16 minutes 47 seconds

00:00:41:07 - Hi, everyone.

00:00:42:05 - Thank you for joining us today.

00:00:44:00 - My name is Julia Novia,

00:00:44:21 - Head of Full-Service Operations and Regulatory Implementation.

00:00:48:17 - And I have Janet Luxton, Senior ERISA Consultant, with me today

00:00:53:00 - to talk about the final catch-up contribution regulation.

00:00:56:18 - As most of you know, the Treasury Department and IRS did issue

00:01:00:10 - the final regulation for key catch-up provisions of the SECURE act.

00:01:05:08 - Specifically, the required Roth catch-up provision

00:01:08:22 - and optional higher catch-up provision.

00:01:11:23 - We wanted to take the time today

00:01:13:14 - to dive into what all this means, and to help answer questions

00:01:17:10 - that you might have about what has changed and what has remained the same,

00:01:22:03 - as well as some key takeaways to help you navigate the next few months

00:01:26:16 - as the effective date for the Roth catch-up provision draws near.

00:01:31:00 - We know Roth is

00:01:32:03 - complex and affects every plan differently.

00:01:35:04 - Vanguard is here to help break down the details and requirements

00:01:39:15 - to keep plan sponsors informed and prepared.

00:01:43:16 - So with that, I'm going to hand it over to Janet to go over the details.

00:01:47:10 - So while we're waiting for the slides to load, I'll just go ahead and get started.

00:01:51:05 - As Julia mentioned, we did receive the final regulation

00:01:54:08 - impacting the Roth catch-up rule, and we want to take time today

00:01:57:15 - just to give an overview of the final regulation and explain

00:02:00:19 - how it might differ from the proposed regulation we got in January of 2025.

00:02:05:22 - As you know, some of this is very nuanced.

00:02:08:11 - So a lot of the impact is going to depend on the individual client solutions.

00:02:12:08 - And how their current plan might be set up today,

00:02:15:02 - as well as the capacity of their payroll provider.

00:02:17:21 - Before I get too heavy into the final regulation,

00:02:20:13 - I'd like to give a quick overview of the Roth catch-up provision.

00:02:24:10 - Effective January 1st, 2026, employees age 50 and older

00:02:28:15 - who earned more than $145,000 in FICA wages in the previous

00:02:32:22 - calendar year from the employer sponsoring the plan, known as Roth

00:02:36:15 - catch-up required participants

00:02:38:11 - will be required to make catch-Up contributions as Roth contributions.

00:02:42:17 - Originally, plans that offered catch-up contributions without a Roth contribution

00:02:46:15 - option would have needed to stop all catch-up contributions.

00:02:50:17 - On January 13th, 2025, the IRS issued a proposed regulation

00:02:54:22 - addressing the SECURE 2.0 provisions that pertained to catch-up contributions.

00:02:59:18 - This regulation provided several points of clarification for the Roth catch-up

00:03:03:15 - provision, including that a plan can continue to offer catch-up contributions

00:03:08:06 - even if it does not allow for Roth contributions.

00:03:11:06 - That's interesting.

00:03:12:08 - So with the final regulation, what has changed?

00:03:15:05 - Can you explain more about what the final regulation is?

00:03:18:23 - Yes. Let's talk more about the final regulation.

00:03:21:20 - On September 16th, 2025, the Department of Treasury

00:03:25:05 - and the Internal Revenue Service published the long-awaited final regulation

00:03:29:11 - impacting key catch-up provisions of the SECURE 2.0 Act.

00:03:34:04 - These rules mark a significant shift in retirement plan administration,

00:03:38:02 - particularly for high income earners aged 50 and older.

00:03:41:15 - Among the notable changes is the requirement that catch-up

00:03:44:06 - contributions must be made as Roth for certain individuals, starting in 2026.

00:03:49:19 - The final regulations provide detailed guidance for plan sponsors navigating

00:03:53:19 - compliance, correction and participant elections associated with Roth

00:03:57:17 - catch-up and clarifies

00:03:59:08 - increased catch-up contribution limits for individuals ages 60 to 63.

