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.

About

Guided, plain-English steps help users prepare a CT600 return, iXBRL accounts and a tax computation online, then file the return with HMRC and the accounts with Companies House. It supports dormant companies, micro-entities, small companies, property and investment-holding companies, charities and CICs, for periods starting as early as April 1, 2020. Preparation is free, and filing is charged per return with no subscription. Accountants can file for clients through the practice portal.
