Let's talk about catch-up contributions the way real people talk about them — without the IRS word salad.

If you're 50 or older and still working, Congress gives you the ability to put extra money into your employer plan each year. Sounds simple enough. But in 2025, we have two catch-up rules, two age ranges, inflation adjustments, and a Roth-only twist that kicks in later.

So here's the skinny for how catch-ups really work in 2025, what changes when you hit ages 60–63, and why everyone is confused about whether these contributions need to be pre-tax or Roth.

Let's walk through it together.

The "Clean" Version

Start with the clean version: If you're 50 or older, you can contribute more. That's the heart of it.

Once you turn 50 at any point in the year, you unlock the standard catch-up contribution in your employer plan. For 2025, it's $7,500.

Think of it like this: You have the regular contribution limit (around $23,500) — and then, once you hit 50, you get to tack on the extra catch-up. The important part is that once you qualify, you continue to qualify every year after. That part never changes.

The "Roth-Only" Catch-Up Rule (SECURE 2.0)

Let's talk about the specific Catch-Up requirement that people keep mixing up. Congress created a rule in SECURE 2.0 that affects high earners in employer-sponsored plans (like 401(k)s and 403(b)s). It does not apply to IRAs.

Here is the rule: If you earned more than $145,000 (indexed to $150,000 for 2025 wages) in FICA wages from that specific employer in the prior year, your catch-up contributions must be designated as Roth.

• Not optional.

• Not partial.

• Not "I prefer pre-tax, thank you."

• Just Roth.

Here's the part most people miss: This rule was originally supposed to start in 2024, but the IRS delayed enforcement until 2026 so payroll systems could catch up.

So, for 2025, high earners in employer plans still have the freedom to choose how they treat their catch-up contributions:

• Pre-tax

• Roth

• Or a mix

The Bottom Line: After 2026, high earners in workplace plans lose the pre-tax option for catch-ups. Until then, the choice is still yours.

The "Super Catch-Up" (Ages 60–63)

Now let's get into the new twist: ages 60–63.

Starting in 2025, Congress wanted to give workers closer to retirement an even bigger runway. So they created what people are calling the "super catch-up."

First, the Account Types: This rule applies ONLY to Workplace Plans (401(k), 403(b), and governmental 457(b)).

• Standard Traditional and Roth IRAs are not eligible.

• SIMPLE IRAs are eligible, but they use lower limits (see below).

The Amounts (The "Gotcha"): The rule states the Super Catch-Up is the higher of $10,000 or 150% of the regular catch-up limit in 2024. Because of this specific "2024" wording in the tax code, the math doesn't always equal exactly 150% of the current year's catch-up.

Here are the confirmed hard numbers from the IRS:

401(k), 403(b), and Governmental 457(b) Plans For these major workplace plans, the "Super Catch-Up" stays flat in 2026, even though the standard catch-up rises.

• 2025 Limits

• Standard Catch-Up (Age 50+): $7,500

• Super Catch-Up (Age 60–63): $11,250

• 2026 Limits

• Standard Catch-Up (Age 50+): Increases to $8,000

• Super Catch-Up (Age 60–63): Remains flat at $11,250

SIMPLE IRA Plans Similar to the larger plans, the SIMPLE IRA "Super Catch-Up" does not increase in 2026.

• 2025 Limits

• Standard Catch-Up (Age 50+): $3,500

• Super Catch-Up (Age 60–63): $5,250

• 2026 Limits

• Standard Catch-Up (Age 50+): Increases to $4,000

• Super Catch-Up (Age 60–63): Remains flat at $5,250

Key Takeaway for 2026 Planning: Notice that while the Standard Catch-Up is increasing to $8,000 in 2026, the Super Catch-Up is staying flat at $11,250. (It does not jump to $12,000 as simple math might suggest.)

The "Age Band" Rule: This age band—60 to 63—is the only time someone can use this larger bucket.

• Age 59? Not eligible (use standard catch-up).

• Age 64? Back to the normal/standard catch-up.

Quick note about how these two catch-ups interact.

If you're age 60–63, you don't stack the catch-ups. There's no two-for-one layering. You simply use the bigger one.

The 2025 "Super Catch-Up" (Age 60–63)

• Standard Deferral Limit: $23,500 (Up from $23k)

• Enhanced Catch-Up: $11,250

• Total Capacity: $34,750

The Standard Catch-Up (Age 50–59 & 64+)

• Standard Deferral Limit: $23,500

• Standard Catch-Up: $7,500

• Total Capacity: $31,000

It's the same setup — just a different allowance depending on the birth year.

A question that always comes up: "Does the employer match apply to catch-ups?"

Most plans do. Some plans don't. It depends entirely on the employer's plan document.

There's no IRS restriction that says "you can't match catch-ups." It's purely a plan-specific design choice.

One new twist from SECURE 2.0: If the plan chooses to, employers can now make Roth matching contributions. That's brand new. Some companies already rolled it out. Some won't. All plan-dependent.

Another thing people mix up: compensation caps and contribution limits.

Just because you're eligible for catch-ups doesn't mean the employer plan ignores other IRS limits.

• The regular compensation limit still applies.

• The annual additions limit still applies.

• Highly Compensated Employee testing still applies.

• Payroll systems still apply.

In other words, catch-ups give you a bigger contribution bucket — but they don't override every other rule in the book.

Don't confuse employer-plan catch-ups with IRA catch-ups.

This is another area where people get tangled.

IRA catch-up:

• turns on at age 50

• $1,000 for 2025

• Inflation-adjusted (finally rising to $1,100 in 2026)

• same number for everyone

• no Roth-only requirement

• has nothing to do with wages

• totally separate from employer plan rules

Employer-plan catch-up (401k, 403b, etc.):

• much higher

• inflation adjusts

• split into standard and enhanced

• Roth-only requirement for high earners starting in 2026

• tied to wages

• depends on the plan

• includes match considerations

The only thing these two categories share is the phrase "catch-up." Beyond that, they don't interact.

So why is everyone confused?

Because Congress layered multiple changes across multiple years, across multiple systems, across multiple types of accounts. And they all sound similar.

You've got age rules, wage rules, inflation indexing, IRS delays, employer plan differences, and two catch-up buckets in a single system.

People hear one piece, or something half-remembered, or something their coworker said, and suddenly every conversation starts with: "Wait… I thought catch-ups had to be Roth now?"

Not yet. Not for 2025. This is why your Substack exists — to clean up the noise.

The simple summary (no jargon)

Here's the whole catch-up structure boiled down to one clean sentence:

In 2025, anyone 50 or older gets a standard catch-up, anyone age 60–63 gets a bigger enhanced catch-up instead, and starting in 2026, anyone who earned more than $145k (indexed) in wages must make all catch-ups as Roth.

That's it.
That's the rule without the chaos.
