(1)M1In computing for the purposes of Schedule A the profits or gains arising to a person (the “person chargeable”) in any chargeable period, the amounts of any permitted deductions shall be deducted from rent to which he becomes entitled under a lease in that period.
(2)M2In this section—
“permitted deductions” means any payments, except any payment of interest, made by the person chargeable in respect of any of the following matters—
maintenance, repairs, insurance or management;
any services provided by him otherwise than by way of maintenance or repairs, being services which he was obliged to provide but in respect of which he received no separate consideration;
rates or other charges on the occupier which the person chargeable was obliged to defray;
any rent, rentcharge, ground annual, feuduty or other periodical payment reserved in respect of, or charged on or issuing out of, land;
being payments which are deductible in accordance with subsections (3) to (9) below and section 26; and
“void period” means a period during which the person chargeable was not in occupation of the premises or any part thereof but was entitled to possession thereof.
(3)M3There may be deducted from rent to which the person chargeable becomes entitled in a chargeable period the amount of any permitted deduction which became due in that period, or at an earlier time falling within the currency of the lease, in so far as the payment—
(a)was made in respect of the premises comprised in the lease, and
(b)in the case of a payment for maintenance or repairs, was incurred by reason of dilapidation attributable to a period falling within the currency of the lease or, in the case of any other payment, was incurred in respect of such a period.
(4)Where the person chargeable became the landlord after the lease began, references in subsection (3) above to the currency of the lease shall not include any time before he became the landlord.
(5)M4In the case of a lease at a full rent, subsection (3) above shall have effect as if references to the currency of the lease included any period (“a previous qualifying period”)—
(a)during which the person chargeable was the landlord in relation to a previous lease of the premises, being a lease at a full rent; or
(b)which was a void period beginning either with the termination of an earlier lease at a full rent of the premises or with the acquisition by the person chargeable of the interest in the premises giving him the right to possession thereof;
but a period shall not be a previous qualifying period if it preceded a period ending before the beginning of the lease which was not itself a previous qualifying period.
(6)Where during any period the conditions necessary for the period to be a previous qualifying period were fulfilled as respects part of the premises, but not the whole, the period shall be treated as a previous qualifying period as respects that part of the premises only, and subsection (5) above shall have effect accordingly, any necessary apportionment being made of rent, payments or other matters.
(7)M5In the case of a lease at a full rent, not being a tenant’s repairing lease, there may also be deducted the amount of any payment made in respect of other premises by the person chargeable—
(a)in so far as that amount could be deducted under subsections (3) and (5) above from rent to which he became entitled in the chargeable period under a lease of those other premises, being a lease at a full rent, or could be so deducted if that rent were not insufficient, or
(b)if any part of the chargeable period is, in respect of those other premises, a void period beginning with the termination of a lease at a full rent, in so far as the amount could be so deducted if the lease had continued until the end of the period.
(8)M6Where by reason of any change of circumstances a lease ceases to be, or becomes, a tenant’s repairing lease, or ceases to be, or becomes, a lease at a full rent, subsections (5) and (7) above shall apply in relation to the lease as it subsists after the change of circumstances as if it were a new lease granted when the change occurred.
(9)M7Where the person chargeable retains possession of a part of the premises and that part is used in common by persons respectively occupying other parts of the premises, this section shall apply as if a payment made in respect of the part used in common had been made in respect of those other parts.
