Regarding the existing rule T2 due date is calculated 3 months after FYE basically, we need to add a new rule to recalculate due date 1 month after receiving info from client. Pls find the definition of new rule as follows
If doc received date filled in then do not allow early due date on specific form.
If existing early due date specified on form, then it takes priority, otherwise:
If the Docs received date is before the File year and Y/E date then due date should be 1 month after File year and year end but not after regularly calculated due date.
If the Docs received date is after File Year and Y/E and after document requested date, then the due date is 1 month after the doc’s received date, unless it is after regularly calculated due date in which case the existing rule applies.
If the docs received date is not filled in, then existing rule applies.
