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.

Description

Effortlessly create, categorize, analyze, compute, and file CT600s through a single, user-friendly platform. Featuring the most up-to-date taxonomies and revised CT600 forms, our software enables you to prepare and submit an unlimited number of tax returns directly to HMRC online with ease. You can swiftly fill in your capital allowances additions worksheet by importing data directly from your Excel fixed asset spreadsheet. Additionally, utilize our specialized group relief and loss allocation worksheets to claim or surrender losses from the current year or those carried forward. Whether you're seeking R&D tax relief under the SME scheme with its enhanced deductions or through the large company RDEC, our tool accommodates both options. Furthermore, you can segment your profit and loss account into distinct trade and investment activities, allowing for detailed adjustments, allowances, and claims to be recorded separately in your computations. This comprehensive approach streamlines the entire tax return process while ensuring accuracy and compliance.
