Specific deductions: rent and rates: Falkirk & Lennard cases
There may be occasions where a trader, under an obligation entered into for trade purposes, continues to pay rent for premises which are no longer exclusively used for those purposes. In this situation, the difference between the rent paid and any rent received forms an admissible deduction in computing the profits if the trader either:
- sublets the whole or part of the premises at a loss; or
- leaves them wholly or partly empty.
See CIR v Falkirk Iron Co Ltd  17 TC 625 and Hyett v Lennard  23 TC 346.
Although the decisions in the two cases mentioned above related to periods after the premises had ceased to be used for the purposes of the trade, the same principles are regarded as applying to periods before the premises commenced to be occupied for those purposes.
