IRS Retirement Plan Error Corrections: New Rules for Employers
Business owners who discover mistakes in their retirement plans may have more options for correcting those errors under updated IRS procedures effective October 22, 2026. Revenue Procedure 2026-34 expands the Employee Plans Compliance Resolution System, allowing qualifying employers to correct certain failures without submitting a formal application to the IRS.
The changes apply to several common employer retirement arrangements, including 401(k) plans, SEP arrangements, and SIMPLE IRA plans.
Retirement plan errors are not limited to excessive contributions. Problems can arise when an employer excludes an eligible employee, makes an incorrect contribution, fails to follow the plan document, or incorrectly determines which employees qualify for benefits.
These mistakes can affect employee retirement balances, employer tax deductions, and the tax favored status of the plan.
The revised rules provide additional correction opportunities, but they do not eliminate the underlying obligations. Employers must still determine the appropriate correction method, restore affected benefits when required, and maintain records demonstrating that the correction was completed properly.
Reviewing retirement plan administration should be part of broader proactive business and retirement tax planning, particularly when payroll records, employee eligibility, and year end contributions are being reconciled.
Key takeaway:
Revenue Procedure 2026-34 expands the IRS Self-Correction Program for eligible inadvertent retirement plan failures.
Qualifying employers may be able to correct certain mistakes without IRS approval or a user fee.
However, eligibility depends on the nature of the failure, the existence of established compliance procedures, the timing of correction, and whether the plan or employer is under IRS examination.
Revenue Procedure 2026-34 Updates the IRS Retirement Plan Correction System
On October 22, 2026, the IRS issued Revenue Procedure 2026-34, replacing and restructuring the correction framework previously established under Revenue Procedure 2021-30.
The updated procedure incorporates provisions of the SECURE 2.0 Act of 2022, including Section 305, which expanded the availability of self correction for eligible inadvertent failures.
Some of this relief was previously available through interim IRS guidance. Revenue Procedure 2026-34 consolidates and modifies that guidance in a comprehensive correction procedure.
The revised program applies to qualifying plans under Section 401(a), certain Section 403(b) arrangements, SEP arrangements under Section 408(k), and SIMPLE IRA plans under Section 408(p), among others.
The appropriate correction process depends on the type of retirement plan and the particular failure.
Employers Have Three IRS Correction Programs
The Employee Plans Compliance Resolution System, commonly called EPCRS, provides three principal correction methods.
| Correction program | How it generally works | Principal consideration |
|---|---|---|
| Self-Correction Program (SCP) | Qualifying failures are corrected without a formal IRS application or user fee. | The employer must satisfy the eligibility, correction, and documentation requirements. |
| Voluntary Correction Program (VCP) | The employer submits a proposed correction to the IRS and generally pays a user fee. | The program ordinarily must be used before the plan or employer comes under examination. |
| Audit Closing Agreement Program (Audit CAP) | The employer corrects eligible failures identified during an IRS examination under an agreement involving an appropriate sanction. | The consequences generally differ from those available through voluntary correction. |
The expanded Self-Correction Program is the most significant development for many small business owners.
However, the availability of SCP should never be assumed merely because a mistake was unintentional.
More Retirement Plan Errors May Qualify for Self Correction
The revised procedure expands the types of eligible inadvertent failures that may be corrected through SCP.
Depending on the applicable requirements, these may include operational failures, certain plan document failures, employer eligibility failures, demographic failures, and qualifying plan loan failures.
Operational Failures
An operational failure generally occurs when a retirement plan is not administered according to its written terms or applicable tax qualification requirements.
Examples may include:
- Failing to include an employee who satisfied the plan's eligibility requirements.
- Calculating employer contributions using incorrect compensation.
- Failing to provide an employer matching contribution required by the plan.
- Applying an incorrect vesting percentage.
- Failing to follow required contribution limits or other applicable plan provisions.
