Updated Earn Types – Qualified Overtime (FLSA)

-
OT
-

-
OT-AL
-
OT-AL-Weighted
For these earn types, the system will calculate the qualified overtime premium as follows:
-
Divide the total overtime amount by the rate multiplier (Company Setup > Earnings > Rate x field), and
-
Divide the result in half.
Note: When the rate multiplier is blank the total overtime amount is divided by 1, then divided in half.
These earn types should be used when paying qualified overtime subject to FLSA requirements.
New Earn Types – Non-Qualified Overtime (Non-FLSA)
The following new earn types have been added to support payment of non-qualified overtime:
-
OT-NQ – Non-FLSA Overtime
-

These earn types should be used when overtime does not meet the definition of qualified overtime under OBBBA.

This memo earn type can be used to override the qualified overtime amount reported on the 2026 Form W-2, when necessary.
System: Paid Family Leave Tax with Successorships Update (M3-2720)
The system has been updated to exclude any paid family leave in successorship company relationships. To enable the system to recognize a successorship, add an S to the FUTA other 1 return Option on the Parent company. The FICA has been added back so the aggregate will pick it up.
