Top developments
Wells Fargo Hit With Major 401(k) Fiduciary Lawsuit
In a significant legal development for retirement plan participants, workers filed a proposed class action against Wells Fargo in Minnesota federal court just days ago. The suit alleges that underperforming and costly funds within the company's 401(k) plan breached fiduciary duties of prudence, resulting in at least $1 billion in losses for participants. This case adds to a growing wave of ERISA litigation targeting large financial institutions over their management of target-date funds and fee structures.
SSA to Announce 2027 COLA on October 14
The Social Security Administration (SSA) has confirmed that it will announce the 2027 cost-of-living adjustment on Wednesday, October 14, 2026. This announcement is crucial for retirees as it determines the percentage increase in monthly benefits to account for inflation. The timing of this release is a key calendar event for all US beneficiaries, influencing budgeting and financial planning for the upcoming year.
Mandatory Roth Catch-Up Rules Drive Planning Shifts
Recent guidance highlights the ongoing impact of SECURE 2.0 regulations requiring high earners to make catch-up contributions on a Roth basis. Individuals who earned more than $145,000 (indexed to $150,000 for some contexts) in the previous year must now direct catch-up contributions into Roth accounts. Financial advisors are urging workers aged 50+ to rethink their contribution strategies to optimize tax efficiency under these new mandatory structures.
Q4 Retirement Deadlines Approaching
As the year draws to a close, multiple critical deadlines for retirement accounts are approaching before 2027. These include final opportunities for certain 401(k) contributions, Roth conversions, and Medicare-related actions. Missing these dates can result in lost tax advantages or penalties, prompting media outlets to issue urgent reminders for savers to review their accounts immediately.
Local view
Spanish-language media outlets are actively clarifying Social Security payment schedules for Hispanic beneficiaries in the US. El Cronista and Clarín have published detailed calendars explaining that some beneficiaries may receive multiple payments in October due to the alignment of Supplemental Security Income (SSI) and regular Social Security deposit dates. These reports emphasize that certain deposits, particularly around October 30, are not "bonuses" but rather standard payments shifted due to weekend or holiday scheduling, aiming to reduce confusion among non-English speaking recipients.
Context & numbers
- Medicare Part B Premium: For 2026, the standard monthly premium for Medicare Part B is set at $202.90. Higher-income individuals face additional income-related adjustments if their modified adjusted gross income exceeds $109,000 (individual) or $218,000 (joint).
- 401(k) Balance Disparity: Recent data indicates a stark difference between average and median 401(k) balances. While the average balance sits at approximately $167,970, the median is significantly lower at $44,115, highlighting that a small number of very large accounts skew the average upward.
On the radar
- October 14, 2026: The official release of the 2027 Social Security COLA percentage.
- October 30, 2026: A key payment date for certain SSI and Social Security beneficiaries, often causing confusion about whether it represents an extra payment or a schedule shift.
- Ongoing Litigation: Watch for further rulings or settlements in the expanding class-action lawsuits against major plan providers regarding target-date fund fees and performance.
