If you're a business owner between 60 and 63, the tax code just handed you a four-year window to shovel an extra $11,250 into your 401(k) — on top of everything you were already allowed to save. Miss the window and it's gone: turn 64 and you drop back to the standard catch-up amount for good.
Here's what the "super catch-up" actually is, who qualifies, and a compliance trap buried in the same law that could quietly cost high earners their catch-up contribution entirely if their plan isn't ready.
What Changed: The Super Catch-Up, Explained
Under the SECURE 2.0 Act, anyone 50 or older can already make a standard "catch-up" contribution above the normal 401(k) deferral limit. For 2026, that regular limit is $24,500, and the standard 50-plus catch-up adds $8,000, for a combined $32,500.
Starting in 2025, a new tier kicked in specifically for savers who turn 60, 61, 62, or 63 during the calendar year. Instead of the standard $8,000 catch-up, that narrow age band gets a "super" catch-up of $11,250 for 2026 — the greater of $10,000 or 150% of the regular catch-up amount, indexed for inflation. Stack it on top of the regular deferral limit and someone in that four-year window can defer up to $35,750 into a 401(k) in 2026.
The same enhanced tier applies to 403(b) and governmental 457(b) plans. If you run a small business with a SIMPLE IRA instead, there's a scaled-down version: a $5,250 super catch-up for 2026 on top of a $17,000 base deferral (higher yet — $5,650 on $18,100 — for small employers using SIMPLE's enhanced-limit option), pushing the total past $22,000.
Two things trip people up:
- It's employer-optional. The higher limit only exists if your 401(k) plan document specifically allows it. Plenty of plans — especially at small businesses using an off-the-shelf provider — haven't been amended yet. Check with your plan administrator or third-party administrator (TPA) before assuming you can contribute the higher amount.
- The window is narrow and doesn't pause. Eligibility is based on the age you turn during that calendar year, not your age on any specific date. Someone who turns 64 mid-year is back to the standard $8,000 catch-up for the whole year — there's no partial-year super catch-up.
The Roth Catch-Up Trap for High Earners
Buried in the same section of SECURE 2.0 is a separate — and much more consequential — rule that has nothing to do with your age.
Starting January 1, 2026, anyone whose prior-year FICA wages from their employer exceeded $150,000 must make all of their catch-up contributions (both the standard $8,000 and, if applicable, the $11,250 super catch-up) as Roth, meaning after-tax, not pre-tax. The IRS finalized these regulations in September 2025 after a two-year administrative transition period that let plans keep accepting pre-tax catch-up contributions through the end of 2025.
The wage threshold is checked against last year's earnings from the specific employer sponsoring the plan, so a business owner who paid themselves $155,000 in W-2 wages in 2025 is a "high earner" for 2026 catch-up purposes even if this year's pay is lower. SIMPLE IRAs and SARSEPs are exempt from this mandate; everything else — 401(k), 403(b), governmental 457(b) — is in scope.
Here's the trap: if your 401(k) plan doesn't offer a Roth option, high earners can't make catch-up contributions at all — not pre-tax, not Roth, nothing — until the plan is amended to add one. For an owner-employee who was counting on maxing out a catch-up contribution to lower this year's taxable income, that's a nasty surprise to discover in December instead of January.
Plan sponsors have until December 31, 2026 to formally amend their documents, and the final regulations allow a "reasonable, good-faith interpretation" of the rule for contributions made before full compliance is required — but the practical fix is the same either way: call your plan administrator now and confirm (a) whether your plan supports the age 60-63 super catch-up, and (b) whether it has a Roth deferral option turned on. Both are yes/no questions your TPA can answer in one phone call, and both determine how much you're actually allowed to save this year.
