IRA Withdrawal After Age 80: RMDs, Taxes, and QCDs

An IRA withdrawal after age 80 is not optional. Every year, you must pull a required minimum distribution (RMD) from each Traditional, SEP, or SIMPLE IRA you own, report it as ordinary income, and get it done by December 31. Miss it and the IRS charges an excise tax on the shortfall. Get it right and there are still several ways the withdrawal can quietly raise your Social Security tax bill and your Medicare premiums two years down the line.

Here is what an 80-year-old actually needs to know to handle the withdrawal, keep the tax bill manageable, and avoid the penalty traps.

Calculating Your Required Withdrawal at 80

The formula is simple. Take the total balance of your Traditional, SEP, and SIMPLE IRAs as of December 31 of the prior year, then divide by the distribution period factor the IRS assigns to your age in the Uniform Lifetime Table (Table III) of Publication 590-B.¹

The factors shrink each year, so the required percentage grows:

Age 80: 20.2
Age 82: 18.5
Age 85: 16.0
Age 88: 13.7
Age 90: 12.2

An 80-year-old with $500,000 across all Traditional IRAs on December 31, 2025, divides by 20.2 and must withdraw about $24,752 in 2026. That same $500,000 balance at 85 produces an RMD of $31,250.¹

The Much-Younger Spouse Exception

If your spouse is your sole IRA beneficiary and is more than 10 years younger than you, use the Joint and Last Survivor Life Expectancy Table (Table II) instead. The divisor is larger, the required withdrawal is smaller, and the tax bill drops accordingly.¹ Confirm with your custodian that your spouse is on file as sole beneficiary, because the default calculation uses the less favorable Uniform Lifetime Table.

If You Own Several IRAs

Calculate an RMD for each IRA separately, then add them up. You can pull the full combined amount from just one account, split it across several, or take it however you like. The same flexibility does not extend to employer plans. A 401(k) RMD must come out of that 401(k), and 403(b) accounts can only be aggregated with other 403(b) accounts.²

What Does Not Apply to You

Two things retirees often ask about are worth ruling out quickly. Roth IRA owners never face RMDs during their own lifetime, so if some of your retirement money sits in a Roth, leave it there. And the still-working exception that lets some people delay RMDs applies only to employer plans, not IRAs. Even if you have a paycheck at 80, your Traditional IRA distributions are due each December 31.³

How the Withdrawal Is Taxed

Every dollar from a pre-tax IRA is ordinary income on your federal return. It stacks on top of pensions, Social Security, interest, and everything else, and it gets taxed at your marginal rate.⁴ For 2026, the brackets most retirees land in are 12% (over $12,400 single / $24,800 joint), 22% (over $50,400 / $100,800), and 24% (over $105,700 / $211,400). Taxpayers 65 and older get an additional standard deduction of $2,050 (single) or $1,650 per spouse (joint) on top of the regular amount.⁵

State income tax varies widely. Some states impose none, some exempt retirement income partly or entirely, and some treat IRA withdrawals like wages. Two retirees with identical federal returns can owe very different totals depending on where they live.

The Two Costs People Don’t See Coming

An IRA withdrawal can make other income more expensive. Social Security benefits become partly taxable when your provisional income (adjusted gross income plus tax-exempt interest plus half your Social Security) crosses $25,000 single or $32,000 joint, with up to 85% of benefits taxable above $34,000 or $44,000.⁶ Those thresholds have never been indexed for inflation, so most retirees with meaningful IRA balances are already at 85%.

Medicare Part B and Part D premiums add an Income-Related Monthly Adjustment Amount (IRMAA) for higher-income beneficiaries, and it works on a two-year lag. Your 2026 income determines your 2028 premium. For 2026, IRMAA starts at MAGI above $109,000 single or $218,000 joint, with progressively higher surcharges up to the top tier at $500,000 single or $750,000 joint.⁷ A withdrawal that pushes you just over one of those cliffs can cost hundreds of dollars a month in premiums two years later.

