RMD by age

RMD at age 105: 21.74% of your balance

At 105, your required minimum distribution (RMD) is last December 31’s balance divided by 4.6, the IRS Uniform Lifetime Table factor — that’s 21.74% of the account, or $21,739 for every $100,000. In 2026 that means people born in 1921; in 2027, people born in 1922.

Where 105 sits: the share you must take, ages 73–105

Who turns 105 in 2026 and 2027?

People born in 1921 turn 105 in 2026, and people born in 1922 in 2027. Neither group reaches its RMD age now: the 2026 group has been taking RMDs since 1991 or 1992, the 2027 group since 1992 or 1993. Both use the same factor at 105: 4.6.

One exception to the dates above: if you kept working past your RMD age, own 5% or less of the company and its plan let you delay, that plan’s first RMD is for the year you retire — due by April 1 of the next year. IRAs never get this delay.

Born in 1921? The old rules split your year at July 1: with a January–June birthday your RMD age was 70½ and your first RMD year 1991; with a July–December birthday, 70½ and 1992. Either way, the factor you use today is the same: 4.6 at 105.

The table always uses the age you reach on your birthday during the year, so someone born on December 31, 1921 uses 105 for all of 2026. See the full RMD table for every age from 72 to 120 and older.

Work out your own RMD at 105

The calculator starts with a 1921 birth date and a $500,000 balance. Change either one, pick 2027 to plan ahead, or add a much younger spouse.

How do you calculate your RMD at 105?

Take each account’s balance on December 31 of last year and divide it by 4.6, the IRS factor for 105. On a $500,000 IRA that’s $108,696 for the year — about $9,058 a month if you’d rather spread it out. You can take more, but never less, and the extra doesn’t count toward next year.

Find last year’s December 31 balance for every traditional, SEP and SIMPLE IRA, 401(k), 403(b) and 457(b). Leave out Roth IRAs and Roth 401(k) and 403(b) money — they have no RMDs while you’re alive.
Use the age you reach on your birthday this year — 105 if you were born in 1921 — even if that birthday is on December 31.
Divide by 4.6, the Uniform Lifetime Table factor for 105 (or by the Joint and Last Survivor factor if your spouse qualifies — see below).
Withdraw it by the deadline: December 31, or April 1 of next year for a first RMD. You can add up your IRA RMDs and take the total from any one IRA; each 401(k) has to pay its own.

One number worth knowing: after an RMD of 21.74%, your investments have to earn about 27.8% this year just for the account to end the year where it started. Earn more and next year’s RMD grows; earn less and the account slowly shrinks — exactly what the rules intend.

Do RMDs ever stop?

No. The IRS table runs to age 120 and older, where the factor is 2.0 — 50% of the balance every year. At 105 you must take 21.74%, or $21,739 per $100,000, however small the account. The table never asks for more than half the balance, so the RMD alone never empties it.

Missing one is expensive: an excise tax of 25% of the shortfall, cut to 10% if you fix it in time. The IRS can waive it entirely for a reasonable error you correct promptly; you ask by attaching an explanation to Form 5329. If someone else handles your accounts, ask the custodian to pay the RMD automatically each year.

What happens to the RMD in the year you die?

It still has to come out. If you die after your RMDs have started, whatever part of that year’s RMD you hadn’t taken must be withdrawn by your beneficiaries by December 31. After that they follow the inherited-IRA rules — for most non-spouse heirs, yearly RMDs and a 10-year deadline.

If the death comes late in the year, there’s relief: the IRS waives the excise tax automatically when the heirs take the missing amount by the end of the following year, or by their tax-filing deadline (with extensions) if that is later. Heirs use a different table, the Single Life Table, and the rules depend on who they are. The inherited IRA calculator works it out; the beneficiary table summary shows the factors.

What if your spouse is 15 years younger?

If your spouse is your only beneficiary all year, you use the Joint and Last Survivor Table instead. At 105 with a 90-year-old spouse the factor is 6.1 rather than 4.6, so you must take 16.39% of the balance instead of 21.74%.

Worked example: RMD at 105 with a spouse 15 years younger
Balance on December 31, 2025	$500,000
Ages reached in 2026	You 105 (born 1921), spouse 90 (born 1936)
Joint and Last Survivor factor	6.1 (row 105, column 90)
RMD with the joint table	$500,000 ÷ 6.1 = $81,967
RMD with the Uniform table	$500,000 ÷ 4.6 = $108,696
You withdraw less	$26,728 (24.6% less)

Two conditions, both strict: your spouse must be more than 10 years younger and the sole beneficiary of that account for the entire year. Marital status is fixed on January 1, so a divorce or a death during the year changes the table only from the next year. At a gap of exactly 10 years the two tables give the same factor. Try your own ages in the RMD calculator with a younger spouse or the joint-table lookup.

Can a qualified charitable distribution cover your RMD at 105?

Yes. Past age 70½, money sent straight from your IRA to a charity — a qualified charitable distribution (QCD) — counts toward your RMD and never shows up in your taxable income, up to $111,000 per person in 2026. It can cover part of the RMD or all of it.

At 105, that limit covers the entire RMD on any IRA balance up to $510,600. A QCD beats taking the RMD and then writing a check: the gift never enters your adjusted gross income, which can keep more of your Social Security untaxed and your Medicare premiums lower — even if you take the standard deduction.

The money must go directly from the IRA to the charity by December 31. It can’t come from a 401(k) — to give from 401(k) money, take that plan’s RMD for the year first (an RMD can’t be rolled over), then roll the rest into an IRA — or from an ongoing SEP or SIMPLE IRA. The IRS has not announced the 2027 limit yet. Not announced yet

Gift on your mind but not sure how much? On $500,000 the whole $108,696 RMD could go to charity; next year at 106 the same balance would require $116,279.

RMD at 105: common questions

How much is the required minimum distribution at age 105?

At 105 you divide last December 31’s account balance by 4.6, the IRS Uniform Lifetime Table factor, which means withdrawing 21.74% of it. That is $21,739 per $100,000, $108,696 on $500,000 and $217,391 on $1 million. If your only beneficiary is a spouse more than 10 years younger, the Joint and Last Survivor Table gives a smaller RMD.

What birth year is age 105 for RMDs in 2026?

Anyone born in 1921 reaches 105 on their 2026 birthday, and the IRS uses that age for the whole year — even if the birthday is in December. In 2027, the age-105 group is people born in 1922. People born in 1921 have been taking RMDs since 1991 or 1992, depending on their birth date.

Is there still an RMD at age 105?

Yes. RMDs never stop while you own a traditional IRA or 401(k). At 105 the factor is 4.6, so you must withdraw 21.74% of the prior year-end balance — $21,739 per $100,000. The percentage keeps rising but never reaches 100%: at 120 and older the factor is 2.0, or 50% of the balance a year.

What happens if I miss my RMD at 105?

The IRS charges an excise tax of 25% of the amount you didn’t take — $27,174 if you skipped the whole $108,696 RMD on $500,000. Take the missed amount and report it on Form 5329 by the end of the second year after the year it was due — before the IRS contacts you — and the tax drops to 10%, or $10,870. For a reasonable error you fix promptly, you can ask the IRS to waive it entirely.

Can a charitable donation count as my RMD at 105?

Yes. You are past 70½, so a qualified charitable distribution (QCD) sent directly from your IRA to a charity counts toward the RMD and stays out of your taxable income — up to $111,000 per person in 2026. At 105, a $108,696 QCD would cover the whole RMD on a $500,000 IRA. The IRS has not announced the 2027 limit yet.