The appropriate correction depends on the specific failure. In many circumstances, the employer must restore the benefit that affected employees should have received.
Plan Document Failures
A plan document failure can arise when the written retirement plan does not contain a required provision or is not timely amended.
Revenue Procedure 2026-34 expands the availability of SCP for certain plan document failures.
However, the initial failure to adopt a required written plan remains excluded from SCP under Section 7.03(1).
Therefore, an employer that never properly established a written retirement plan should not assume that the omission can be corrected without an IRS submission.
Employer Eligibility and Demographic Failures
The expanded rules also address certain employer eligibility failures and failures involving employee coverage or nondiscrimination requirements.
These categories are more technical than an ordinary contribution calculation mistake.
A correction may require changes in participation, additional contributions, or discontinuation of contributions when the employer was not eligible to maintain the arrangement.
Revenue Procedure 2026-34 establishes special requirements for these failures, including restrictions on permissible correction methods.
Self Correction Requires Established Compliance Procedures
One of the most important eligibility requirements is that the plan sponsor or administrator must have established practices and procedures reasonably designed to promote compliance with the applicable retirement plan rules.
These procedures can be formal or informal.
However, Section 7.02 of Revenue Procedure 2026-34 specifically provides that possession of a plan document alone does not establish the existence of adequate procedures.
The procedures generally must have been in place and routinely followed, with the failure arising from oversight or a mistake in applying them.
For example, an employer might maintain a process for reviewing employee eligibility each year but inadvertently overlook an employee whose hours or service history were incorrectly recorded.
The existence of an established review process can be relevant in determining whether the error is an eligible inadvertent failure.
By contrast, an employer that never established any process for determining employee eligibility may have greater difficulty satisfying the SCP requirements.
Revenue Procedure 2026-34 also excludes certain failures involving egregious conduct, diversion or misuse of plan assets, and abusive tax avoidance transactions.
The fact that an employer did not intend to violate the law does not, by itself, establish eligibility for self correction.
The New Rules Provide a More Flexible Correction Period
Revenue Procedure 2026-34 generally requires an eligible inadvertent failure to be corrected within a reasonable period after the employer identifies the mistake.
Section 7.05 establishes a specific standard under which a correction is deemed to have been completed within a reasonable period.
Under the general rule, the correction is considered timely for this purpose if completed by the later of:
- The last day of the third plan year following the plan year in which the failure occurred.
- 18 months after the plan sponsor identifies the failure.
The rule provides flexibility when an employer discovers an error from an earlier year.
However, the time period should not be interpreted as an unconditional extension for every retirement plan failure.
Certain nondiscrimination testing failures and employer eligibility failures have special correction rules.
The availability of SCP can also change when the IRS begins examining the plan or plan sponsor.
Important deadline distinction:
The later of the third following plan year or 18 months after identification is a standard for determining whether a correction is completed within a reasonable period.
It does not eliminate the requirement to correct the error appropriately, satisfy other eligibility conditions, or address special deadlines that apply to particular failures.
SEP and SIMPLE IRA Plans Have Important Special Rules
The expanded correction program can be particularly relevant to small businesses using SEP or SIMPLE IRA arrangements.
These plans often have less administrative complexity than larger employer retirement plans, but their eligibility and contribution requirements remain significant.
For example, a business maintaining a SEP arrangement may discover that an employee who satisfied the plan's age, service, and compensation requirements was incorrectly excluded from an employer contribution.
Likewise, a business maintaining a SIMPLE IRA plan may discover that required employer contributions were calculated incorrectly or that an eligible employee did not receive the opportunity to make elective deferrals.
Revenue Procedure 2026-34 can provide correction options for these failures.
Not Every SEP or SIMPLE Plan Qualifies for SCP
Section 7.03 contains specific plan document restrictions.
For SEP arrangements, SCP eligibility generally requires an appropriate valid model form or a qualifying prototype arrangement satisfying the applicable requirements.
