Description

CT600Filing is a web-based software solution designed for UK limited companies and accounting firms to facilitate the filing of Corporation Tax returns. It provides a step-by-step process for completing a CT600 return, automatically calculating the Corporation Tax as data is entered, and accommodating additional schedules such as capital allowances and R&D claims. The platform can create iXBRL accounts compliant with FRS 102 or FRS 105, or it can accept accounts prepared by other means, and it efficiently submits CT600 returns to HMRC along with annual accounts to Companies House through their respective filing gateways. Users have the flexibility to prepare their returns before making any payments, with straightforward pricing options for each accounting period and various plans tailored to company size; there are also credit bundles available for accountants. The software includes a multi-company workspace that tracks filing statuses, deadlines, and submission histories for various client or group entities. Functioning entirely online without the need for desktop installation, it caters not only to company directors but also to bookkeepers, accountants, and tax professionals engaged in UK Corporation Tax submissions. With its user-friendly interface and comprehensive features, CT600Filing simplifies the tax filing process for all involved parties.
