COM30010 - Background: company taxation overview: advance corporation tax
Advance Corporation Tax (ACT) was abolished with effect from 6 April 1999.
Arrangements for the use of surplus ACT, built up in the period to that date, substantially preserved companies� then existing expectations of its recovery.
Those expectations were achieved through a system of ‘shadow ACT�, which allowed companies to recover past surplus ACT within prescribed limits.
For further details of ACT, see COM153000 onwards.