For SIMPLE IRA plans, the procedure similarly specifies qualifying model forms or qualifying prototype arrangements.
These provisions make it important to identify the actual governing plan document before selecting a correction method.
A business should not assume that an IRA account statement or evidence of prior contributions is sufficient to establish the required plan documentation.
Missed SEP and SIMPLE Contributions Generally Require Earnings
Section 6.17(3) of Revenue Procedure 2026-34 addresses undercontributions to SEP and SIMPLE IRA arrangements.
The general correction requires the plan sponsor to make appropriate contributions that are fully vested, adjusted for earnings from the date of the failure through the correction date.
Consequently, simply depositing the original amount of an omitted contribution may not constitute a complete correction.
The earnings calculation must be determined using the applicable correction principles and supporting records.
Example: A Business Excluded an Eligible Employee From Its SEP
Assume the following facts:
- A business maintains a SEP arrangement using a qualifying written plan document.
- The employer has an established annual process for reviewing eligible employees.
- During preparation of its 2026 financial records, the employer discovers that one eligible employee was omitted from its 2025 SEP contribution calculation.
- The omission resulted from an error in the employee eligibility records.
- The employer was not under IRS examination when the failure was identified.
The employer should first determine whether the omission constitutes an eligible inadvertent failure under Revenue Procedure 2026-34.
If SCP is available, the employer may be able to correct the omission without submitting a VCP application.
The correction generally involves determining the contribution the employee should have received and making the appropriate fully vested corrective contribution, adjusted for earnings.
The employer should also document when the error was discovered, why it occurred, how the calculation was performed, and what changes were made to prevent recurrence.
The appropriate treatment of the corrective contribution for federal and state income tax purposes requires a separate analysis based on the years involved and the applicable deduction rules.
The example illustrates the potential benefit of the expanded Self-Correction Program. Actual eligibility must be determined from the governing plan document, the nature of the error, and the applicable procedural requirements.
IRS Examination Can Restrict Self Correction
The timing of an employer's discovery and corrective action can be particularly important if an IRS examination begins.
Under Section 8 of Revenue Procedure 2026-34, SCP may remain available during an examination in specified circumstances.
These include certain insignificant operational failures and situations in which the employer demonstrated a specific commitment to implementing the correction before coming under examination.
A general statement that the employer intends to correct any future errors is not sufficient to demonstrate a specific commitment.
The IRS evaluates whether the employer was actively pursuing correction based on the facts and circumstances.
This is one reason to document retirement plan errors promptly rather than postponing analysis until the next income tax return is prepared.
Employers that identify retirement plan errors can incorporate their review into a broader assessment of business tax planning and compliance.
Excess Contributions May Require a Different Correction Method
Not every retirement plan error involves an underpayment.
A business may contribute more than the permitted amount, calculate employee compensation incorrectly, or exceed an applicable statutory contribution limitation.
The correct treatment of excess amounts depends on the type of plan, the source of the excess, and the applicable correction method.
Revenue Procedure 2026-34 contains specific provisions addressing excess amounts in SEP and SIMPLE IRA arrangements.
Importantly, Section 7.03(4) excludes SCP for certain SEP and SIMPLE IRA failures when the proposed correction would allow an excess amount to remain in the employee's IRA.
The procedure also contains rules addressing appropriate distributions, reporting, and potential sanctions.
Therefore, an employer should not assume that an excessive contribution can be corrected simply by reducing a later year's contribution.
The applicable limits should be verified for the year of the failure. See the related discussion of 2026 retirement plan contribution limits.
Owner Compensation and Payroll Errors Can Affect Retirement Plans
Retirement plan corrections may involve more than the amount deposited into a retirement account.
The employer should also determine whether compensation was classified correctly and whether the plan used the proper definition of compensation.
For example, the federal tax treatment of an owner of a partnership differs from that of a corporate employee.
