34Treatment of premiums etc. as rent or Schedule D profits
(1)Where the payment of any premium is required under a lease, or otherwise under the terms subject to which a lease is granted, and the duration of the lease does not exceed 50 years, the landlord shall be treated for the purposes of the Tax Acts as becoming entitled when the lease is granted to an amount by way of rent (in addition to any actual rent) equal to—
where P is the premium and Y is the number of complete periods of 12 months (other than the first) comprised in the duration of the lease.
(2)Where the terms subject to which a lease is granted impose on the tenant an obligation to carry out any work on the premises, the lease shall be deemed for the purposes of this section to have required the payment of a premium to the landlord (in addition to any other premium) of an amount equal to the amount by which the value of the landlord’s estate or interest immediately after the commencement of the lease exceeds what its then value would have been if those terms did not impose that obligation on the tenant.
(3)Subsection (2) above shall not apply in so far as the obligation requires the carrying out of work the payment for which would, if the landlord and not the tenant were obliged to carry it out, be deductible from the rent under sections 25 to 30.
(4)Where, under the terms subject to which a lease is granted, a sum becomes payable by the tenant in lieu of the whole or a part of the rent for any period, or as consideration for the surrender of the lease, the lease shall be deemed for the purposes of this section to have required the payment of a premium to the landlord (in addition to any other premium) of the amount of that sum; but—
(a)in computing tax chargeable by virtue of this subsection in respect of a sum payable in lieu of rent, the duration of the lease shall be treated as not including any period other than that in relation to which the sum is payable; and
(b)notwithstanding anything in subsection (1) above, rent treated as arising by virtue of this subsection shall be deemed to become due when the sum in question becomes payable by the tenant.
(5)Where, as consideration for the variation or waiver of any of the terms of a lease, a sum becomes payable by the tenant otherwise than by way of rent, the lease shall be deemed for the purposes of this section to have required the payment of a premium to the landlord (in addition to any other premium) of the amount of that sum; but—
(a)in computing tax chargeable by virtue of this subsection, the duration of the lease shall be treated as not including any period which precedes the time at which the variation or waiver takes effect, or falls after the time at which it ceases to have effect; and
(b)notwithstanding anything in subsection (1) above, rent treated as arising by virtue of this subsection shall be deemed to become due when the contract providing for the variation or waiver is entered into.
(6)Where a payment falling within subsection (1), (4) or (5) above is due to a person other than the landlord, no charge to tax shall arise under that subsection, but any amount which would otherwise fall to be treated as rent shall be treated as profits or gains of that other person chargeable under Case VI of Schedule D.
(7)Subsection (6) above shall not apply in relation to any payment falling within subsection (5) above unless it is due to a person who is, within the meaning of section 839, connected with the landlord.
(8)Where an amount by reference to which a person is chargeable to tax by virtue of this section is payable by instalments (“the tax instalments”), the tax chargeable by reference to that amount may, if that person satisfies the Board that he would otherwise suffer undue hardship, be paid at his option by such instalments as the Board may allow over a period not exceeding eight years and ending not later than the time at which the last of the tax instalments is payable.
(9)Section 22(2) and (3) shall not apply in relation to amounts which, in computing profits or gains for the purposes of Schedule A, are relevant only by virtue of this section.
