Many Americans face a retirement savings shortfall. However, setting aside more money could get easier for some older workers in 2025.

Enacted by Congress in 2022, the Secure Act 2.0 ushered in several retirement system improvements, including updates to 401(k) plans, required withdrawals, 529 college savings plans and more.

While some Secure 2.0 changes have already happened, another key change for “max savers,” will begin in 2025, according to Dave Stinnett, Vanguard’s head of strategic retirement consulting.

Some 4 in 10 American workers are behind in retirement planning and savings, according to a CNBC survey, which polled roughly 6,700 adults in early August.

But changes to 401(k) catch-up contributions — a higher limit for workers age 50 and older — could soon help certain savers, experts say. Here’s what to know.

Employees can now defer up to $23,000 into 401(k) plans for 2024, with an extra $7,500 for workers age 50 and older.

But starting in 2025, workers aged 60 to 63 can boost annual 401(k) catch-up contributions to $10,000 — or 150% of the catch-up limit — whichever is greater. The IRS hasn’t yet unveiled the catch-up contribution limit for 2025.  

“This can be a great way for people to boost their retirement savings,” said certified financial planner Jamie Bosse, senior advisor at CGN Advisors in Manhattan, Kansas.

An estimated 15% of eligible workers made catch-up contributions in 2023, according to Vanguard’s 2024 How America Saves report.

Those making catch-up contributions tend to be higher earners, Vanguard’s Stinnett explained. But they could still have “real concerns about being able to retire comfortably.”

More than half of 401(k) participants with income above $150,000 and nearly 40% with an account balance of more than $250,000 made catch-up contributions in 2023, the Vanguard report found.

Another Secure 2.0 change will remove the upfront tax break on catch-up contributions for higher earners by only allowing the deposits in after-tax Roth accounts.

The change applies to catch-up deposits to 401(k), 403(b) or 457(b) plans who earned more than $145,000 from a single company the prior year. The amount will adjust for inflation annually. 

However, IRS in August 2023 delayed the implementation of that rule to January 2026. That means workers can still make pretax 401(k) catch-up contributions through 2025, regardless of income.
