Set up mandatory Roth catch-up and contributions for retirement plans
You can set up mandatory Roth catch-up contributions by creating and activating separate deduction items for traditional and Roth retirement plans. For high-earning employees, make sure catch-up contributions are made on a Roth basis, linking the appropriate deduction items for calculation.
Provision 603 of the SECURE Act 2.0 requires that high‑earning employees—those with more than $150,000 in prior‑year FICA wages, adjusted for inflation—who are age 50 or older make all catch‑up contributions to qualified retirement plans on a Roth (after‑tax) basis beginning January 1, 2026. This requirement applies to 401(k), 403(b), and 457(b) plans.
Do the following to set up mandatory Roth catch-up contributions for employees' retirement plans:
Client-level settings
You'll need to have 2 separate deduction items—1 set up as a traditional retirement plan and 1 set up as a Roth retirement plan.
Go to the
Payroll Items
screen.
Create or verify a deduction item exists with a
Special Type
of
401(k) or 403(b)
.
Create or verify a 2nd deduction item exists with a
Special Type
of
Roth 401(k) or Roth 403(b)
.
note
The application currently doesn't support Roth 457(b) retirement plans.
Employee-level settings
Mandatory Roth catch-up contributions are configured in the
Employee Payroll Item Settings
screen of traditional 401(k) and 403(b) deduction items.
Go to the
Employees
screen then the
Payroll Items
tab.
Mark the
Active
checkbox for both deduction items for the traditional retirement plan and Roth retirement plan.
Select the ellipsis on the traditional retirement plan to open the
Employee Payroll Item Settings
window.
Mark the
Roth catch-up required (SECURE Act 2.0)
checkbox.
note
This checkbox indicates the employee is a high-wage earner based on prior-year wages and is therefore subject to mandatory Roth catch-up requirements.
In the
Linked to:
field, specify the Roth deduction item to use for calculating Rothified catch-up contributions during check entry.
note
The
Calculation Type
of the linked Roth item will change to
Linked to:
and the Rate will change to
$0.00
. This is expected behavior as this item is used to store the Rothified catch-up contributions from the parent item once they calculate.
