[F1(a)income charged at [F2an applicable] rate were charged at the basic rate, and

(b)income charged at the dividend additional rate or the dividend upper rate were charged at the dividend ordinary rate.]

[F3(3A)For the purposes of subsection (3), each of the following is an “applicable rate”—

(a)the higher rate,

(b)the additional rate,

(c)any Scottish rate that—

(i)is above the Scottish basic rate, but

(ii)is not the Scottish intermediate rate,

(d)the Welsh higher rate, and

(e)the Welsh additional rate.]

(4)The amount of the reduction under subsection (2) is calculated as follows:

Step 1

Calculate the net pre-death income by subtracting from the pre-death income any liabilities which have been taken account both—

(a) in determining the value of D's estate for the purposes of inheritance tax, and

(b) in calculating the residuary income of D's estate for the tax year.

Step 2

Calculate the inheritance tax attributable to net pre-death income by multiplying the inheritance tax to be charged by—

Step 3

Gross up the inheritance tax attributable to net pre-death income by reference to the basic rate for the tax year.

(5)The amount of pre-death income taken into account in determining the value of D's estate is taken to be the actual amount of income accruing before D's death, less income tax at the basic rate for the tax year in which D died.

(6)Subsection (5) applies even if the income so accruing was not valued separately or its amount was not known at the date of D's death.

(7)For the purposes of this section, the amounts agreed between the persons liable for inheritance tax and [F4an officer of Revenue and Customs] , or determined in proceedings between them, as the value of the estate and the amount of inheritance tax to be charged are conclusive.

(8)Evidence of those amounts and of any facts relevant to their calculation may be given by the production of a document that appears to be a certificate from [F4an officer of Revenue and Customs]
