Giới hạn đóng góp 401k thay đổi vào năm 2026

What happened: The 2027 Social Security Cost-of-Living Adjustment (COLA) is projected at 3.9%, potentially increasing checks and taxes for retirees. A new SECURE 2.0 rule, effective January 2026, mandates Roth 401(k) catch-up contributions for high earners, while 401(k) contribution limits remain unchanged at $24,500 for under-50s and $32,000 for over-50s.

Market impact: Retirees may face higher taxes, impacting their financial planning. High-income earners must adjust their savings strategies due to the Roth catch-up requirement. Financial advisors and retirement plan providers should update their services to reflect these changes.

What to watch next: The official 2027 COLA announcement in October 2026 will confirm the exact increase. In January 2026, monitor the impact of the Roth catch-up requirement on high earners' 401(k) contributions.
