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 supplementary forms CT600A, CT600L, CT600M, CT600N, and CT600P. Tax calculations are generated from the accounting period and information entered. Users can attach valid iXBRL accounts and computations prepared elsewhere or create iXBRL data with the built-in template. That template has limited predefined fields, lacks all 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 support records and client signatures but cannot be filed with HMRC. The product has Windows desktop and cloud editions. Andica says desktop data stays on the user’s computer, with password protection and access rights. Desktop licences are annual, version-specific, limited by company-record bands, and require a licence per computer. The cloud edition runs in a compatible current browser. Desktop pricing starts from £50.00+VAT per year; cloud pricing is £70/year excluding VAT. There is no free plan.