00:04:04:10 - The final rule reflects public feedback

00:04:06:14 - and aims to balance statutory mandates with administrative flexibility,

00:04:10:21 - offering a clearer path forward for plan sponsors and participants alike.

00:04:15:02 - The biggest thing I want to call out is that there was no change

00:04:17:20 - to the effective date of January 1st, 2026, for Roth catch-up.

00:04:22:10 - As you may recall, this provision was originally set

00:04:24:20 - to take effect on January 1st, 2024.

00:04:27:23 - As a result of industry

00:04:29:05 - feedback, the IRS implemented a two-year administrative delay,

00:04:32:23 - pushing the effective date back to January 1st, 2026.

00:04:36:20 - The final regulation confirms that the effective date for Roth catch-up

00:04:40:03 - remains January 1st, 2026, with two small exceptions

00:04:44:00 - for collectively bargained plans and multiemployer plans.

00:04:47:19 - It's important to understand that while the effective date

00:04:50:12 - for the Roth catch-up remains January 1st, 2026,

00:04:53:23 - we did receive some relief with respect to applying the final regulation.

00:04:57:19 - So besides the effective date remaining the same, is there anything else of note

00:05:01:21 - that plan sponsors need to pay attention to in regard to this guidance?

00:05:05:17 - Yes. So throughout 2026, plan sponsors can comply

00:05:09:09 - with the final regulation based on a good faith interpretation.

00:05:13:02 - So they're kind of doing their best to comply with it.

00:05:15:15 - This transition period is very common from a regulatory standpoint

00:05:18:22 - when guidance comes out late. The regulation will be in full effect

00:05:22:07 - in 2027.

00:05:24:07 - We also received clarification around offering catch-up contributions in general.

00:05:29:08 - So you may remember earlier on it was thought that if a plan offered

00:05:32:12 - catch-up contributions without a Roth contribution option,

00:05:35:09 - they would have to add Roth contributions on or in order to continue

00:05:38:12 - offering catch-up contributions after January 1st, 2026.

00:05:42:13 - The final regulation confirmed that it's not required,

00:05:45:12 - so if you have a plan today that offers catch-up contributions

00:05:48:12 - without a Roth contribution option, they do not have to add it going forward.

00:05:52:19 - They can continue to allow catch-up contributions

00:05:55:06 - and will not violate the universal applicability rules.

00:05:58:08 - However, only those participants that are not subject to the Roth mandate,

00:06:02:11 - meaning those that earn under $145,000 can continue to make catch-up contributions

00:06:07:10 - after the January 1st, 2026. Roth catch-up required.

00:06:11:06 - Participants in these plans

00:06:12:12 - will not be allowed to make any catch-up contributions at all.

00:06:16:06 - The other thing the final regulation clarified

00:06:18:09 - is that a plan cannot require that all catch-up contributions be Roth.

00:06:22:20 - So this was a theory

00:06:23:19 - that some plan sponsors were exploring in order to ease administration.

00:06:27:17 - The proposed regulation noted this was not an available option,

00:06:30:22 - and the final regulation called it out even more forcefully, saying no,

00:06:35:09 - you cannot require all employees to make catch-up

00:06:37:14 - contributions as Roth contributions.

00:06:39:15 - We also get some clarity around the definition and determination

00:06:42:17 - of FICA wages.

00:06:44:03 - The final regulation clarified that FICA wages are defined as those

00:06:47:11 - that are included in box three of the W2, which is Social Security wages.

00:06:52:04 - However, the final regulation also notes that if for some reason

00:06:56:01 - the plan sponsor cannot determine FICA wages under box three of the W2

00:07:00:04 - for this transition year, then plan sponsors can use

00:07:02:21 - box five of W2 form, which is Medicare wages.

00:07:06:16 - We've had a lot of questions from plan sponsors about how to determine

00:07:10:06 - FICA wages, particularly around plans

00:07:12:05 - that have members of a control group or other participating employers.

