Use the Adjustment box for interest (
IHTM31511) only.
Never amend the tax charge by this method as it will not
match up on the SAGE (
IHTM31851) record.
There is a cash limit on the adjustment box; any case where
that limit is exceeded will need to be referred to your manager for
authorisation before the calculation can be issued.
The adjustments box is there for making minor adjustments to
the interest. There is no need to raise an assessment and
“adjust” it to nil if the amount of tax and interest is
within deminimus limits; Cashiers will simply write off the balance
on closure.
