Chargeable gains and indexation allowances

For companies, gains or losses on disposals of assets are dealt with through corporation tax. 

The taxable gain takes inflation into account. On the HMRC pages you can find details of this indexation allowance to reduce chargeable gains.

For sole traders and partnerships, disposals of assets are dealt with through capital gains tax, usually as part of their annual self assessment return.