00:07:15:19 - The good news is that the final regulation does allow employers

00:07:18:22 - to aggregate for purposes of determining that FICA wage cap.

00:07:23:00 - So if an employer sponsoring the plan is part of a controlled group,

00:07:27:04 - they can consolidate wages for purposes of determining

00:07:29:18 - whether a participant exceeds $145,000.

00:07:33:01 - They can also aggregate if they're using what's called a common paymaster.

00:07:37:15 - Another

00:07:38:01 - bit of good news from the final regulation is the clarification

00:07:41:04 - that if an individual doesn't have FICA wages for the preceding year,

00:07:44:17 - they would not be subject to that mandatory Roth catch-up provision.

00:07:48:02 - Thank you for that

00:07:48:20 - very helpful clarifying information, Janet.

00:07:51:11 - The proposed regulation talked about a deemed Roth

00:07:55:03 - election option available to plan sponsors.

00:07:58:04 - Can you talk a little bit more about this and how the final regulation

00:08:02:01 - differs from the proposed regulation issued in January?

00:08:06:09 - Certainly, much of what was in the proposed

00:08:08:16 - regulation is consistent in the final regulations, but

00:08:11:17 - we had some key clarifications around deemed Roth catch-up elections.

00:08:16:01 - So for those that may not be familiar, this concept was introduced

00:08:19:13 - by the proposed regulation.

00:08:20:23 - And it allows plan to provide that once any Roth

00:08:24:00 – catch-up required participant elects to make pre-tax contribution,

00:08:27:22 - those contributions may be automatically treated or deemed

00:08:31:07 - as Roth catch-up contributions after the participant hits

00:08:34:08 - a designated limit, be that for a 402(g), 415 or plan limit

00:08:39:01 - without having that participant need to make an affirmative catch-up election.

00:08:43:09 - This deemed Roth election option can be applied to both spillover or,

00:08:47:03 - as we call it, the single source plans, as well as separate source plans.

00:08:51:17 - Importantly, however, participants must be given an effective opportunity

00:08:56:00 - to choose a different election if plans decide to choose this option.

00:09:00:00 - The proposed regulation had very little information

00:09:02:16 - as to what effective opportunity meant, and unfortunately

00:09:06:03 - we didn't get any additional clarity there in the final regulation.

00:09:10:00 - When determining whether a participant has an effective opportunity,

00:09:13:17 - a plan sponsor will need to look

00:09:15:03 - at the facts and circumstances surrounding the situation.

00:09:18:06 - So what we do know is that there is no explicit

00:09:21:07 - notice requirement or notice period for that effective opportunity,

00:09:25:01 - but communications to participants are strongly recommended.

00:09:28:23 - We did get additional clarity on the deemed election option

00:09:31:20 - as it applies to separate source plans, which states that those plans

00:09:35:20 - are allowed to treat separate catch-up elections as Roth,

00:09:39:04 - even if those contributions

00:09:40:15 - ultimately turn out not to qualify as catch-up contribution.

00:09:44:14 - For example, say you have a participant that makes a separate election

00:09:47:23 - for Roth catch-up, but they never actually hit the 402(g) limit.

00:09:51:18 - Those monies aren't actually catch-up dollars

00:09:53:15 - but they can remain categorized as Roth monies

00:09:56:21 - and don't have to be recharacterized as pre-tax contributions.

00:10:01:00 - Is there anything else that the final regulation

00:10:03:16 - clarified with respect to the deemed Roth election option?

00:10:07:23 - Yes. A new point around the deemed Roth option

00:10:11:01 – addresses a participant's change in status.

00:10:13:19 - That is, if they no longer fall into the Roth catch-up required category.

00:10:17:18 - For example, if you're Roth catch-up required in 2026,

00:10:21:12 - but you now have reduced compensation and therefore are no longer Roth catch-up

00:10:25:22 - required in 2027, the deemed Roth catch-up election must stop

00:10:30:01 - within a reasonable period.

