CA31400 | IBA: Qualifying expenditure: Expenditure on the construction of a building
From HM Revenue & Customs · Capital Allowances Manual
You should give IBA on capital expenditure incurred on the construction of a building or the capital cost of buying an unused building.
Expenditure incurred on the construction of a building includes:
capital expenditure on repairs, that is expenditure on repairs for which a Case 1 deduction could not be made CA31450;
the costs of demolishing an existing building in order to erect a new building provided that those costs are not taken into account in calculating a balancing adjustment on the old building;
professional fees relating to the design and construction of a building provided that the building is actually constructed;
and so you should give IBA on those costs.
Expenditure on the construction of a building does not include:
the cost of obtaining planning permission. If, however, a builder’s quotation includes the cost of obtaining planning permission do not try to disallow that part of the quotation;
capitalised interest;
the cost of a public enquiry;
the cost of land drainage and reclamation;
landscaping;
legal expenses;
and so these costs do not qualify for IBA.
