Hi E,
Income from the sale of timber from the ownership of commercial woodlands is exempt from both Income Tax and Corporation Tax - the exemption only applies if the timber cut or felled is not altered or transformed prior to sale profits arising from the occupation of commercial woodlands are not chargeable.
Capital Allowances cannot be claimed on capital expenditure incurred on plant or machinery connected with commercial woodlands.
Note that if the woodland is connected with or attached to an existing farming trade, special consideration will have to be given as to the tax status of the operation.
Relief is not available for:
losses suffered expenditure incurred on the preliminary clearance of woodland of woodland or other preparation of land for forestry purposes. Further giudance is here:

Thank you.