2026 Contribution Limits at a Glance
| Plan type | Base deferral | Standard catch-up (50+) | Super catch-up (60-63) | Max possible |
|---|---|---|---|---|
| 401(k) / 403(b) / governmental 457(b) | $24,500 | $8,000 | $11,250 | $35,750 |
| SIMPLE IRA (standard) | $17,000 | $4,000 | $5,250 | $22,250 |
| SIMPLE IRA (small-employer enhanced limit) | $18,100 | $4,300 | $5,650 | $23,750 |
A worker who turns 61 this year and maxes out a standard 401(k) at $35,750 is deferring roughly $27,250 more than a 25-year-old contributing the same base $24,500 with no catch-up at all. For an owner-employee running payroll through an S-corp, that's real cash flow planning, not a rounding error — it changes what a "reasonable" W-2 salary needs to be to support the contribution.
A Worked Example
Say you're 62, run an S-corp with $180,000 in prior-year W-2 wages from your own company, and your 401(k) plan added both the Roth deferral option and the age 60-63 super catch-up this year. Two things are true at once:
- You're eligible for the $11,250 super catch-up because you turn 62 this year.
- You're also a "high earner" under the Roth mandate, because your 2025 FICA wages from this employer topped $150,000.
That means the full $11,250 catch-up has to go in as Roth — after-tax — even though your regular $24,500 base deferral can still be pre-tax (or Roth, if you elect it). Your maximum total deferral is still $35,750, but $11,250 of it reduces your take-home pay this year without lowering your taxable income, while the remaining $24,500 can still shelter income pre-tax if you choose that election.
Now compare a 61-year-old employee at the same company earning $95,000 — under the $150,000 threshold. They can put the entire $35,750 in pre-tax if the plan and their cash flow allow it, getting the full current-year tax deduction the S-corp owner doesn't get on the catch-up portion.
A Quick Action Checklist
Before you assume you can (or can't) use the higher limit, work through this in order:
- Confirm your age eligibility. You qualify for the full year if you turn 60, 61, 62, or 63 at any point in 2026 — not just if you're already that age today.
- Ask your TPA if the plan document allows the super catch-up. This is a plan-by-plan election, not automatic under SECURE 2.0.
- Pull your prior-year FICA wages from this specific employer. Over $150,000 in 2025 wages makes you a high earner for 2026 catch-up purposes.
- Confirm the plan has an active Roth deferral option if you're a high earner — without one, the catch-up contribution isn't available to you at all until the plan adds it.
- Update your payroll deferral elections with your plan provider, specifying how much (if any) of the catch-up should route to Roth vs. pre-tax.
- Flag the amendment deadline (December 31, 2026) if you're the plan sponsor and haven't formally updated your plan document yet — don't rely on informal administrator assurances alone.
Who Should Actually Use the Super Catch-Up
The extra room is most valuable for business owners in their early 60s who are:
- Behind on retirement savings after years of reinvesting profit back into the business instead of a retirement account
- In a high tax bracket now and expecting a lower bracket in retirement — the pre-tax portion (for anyone under the $150,000 wage threshold) shelters income at today's higher marginal rate
- Planning to retire or sell the business in the next few years, where the four-year eligibility window (ages 60-63) roughly lines up with the final stretch of peak earning before a lower-income retirement
If you're a high earner subject to the mandatory Roth catch-up, the math shifts: you're paying tax on that $11,250 today in exchange for tax-free growth and withdrawals later. That's not a bad deal if you expect your retirement tax rate to be similar or higher than it is now, but it's a different decision than a pre-tax deferral, and it's worth running past a CPA rather than assuming the old pre-tax math still applies.
Why This Belongs on Your Books, Not Just Your Plan Statement
Retirement contributions touch payroll, employer matching, and owner compensation all at once — which makes them easy to get right on the 401(k) provider's portal and wrong in your own financial records. If your bookkeeping doesn't clearly separate standard deferrals, catch-up amounts, and Roth vs. pre-tax treatment, reconciling your W-2 Box 12 codes at tax time turns into a scavenger hunt.
This is exactly the kind of detail that benefits from transparent, auditable records. With Beancount.io's plain-text accounting, you can tag retirement contributions by type directly in your ledger — pre-tax vs. Roth, standard vs. super catch-up — so the numbers your CPA needs at filing time are already organized instead of buried in a PDF from your plan provider.
