Using IRA Withholding to Fix an Underpayment Penalty

By Tom, CPA · Updated October 25, 2026

TL;DR: Federal tax withheld from an IRA distribution is treated as paid in equal amounts on each estimated tax due date, even if it was withheld in December. Retirees can use this to cover missed or short estimated payments. Under 59½, a variation uses a 60-day rollover, which carries real risks.

The IRS treats withholding as if it arrived evenly all year. December miracles are possible. For retirees who forgot or underpaid quarterly estimates, this single rule can erase an underpayment penalty without filing extra forms.

This guide explains the rule, the mechanics for people over and under 59½, and when the simpler options are better.

CPA Warning Label: Miss the 60-day rollover deadline and the 'trick' becomes a taxable distribution, possibly with a 10% penalty. You only get one IRA-to-IRA rollover per 12 months.

The even-withholding rule

For underpayment penalty purposes, estimated tax payments are credited on the date you make them. Withholding is different: income tax withheld is treated as paid in equal installments on each of the four due dates, unless you elect to treat it as paid on the dates it was actually withheld (IRS Publication 505).

So $8,000 withheld on December 10 counts as $2,000 paid on April 15, $2,000 on June 15, $2,000 on September 15, and $2,000 on January 15. If your required quarterly payment was $2,000, you are fully caught up, retroactively.

The penalty itself is calculated on Form 2210 based on how much you underpaid each quarter and for how long (IRS Topic 306). Withholding spread evenly fills each quarter's shortfall.

How the trick works

Over 59½: request a distribution from your traditional IRA in December and elect federal withholding high enough to cover your required payments. You can elect any percentage, up to 100%, on Form W-4R for nonperiodic distributions. The distribution itself is taxable income, so plan it as part of your bracket-filling for the year. If you were going to take IRA money or convert anyway, simply take it as a distribution with withholding instead of paying estimates.

Roth conversions: you can also have tax withheld from a conversion, but the withheld portion is a distribution that does not reach the Roth, and if you are under 59½, it may face the 10% additional tax.

Under 59½: see the rollover-and-replace method below.

Rollover-and-replace mechanics

Early retirees under 59½ can use a 60-day rollover to get the withholding benefit without permanently taking money out of the IRA:

1. Request a distribution of, say, $20,000 from a traditional IRA with $10,000 withheld for federal tax. You receive $10,000.
2. Within 60 days, deposit $20,000 into the same or another IRA: the $10,000 you received plus $10,000 from a taxable account to replace the withholding.
3. Because the full $20,000 was rolled over within 60 days, none of it is taxable or subject to the 10% additional tax (IRS Publication 590-B describes the rollover rules).
4. The $10,000 withheld is credited as tax paid, treated as paid evenly through the year.

Effectively, you moved $10,000 from your taxable account to the IRS through your IRA, and the IRS treats it as if you had paid on time all year.

Risks and the 60-day rule

• The 60-day deadline is strict. If you miss it, the distribution is taxable and, if you are under 59½, generally subject to the 10% additional tax. The IRS can waive the deadline in limited circumstances, but do not plan on it.
• One rollover per 12 months. You can make only one IRA-to-IRA 60-day rollover in any 12-month period, across all your IRAs. Direct trustee-to-trustee transfers and Roth conversions do not count toward this limit.
• You must replace the withholding. If you deposit only the $10,000 you received, the other $10,000 is a taxable distribution.
• RMDs cannot be rolled over. If you are taking a required distribution, that portion is not eligible for rollover.
• Custodian timing. Allow time for the distribution and redeposit to process; mailing a check on day 59 is a hobby, not a plan.

Example

Illustration. Assumptions: married couple, both 52, 2026. They expected little income and skipped estimates. In November they decide to do a $120,000 Roth conversion. Their 2025 tax was $3,000 and 2025 AGI was under $150,000, so the prior-year safe harbor is $3,000. Expected 2026 federal tax: about $10,000.

• Option 1: Pay nothing now, owe about $10,000 in April. Because they paid $0 toward the $3,000 safe harbor, they would owe a small underpayment penalty on $750 per quarter, calculated on Form 2210.
• Option 2: Make a $3,000 estimated payment on January 15, 2027. That covers the fourth quarter only; the first three quarters are still short.
• Option 3: In December, take a $6,000 IRA distribution with $3,000 withheld (50%), and roll the full $6,000 back within 60 days, using $3,000 from savings. The $3,000 is treated as $750 paid each quarter. No penalty. They owe the remaining $7,000 with the return.

Note that in this example the penalty avoided is modest, because the safe harbor was small. The trick matters more when the prior-year tax is large, as in the first year after retirement.

Second illustration: the first year after retiring

Illustration. Assumptions: single filer, 61, retired in January 2026. 2025 AGI was $190,000 and 2025 total tax was $36,000. 2026 income: $55,000 of IRA withdrawals and $20,000 of long-term gains. Estimated 2026 federal tax: roughly $6,000. No estimates paid by October.

• Prior-year safe harbor: 110% of $36,000 = $39,600 (2025 AGI exceeded $150,000). Unreachable and irrelevant, because the current-year test is smaller.
• Current-year safe harbor: 90% of $6,000 = $5,400, which works out to $1,350 per quarter.
• Because she is over 59½, she simply takes a December IRA distribution of $10,000 with $5,400 withheld. The withholding is treated as $1,350 paid each quarter: no penalty. The extra $10,000 of income was already part of her planned withdrawals for the year, so her income target stays the same if she trims a later distribution.

No rollover, no 60-day clock. For anyone over 59½, this is the easy version.

Simpler alternatives

• Regular withholding from Social Security with Form W-4V, at 7%, 10%, 12% or 22% of benefits.
• Pension withholding with Form W-4P.
• Annualized income method on Form 2210 Schedule AI, if your income really did arrive late in the year (see estimated taxes).
• Waiver request if you retired after reaching age 62 and the underpayment was due to reasonable cause, or for casualty or disaster.
• Just pay the penalty. It is essentially interest. For small underpayments it may be cheaper than the effort.

Electing actual withholding dates

The even-allocation rule is the default, but you may elect on Form 2210 to treat withholding as paid when it was actually withheld. That helps only in unusual cases, such as when most withholding happened early in the year and your income came late. Most retirees using the December strategy should leave the default alone.

Keep the custodian's distribution confirmation and the Form 1099-R, which reports both the gross distribution and the federal tax withheld (box 4). If you completed a rollover, the 1099-R will still show a distribution; you report the rollover on your return so it is not taxed.

When the trick is not worth it

If you are 59½ or older and planning an IRA distribution anyway, withholding is easy and free. If you are younger, the rollover method saves an interest-like penalty at the cost of complexity and a real risk of turning a paperwork fix into a taxable distribution. For a penalty of a few dollars, skip it. For a penalty of hundreds or thousands, it may be worth doing carefully.

Frugal Fran set up IRA withholding once and never thinks about estimates. Lavish Larry discovered the rule in December, then tried to use it twice in one year, which is how he learned about the one-rollover rule.

State withholding

Many states also treat withholding as paid evenly for their own underpayment penalties, and most IRA custodians let you elect state withholding at the same time. Check your state's rules; some require withholding if federal withholding is elected, and some do not allow it at all.
