Retroactive Annuity Starting Date Regulations: Election and Makeup Pay

A retroactive annuity starting date is a provision some defined benefit pension plans offer that lets a participant elect an annuity start date earlier than the date the plan actually delivered the required written benefit explanation. When the election is valid, the plan pays a lump-sum makeup covering the missed payments plus interest, and future payments continue as if the annuity had started on that earlier date. Federal authority for the mechanism sits in Treasury Regulation Section 1.417(e)-1(b)(3)(iv), and it applies only to defined benefit plans, not to 401(k)s or other defined contribution arrangements.¹

What the Election Actually Does

The annuity starting date is the first day of the first period for which a pension payment becomes due. That date fixes the numbers that follow: the applicable mortality table, the applicable interest rates under Section 417(e), and the form of the annuity. A retroactive annuity starting date, or RASD, is an ASD the participant affirmatively elects that falls on or before the date the plan delivered the required qualified joint and survivor annuity (QJSA) explanation. In plain terms, the participant is telling the plan: my benefit should have started on this earlier date.¹

Two boundaries matter before you go further. Offering an RASD is optional for the plan. The regulation says a defined benefit plan “is permitted to provide” retroactive starting dates and “is not required to.” A plan that offers the feature is free to add conditions of its own, such as excluding participants who take a lump sum. And the mechanism is unavailable to defined contribution plans; if you are in a 401(k) or similar plan, this is not the tool for your situation.¹

When a Retroactive Start Date Comes Into Play

The most common trigger is a late QJSA explanation. The plan is required to deliver the written explanation of the QJSA and other payment forms no fewer than 30 days and no more than 90 days before the annuity starting date.² When the notice arrives late but the participant’s entitlement to begin benefits started earlier, the RASD regulation exists to close that gap.

Missing spousal consent is a related trigger. If the participant elected a form of payment other than the QJSA, the spouse must consent in writing, witnessed by a plan representative or notary.³ Without proper consent, the original election was defective. The plan must go back, secure the consent, and the participant may then elect an RASD tied to the date benefits should have started.

Administrative delay is another common story. A participant who separated, met the plan’s requirements for an immediate benefit on a specific date, and then waited months for the first check because of a processing backlog is squarely in RASD territory. The entitlement existed on the earlier date; the plan simply did not act on it.

Calculation errors round out the list. Wrong segment rates, an outdated mortality table, a missed early retirement subsidy: each one produces an underpayment that a corrected ASD and a makeup distribution can fix. The common thread across every scenario is that the participant received less, or received it later, than they were entitled to. Overpayments follow a different path.

Conditions the Election Must Meet

Several conditions govern whether a retroactive election is valid. The retroactive date cannot precede the earliest date the participant could have started benefits under the plan’s terms as of that date. If the plan would not have permitted payments to begin until age 55, the RASD cannot reach back before the participant turned 55.¹

The spousal consent question shifts for an RASD. Rather than looking to the spouse as of the original date, the regulation looks to the participant’s spouse at the time distributions actually commence. That spouse must consent to the retroactive election. This matters when the participant has remarried between the retroactive date and the actual payment date.

Two constraints on the benefit itself cannot be waived:

The benefit as of the retroactive date must satisfy Section 417(e)(3), using the applicable segment rates and mortality table in effect on that retroactive date rather than the date the plan finally starts paying.
The corrected benefit must fall within the Section 415 annual benefit limit as applied to the retroactive date. For 2026, that limit is $290,000.⁴

The plan is expected to document the whole correction: how the error was discovered, the participant’s affirmative election, the spousal consent, the recalculation methodology, and the resulting makeup payment. That file is the plan’s protection if the IRS later examines the correction.

