What is a catch-up contribution?
In 2023, the maximum individual contribution to a 401(k) plan is $22,500, referred to as the “standard contribution.” Participants over 50 can make an additional “catch-up contribution” of $7,500 (IRC 414(v)). When combining both contributions, the total maximum 401(k) contribution from pay is $30,000.
What is changing?
January 1, 2024, if you make more than $145,000 in 2023 and wish to make a catch-up contribution in 2024, the catch-up contribution can only be made as a Roth contribution (your standard contribution, however, can still be made as either a pre-tax or Roth contribution).
Time Period + Employer Details
The $145,00 in compensation is earned in the prior year by the employer sponsoring the 401(k) plan. For example, if you make more than $145,000 this year (2023) and are with the same employer next year (2024), your catch-up contribution must be a Roth contribution.
However, if you make more than $145,000 this year with your current employer but switch to a new employer on January 5, 2024, even if your salary with that new employer is greater than $145,000, your catch-up contribution into the new employer’s plan in 2024 could be made as either a pre-tax or Roth contribution.
This is an important point for employee education as you could potentially have two employees, both of whom make well above $145,000, but only one is required to make their catch-up contribution as a Roth contribution.
What compensation is part of the $145,000?
Section 603 states that compensation that needs to be considered is “…wages (as defined in section 3121(a)) for the preceding calendar year from the employer sponsoring the plan…” which tells, by the reference to Code section 3121(a), that the definition of “wages” is the one used for Social Security purposes (wages subject to FICA, i.e., W-2 box 5 Medicare taxable wages).
This may be different from the compensation definition used in your plan. For example, it is common for plans to use W-2 compensation; however, contributions or other items may need to be added back into that W-2 compensation to arrive at the gross compensation subject to FICA.
Not adhering to a plan’s compensation definition ranks among the top 10 compliance failures the IRS sees in its correction program. That said, the inclusion or exclusion of other forms of compensation, such as partnerships, self-employment income, etc., remains uncertain at this time.
How are recordkeepers preparing?
Many recordkeepers are notifying their clients that their systems may not be fully prepared to handle this provision by January 1. Currently, the solution is for clients to create a spreadsheet listing employees who earned over $145,000 in 2023. This spreadsheet must be provided to the recordkeeper before January 1 to “flag” accounts for the 2024 plan year.
Some recordkeepers suggest contacting payroll providers for a report, but some major providers may wait for additional guidance. As a precaution, plans should confirm with their payroll provider to ensure access to the necessary report. If not available, a new procedure for gathering information should be established, considering the holiday season surrounding the deadline.
What if I don’t currently allow Roth contributions or decide not to remove Roth contributions?
If you want to continue allowing people to make catch-up contributions, your plan will most likely need to allow for Roth contributions. Many plans still do not allow these contributions, so setting the source up effective January 1 will need to happen soon. By extension, if you decided to remove Roth contributions, your plan would likely be unable to allow catch-up contributions due to the universal availability requirement.
