Can You Combine RMDs From Multiple Traditional IRAs Into One Withdrawal?
Anyone holding more than one traditional IRA eventually runs into a practical question once required withdrawals begin: does each account need its own separate withdrawal, or can they be handled together?
The short answer
Yes, generally. Traditional IRA owners can calculate the required minimum distribution for each traditional IRA separately, add those amounts together, and then withdraw the total from just one of the IRAs, or split it across several, as long as the combined total is satisfied. This is often called the aggregation rule, and it applies specifically to IRAs owned by the same person.
How the calculation actually works
Each traditional IRA has its own year-end balance, and the required withdrawal amount is calculated separately for every account based on that balance and the applicable life expectancy factor. Once each individual amount is known, the account owner can add them together to get one combined figure. That combined figure is the total that must come out across all the traditional IRAs by the deadline, regardless of which specific account the money is pulled from. Nothing requires the withdrawal to be split proportionally or to come from the account it was calculated on.
Why aggregation exists
- It reduces administrative friction. Without aggregation, someone with several small IRAs would need to remember and process a separate withdrawal for every single account every year.
- It allows flexibility in timing and source. An account owner might prefer to draw from the IRA with the most cash on hand, or the one holding investments they’d like to trim, rather than pulling proportionally from each.
- It still requires accurate math. Aggregation doesn’t reduce the total amount owed — it only changes how many separate transactions are needed to satisfy it.
Where aggregation does not apply
This flexibility is generally limited to accounts of the same type. Traditional IRAs can be aggregated with other traditional IRAs, but an amount owed from a 401(k) or similar workplace plan typically cannot be satisfied by withdrawing extra from an IRA, and vice versa — each plan type generally needs its own withdrawal. Inherited IRAs are usually treated separately from an owner’s own IRAs as well, and aggregation rules for inherited accounts can differ depending on the relationship to the original owner and other factors, so they’re worth treating as their own category rather than assuming they blend in with personal accounts.
What documentation tends to matter
Because the total obligation is based on the sum of several account balances, keeping track of each IRA’s year-end value and the resulting individual calculation is useful even after the withdrawals are combined. If a discrepancy or missed amount ever comes up, having a record of how each account’s portion was calculated makes it easier to show the combined total was actually satisfied, rather than relying on memory or an assumption that “close enough” covered it.
What to weigh
Combining withdrawals can simplify recordkeeping and give more control over which investments are sold to generate cash, but it also means one account absorbs a bigger tax-reporting event for the year if all the money is pulled from a single IRA. Because rules around retirement account withdrawals are set by the government and have changed over time, it’s worth confirming current requirements before assuming last year’s approach still applies exactly the same way this year.
The takeaway
Aggregating required withdrawals across traditional IRAs is a matter of convenience, not a way to reduce what’s owed. The total obligation is fixed by each account’s balance and the applicable calculation; aggregation only changes how many separate withdrawals it takes to satisfy that total, and the option generally doesn’t extend across different types of retirement accounts.
