LONDON, UK. April 13th, 2026 – WeFile, a new online filing platform purpose-built for UK limited companies, enables company directors and small business owners to prepare and submit their CT600 corporation tax returns to HMRC and annual accounts to Companies House — all from a single, intuitive web application.
The platform eliminates the need for expensive accountancy software or professional intermediaries for straightforward filings, putting the power of compliance directly into the hands of business owners.
For too long, UK corporation tax filing has been a fragmented, confusing process. Company directors are forced to juggle multiple government portals, outdated software, and complex forms — or pay hundreds of pounds to an accountant for what should be a straightforward submission.
WeFile changes this by bringing the entire filing workflow into one guided, step-by-step wizard. Users are walked through every stage of the process:
- Company details — automatically fetched from Companies House using the official API
- Profit & Loss statement — with logical fields and automatic corporation tax calculation
- Balance Sheet — with real-time validation and automatic balancing checks
- Account type selection — intelligent detection of whether the company qualifies for Micro-Entity (FRS 105) or Total Exemption Full (FRS 102) accounts
- HMRC & Companies House credentials — securely entered and used only for submission
- Review & submit — preview your complete filing before sending it to both HMRC and Companies House
“We built WeFile because we believe every UK company director should be able to file their own tax return without needing a degree in accounting or spending a fortune on professional fees.”
WeFile generates fully compliant CT600 XML submissions using the HMRC GovTalk protocol. Returns are submitted directly to HMRC’s gateway, and users can track the status of their submission in real time — from acknowledgement through to final acceptance.
The platform produces iXBRL-tagged accounts in the correct inline XBRL format required by Companies House. Both Micro-Entity (abridged) and Total Exemption Full accounts are supported, along with dormant company accounts.
WeFile integrates directly with Xero, QuickBooks Online, and FreeAgent via secure OAuth connections. Users can import their trial balance data in seconds, which is automatically mapped into the CT600 computation — eliminating manual data entry entirely.
Intelligent Automation
- Auto-calculated corporation tax — enter your profit and loss figures and WeFile computes the tax due at the correct rate
- Account type detection — based on turnover, gross assets, and employee count, WeFile recommends the right accounts format
- Filing period detection — return periods are fetched directly from Companies House, so users always file for the correct dates
- Real-time balance sheet validation — ensures your assets equal liabilities plus equity before submission
Security and Compliance
- Two-factor authentication (2FA) — via authenticator app for all user accounts
- Encrypted credential handling — HMRC and Companies House credentials are used only for submission and are never stored in plain text
- OAuth-only integrations — WeFile never sees or stores passwords for Xero, QuickBooks, or FreeAgent
- Session management — users can view and revoke active sessions at any time
All submissions use official government APIs and protocols — the same channels used by professional accountancy software — ensuring full compliance with HMRC and Companies House requirements.
Unlike generic international tax platforms, WeFile is built exclusively for UK limited companies. Every feature, every form field, and every calculation is tailored to the specific requirements of:
- HMRC — Corporation Tax Self Assessment (CT600)
- Companies House — Annual accounts filing under the Companies Act 2006
- FRS 105 — The Financial Reporting Standard applicable to Micro-entities
- FRS 102 — The Financial Reporting Standard applicable in the UK and Republic of Ireland
This UK-first approach means users never have to navigate irrelevant options or translate foreign tax concepts. Everything is designed around the British tax calendar, Companies House filing deadlines, and HMRC compliance requirements.
WeFile is available now at https://wefile.co.uk. Company directors can create a free account, add their company using the Companies House company number, and begin preparing their filing immediately.
