Archived Summary of 2025 Developments
By the start of 2025, most retirement plan sponsors were no longer asking what SECURE 2.0 meant. They were asking whether their systems were actually ready.
The year did not introduce sweeping new retirement legislation. Instead, it tested implementation. Provisions that had been discussed for months moved into payroll logic, eligibility reports, participant notices, and amendment calendars. In many cases, 2025 was the first year those processes operated without transition relief.
This page reflects the regulatory and operational themes that shaped plan administration during 2025. For current developments, visit our 2026 Employee Benefit Plan Regulatory Updates page.

Automatic Enrollment Became Real
SECURE 2.0 requires certain newly adopted 401(k) and 403(b) plans to include automatic enrollment beginning in 2025. On paper, the requirements were straightforward: default deferral rates between 3% and 10%, annual escalation, and participant opt-out rights.
In practice, the work was operational.
Plans established before December 29, 2022, were exempt, along with certain small or newer employers. But for organizations subject to the rule, this was the first year that default percentages and escalation features needed to function correctly across payroll and recordkeeping systems.
For some sponsors, the complexity wasn’t the percentage itself. It was ensuring that opt-outs, mid-year hires, and compensation definitions were coded accurately from day one.
Contribution Limits Required Early System Confirmation
The IRS announced 2025 cost-of-living adjustments in late 2024. As usual, elective deferral limits, catch-up thresholds, compensation caps, and annual addition limits increased.
The numbers were not surprising.
The timing was.
Organizations that confirmed payroll configuration before the first pay cycle moved through the year without incident. Those who delayed sometimes discovered excess contribution issues after several pay periods had already run.
In most cases, the root cause was simple: system updates lagged announcements.
For broader compliance considerations tied to annual testing and contribution monitoring, see our 401(k) Compliance & Audit Guide.
Roth Catch-Up Rules Shifted From Theory to Configuration
One of the more technical adjustments in 2025 involved final regulations clarifying Roth treatment of catch-up contributions for certain higher-income participants.
This change required more than policy awareness. Payroll systems needed to identify participants above the income threshold and apply Roth treatment correctly. Compensation tracking and recordkeeping systems had to align.
When the configuration was incomplete, the issue typically surfaced mid-year, after contributions had already been processed.
For many sponsors, this provision illustrated the broader theme of 2025: legislation that appeared narrow in scope could require significant system coordination behind the scenes.
For detailed implementation considerations, see our SECURE Act & SECURE 2.0 Implementation Guide.
Long-Term Part-Time Eligibility Became More Visible
Long-term part-time eligibility rules did not originate in 2025, but reduced service thresholds under SECURE 2.0 increased their impact.
Employers revisited hour tracking and eligibility determination processes, particularly for variable-hour employees. One frequently overlooked detail was that service completed before January 1, 2021, does not count toward eligibility or vesting for these provisions.
Inaccurate enrollment decisions carry correction obligations. As participation expanded, eligibility tracking became a more frequent audit focus area.
Optional Long-Term Care Distribution Feature
SECURE 2.0 introduced an optional provision allowing certain distributions for qualified long-term care insurance premiums without triggering the early withdrawal penalty, subject to statutory limits.
Because adoption was not mandatory and effectiveness was tied to distributions after December 29, 2025, many sponsors paused to evaluate whether to incorporate the feature.
The discussion was often practical. Would recordkeepers support the process smoothly? Would participant communications require updates? Would administration add complexity without meaningful uptake?
For some organizations, the feature remained under consideration rather than immediate implementation.
Amendment Tracking Required Discipline
The IRS released its 2025 Required Amendments List, identifying provisions that must eventually be incorporated into plan documents.
Operational changes and amendment deadlines do not always occur in the same year. Plans may operate under updated rules while formal restatement timelines extend into future cycles.
That sequencing is allowed. The risk arises when documentation lags too long.
During audits, inconsistencies between written terms and operational practice tend to surface quickly. Several organizations strengthened amendment tracking processes in 2025 to avoid compressed adoption timelines later.
Maintaining a simple calendar of required updates proved more effective than revisiting deadlines only when filing season approached.
Forfeitures Remained Routine — and Scrutinized
The Department of Labor revisited the use of forfeitures in defined contribution plans during 2025. The clarification did not dramatically change existing practices.
It reinforced consistency.
If forfeitures were used to offset employer contributions, pay plan expenses, or allocate additional contributions, those uses needed to align with plan language and be applied consistently from year to year.
Examinations did not focus on creativity. They focused on whether written terms matched actual allocation patterns.
For operational best practices, see our 401(k) Compliance & Audit Guide.
Correction Programs Continued to Evolve
Regulators continued refining digital submission processes for correction programs. In some situations, expanded self-correction flexibility provided sponsors with additional options when operational errors were identified internally.
Timing mattered.
When issues were addressed early, correction pathways remained broader. Once regulatory examinations began, flexibility narrowed and documentation demands increased.
For detailed correction guidance, see our Correction Programs Guide for Retirement Plan Sponsors.
Form 5500 Filing Pressures Were Familiar
For calendar-year plans, July 31, 2025, remained the standard filing deadline, with extensions available through October 15 upon timely submission of Form 5558.
Plans crossing the 100-participant threshold were required to include audited financial statements with their filings.
In several cases, sponsors discovered threshold changes late in the reporting cycle. In others, filings were delayed due to missing audit attachments or inaccurate participant counts.
Early review of reporting classification reduced deadline pressure significantly.
For filing procedures and audit attachment requirements, see our Form 5500 Filing & Audit Requirements Guide.
The “Lost and Found” Database Took Shape
SECURE 2.0 required the Department of Labor to establish a searchable retirement plan database to help participants locate prior employer benefits.
By 2025, sponsors were beginning to see how the initiative would function operationally. Questions centered on data expectations, update frequency, and information security considerations.
While the concept was broadly supported, many organizations monitored guidance before adjusting internal reporting processes.
Enforcement Activity Felt Steady
Enforcement priorities in 2025 did not shift dramatically. Late participant contribution deposits, incomplete Form 5500 filings, eligibility tracking gaps, hardship documentation issues, and document inconsistencies remained common areas of review.
What became more noticeable was the emphasis on documentation.
When records were clear, reviews progressed efficiently. When documentation was incomplete, even minor operational issues required extended explanation.
The pattern reinforced a simple principle: operational discipline must be supported by written records.
For correction pathways, see our Correction Programs Guide for Retirement Plan Sponsors.
Defined Benefit Oversight Continued
Defined benefit sponsors continued monitoring minimum funding requirements, actuarial assumption updates, PBGC premium calculations, and timely employer contributions.
Because pension plans carry long-term financial obligations, oversight remained steady rather than reactive.
For pension-specific audit considerations, see our Defined Benefit & Pension Plan Audit Guide.
Looking Back at 2025
If one theme defined 2025, it was execution.
Legislative changes moved from interpretation into daily operations. Payroll configuration, eligibility tracking, amendment timing, and audit planning required closer coordination than in prior years.
Organizations that addressed implementation early generally experienced fewer corrective actions and smoother reporting cycles.

Looking Ahead
While 2025 centered on implementation and clarification, regulatory oversight continues to evolve.
Sponsors should periodically revisit prior-year changes to confirm operational alignment, document adoption, and audit readiness.
