About

Leverage technology to eliminate tedious, repetitive tasks. Our platform allows your team to automate manual and error-prone processes to achieve greater efficiency, accuracy, and insights. Aggregate data from multiple sources, ensure data quality, calculate your VAT obligations and submit returns to the HMRC. Wrangling ERP data to calculate TP charges or intragroup pricing? Use the platform with any data source, apply your version of any TP method and visualize the impact. Instead of a precarious spreadsheet to calculate your PAYE Settlement Agreement (PSA) use managed employee data to process expenses. Feed salary data through and make sure never to miss a calculation. ARKK helps automate processes of the finance function. By replacing outdated tools with smart technology, finance teams are empowered to unify, process, and gain insights from their data more quickly and accurately than ever before.

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.
