During migration of SA records to the CID framework a matching
exercise takes place to identify any duplicate live records which
already exist on TBS. Where a duplicate case is identified a work
item will be created on Work List W050 for the taxpayer record that
was passed through from SA. The work item will show the UTR, NINO
and EMPREF for the duplicate case that exists on TBS.
You should review both taxpayer records to establish which
one contains the most up to date information and then decide which
case to make dormant.
Note: Any activity on this to set-up and close
down records will generate SA250 and SA251 welcome and exit
letters. Whenever you are working either of the cases identified as
potential duplicates you should use Function AMEND TAXPAYERS
SIGNALS to set the ‘SA Entry / Exit Letter Inhibited’
signal on both records.
After migration
The Action Guides in section ‘Set Up Taxpayer
Record’ in this business area stress the need to establish
that there is neither a live nor dormant SA record before you set
up a new SA record. However, following the migration process, there
will still be instances when duplicate records are created in
error.
When a new taxpayer record is set up on SA and a duplicate
live SA record with a different UTR already exists on TBS, a work
item will be created on the W050 ‘CID Framework
Rejection’ Work List. The work item will be created for the
taxpayer record that was passed through from SA and will show the
UTR, NINO and EMPREF for the duplicate case that exists on TBS.
In all cases where a duplicate live record exists the newly
created record should be made dormant. You should review both
taxpayer records to establish what action has been taken on each
record. If a return has already been issued from the newly created
record take the action detailed in subject ‘Duplicate SA
Records’ (
SAM101100).
