BIM46420 | Specific deductions: professional fees: renewal of leases
From HM Revenue & Customs · Business Income Manual
Practical approach
Professional fees incurred on the renewal of a short lease with the owner’s consent are capital but are likely to be small; in which event you may allow them on de minimis grounds. Circumstances where the amounts may be larger and where you should contend, in appropriate cases, that the expenditure is of a capital nature include those where:
the new lease is for a long term (say, a period which exceeds, or may at the lessee’s option exceed, 50 years), or
there are provisions in the lease for the payment of a premium (or for equivalent capital outlay by the lessee). In practice, the disallowance may be limited to a proportion of the expenses of renewal appropriate to the premium etc.
As regards the cost to the lessor of granting a lease, see PIM2205.
Fees in connection with legal proceedings in connection with leases may include:
the costs of resisting ejection from the premises,
obtaining a new lease in face of opposition by the landlord, or
securing statutory compensation.
Such expenses stem from the landlord’s refusal to renew the lease and you should not regard them as an admissible deduction.
