Includes full support for the CT600A supplementary page (loans and arrangements to participators, s455 tax) and the CT600E supplementary page (charities and Community Amateur Sports Clubs / CASCs, covering exemption claims, income, expenditure, assets, and legacy/donor payments).

- Company Formation: Fast and simple online registration for new UK limited companies, available in two modes:
  - Self-Filer Mode: Completely free — use your own Companies House Credit Account (Presenter Account) to file directly. The only costs are the statutory Companies House fees (£100 standard / £156 same-day).
  - Formation Agent Mode: WeFile acts as an approved Companies House formation agent and handles the entire submission. No credit account needed. Pay the CH fee plus a £15 agent fee via card (£115 standard / £171 same-day).

## About WeFile

Our core principles:
- Accuracy First: Built-in validation, iXBRL tagging, and auto-calculations ensure submissions are correct.
- UK Focused: Designed exclusively for UK limited companies, ensuring tailored and specific compliance.

## Corporation Tax Rates (from 1 April 2023)
WeFile incorporates all current UK tax rates and rules:
- Small Profits Rate: 19% applied to profits under £50,000.
- Main Rate: 25% applied to profits over £250,000.
- Marginal Relief: Provides a gradual increase in the effective tax rate from 19% to 25% for profits falling between £50,000 and £250,000.
- Thresholds are proportionally divided by the total number of associated companies.
- s455 Tax (CT600A): Charged per loan at the rate in force when that loan was made: 25% before 6 Apr 2016, 32.5% from 6 Apr 2016, 33.75% from 6 Apr 2022, 35.75% from 6 Apr 2026. Relief for repayments made more than 9 months after the period end is deferred until it actually becomes due, so the s455 tax is paid now and reclaimed later via an amended return or form L2P.