Cutting the Tax with a Qualified Charitable Distribution

If you give to charity, the Qualified Charitable Distribution (QCD) is the most efficient tool available to you. You direct the IRA custodian to send funds straight to a qualifying charity. The transfer counts toward your RMD, but it never appears in your taxable income at all.⁸

For 2026, the annual QCD limit is $111,000 per person, indexed for inflation. Married couples with separate IRAs can each transfer up to $111,000.

Three rules decide whether the transfer works:

The money must go directly from custodian to charity. If it lands in your bank account first, it becomes a taxable distribution followed by a separate donation, which is a far worse result.
The recipient must be a 501(c)(3). Private foundations, donor-advised funds, and supporting organizations don’t qualify.⁸
The transfer must complete by December 31 to count for that year’s RMD.

Because a QCD keeps the money out of your adjusted gross income entirely, it can hold you below the Social Security taxation thresholds, keep you under an IRMAA cliff, and preserve other income-sensitive benefits. For retirees who would give anyway, routing the gift through the IRA is almost always the better path.

Getting the Withholding Right

The default federal withholding on an IRA distribution is 10%.⁹ For someone in the 22% or 24% bracket, that leaves a gap large enough to produce a nasty balance due at filing time, plus an underpayment penalty.

Two ways to close the gap. You can file Form W-4R with your custodian and set the rate anywhere from 0% to 100%; the election stays in place for future distributions from that account until you change it.⁹ Or you can make quarterly estimated tax payments. The underpayment penalty is generally avoided if you pay at least 90% of the current year’s tax or 100% of the prior year’s, whichever is less. If your prior-year AGI exceeded $150,000 ($75,000 married filing separately), the safe harbor rises to 110% of last year’s tax.¹⁰

One useful quirk: federal tax withheld from an IRA distribution is treated as paid evenly across the year, no matter when the money actually came out. Taking the full RMD late in the year with high withholding can cover quarters you missed.

What Happens If You Miss the Deadline

If you don’t withdraw the full RMD by December 31, the IRS charges a 25% excise tax on the shortfall.¹¹ Before 2023 it was 50%, so the current rate is already a meaningful reduction under the SECURE 2.0 Act.

Fix the mistake within the correction window and the penalty drops to 10%. That window runs from when the penalty is triggered until the earliest of an IRS deficiency notice, an IRS assessment, or the last day of the second tax year after the year of the missed distribution.¹¹ For most taxpayers that means about two years to take the missed amount, file a corrected return, and settle at the 10% rate.

You report the shortfall on Form 5329. If you had a legitimate reason for missing it, attach a written explanation and request a waiver of the penalty entirely.¹² The IRS does grant these, especially when the missed amount has already been taken and the error was not willful. Serious illness, incapacity or death of a family member handling your finances, and inability to access records are all recognized grounds.¹³

What Your Beneficiaries Will Face

At 80, planning the withdrawal and planning the inheritance are the same conversation. For most non-spouse beneficiaries who inherit after 2019, the entire inherited IRA must be emptied within 10 years of your death, with no option to stretch distributions over the beneficiary’s own lifetime.³ Because you have already passed your required beginning date, non-spouse beneficiaries also generally have to take annual RMDs during that 10-year window rather than waiting to drain the account at the end.

A narrower group qualifies as an “eligible designated beneficiary” and can still stretch withdrawals over their own life expectancy:

A surviving spouse, who can also roll the account into their own IRA and delay RMDs until age 73.
Minor children of the account owner, though the 10-year clock starts when the child reaches the age of majority.
Disabled or chronically ill individuals.
Beneficiaries who are no more than 10 years younger than you.

These categories come from the eligible designated beneficiary definition in the tax code.¹⁴ Adult children, the most common case, don’t fit any of them, so they fall under the 10-year rule. A large Traditional IRA left to your kids can produce a compressed, expensive tax event on their returns. If lowering that burden matters, partial Roth conversions during your lifetime or naming a charity as beneficiary for part of the balance are worth raising with a tax advisor.
