If you have more than one traditional IRA, the IRS doesn't make you pull a separate required withdrawal out of each account. It adds up what you owe across all of them, then lets you take the total from whichever IRA you like. So you could empty one account and leave another untouched, and you'd still be fine — as long as the total dollars come out.
There's one big exception, and it's exactly the situation that trips people up. When you "annuitize" an IRA — turn it into a stream of monthly or yearly payments — that account stops playing by the pooling rules. From that point on, the annuity's payments cover its own required amount, and you can no longer use that account to help satisfy the requirement on your other IRAs.
That's the short version. The rest of this guide walks through what these terms mean, does the math with real numbers, and clears up the most common mistake people make when an annuity gets annuitized in the middle of the year.
First, what's an RMD?
RMD stands for Required Minimum Distribution. It's the minimum amount the IRS forces you to withdraw from most retirement accounts once you reach a certain age. The government gave you a tax break when the money went in, so eventually it wants its share. RMDs are how it collects.
For 2026, you generally have to start taking RMDs at age 73 if you were born between 1951 and 1959. If you were born in 1960 or later, your starting age becomes 75 (that change takes effect in 2033). Roth IRAs are different — they have no RMDs during your lifetime, so everything below is about traditional IRAs.
Skipping an RMD is expensive. The penalty for 2026 is a 25% excise tax on whatever you should have taken but didn't. That drops to 10% if you fix the mistake within a two-year correction window. Either way, you don't want to get this wrong.
The IRA aggregation rule
Here's the rule that makes traditional IRAs flexible. You calculate the RMD for each traditional IRA separately, using the account's December 31 balance from the prior year divided by a number from the IRS life-expectancy table. But once you have each account's figure, you add them together. You can then take that combined total from any one IRA, or split it however you want.
Say you have three traditional IRAs requiring $5,000, $3,000, and $2,000. That's $10,000 total. You could take all $10,000 from the first account and nothing from the other two. The IRS only cares that $10,000 left your traditional IRAs.
A quick warning: this pooling only works within the same type of account. Traditional IRAs aggregate with other traditional IRAs (and SEP and SIMPLE IRAs). But you can't use an IRA withdrawal to cover a 401(k)'s RMD, or vice versa. Each 401(k) stands alone. We're staying inside the traditional-IRA world here, so the pooling applies.
Here's what pools with what, at a glance:
| Aggregates together (can cover each other's RMD) | Stands alone (satisfies its own RMD only) |
|---|---|
| Traditional IRAs | Each 401(k) (employer plan) |
| SEP IRAs | Each 403(b) (employer plan) |
| SIMPLE IRAs | Annuitized IRA annuity |
What annuitizing changes
An annuity is a contract, often sold by an insurance company, that can pay you a guaranteed income. When you hold an annuity inside an IRA and it hasn't been "annuitized" yet, it's just another IRA asset with a balance, and it follows the normal aggregation rule above.
"Annuitizing" means flipping the switch. You convert that balance into a stream of payments — say, a set amount every year for life. Once you do that, the account no longer has a normal year-end balance to divide by a table number. Instead, the IRS treats the annuity payments themselves as that account's RMD.
This is the part people miss. After annuitizing, an annuity inside an IRA generally can no longer be combined with your other IRAs for RMD purposes. The IRS guidance here is technical, so I'll flag it plainly: the common reading is that an annuitized IRA annuity satisfies its own RMD through its payments and stops participating in the pool. The payments from the annuity count only toward that annuity — they don't help cover the requirement on your other accounts.
The math, step by step
Let's use a realistic version of the situation that prompts this question. You have two traditional IRAs:
- IRA A holds an annuity. Its RMD for the year is $8,000.
- IRA B holds regular investments. Its RMD for the year is $17,000.
Early in the year, before annuitizing anything, you took $10,000 out of IRA A. At that moment, IRA A was still a normal IRA, so under the aggregation rule that $10,000 counted toward your combined requirement.
Your combined RMD is $8,000 plus $17,000, which is $25,000. You'd already taken $10,000, leaving $15,000 to go. So far, so simple.
