Retirement planning is entering a period of major transition, and Americans mapping out their financial futures will need to keep a close eye on what’s coming.

Several SECURE 2.0 Act provisions are now reshaping 401(k) rules, potentially affecting how workers save and withdraw from their accounts.

Meanwhile, Social Security is moving toward its projected 2034 trust‑fund depletion date, prompting lawmakers to explore legislation aimed at reinforcing the program’s long‑term health.

After years of reporting on retirement issues, I’ve seen how focused people are on learning about these developments and making the most of every opportunity to strengthen their post‑career outlook.

And AARP, the nonprofit advocacy group for older Americans, has been sounding the alarm about these changes, urging future retirees to understand how shifting policies may influence their plans.

“The key provisions of SECURE 2.0 aim to bolster Americans’ opportunities to save for retirement and to draw income from those funds later in life,” wrote AARP. “Most are already in effect; a few more will be phased in over the next several years.”

AARP sounds alarm on 401(k) changes

Some changes are already in place, others are still to come.

“SECURE 2.0 mandated that as of Jan. 1, 2025, employers who start new 401(k) and 403(b) plans must automatically enroll employees and have between 3 percent and 10 percent of their pay directed into their retirement accounts,” AARP warned.

“This provision also has an auto-escalation component, adding 1 percent per year of a worker’s pay to their retirement contributions, up to an employer-set cap that can be from 10 percent to 15 percent of earnings,” AARP added. “Employees can opt out or change the contribution level at any time.

Studies consistently find that people are far more likely to join a retirement plan when enrollment happens automatically rather than requiring them to sign up on their own, according to AARP.

Previously, catch‑up contributions for 401(k)s and similar workplace plans were uniform for everyone age 50 and above. With SECURE 2.0, a special enhanced catch‑up tier for people between 60 and 63 (up to $11,250) took place in 2025.

“In 2026, the standard 401(k) contribution limit is $24,500. The catch-up cap is $8,000, meaning people ages 50-59 and 64-plus can put up to $32,500 into a workplace plan this year,” wrote AARP. “If you are 60, 61, 62 or 63, the catch-up limit is $11,250, and you can contribute up to $35,750 overall.”

AARP explains retirement savings change coming in 2027

Starting in 2027, low‑ and moderate‑income earners will receive a federal match worth 50 percent of their retirement contributions, capped at $2,000. The resulting match — up to $1,000 — will be placed directly into their retirement account.

“This Saver’s Match will phase out at higher income levels,” AARP wrote. “Taxpayers with an adjusted gross income (AGI) of less than $20,500 ($41,000 for a married couple filing jointly) will be eligible to get the full 50 percent.”

“Those making up to $35,500 (individual) or $71,000 (couple) can get a reduced match,” AARP added. “After 2027 the limits will be subject to cost-of-living increases.”

AARP discusses Social Security solvency, when to begin collecting

Instead of drawing on their savings to increase future benefits, many people are choosing to file for Social Security earlier — largely because they’re worried about the program’s long‑term finances, according to the Urban Institute.

But Emerson Sprick, director of retirement and labor policy at the Bipartisan Policy Center, believes lawmakers will act to prevent a Social Security insolvency crisis, according to AARP.

More on personal finance:

“But whether or not you agree, it still likely makes sense to delay filing for Social Security until 70,” Sprick says, as reported by AARP. “Even if overall benefits are reduced, that’s still when you’ll get your biggest possible monthly benefit.”

“With those higher payments … you ultimately may need less in savings for your given lifestyle or expenditure level.”

Another benefit of waiting to claim Social Security is that the program adjusts payments for inflation.

Unlike retirement or investment accounts, which rise and fall with markets, Social Security increases annually through cost‑of‑living adjustments (COLAs) tied to consumer prices.

“Past COLAs are rolled into the benefit you get when you claim, and the bigger that benefit, the more it will grow with future COLAs,” AARP clarified.
