The Sept. 15 Estimated-Tax Deadline Just Passed. Retirees Who Took a Big IRA Withdrawal This Summer Still Have One Way to Avoid the Penalty in April
Missing the September 15 estimated-tax deadline left many retirees staring at a growing underpayment penalty, but a little-known IRS rule about how withholding gets credited could still wipe out the damage before the year ends.

The third-quarter estimated tax deadline of September 15 has passed. For a retiree who withdrew a five-figure IRA distribution over the summer and either declined withholding or accepted the default that rarely covers the actual liability, the tax bill is now exposed. The estimated payment that should have covered it did not arrive by that date. One clean way out remains before December 31.
Why a Missed Quarter Costs More Than People Assume
The underpayment penalty accrues quarter by quarter from each missed deadline until you pay the shortfall. The IRS sets the rate and adjusts it quarterly, pegged to the federal short-term rate plus three percentage points. That short-term rate sits near the Fed’s policy stance, with the federal funds target upper bound currently 3.75%, unchanged since the start of the year. A single large mid-summer IRA withdrawal creates a Q3 shortfall the IRS treats as a Q3 shortfall, even if the full balance is settled in April.
A Withholding Rescue Most Retirees Have Never Heard Of
Federal tax withheld from wages, pensions, Social Security, and retirement distributions is treated as paid evenly across the four installment periods, regardless of when it was actually withheld. Estimated payments are credited only on the date they are made. That asymmetry creates the planning opportunity.
A retiree can take another distribution before year-end and direct a substantial portion to federal withholding. Because that withholding is deemed paid evenly across the year, it can be applied against the underpaid Q1, Q2, and Q3 installments, curing or sharply reducing the accrued penalty. You make the election when the distribution is processed, and you generally can’t apply it retroactively.
It must be a new distribution, arranged with the custodian, with the withholding percentage specified on the request. Some custodians allow up to 100% federal withholding on IRA distributions; many require a signed form.
Safe Harbors Worth Aiming At
A taxpayer avoids the underpayment penalty by paying, through withholding and timely estimates combined, at least 90% of the current year’s tax liability or 100% of the prior year’s liability. For taxpayers whose prior-year adjusted gross income exceeded $150,000 ($75,000 if married filing separately), the prior-year threshold rises to 110%. The prior-year target is usually easier to hit because the number is already on last year’s return and requires no estimate of an unfinished year.
What the January Payment Can and Cannot Do
The fourth-quarter estimated tax payment is due January 15 of the following year. Sending a large check on that date stops the penalty clock going forward but does not retroactively cure the earlier quarters. A January estimated payment credits as of January. Withholding on a December distribution credits as if paid evenly from the first quarter onward. For a retiree already behind on Q1, Q2, and Q3, only the withholding route reaches back.
Annualized Income, Waivers, and State Rules
A retiree whose income arrived unevenly can use the annualized income installment method on Form 2210, which recalculates the required installment for each quarter based on income actually received through that point. It is rarely worth it when the withholding fix is available. A penalty waiver may apply in cases of casualty, disaster, or other unusual circumstances, and specifically for taxpayers who retired after reaching age 62 or became disabled during the tax year, provided the underpayment was due to reasonable cause.
States run their own estimated tax calendars, thresholds, and safe harbors, and a federal fix does nothing for a state shortfall. This quarterly-credit quirk is one of nine IRS rules that quietly drain retirement accounts, all mapped in a free tax trap guide here.
How to Prevent a Repeat
A retiree who expects to take large distributions in future years can skip the quarterly calendar by building withholding into the distributions themselves and into Social Security payments. For the current year, the action is narrower: contact the IRA custodian, request a distribution before December 31, and direct enough to federal withholding to hit the 100% or 110% prior-year safe harbor. That single step can convert an accruing penalty into a clean April return.