What the Makeup Payment Includes

The makeup has two components. First, the sum of every periodic payment that should have been made between the retroactive date and the date the plan actually delivers the correction. Second, interest on each of those missed payments, accruing separately from the date each payment would have been due through the date the plan actually pays the makeup. The regulation calls for an “appropriate adjustment for interest” without prescribing a specific rate; the plan document typically fixes the rate, or the plan uses a commercially reasonable benchmark.¹

Recalculation runs off the correct benefit formula, the segment rates in effect on the retroactive date, and the applicable mortality table. If the participant received some payments before the correction (perhaps at the wrong amount), those get credited against the gross amount owed. What remains, plus accumulated interest, is the makeup.

Once the makeup is paid, ongoing payments reset. Future checks reflect the corrected benefit as if the annuity had been running from the retroactive date all along. If the correction also changes the form of annuity, for example from a single-life annuity to a joint-and-survivor annuity, the base amount changes and the plan re-runs the entire calculation.

How the Makeup Payment Is Taxed

The makeup payment is taxable in the year received, even though it covers earlier years. Missed principal and accrued interest are both included in income for that single tax year, which can push the participant into a higher bracket. The plan reports the distribution on IRS Form 1099-R, with the Box 7 code chosen to reflect the corrective character of the payment.⁵

If you do not elect a direct rollover to an IRA or another qualified plan, the plan must withhold federal income tax at a flat 20% on the eligible rollover portion.⁶ A direct rollover into an eligible retirement plan avoids that withholding. Before making the distribution, the plan must deliver the Section 402(f) notice explaining rollover options and withholding, no fewer than 30 days and no more than 90 days before the distribution; a participant who has received the notice can affirmatively elect an earlier distribution.⁷

If you take the check and want to roll it over yourself, you have 60 days from receipt to deposit the eligible amount into an IRA or qualified plan. Miss that window and the full distribution is currently taxable, and the 10% early distribution penalty may apply if you are under 59½.⁸ State withholding may also apply, depending on where you live.

Required Minimum Distributions and the Retroactive Date

If the retroactive date sits on or after the date your required minimum distributions should have begun, the makeup has to be structured to cover those prior-year RMDs. A qualified plan must begin distributing a participant’s entire interest no later than the required beginning date, either as a lump sum or in periodic payments over the participant’s life or life expectancy.⁹

Any portion of the makeup that satisfies a prior-year RMD is not eligible for rollover.¹⁰ The plan administrator has to separate out the RMD component and pay it directly to you, not into an IRA.

Effect on Social Security

Participants under full retirement age who receive Social Security sometimes worry that a large retroactive pension payment will trip the earnings test. Pension income is generally not “earned income” for Social Security purposes. The Social Security Administration classifies certain post-retirement lump sums as “special payments” that do not count toward the annual earnings limit, provided the work generating the payment was done before Social Security benefits started. A retroactive pension makeup should fall outside the earnings test, but if your total income exceeds $24,480 in 2026 and you are under full retirement age, contact the Social Security Administration to confirm the lump sum qualifies for the exclusion.¹¹

When the Correction Runs Through EPCRS Instead

The RASD regulation and the IRS Employee Plans Compliance Resolution System (EPCRS) address different problems. RASD is a plan design feature authorized by statute to fix underpayments and delayed commencement. EPCRS is an administrative framework for operational and document failures that could otherwise threaten the plan’s tax-qualified status.¹²

EPCRS is the path for overpayments rather than underpayments. Recovery from participants is not always required under EPCRS; the IRS generally treats it as a plan sponsor decision, and in some cases the sponsor can correct a failure by retroactively amending the plan document to match how the plan actually operated. RASD offers no such flexibility, because its focus is restoring benefits that were underpaid or delayed.

In practice, many corrections use both. The plan uses the RASD regulation to set the retroactive date and calculate the makeup, while filing under EPCRS to document the operational failure and protect the plan’s qualification. If you are the participant and something feels wrong about a delayed or miscalculated pension, ask the plan administrator two specific questions: is my plan offering me a retroactive annuity starting date under Treasury Regulation 1.417(e)-1, and is the plan also correcting the underlying failure under EPCRS. The answer to both should usually be yes.
