About

CT600Filing is online Corporation Tax filing software for UK limited companies, directors and accountants. A guided, step-by-step process helps you prepare your CT600 and iXBRL accounts, then file the return with HMRC and the accounts with Companies House from one account. Corporation Tax, including marginal relief, is calculated as you go, and errors are checked before you submit. Every submission is tracked, with HMRC’s response and a PDF of the return to download. Supports dormant, FRS 105 micro, FRS 102 Section 1A small and full FRS 102 accounts, for periods up to 18 months. Prepare free and pay only when you submit. Prices start at £49 + VAT for a nil CT600 with dormant accounts. Companies House filing is included on every plan. No subscription, nothing to install, and free amendments to the same return. Accountants get white-label filing under their practice name, one dashboard for all clients, CSV trial balance import and credit bundles from £10.99 per filing.
