There may be a number of reasons why a property is occupied rent-free or let out at rent that is less than the commercial rate. This may often occur where
the property is occupied by a family member in order to provide that person with a cheap home. For example, a parent may purchase a house in the town
where their student son attends university and let it to the student, and maybe even his housemates, at a low rent to help them out. While the parents’
motives are doubtless philanthropic, their generosity may cost them dearly when it comes to obtaining relief for the associated expenses.
Wholly and exclusively rule
Expenses can only be deducted in computing taxable rental profits if they are incurred wholly and exclusively for the purposes of the property rental business.
Unfortunately, HMRC take the view that unless the property is let at full market rent and the lease imposes normal conditions, it is unlikely that
the expenses are incurred wholly and exclusively for business purposes. So, where the property is occupied rent-free, there is no tax-relief for expenses.
If the property is let at a rent that is below the market rent, a deduction is permitted, but this is capped at the level of the rent received from the
let. This means that where a property is let at below market rent, it is not possible for a rental loss to arise, or for expenses in excess of the
rent to be offset against the rent received from other properties in the same property rental business.
Periods between lets
Where there are brief periods where the property is occupied rent-free or let out cheaply, it may be possible to obtain full relief for expenses. For example,
if the landlord is actively seeking a tenant and a relative house sits while it is empty, relief will not be restricted as long as the property remains
genuinely available for letting. In their guidance HMRC state, that ‘ordinary house sitting by a relative for, say, a month in a period of three years
or more will not normally lead to loss of relief’. However, if a relative takes a month’s holiday in a country cottage, relief for expenses incurred
in that period will be lost.
Commercial and uncommercial lets
Where a property is let commercially some of the time and uncommercially at other times, expenses should be apportioned on a just and reasonable basis
between the commercial and non-commercial lets. Any excess of expenses over rents in the period when commercially let can be deducted in the computing
the profit for the rental business as a whole. However, an excess of expenses over rent when the property is let uncommercially are not eligible for
Timing must also be considered – expenses relating to uncommercial lets cannot be deducted simply because they are incurred when the property is let commercially.
