Your Retirement Plan Says It Overpaid You? The IRS Outlines 3 Ways to Pay It Back

Your pension plan may tell you it paid you too much and want the money returned, but before you send a check, the IRS has rules for this situation that may give you more than one repayment option—and picking the wrong one could cost you.

The notice often arrives with little warning. Your pension plan says it overpaid you and wants the excess back. Before taking action, it helps to know the IRS has a specific framework for these cases, and plans can offer more than one way to recover the money.

The relevant guidance is Revenue Procedure 2026-34, the IRS’s updated Employee Plans Compliance Resolution System (EPCRS). Under that guidance, a plan sponsor may allow repayment by “(i) a single-sum repayment, (ii) an installment agreement, or (iii) an adjustment made to future benefit payments.”

What the IRS Treats as an Overpayment

The IRS defines an overpayment as a payment “that exceeded the amount payable to the Overpayment recipient under the terms of the plan or that exceeded a limitation provided in the Code or regulations.” It also includes money paid before the plan or the tax rules allowed a distribution.

The revenue procedure also incorporates Section 301 of the SECURE 2.0 Act, the retirement law Congress passed in December 2022. That section created section 414(aa), which “generally provides that no corrective payment is required for an Inadvertent Benefit Overpayment,” and section 402(c)(12), which gives those payments rollover treatment. But that relief does not apply to failures under sections 401(a)(17), 415, and 436. Section 415 places a ceiling on annual pension benefits, and that limit is the basis for the IRS example below.

The Three Repayment Methods the Plan May Use

1. Single sum. Under the return of overpayment method, the sponsor “must take reasonable steps to have the Overpayment (adjusted for appropriate interest) returned to the plan” and must reduce future payments to the correct amount.
2. Installment agreement. This is the same approach, but repayment is spread out over time. It is not available to a disqualified person or an owner-employee.
3. Smaller future checks. If you receive periodic payments, the adjustment of future payments method lowers each check to the proper amount and then reduces it further to recover the overpayment “over a period not longer than the remaining payment period.”

The important word is “may.” The plan decides whether to offer you a choice. The guidance also says “any other appropriate correction method may be used to correct an Overpayment,” including, in some cases, a plan amendment that retroactively approves the payments.

How the IRS Example Works in Dollar Terms

In IRS Example 21, Employee S retired and started receiving an annual straight life annuity of $290,000. The 2025 section 415(b) limit was $280,000, so an administrative mistake created a $10,000 overpayment. The error was not discovered until the start of 2026.

The correction reduced future payments to the $280,000 limit, then cut them by another $1,000 a year for life. That is because the actuarial present value of $1,000 per year for life equals the $10,000 plus interest. S receives $279,000 in 2026 and in each year after that.

Example 24 includes a tax complication. The notice told S that the excess “was not eligible for tax-free rollover.”

When the Plan Cannot Recover the Full Amount

• Small amounts: If the overpayment is $250 or less, the sponsor does not have to seek repayment or make a corrective contribution.
• Death: If reduced checks recover less than the full overpayment “(for example, due to the death of the Overpayment recipient), the Plan Sponsor is not required to contribute any additional amount to the plan.”
• Surviving spouses: Recovery cuts to the retiree’s checks “do not reduce the amount of the spouse’s survivor benefit.”
• Shortfalls: Under the return method, if a recipient repays less than what is owed, the sponsor or another person “(other than any spouse or beneficiary of the Overpayment recipient)” must cover the difference.

A footnote in the guidance also says that Section 206(h) of ERISA may limit how far a sponsor can go to recover money. This is one of many IRS rules that can quietly affect retirement income.

What to Do Before You Repay Anything

1. Read the notice carefully. Check the principal amount, the interest rate, and whether it says the payment cannot be rolled over.
2. Ask which options the plan provides. Find out whether you can choose a lump sum, installments, or smaller future checks, and whether the error qualifies as an Inadvertent Benefit Overpayment.
3. Keep every record. Save the notice, your payment statements, Forms 1099-R, and all repayment receipts. You may need them if tax reporting must be corrected.

Choosing between repaying now or accepting smaller checks over time can affect both your cash flow and your taxes, so it is wise to review the numbers with a CPA before signing anything.
