Usually a rental business begins when letting first commences.
Allowable revenue expenditure incurred before the rental business begins can be relieved under the ICTA88/S401 or ITTOIA05/S57, provisions for pre-trading expenditure. Relief is only due if the expenditure:
- is incurred wholly and exclusively for the purposes of the rental business
- is not capital expenditure
- is incurred within a period of seven years before the date the rental business is started, and
- is not otherwise allowable as a deduction for tax purposes, and
- would have been allowed as a deduction if it had been incurred after the rental business started.
Thus, for example, council tax on a property could be allowable under the above rules if it is due before the property is first let, provided the property was acquired solely for the purposes of the rental business. However, the relief is not allowable if the council tax was paid on the taxpayer’s own private residence before the property was let (as it would be the taxpayer’s own expense).
Qualifying pre-letting expenditure is treated as incurred on the day on which the taxpayer first carries on their rental business. So, any repairs carried out before the letting starts can still be deducted from the first year’s gross rents.
