Overview
- Late‑May coverage from major firms and outlets highlights a growing warning: concentrating wealth in pretax 401(k)s and traditional IRAs can force large, taxable withdrawals in retirement and for beneficiaries.
- Fidelity’s Q1 2026 data show a sharp behavioral change with IRA contributions up about 29% year‑over‑year, Roths making roughly two‑thirds of contributions, and Roth conversions rising about 41%.
- Required minimum distributions (RMDs) start in the early 70s and force taxable withdrawals that can push retirees into higher tax brackets, increase taxes on Social Security, and raise Medicare premiums.
- Advisers and firms now promote tax‑bucket diversification — building pretax, after‑tax (taxable), and tax‑free (Roth) accounts through strategies like gradual Roth conversions and coordinated withdrawal timing.
- Practical limits and tradeoffs remain: 2026 IRA contribution limits are $7,500 ($8,600 if 50+), 401(k) employee limits are $24,500 with expanded catch‑up options, and plan fees or limited investment choices can affect whether savers move money out of employer plans.
