Introduction to accounting methods: GAAP
This guidance applies to periods of account beginning before 1 January 2005
Generally accepted accounting practice (GAAP) is defined in ICTA88/S836A(1) for periods of account beginning before 1 January 2005. It means, in relation to the accounts of UK companies, the GAAP used so that those accounts show a true and fair view.
Where the requirements of the tax legislation conflict with GAAP, the company must make an adjustment to ensure that the computations follow the legislation for tax purposes. For example
it is required accounting practice for a company using the accruals basis to make bad debt provisions. This provision is not recognised for tax purposes when the debtor and creditor are connected.
The following guidance looks at the specific requirements for each method.
