What Andica CT600 Corporation Tax Software is
Andica CT600 Corporation Tax Software helps companies, accountants and tax advisers prepare CT600 Company Tax Returns and submit them electronically to HMRC. Version 2026 supports accounting periods up to and including 31 March 2027. It covers CT600 and supplementary forms including CT600A, CT600L, CT600M, CT600N and CT600P, and calculates tax from the accounting period and information entered on the form.
Users can attach valid iXBRL accounts and computations prepared elsewhere, or generate iXBRL data using the included template. The File By Internet function submits returns through the Government Gateway; users must already be registered with HMRC. Printed CT600 reports can be used for records and client signatures, but not for filing.
The product is offered as Windows desktop software and as a cloud application for compatible current browsers. Andica says desktop data stays on the user's computer, and desktop software includes password protection and access rights. Desktop licences are annual, tied to a version and company-record band, and require a separate licence for each computer. The listed starting prices are £50.00+VAT per year for desktop and £70/year excluding VAT for cloud.

This software is aimed at companies, accountants and tax advisers preparing CT600 returns for HMRC. The cloud edition suits users wanting browser access, while the desktop edition is for Windows users who need local data storage and desktop access controls.
