1042 taxable gross on reversal - not matching original check

We just had this happen, 10/18/2025

Nothing we can find explains what might have happened.

I did find a reference here at My Oracle Support: from an Archive;

Here is Nicole Apostola's original (now archived) thread.

Hi,

Twice this past calendar year, we have seen check reversals where the original check did not have any 1042 tax data, but when the check reversal is processed, it has 1042 taxable gross.

The employee is not set up with Tax Treaty/Non-Resident Data on Federal Tax Data.  (I've reviewed audit on this as well, and there have been no changes.)

We previously saw this in 2013.
