication 515 and Publication 519 instead.
