Every fall the IRS releases its cost-of-living adjustments, the headlines note that the 401(k) limit went up by a thousand dollars, and most people move on. For 2026, moving on would be a mistake. Yes, the employee 401(k) limit climbed to $24,500 and the IRA limit to $7,500 — modest, expected bumps. But the same set of rules now carries two SECURE 2.0 provisions that don't just tweak a number; they change how catch-up contributions work depending on your age and your paycheck. One is a windfall for people in their early 60s. The other is a curveball for six-figure earners who have always saved pretax. If you're over 50, or getting close, here's what actually changed and how to turn it into more money that's yours in retirement.
The 2026 numbers, at a glance
Start with the baseline, because everything else builds on it. The IRS raised the elective-deferral limit — what you can personally put into a 401(k), 403(b), most 457 plans, and the federal Thrift Savings Plan — to $24,500 for 2026, up from $23,500. The standard catch-up contribution for anyone age 50 or older rose to $8,000, from $7,500.
IRAs got a bump too: the annual contribution limit is now $7,500, up from $7,000, and the 50-plus IRA catch-up rose to $1,100 from a flat $1,000 — the first time that figure has been indexed for inflation. That means an eligible saver 50 or older can put $8,600 into an IRA for 2026.
The full 2026 limits
- 401(k)/403(b)/457/TSP employee deferral: $24,500 (was $23,500)
- Standard catch-up, ages 50-59 and 64+: $8,000 (was $7,500) → total limit $32,500
- 'Super catch-up,' ages 60-63: $11,250 → total limit $35,750
- IRA contribution limit: $7,500 (was $7,000)
- IRA catch-up, age 50+: $1,100 (was $1,000) → total $8,600
- Roth IRA income phase-out, single/head of household: $153,000–$168,000
- Roth IRA income phase-out, married filing jointly: $242,000–$252,000
Move 1: If you're 60 to 63, grab the 'super catch-up'
This is the provision almost nobody is using, and it's the single biggest opportunity in the 2026 rules. Under SECURE 2.0, workers who are ages 60, 61, 62, or 63 during the year get a supersized catch-up of $11,250 instead of the standard $8,000. Layer that on top of the $24,500 base and your personal 401(k) limit for the year hits $35,750.
Here's why the age window matters so much. Say you're 61, earning $130,000, and you've been contributing the old $23,500 max. Bumping to the full $35,750 adds $12,250 of pretax saving in one year. At a combined 24% federal-plus-state marginal rate, that's roughly $2,940 shaved off this year's tax bill — and if that extra money compounds at 7% for the 25 years to age 86, the $12,250 alone grows to about $66,500. The catch: the super catch-up only applies for those four calendar years. The year you turn 64, you drop back to the $8,000 standard catch-up. It is, quite literally, now-or-never money.
Move 2: High earners — check whether your catch-up just became Roth
The second change is a curveball. Beginning January 1, 2026, if you are 50 or older AND earned more than $150,000 in FICA wages from your employer in the prior year (2025), your catch-up contributions must be made as after-tax Roth dollars rather than pretax. The IRS actually raised that trigger from $145,000 to $150,000 in a November 2025 update, so a few people near the line got a reprieve.
It's easy to hear 'must be Roth' as bad news, but it usually isn't. You lose the upfront deduction on the catch-up portion — for 2026 that's up to $8,000, or $11,250 if you're in the 60-63 window — but that money then grows and comes out completely tax-free in retirement. For a high earner who expects to have substantial taxable income later, locking in tax-free growth is often the better long-term deal. The real risk is administrative: if your plan hasn't set up a Roth option, your catch-up could be blocked entirely until it does. That's why this one requires an actual phone call, not a shrug.
Move 3: Don't leave the IRA and the Saver's Credit on the table
The 401(k) is the workhorse, but the IRA is where you get to choose your own investments and, for many, a Roth. For 2026 the Roth IRA income phase-out is $153,000–$168,000 for single filers and $242,000–$252,000 for married couples filing jointly. If you're above those lines, the 'backdoor Roth' — contributing to a traditional IRA and converting — remains legal and unchanged.
At the other end of the income scale, the Saver's Credit is the most overlooked freebie in the tax code. For 2026, a married couple filing jointly with adjusted gross income up to $47,500 can claim a credit worth 50% of what they contribute (up to the limits), and partial credits phase out at $79,500 MFJ / $39,750 single. That's a dollar-for-dollar reduction of your tax bill on top of the money you're already saving for yourself.
Your four-step checklist before your next paycheck
- Recalculate your per-paycheck contribution so you actually hit $24,500 (or your catch-up-boosted limit) by December 31 — don't 'max out' in November and miss the employer match on your final checks.
- If you'll be 60-63 at any point in 2026, confirm your plan supports the $11,250 super catch-up and elect it in writing.
- If you earned over $150,000 in 2025, call your plan administrator and confirm a Roth catch-up option exists so your contributions aren't rejected.
- Check your 2026 modified AGI against the Roth IRA phase-outs, and if you're over the line, ask whether a backdoor Roth or the Saver's Credit applies to your household.
A quick reality check
You do not need to hit the $24,500 max to win. The highest-leverage dollar in any retirement plan is the one that captures your full employer match — that's an instant 50% to 100% return before markets do anything. Secure the match first, then push toward the higher limits as your budget allows.
The 2026 limits reward the people who read past the headline. A bigger cap is nice, but the money is in the details: the four-year super-catch-up window that lets a 61-year-old sock away $35,750, the Roth mandate that quietly reshapes six-figure earners' contributions, and the credits and phase-outs that decide whether your saving is amplified or capped. None of it kicks in automatically — every dollar depends on a contribution election you set. Run your own numbers, adjust your per-paycheck deferral today, and let 2026's rules work for you instead of past you.
