Computation preview

Computation Preview provides a summary of the company’s corporation tax details, including:

  • Unique Tax Reference
  • Profit per the accounts
  • Total tax profit
  • Corporation tax payable

It also includes expandable analysis schedules which provide additional information in support of the tax calculation. The schedules summarise the computation data entered and will therefore vary from company to company.

You are not able to enter details directly on to either the Calculation Summary or the supporting schedules. You should enter these on the computation data screen.

From the top of Tax Calculation, you have options to:
