Important 401(k) Changes for 2026
As more older Americans near retirement, there’s a growing focus on increasing 401(k) savings to handle soaring medical bills and daily expenses. According to financial experts, it’s crucial to stay informed about upcoming changes to 401(k) plans in 2026.
Jun Um, a certified financial planner at Secure Tax and Accounting in Hayward, California, stresses that “the little details of your 401(k) are more important than ever” this year.
Starting in 2026, individuals can defer up to $24,500 into their 401(k) plans, slightly up from the $23,500 limit in 2025. When it comes to total contributions—including employer matching, profit-sharing, and other additions—the cap reaches $72,000.
For those aged 50 and older, catch-up contributions will also rise. In 2026, you’ll be able to contribute an additional $8,000 annually, compared to $7,500 in 2025. For “super catch-up” savers aged 60 to 63, the limit will remain at $11,250.
Additionally, the contribution limits for individual retirement accounts will increase in 2026, with a new cap of $7,500, up from $7,000 in the previous year. Those over 50 can contribute an extra $1,100, as opposed to $1,000 the year before.
These updates come amid concerns that many older Americans feel ill-equipped for retirement. A New York Life survey indicated that more than one-third of U.S. adults have postponed retirement plans. The primary reasons cited were insufficient savings and inflation.
Defined contribution plans like 401(k)s serve as crucial retirement saving tools for a vast majority of private-sector workers in the U.S. In 2023, participant numbers in these plans are expected to surpass 100 million, based on insights from the Labor Department.
Understanding 401(k) Limits
Um highlights that while higher deferral limits are beneficial, they will only make a difference if contributions truly reflect these adjustments.
According to Vanguard’s “How America Saves” report for 2025, about 45% of participants increased their 401(k) contributions, either voluntarily or through automatic adjustments. Yet, only around 14% actually maxed out their 401(k) accounts, with the average savings rate, including employer contributions, estimated at about 12%.
“We encourage customers to take a fresh look at this early in the year,” Um advised.
Roth Catch-Up Contributions for High-Income Earners
If you’re 50 or older, your catch-up contributions can be either traditional pre-tax or after-tax Roth, depending on your plan. However, starting in 2026, specific high-income individuals will have restrictions on their contributions. Higher earners will need to refer to the provisions of the Secure 2.0 law changes implemented in 2022.
Neil Krishnaswamy, a CFP and wealth planner in McKinney, Texas, has been guiding clients through adjustments to their 401(k)s. In 2026, most catch-up contributions are set to be Roth-based for those earning over $150,000. You can check your eligibility by looking at your gross income on your last payslip from 2025.
Interestingly, if you start a new job on January 1, 2026, the “Roth requirement” won’t apply to you, even if your previous job paid you well. The same goes for those exceeding the income limit by working for multiple employers.
