Take a client who is 61, three years from retiring, and earning more than she ever has. The kids are launched, the mortgage is small or gone, and for the first time in her working life she has room in the budget. She wants to know how much of it she can move into the plan before the window closes. For most of her career the answer was the standard deferral plus the age-50 catch-up. Since 2025 there is a better answer, available for four years of her life. Someone has to know it exists and confirm her plan allows it.
The mechanics
Beginning in 2025, a participant who is 60, 61, 62, or 63 by year-end can make an enhanced catch-up contribution equal to the greater of $10,000 or 150 percent of the standard catch-up. For both 2025 and 2026 that math lands at $11,250. The regular age-50 catch-up is $8,000 in 2026, so a 60-to-63 participant gets an extra $3,250 of tax-advantaged room, on top of the elective deferral limit (which for 2026 is $24,500).
A 62-year-old in 2026 who maxes out can contribute $24,500 plus $11,250. Across the four-year window that compounds into a number that can extend a retirement runway, and it matters most for the person who got a late start or took years out of the workforce to raise kids or care for a parent.
The provision is optional for plans
Advisors get into trouble here. Plans can choose whether to offer the higher tier. IRS guidance, including Notice 2025-67, lays out the limits, but a plan can run the standard catch-up and skip the enhanced tier entirely. The provision's presence in the law tells you nothing about whether a particular plan supports it.
The first job is verification. Before you promise anyone a bigger number, confirm two things: that the plan document adopted the higher tier, and that the recordkeeper and payroll system are coded to accept it. Promising a contribution the payroll file will not take leads to an uncomfortable call. Pull the document language, then get a person at the recordkeeper to confirm it.
This is also where one clean source of truth per plan pays off. When the adopted provisions, the recordkeeper, and the document sit in one place you can open, a question like "does this plan allow the super catch-up" takes a minute instead of an afternoon of digging through email. A system of record like PlanSync 360 is built to hold that. Either way, do not skip the check.
The window closes at 64
For the year a participant turns 64, the standard catch-up limit returns, with no phase-down. A client gets four years at this, ages 60 through 63, and then the number drops.
That detail changes the advice. You want to plan around this provision early, while there is time to free up cash flow, time a bonus, or rethink how a married couple funds two separate plans. The value sits in the lead time, which is why it belongs in a review now.
The Roth wrinkle for high earners
If your 60-to-63 client is a high earner, set expectations up front. Under the Roth catch-up rule taking effect in 2026, a participant whose prior-year FICA wages from that employer were above $145,000 (indexed, and $150,000 for the relevant year) must make catch-up contributions on a Roth basis. The enhanced $11,250 may not go in pre-tax. For a well-paid executive a few years from retirement, that is a real planning point. It interacts with their current marginal rate, what they expect to pay in retirement, and any Roth conversion thinking already on the table. Know which side of the wage line the client sits on before the meeting.
A script you can use
Keep the client conversation simple. You are answering four questions:
- Do you qualify? You need to be 60, 61, 62, or 63 by the end of the year.
- How much more does it allow? Up to $11,250 in catch-up for 2026 instead of the standard $8,000, on top of the $24,500 deferral limit.
- What does that do for the runway? Put it in their numbers: four years of extra contributions plus the growth on them, landing right before they need the money.
- What do we confirm? That the plan offers it, that payroll is coded for it, and whether the catch-up has to go in as Roth.
That ten-minute conversation can change the last leg of someone's working life, and participants remember that kind of attention.
Where the advice lives
An optional provision in the tax code is worth nothing to a participant until somebody puts it into operation. Build the habit: verify the plan adopted it, confirm the recordkeeper and payroll coding will take the higher amount, and document the election so the file tells the story later.
The recordkeeper will not call your client to mention the window is open, and payroll will not flag that she just turned 60. The gap between a provision that exists and a provision that gets used is why an advisor is in the room. Four years goes by fast, and someone has to be watching her calendar.
