About

CT600Filing is online Corporation Tax filing software for UK limited companies and accountancy practices. It guides users through a CT600 return, calculates Corporation Tax as figures are entered, and supports supplementary schedules such as capital allowances and R&D claims. The service generates iXBRL accounts using FRS 102 or FRS 105, or accepts accounts prepared elsewhere, then submits CT600 returns to HMRC and annual accounts to Companies House through their filing gateways. Users can prepare returns before paying, with one-off pricing per accounting period and plan options based on company size; accountant credit bundles are also available. A multi-company workspace provides filing status, deadlines, and submission history for client or group entities. The product runs online without desktop installation and serves company directors, bookkeepers, accountants, and tax professionals handling UK Corporation Tax filings.
