If you work in PC&S you should use form Unit 4 to record
adjustments to yield on all settlement and lifetime cases. If you
work in Compliance you should to record adjustments to yield on
lifetime and settlement cases that were opened on COMPASS before
1999. The template for form Unit 4 can be found on the knowledge
tree at K:\IR Capital Taxes\Operational\I H T\Forms\Internal
Forms\Unit 3 + 4. The form is more or less self explanatory but if
you have any problems filling it in the Products and Process Team
will be able to give you advice on how to do this
You should not record adjustments to the 'historic value' of the settlement on form Unit4, but any yield you get as a result of these adjustments, especially where the account was submitted as non-taxpaying, should be included at Box D.
