Required Minimum Distribution

Definition

A required minimum distribution is the minimum amount that must be distributed annually from certain tax-qualified retirement accounts and tax-deferred arrangements once the account owner reaches the age specified by current law, calculated under formulas set by the Internal Revenue Code.

Why it matters

Required minimum distributions are the mechanism by which the federal tax code treats accumulated tax deferral as a finite arrangement rather than an indefinite one — at a statutory age, the deferral period ends and distributions must begin at a calculated minimum pace. The structural consequence is that tax-qualified accounts and qualified annuities cannot serve as indefinite deferral vehicles; they have a forced distribution schedule whose pace increases with age. The rules apply differently to non-qualified annuities (where contract-level RMDs generally do not apply) and to inherited accounts (where rules changed materially under the SECURE Act of 2019, addressed separately in the stretch provisions entry).

How it works

For the account owner, RMDs are calculated each year by dividing the prior-year-end account balance by a distribution period from IRS-published life expectancy tables; the required beginning date is age-based and has shifted upward — most recently to age 73 for individuals reaching that age in or after 2023, with a further shift to age 75 for individuals born in 1960 or later. RMD calculation and timing rules vary by account type (traditional IRA, Roth IRA — exempt during the owner's lifetime — 401(k), 403(b), 457(b)). For an annuity inside a qualified account, the annuitized payment stream may satisfy the RMD requirement for that contract, with specific rules governing how the contract's value is reported for aggregation across multiple accounts. Failure to take a required RMD triggers an excise tax on the under-distributed amount.

In practice

A contract owner approaching the required beginning date for a qualified annuity should confirm with the account custodian how RMDs will be calculated for the annuity — whether the contract's actuarial value is used, whether annuitized payments satisfy the requirement directly, and how the contract's RMD interacts with RMDs from other qualified accounts the owner holds. Aggregation rules differ by account type: like-type accounts (multiple IRAs) may permit aggregation of total RMD across the group; unlike-type accounts (IRA and 401(k)) generally do not. For a non-qualified annuity, contract-level RMDs generally do not apply, but the contract owner should verify whether ownership structure (trust, non-individual) changes the analysis. A contract owner inheriting a qualified annuity should consult the post-SECURE Act inherited-account rules, which materially compressed the distribution period for most non-spouse beneficiaries.

In the Longevity Standard Framework

Required minimum distributions are a tax-mechanical feature of certain qualified annuity arrangements rather than a component of the cost-of-income framework. The framework's structural comparison — with the frictionless pool as the benchmark and solo drawdown as the baseline — operates on a pre-tax economic footing, and the timing and pace of forced distributions sit outside that structural layer. RMD rules can interact with the framework's findings indirectly by constraining the timing of cash flows from qualified contracts, but the framework's evaluation of arrangements on a cost-of-income basis is conducted independently of distribution-timing constraints. After-tax outcomes are an additional layer applied to the framework's findings rather than a determinant of them.
