Section 526: Writing off expenditure for periods when building not used as qualifying dwelling-house
1829.This section is based on section 90(5) of CAA 1990. It writes off part of the qualifying expenditure attributable to the dwelling-house for any period, after it is first used, during which the dwelling-house is not a qualifying dwelling-house. The write off is at the rate at which writing-down allowances could have been given during that period if the dwelling-house had been a qualifying dwelling-house.
1830.The rate at which writing-down allowances could have been given might vary during the period when the dwelling-house is not a qualifying dwelling-house. If so, the write off is found by splitting the period into periods during which the rate is the same and adding together the write-offs appropriate to each of those periods.
