Methodology & sources

The controls require confirmed facts; they do not certify a beneficiary designation, trust, medical condition or election. Unsupported cases and invalid inputs produce no legal verdict or schedule.

Supported categories and exclusions

Under §1.401(a)(9)-4, EDB categories include a surviving spouse, the owner's child under 21 at death, a qualifying disabled or chronically ill individual, and an individual not more than ten years younger. Eligibility is tested at death. Life-expectancy availability depends on account terms and applicable elections.

This calculator models only a direct, separately treated non-spouse interest with the supplied category confirmed, or a confirmed estate/charity interest. It does not determine whether multiple beneficiaries qualify for separate treatment. Unresolved shared interests and all trusts are deferred; see-through status cannot be inferred from a trust's label.

Pre-2020 inheritances may depend on existing elections, the 2020 waiver and the 2022 table transition. No historical reconstruction is attempted. Spouse elections require additional facts; no automatic “No annual RMD” result is supplied for a spouse.

For the owner's minor child using life expectancy, the final deadline is December 31 of the tenth year after the year of turning 21, while annual payments continue. Age 21 comes from final §1.401(a)(9)-4(e)(3). A separate disability/chronic-illness category can affect treatment. This tool does not calculate child or former-child deadlines.

For IRAs, §1.408-8(b)(4) removes specified regulatory delivery requirements for trust and disability/chronic-illness documents. It does not eliminate substantive eligibility, certification requirements or custodian procedures.

Roth owner RMDs and beneficiary deadlines

IRC §408A(c)(4) exempts original Roth IRA owners from lifetime RMDs. Under §1.408-8(b)(1)(ii), a Roth IRA owner is treated as dying before the required beginning date. A supported direct ordinary non-EDB therefore has no annual RMDs in years 1–9 and must complete payout by December 31 of year ten after the owner's death. A confirmed non-designated beneficiary generally has a five-year payout period.

This is not a universal rule that inherited Roth accounts never require annual payments. Life-expectancy EDB, former-minor-child and successor rules can require continuing annual payments. Those exceptions must not be replaced with a new ordinary ten-year window.

For context, the first cohort subject to RMD age 75 was born in 1960 and reaches 75 in 2035; an IRA owner's corresponding first RBD is generally April 1, 2036. The fetched final §1.401(a)(9)-2 specifies age 73 for 1951–1958 births and leaves the 1959 provision reserved; the accompanying proposed rule specifies 73 for 1959. This calculator does not determine an owner's or spouse's RMD start age.

Five-tax-year qualification and schedule formulas

The inherited Roth IRA qualification period starts with the owner's first applicable Roth IRA contribution tax year and does not restart at death. For example, a 2022 first year completes five tax years at the end of 2026, so beneficiary distributions qualify beginning January 1, 2027. Roth ordering rules generally distribute regular contributions, then conversions in order, then earnings. Nonqualified earnings may be taxable; the beneficiary death exception removes the federal early-distribution tax.

Deferred: B × (1 + r)N, paid in the final year. Equal annual: B divided by the present value of N unit end-of-year withdrawals, equivalent to B × r × (1+r)N / ((1+r)N − 1); at zero return, B/N. N is the complete initial ten- or five-year window, not a guessed remaining term.

Non-spouse life expectancy: preceding December 31 balance divided by the Single Life factor for age attained in the first distribution year, then the original factor minus one per later year, with a floor of one. The table effective in 2022 is used for these current/upcoming first years. Growth is applied after the annual RMD for this illustration, unlike the end-year withdrawal convention in the other patterns. Historical factors and spouse recalculation are not modeled.
