BIM58610 - Historic houses: grants
The owners of historic properties may receive grants conditional on arrangements being made for public access to the property. These grants are intended to defray the whole or part of the cost of repairs or maintenance.
Where used wholly or partly to meet revenue expenses attributable to the opening of the property to the public, a grant (or the due proportion of it) should be taken into account in computing the taxable trade profits. For further information on the treatment of these grants, see BIM40450 onwards.
