Fidelity: Average 401(k) Balance Reaches Record $155,800 in Q2 2026
Fidelity's Q2 2026 data confirms that average 401(k) account balances hit an all-time high of $155,800, while 769,000 savers achieved millionaire status in their workplace plans. Millennials showed the strongest momentum, with average balances climbing 26.1% year over year. However, Fidelity's own analysis notes that average figures are skewed toward older, longer-tenured, and more affluent participants—the median balance sits significantly lower at $44,115.
SECURE 2.0's Hidden Tax Shift: High Earners Must Fill Roth Before Pretax 401(k)
A major change quietly erased a long-standing deduction strategy that millions of high earners relied on. Starting in 2026, employees earning above certain thresholds who want to make catch-up contributions ($8,000 annually for those 50+, or $11,250 for ages 60–63) must direct those catch-up funds into Roth accounts, not traditional pretax 401(k)s. This represents a fundamental tax shift: Roth catch-ups are taxable immediately but grow tax-free, whereas traditional catch-ups were pretax and taxable on withdrawal. The IRS issued final regulations on September 15, 2025, with a good-faith compliance standard applying through 2026, with formal enforcement beginning in 2027.;
Financial advisors emphasize that plan sponsors must now offer Roth contributions for eligible high earners to make catch-up contributions at all.
Principal Financial Faces $4.5 Billion 401(k) Fiduciary Suit Over Proprietary Funds
A new federal lawsuit filed within the past three days alleges that Principal Financial imprudently included "poorly performing" proprietary funds with "unreasonable fees" in its 401(k) plan covering 17,000 participants and $4.5 billion in assets. The suit contends Principal prioritized its own fund products over independent, lower-cost alternatives—a classic self-dealing claim under ERISA. This case joins a wave of recent target-date fund underperformance litigation and reflects growing scrutiny of plan menu conflicts of interest.
Target-Date Funds Face Dual Pressure: Private Equity Creep and Fee Lawsuits
Plan sponsors and fiduciaries are under pressure from two directions. First, private equity is "quietly creeping" into target-date fund lineups, raising liquidity and valuation concerns for retirement savers. Second, a tsunami of lawsuits targeting specific target-date fund families has intensified over the past 18 months, alleging underperformance relative to benchmarks and hidden fee conflicts. A Forbes opinion piece published October 2, 2026, highlighted the need for plan sponsors to carefully weigh target-date funds against alternative model portfolio approaches to avoid fiduciary liability.;
