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

Hub-Equity turns the XBRL and iXBRL filings that listed companies submit to the SEC (US) and under ESEF (Europe) into standardized income statements, balance sheets and cash flow statements for 12,500+ issuers. US-GAAP and IFRS filers share one schema, so US and European companies compare line by line. Every value links to its source filing and fiscal period. Restatements are shown side by side: original value, restated value, and the filing that changed it. Three ways to use it: - Web: company pages, screener, cross-issuer comparison, Excel/JSON export. - REST API and Python SDK (pip install hub-equity), documented at docs.hub-equity.com. - MCP server for AI agents (Claude, Cursor, Continue): pull any figure with its source filing, time series and restatements. Every plan gets the same data and checks; price scales with throughput and tooling, never with data quality. The Free plan needs no card and never expires.
