Payroll Tax Update 25C - Program Funding Configuration for CT, DC, MA, WA

The program funding config is delivered inactive (as stated in the 25C documents, which detail how to activate it.) with a 1/1/2026 Effdt.

For testing purposes, our payroll area is wondering if these dates can be changed (backed up to a date in 2025, to test against a current payroll)?

Is this something that can be done (or is it a bad idea to do this)?

Thank you
