Once an appeal has been settled by agreement you should amend
any assessment or amendment if it has been agreed that it should be
varied. If this is done automatically the tax and/or Class 4 NIC
charged by the assessment or amendment as amended will
automatically be released for collection. If you wish to suspend
collection of part or all of the revised charge you will have to
stand it over again.
If the appeal has been determined in the amount assessed, or
for other reasons the assessment is not to be amended, release any
tax etc formally postponed or informally stoodover for
collection.
