2A

Where the person entitled to the relevant interest in relation to any capital expenditure incurred on the construction of a building or structure incurs an additional VAT liability in respect of any of that capital expenditure, then—

a

that liability shall be regarded for the purposes of this Act as capital expenditure incurred by him on the construction of the building or structure, and

b

the residue (as defined in section 8(1)) of the expenditure incurred on the construction of the building shall accordingly be deemed for the purposes of this Part to be increased as at the time at which the liability is incurred by an amount equal to the liability.

2B

Where an additional VAT liability is incurred as mentioned in subsection (2A) above, then (subject to any further adjustment under this subsection on any later such event or under subsection (2C) or (3) below) the writing-down allowance for any chargeable period, if that chargeable period or its basis period ends after the time at which the liability is incurred, shall be the residue of the capital expenditure immediately after the incurring of the liability, reduced in the proportion (if it is less than one) which the length of the chargeable period bears to the part unexpired, at the date of the incurring of the liability, of the period of 25 years beginning with the time when the building or structure was first used.

2C

In any case where—

a

an additional VAT rebate in respect of any capital expenditure incurred on the construction of a building or structure is made to the person entitled to the relevant interest in relation to that expenditure, and

b

the residue of that expenditure immediately before the making of the rebate is not less than the amount of the rebate,

then (subject to any further adjustment under this subsection on any later such event or under subsection (2B) above or (3) below) the writing-down allowance for any chargeable period, if that chargeable period or its basis period ends after the time at which the rebate is made, shall be the residue of that expenditure immediately after the making of the rebate, reduced in the proportion (if it is less than one) which the length of the chargeable period bears to the part unexpired, at the date of the making of the rebate, of the period of 25 years beginning with the time when the building or structure was first used.
