Andica CT600 Corporation Tax Software
High Wycombe, Buckinghamshire, United Kingdom
What it is
Andica CT600 Corporation Tax Software helps companies, accountants, and tax advisers complete CT600 Company Tax Returns and submit them electronically to HMRC. Version 2026 supports accounting periods through 31 March 2027 and includes CT600 plus CT600A, CT600L, CT600M, CT600N, and CT600P supplementary forms. Tax calculations are generated automatically from the accounting period and information entered. Users can attach valid iXBRL accounts and computations prepared elsewhere or create iXBRL data with the included template. That template has limited predefined fields, omits some FRS 102 tagging, and excludes FRS 105 micro-entity accounts. File By Internet sends returns through the Government Gateway after HMRC registration. Printed CT600 reports are available for records and client signatures, but paper reports cannot be filed. The product has Windows desktop and browser-based cloud editions. Desktop data stays on the user's computer, according to Andica, while desktop licences are annual, version-specific, computer-specific, and limited by company-record bands.