00:10:31:22 - Again, reasonable period is not explicitly defined in the final regulation,

0:10:36:04 - but effectively it means that you need to reset someone if they're changing status

00:10:40:13 - so that they would go back to the original deferral

00:10:42:21 - without having the deemed Roth election applied to them.

00:10:46:08 - The final regulation also clarified that if a plan is utilizing

00:10:49:20 - the deemed Roth election feature, it must be noted in the plan document.

00:10:54:06 - And lastly, we received more clarifying

00:10:56:18 - guidance around correcting Roth contribution failures,

00:11:00:02 - some of which is specific to the deemed Roth election option.

00:11:03:11 - Can you tell us a bit more about the correction methods available for Roth

00:11:07:07 - catch-up, both with respect to the deemed election option and more broadly?

00:11:12:12 - Sure.

00:11:13:10 - The proposed regulation

00:11:14:17 - outlined a number of correction methods available to plan sponsors.

00:11:18:12 - The correction method that's available to all plans,

00:11:20:23 - whether or not your deeming is a return of the erroneous pre-tax catch-up.

00:11:25:14 - So if you had a participant

00:11:26:20 - that was supposed to be a Roth catch-up required, but catch up

00:11:30:05 - contributions were made on a pre-tax basis and not a Roth basis,

00:11:34:08 - then the only way to correct that in a non-deeming situation

00:11:37:20 - is to return those catch-up contributions to the participant.

00:11:40:22 - However, if your plan is utilizing the deemed Roth election option,

00:11:45:04 - you can take advantage of two additional correction methods.

00:11:48:02 - Plan sponsors can as one option, transfer

00:11:51:01 - any pre-tax catch-up contributions that should have been Roth to

00:11:54:16 - Roth catch-up and reissue a W2. As a second option,

00:11:58:01 - the plan sponsor can complete what is effectively a Roth in-plan

00:12:01:16 – conversion and issue a 1099 to that participant.

00:12:04:21 - So plans that choose the deemed Roth election option

00:12:07:16 - get some added benefits from a correction standpoint.

00:12:11:04 - The final regulation did give us some good news

00:12:13:17 - around the flexibility and timing of corrections.

00:12:16:09 - Unlike the proposed regulations, which required uniform correction

00:12:19:19 - methods for all participants, the final regulation allows plan

00:12:23:19 - sponsors to apply corrections to similarly situated participants.

00:12:27:21 - The final regulation

00:12:29:00 - also extends correction deadlines, which vary by type of failure.

00:12:33:06 - So if you had a failure that was due to a 402(g) excess,

00:12:36:19 - the correction must be completed by the end of the taxable year

00:12:39:16 - following the year of the erroneous catch-up.

00:12:42:03 - If you had a failure for a different reason, such as exceeding the 415 limit

00:12:46:05 - or other plan limit, or an ADP failure, you have until the end of the plan

00:12:50:12 - year following the year of the failure to make that correction.

00:12:54:06 - It's important to note that the additional time for corrections

00:12:56:23 - is limited to issues involving the plan's application

00:13:00:02 - of the Roth catch-up provisions, and other corrections,

00:13:03:09 - such as tax treatment of excess deferrals, will still apply.

00:13:06:16 - Plan sponsors will want to review these correction rules carefully.

00:13:10:07 - We also got some good news around relief from the

00:13:12:23 - need to make corrections, which includes a de minimis amount.

00:13:16:06 - This means that if you have a failure that's under $250,

00:13:19:22 - you don't have to do that correction at all.

00:13:22:09 - Another instance in which a correction is not required is if a participant

00:13:26:05 - had a catch-up failure and subsequently took a full distribution of their account

00:13:30:05 - before you could get it corrected.

00:13:31:21 - So again, some good news there in the correction space.

00:13:35:13 - One more topic I want to make sure to address is dual

00:13:38:16 - qualified Puerto Rico plans.

00:13:41:01 - Does the final regulation address this? Yes.

00:13:44:13 - And we received some good news around dual qualified Puerto Rico plans.

00:13:48:07 - The proposed regulation

00:13:49:14 - contained an interesting concept for dual qualified Puerto Rico plans.

