IHTM28150 | Liabilities: investigating liabilities: income tax
From HM Revenue & Customs · Inheritance Tax Manual
You should check that any deduction claimed for income tax liabilities
has been calculated correctly, and
does not indicate that business assets or income-producing assets have not been included in the estate.
In most cases you can accept a deduction for income tax as claimed. But you may need to raise further enquiries if:
the deduction is large () in relation to the estate as a whole or inconsistent with what you know about the deceased’s lifestyle
the liabilities arise as a result of an investigation settlement ()
the deduction claimed is an estimate ().
You also need to take special care when dealing with deductions claimed for income tax payable on:
the disposal of an offshore fund ()
the disposal of deep discount securities ()
interest bearing securities
sums received following the discontinuance of a business ()
the death of a partner in a business ()
voluntary payments of tax by the personal representatives ()
the chargeable gains arising when a life insurance policy matures ().