An incorrect classification can affect payroll reporting, retirement plan calculations, and the tax returns on which related amounts are reported.
For further discussion, see how an incorrectly issued Form W-2 to an LLC member or partner can affect tax reporting.
A retirement plan correction should be coordinated with any required payroll, information return, partnership, or S corporation return adjustments.
Revenue Procedure 2026-34 does not automatically correct those separate tax reporting obligations.
Correcting the Plan Does Not Automatically Resolve Every Tax Issue
An employer may need to address several distinct consequences when a retirement plan failure is identified.
These can include:
- Restoring missed employee benefits or contributions.
- Calculating associated earnings.
- Correcting plan documents or administrative procedures.
- Evaluating federal income tax deductions.
- Determining whether prior business tax returns require amendment.
- Reviewing applicable Forms 1099-R, W-2, or other information reporting.
- Evaluating Form 5500 reporting requirements.
- Determining whether separate excise taxes or penalties apply.
- Coordinating any required California or other state income tax adjustments.
The appropriate treatment depends on the particular failure.
In addition, EPCRS does not replace separate correction procedures administered by the Department of Labor.
For example, certain fiduciary violations or failures involving the timely deposit of employee contributions may create obligations under ERISA that are not fully resolved through an IRS plan qualification correction.
Section 6.19 of Revenue Procedure 2026-34 expressly recognizes that correction under EPCRS does not change obligations under other applicable law.
The IRS Also Created a Separate IRA Correction Program
The IRS issued Revenue Procedure 2026-33 on the same date as the updated employer plan correction procedure.
That separate procedure establishes the IRA Compliance Resolution System, or ICRS.
Unlike Revenue Procedure 2026-34, which is effective October 22, 2026, the new IRA procedure becomes effective May 1, 2027.
ICRS provides a framework for specified IRA failures and certain requests for relief involving the 60 day rollover requirement.
The initial system includes the IRA Voluntary Correction Program.
However, the new system does not eliminate existing automatic waiver and self certification relief for qualifying rollover failures.
Business owners should distinguish mistakes involving an employer sponsored SEP or SIMPLE IRA plan from errors involving the administration of an individual's IRA.
Although both arrangements may involve IRA custodians, different correction rules can apply.
What Business Owners Should Review Before Year End
The release of Revenue Procedure 2026-34 creates an opportunity to review retirement plan administration while 2026 payroll and accounting records are still available.
A practical review should address:
- Whether every employee who satisfied the plan's eligibility requirements was included.
- Whether employer contributions were calculated using the correct compensation.
- Whether required matching or other contributions were made.
- Whether employee deferrals were implemented correctly through payroll.
- Whether contribution limits and applicable testing requirements were satisfied.
- Whether the business maintains the required current written plan document.
- Whether established procedures exist for reviewing plan eligibility and contributions.
- Whether prior errors were corrected and supporting documentation was retained.
- Whether any identified correction creates an additional federal or state income tax reporting requirement.
The review should extend to prior years when available records suggest that an error did not begin in 2026.
The employer should also preserve the date each failure was identified because that date can affect the applicable correction period.
When an error is discovered, the appropriate next step is to determine the type of failure, identify the available correction program, and establish a documented correction method.
Final Takeaway
Revenue Procedure 2026-34 expands the circumstances in which employers can correct eligible inadvertent retirement plan failures without submitting a formal application to the IRS.
The change is particularly relevant to business owners maintaining 401(k), SEP, and SIMPLE IRA arrangements.
However, the expanded program does not provide unrestricted relief for every mistake.
Employers must still satisfy the applicable eligibility standards, maintain adequate compliance procedures, complete corrections within the required period, and restore affected benefits when necessary.
The most important practical consideration is to identify and evaluate errors before an IRS examination begins.
A properly documented correction can help preserve the intended tax treatment of the retirement plan while addressing benefits owed to affected employees.
