Andica CT600 Corporation Tax Software vs ONESOURCE Income Tax

Andica CT600 Corporation Tax Software prepares CT600 Company Tax Returns and submits them electronically to HMRC. It is aimed at companies, accountants, and tax advisers. Version 2026 supports accounting periods through 31 March 2027 and includes CT600 plus CT600A, CT600L, CT600M, CT600N, and CT600P supplementary forms. Tax calculations use the accounting period and entered form data. Users can attach iXBRL accounts and computations made elsewhere or generate 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 reports support records and signatures but cannot be filed with HMRC. The product has Windows desktop and browser-based cloud editions. Desktop data stays on the user's computer, according to Andica, with password protection and access rights.

ONESOURCE Income Tax has no write-up on Specifiction yet; its figures are above.
