The IRS raised the annual 401(k) contribution limit to $24,500 for 2026, up from $23,500 in 2025. Workers aged 50 and over can contribute an additional $8,000 in catch-up contributions, bringing their total to $32,500. The most significant change comes from the SECURE 2.0 Act: workers aged 60 through 63 now qualify for a "super catch-up" of $11,250, allowing a maximum contribution of $35,750.
These limits apply to 401(k), 403(b), most 457 plans, and the federal Thrift Savings Plan. IRA limits also increased to $7,500, with a catch-up of $1,100 for those 50 and over, bringing the IRA maximum to $8,600.

The Super Catch-Up: A Four-Year Window
The super catch-up is only available to workers aged 60, 61, 62, or 63. At age 64, the regular catch-up limit of $8,000 applies again. This creates a narrow, four-year window to accelerate retirement savings. Workers who maximize the super catch-up for all four years add an extra $45,000 to their retirement accounts on top of regular contributions.
For someone in the 24% federal tax bracket, contributing the full $35,750 to a Traditional 401(k) reduces taxable income by the same amount, saving $8,580 in federal taxes. The combined benefit of tax savings, employer match, and compound growth makes the super catch-up one of the most valuable provisions in the SECURE 2.0 Act.
"The super catch-up gives workers in their early 60s a powerful tool to close any gap in their retirement savings," said Jean Young, senior research associate at the Vanguard Center for Investor Research. "Four additional years of maximum contributions, including employer matching, can add $200,000 or more by retirement."
The Roth Catch-Up Mandate for High Earners
Starting in 2026, workers who earned $150,000 or more in FICA wages the prior year must make all catch-up contributions on a Roth (after-tax) basis. This means high earners lose the upfront tax deduction on catch-up dollars but gain tax-free withdrawals in retirement.
If your employer's plan does not offer a Roth 401(k) option, you may not be able to make catch-up contributions at all. Check with your HR department now. Plan sponsors have until December 31, 2026, to amend their plans to comply with this requirement.
Strategies to Maximize Your 2026 Contributions
Front-Load Your Contributions
If cash flow allows, increase your contribution percentage early in the year. Contributing 60-70% of your first few paychecks builds a larger base that benefits from 10-11 months of market exposure. Just make sure your plan's match formula does not require contributions across all pay periods to capture the full employer match.
Capture Every Dollar of Employer Match
The median employer match is 4.5% of salary. On a $100,000 salary, that amounts to $4,500 in free money. Failing to contribute at least enough to capture the full match is leaving guaranteed 100% returns on the table.
Consider a Mega Backdoor Roth
If your plan allows after-tax contributions and in-plan Roth conversions, you can contribute beyond the $24,500 limit, up to the total limit of $73,500 (including employer contributions). This strategy is known as the mega backdoor Roth and allows high earners to build substantial Roth balances. Check your plan document or ask your benefits administrator if this option is available.
The Compound Effect
Increasing your annual contribution by $1,000 at age 30 results in approximately $98,000 more at age 65, assuming a 7% average return. Starting the super catch-up at age 60 and contributing $35,750 for four years generates roughly $150,000 in additional savings by age 67 at the same return rate.
Small increases compound over decades. Start with whatever increase you can afford and raise it by 1% of salary each year until you reach the maximum.
