You can setup a threshold limit for K-1 Ownership percentage from here.
Go to Admin > Account Setup > K1-Threshold tab.
The default K1-Treshold percentage is 25%.
You can change the K1-threshold percentage as per your firm's requirement. Change the percentage and click on "Update" button.
If the ownership percentage on any K-1 exceeds the threshold defined here, then the system will list the related business return as 'Missing' if it is not identified in the scanned documents.
Note:
This threshold will have no other impact on any other functionality.
