OT21200 - Corporation Tax Ring Fence and Supplementary Charge

Finance Act 2002 introduced, with effect from 17 April 2002, a 10% supplementary charge on companies producing oil or gas in the UK or on the UK Continental Shelf, to be levied on their ring fence profits with no deduction for financing costs.

At the same time, special 100% first-year capital allowances were introduced for investments from 17 April 2002 in the ring fence in plant and machinery (24% for long-life assets) and mineral exploration and access.
