Roth Catch-Up for High Earners: Not Complicated, Unless You Wait

Written by Douglas Warzinski, CFP®, CIMA® | Nov 6, 2025 8:36:45 PM

Starting 1/1/2026, SECURE 2.0 requires Roth-only catch-up contributions for HCEs. Here’s exactly what’s changing, and the simplest way to avoid getting stuck. 

For HR leaders, payroll managers, and highly compensated employees trying to stay ahead of SECURE 2.0, one mistake is proving more costly than any other. 

What’s tripping people up right now isn’t the rule. It’s the delay in acting on it. 

Across the industry, we’ve seen this pattern again and again. Plans know the change is coming. But the assumption that “someone else is handling it” has quietly become the biggest threat to compliance. 

In 2026, catch-up contributions for Highly Compensated Employees (HCEs) must be made as Roth only. 

No more pre-tax. No more choice. 

If your plan or your payroll system isn’t ready, those extra retirement contributions simply won’t happen. Even if employees elected them. Even if everyone thought it was handled. 

It’s a straightforward update… until it isn’t. And all the straightforwardness goes out the window once the clock runs out.  

Whether you’re a plan sponsor trying to stay compliant, an HCE trying to maximize savings, or the person responsible for making sure payroll and plan design align, this affects you. 

In this article, you’ll get a clear breakdown of what’s changing, what to watch for, and the simplest way to stay ahead of the rule—including what your advisor should already be doing to help you avoid a last-minute scramble. 

Let’s make this easy. 

What’s Actually Changing 

Under SECURE 2.0, any employee who: 

  • Is age 50 or older 
  • Earned $145,000 or more in the prior year
  • Wants to make catch-up contributions beyond the standard limit

…must make those contributions on a Roth (after-tax) basis starting January 1, 2026. 

That means: 

  • Pre-tax catch-up contributions are no longer allowed for HCEs 
  • Plans must offer a Roth option to stay compliant 
  • If your plan doesn’t have Roth catch-up functionality by 1/1/26, HCEs can’t make catch-up contributions at all 

Simple in theory. Messy in practice if you wait too long to implement it. 

For Plan Sponsors: Fixable, But Not at the Last Minute 

This rule was originally scheduled for 2024, but the IRS granted a two-year delay. That extra time helped, but it also led many to deprioritize this change. 

Here’s what you should be doing now: 

  • Review Your Plan Documents
    Confirm that your plan allows Roth contributions and is structured for catch-up contributions under SECURE 2.0.
  • Coordinate with Payroll
    Make sure your payroll system can:
    • Identify HCEs using prior-year compensation 
    • Route catch-up contributions correctly as Roth 
    • Block pre-tax elections where they’re no longer allowed 
  • Communicate Early and Clearly
    Let affected employees knowwhat’s changing. Clear is kind, and clear now prevents frustration later. 
  • IdentifyImpacted Employees 
    Flag HCEs now and run a test to ensure systems are aligned before the rule goes into effect. 

For High Earners: Don’t Assume It’s Handled 

If you’re over 50 and earn above the HCE threshold, this rule affects your retirement strategy directly. 

Even if your employer or advisor handles most of the details, you still have a role to play. Ask now: 

  • Does your plan offer Roth contributions? 
  • Have you reviewed your elections for 2026? 
  • Is payroll equipped to process Roth catch-up correctly? 
  • A five-minute conversation today could save you from an unpleasant surprise on your W‑2 next spring. 

What Happens If You Ignore It 

The worst strategy you can take is “Let’s all pretend this Roth rule isn’t coming and see how that goes.” 

Spoiler: it won’t go well.  

Worst-case scenario: 

  • Your plan doesn’t allow Roth, so HCEs can’t make catch-up contributions at all 
  • Payroll errors create compliance violations 
  • Highly visible employees are frustrated when their deferrals don’t process 
  • Everyone scrambles to fix it after the fact 

Better-case scenario: 
You handle it now, communicate proactively, and check this off your list for good. 

How to Make It Simple 

This rule doesn’t have to be complicated. The easiest way to keep it that way is to: 

  • Get clarity from your advisor or plan consultant now 
  • Test your systems before year-end 
  • Document your process so next year’s transition is seamless 

If your advisor isn’t helping you plan for this, ask them to start. And if they already are, you’re ahead of most. 

Need a second set of eyes? 

If you’re not 100% sure your plan is ready, or just want to confirm that nothing’s slipping through the cracks, we’re happy to take a look. It’s a quick conversation that could save a lot of time (and trouble) down the line. Reach out to the team at Carnegie if you’d like a second opinion or support getting things squared away before 2026.  

The Bottom Line 

This change is straightforward, until it isn’t. And the only difference between smooth and stressful is timing. Start now. Communicate with your advisor now. Make this a quick fix, not a compliance fire drill. SECURE 2.0’s Roth-only rule goes live January 1, 2026. Handling it now means thanking yourself later.
