$23,500. That's how much you can put into your 401(k) this year. Congress didn't hand you that number by accident. The SECURE 2.0 Act of 2022 has been rolling out changes to retirement accounts in stages, and 2025 was a big one. Financial media covered it like it was a revolution. It's not. But a few pieces of it are genuinely useful, and one of them might be sitting in your benefits portal right now, quietly doing something you don't know about.
Most of SECURE 2.0's headlines went to the complicated stuff: Roth catch-up rules, required minimum distribution age changes, annuity tweaks. That's the content made for people who already have a lot of money and are trying to optimize it. If you're still building, most of that conversation isn't for you yet. What matters to you is simpler, and honestly, more interesting.
The Auto-Enrollment Rule Is the Most Important Thing Nobody Is Talking About
If you started a new job after December 29, 2022, and your employer set up a new 401(k) plan, the legislation requires businesses adopting those new plans to automatically enroll eligible employees, starting at a contribution rate of at least 3%, beginning in 2025. And it doesn't stop there. That rate must increase by at least 1% annually until reaching at least 10%, but no more than 15%.
Read that slowly. Your employer is now legally required to slowly ratchet up how much you save over time, unless you tell them to stop. This is behavioral finance doing the heavy lifting for you. The whole reason people don't save enough is that saving requires an active decision and spending requires none. Auto-enrollment flips that. Automatic enrollment automatically enrolls eligible employees at a preset default contribution rate, unless they actively opt out. The feature aims to simplify participation and increase retirement savings rates among employees.
Your action item this week: Log into your benefits portal and find out what rate you're enrolled at. If it's 3%, know that's the floor, not the recommendation. You want to be at least at whatever your employer matches, because free money is free money. Then set a calendar reminder to increase your contribution by 1% every January, if your plan doesn't do it for you automatically. That's it. That's the whole strategy.
The Catch-Up Changes Are Real, But They're for Future You
This is where SECURE 2.0 gets genuinely exciting, if you're patient enough to care about something that helps you in 20 years. Starting January 1, 2025, individuals attaining ages 60 to 63 during the calendar year can make catch-up contributions of $11,250, in place of the normal $7,500 catch-up. To put that in real terms: participants aged 60, 61, 62, or 63 can contribute up to $34,750 in 2025 ($23,500 plus $11,250).
Plan sponsors have moved fast on this. By year-end 2025, 91% of Vanguard-administered plans had implemented the higher catch-up limit. And people are using it: two-thirds of catch-up contributors exceeded the standard limit, and about one-quarter directed some portion of those dollars to Roth, signaling growing interest in tax diversification.
If you're not 60 to 63, file this away and move on. The version of you a couple decades from now will thank the version of you today who just kept investing consistently and didn't stress about the catch-up rules. That's the whole point. Compound growth means the money you put in at 28 is worth dramatically more than the money you scramble to stuff in at 62. The catch-up provision exists for people who didn't start early enough. Starting early is better.
One thing worth knowing about the coming Roth twist: starting in 2026, if you earn more than $150,000 in the prior calendar year, all catch-up contributions to a workplace plan at age 50 or older will need to be made to a Roth account in after-tax dollars. If you're not in that income bracket, this doesn't touch you. If you are, your accountant should already know about it.
The One New Rule That Could Actually Help You Right Now
This is the provision that got the least attention and probably deserves the most, especially if you're in your 20s or early 30s carrying student loans. A provision in SECURE 2.0 allows employers to match student loan payments with contributions to an employee's retirement plan. Starting in 2025, employees who are focusing on paying down their student loans can still receive employer matching contributions to their retirement accounts, even if they are not currently contributing to the plan themselves. This ensures that workers are not penalized for prioritizing debt repayment over retirement savings.
This one is opt-in for employers, meaning your company has to decide to offer it. But if they do, it solves one of the most painful early-career trade-offs in personal finance. My hierarchy is still what it is: emergency fund first, then get your employer match, then tackle high-interest debt, then max your Roth IRA. But student loans at a low interest rate while also missing out on your employer match? That's a math problem. This provision makes it less of one. Call HR and ask if your company has adopted it. The worst they can say is no.
The 401(k) limit for 2026 also just went up. The annual contribution limit for employees in 401(k) plans increased to $24,500, up from $23,500 for 2025. If you're maxing it out, adjust your contribution percentage slightly so you hit that new ceiling. If you're nowhere near maxing it, don't let the number intimidate you. Put in what you can, automate it, and increase it by 1% every year. You are closer than you think.