00:13:53:08 - Because Puerto Rico law does not currently allow Roth contributions to a plan,

00:13:58:02 - the proposed regulation indicated that plan sponsors of dually qualified

00:14:02:00 - Puerto Rico plans could satisfy the Roth catch-up contribution requirement

00:14:06:11 - by having traditional after-tax contributions added to the plan.

00:14:10:12 - The final regulation

00:14:11:16 - reversed this position and indicated that a dually qualified plan

00:14:15:13 - will satisfy the Roth catch-up contribution requirement

00:14:18:18 - If the plan allows Roth catch-up for only U.S.

00:14:21:13 - employees unless and until

00:14:24:02 - the Puerto Rico code is updated to provide for Roth contributions.

00:14:27:17 - Thanks, Janet.

00:14:28:19 - As our final topic, can you talk about how the final regulation

00:14:32:10 – addresses other provisions like higher catch-up. Yes.

00:14:36:11 - The final regulation did provide some additional clarity with respect

00:14:39:17 - to the higher catch-up provision, which allows participants ages 60 to 63

00:14:44:13 - to make additional catch-up contributions beyond the standard catch-up limit.

00:14:48:16 - In addition

00:14:49:05 - to confirming that the higher catch-up provision is optional for plan sponsors,

00:14:53:05 - the final regulation does provide that if a plan wants to offer higher catch-up

00:14:57:01 - limits for participants ages 60 to 63, the plan does require a plan amendment

00:15:02:04 - to allow for that optional provision, even if the plan document incorporates

00:15:06:10 - catch-up contributions by reference to Internal Revenue Code section 414 V.

00:15:10:21 - One other point of clarification for the higher catch-up provision is that

00:15:14:01 - if a plan chooses to provide higher catch-up contributions,

00:15:17:05 - it must generally offer them

00:15:18:13 - to all eligible participants under the universal availability rule,

00:15:22:14 - with the exception of collectively bargained employees and nonresident aliens.

00:15:26:23 - Therefore, a plan could prevent only non-collectively bargained employees

00:15:30:20 - ages 60 to 63 to make higher catch-up contributions

00:15:34:05 - without violating the universal applicability rule.

00:15:37:13 - Before we end, I just want to review a checklist of actions,

00:15:40:15 - particularly for the Roth catch-up provision the plan sponsors

00:15:43:18 - should be aware of as this deadline draws near.

00:15:46:20 - To ensure you're prepared for the Roth catch-up provision,

00:15:49:20 - plan sponsors should ensure your payroll provider is ready

00:15:53:13 - for January 1st, 2026, effective date.

00:15:56:23 - Get the final wage template to Vanguard

00:15:59:06 - as soon as possible after the last payroll of the year,

00:16:02:12 - and make sure your employees are informed of how they will be impacted

00:16:06:22 - before the provision takes effect on January 1st, 2026.

00:16:11:08 - Janet, thank you so much for your time today.

00:16:14:03 - We appreciate your expertise and insightful explanation.

00:16:17:20 - Thank you.

00:16:18:10 - It was a pleasure

00:16:19:05 - and I'm sure we'll be talking soon about another one of SECURE 2.0's

00:16:22:11 - many provisions as more guidance continues to be issued in the coming

00:16:26:03 - months.

00:16:27:01 - Vanguard will continue to lean into Roth catch-up resources

00:16:30:12 - to help plan sponsors implement it and navigate its complexities.

As 2025 winds down, the clock is ticking on one of the most significant retirement plan changes in recent years. The Roth catch-up contribution provision—part of the SECURE 2.0 Act—is set to take effect in 2026, and now is the time to prepare.

We understand that Roth rules can be complex and that every retirement plan is unique. That’s why we’re here to help you cut through the noise and focus on what matters most for your organization.

Our latest video explains the key updates of the final catch-up regulation, highlighting what’s changed and what remains the same compared to the proposed rule released earlier in 2025.

In this video learn how to get ahead of the curve and ensure your plan is ready for the year ahead.
