Grossing up applies where the trustees pay the tax from the
funds still held in the trust.
The beneficiary is effectively receiving two benefits; the
appointed/distributed sum and freedom from paying inheritance tax
on it.
Grossing up ensures that the appointed property is taxed on
the ‘loss to the settlement’ basis.
The grossing addition must always be equal to the tax
chargeable on the net chargeable value.
Grossing does not apply
If you are assessing on Compass, you can prepare a calculation to find out the tax to pay and the appropriate relief on the transferred value, but cancel it without raising an assessment.
Add a comment in the assessment notes to explain the grossing addition.