Now you annuitize IRA A mid-year, and it pays out $7,000 for the rest of the year. Here's where it gets subtle. Once IRA A is annuitized, its requirement is handled by its own payments. The question becomes whether IRA A's $8,000 obligation is now covered.
Add up what came out of IRA A this year: $10,000 taken before annuitizing, plus $7,000 in annuity payments after. That's $17,000 out of IRA A against an $8,000 requirement. IRA A is more than satisfied.
So what about IRA B? IRA B's own RMD is $17,000, and you haven't taken anything from IRA B yet. Because IRA A is now annuitized and standing on its own, you generally can't lean on IRA A's extra withdrawals to reduce IRA B. The cautious, widely-accepted answer is that you still need to take the full $17,000 from IRA B.
Here's the whole year on one screen:
| IRA A (holds the annuity) | IRA B (investments) | |
|---|---|---|
| RMD required | $8,000 | $17,000 |
| Taken before annuitization | $10,000 | $0 |
| Annuity payments after | $7,000 | $0 |
| Total withdrawn | $17,000 | $0 |
| RMD satisfied? | Yes | No — still owes $17,000 |
This is where the original poster's math went wrong. They subtracted the $10,000 they'd already pulled from IRA A from IRA B's $17,000 and concluded they only needed $8,000 more from IRA B. That subtraction would work if both accounts were still ordinary IRAs in the pool. But annuitizing IRA A breaks the pool. The $10,000 helped satisfy IRA A (which is now self-contained), not IRA B.
I'll be honest that this is exactly the kind of edge case where the timing of the annuitization and the specific contract terms matter, and the IRS rules are genuinely murky. If real dollars and penalties are on the line, this is worth confirming with the annuity provider and a tax preparer before year-end.
"But I already took out more than I needed"
A natural reaction is: "I pulled $17,000 out of IRA A and only owed $8,000 there — can't the extra $9,000 count somewhere else?" Unfortunately, no. There's no carryover from one account to another once the pooling stops, and there's no carryover from one year to the next either. Taking more than your RMD in a given year is allowed, but the excess doesn't bank credit against future requirements or other accounts.
The flip side: those extra withdrawals are still fully taxable as ordinary income for 2026. Pulling out far more than required from a traditional IRA can quietly push you into a higher bracket. For 2026, a single filer crosses from the 22% bracket into the 24% bracket at $105,700 of taxable income. Large, unplanned withdrawals can nudge you over lines like that, so it pays to know your number before you withdraw, not after.
Common mistakes to avoid
A few traps catch people repeatedly in multi-account situations:
- Assuming all account types pool together. Traditional IRAs aggregate with each other, but 401(k)s and other employer plans each compute and satisfy their own RMD separately.
- Forgetting that annuitizing breaks the pool. Once an IRA annuity is annuitized, treat it as its own island. Its payments cover its own requirement and nothing else.
- Double-counting early withdrawals. Money you took from an account before annuitizing it counts toward that account, not toward the IRAs still in the pool.
- Ignoring the tax bracket impact. Required or not, every traditional-IRA dollar is taxable income for 2026, and lumpy withdrawals can spike your rate.
One bright spot worth knowing: if you're 70½ or older, a Qualified Charitable Distribution (QCD) lets you send IRA money straight to charity. For 2026 you can give up to $111,000 this way per person. It counts toward your RMD and stays out of your taxable income. That's a rare way to satisfy a requirement without raising your tax bill.
Pulling it together
When you have several traditional IRAs, think of them as one pool: add up each account's RMD, then take the total from wherever's convenient. The moment you annuitize one of those IRAs, pull it out of the pool. Its payments handle its own requirement, and your other IRAs must still cover their full amounts on their own.
Because these withdrawals are taxable and can shift your bracket, it's smart to map out your retirement income before you start pulling money — and to think about whether moving some traditional-IRA money to a Roth over time could shrink future RMDs altogether. A [Roth conversion calculator](/calculators/roth-conversion) can show how converting now might lower the required withdrawals (and the tax bills) you'll face in later years. Running the numbers ahead of time beats discovering a surprise tax bracket or a missed-RMD penalty after the fact.
