Although a license to use software is an intangible asset, it is specifically provided that capital expenditure on licensed software, and electronically transmitted software, qualifies for capital allowances as 'plant and machinery' .
If licenced software is acquired on rental, the rentals are deducted from profits over the life of the software.
If a lump sum is paid HM Revenue & Customs normally take the view that the cost of the software with an expected life of less than 2 years is written off as an expense rather than subject to capital allowances.
